05:29 PM Revision 3207: VegBIEN: Fixing import issue related to duplicate entries in tables with children, where when a new table entry duplicates an existing entry, the 1:1 tables of that table and those tables' children are not merged, causing them to become orphaned. It is described in detail at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/Import_issues#Merging-duplicates-with-children>, including the rationale for this solution. Note that this is *not* a bug in column-based import, it applies to row-based import as well. This commit fixes the issue for locationevent->location in plots data, by also mapping locationevent's unique keys to location.sourceaccessioncode and setting location.datasource_id.
Aaron Marcuse-Kubitza
03:59 PM Revision 3206: sql.py: DbConn.run_query(): Separate the data source comment from the query with a tab in the executed query but a \r in the logged query, so that the query will be shown on the same line as the data source comment in pg_stat_activity, but be hidden by the following line when cating the file and be put on a separate line when viewed in a text editor. This causes the first line of the query to be at the left edge when the log file is viewed, so that it looks more natural.
Aaron Marcuse-Kubitza
03:15 PM Revision 3205: README.TXT: Data import: Import data into VegBIEN: Added command to use for column-based import
Aaron Marcuse-Kubitza
02:10 PM Revision 3204: schemas/vegbien.sql: locationevent: Allow a locationevent to be uniquely specified by its location (which is now datasource-scoped) and start date
Aaron Marcuse-Kubitza
01:26 PM Revision 3203: VegBIEN: Fixing import issue related to duplicate entries in tables with children, where when a new table entry duplicates an existing entry, the 1:1 tables of that table and those tables' children are not merged, causing them to become orphaned. It is described in detail at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/Import_issues#Merging-duplicates-with-children>, including the rationale for this solution. Note that this is *not* a bug in column-based import, it applies to row-based import as well. This commit fixes the issue for specimenreplicate->...->location, by also mapping specimenreplicate's unique keys to location.sourceaccessioncode and setting location.datasource_id.
Aaron Marcuse-Kubitza
12:47 PM Revision 3202: schemas/vegbien.sql: locationevent: Allow to be uniquely specified by location_id. This is useful for specimens data where there is one location for every locationevent.
Aaron Marcuse-Kubitza
12:27 PM Revision 3201: schemas/vegbien.sql: location: Added datasource_id and sourceaccessioncode so locations can be uniquely specified by the input datasource, rather than being created automatically for each locationevent
Aaron Marcuse-Kubitza
11:45 AM Revision 3200: schemas/filter_ERD.csv: Add back taxondetermination->taxonoccurrence fkey because that has been replaced by a trigger in the SQL
Aaron Marcuse-Kubitza
11:06 AM Revision 3199: VegBIEN: Fixing import issue related to duplicate entries in tables with children, where when a new table entry duplicates an existing entry, the 1:1 tables of that table and those tables' children are not merged, causing them to become orphaned. It is described in detail at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/Import_issues#Merging-duplicates-with-children>, including the rationale for this solution. Note that this is *not* a bug in column-based import, it applies to row-based import as well. This commit fixes the issue for specimenreplicate->taxonoccurrence.
Aaron Marcuse-Kubitza
07:40 AM Revision 3198: inputs/import.stats.xls: Updated with remaining stats from most recent import
Aaron Marcuse-Kubitza

07/02/2012

03:52 PM Revision 3197: PostgreSQL-MySQL.csv: Remove INHERITS clauses
Aaron Marcuse-Kubitza
02:37 PM Revision 3196: schemas/vegbien.ERD.mwb: Fixed lines
Aaron Marcuse-Kubitza
02:24 PM Revision 3195: db_xml.py: put_table(): Moved in_row_ct updating to Subsetting section so the cursor's rowcount can be used directly
Aaron Marcuse-Kubitza
02:18 PM Revision 3194: db_xml.py: put_table(): Subsetting in_table: Don't count # rows because this takes awhile for large datasets. Instead, use the chunking algorithm in digir_client, which ends the loop when a partial or empty partition is encountered.
Aaron Marcuse-Kubitza
01:58 PM Revision 3193: inputs/import.stats.xls: Updated with new stats from an independent import
Aaron Marcuse-Kubitza
01:20 PM Revision 3192: schemas/vegbien.sql: Fixed UNIQUE INDEXes that were still using COALESCE(..., 0) to use COALESCE(..., 2147483647) in order to match what sql_gen.EnsureNotNull uses
Aaron Marcuse-Kubitza
12:41 PM Revision 3191: schemas/vegbien.sql: specimenreplicate: UNIQUE INDEX on catalognumber_dwc: Added collectioncode_dwc so that datasources that specify it in addition to the institution_id (such as aggregators) will not need to have catalognumbers be unique within an institution
Aaron Marcuse-Kubitza
12:30 PM Revision 3190: inputs/import.stats.xls: Updated with more stats from latest import
Aaron Marcuse-Kubitza
11:44 AM Revision 3189: inputs/import.stats.xls: Updated with initial stats from latest import. Reformatted to put successive runs of column-based next to each other, so they could be directly compared and so that the row-based data wouldn't need to be duplicated. Added empty-value checks to formulas so that they don't need to be manually deleted when one of their inputs is empty.
Aaron Marcuse-Kubitza
10:32 AM Revision 3188: input.Makefile: Documentation: import/steps.by_col.sql: Fixed bug where needed to run import in test mode
Aaron Marcuse-Kubitza
10:12 AM Revision 3187: sql_io.py: put_table(): Don't set pkeys of missing rows to default value if out_table is a SQL function, because then there is already an entry for every row
Aaron Marcuse-Kubitza
10:03 AM Revision 3186: bin/map: by_col: Reuse existing out_db connection for in_db instead of opening separate connection
Aaron Marcuse-Kubitza
09:50 AM Revision 3185: sql.py: mk_select(): Replaced newlines with spaces when query is simple enough to fit on one line
Aaron Marcuse-Kubitza
09:40 AM Revision 3184: db_xml.py: put_table(): Set db.src to help identify the data source in pg_stat_activity
Aaron Marcuse-Kubitza
09:39 AM Revision 3183: sql.py: DbConn: Added src config param, which in autocommit mode, will be included in a comment in every query, to help identify the data source in pg_stat_activity
Aaron Marcuse-Kubitza
09:38 AM Revision 3182: sql_gen.py: Added lstrip() to remove comments
Aaron Marcuse-Kubitza
09:13 AM Revision 3181: sql.py: mk_insert_select(): Added src param to help identify the data source in pg_stat_activity
Aaron Marcuse-Kubitza
08:33 AM Revision 3180: mappings/DwC2-VegBIEN.specimens.csv: Mapped institutionCode. This will enable datasources to use specimenreplicate's institution_id index for duplicate elimination.
Aaron Marcuse-Kubitza
08:31 AM Revision 3179: input.Makefile: Prompt user to accept test, instead of providing command line func for doing so
Aaron Marcuse-Kubitza
07:45 AM Revision 3178: schemas/vegbien.sql: specimenreplicate: UNIQUE INDEX on catalognumber_dwc: Added institution_id so that datasources that specify it (such as aggregators) will not need to have catalognumbers be globally unique. Once the institution_id is mapped to, this will fix a bug where rows with the same catalognumber were assumed to be duplicates even though they were from different institutions. This should also avoid the need to do any duplicate elimination joins when importing specimenreplicate, speeding up column-based import.
Aaron Marcuse-Kubitza
07:32 AM Revision 3177: schemas/vegbien.sql: specimenreplicate: Renamed museum_id to institution_id to correspond with DwC's institutionCode, so that it would be more obvious where to map institutionCode fields to
Aaron Marcuse-Kubitza
07:16 AM Revision 3176: inputs/import.stats.xls: Updated to include run times for rest of datasources for most recent column-based import
Aaron Marcuse-Kubitza

06/29/2012

08:09 AM Revision 3175: db_xml.py: put_table(): Subsetting in_table: Prepend schema to subset table name so that in pg_stat_activity, it's clear which datasource a particular query is from
Aaron Marcuse-Kubitza
07:46 AM Revision 3174: sql_io.py: cast_temp_col(): add_col()'s distinguishing comment param: Add the type in case the same input column is being cast to different types, and both types have the same first word (causing their new column names to be the same)
Aaron Marcuse-Kubitza
07:42 AM Revision 3173: sql_io.py: cast_temp_col(): Name the new column with only the first word of the type, to save space in the limited identifier length
Aaron Marcuse-Kubitza
07:41 AM Revision 3172: strings.py: Added first_word()
Aaron Marcuse-Kubitza
07:35 AM Revision 3171: sql_io.py: cast_temp_col(): Use sql_gen.suffixed_col() to create the new column name
Aaron Marcuse-Kubitza
06:16 AM Revision 3170: inputs/import.stats.xls: Added run time for SALVIAS organisms, which just finished
Aaron Marcuse-Kubitza
06:14 AM Revision 3169: inputs/import.stats.xls: Use [1]-style footnotes because copying and pasting to Gmail doesn't preserve the superscripts
Aaron Marcuse-Kubitza
06:11 AM Revision 3168: inputs/import.stats.xls: Updated for latest simultaneous column-based import
Aaron Marcuse-Kubitza
04:42 AM Revision 3167: sql_io.py: cast_temp_col(): Don't automatically create an index on the new column, because it doesn't necessarily need an index and the main index used for the join is now added automatically by distinct_table()
Aaron Marcuse-Kubitza
04:39 AM Revision 3166: sql.py: flatten(): Don't automatically create indexes on all columns, because most columns don't need indexes and the main index used for the join is now added automatically by distinct_table()
Aaron Marcuse-Kubitza
04:35 AM Revision 3165: sql.py: Removed no longer needed add_index_col() and ensure_not_null() because we are not using index columns
Aaron Marcuse-Kubitza
04:33 AM Revision 3164: sql.py: add_index(): Don't create index columns for nullable columns, because they require indexes to be created on all columns in order to use a distinct_table() temp table. Also, now that we are no longer using LEFT JOINs, the COALESCE() call would only be evaluated once (in the plain JOIN) in the event that PostgreSQL doesn't use an index on a COALESCE() expression.
Aaron Marcuse-Kubitza
03:30 AM Revision 3163: schemas/vegbien.sql: location: Dropped unique constraint on lat/long because it covered only some rows, which interfered with column-based import's selection of different insert methods based on the presence or absence of duplicate keys. (With the constraint, locations with coordinates would have duplicates eliminated, but locations without coordinates would not be able to find which row was added for a particular location because there was no lookup key to join on, and would all just use the first inserted row.) The previous behavior didn't make much sense anyway, because it would assert that two locationevents occurred in the same place just because they had the same coordinates, which may not have been precise enough to make this determination. Asserting that two locationevents occurred in the same place is really part of the secondary validation, not the import process.
Aaron Marcuse-Kubitza
01:58 AM Revision 3162: sql.py: DbConn: Fixed bug where Exceptions did not have the query appended if the query was not run in cacheable mode, by moving _add_cursor_info() from DbCursor.execute() to run_query() so it would also get called for non-cacheable queries that use a native cursor rather than a wrapper. Fixed bug where non-cacheable queries were not autocommitted, by moving self.do_autocommit() from DbCursor.execute() to run_query() so it would also get called for non-cacheable queries that use a native cursor rather than a wrapper.
Aaron Marcuse-Kubitza
01:54 AM Revision 3161: sql.py: DbConn._db(): Record that a transaction is already open before setting the search_path so that a query is never run with an _savepoint value less than 1 (manual transactions are not supported yet)
Aaron Marcuse-Kubitza
01:52 AM Revision 3160: sql.py: DbConn.with_savepoint(): Increment _savepoint before running queries so they don't get autocommitted
Aaron Marcuse-Kubitza
01:10 AM Revision 3159: sql.py: empty_temp(): Empty temp tables even in debug_temp mode, so that it can be seen which tables have been garbage collected and disk space leaks can be detected. This will not affect the external re-runnability of slow queries in debug_temp mode, as long as the user aborts the debug_temp import while the slow query is still running.
Aaron Marcuse-Kubitza
01:07 AM Revision 3158: sql_gen.py: ColDict: Use OrderedDict so that order of keys in input dict (if ordered) will be preserved. This should ensure that tempt table unique indexes have their columns in the same order as the output table, so that a merge join can be used.
Aaron Marcuse-Kubitza
01:01 AM Revision 3157: util.py: dict_subset(): Use OrderedDict so that order of keys in input dict (if ordered) will be preserved
Aaron Marcuse-Kubitza
12:55 AM Revision 3156: main Makefile: python-Darwin: Added pip installation instructions. python-Linux: Added ordereddict.
Aaron Marcuse-Kubitza
12:04 AM Revision 3155: sql.py: DbConn.col_info(): cacheable param defaults to True now that callers explicitly turn off cacheable when needed
Aaron Marcuse-Kubitza
12:00 AM Revision 3154: sql.py: add_index_col(): Explicitly set update()'s col_info caching depending on whether col_info will be changed later by add_not_null()
Aaron Marcuse-Kubitza

