07/20/2012
- 07:10 AM Revision 3541: schemas/py_functions.sql: _date(): Re-enabled now that exceptions thrown are properly handled. FormatException: Support raising parsable data_exceptions when provided with the value that was invalid. Date parsing mode: Return date as the value in FormatException so it can be filtered out automatically by column-based import.
- 07:06 AM Revision 3540: sql_io.py: put_table(): is_function: Creating error handling wrapper function: Fixed bug where needed to cast NULL returned in error handler to appropriate type, because it's contained within a SELECT query which does not do implicit casts from type unknown
- 07:03 AM Revision 3539: sql_gen.py: Cast: Support types which are Code objects
- 06:32 AM Task #424: Finish translating XML functions to SQL functions for column-based import
- Core XML functions have been translated.
Sandboxing has been added to allow SQL functions to throw exceptions. - 06:31 AM Task #378: create automated feedback mechanism
- SQL function errors are now also saved using this mechanism.
- 06:05 AM Revision 3538: sql_io.py: func_wrapper_exception_handler(): Use new sql_gen.merge_not_null() to try to ensure that NULL values are not folded (which would cause the concatenated values not to match up with the concatenated column names). Note that this adds a dependency on the db object, which callers must now provide.
- 06:03 AM Revision 3537: sql_gen.py: Added merge_not_null()
- 06:03 AM Revision 3536: sql_gen.py: Added try_mk_not_null()
- 05:54 AM Revision 3535: sql_gen.py: Renamed ArrayJoin to ArrayMerge to avoid confusion with Join (a SQL construct)
- 05:46 AM Revision 3534: sql_io.py: put_table(): is_function: Creating error handling wrapper function: Set srcs on row_var so that the column type and nullability info of row_var's columns can be retrieved for use with sql_gen.ensure_not_null()
- 05:38 AM Revision 3533: sql_gen.py: RowExcIgnore.to_str(): Compare self.row_var to global const row_var using == to allow caller to provide a copy of row_var with the underlying table set appropriately
- 05:35 AM Revision 3532: sql_gen.py: underlying_table(): Support derived tables and row vars by obtaining the underlying table from the srcs
- 05:25 AM Revision 3531: sql_io.py: put_table(): Setting pkeys of missing rows: Fixed bug where also needed to do this when is_function if an empty pkeys table was created (due to an error that could not be localized to a row)
- 05:16 AM Revision 3530: sql_io.py: put_table(): After main loop: If is_literals, return immediately to avoid needing to test for is_literals in all the code that follows (which only applies to the normal case)
- 04:43 AM Revision 3529: sql_gen.py: RowExcIgnore: If a custom row_var is used, require it to already be defined. This also allows sql_io.ExcToErrorsTable to place the column var definition in the outer DECLARE, eliminating the extra DECLARE block.
- 04:30 AM Revision 3528: sql_io.py: put_table(): is_function: Creating error handling wrapper function: Use new sql_gen.row_var
- 04:28 AM Revision 3527: sql_gen.py: RowExcIgnore: Created global constant for default row_var for callers to use
- 04:24 AM Revision 3526: sql_gen.py: RowExcIgnore.to_str(): Moved SQL comment explaining the use of an EXCEPTION block for each individual row to Python code to avoid cluttering the logged SQL code
- 04:19 AM Revision 3525: sql_io.py: put_table(): is_function: Creating error handling wrapper function: Handle errors using new func_wrapper_exception_handler(), which saves any data_exceptions in the errors table in addition to handling PL/Python errors
- 04:13 AM Revision 3524: sql_io.py: Added func_wrapper_exception_handler()
- 04:10 AM Revision 3523: sql_gen.py: Added ArrayJoin
- 04:10 AM Revision 3522: sql_gen.py: Added Array and to_Array()
- 02:47 AM Revision 3521: sql_gen.py: Added List and inherit from it in Tuple
- 02:45 AM Revision 3520: sql_gen.py: Renamed Tuple to Row and List to Tuple to more accurately reflect the datatype generated by each class (a Tuple being merely a grouping of values)
- 02:43 AM Revision 3519: sql_gen.py: Moved Composite types to Literal values section as a subsection, since Composite types was really about just the input syntaxes for these types
- 02:32 AM Revision 3518: sql_gen.py: Replaced srcs_str() with cross_join_srcs() which more correctly combines the srcs of each column using a Cartesian product. Eventually, the entire tree of srcs will need to be preserved instead of flattened in order to properly attribute errors to a specific column or set of columns.
- 02:03 AM Revision 3517: sql_gen.py: srcs_str(): Fixed bug where needed to filter out columns with no srcs so that there aren't empty elements in the ","-separated list
- 02:00 AM Revision 3516: sql_gen.py: Added has_srcs()
- 01:44 AM Revision 3515: sql_gen.py: Added NestedExcHandler
- 01:44 AM Revision 3514: sql_gen.py: Added srcs_str()
- 01:43 AM Revision 3513: sql_gen.py: as_Col(): Support non-Code, non-string inputs by making them Literals
- 01:42 AM Revision 3512: sql_gen.py: Added is_col() and use it in is_table_col()
07/19/2012
- 11:54 PM Revision 3511: sql_io.py: ExcToErrorsTable: Require users to explicitly specify an expression for the value that caused the error, instead of assuming that a variable named "value" already exists. This allows a value expression to be computed only if needed for error handling.
- 11:22 PM Revision 3510: sql_gen.py: Moved __repr__() from ExcHandler to BaseExcHandler
- 11:21 PM Revision 3509: sql_gen.py: Added BaseExcHandler and inherit from it in ExcHandlers
- 10:58 PM Revision 3508: sql_io.py: cast(): Determining if will be saving errors: Don't add extra check if isinstance(col, sql_gen.Col) because the special case for sql_gen.Literal handles supported non-columns
- 10:56 PM Revision 3507: sql_io.py: data_exception_handler(): Removed no longer needed db param
- 10:47 PM Revision 3506: sql_io.py: Added ExcToErrorsTable, which separates out the errors table inserting code from the exception handling code. data_exception_handler(): Refactored to use new sql_gen.data_exception_handler() and ExcToErrorsTable.
- 10:43 PM Revision 3505: sql_gen.py: Added data_exception_handler
- 10:08 PM Revision 3504: sql_io.py: data_exception_handler(): Refactored to use new sql_gen.ExcToWarning when not using an errors table
- 10:03 PM Revision 3503: sql_gen.py: Added ExcToWarning
- 10:02 PM Revision 3502: schemas/vegbien.sql: taxondetermination: taxondetermination_taxonoccurrence_id_fkey(): Fixed bug where string containing a \-escape needed an "E" prefix
- 09:42 PM Revision 3501: sql_io.py: data_exception_handler(): Require the caller to provide a statement to return a default value in case of error, rather than assuming the caller can accept a return value of NULL
- 09:27 PM Revision 3500: sql_io.py: data_exception_handler(): Refactored to use new sql.define_func()
- 09:20 PM Revision 3499: sql_io.py: put_table(): is_function: Calling function on input rows: Convert PL/Python exceptions (internal_errors) to data_exceptions using sql_gen.plpythonu_error_handler and an error handling wrapper function
- 09:10 PM Revision 3498: debug2redmine.csv: EXPLAIN comments: Fixed bug where needed to also match whitespace at beginning of line (indent)
- 09:07 PM Revision 3497: Use sql_gen.ReturnQuery where RETURN QUERY was previously manually prepended
- 09:05 PM Revision 3496: sql_gen.py: Added ReturnQuery
- 08:48 PM Revision 3495: sql.py: define_func(): Fixed bug where next_version() needed to have module name removed since it's in the same module
- 08:47 PM Revision 3494: sql.py: mk_select(): Added explain param to turn off automatically running EXPLAIN on the created query. This is useful for SELECT statements which use local variables in PL/pgSQL functions.
- 08:44 PM Revision 3493: sql_gen.py: with_table(): Only set the table if the passed-in value is a Col or FunctionCall
- 08:41 PM Revision 3492: sql_gen.py: Added Tuple
- 08:41 PM Revision 3491: sql_gen.py: Added List and use it in Values.to_str()
- 08:14 PM Revision 3490: sql.py: Added define_func()
- 07:07 PM Revision 3489: Use sql_gen.SetOf where SETOF was previously manually prepended
- 07:06 PM Revision 3488: sql_gen.py: Added SetOf
- 07:06 PM Revision 3487: sql_gen.py: FunctionDef: Support return_types which are Code objects
- 06:55 PM Revision 3486: Use sql_gen.ColType where %TYPE was previously manually appended
- 06:54 PM Revision 3485: sql_gen.py: Added ColType
- 06:47 PM Revision 3484: Use sql_gen.RowType where %ROWTYPE was previously manually appended
- 06:45 PM Revision 3483: sql_gen.py: Added RowType
- 06:45 PM Revision 3482: sql_gen.py: RowExcIgnore: Accept row types which are Code objects
- 06:42 PM Revision 3481: sql_gen.py: TypedCol: Accept types which are Code objects
- 06:34 PM Revision 3480: sql_io.py: data_exception_handler(): Documented that the invalid value must be in a local variable of type text
- 06:33 PM Revision 3479: sql_io.py: data_exception_handler(): Documented that the invalid value must be in a local variable of type text
- 06:32 PM Revision 3478: sql_io.py: put_table(): is_function: Creating empty pkeys table so its row type can be used: Don't do this if is_literals because special error handling does not apply to that
- 06:13 PM Revision 3477: sql_io.py: put_table(): is_function: Create empty pkeys table before calling function on all rows so its row type can later be used in an error handling wrapper function
- 05:56 PM Task #446 (New): fix deadlock in INSERT IGNORE replacement
- h3. Possible solutions
# -retry query on TransactionRollbackError-: _done, but doesn't fix the underlying problem ... - 05:33 PM Revision 3476: input.Makefile: Staging tables: import/install-%: Run csv2db with a nice increment of +5 to avoid interfering with the user's other processes
- 05:28 PM Revision 3475: root map: Run bin/map with a nice increment of +5 to avoid interfering with the user's other processes
- 05:24 PM Revision 3474: sql_io.py: put_table(): Handle psycopg2.extensions.TransactionRollbackError by retrying the last query
- 05:00 PM Revision 3473: sql_io.py: Creating an empty output pkeys table: Assert that there are no join columns, so that the input pkeys table will be created correctly for the empty output pkeys table
- 04:53 PM Revision 3472: sql_io.py: put_table(): Creating an empty output pkeys table: Added "output" to clarify that the created table contains just the output pkeys, and must be joined with the input pkeys table
- 04:39 PM Revision 3471: sql_gen.py: FunctionDef: Renamed args to params
- 04:35 PM Revision 3470: sql_gen.py: FunctionDef: Accept parameters as FunctionParam objects instead of strings
- 04:32 PM Revision 3469: sql_gen.py: Added FunctionParam
- 04:04 PM Revision 3468: sql_gen.py: Added plpythonu_error_handler
07/18/2012
- 11:06 PM Revision 3467: Autogenerated SQL code: Use new strings.indent() where needed
- 11:05 PM Revision 3466: strings.py: Added indent()
- 10:50 PM Revision 3465: sql_io.py: data_exception_handler(): Refactored to use sql_gen.RowExcIgnore
- 10:31 PM Revision 3464: sql_io.py: cast(): Refactored to use sql_gen.FunctionDef
- 10:28 PM Revision 3463: sql_gen.py: ExcHandler: Removed extra newline after handler
- 10:27 PM Revision 3462: sql.py: mk_insert_select(): ignore: RETURN QUERY statement: Added back missing newline after ';'
- 10:23 PM Revision 3461: sql_gen.py: FunctionDef: Added support for parameters
- 10:03 PM Revision 3460: sql_io.py: cast(): Just use the first word of the type in the function name to help avoid name collisions. Note that type name collisions that may be introduced by this change are not a problem because the function name is versioned. (The caching mechanism prevents versioning when the function has the same name and definition as an already-defined function.)
- 09:59 PM Revision 3459: sql_io.py: Added data_exception_handler() and use it in cast()
- 09:58 PM Revision 3458: sql_gen.py: ExcHandler.to_str(): Removed extra newline after body
- 08:41 PM Revision 3457: sql_gen.py: ExcHandler: Added __repr__() since it's not a Code object
- 08:17 PM Revision 3456: sql_gen.py: FunctionDef: Support custom function modifiers
- 08:04 PM Revision 3455: sql_gen.py: RowExcIgnore: Changed exc param to exc_handler to allow user to specify handler code for the exception
- 08:01 PM Revision 3454: sql_gen.py: Added ExcHandler, unique_violation_handler
- 07:53 PM Revision 3453: sql_gen.py: RowExcIgnore: Don't automatically add 'RETURN QUERY' before the with_row code or ';' after it
- 07:02 PM Revision 3452: sql_gen.py: RowExcIgnore: Allow user to specify a custom row var name
- 06:55 PM Revision 3451: sql_gen.py: FunctionDef: Don't automatically add 'SETOF ' before the return type
- 06:44 PM Revision 3450: sql.py: mk_insert_select(): embeddable: Use new sql_gen.RowExcIgnore
- 06:44 PM Revision 3449: sql_gen.py: Added RowExcIgnore
- 06:12 PM Revision 3448: sql_gen.py: FunctionDef: Determine the lang from the body's Code object instead of receiving it as a parameter
- 06:10 PM Revision 3447: sql_gen.py: as_Code(): Fixed bug where needed to handle inputs that are already Code objects
- 05:52 PM Revision 3446: sql_gen.py: Code: Added lang instance var
- 05:49 PM Revision 3445: sql_gen.py: Fixed bug where Code subclasses needed to call Code.__init__() in their __init__() function. BasicObject: Fixed bug where __init__() expected a value param, when in fact the value param is something added by certain subclasses.