06/28/2012

11:55 PM Revision 3153: sql.py: mk_update(): Renamed cacheable param to cacheable_ so it wouldn't conflict with update()'s cacheable param
Aaron Marcuse-Kubitza
11:54 PM Revision 3152: sql.py: mk_update(): Added cacheable param to set whether column structure information used to generate the query can be cached
Aaron Marcuse-Kubitza
11:40 PM Revision 3151: sql.py: add_index_col(): Explicitly set col_info()'s caching depending on whether col_info will be changed later by add_not_null()
Aaron Marcuse-Kubitza
11:35 PM Revision 3150: sql.py: DbConn.col_info(): Allow caller to specify whether query is cacheable
Aaron Marcuse-Kubitza
11:22 PM Revision 3149: csv2db: Fixed bug where CREATE TABLE statement was cached, causing it not to be re-executed after a rollback due to a failed COPY FROM. Avoid re-creating the table after a failed COPY FROM, and instead just remove any existing rows.
Aaron Marcuse-Kubitza
11:09 PM Revision 3148: sql.py: add_index(): Don't generate a unique name for the index because the database does that automatically
Aaron Marcuse-Kubitza
11:00 PM Revision 3147: csv2db: Vacuum table instead of just reanalyzing it because for some reason reanalyzing it isn't enough to fix the cached row count (causing pgAdmin3 to report that the table needs to be vacuumed)
Aaron Marcuse-Kubitza
10:54 PM Revision 3146: csv2db: Don't add indexes on the created table because they use up more disk space than the table itself and currently aren't used. (The import process adds indexes on each iteration's column subset instead.)
Aaron Marcuse-Kubitza
10:21 PM Revision 3145: db_xml.py: partition_size: Turning partitioning back on (with a larger limit), since the largest datasources' temp tables are still too big
Aaron Marcuse-Kubitza
10:20 PM Revision 3144: sql_io.py: put_table(): Fixed bug where if there were multiple unique constraints that were violated, only the distinct temp table for the last one would get garbage-collected
Aaron Marcuse-Kubitza
09:01 PM Revision 3143: db_xml.py: partition_size: Set to sys.maxint to disable partitioning. The last bugfix, which avoided returning a large result set to the client which was never read, seems to have fixed the disk space leak, so it's worth reattempting a full simultaneous import.
Aaron Marcuse-Kubitza
08:30 PM Revision 3142: db_xml.py: put_table(): Subsetting in_table: Truncate in_table when finished with it, to avoid temp table disk space leaks
Aaron Marcuse-Kubitza
07:56 PM Revision 3141: sql.py: insert_select(): If caller is only interested in the rowcount (if returning == None), keep the NULL rows for each insert on the server using CREATE TABLE AS. (CREATE TABLE AS sets rowcount to # rows in query, so rowcount will still be set correctly.)
Aaron Marcuse-Kubitza
04:59 PM Revision 3140: top-level map: Added support for custom public schema, to be able to run imports and tests simultaneously (e.g. on a dev machine)
Aaron Marcuse-Kubitza

06/27/2012

10:56 PM Revision 3139: csv2db: Fixed bug where table needed to be a sql_gen.Table object with the proper schema, so that errors_table would be created in the correct schema. Removed no longer needed changing of the search_path.
Aaron Marcuse-Kubitza
10:55 PM Revision 3138: csv2db: Fixed bug where table needed to be a sql_gen.Table object with the proper schema, so that errors_table would be created in the correct schema. Removed no longer needed changing of the search_path.
Aaron Marcuse-Kubitza
10:12 PM Revision 3137: sql.py: DbConn.with_savepoint(): Open a new transaction if one is not already open
Aaron Marcuse-Kubitza
10:11 PM Revision 3136: sql.py: DbConn: _savepoint starts at 1 because the driver is not in autocommit mode, so a transaction is already open
Aaron Marcuse-Kubitza
10:05 PM Revision 3135: sql.py: DbConn: _savepoint starts at 1 because the driver is not in autocommit mode, so a transaction is already open
Aaron Marcuse-Kubitza
09:31 PM Revision 3134: csv2db: Create errors table first, so that imports can start using it right away
Aaron Marcuse-Kubitza
09:25 PM Revision 3133: input.Makefile: Added import/steps.by_col.sql to generate a Redmine-formatted list of steps for column-based import
Aaron Marcuse-Kubitza
08:56 PM Revision 3132: bin/map: Optimized default verbosities for the mode: automated tests should not be verbose, column-based import should show all queries to assist profiling, and row-based import should just show row progress
Aaron Marcuse-Kubitza
08:43 PM Revision 3131: sql_io.py: put(): Run data import queries with log_level=3.5 so they don't clutter the output at the normal import verbosity of 3
Aaron Marcuse-Kubitza
08:27 PM Revision 3130: db_xml.py: put_table(): Work around PostgreSQL's temp table disk space leak by reconnecting to the DB after every partition
Aaron Marcuse-Kubitza
08:26 PM Revision 3129: sql.py: mk_select(): Also support limit and start values of type long
Aaron Marcuse-Kubitza
08:13 PM Revision 3128: sql_gen.py: suffixed_table(): Fixed bug where needed to copy *all* table attrs, such as is_temp status
Aaron Marcuse-Kubitza
08:05 PM Revision 3127: sql.py: create_table(): Fixed bug where needed to run query in recover mode in case the table exists and was created before the current connection, such that the CREATE TABLE statement would not have been cached
Aaron Marcuse-Kubitza
07:50 PM Revision 3126: sql.py: create_table(): Removed final newline after query because that's added by the logging mechanism
Aaron Marcuse-Kubitza
07:43 PM Revision 3125: sql.py: Added reconnect()
Aaron Marcuse-Kubitza
07:37 PM Revision 3124: sql.py: DbConn._reset(): Assert that _savepoint is 0 instead of setting it to 0
Aaron Marcuse-Kubitza
07:31 PM Revision 3123: db_xml.py: put_table(): put_table_(): Removed no longer used limit, start params
Aaron Marcuse-Kubitza
07:23 PM Revision 3122: db_xml.py: put_table(): Merged partitioning and subsetting into same section for simplicity, to avoid creating extra temp tables, and to later allow the connection to be closed and reopened between partitions. partition_size: Expressed value without exponent notation to ensure that it's an integer.
Aaron Marcuse-Kubitza
07:11 PM Revision 3121: db_xml.py: put_table(): Partitioning in_table: Adjust bounds of last partition to actual row #s included
Aaron Marcuse-Kubitza
06:43 PM Revision 3120: sql.py: DbConn: Added _ to reset() to indicate that it's a protected method and users should not call it directly
Aaron Marcuse-Kubitza
06:41 PM Revision 3119: sql.py: DbConn.close(): Reset the connection completely using reset()
Aaron Marcuse-Kubitza
06:40 PM Revision 3118: sql.py: DbConn: Added clear_cache() and reset() and use reset() in __init__()
Aaron Marcuse-Kubitza
06:31 PM Revision 3117: bin/map: Use new DbConn.close()
Aaron Marcuse-Kubitza
06:31 PM Revision 3116: sql.py: DbConn: Added close()
Aaron Marcuse-Kubitza
06:07 PM Revision 3115: db_xml.py: partition_size: Set to just more than the size of the largest data source that was successfully imported in simultaneous import
Aaron Marcuse-Kubitza
05:32 PM Revision 3114: db_xml.py: put_table(): Partition in_table if larger than a threshold. The threshold is initially set to disable partitioning. Partitioning will hopefully eliminate the excessive disk usage for large input tables, which has caused the system to run out of disk space due to what may be a bug in PostgreSQL.
Aaron Marcuse-Kubitza
05:27 PM Revision 3113: db_xml.py: put_table(): Set in_table's default srcs to in_table itself instead of sql_gen.src_self, so that any copies of in_table will inherit the same srcs instead of being treated as a top-level table. This ensures that the top-level table's errors table will always be used.
Aaron Marcuse-Kubitza
05:17 PM Revision 3112: sql_io.py: cast(): Always convert exceptions to warnings if the input is a column or expression, even if there is no place to save the errors, so that invalid data does not need to be handled by the caller in a (much slower) extra exception-handling loop
Aaron Marcuse-Kubitza
04:47 PM Revision 3111: sql_io.py: put_table(): MissingCastException: When casting, handle InvalidValueException by filtering out invalid values with invalid2null() in a loop
Aaron Marcuse-Kubitza
04:45 PM Revision 3110: sql_io.py: cast_temp_col(): Run sql.update() in recover mode in case expr produces errors. Don't cache sql.update() in case this function will be called again after error recovery.
Aaron Marcuse-Kubitza
04:40 PM Revision 3109: sql.py: Generalized FunctionValueException to InvalidValueException so that it will match all invalid-value errors, not just those occurring in user-defined functions
Aaron Marcuse-Kubitza
04:22 PM Revision 3108: sql_io.py: put_table(): Removed no longer used sql.FunctionValueException handling, because type casting functions now do their own invalid value handling
Aaron Marcuse-Kubitza
03:44 PM Revision 3107: db_xml.py: put_table(): Subsetting in_table: Call put_table() recursively using put_table_() to ensure that limit and start are reset to their default values, in case the table gets partitioned (which needs up-to-date limit and start values)
Aaron Marcuse-Kubitza
03:14 PM Revision 3106: sql_io.py: put_table(): mk_main_select(): Fixed bug where the table of each cond needed to be changed to insert_in_table because mk_main_select() uses the distinct table rather than the full input table
Aaron Marcuse-Kubitza
03:12 PM Revision 3105: sql_gen.py: with_table(): Support columns that are wrapped in a FunctionCall object
Aaron Marcuse-Kubitza
02:47 PM Revision 3104: sql_gen.py: index_cols: Store just the name of the index column, and add the table in index_col(), in case the table is ever copied and renamed
Aaron Marcuse-Kubitza

06/26/2012

11:06 PM Revision 3103: Moved error tracking from sql.py to sql_io.py
Aaron Marcuse-Kubitza
11:04 PM Revision 3102: sql_io.py: put_table(): Use sql.distinct_table() to uniquify input table, instead of DISTINCT ON. This avoids letting PostgreSQL create a sort temp table to store the output of the DISTINCT ON, which is not automatically removed until the end of the connection, causing database bloat that can use up the available disk space.
Aaron Marcuse-Kubitza
10:36 PM Revision 3101: sql_gen.py: suffixed_table(): Use concat()
Aaron Marcuse-Kubitza
10:34 PM Revision 3100: sql_gen.py: with_default_table(): Remove no longer used overwrite param
Aaron Marcuse-Kubitza
10:33 PM Revision 3099: sql.py: distinct_table(): Return new table instead of renaming input table so that columns that use input table will continue to work correctly
Aaron Marcuse-Kubitza
10:31 PM Revision 3098: sql_gen.py: Moved NamedCol check from with_default_table() to with_table()
Aaron Marcuse-Kubitza
09:39 PM Revision 3097: sql.py: distinct_table(): Fixed bug where empty distinct_on cols needed to create a table with one sample row, instead of returning the original table, because this indicates that the full set of distinct_on columns are all literal values and should only occur once
Aaron Marcuse-Kubitza
09:12 PM Revision 3096: sql.py: run_query(): DuplicateKeyException: Fixed bug where only constraint names matching a certain format were interpreted as DuplicateKeyExceptions. Support constraint names with the name and table separated by ".", not just "_".
Aaron Marcuse-Kubitza
09:10 PM Revision 3095: sql.py: run_query(): Exception parsing: Match patterns only at the beginning of the exception message to avoid matching embedded messages in causes and literal values
Aaron Marcuse-Kubitza
08:46 PM Revision 3094: sql.py: Added distinct_table()
Aaron Marcuse-Kubitza
08:46 PM Revision 3093: sql_gen.py: Added with_table() and use it in with_default_table()
Aaron Marcuse-Kubitza
07:52 PM Revision 3092: sql.py: mk_insert_select(): ignore mode: Support inserting all columns when cols == None
Aaron Marcuse-Kubitza
07:47 PM Revision 3091: sql_gen.py: Col, Table: Support non-string names
Aaron Marcuse-Kubitza
07:25 PM Revision 3090: sql_gen.py: row_count: Use new all_cols
Aaron Marcuse-Kubitza
07:24 PM Revision 3089: sql_gen.py: Added all_cols
Aaron Marcuse-Kubitza
07:17 PM Revision 3088: sql_gen.py: Use new as_Name() instead of db.esc_name()
Aaron Marcuse-Kubitza
07:12 PM Revision 3087: sql_gen.py: Name: Truncate the input name
Aaron Marcuse-Kubitza
07:11 PM Revision 3086: sql_gen.py: Added Name class and associated functions
Aaron Marcuse-Kubitza
06:46 PM Revision 3085: sql.py: create_table(): Support creating temp tables. This fixes a bug in copy_table_struct() where the created table was not a temp table if the source table was. copy_table_struct(): Removed no longer needed versioning because that is now handled by create_table().
Aaron Marcuse-Kubitza
06:33 PM Revision 3084: sql.py: Added copy_table_struct()
Aaron Marcuse-Kubitza
06:32 PM Revision 3083: sql.py: Moved add_indexes() to Indexes subsection
Aaron Marcuse-Kubitza
06:30 PM Revision 3082: sql.py: create_table(): Support LIKE table
Aaron Marcuse-Kubitza
05:18 PM Revision 3081: Moved Data cleanup from sql.py to sql_io.py
Aaron Marcuse-Kubitza
05:18 PM Revision 3080: Moved error tracking from sql.py to sql_io.py
Aaron Marcuse-Kubitza
05:12 PM Revision 3079: sql.py: Organized Database structure introspection and Structural changes functions into subsections
Aaron Marcuse-Kubitza
04:56 PM Revision 3078: Moved error tracking from sql.py to sql_io.py
Aaron Marcuse-Kubitza
04:46 PM Revision 3077: Moved Heuristic queries from sql.py to new sql_io.py
Aaron Marcuse-Kubitza
04:32 PM Revision 3076: Added top-level analysis dir for range modeling
Aaron Marcuse-Kubitza
04:02 PM Revision 3075: sql.py: run_query_into(): Documented why analyze() must be run manually on newly populated temp tables
Aaron Marcuse-Kubitza
03:57 PM Revision 3074: sql.py: DbConn: Added autoanalyze mode. Added autoanalyze() which runs analyze() only if in autoanalyze mode. Use new autoanalyze() in functions that change a table's contents.
Aaron Marcuse-Kubitza
03:52 PM Revision 3073: sql.py: run_query_into(): analyze() the created table to ensure the query planner's initial stats are accurate
Aaron Marcuse-Kubitza