- 05:31 PM Revision 3444: sql_gen.py: FunctionDef: body param: Support Code inputs in addition to strings
- 05:14 PM Revision 3443: sql.py: mk_insert_select(): embeddable: Use new sql_gen.FunctionDef
- 05:13 PM Revision 3442: sql_gen.py: Added FunctionDef
- 03:49 PM Revision 3441: README.TXT: Schema changes: Documented how to reinstall errors tables
- 03:46 PM Revision 3440: csv2db: Creating errors table: Only drop existing errors table in errors_table_only mode, so that errors tables are not unintentionally deleted when `make inputs/install` is run. This helps to make `make install` idempotent.
- 03:40 PM Revision 3439: README.TXT: Maintenance: Full DB: Changed commands to autorotate the created backup and then test and restore a rotated backup
- 03:31 PM Revision 3438: backups/Makefile: Added %.backup/rotate
- 02:58 PM Revision 3437: backups/Makefile: Rearranged sections so that backup targets, which apply to both Archived imports and Full DB, are at the top of a common Backups section
- 02:54 PM Revision 3436: inputs/import.stats.xls: Updated with stats from latest import
07/17/2012
- 11:09 PM Revision 3435: schemas/py_functions.sql: Disabled _date() because it does not yet output errors in a format parsable by the import process, and the import process does not yet trap errors produced by SQL functions
- 11:00 PM Revision 3434: sql_io.py: put_table(): Determining if can use optimization for only literal values: Fixed bug where needed initial value for reduce()
- 10:52 PM Revision 3433: sql_io.py: put_table(): Needing >= one column for INSERT SELECT: Fixed bug where can't add pkey column if calling a function instead of outputting to a table
- 10:36 PM Revision 3432: sql_io.py: put_table(): Optimization for only literal values: Also support an empty in_tables list, for use by put()
- 10:20 PM Revision 3431: sql_io.py: put_table(): Added optimization for only literal values, which does the same operations as put() but with the additional error handling of put_table()
- 10:17 PM Revision 3430: pg_dump_vegbien: Don't use SET SESSION AUTHORIZATION because it doesn't work with the py_functions schema (it requires PL/Python functions to be created as user postgres and then the owner changed to bien, which SET SESSION AUTHORIZATION won't do)
- 08:53 PM Revision 3429: sql_gen.py: Added is_literal() and use it where isinstance(..., Literal) is used
- 08:44 PM Revision 3428: db_xml.py: put_table(): Divide fields into input columns and literal values: Translate values: Allow literal values other than strings or None (from the XML parsing), because sql_io.put_table() is getting an optimization for iterations containing only literal values, which just returns the pkey of the single row for these values (which is usually an integer) instead of a temp table with the same value in each row
- 08:28 PM Revision 3427: bin/map: by_col: Stripping XML functions not in the DB: Remove DB functions based on whether a plain SQL function of that name exists, rather than whether a relational function (i.e. a table) of that name exists. This will allow column-based import to use plain SQL functions that don't have a corresponding relational function.
- 08:23 PM Revision 3426: db_xml.py: Don't remove any explicit pkey because the output table may be a SQL function, which does not have a pkey. This feature only existed to support importing VegBank XML exports, which we don't use (and which would be incompatible with the schema anyway).
- 08:19 PM Revision 3425: sql.py: function_exists(): Fixed bug where select() needed to be run with auto-rollback in case it raised an exception
- 08:08 PM Revision 3424: xml_func.py: process(): Changed rel_funcs param to a callback is_rel_func, so that caller can specify any dynamic function to determine if a name is a relational function rather than having to list out all known relational functions
- 07:54 PM Revision 3423: sql.py: function_exists(): Use simpler cast to regproc instead of query of information_schema.routines to determine if function exists. When the schema is not specified, this also limits the schemas checked to the search_path instead of the whole DB.
- 07:51 PM Revision 3422: schemas/functions.sql, py_functions.sql: Renamed trigger functions to avoid collisions with plain SQL functions of the same name but different signatures, so that the plain SQL functions can be uniquely identified by their name without also requiring their signature
- 07:39 PM Revision 3421: sql.py: mk_select(): In queries without a FROM clause, don't order by pkey
- 07:15 PM Revision 3420: sql.py: mk_select(): Support queries without a FROM clause
- 07:03 PM Revision 3419: sql.py: Added DoesNotExistException and parse it in run_query()
- 06:46 PM Revision 3418: sql_io.py: put_table(): Removed no longer used conds var (invalid rows are removed from the in_table using sql.delete() instead of being filtered out in the main select)
- 06:43 PM Revision 3417: sql_io.py: put_table(): Removed no longer used distinct_on var (sql.distinct_table() handles filtering the join_cols)
- 06:24 PM Revision 3416: schemas/py_functions.sql: _date(): Just run str() on the returned datetime because it will usually be converted to a PostgreSQL timestamp anyway, so excluding the time from the string isn't necessary
- 06:15 PM Revision 3415: schemas/py_functions.sql: Added _date()
- 06:14 PM Revision 3414: sql.py: run_query(): Exception parsing: Remove PL/Python prefix from exception message so that the regexps can match at the beginning of the message
- 05:50 PM Revision 3413: sql_io.py: put_table(): Handle sql.InvalidValueExceptions by filtering the value out of all input columns. This will be useful for SQL functions that raise exceptions.