06/25/2012

09:46 PM Revision 3072: inputs/SpeciesLink/src: Added custom header that overwrites existing header so that column names will not be too long for the staging table
Aaron Marcuse-Kubitza
09:35 PM Revision 3071: cat_csv: Support overwriting the existing header using a separate header file
Aaron Marcuse-Kubitza
08:49 PM Revision 3070: schemas/vegbien.sql: Added location.location_coords index to speed up large imports by providing an index for merge joins
Aaron Marcuse-Kubitza
08:43 PM Revision 3069: csv2db: Reanalyze table, so that query planner stats are up to date even though the table doesn't need to be vacuumed anymore
Aaron Marcuse-Kubitza
08:42 PM Revision 3068: sql.py: Added analyze()
Aaron Marcuse-Kubitza
08:11 PM Revision 3067: csv2db: Removed no longer needed table vacuum (cleanup_table() now avoids creating dead rows)
Aaron Marcuse-Kubitza
08:10 PM Revision 3066: sql.py: cleanup_table(): Use update()'s new in_place mode to avoid needing to vacuum the table
Aaron Marcuse-Kubitza
08:02 PM Revision 3065: sql.py: mk_update(): in_place: Support updating multiple columns at once
Aaron Marcuse-Kubitza
07:44 PM Revision 3064: sql.py: update() calls: Use in_place where possible to avoid creating dead rows, which bloats table size
Aaron Marcuse-Kubitza
07:37 PM Revision 3063: sql.py: DbConn.col_info(): Support user-defined types
Aaron Marcuse-Kubitza
07:33 PM Revision 3062: sql_gen.py: Added Nullif
Aaron Marcuse-Kubitza
07:27 PM Revision 3061: sql_gen.py: Added Coalesce class and use it in EnsureNotNull
Aaron Marcuse-Kubitza
07:15 PM Revision 3060: sql_gen.py: Added coalesce and use it in EnsureNotNull
Aaron Marcuse-Kubitza
07:00 PM Revision 3059: sql.py: DbConn.col_info(): Don't cache the structure query because the column type, etc. may change between calls. This fixes a bug in mk_update() where the column type would be retrieved before a NOT NULL constraint was added, causing the NOT NULL constraint not to be in the cache info about the column.
Aaron Marcuse-Kubitza
06:56 PM Revision 3058: sql.py: mk_update(): Implemented in_place mode
Aaron Marcuse-Kubitza
06:39 PM Revision 3057: sql.py: mk_update(): Factored out filtering of input values so only `.to_str(db)` is used inline in the creation of the query
Aaron Marcuse-Kubitza
06:32 PM Revision 3056: sql.py: mk_update(): Added in_place param
Aaron Marcuse-Kubitza
06:13 PM Revision 3055: csvs.py: TsvReader: Prevent "new-line character seen in unquoted field" errors by replacing '\r' with '\n'
Aaron Marcuse-Kubitza
06:12 PM Revision 3054: csv2db: Adding indexes: Fixed bug where sql.add_index()'s ensure_not_null param needed to be renamed to ensure_not_null_
Aaron Marcuse-Kubitza
05:16 PM Revision 3053: sql.py: cast(): columns values clause: Use start=0 to avoid "SELECT statement missing a WHERE, LIMIT, or OFFSET clause" warning
Aaron Marcuse-Kubitza
02:45 PM Revision 3052: inputs/import.stats.xls: Updated for most recent run
Aaron Marcuse-Kubitza

06/22/2012

07:46 PM Revision 3051: sql.py: Removed no longer needed mk_track_data_error()
Aaron Marcuse-Kubitza
07:45 PM Revision 3050: sql.py: track_data_error(): Use for loop and insert() (ignoring DuplicateKeyException) to insert entries into the errors table, to get the same optimization benefits this change provides in other filter-out contexts, and to improve clarity
Aaron Marcuse-Kubitza
07:35 PM Revision 3049: sql.py: cast(): Use FOR loop with EXCEPTION block instead of CROSS JOIN with LEFT JOIN to insert entries into the errors table, to get the same optimization benefits this change provides in other filter-out contexts, and to improve clarity
Aaron Marcuse-Kubitza
07:31 PM Revision 3048: sql_gen.py: NamedValues: Support None cols param for no named columns
Aaron Marcuse-Kubitza
06:55 PM Revision 3047: sql.py: ensure_not_null(): Made the use of index columns configurable based on the # of rows in the table, because for small datasources, they seem to add 6-25% to the total import time
Aaron Marcuse-Kubitza
06:12 PM Revision 3046: xml_func.py: _noCV: Fixed bug where assumed items was an iterator when it's now a list
Aaron Marcuse-Kubitza
06:02 PM Revision 3045: sql.py: add_index_col(), cast_temp_col(): Cache add_col() by providing new comment param to distinguish new columns of the same (colliding) suffixed name but from different source columns
Aaron Marcuse-Kubitza
05:54 PM Revision 3044: sql.py: add_index_col(), cast_temp_col(): Cache the update that fills in the new column, since it's idempotent
Aaron Marcuse-Kubitza
05:52 PM Revision 3043: sql.py: update(): Pass cacheable to run_query()
Aaron Marcuse-Kubitza
05:48 PM Revision 3042: sql.py: add_col(): Added comment param which can be used to distinguish columns of the same name from each other when they contain different data, to allow the ADD COLUMN query (and related queries, such as adding indexes) to be cached
Aaron Marcuse-Kubitza
05:46 PM Revision 3041: sql_gen.py: Added esc_comment()
Aaron Marcuse-Kubitza
05:37 PM Revision 3040: sql.py: DbConn.DbCursor.execute(): Allow ADD COLUMN to be cached if it has a distinguishing comment, because then the rest of query will be unique in the face of name collisions
Aaron Marcuse-Kubitza
05:29 PM Revision 3039: sql.py: add_col(): Document that name may be versioned, so caller needs to propagate any renaming back to any source column for the TypedCol
Aaron Marcuse-Kubitza
05:27 PM Revision 3038: sql.py: add_col() callers: Removed column name versioning because that is now handled by add_col()
Aaron Marcuse-Kubitza
05:22 PM Revision 3037: sql.py: add_col() callers: Fixed bug where needed to propagate any renaming of typed column back to regular column
Aaron Marcuse-Kubitza
05:19 PM Revision 3036: sql.py: add_col(): Version column names to avoid collisions. (Previously, callers were required to do this themselves.)
Aaron Marcuse-Kubitza
05:13 PM Revision 3035: sql.py: cast_temp_col(): Handle column name collisions like add_index_col()
Aaron Marcuse-Kubitza
04:49 PM Revision 3034: sql.py: mk_insert_select(): INSERT IGNORE: Switched to using FOR loop rather than cursors because cursors are only needed if you want to process multiple rows in the same EXCEPTION block (which you can't do because then all the previous inserts will be rolled back if one row is a duplicate key)
Aaron Marcuse-Kubitza
04:40 PM Revision 3033: sql.py: mk_insert_select(): INSERT IGNORE: Moved FETCH FROM cursor outside EXCEPTION block since only the insert needs to have unique_violations ignored
Aaron Marcuse-Kubitza
04:33 PM Revision 3032: sql.py: put_table(): Removed no longer needed EXCLUSIVE lock on the output table
Aaron Marcuse-Kubitza
04:25 PM Revision 3031: add_index_col(): Run all operations with log_level=3 because it is the equivalent of creating an index, and that has log_level=3 to be excluded from the primary algorithm steps. add_not_null(): Run query with log_level=3 because it's an internal operation and for add_index_col() above.
Aaron Marcuse-Kubitza
04:23 PM Revision 3030: sql.py: update(): Pass any log_level to run_query()
Aaron Marcuse-Kubitza
04:11 PM Revision 3029: xml_func.py: process(): Added pass-through optimization for aggregating functions with one arg
Aaron Marcuse-Kubitza
04:02 PM Revision 3028: xml_func.py: process(): Call list() on the items' iterator so that its length can be determined wherever it's used without needing to call list() on it separately
Aaron Marcuse-Kubitza
03:43 PM Revision 3027: sql.py: mk_select(): Put '*' on same line as 'SELECT' if there is no DISTINCT ON, to avoid extra newlines
Aaron Marcuse-Kubitza
03:38 PM Revision 3026: sql_gen.py: NamedTable.to_str(): Put AS clause on same line as code being named if it didn't contain a newline, to avoid extra newlines
Aaron Marcuse-Kubitza
03:29 PM Revision 3025: sql.py: run_query(): Always parse exceptions, whether recover is set or not, to avoid making the caller set recover just to parse exceptions. If recover is not set, just don't run any queries when generating the parsed exception and return an empty value for the needed information. (A partial parsed exception is better than an unparsed one.)
Aaron Marcuse-Kubitza
03:18 PM Revision 3024: sql_gen.py: is_temp_col(): Use is_table_col() so that the type of the parameter is also checked
Aaron Marcuse-Kubitza
03:15 PM Revision 3023: inputs/import.stats.xls: Bolded the ms/row totals. Added note that non-bolded totals are not directly comparable because different methods were run with different numbers of rows.
Aaron Marcuse-Kubitza
03:10 PM Revision 3022: sql.py: put_table(): Inserting new rows: Removed no longer needed filter-out LEFT JOIN, since the INSERT IGNORE replacement handles duplicate keys
Aaron Marcuse-Kubitza
03:02 PM Revision 3021: sql.py: put_table(): Inserting new rows: Use insert_select()'s (mk_insert_select()'s) new ignore option to ignore duplicate keys
Aaron Marcuse-Kubitza
02:59 PM Revision 3020: sql_gen.py: to_name_only_col(): Consider any non-table column, including NamedCol, to be already name-only. This fixes a bug in sql.mk_insert_select() where the value of a NamedCol was removed by to_name_only_col() even though it was needed.
Aaron Marcuse-Kubitza
02:30 PM Revision 3019: sql.py: mk_insert_select(): INSERT IGNORE: Use an EXCEPTION block for each individual row because "When an error is caught by an EXCEPTION clause, [...] all changes to persistent database state within the block are rolled back." (http://www.postgresql.org/docs/8.3/static/plpgsql-control-structures.html#PLPGSQL-ERROR-TRAPPING). Documented that cursor stays at current position in spite of automatic ROLLBACK on EXCEPTION.
Aaron Marcuse-Kubitza
02:11 PM Revision 3018: sql.py: mk_insert_select(): INSERT IGNORE: Use RETURN QUERY on the insert query instead of RETURN NEXT on a local var to forward the RETURNING value
Aaron Marcuse-Kubitza
02:08 PM Revision 3017: sql.py: mk_insert_select(): INSERT IGNORE: Support RETURNING clause. Always return something to set the correct rowcount.
Aaron Marcuse-Kubitza
02:06 PM Revision 3016: sql_gen.py: Use an as_*() function instead of manually checking the type wherever possible
Aaron Marcuse-Kubitza
01:18 PM Revision 3015: sql.py: mk_insert_select(): INSERT IGNORE: Added duplicate key handling by using EXCEPTION block to catch unique_violation
Aaron Marcuse-Kubitza
12:58 PM Revision 3014: sql.py: mk_insert_select(): INSERT IGNORE: Fixed bug where user-defined types were not supported correctly, by referencing the column's type directly in PL/pgSQL instead of retrieving it from the information_schema. Use a row variable of the output table's row type to store the select query data, so that you don't need to create a separate local var for each output column.
Aaron Marcuse-Kubitza