- 04:49 PM Revision 3412: schemas/vegbien.sql: namedplace, plantname: *_unique UNIQUE INDEX: Reordered columns to put rank after parent_id and plantname so that these columns, which are usually input table columns, can be used in a merge join index scan, while rank, which is usually a literal value, can applied as an index filter condition after the merge join
- 04:42 PM Revision 3411: sql.py: distinct_table(): Removed literal values from UNIQUE INDEXes because the query planner did not seem to use them to do a merge join
- 04:01 PM Revision 3410: README.TXT: Maintenance: Full DB: Documented how to test full DB backup
- 03:58 PM Task #443 (Resolved): back up staging tables
- They have now been backed up as part of the full DB backup[1].
fn1. @make backups/vegbien.backup &@ - 03:51 PM Task #442 (Resolved): test restoring of import backups
- I tested restoring by extracting the compressed, custom-format backup to a plain text SQL script[1]. This is much fas...
- 03:47 PM Revision 3409: backups/Makefile: Added %.backup/test
- 03:39 PM Task #444 (Resolved): test backing up entire DB
- 03:35 PM Task #444: test backing up entire DB
- Full DB backup is 2.5 GB (compressed) and takes ~45 min[1]. Testing takes 3.5 min[2].
fn1. @make backups/vegbien.bac...
07/16/2012
- 08:32 PM Revision 3408: README.TXT: Documented maintenance of full DB (back up/restore)
- 08:23 PM Revision 3407: backups/Makefile: Full DB backups: Added vegbien.backup
- 08:22 PM Revision 3406: pg_dump_vegbien: If first arg is "all", dump entire DB. Require a first arg so that Usage message will be displayed if run with no args.
- 08:03 PM Revision 3405: Always output Usage messages to stderr and word-wrap them using `fold -s`
- 07:37 PM Revision 3404: backups/Makefile: Factored backup command into $(backup) for later use by full DB backups. Made Backups, Archived imports sections subsections of Archived imports so Full DB backups can have its own section.
- 07:16 PM Revision 3403: backups/Makefile: Fixed bug where $(SHELL) needed to be set to bash so that $'\n' would be interpreted correctly
- 07:06 PM Revision 3402: backups/Makefile: Fixed bug where *.sql files needed to be restored using psql because pg_restore only supports "non-plain-text formats"
- 06:35 PM Revision 3401: pg_dump_vegbien: For consistency with setting the --schema option, use `set -- "$@" args...` to append options to $@ which are then passed to pg_dump, instead of specifying several variables which are then included in the pg_dump command
- 06:26 PM Revision 3400: pg_dump_vegbien: Pass command line options directly to pg_dump after parsing out any schema name
- 06:19 PM Revision 3399: backups/Makefile: Don't log stderr or run the command verbosely and instead just output the command and run time to the terminal. This matches what we do for pg_dump, which works better because it just prints the useful information when it's done running.
- 05:28 PM Revision 3398: backups/Makefile: Remove log files after successful restore/extraction because they are only useful for tail -f when the restore operation is running in the background
- 05:14 PM Revision 3397: pg_dump_vegbien: Save owners when saving data (for full export)
- 05:03 PM Revision 3396: pg_dump_vegbien: Use SET SESSION AUTHORIZATION to ensure that owners are always recorded in the same format. This will help make plain text backups comparable using diff.
- 04:39 PM Revision 3395: backups/Makefile: Backups: Fixed bug where `%.sql: %` needed to come before %.sql with no prerequisites to be matched first
- 04:20 PM Task #442: test restoring of import backups
- Options:
* "testing if the export can be restored":http://www.linuxquestions.org/questions/linux-software-2/testing-... - 02:53 PM Task #442: test restoring of import backups
- Google techniques for this
- 02:52 PM Task #442 (Resolved): test restoring of import backups
- 04:14 PM Revision 3394: Moved archived imports and make targets to maintain them to new backups dir
- 04:08 PM Revision 3393: Moved archived imports and make targets to maintain them to new backups dir
- 03:29 PM Revision 3392: Added psql_script_vegbien
- 02:52 PM Task #444 (Resolved): test backing up entire DB
- * run time
* storage space - 02:52 PM Task #443 (Resolved): back up staging tables
- 02:51 PM Task #441 (Resolved): import CTFS data using JOINs from DB export, not VegX
- 02:50 PM Task #440: aggregating validations of imports
- Have the # of:
* records
* plots
* specimens
* taxonomic categories
* species
* locations - 02:49 PM Task #440: aggregating validations of imports
- update for current schema
- 02:48 PM Task #440 (New): aggregating validations of imports
- 12:54 PM Revision 3391: root Makefile: VegBIEN DB: Schemas: Added schemas/%.sql to extract a compressed custom-format backup to plain SQL
- 12:33 PM Revision 3390: root Makefile: VegBIEN DB: Schemas: Added schemas/%.backup/uninstall so that a schema can be removed by its backup file name (with extension) as well as its name
07/13/2012
- 04:43 PM Revision 3389: README.TXT: Documented that files and directories can easily be remade with `make <file>-remake` and `make <dir>/remake`, which do the make clean or rm automatically
- 04:37 PM Revision 3388: pg_dump_vegbien: Added plain env var which creates plain text output instead, for use in debugging and validation
- 04:14 PM Revision 3387: input.Makefile: Mapping: $(map): Fixed bug where use_staged was causing in_schema, in_database, etc. to be set even when not outputting to vegbien, causing bin/map to try to output to a DB when it should output to stdout, by moving the use_staged test to $(map2db)
- 03:07 PM Revision 3386: sql_io.py: put_table(): Creating full_in_table: If out_table is a SQL function, just use in_table because in_table is not modified
- 02:47 PM Revision 3385: input.Makefile: Documentation: import/steps.by_col.sql: $(steps): Fixed bug where stderr needed to be redirected to stdout so that it would be passed to debug2redmine and included in the file
- 02:26 PM Revision 3384: root Makefile: Datasources: import: Don't pause after "To import all inputs at once" message because this prevents running sequential import with & (as `make import &`)
- 02:09 PM Revision 3383: sql.py: create_table(): Only version temp tables, so that e.g. staging tables are not created with a version # if they already exist. This will help make `make install` idempotent.
- 02:00 PM Revision 3382: input.Makefile: Import to VegBIEN: $(import): Only redirect stderr to stdout if outputting to a log file. This allows unlogged imports to redirect the "Inserted # new rows into database" message, which is output to stdout rather than stderr for use by validation and automated testing, to a separate location.
- 01:54 PM Revision 3381: README.TXT: Documented how to remove an archived import. Moved archived imports commands from Data import to new section Maintenance of archived imports. Changed "Empty the DB" to "Remove the last import" for clarity, and made the command apply just to the public schema and not also to the functions schemas (reinstalling those is documented under Schema changes).
- 01:44 PM Revision 3380: root Makefile: $(rmSchemaCmd) for uninstalling schemas: Escape schema name with "" so that schemas/%/uninstall can be used to remove archived imports (as well as aborted restores of them)
- 01:14 PM Revision 3379: root Makefile: schemas/%.backup: Removed explicit check if file exists because now that the target name matches the name of the file created, the file will be rebuilt only if it doesn't exist
- 01:13 PM Revision 3378: schemas: Ignore log files (from restore operations) for svn
- 12:49 PM Revision 3377: main Makefile: Installation: install: Download input data using new inputs/download target
- 12:48 PM Revision 3376: main Makefile: VegBIEN DB: Schemas: schemas/%/install, schemas/py_functions/install: Ignore errors if schema exists, so that install can be idempotent
- 12:38 PM Revision 3375: inputs/Makefile: Added download to download input data from vegbiendev
- 10:05 AM Revision 3374: main Makefile: VegBIEN DB: Removing database warning message: Changed "public schema versions" to "archived imports" for clarity
- 10:01 AM Revision 3373: main Makefile: VegBIEN DB: Schemas: Added schemas/%.backup/restore and documented it in README.TXT
- 09:42 AM Revision 3372: inputs/import.stats.xls: Updated with stats from latest import. Marked partial imports affecting the slowest datasource with a comment when they might otherwise appear to be comparable with full imports due to having a similar # of rows.
- 08:58 AM Revision 3371: root Makefile: schemas/%.backup: Removed _always prerequisite because an existing backup should not be overwritten by running `make schemas/%.backup`
- 08:53 AM Revision 3370: README.TXT: Updated warning messages to match what's actually output by the commands in question
- 08:47 AM Revision 3369: README.TXT: Documented how to back up an archived import
07/12/2012
- 03:26 PM Revision 3368: root Makefile: VegBIEN DB: Schemas: schemas/%/backup: Time the backup
- 03:25 PM Revision 3367: root Makefile: VegBIEN DB: Schemas: schemas/%/backup: Renamed to the name of the file created (schemas/%.backup) so that the file will automatically be removed by make if you cancel the backup. If this didn't happen, the existing partial file would prevent make from backing it up again.
- 03:19 PM Revision 3366: schemas: Ignore *.backup files for svn
- 03:00 PM Revision 3365: root Makefile: VegBIEN DB: Schemas: schemas/%/backup: Documented that it can't be used for the current (unrotated) public schema because pg_dump doesn't back up the CREATE SCHEMA statement for it
- 02:45 PM Revision 3364: root Makefile: VegBIEN DB: Schemas: schemas/%/backup: Changed file extension to .backup to match what pgAdmin3 expects
- 02:40 PM Revision 3363: inputs/SALVIAS/maps/VegX.stems.csv: Fixed PlotObsID mapping to point to sourceAccessionCode so that it would map to the same place as organisms' PlotObsID and the entries would be merged. This will hopefully also fix a SALVIAS stems import bug where the specimenreplicate join on existing/inserted rows matched multiple rows, in spite of using the specimenreplicate_unique_catalognumber UNIQUE INDEX.
- 02:35 PM Revision 3362: root Makefile: VegBIEN DB: Schemas: Added schemas/%/backup for backing up an import's schema
- 02:34 PM Revision 3361: pg_dump_vegbien: Added data option for backing up an import's schema
- 01:32 PM Revision 3360: sql_io.py: cast(): Don't output warnings for errors that are stored in the errors table, because this clutters the log output unnecessarily. Warnings are still output when there is no errors table.
- 01:20 PM Revision 3359: schemas/vegbien.sql: party: party_unique UNIQUE INDEX: Moved surname before givenname, middlename to enable the index to be used when just the person's last name is known. (Note that if the organization is not known, and explicit NULL would need to be put in for that field to use the index.)
- 01:14 PM Revision 3358: sql_io.py: put_table(): DuplicateKeyException: Uniquifying input table to avoid internal duplicate keys: Include all join columns (including literal values) in the unique index, not just table columns, to encourage PostgreSQL to use the index in a merge join.
- 01:11 PM Revision 3357: sql.py: distinct_table(): Support literal values as column expressions. Filter out untyped NULLs because the type unknown can't be indexed.
- 01:09 PM Revision 3356: sql.py: add_index(): Support literal values as expressions
- 01:06 PM Revision 3355: sql_gen.py: ensure_not_null(): Support Literal value inputs, which are passed through if not nullable
- 01:05 PM Revision 3354: sql_gen.py: Added cast_literal()
- 11:52 AM Revision 3353: sql.py: Added simplify_expr() and use it in parse_expr_col(). This will remove extraneous information from the condition that gets included in the errors table, so it's easy for the data provider to see what constraint is being violated as it applies to their data.
- 11:40 AM Revision 3352: sql_io.py: put_table(): Handle CheckExceptions. This fixes a REMIB bug where some rows violated the specimenreplicate.specimenreplicate_required_key CHECK constraint, but there was previously no way to filter out just these rows so all rows were removed instead.
- 11:33 AM Revision 3351: sql.py: Added map_expr()
- 11:33 AM Revision 3350: sql_gen.py: Added NotCond
- 10:06 AM Revision 3349: sql.py: run_query(): ConstraintException: Get and include the constraint condition in the exception
- 10:05 AM Revision 3348: sql.py: Added constraint_cond()
- 09:26 AM Revision 3347: sql.py: run_query(): ConstraintException: Include table in the constraint name because constraints are scoped by table
- 09:18 AM Revision 3346: sql.py: Added ConstraintException and parse it in run_query()
- 09:12 AM Revision 3345: sql.py: ConstraintException: Also store the constraint's condition, if any
- 08:24 AM Revision 3344: schemas/vegbien.sql: specimenreplicate: specimenreplicate_unique_catalognumber UNIQUE INDEX: Limited to rows where sourceaccessioncode IS NULL, so that it will only be used as an alternate if the datasource does not specify a sourceaccessioncode. This should fix the SpeciesLink bug where input rows with catalognumber_dwc IS NULL match multiple output rows when compared on the specimenreplicate_unique_catalognumber UNIQUE INDEX because they were excluded from the uniquifying by the index filter.
- 08:10 AM Revision 3343: schemas/vegbien.ERD.mwb: Synced with schema
- 08:06 AM Revision 3342: schemas/vegbien.sql: specimenreplicate: Added UNIQUE INDEX on plantobservation_id for direct vouchers in plots data
- 07:16 AM Revision 3341: inputs/import.stats.xls: Updated with stats from latest import
07/11/2012
- 10:36 PM Revision 3340: sql.py: Removed no longer used constraint_cols(). index_cols() can always be used for a UNIQUE constraint because a UNIQUE index is automatically created for it.