06/21/2012

10:24 PM Revision 3013: import.stats.xls: Changed \/row (ms)" to "ms/row"
Aaron Marcuse-Kubitza
09:52 PM Revision 3012: sql.py: mk_insert_select(): INSERT IGNORE: Used typed vars to store each column of the select query because the select query's column names are not known, so it would be unknown which record var column to use for each output column. (Add types so there are no unknown-type values that PostgreSQL will say can't be cast.)
Aaron Marcuse-Kubitza
09:21 PM Revision 3011: sql.py: insert_select(): In ignore mode, always recover from errors
Aaron Marcuse-Kubitza
09:14 PM Revision 3010: sql.py: mk_insert_select(): INSERT IGNORE: Implemented simple cursor loop that just inserts each row, without ignoring duplicate keys
Aaron Marcuse-Kubitza
08:26 PM Revision 3009: sql.py: mk_insert_select(): Added ignore param to do an INSERT IGNORE equivalent operation. Added basic structure for INSERT IGNORE. Support embeddable queries without RETURNING columns (which is the case for most INSERT IGNORE queries).
Aaron Marcuse-Kubitza
06:50 PM Revision 3008: sql.py: run_query_into(): Always set into.schema to None, so that table is created in the temp schema in debug_temp mode
Aaron Marcuse-Kubitza
06:25 PM Revision 3007: sql.py: DbConn.DbCursor.execute(): Don't cache ADD COLUMN queries because the rest of the query must be unique in order to use caching
Aaron Marcuse-Kubitza
06:24 PM Revision 3006: sql.py: add_col(): Don't ignore already-existing columns because sometimes name truncation causes collisions, requiring the caller to version the name. add_index_col(): Version the column name to avoid collisions.
Aaron Marcuse-Kubitza
06:08 PM Revision 3005: sql.py: add_index(): Version index names to avoid collisions
Aaron Marcuse-Kubitza
05:58 PM Revision 3004: sql.py: DbConn.DbCursor.execute(): Always cache structural changes, not just if they throw an exception
Aaron Marcuse-Kubitza
05:40 PM Revision 3003: sql.py: add_index(): Fixed bug where expr could not be deep-copied until ensure_not_null() had been run on it, because ensure_not_null() modifies the index_cols of the table and this needs to be modified on the original table
Aaron Marcuse-Kubitza
05:39 PM Revision 3002: sql.py: add_index(): Fixed bug where expr could not be deep-copied until ensure_not_null() had been run on it, because ensure_not_null() modifies the index_cols of the table and this needs to be modified on the original table
Aaron Marcuse-Kubitza
05:12 PM Revision 3001: sql_gen.py: EnsureNotNull: Added to_str() which uses the column's index col if available. This works around a PostgreSQL bug where indexes on expressions are sometimes not used, but indexes on plain columns are used.
Aaron Marcuse-Kubitza
05:09 PM Revision 3000: sql_gen.py: Store index cols in the table instead of in the column, because columns are often recreated from the table and name but tables are generally not copied
Aaron Marcuse-Kubitza
04:21 PM Revision 2999: sql_gen.py: Added is_indexed_col()
Aaron Marcuse-Kubitza
04:15 PM Revision 2998: sql.py: add_index(): Use new sql.ensure_not_null(), which creates a separate column to store the index expr where possible
Aaron Marcuse-Kubitza
04:12 PM Revision 2997: sql.py: Added add_not_null(), add_index_col(), ensure_not_null()
Aaron Marcuse-Kubitza
04:10 PM Revision 2996: sql_gen.py: Added is_temp_col()
Aaron Marcuse-Kubitza
03:57 PM Revision 2995: sql_gen.py: concat(): Also preserve cast suffix
Aaron Marcuse-Kubitza
03:44 PM Revision 2994: sql_gen.py: Col: Added index_col attr
Aaron Marcuse-Kubitza
03:19 PM Revision 2993: sql_gen.py: Added suffixed_col()
Aaron Marcuse-Kubitza
02:59 PM Revision 2992: sql.py: run_query_into(): Set the into table to be a temp table
Aaron Marcuse-Kubitza
02:59 PM Revision 2991: sql_gen.py: Table: Store whether table is temp table
Aaron Marcuse-Kubitza
01:50 PM Revision 2990: sql_gen.py: concat(): Also preserve appended column names
Aaron Marcuse-Kubitza
01:48 PM Revision 2989: sql_gen.py: Col.to_str(): Take for_str param which does both concat() and str()/clean_name() instead of use_concat param which doesn't remove quotes from the strings before concatenating, causing strings to be incorrectly truncated
Aaron Marcuse-Kubitza

06/20/2012

09:46 PM Revision 2988: sql_gen.py: EnsureNotNull: Cast the null sentinel to the type it's the sentinel for, so that COALESCE() returns the same type as the provided type, instead of potentially incorrectly assuming the constant's type. This fixes a bug where COALESCE() returned an incorrect type.
Aaron Marcuse-Kubitza
09:38 PM Revision 2987: sql.py: cast(): Use new sql_gen.Cast
Aaron Marcuse-Kubitza
09:38 PM Revision 2986: sql_gen.py: Added Cast
Aaron Marcuse-Kubitza
09:37 PM Revision 2985: sql_gen.py: concat(): Consider ")"s part of the existing suffix, so that parentheses match up
Aaron Marcuse-Kubitza
09:05 PM Revision 2984: Removed extra trailing whitespace
Aaron Marcuse-Kubitza
08:36 PM Revision 2983: main Makefile: Added explicit schemas/temp/reinstall target because vegbiendev (Ubuntu 12.04) seems to ignore %/reinstall
Aaron Marcuse-Kubitza
08:24 PM Revision 2982: vegbien_dest: Added temp to schemas list so the intermediate tables will be created there, where they are easy to remove with `make schemas/temp/reinstall`
Aaron Marcuse-Kubitza
08:23 PM Revision 2981: main Makefile: Added %/reinstall, which calls the corresponding uninstall and install targets
Aaron Marcuse-Kubitza
08:11 PM Revision 2980: Added temp schema to store intermediate tables permanently when desired for debugging. It is not part of schemas/all because it should not be remade to include current intermediate tables when remaking other schema exports.
Aaron Marcuse-Kubitza
08:04 PM Revision 2979: schemas: Moved *.sql.make into Makefile to take advantage of % pattern matching
Aaron Marcuse-Kubitza
07:47 PM Revision 2978: Removed no longer used schemas/vegbien_empty.sql
Aaron Marcuse-Kubitza
07:46 PM Revision 2977: main Makefile: Removed empty_db, because `make schemas/reinstall` has the same effect and is simpler
Aaron Marcuse-Kubitza
07:40 PM Revision 2976: README.TXT: Changed documentation to use make schemas/reinstall to empty the DB, since that command is simpler. Added how to archive the last import.
Aaron Marcuse-Kubitza
07:11 PM Revision 2975: db_xml.py: put_table(): Removed `if not db.debug_temp` check because that is done by sql.empty_temp()
Aaron Marcuse-Kubitza
07:10 PM Revision 2974: sql.py: put_table(): Use new empty_temp()
Aaron Marcuse-Kubitza
07:06 PM Revision 2973: import.stats.xls: Added comments for estimated numbers. Added "," separators to large numbers.
Aaron Marcuse-Kubitza
06:21 PM Revision 2972: sql.py: empty_temp(): In debug_temp mode, leave temp tables there for debugging
Aaron Marcuse-Kubitza
06:06 PM Revision 2971: sql.py: empty_temp(): Don't output at log_level 2 because it's an internal query, not part of the core algorithm
Aaron Marcuse-Kubitza
06:06 PM Revision 2970: sql.py: truncate(): Added kw_args to pass to run_query()
Aaron Marcuse-Kubitza
05:52 PM Revision 2969: Added inputs/import.stats.xls, which compares row-based and column-based import. This shows that column-based import is slowed down by table locking when run simultaneously, so we will need a new INSERT IGNORE replacement that doesn't lock tables.
Aaron Marcuse-Kubitza
03:14 PM Revision 2968: inputs: Ignore OpenOffice.org lock files
Aaron Marcuse-Kubitza
02:19 PM Revision 2967: sql.py: empty_temp(): Don't print log message if not emptying any tables
Aaron Marcuse-Kubitza
02:16 PM Revision 2966: db_xml.py: put_table(): Empty unneeded temp tables to free up memory
Aaron Marcuse-Kubitza
02:14 PM Revision 2965: sql.py: Added empty_temp()
Aaron Marcuse-Kubitza
02:14 PM Revision 2964: sql.py: Use new lists.mk_seq()
Aaron Marcuse-Kubitza
02:13 PM Revision 2963: lists.py: Added mk_seq()
Aaron Marcuse-Kubitza
02:11 PM Revision 2962: lists.py: is_seq(): Also return true for sets
Aaron Marcuse-Kubitza

06/19/2012

03:02 PM Revision 2961: schemas/vegbien.sql: specimenreplicate: Added indexes using COALESCE() to match what sql_gen does
Aaron Marcuse-Kubitza
02:08 PM Revision 2960: sql.py: put_table(): Getting output table pkeys of existing/inserted rows: Do a DISTINCT ON the input pkey (row_num) in case the plain JOIN matched multiple output table rows for one input table row
Aaron Marcuse-Kubitza
01:44 PM Revision 2959: sql.py: put_table(): Empty unneeded temp tables to free up memory and avoid running out of memory (the temp tables seem to be in-memory only)
Aaron Marcuse-Kubitza
01:30 PM Revision 2958: sql_gen.py: null_sentinels: Added value for type timestamp with time zone. Put each type on its own line for clarity.
Aaron Marcuse-Kubitza
01:03 PM Revision 2957: schemas/vegbien.sql: locationdetermination: Changed indexes to use COALESCE() to match what sql_gen now does
Aaron Marcuse-Kubitza
12:23 PM Revision 2956: schemas/vegbien.sql: location: Added indexes using COALESCE() to match what sql_gen does
Aaron Marcuse-Kubitza
12:06 PM Revision 2955: sql.py: cast_temp_col(): Add an index on the created column
Aaron Marcuse-Kubitza
11:55 AM Revision 2954: sql_gen.py: null_sentinels: Added value for type double precision
Aaron Marcuse-Kubitza
11:52 AM Revision 2953: sql_gen.py: ensure_not_null(): Warn of no null sentinel for type, even if caller catches error
Aaron Marcuse-Kubitza
10:11 AM Revision 2952: schemas/py_functions.sql: Added plain function _namePart() and use it in trigger function _namePart()
Aaron Marcuse-Kubitza
09:42 AM Revision 2951: schemas/py_functions.sql: Added plain functions _dateRangeStart() and _dateRangeEnd() and use them in trigger functions _dateRangeStart() and _dateRangeEnd()
Aaron Marcuse-Kubitza
09:28 AM Revision 2950: schemas/functions.sql: _label(): Ensure that label is NOT NULL so it doesn't NULL out the entire string
Aaron Marcuse-Kubitza
09:23 AM Revision 2949: schemas/functions.sql: Added plain function _nullIf() and use it in trigger function _nullIf()
Aaron Marcuse-Kubitza
08:56 AM Revision 2948: sql.py: DbConn.DbCursor._cache_result(): Corrected comment to reflect why different types of queries are cached differently
Aaron Marcuse-Kubitza
08:46 AM Revision 2947: sql.py: add_col(): Catch DuplicateExceptions so that columns that already existed are ignored
Aaron Marcuse-Kubitza
08:43 AM Revision 2946: sql.py: run_query(): DuplicateException: Also match "column already exists" errors
Aaron Marcuse-Kubitza
08:20 AM Revision 2945: sql.py: Merged DuplicateTableException and DuplicateFunctionException into one exception DuplicateException, with a type variable for the type of duplicate item. Added ExceptionWithNameType.
Aaron Marcuse-Kubitza
08:05 AM Revision 2944: schemas/functions.sql: Fixed bug where external function calls needed to be schema-qualified in case functions schema is not in the search_path
Aaron Marcuse-Kubitza
07:59 AM Revision 2943: schemas/functions.sql: Added plain function _label() and use it in trigger function _label()
Aaron Marcuse-Kubitza
07:50 AM Revision 2942: sql.py: put_table(): Support plain SQL functions in addition to relational functions
Aaron Marcuse-Kubitza

06/18/2012

11:08 PM Revision 2941: sql_gen.py: Added NamedArg. FunctionCall: Support named arguments (http://www.postgresql.org/docs/9.0/static/sql-syntax-calling-funcs.html).
Aaron Marcuse-Kubitza
10:54 PM Revision 2940: schemas/functions.sql: Added plain function _merge() and use it in trigger function _merge()
Aaron Marcuse-Kubitza
10:49 PM Revision 2939: schemas/functions.sql: Added plain function _alt() and use it in trigger function _alt()
Aaron Marcuse-Kubitza
10:37 PM Revision 2938: schemas/functions.sql: Removed no longer used ensure_not_null()
Aaron Marcuse-Kubitza
10:22 PM Revision 2937: sql.py: put_table(): MissingCastException: Use cast_temp_col() so that cast will occur before any main insert, which locks the output table and should take as little time as possible
Aaron Marcuse-Kubitza
10:18 PM Revision 2936: sql.py: Added cast_temp_col()
Aaron Marcuse-Kubitza
10:17 PM Revision 2935: sql.py: add_col(): Support additional run_query() kw_args. add_row_num(): Use new add_col().
Aaron Marcuse-Kubitza
10:09 PM Revision 2934: sql.py: Added add_col()
Aaron Marcuse-Kubitza
08:17 PM Revision 2933: sql_gen.py: Col.__str__(): Truncate any table name using concat() to ensure that the full column name is included in the string
Aaron Marcuse-Kubitza
07:59 PM Revision 2932: strings.py, sql_gen.py: Renamed add_suffix() to concat() to reflect that this is a fixed-length replacement for +
Aaron Marcuse-Kubitza
07:49 PM Revision 2931: sql.py: put_table(): Moved MissingCastException to the top of the exceptions list because it's more of a core exception than the others, and will be raised before any rows are even inserted
Aaron Marcuse-Kubitza
06:20 PM Revision 2930: sql.py: DbConn.with_savepoint(): Always release savepoint, because after ROLLBACK TO SAVEPOINT, "The savepoint remains valid and can be rolled back to again" (http://www.postgresql.org/docs/8.3/static/sql-rollback-to.html). Moved `self._savepoint -= 1` to the main try block's new finally block.
Aaron Marcuse-Kubitza
05:59 PM Revision 2929: sql.py: put_table(): Lock output table right before, and in the same nested transaction as, the insert statement that needs lock, so that it is not released in a prior autocommit and is held for as little time as possible
Aaron Marcuse-Kubitza
05:38 PM Revision 2928: db_xml.py: put_table(): Removed no longer needed commit param
Aaron Marcuse-Kubitza
05:16 PM Revision 2927: bin/map: Removed rollback() call before closing the connection because PostgreSQL does this automatically

05:14 PM Revision 2926: csv2db: Log inserts with log_level=5 so they are not shown for verbosity 4, which is used to see the savepoints and autocommits
Aaron Marcuse-Kubitza
05:13 PM Revision 2925: Removed unnecessary db.db.commit() calls because commits are now done automatically by DbConn's autocommit mode
Aaron Marcuse-Kubitza
04:54 PM Revision 2924: sql.py: DbConn.do_autocommit(): Output the "Autocommitting" debug message with level=4 so that it doesn't clutter up the logging output for normal verbosities
Aaron Marcuse-Kubitza
04:50 PM Revision 2923: DbConn: autocommit mode defaults to True so that all scripts get the benefit of automatic commits
Aaron Marcuse-Kubitza
04:49 PM Revision 2922: input.Makefile: Staging tables: import/install-%: Include the table name in the log file name so that successive tables for the same datasource don't overwrite the same log file
Aaron Marcuse-Kubitza
04:39 PM Revision 2921: sql.py: DbConn: Don't always autocommit in debug_temp mode, because this could cause autocommit mode to be turned on when the user does not expect it
Aaron Marcuse-Kubitza
04:36 PM Revision 2920: bin/map: connect_db(): Autocommit in commit mode to avoid the need for manual commits. This should also reduce the time that table locks are held, to avoid unnecessary contention when multiple processes are trying to insert into the same output table. (The program always uses nested transactions to support rollbacks, so there is no problem autocommitting whenever a top-level nested transaction or top-level query completes.)
Aaron Marcuse-Kubitza
04:29 PM Revision 2919: sql_gen.py: Removed TempFunction because that functionality is now provided by DbConn.TempFunction()
Aaron Marcuse-Kubitza
04:28 PM Revision 2918: sql.py: Use new DbConn.TempFunction()
Aaron Marcuse-Kubitza
04:28 PM Revision 2917: sql.py: DbConn: Added TempFunction()
Aaron Marcuse-Kubitza
04:25 PM Revision 2916: sql.py: Use new DbConn.debug_temp config option to control whether temporary objects should instead be permanent
Aaron Marcuse-Kubitza
04:20 PM Revision 2915: sql.py: DbConn: Added config option debug_temp
Aaron Marcuse-Kubitza
04:12 PM Revision 2914: sql.py: function_exists(): Fixed bug where trigger functions needed to be excluded, since they cannot be called directly
Aaron Marcuse-Kubitza
03:49 PM Revision 2913: sql.py: Added function_exists()
Aaron Marcuse-Kubitza
03:49 PM Revision 2912: sql_gen.py: Made Function an alias of Table so that isinstance(..., Function) will always work correctly
Aaron Marcuse-Kubitza
03:45 PM Revision 2911: sql_gen.py: Added as_Function()
Aaron Marcuse-Kubitza

06/15/2012

06:16 AM Revision 2910: sql.py: put_table(): Lock the output table in EXCLUSIVE mode *before* getting its pkey so that an ACCESS SHARE lock is not acquired before EXCLUSIVE (causing a lock upgrade and deadlock). This race condition may not have been previously noticeable because pkey() is cached, so calling it doesn't necessarily execute a query or acquire an ACCESS SHARE lock.
Aaron Marcuse-Kubitza
05:52 AM Revision 2909: sql.py: put_table(): Document that must be run at the *beginning* of a transaction
Aaron Marcuse-Kubitza
05:49 AM Revision 2908: sql.py: put_table(), mk_select(): Switched back to having put_table() acquire the EXCLUSIVE locks, but right at the beginning of the transaction, in order to avoid lock upgrades which cause deadlocks
Aaron Marcuse-Kubitza
05:35 AM Revision 2907: sql.py: with_autocommit(): Only allow turning autocommit on, because the opposite is not meaningful and may conflict with the session-global isolation level
Aaron Marcuse-Kubitza
05:33 AM Revision 2906: sql.py: DbConn: Set the transaction isolation level to READ COMMITTED using set_isolation_level() so that the isolation level affects all transactions in the session, not just the current one
Aaron Marcuse-Kubitza
05:21 AM Revision 2905: sql.py: DbConn: Always set the transaction isolation level to READ COMMITTED so that when a table is locked for update, its contents are frozen at that point rather than earlier. This ensures that no concurrent duplicate keys were inserted between the time the table was snapshotted (at the beginning of the transaction for SERIALIZABLE) and the time it was locked for update.
Aaron Marcuse-Kubitza
05:02 AM Revision 2904: sql.py: put_table(): Removed locking output tables to prevent concurrent duplicate keys because that is now done automatically by mk_select()
Aaron Marcuse-Kubitza
05:01 AM Revision 2903: sql.py: mk_select(): Filtering on no match: Lock the joined table in EXCLUSIVE mode to prevent concurrent duplicate keys when used with INSERT SELECT
Aaron Marcuse-Kubitza
04:59 AM Revision 2902: sql_gen.py: Added underlying_table() and use it in underlying_col()
Aaron Marcuse-Kubitza
04:39 AM Revision 2901: main Makefile: schemas/rotate: Fixed bug where needed to run schemas/public/install, not full schemas/install, after renaming public schema
Aaron Marcuse-Kubitza
04:32 AM Revision 2900: sql.py: put_table(): Lock output tables to prevent concurrent duplicate keys
Aaron Marcuse-Kubitza
04:31 AM Revision 2899: sql.py: Added lock_table()
Aaron Marcuse-Kubitza
03:53 AM Revision 2898: bin/map: connect_db(): Only use autocommit mode if verbosity > 3, to avoid accidentally activating it if you want debug output in normal import mode
Aaron Marcuse-Kubitza
03:45 AM Revision 2897: bin/map: connect_db(): Only use autocommit mode if verbosity > 2, because it causes the intermediate tables to be created as permanent tables, which you don't want unless you're actually debugging (verbosity = 2 is normal for column-based import)
Aaron Marcuse-Kubitza
03:25 AM Revision 2896: sql.py: put_table(): remove_all_rows(): Changed log message to "Ignoring all rows" because NULL is not necessarily the pkey value that will be returned for the rows
Aaron Marcuse-Kubitza
03:17 AM Revision 2895: sql.py: put_table(): Don't add index on columns that will have values filtered out, because indexes have already been added on all columns in the iteration's input table by flatten()
Aaron Marcuse-Kubitza
03:12 AM Revision 2894: sql.py: DbConn._db(): Setting serializable isolation level: Always set this (if self.serializable is set), even in autocommit mode, because autocommit mode is implemented by manual commits in the DbConn wrapper object rather than using the underlying connection's autocommit mode (which does not allow setting the isolation level)
Aaron Marcuse-Kubitza
03:08 AM Revision 2893: sql.py: DbConn._db(): Setting search_path: Use `SET search_path` and `SHOW search_path` instead of combining the old and new search_paths in SQL itself using `SELECT set_config('search_path', ...)`
Aaron Marcuse-Kubitza
02:47 AM Revision 2892: csv2db: ProgressInputStream: Use default progress message 'Read %d line(s)' because there is not necessarily one CSV row per line, due to embedded newlines
Aaron Marcuse-Kubitza
01:47 AM Revision 2891: input.Makefile: Staging tables: import/install-%: Only output to the log file if log option is non-empty (which it is by default)
Aaron Marcuse-Kubitza
01:46 AM Revision 2890: csv2db: Support reinstalling just the errors table using new errors_table_only option
Aaron Marcuse-Kubitza
01:45 AM Revision 2889: sql.py: Added drop_table()
Aaron Marcuse-Kubitza
01:20 AM Revision 2888: schemas/vegbien.sql: method: Changed indexes to use `COALESCE(..., E'\\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
01:16 AM Revision 2887: schemas/vegbien.sql: specimenreplicate: Added indexes using COALESCE() to match what sql_gen does
Aaron Marcuse-Kubitza
01:12 AM Revision 2886: schemas/vegbien.sql: locationevent: Added indexes using COALESCE() to match what sql_gen does
Aaron Marcuse-Kubitza
12:57 AM Revision 2885: schemas/vegbien.ERD.mwb: Synced with schema
Aaron Marcuse-Kubitza
12:54 AM Revision 2884: schemas/vegbien.sql: party: Changed indexes to use `COALESCE(..., E'\\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
12:38 AM Revision 2883: Wrap sys.stderr.write() calls in strings.to_raw_str() to avoid UnicodeEncodeErrors when stderr is to a file and the default encoding is ASCII
Aaron Marcuse-Kubitza
12:37 AM Revision 2882: strings.py: Added to_raw_str()
Aaron Marcuse-Kubitza
12:12 AM Revision 2881: bin/map: When logging the row # being processed, add 1 because row # is interally 0-based, but 1-based to the user
Aaron Marcuse-Kubitza
12:05 AM Revision 2880: bin/map: Log the row # being processed with level=1.1 so that the user can see a status report if desired
Aaron Marcuse-Kubitza

06/14/2012

11:35 PM Revision 2879: exc.py: str_(): Fixed bug where UnicodeEncodeError would be raised when msg contains non-ASCII chars, by wrapping e.args[0] in strings.ustr()
Aaron Marcuse-Kubitza
11:23 PM Revision 2878: exc.py: print_ex(): Wrap msg in strings.to_unicode() to try to avoid UnicodeEncodeError when msg contains non-ASCII chars
Aaron Marcuse-Kubitza
11:20 PM Revision 2877: sql.py: create_table(): Don't set pkey.nullable to False because the caller should make sure the pkey has the appropriate type
Aaron Marcuse-Kubitza
11:20 PM Revision 2876: csv2db: Use sql_gen.TypedCol.nullable instead of manually adding 'NOT NULL' to the type. Ensure that pkeys are properly NOT NULL.
Aaron Marcuse-Kubitza
11:15 PM Revision 2875: csv2db: Adding indexes: Create plain indexes using ensure_not_null=False because the indexes will primarily be used by the user to search for specific values, rather than by the mapping script which uses the ensure_not_null
Aaron Marcuse-Kubitza
11:13 PM Revision 2874: sql.py: DbConn.col_info(): Run query with log_level=4 because it gathers information about database structure, and should have the same log_level as other queries that do that
Aaron Marcuse-Kubitza
11:09 PM Revision 2873: csv2db: Adding indexes: Fixed bug where col.to_Col() could not be used because sql.add_index() does not support name-only columns (plain strings are OK, though)
Aaron Marcuse-Kubitza
11:00 PM Revision 2872: sql.py: create_table(): has_pkey: Use new TypedCol.constraints to store 'PRIMARY KEY'
Aaron Marcuse-Kubitza
10:59 PM Revision 2871: sql_gen.py: TypedCol: Added constraints instance var
Aaron Marcuse-Kubitza
10:38 PM Revision 2870: sql_gen.py: EnsureNotNull: Made coalesce() all uppercase to match how pg_dump spells it
Aaron Marcuse-Kubitza
10:36 PM Revision 2869: schemas/vegbien.sql: namedplace: Fixed bug where parent_id needed to be included in UNIQUE CONSTRAINT (now UNIQUE INDEX), since there can be more than one e.g. city of the same name if they are in different states
Aaron Marcuse-Kubitza
10:32 PM Revision 2868: schemas/vegbien.sql: plantname: Changed indexes to use `COALESCE(..., 2147483647)` to match what sql_gen now does
Aaron Marcuse-Kubitza
10:22 PM Revision 2867: schemas/py_functions.sql: _dateRangeStart, _dateRangeEnd: Changed indexes to use `COALESCE(..., E'\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
10:19 PM Revision 2866: schemas/py_functions.sql: _namePart: Changed indexes to use `COALESCE(..., E'\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
10:16 PM Revision 2865: schemas/functions.sql: _nullIf: Changed indexes to use `COALESCE(..., E'\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
10:15 PM Revision 2864: schemas/functions.sql: _nullIf: Require a non-NULL null-equivalent value
Aaron Marcuse-Kubitza
10:12 PM Revision 2863: schemas/functions.sql: _label: Changed indexes to use `COALESCE(..., E'\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
10:09 PM Revision 2862: schemas/functions.sql: _label: Require a non-NULL label
Aaron Marcuse-Kubitza
10:04 PM Revision 2861: sql_gen.py: null_sentinels: Removed types where a sentinel doesn't make sense (unknown types, boolean) because types with no sentinel are now handled gracefully by users of ensure_not_null()
Aaron Marcuse-Kubitza
10:00 PM Revision 2860: sql.py: add_index(): ensure_not_null: Handle unknown types gracefully
Aaron Marcuse-Kubitza
09:52 PM Revision 2859: sql_gen.py: MockDb: Added col_info()
Aaron Marcuse-Kubitza
09:48 PM Revision 2858: sql_gen.py: Use as_*() functions where the auto-wrapping was previously done manually
Aaron Marcuse-Kubitza
09:44 PM Revision 2857: sql_gen.py: CompareCond.to_str(): Use ensure_not_null()'s new type_ param to apply same function to both sides but not if the right side is already NOT NULL
Aaron Marcuse-Kubitza
09:26 PM Revision 2856: sql_gen.py: null_sentinels: Added value for character varying type
Aaron Marcuse-Kubitza
08:45 PM Revision 2855: sql_gen.py: ensure_not_null(): Support non-column inputs if type_ is set
Aaron Marcuse-Kubitza
08:32 PM Revision 2854: sql_gen.py: null_sentinels: Added value for USER-DEFINED type
Aaron Marcuse-Kubitza
08:31 PM Revision 2853: sql.py: mk_select(): Joins: Filtering on no match: Use '~=' sql_gen.CompareCond operator so that IS NULL is always used, regardless of the not-null column's nullability
Aaron Marcuse-Kubitza
08:24 PM Revision 2852: sql_gen.py: null_sentinels: Added value for boolean type
Aaron Marcuse-Kubitza
08:21 PM Revision 2851: sql_gen.py: ensure_not_null(): Added type_ param to override the underlying column's type
Aaron Marcuse-Kubitza
08:09 PM Revision 2850: sql_gen.py: EnsureNotNull: Take a type param instead of a null param so that the EnsureNotNull object stores the underlying column's type
Aaron Marcuse-Kubitza
08:00 PM Revision 2849: sql_gen.py: underlying_col(): Support non-Col inputs
Aaron Marcuse-Kubitza
07:42 PM Revision 2848: sql_gen.py: EnsureNotNull: Removed default value for null param to remind user that default value depends on value's type and will not always be a string
Aaron Marcuse-Kubitza
07:39 PM Revision 2847: sql.py: add_index(): Added ensure_not_null param to disable the ensure_not_null functionality to force a plain index
Aaron Marcuse-Kubitza
07:14 PM Revision 2846: sql.py: flatten(): Add indexes on the created table so its columns can be used in an O(n) merge join
Aaron Marcuse-Kubitza
07:12 PM Revision 2845: sql_gen.py: null_sentinels: Added value for integer type
Aaron Marcuse-Kubitza
06:52 PM Revision 2844: sql_gen.py: CompareCond.to_str(): Always wrap the left-side column if it's nullable. Wrap the right-side value if the left side was wrapped, rather than if both the left and right side are nullable. This causes coalesce() indexes to be used to look up NULL values using the value NULL gets coalesced to, rather than doing a sequential scan.
Aaron Marcuse-Kubitza
06:43 PM Revision 2843: sql_gen.py: Run truncate() on all identifiers so that literal-string-based lookups for an identifier (such as in db.col_info()) don't use the untruncated value
Aaron Marcuse-Kubitza
06:40 PM Revision 2842: sql_gen.py: Added truncate()
Aaron Marcuse-Kubitza
06:40 PM Revision 2841: sql.py: put_table(): Resolving default value column: Fixed bug where default value of None was used as a key for mapping, even though this is an invalid Col name
Aaron Marcuse-Kubitza
05:30 PM Revision 2840: sql_gen.py: ensure_not_null(): If input column cannot be ensured to be NULL, pass any raised exception through rather than suppressing it and leaving the column in a nullable state
Aaron Marcuse-Kubitza