- 10:34 PM Revision 3339: bin/map: Fixed bug where errors table indexes could not be looked up using index_cols() because their schema was not in the search_path, by explicitly adding the in_schema at the end of the search_path. This is the only reason the in_schema needs to be in the search_path, but it's unavoidable because the "duplicate key value violates unique constraint" error does not included the constraint's schema.
- 10:24 PM Revision 3338: sql.py: run_query(): DuplicateKeyException: Don't parse table name out of constraint name because it isn't used and can't reliably be determined for table names containing "_"
- 09:10 PM Revision 3337: mappings/VegX-VegBIEN.stems.csv: Reattached location.datasource_id :[] mappings directly to the location itself, rather than to the location via the locationevent
- 08:37 PM Revision 3336: mappings/VegX-VegBIEN.stems.csv: Mapped to taxonoccurrence.sourceaccessioncode to avoid underconstraining taxonoccurrence
- 08:02 PM Revision 3335: xml_func.py: process(): Merge mergeable siblings recursively so that newly-mergeable children are also merged
- 07:44 PM Revision 3334: xml_dom.py: Removed no longer used merge_same_name()
- 07:43 PM Revision 3333: xml_func.py: process(): Recombining pieces of nodes that were split apart in the mappings: Only combine nodes that are explicitly marked as mergeable, to avoid unwanted merges. Refactored to use new xml_dom.merge_by_name().
- 07:39 PM Revision 3332: mappings/VegX-VegBIEN.stems.csv: Marked aggregateoccurrence as mergeable, in preparation for switching to explicit merging only to avoid unwanted merges
- 07:33 PM Revision 3331: xml_dom.py: Moved merge_adjacent() recursion and name checking into merge() so that other callers of merge() can take advantage of it, too. Added merge_by_name() and use it in merge_same_name(). Removed now-unused merge_adjacent().
- 07:30 PM Revision 3330: xpath.py: get(): Support checking all children when the elem name is '*'
- 07:01 PM Revision 3329: xml_dom.py: replace(): Assert that old node not removed from parent tree
- 06:44 PM Revision 3328: xpath.py: Added is_all()
- 06:17 PM Revision 3327: xml_func.py: process(): List out the xml_dom.NodeElemIter iterator so that it won't be affected by concurrent changes to the DOM tree
- 05:32 PM Revision 3326: xml_func.py: process(): Merging children: Support merging non-adjacent children by using new xml_dom.merge_same_name(). This should eliminate the need to sort children of the same name next to each other in the mappings so that they will be merged.
- 05:30 PM Revision 3325: xml_dom.py: Added merge_same_name()
- 05:15 PM Revision 3324: bin/map: ex_tracker: Don't add row_ct to iters count in column-based import (by_col) because errors are not done by row, so a % of rows affected is not meaningful
- 05:13 PM Revision 3323: sql_io.py: put_table(): NullValueException: Missing mapping for NOT NULL column: Raise error if there is no default input column to fill in the rows with. Missing mappings for required columns are a normal circumstance with path mappings (plantname, namedplace) because the mappings include intervening levels that may not be specified by the datasource. These mappings have default input columns for the intervening levels, so for them, this will continue to not be flagged as an error.
- 04:55 PM Revision 3322: sql.py: index_cols(): Fixed bug where index columns were sorted by their position in the table, not their position in the index. This was causing the order of columns in covering indexes not to match their order in the corresponding output table index, preventing merge joins and slowing down joins because of the need to do a seq scan. Refactored to use pg_get_indexdef() on each column position index and parsing the result with parse_expr_col(), which *greatly* simplifies the query and automatically provides the correct sort order.
- 04:50 PM Revision 3321: sql.py: Added parse_expr_col()
- 04:50 PM Revision 3320: sql_gen.py: Added unesc_name()
- 04:02 PM Revision 3319: sql.py: index_cols(): Removed unneeded table param, since the index name is unique within its schema. (The schema is looked up in the search_path if needed, by using ::regclass.)
- 03:59 PM Revision 3318: sql.py: index_cols(): Fixed bug where index was looked up only by name, not by schema-qualified name, causing columns from other schemas (such as previous versions of public) to be included in the index columns list. This problem is only noticeable when a column in an index is deleted, as locationevent.datasource_id in locationevent_unique_accessioncode was recently.
07/10/2012
- 09:53 PM Revision 3317: input.Makefile: Name logs with extension .log.sql so they are syntax-highlighted for the SQL statements they contain
- 09:24 PM Revision 3316: schemas/vegbien.sql: taxonoccurrence: Added sourceaccessioncode so that taxonoccurrences can be uniquely identified in plots data
- 09:12 PM Revision 3315: schemas/vegbien.sql: locationevent: Removed datasource_id because locationevents are now scoped by their required location, which itself is scoped by datasource
- 09:07 PM Revision 3314: mappings/VegX-VegBIEN.stems.csv: Removed locationevent.datasource_id mappings because locationevents are now scoped by their required location, which itself is scoped by datasource
- 08:42 PM Revision 3313: sql.py: distinct_table(): Don't sort the inserted rows by pkey because they should stay in the table order that they were in. (The select order with no ORDER BY should be the table order. Even if it isn't, it doesn't matter what order they are in for our current application.)
- 08:38 PM Revision 3312: sql_io.py: put_table(): Creating an empty pkeys table: Don't sort the inserted result by pkey because it's empty (limit=0)
- 08:32 PM Revision 3311: sql_io.py: put_table(): ignore(): Fixed bug where in_col's table needed to be changed to insert_in_table, because it's *insert_in_table's* rows that are being modified but mapping (which in_col comes from) qualifies columns by *in_table*
- 08:28 PM Revision 3310: sql_io.py: put_table(): ignore(): Also add an index on in_col if mapping the value to NULL
- 08:28 PM Revision 3309: sql_io.py: put_table(): ignore(): Only delete from the insert_in_table, because the invalid rows only need to be removed from the rows that are actually being inserted into the DB. If there are invalid rows in the full (not uniquified) in_table, that's OK, as they can still get a valid output pkey if the first copy of a row they were considered a duplicate of *is* valid (this is a very unusual situation, so this change should not affect most real data).