06/13/2012

11:11 PM Revision 2839: schemas/functions.sql: _merge: Changed indexes to use `COALESCE(..., E'\\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
11:08 PM Revision 2838: schemas/functions.sql: _alt: Changed indexes to use `COALESCE(..., E'\\N')` to match what sql_gen now does
Aaron Marcuse-Kubitza
10:59 PM Revision 2837: sql_gen.py: CompareCond.to_str(): Handle nullable columns using ensure_not_null()
Aaron Marcuse-Kubitza
10:46 PM Revision 2836: sql_gen.py: ensure_not_null(): Raise NoUnderlyingTableException if can't ensure not null for that reason
Aaron Marcuse-Kubitza
10:20 PM Revision 2835: sql_gen.py: is_underlying_table(): Support non-Table inputs
Aaron Marcuse-Kubitza
10:15 PM Revision 2834: sql_gen.py: NamedValues: Call set_cols_table() with the created table, not just the name, so that is_underlying_table() works properly
Aaron Marcuse-Kubitza
09:49 PM Revision 2833: sql_gen.py: underlying_col(): If no underlying table, raise NoUnderlyingTableException
Aaron Marcuse-Kubitza
09:45 PM Revision 2832: sql_gen.py: Added is_underlying_table()
Aaron Marcuse-Kubitza
09:34 PM Revision 2831: sql_gen.py: ensure_not_null(): Call underlying_col() on the column to remove all renamings
Aaron Marcuse-Kubitza
09:33 PM Revision 2830: sql_gen.py: Added underlying_col()
Aaron Marcuse-Kubitza
09:24 PM Revision 2829: sql_gen.py: Join.to_str(): join(): Removed no longer needed `*_table = *_table.to_Table()`
Aaron Marcuse-Kubitza
09:22 PM Revision 2828: sql_gen.py: Col: Support Table objects that are not just names, by calling `.to_Table()` on the table before stringifying it
Aaron Marcuse-Kubitza
09:22 PM Revision 2827: sql_gen.py: Col: Support Table objects that are not just names, by calling `.to_Table()` on the table before stringifying it
Aaron Marcuse-Kubitza
08:59 PM Revision 2826: sql_gen.py: ensure_not_null(): Added ignore_unknown_type param
Aaron Marcuse-Kubitza
08:55 PM Revision 2825: sql_gen.py: CompareCond.to_str(): Put handling nullable columns as a separate step so it can be expanded
Aaron Marcuse-Kubitza
08:36 PM Revision 2824: csv2db: Errors table: Removed no longer needed sql_gen.EnsureNotNull() because this is now added automatically
Aaron Marcuse-Kubitza
08:35 PM Revision 2823: sql.py: add_index(): Handle nullable columns by using sql_gen.ensure_not_null() to automatically add a coalesce() wrapper where needed
Aaron Marcuse-Kubitza
08:33 PM Revision 2822: sql_gen.py: Added ensure_not_null()
Aaron Marcuse-Kubitza
08:29 PM Revision 2821: sql.py: DbConn.col_info(): Fixed bug where is_nullable needed to be cast to a boolean
Aaron Marcuse-Kubitza
08:06 PM Revision 2820: sql.py: cast(): Support string column name inputs
Aaron Marcuse-Kubitza
07:12 PM Revision 2819: sql.py: DbConn: Renamed col_default() to col_info() and have it return a sql_gen.TypedCol object containing all the TypedCol info about the column, not just the default value
Aaron Marcuse-Kubitza
06:55 PM Revision 2818: sql_gen.py: TypedCol: Added default and nullable params
Aaron Marcuse-Kubitza
06:53 PM Revision 2817: dicts.py: Import util after items that util depends on have been defined, to avoid unsatisfied circular dependency
Aaron Marcuse-Kubitza
06:30 PM Revision 2816: sql.py: DbConn.col_default(): Pass the connection to sql_gen.as_Code() so it fixes the syntax on values returned by PostgreSQL
Aaron Marcuse-Kubitza
06:29 PM Revision 2815: sql_gen.py: as_Code(): Added optional db param, which causes the function to run db.std_code() on the value to fix the syntax
Aaron Marcuse-Kubitza
06:27 PM Revision 2814: sql.py: DbConn: Added std_code()
Aaron Marcuse-Kubitza
03:02 PM Revision 2813: db_xml.py: Removed into_table_name() because this functionality is now handled by sql.into_table_name()
Aaron Marcuse-Kubitza
02:59 PM Revision 2812: sql.py: into_table_name(): Also parse hierarchical tables (mappings with a rank column) using a special syntax
Aaron Marcuse-Kubitza
02:44 PM Revision 2811: sql.py: put_table(): Fixed bug where distinct_on included columns that were not in the input table, and were thus incorrectly taken from the LEFT JOINed output table
Aaron Marcuse-Kubitza

06/12/2012

10:32 PM Revision 2810: sql.py: track_data_error(): Do nothing if cols are empty, because mk_track_data_error() requires at least one col. mk_track_data_error(): Assert that cols are not empty because VALUES clause requires at least one row.
Aaron Marcuse-Kubitza
10:26 PM Revision 2809: bin/map: by_col: Pass on_error to db_xml.put_table() that calls ex_tracker.track()
Aaron Marcuse-Kubitza
10:14 PM Revision 2808: sql.py: put_table(): No handler for exception: Pass exception to on_error() instead of raising a warning, so that error message can be formatted
Aaron Marcuse-Kubitza
10:08 PM Revision 2807: db_xml.py: put_table(): Pass on_error to sql.put_table()
Aaron Marcuse-Kubitza
10:07 PM Revision 2806: db_xml.py: put_table(): Take on_error param like row-based put()
Aaron Marcuse-Kubitza
10:06 PM Revision 2805: sql.py: put_table(): Take on_error param
Aaron Marcuse-Kubitza
09:48 PM Revision 2804: sql.py: get_cur_query(): Removed no longer used input_params parameter
Aaron Marcuse-Kubitza
09:46 PM Revision 2803: sql.py: Removed unused mogrify()
Aaron Marcuse-Kubitza
09:42 PM Revision 2802: sql.py: DbConn.DbCursor.execute(): Removed no longer used params parameter
Aaron Marcuse-Kubitza
09:32 PM Revision 2801: sql.py: with_autocommit(): Use isolation_level attr and set_isolation_level() method of connection instead of autocommit attr to support older versions of psycopg2
Aaron Marcuse-Kubitza
09:18 PM Revision 2800: sql.py: DbConn.DbCursor.execute(): Only fetch all rows for empty SELECT query, to support older versions of Python that would give a "no results to fetch" error for other types of queries
Aaron Marcuse-Kubitza
09:13 PM Revision 2799: csv2db: When reraising exception, use `raise` instead of `raise e` to preserve whole stack trace
Aaron Marcuse-Kubitza
09:12 PM Revision 2798: sql.py: Removed no longer used _query_lookup()
Aaron Marcuse-Kubitza
09:05 PM Revision 2797: sql.py: DbConn: Cache queries without params, as params are no longer used
Aaron Marcuse-Kubitza
09:03 PM Revision 2796: sql.py: DbConn.is_cached(): Removed no longer used params parameter
Aaron Marcuse-Kubitza
09:01 PM Revision 2795: sql.py: Removed no longer used run_raw_query()
Aaron Marcuse-Kubitza
09:00 PM Revision 2794: sql.py: run_query(): Call db.run_query() directly instead of via run_raw_query()
Aaron Marcuse-Kubitza
08:56 PM Revision 2793: sql.py: DbConn.run_query(): Removed no longer used params parameter
Aaron Marcuse-Kubitza
08:50 PM Revision 2792: sql.py: DbConn._db(): Setting search_path: Use esc_value() instead of params
Aaron Marcuse-Kubitza
08:43 PM Revision 2791: sql.py: run_query(): Removed no longer used params parameter
Aaron Marcuse-Kubitza
08:37 PM Revision 2790: sql.py: run_query_into(): Moved main case (into != None) outside of if statement because the special-case if statement contains `return`
Aaron Marcuse-Kubitza
08:35 PM Revision 2789: sql.py: run_query_into(): Removed no longer used params parameter
Aaron Marcuse-Kubitza
08:32 PM Revision 2788: sql.py: mk_insert_select(): Removed no longer used params parameter
Aaron Marcuse-Kubitza
08:25 PM Revision 2787: sql.py: mk_insert_select(): Return just the query instead of the query plus empty params
Aaron Marcuse-Kubitza
08:22 PM Revision 2786: sql.py: mk_select(): Return just the query instead of the query plus empty params
Aaron Marcuse-Kubitza
08:12 PM Revision 2785: sql.py: tables(): Use select() instead of a custom run_query() to avoid using params, which will be deprecated to make it easier to support old versions of Python
Aaron Marcuse-Kubitza
08:11 PM Revision 2784: sql.py: DbConn.DbCursor.execute(): Require that params are empty, to ensure that code uses db.esc_value() instead. This keeps literal values in the same place as the rest of the query, so that they do not need to be maintained and passed around separately in a params list.
Aaron Marcuse-Kubitza
08:06 PM Revision 2783: sql.py: constraint_cols(): Use db.esc_value() instead of params
Aaron Marcuse-Kubitza