- 08:22 PM Revision 3308: sql_io.py: put_table(): ignore(): Merged filter_ var into sql.delete() call because that's the only place it's used
- 08:18 PM Revision 3307: sql_io.py: put_table(): insert_into_pkeys(): Removed no longer used distinct param
- 08:16 PM Revision 3306: sql_io.py: put_table(): Getting output table pkeys of existing/inserted rows: Don't DISTINCT ON the joined rows by input pkey, because this adds sorting overhead. This should not be needed because there generally should not be any duplicate rows for the columns in a unique index (if there are, this is an index configuration problem and should be fixed in the schema). It's possible that partial indexes (with a filter condition) were causing this, but testing without it in place will be needed to determine the cause.
- 08:02 PM Revision 3305: sql.py: flatten(): Auto-add a pkey on the created temp table. This should be standard practice for most temp tables, and for sql_io.put_table() especially this will be useful if we ever want to add back sorting the in_table by row_num (possibly by CLUSTERing on the pkey to avoid pkey index scans).
- 07:54 PM Revision 3304: sql.run_query_into() calls: Use new add_pkey_ param instead of manually calling sql.add_pkey()
- 07:53 PM Revision 3303: sql.py: run_query_into(): Changed add_indexes_ param to add_pkey_ and add just a pkey if it's set. It's no longer necessary to create indexes on every column of a temp table, because the covering indexes for the join columns have been fixed to have columns in the same order as the output table's corresponding index so that they can be used for a merge join.
- 07:41 PM Revision 3302: sql_io.py: put_table(): Add pkey on pkeys table right when it's created, so that any duplicates are detected right away instead of at the end of the iteration. (Duplicates are created as a result of joins matching multiple rows, which often indicates a database misconfiguration.)
- 07:34 PM Revision 3301: sql_io.py: put_table(): Adding pkey on pkeys table: Removed log message because adding an index is considered a low-level operation, which isn't included in the Redmine SQL
- 07:27 PM Revision 3300: schemas/tree_cross-links.sql: Ancestors table: Synced with current definition, which removes unneeded fki_* indexes. Note that the index on ancestor_id might be needed in the future if we ever want to get all the descendants of a plantname/namedplace or perform deletions on plantname/namedplace (which cascade to *_ancestor). For getting all the plantnames/namedplaces (of any rank) for a plantconcept/locationdetermination, though, the *_ancestor_pkey index is sufficient because plantname_id/namedplace_id is the first column in it.
- 07:20 PM Revision 3299: schemas/vegbien.sql: {plantname,namedplace}_update_ancestors(): Fixed slowdown due to removed index on {plantname,namedplace}.parent_id by adding COALESCE() to enable using the plantname_unique index for the lookup instead
- 06:26 PM Revision 3298: sql.mk_select() calls: Removed no longer needed start=0 to turn off missing WHERE, LIMIT, or OFFSET clause warning
- 06:21 PM Revision 3297: sql.py: mk_select(): Don't output warning if there is no WHERE, LIMIT, or OFFSET clause, because column-based import has many queries where this is the case and it's annoying to need to specify start=0 to turn off this warning
- 06:04 PM Revision 3296: sql.py: flatten(): Don't sort the input tables by the pkey because it doesn't matter what order the datasource's rows are inserted in. Note that PostgreSQL doesn't guarantee the order of rows in a table, so it is possible that the rows were being inserted in an unknown order before this change, as well.
- 05:58 PM Revision 3295: sql.py: delete(): Cache deletes by default
- 05:56 PM Revision 3294: sql_io.py: put_table(): Merged remove_rows() and invalid2null() into one ignore() function that chooses the action (map to NULL or delete) depending on the value and whether NULLs have been filtered out of the column
- 05:46 PM Revision 3293: sql_io.py: put_table(): remove_rows(): Delete the rows containing the invalid value instead of filtering them out of each select, so that the filtering can be profiled separately from the insertion. This also requires deleting rows with invalid non-NULL values instead of mapping them to NULL if NULLs have already been filtered out of the column in question.
- 05:34 PM Revision 3292: sql_io.py: put_table(): Main insert: Don't run it inside an extra savepoint, because this will cause the creation of any helper SQL functions to be rolled back if an exception is thrown. If those functions are later re-used, the cache will think they exist when they no longer do. (Calling a function on input rows is now run in recover mode, so that it doesn't need the outer savepoint anymore.)
- 05:30 PM Revision 3291: sql_io.py: put_table(): main_insert(): Moved code that is not part of the main query outside the function, so it wouldn't be subject to the exception handling. Preparing to insert new rows: Only do the preparation code for insert_select() if the out_table is not a function.
- 05:19 PM Revision 3290: sql_io.py: put_table(): main_insert(): is_function: Run insert_into_pkeys() with recover=True so that errors in the function are properly rolled back
- 05:18 PM Revision 3289: sql_io.py: put_table(): insert_into_pkeys(): Support custom query kw_args, such as recover
- 04:41 PM Revision 3288: sql_io.py: put_table(): Use full_in_table in the into table row count assertion, since in_table may have rows deleted
- 04:36 PM Revision 3287: sql_io.py: put_table(): Save default values for all rows in new temp table full_in_table since in_table may have rows deleted
- 04:13 PM Revision 3286: sql.py: Added mk_delete() and delete()
- 03:36 PM Revision 3285: sql_io.py: put_table(): mk_main_select(): Turned off unnecessary ORDER BY to avoid sorting the entire table every time it's used. (PostgreSQL has no concept of reordering a table and re-using that ordering, so it just re-sorts the table each time. Index scans on the pkey do not appear to be used in practice, according to EXPLAIN results from live imports.) Document that we instead assume that identical SELECT queries retrieve rows in the same order.
- 01:56 PM Revision 3284: schemas/vegbien.sql: taxondetermination: Fixed bug where taxondetermination_taxonoccurrence_id_fkey trigger was applied before the NOT NULL constraint on taxonoccurrence_id was checked, causing the trigger to fail on NULL taxonoccurrence_ids, by making it an AFTER trigger. (An AFTER trigger will still roll back the entire insert if it fails, even though it runs after the insert itself.)