Aaron Marcuse-Kubitza
07:03 PM Revision 2777: sql.py: truncate(): Re-added support for string tables using sql_gen.as_Table(). This fixes empty_db(), which relied on this functionality.
Aaron Marcuse-Kubitza
07:01 PM Revision 2776: sql_gen.py: as_Table(): Added schema param to use as default schema
Aaron Marcuse-Kubitza
06:54 PM Revision 2775: inputs/SALVIAS: Switched to using CSV exports of the DB, so that staging tables could be created for column-based import
Aaron Marcuse-Kubitza
06:48 PM Revision 2774: sql.py: run_query_into(): Added add_indexes_ param which causes the function to add indexes on the created table
Aaron Marcuse-Kubitza
06:18 PM Revision 2773: sql.py: create_table(): Use new add_indexes()
Aaron Marcuse-Kubitza
06:15 PM Revision 2772: sql.py: Added add_indexes()
Aaron Marcuse-Kubitza
05:38 PM Revision 2771: sql.py: get_cur_query(): Fixed bug where strings.ustr() needed to be used instead of str() when ensuring that get_cur_query() returns a string
Aaron Marcuse-Kubitza
05:35 PM Revision 2770: sql.py: cast(): Removed conditional checks for save_errors, since it's now always true if the function got passed the `not save_errors` special case
Aaron Marcuse-Kubitza
05:32 PM Revision 2769: sql.py: cast(): Only convert errors to warnings if errors will be saved in errors_table, so that import will always be aborted if user supplied invalid values in the mappings, even if these values are passed through a relational function
Aaron Marcuse-Kubitza
04:58 PM Revision 2768: sql.py: put_table(): Support inserting tables with all default values, by providing the pkey's default value for all rows so that the SELECT query has at least one column
Aaron Marcuse-Kubitza
04:57 PM Revision 2767: sql_gen.py: is_table_col(): Check that input is a Col object
Aaron Marcuse-Kubitza
04:31 PM Revision 2766: sql.py: put_table(): Assert that mapping is non-empty
Aaron Marcuse-Kubitza
04:23 PM Revision 2765: sql.py: mk_select(): Assert that fields list is non-empty
Aaron Marcuse-Kubitza
04:18 PM Revision 2764: sql.py: DbConn.DbCursor.execute(): Set _is_insert only if query *starts with* INSERT, so that function definitions containing INSERT are not cached as INSERT statements (exceptions only) themselves
Aaron Marcuse-Kubitza
04:10 PM Revision 2763: sql.py: DbConn.DbCursor.execute(): Fixed bug where params == None would apparently turn off the mogrifier completely, causing "%"s to be excessively escaped, by just setting params to None if it was [] or () and not using strings.esc_for_mogrify() at all
Aaron Marcuse-Kubitza
03:51 PM Revision 2762: sql.py: DbConn.DbCursor.execute(): If not using params, escape the query using strings.esc_for_mogrify() in case any literals contained "%"s
Aaron Marcuse-Kubitza
03:49 PM Revision 2761: strings.py: Added esc_for_mogrify()
Aaron Marcuse-Kubitza
03:05 PM Revision 2760: sql.py: create_table(): Add indexes on all non-pkey columns, unless turned off or deferred using new param col_indexes
Aaron Marcuse-Kubitza
02:46 PM Revision 2759: csv2db: Add column indexes on errors table. Use typed_cols and `.to_Col()` to iterate over columns to add indexes on, for the main and errors tables.
Aaron Marcuse-Kubitza

06/11/2012

11:13 PM Revision 2758: sql.py: Added track_data_error(). put_table(): ignore(): Take extra e param for the exception. Use track_data_error() to store the invalid value in the errors table.
Aaron Marcuse-Kubitza
11:11 PM Revision 2757: sql_gen.py: Join.to_str(): Add newline before and after right table if it's been renamed (and therefore takes up multiple lines)
Aaron Marcuse-Kubitza
11:10 PM Revision 2756: exc.py: ExceptionWithCause: Store the cause in an instance variable for later use
Aaron Marcuse-Kubitza
10:47 PM Revision 2755: sql.py: mk_track_data_error(): Rename the errors_table to make the generated SQL less verbose
Aaron Marcuse-Kubitza
10:42 PM Revision 2754: sql.py: mk_insert_select(): Run sql_gen.remove_table_rename() on table to get just the actual name in the DB
Aaron Marcuse-Kubitza
10:42 PM Revision 2753: sql_gen.py: Added remove_table_rename()
Aaron Marcuse-Kubitza
10:40 PM Revision 2752: sql_gen.py: Col: Run `.to_Table()` on table to get just the reference to the table, not any SQL code that defines it
Aaron Marcuse-Kubitza
10:10 PM Revision 2751: sql.py: Added mk_track_data_error() and use it in cast(). This also ensures that if only one source column's row in the CROSS JOIN violates a unique constraint, other source columns' rows are still inserted.
Aaron Marcuse-Kubitza
09:59 PM Revision 2750: sql_gen.py: with_default_table(): Added overwrite param to overwrite the table (if it isn't a NamedCol)
Aaron Marcuse-Kubitza
09:57 PM Revision 2749: sql_gen.py: Join.to_str(): join(): Get just the table name of left_table and right_table using `.to_Table()`. Moved order switching of tables inside join() because the order reversing only applies to an individual condition.
Aaron Marcuse-Kubitza
09:34 PM Revision 2748: sql_gen.py: Renamed set_default_table() to with_default_table() and copy col before modifying it so don't modify input
Aaron Marcuse-Kubitza
09:14 PM Revision 2747: sql_gen.py: Added set_default_table(). as_ValueCond(): Use set_default_table() instead of as_Col() so that any name-only column also gets its table set. Join.to_str(): Parse left side using set_default_table() instead of as_Col() so that any name-only column also gets its table set.
Aaron Marcuse-Kubitza
07:31 PM Revision 2746: sql_gen.py: Join: mapping param defaults to {} for e.g. CROSS JOINs. to_str(): Omit join_cond if mapping is empty, rather than if join is a specific type.
Aaron Marcuse-Kubitza
07:24 PM Revision 2745: sql_gen.py: NamedValues: Change cols to Col objects with the table set to `name`
Aaron Marcuse-Kubitza
07:23 PM Revision 2744: sql_gen.py: Added set_cols_table()
Aaron Marcuse-Kubitza
07:00 PM Revision 2743: sql.py: mk_insert_select(): returning: Use sql_gen.to_name_only_col()
Aaron Marcuse-Kubitza
06:52 PM Revision 2742: sql_gen.py: NamedTable: cols: Use sql_gen.Col objects or name strings instead of pre-rendered SQL code
Aaron Marcuse-Kubitza
06:35 PM Revision 2741: sql_gen.py: NamedTable: Wrap nested code in Expr if needed
Aaron Marcuse-Kubitza
06:27 PM Revision 2740: sql_gen.py: Added NamedValues
Aaron Marcuse-Kubitza
06:04 PM Revision 2739: sql_gen.py: Values: Support multiple rows
Aaron Marcuse-Kubitza
05:54 PM Revision 2738: sql.py: insert(): Use new sql_gen.Values
Aaron Marcuse-Kubitza
05:53 PM Revision 2737: sql_gen.py: Added Values and default
Aaron Marcuse-Kubitza
05:26 PM Revision 2736: sql_gen.py: Join.to_str(): Don't add join condition for CROSS JOINs
Aaron Marcuse-Kubitza
05:03 PM Revision 2735: sql.py: put_table(): Factored out errors_table name setting so it can be used by ignore()
Aaron Marcuse-Kubitza
04:38 PM Revision 2734: bin/map: If doing full import, clear errors table
Aaron Marcuse-Kubitza
04:37 PM Revision 2733: sql.py: truncate(): Support sql_gen.Table objects
Aaron Marcuse-Kubitza
04:21 PM Revision 2732: sql.py: Moved truncate() to Database structure queries section
Aaron Marcuse-Kubitza
04:11 PM Revision 2731: sql.py: tables(): Run query with log_level=4 because it's a low-level structure-determining query
Aaron Marcuse-Kubitza
04:07 PM Revision 2730: sql.py: table_exists(): Use new tables() exact param so that LIKE special chars in table name are not interpreted specially
Aaron Marcuse-Kubitza
04:07 PM Revision 2729: sql.py: tables(): Added exact param to check for exact matches only
Aaron Marcuse-Kubitza
04:03 PM Revision 2728: sql.py: put_table(): MissingCastException: Use new errors_table()
Aaron Marcuse-Kubitza
04:02 PM Revision 2727: csv2db: Use new sql.errors_table()
Aaron Marcuse-Kubitza
04:02 PM Revision 2726: sql.py: Added table_exists() and errors_table()
Aaron Marcuse-Kubitza

06/08/2012

09:59 PM Revision 2725: sql.py: DbConn.print_notices(): Fixed bug where it should not do anything for a MySQL connection, because that doesn't store notices the way Postgres does
Aaron Marcuse-Kubitza
09:54 PM Revision 2724: sql.py: put_table(): MissingCastException: Debug message: Added Redmine formatting
Aaron Marcuse-Kubitza
09:48 PM Revision 2723: schemas/functions.sql, vegbien.sql: Removed no longer needed cast functions, which are now created on the fly by column-based import
Aaron Marcuse-Kubitza
09:45 PM Revision 2722: schemas/functions.sql: _nullIf(): Ignore uncastable value, because a value that's invalid for the given type is still well-defined as not matching the nullif() criterion
Aaron Marcuse-Kubitza
09:25 PM Revision 2721: sql.py: put_table(): MissingCastException: Debug message: Removed "'s" so it wouldn't mess up syntax highlighting when pasting debug output into a SQL file
Aaron Marcuse-Kubitza
09:08 PM Revision 2720: sql.py: cast(): Made errors table also store SQLSTATE in error_code column
Aaron Marcuse-Kubitza
08:40 PM Revision 2719: sql.py: cast(): Documented that the value and error are inserted for *each* source column (hence the CROSS JOIN)
Aaron Marcuse-Kubitza
08:39 PM Revision 2718: sql.py: cast(): Version the function name if using an errors table, to avoid collisions with other cast functions when the function name is truncated (or, more rarely, collisions with casts to the same type and on the same input columns but of a different table)
Aaron Marcuse-Kubitza
08:25 PM Revision 2717: sql.py: cast(): function_name: Fixed bug where sql_gen.FunctionCall()'s parameters needed to be passed with *args syntax
Aaron Marcuse-Kubitza
08:23 PM Revision 2716: sql.py: mk_flatten_mapping(): Propagate the original columns' sources to the flattened columns so they won't be lost in the flattening
Aaron Marcuse-Kubitza
08:20 PM Revision 2715: sql.py: put_table(): MissingCastException: Use in_tables0's source table to locate the errors table in case in_tables0 has been subset into a temp table (which removes the schema name)
Aaron Marcuse-Kubitza
08:19 PM Revision 2714: db_xml.py: put_table(): Track in_table's source so its original schema can be obtained and auxiliary tables located
Aaron Marcuse-Kubitza
08:17 PM Revision 2713: sql_gen.py: Derived.set_srcs(): Added optional overwrite param so that a default srcs value can be set only if one isn't already set
Aaron Marcuse-Kubitza
08:04 PM Revision 2712: sql_gen.py: Made Table a Derived element so that a row-subset temp table could retain the schema of the table it came from, and any auxiliary tables in that schema could be located properly
Aaron Marcuse-Kubitza
08:01 PM Revision 2711: sql_gen.py: Moved srcs-related functionality from Col to new superclass Derived
Aaron Marcuse-Kubitza
07:53 PM Revision 2710: sql.py: cast(): save_errors: Fixed bug where srcs needed to have their names extracted before being wrapped in sql_gen.Literals. Fixed bug where errors table INSERT needed to prefix the CROSS JOIN-ed VALUES statements with SELECT * FROM because the CROSS JOIN makes it a whole SELECT query, not just a VALUES statement.
Aaron Marcuse-Kubitza
07:40 PM Revision 2709: schemas/vegbien.ERD.mwb: Adjusted lines to make less intersections happen on the first page
Aaron Marcuse-Kubitza
07:27 PM Revision 2708: sql.py: put_table(): MissingCastException: Fixed bug where errors_table needed to have the same schema as in_tables0 as well as part of the same name
Aaron Marcuse-Kubitza
07:23 PM Revision 2707: sql_gen.py: Added suffixed_table()
Aaron Marcuse-Kubitza
07:14 PM Revision 2706: sql.py: MissingCastException: Print log message that it's casting the column, to introduce the SQL function definition that follows
Aaron Marcuse-Kubitza
07:06 PM Revision 2705: sql.py: put_table(): MissingCastException: Use new cast() instead of relying on existing cast functions in the database
Aaron Marcuse-Kubitza
07:04 PM Revision 2704: sql.py: Added cast()
Aaron Marcuse-Kubitza
06:00 PM Revision 2703: sql_gen.py: Added wrap() and use it in wrap_in_func()
Aaron Marcuse-Kubitza
05:36 PM Revision 2702: sql.py: put_table(): Track the input column(s) a column is derived from, so that error messages can be attributes to the proper input column(s)
Aaron Marcuse-Kubitza
05:35 PM Revision 2701: sql_gen.py: Col: Support tracking the column(s) a column is derived from, so that error messages can be attributes to the proper input column(s)
Aaron Marcuse-Kubitza
05:33 PM Revision 2700: objects.py: BasicObject: Allow subclasses to customize which attrs are compared on, by adding _compare_on() method
Aaron Marcuse-Kubitza
04:45 PM Revision 2699: lists.py: uniqify(): Document that it will work on any iterable, not just lists
Aaron Marcuse-Kubitza
04:06 PM Revision 2698: sql.py: mk_insert_select(): embeddable: Use sql_gen.TempFunction and sql_gen.FunctionCall
Aaron Marcuse-Kubitza
04:04 PM Revision 2697: sql_gen.py: Added TempFunction
Aaron Marcuse-Kubitza
03:26 PM Revision 2696: schemas/functions.sql, vegbien.sql: Cast functions: Removed `RETURN new;` at end (artifact of when they were relational functions). Made the EXCEPTION block the main block of the function, to avoid unnecessary nesting.
Aaron Marcuse-Kubitza
02:26 PM Revision 2695: csv2db: Errors table: index_cols: Remove no longer needed sql_gen.Col() (now done by EnsureNotNull)
Aaron Marcuse-Kubitza
02:25 PM Revision 2694: sql_gen.py: EnsureNotNull: Run value through as_Col() so FunctionCall won't default it to a Literal
Aaron Marcuse-Kubitza
02:19 PM Revision 2693: csv2db: Use sql_gen.EnsureNotNull instead of the ensure_not_null() function in the functions schema to avoid a dependency on the functions schema, which would cause the UNIQUE index to be dropped whenever the functions schema is reinstalled
Aaron Marcuse-Kubitza
02:18 PM Revision 2692: sql_gen.py: Added EnsureNotNull
Aaron Marcuse-Kubitza
02:17 PM Revision 2691: sql_gen.py: Added InternalFunction
Aaron Marcuse-Kubitza
02:08 PM Revision 2690: sql_gen.py: FunctionCall: Ensure all args are Code objects using as_Value()
Aaron Marcuse-Kubitza
01:51 PM Revision 2689: csv2db: Errors table: Add UNIQUE index on all columns
Aaron Marcuse-Kubitza
01:50 PM Revision 2688: sql.py: add_index(): Support multiple column(s) or expression(s). Support separate table (not extracted from cols). Support UNIQUE indexes.
Aaron Marcuse-Kubitza

06/07/2012

09:41 PM Revision 2687: sql.py: add_index(): Fixed bug where expr needed to be deep copied so that any column nested in it (e.g. inside a FunctionCall) wouldn't be modified when col.table is set to None
Aaron Marcuse-Kubitza
09:35 PM Revision 2686: sql.py: add_pkey(): Support multiple, custom columns
Aaron Marcuse-Kubitza
09:24 PM Revision 2685: csv2db: Vacuum the created table
Aaron Marcuse-Kubitza
09:23 PM Revision 2684: sql.py: Added vacuum()
Aaron Marcuse-Kubitza
09:23 PM Revision 2683: sql.py: DbConn: Added with_autocommit()
Aaron Marcuse-Kubitza
08:58 PM Revision 2682: csv2db: Create errors table for use by column-based import
Aaron Marcuse-Kubitza
08:57 PM Revision 2681: sql.py: create_table(): Added has_pkey param to disable making the first column the primary key
Aaron Marcuse-Kubitza
08:21 PM Revision 2680: csv2db: Use verbosity-based logging like bin/map. Use sql.create_table(). Add indexes on the columns to speed up column-based import and to speed up searching the table for particular values.
Aaron Marcuse-Kubitza
08:00 PM Revision 2679: sql.py: create_table(): Don't add indexes on columns, because that shouldn't happen until after the table's rows have been inserted
Aaron Marcuse-Kubitza
07:55 PM Revision 2678: sql.py: DbConn._db(): Output 'SET TRANSACTION ISOLATION LEVEL SERIALIZABLE' with log_level=4 because that should not be shown when the search_path is shown, which has log_level=3
Aaron Marcuse-Kubitza
07:43 PM Revision 2677: sql.py: cleanup_table(): Use update(), which also fixes some formatting bugs
Aaron Marcuse-Kubitza
07:24 PM Revision 2676: sql.py: DbConn._db(): Output connection configuration statements with log_level=3
Aaron Marcuse-Kubitza
07:15 PM Revision 2675: sql.py: Added create_table()
Aaron Marcuse-Kubitza
07:14 PM Revision 2674: sql_gen.py: Added TypedCol
Aaron Marcuse-Kubitza
06:59 PM Revision 2673: sql.py: insert_select(): Pass log_level to run_query_into()
Aaron Marcuse-Kubitza
05:15 PM Revision 2672: streams.py: LineCountInputStream: Fixed bug where EOF was incorrectly considered a line, causing the final line count (used by ProgressInputStream) to be off by one
Aaron Marcuse-Kubitza
04:25 PM Revision 2671: sql.py: DbConn: Added print_notices() and call it after running a query
Aaron Marcuse-Kubitza
04:12 PM Revision 2670: dicts.py: Added IdCompared
Aaron Marcuse-Kubitza
03:50 PM Revision 2669: lists.py: Added clear()
Aaron Marcuse-Kubitza
03:24 PM Revision 2668: sql.py: DbConn.do_autocommit(): Fixed typo in 'Autocommiting' debug message
Aaron Marcuse-Kubitza
03:20 PM Revision 2667: sql_gen.py: ColDict: Extend dicts.DictProxy instead of UserDict.DictMixin because that already provides some of the functionality needed by ColDict
Aaron Marcuse-Kubitza

06/06/2012

09:46 PM Revision 2666: sql.py: run_query(): Only pass non-None debug_msg_ref to DbConn.run_query() if filtering with log_ignore_excs or can't mogrify() (and therefore can't print queries before they're run)
Aaron Marcuse-Kubitza
09:36 PM Revision 2665: sql.py: DbConn: Added can_mogrify() and use it in mogrify()
Aaron Marcuse-Kubitza
09:35 PM Revision 2664: sql.py: DbConn.run_query(): Log query before running if no debug_msg_ref specified. Documented debug_msg_ref param.
Aaron Marcuse-Kubitza
08:43 PM Revision 2663: sql.py: DbConn: Added mogrify() and use it in esc_value()
Aaron Marcuse-Kubitza
07:58 PM Revision 2662: schemas/functions.sql: _nullIf(): Fixed bug where wrong var name was used to retrieve type param. Reenabled _nullIf now that it's working.
Aaron Marcuse-Kubitza
07:25 PM Revision 2661: sql_gen.py: ColDict.__setitem__(): Translate NULL values to the appropriate default value of the key column (which is often NULL, but not always) so that select query filtering/joins work correctly
Aaron Marcuse-Kubitza
07:21 PM Revision 2660: sql.py: DbConn.col_default(): Fixed bug where returned string needed to be wrapped in sql_gen.as_Code() because it's sometimes a SQL expression and sometimes NULL
Aaron Marcuse-Kubitza
07:20 PM Revision 2659: sql_gen.py: Added as_Code(). Split SQL code objects into separate sections so unparameterized classes would be separate from general classes.
Aaron Marcuse-Kubitza
07:08 PM Revision 2658: sql_gen.py: Code.to_str(): Fixed bug where needed to raise NotImplementedError, not NotImplemented
Aaron Marcuse-Kubitza
06:58 PM Revision 2657: dicts.py: is_dict(): Fixed bug where lists also have __getitem__() methods, so keys() was checked for instead
Aaron Marcuse-Kubitza
06:44 PM Revision 2656: sql.py: put_table(): Fixed bug where mapping was still a plain dict because that's what dicts.join() returns, by moving the wrapping of it in a sql_gen.ColDict after dicts.join()
Aaron Marcuse-Kubitza
06:28 PM Revision 2655: sql_gen.py: ColDict: Fixed bug where copy() needed to be implemented
Aaron Marcuse-Kubitza
06:14 PM Revision 2654: sql.py: into_table_name(): Fixed bug where key needed to be passed through str() now that ColDict uses Col objects for everything
Aaron Marcuse-Kubitza
06:11 PM Revision 2653: sql_gen.py: ColDict: Extend UserDict.DictMixin instead of dict because its non-core function implementations route all inner dict accesses to the core functions __getitem__() and __setitem__(). sql.py: put(): DuplicateKeyException: Wrap util.dict_subset_right_join() in a sql_gen.ColDict because the dict returned by util.dict_subset_right_join() is just a plain dict. (This change must happen at the same time because the previous functionality relied on a bug in ColDict.)
Aaron Marcuse-Kubitza
06:04 PM Revision 2652: util.py: DefaultDict: Use dicts.DictProxy instead of collections.defaultdict so that it provides a view of the given dict instead of copying it
Aaron Marcuse-Kubitza
06:03 PM Revision 2651: dicts.py: Added DictProxy
Aaron Marcuse-Kubitza
05:37 PM Revision 2650: sql.py: mk_select(): conds: Support dict-like objects other than dict itself (such as sql_gen.ColDict)
Aaron Marcuse-Kubitza
05:16 PM Revision 2649: dicts.py: Added is_dict()
Aaron Marcuse-Kubitza
05:06 PM Revision 2648: sql.py: DbConn.DbCursor.execute(): When setting self.query, provide default values for query, params because some debug printing statements use self.query directly instead of _add_cursor_info()
Aaron Marcuse-Kubitza
05:01 PM Revision 2647: sql.py: insert(): Fixed bug where column remaing needed to be removed and sql_gen.Literal value unwrapped
Aaron Marcuse-Kubitza
03:40 PM Revision 2646: sql.py: mk_insert_select(): cols: Fixed bug where table name needed to be removed from columns with a table
Aaron Marcuse-Kubitza
03:40 PM Revision 2645: sql_gen.py: ColDict: Only allow dict inputs to constructor so update() can later be used. Ensure keys_table is a Table object.
Aaron Marcuse-Kubitza
02:55 PM Revision 2644: sql_gen.py: ColDict: Translate NULL values to the key column's actual default value. This avoids incorrectly comparing against NULL in join/filter conditions when the column's actual default value must be used.
Aaron Marcuse-Kubitza
02:52 PM Revision 2643: sql.py: DbConn: Added col_default()
Aaron Marcuse-Kubitza
02:52 PM Revision 2642: sql_gen.py: ColDict: Take a db param for later use in getting default column values
Aaron Marcuse-Kubitza
02:16 PM Revision 2641: sql_gen.py: ColDict: Take a keys_table param for operations that require the output table. Use this to convert all string keys to sql_gen.Col objects.
Aaron Marcuse-Kubitza
01:55 PM Revision 2640: sql.py: put(): Use a sql_gen.ColDict for row, just like in put_table(), so that put() will benefit from planned enhancements to sql_gen.ColDict, such as translating NULL to the default value of a NOT NULL column
Aaron Marcuse-Kubitza
01:38 PM Revision 2639: schemas/functions.sql: _nullIf: Fixed bug where NOT NULL parameters were not supported, because an input NULL value would not match an existing DEFAULT value in a select query, by temporarily disabling _nullIf until this can be supported. Removed previous workarounds.
Aaron Marcuse-Kubitza

06/05/2012

03:21 PM Revision 2638: bin/map: out_is_db, row-based mode: Disabled using DB relational functions instead of XML functions because they were causing problems
Aaron Marcuse-Kubitza
03:18 PM Revision 2637: sql.py: put(): DuplicateKeyException: Fixed bug where select() call needs to be surrounded by value_or_none(), not value(), because sometimes there is no entry
Aaron Marcuse-Kubitza
03:17 PM Revision 2636: schemas/functions.sql: Added indexes on all relational function parameters since the unique index will not be used for lookups
Aaron Marcuse-Kubitza
02:29 PM Revision 2635: schemas/py_functions.sql: Added _namePart relational function
Aaron Marcuse-Kubitza
01:06 PM Revision 2634: schemas/py_functions.sql: Added _dateRangeEnd relational function
Aaron Marcuse-Kubitza
12:59 PM Revision 2633: main Makefile: schemas/%/uninstall: Removed delete confirmation message because it's repetitive to keep being asked to confirm deletion when running schemas/reinstall. schemas/%/uninstall is not intended to be run by itself, so the public schema's delete confirmation message will protect the entire schemas/uninstall sequence.
Aaron Marcuse-Kubitza
12:55 PM Revision 2632: schemas/py_functions.sql: _dateRangeStart(): Fixed bug where needed to get the first element of the array returned by parse_date_range()
Aaron Marcuse-Kubitza
12:32 PM Revision 2631: main Makefile: VegBIEN DB: Schemas: Changed to only allow reinstalling all schemas at once (using the usual `make schemas/reinstall` command), because reinstalling just one schema would silently remove anything in other schemas that depends on that schema
Aaron Marcuse-Kubitza
11:52 AM Revision 2630: schemas/py_functions.sql: Added _dateRangeStart relational function
Aaron Marcuse-Kubitza
10:53 AM Revision 2629: vegbien_dest: $schemas: Added py_functions
Aaron Marcuse-Kubitza
10:49 AM Revision 2628: pg_dump_vegbien: Fixed bug where needed space before $noOwners options
Aaron Marcuse-Kubitza
10:37 AM Revision 2627: main Makefile: VegBIEN DB: DB and bien user: mk_db: Also `createlang plpythonu`
Aaron Marcuse-Kubitza
10:26 AM Revision 2626: pg_dump_vegbien: Log the pg_dump command being run
Aaron Marcuse-Kubitza
10:23 AM Revision 2625: main Makefile: VegBIEN DB: DB and bien user: Added schemas/py_functions/reset. db: Create py_functions schema.
Aaron Marcuse-Kubitza
10:22 AM Revision 2624: main Makefile: VegBIEN DB: DB and bien user: Added schemas/py_functions/reset. db: Create py_functions schema.
Aaron Marcuse-Kubitza
10:16 AM Revision 2623: schemas/py_functions.sql.make: Fixed bug where owners needed to be included because schema is imported as superuser so that untrusted PL/Python functions can be created
Aaron Marcuse-Kubitza
10:15 AM Revision 2622: pg_dump_vegbien: Support optionally including owners
Aaron Marcuse-Kubitza
09:59 AM Revision 2621: main Makefile: VegBIEN DB: DB and bien user: Factored $(confirmRm<schema>) functions message text out into $(confirmRmSchema) function
Aaron Marcuse-Kubitza
09:52 AM Revision 2620: schemas/Makefile, py_functions.sql.make: Generate py_functions.sql from vegbien's py_functions schema
Aaron Marcuse-Kubitza
09:32 AM Revision 2619: main Makefile: postgres-Linux: Install postgresql-plpython
Aaron Marcuse-Kubitza
09:27 AM Revision 2618: main Makefile: python-Linux, postgres-Linux: Fixed bug where apt-get installs needed to each be run in a separate command, so that if any package was not found, the other packages would still install. (apt-get aborts on the first invalid package name.)
Aaron Marcuse-Kubitza

Aaron Marcuse-Kubitza
08:01 AM Revision 2613: sql_gen.py: add_suffix(): Fixed bug where only strings already at the max length had the version preserved, even though appending the suffix could bring it past the max length and still cause the version to be overwritten. Fixed bug where last # in str, not first, should be considered to precede the version.