07/09/2012
- 05:45 PM Revision 3283: schemas/vegbien.sql: specimenreplicate: institution_id: Fixed typo in comment
- 05:26 PM Revision 3282: inputs/import.stats.xls: Fixed date for most recent import
- 05:26 PM Revision 3281: sql.py: DbConn.run_query(): Put the data source comment on a separate line in the log file instead of using a carriage return, which sometimes had the desired effect of overwriting the src comment with the first line of the query but sometimes the line lengths weren't right and there wasn't enough overlap
- 04:53 PM Revision 3280: schemas/vegbien.ERD.mwb: Synced with schema
- 04:42 PM Revision 3279: schemas/vegbien.sql: Removed per-column indexes, which are no longer needed by either row-based or column-based import because they are able to do a merge join or lookup using the table's UNIQUE INDEX. Instead of forcing the database to build and maintain large indexes (15+ GB!) that are not used, optimization-only (non-UNIQUE) indexes should be added as needed only once the database is actually used for queries. In most cases it will not even be necessary to add additional indexes then, because most UNIQUE indexes can be reused for broad lookups (rather than just duplicate elimination). Even the foreign key covering indexes (fki_*) are not needed because we virtually never delete rows in the DB, and even if we were to start doing that regularly, the cost of maintaining the indexes on import is most likely not worth the speed improvements for cascading deletes.
- 04:32 PM Revision 3278: schemas/py_functions.sql: Removed per-column indexes on relational functions, which are no longer needed by row-based import because it is able to do a merge join-style lookup using the table's UNIQUE INDEX. (Note that column-based import doesn't use the (slower) relational functions at all anymore, and instead calls the corresponding SQL function directly using named arguments.)
- 04:31 PM Revision 3277: schemas/functions.sql: Removed per-column indexes on relational functions, which are no longer needed by row-based import because it is able to do a merge join-style lookup using the table's UNIQUE INDEX. (Note that column-based import doesn't use the (slower) relational functions at all anymore, and instead calls the corresponding SQL function directly using named arguments.)
- 04:26 PM Revision 3276: schemas/vegbien.sql: plantname: plantname_unique UNIQUE INDEX: Moved scope_id to the back so that the index can easily be used for lookup queries (not just column-based import) without having to explicitly specify NULL for that field. This takes advantage of a btree sorting feature where a broader lookup can be done using just the first n columns of the index.
- 04:15 PM Revision 3275: schemas/vegbien.sql: locationevent, specimenreplicate: Turned UNIQUE CONSTRAINTs and UNIQUE INDEXes with nullable fields into partial UNIQUE INDEXes with IS NOT NULL filter conditions, in order to work automatically with sql_gen without requiring a separate covering lookup index. Removed no longer needed covering lookup indexes.
- 03:07 PM Revision 3274: sql_io.py: put_table(): DuplicateKeyException: Fixed bug where combining multiple unique constraints was incorrectly allowed, when in fact the constraints need to be separately applied to the different rows that violate them, which is not currently supported
- 03:02 PM Revision 3273: sql.py: DbConn.with_savepoint(): Log transaction profiling info with level=4 like the rest of the transaction commands, so that it isn't output when the transaction itself should be hidden (e.g. for name versioning or internal commands)
- 02:16 PM Revision 3272: sql.py: DbConn.with_savepoint(): Profile (nested) transactions so that the run time for groups of commands (e.g. csv2db INSERTs) is known
- 02:04 PM Revision 3271: csv2db: verbosity defaults to 3 so that detailed queries with profiling stats are included in the log file, to assist in optimization
- 02:01 PM Revision 3270: csv2db: Don't cache per-row INSERT queries because this bloats the cache (there aren't repeated identical INSERTs that shouldn't be re-run like in row-based import)
- 01:57 PM Revision 3269: sql.py with_explain_comment(), DbConn: Fixed bug where with_explain_comment() was being run in per-row imports (row-based import and csv2db with INSERT), causing the overhead of an EXPLAIN query for every single INSERT and filling up the cache with EXPLAIN query results, by adding autoexplain mode, only running with_explain_comment() in autoexplain mode, and only enabling autoexplain mode for column-based import
- 01:11 PM Revision 3268: db_xml.py: put_table(): Turn on autoanalyze mode to help the query planner avoid sequential scans on tables that now contain data. (Don't do this in row-based import because it creates too much overhead per insert.)
- 12:24 PM Revision 3267: sql.py: Run all EXPLAIN queries with log_level=4 since the EXPLAIN information is now usually generated when the query is generated rather than when it's run, so the log_level is not known
- 12:21 PM Revision 3266: sql.py: Added with_explain_comment() to query generating functions so that nested queries will also have EXPLAIN information
- 12:11 PM Revision 3265: sql.py: Added with_explain_comment() and use it in run_query()
- 12:01 PM Revision 3264: sql.py: run_query(): EXPLAIN output: Run explain() with log_level 1 higher than the query's log_level, so that low-level queries' EXPLAIN queries are not output when the queries themselves are not output. This also ensures that only level 2 (major) queries have the EXPLAIN logged (to introduce the query that is being run), to avoid cluttering the log output.
- 11:54 AM Revision 3263: sql.py: explain(): Support custom log_level
- 11:48 AM Revision 3262: schemas/vegbien.sql: taxondetermination: taxondetermination_taxonoccurrence_id_fkey manual fkey constraint: Fixed bug where needed to raise foreign_key_violation instead of unique_violation
- 11:23 AM Revision 3261: inputs/import.stats.xls: Updated with stats from latest import
07/06/2012
- 04:43 PM Revision 3260: debug2redmine.csv: Remove newline before EXPLAIN comment
- 04:33 PM Revision 3259: debug2redmine.csv: Filter out EXPLAIN comments
- 04:29 PM Revision 3258: sql.py: run_query(): EXPLAIN all explainable queries before they are run, to provide query plans for later profiling and index analysis. At verbosity 3+, this also effectively allows the user to see what query is being run before it's executed.
- 04:26 PM Revision 3257: sql.py: is_explainable(): Fixed bug where needed r'' syntax to escape \ in \b
- 04:23 PM Revision 3256: sql.py: Added explain() and is_explainable()
- 04:19 PM Revision 3255: strings.py: Added join_lines()
- 02:50 PM Revision 3254: mk_rm_indexes: Also include the search_path in the outputted commands
- 02:45 PM Revision 3253: schemas/vegbien.sql: commclass: Fixed bug where commclass_unique needed to be a UNIQUE INDEX
- 02:42 PM Revision 3252: schemas/vegbien.sql: plantname: Removed unneeded indexes on plantname and rank (plantname_unique takes care of joins)
- 02:33 PM Revision 3251: pg_dump_vegbien: Enclose the schema name in "" because pg_dump requires this for schema names with special characters
- 02:09 PM Revision 3250: inputs/import.stats.xls: Updated with stats from 2012-7-3 and 2012-7-5 imports. Note that the 2012-7-5 import was partial, so its stats can't be directly compared.
- 01:28 PM Revision 3249: root Makefile: VegBIEN DB: Schemas: Added schemas/%/rm_indexes
- 01:27 PM Revision 3248: Added mk_rm_indexes
- 11:14 AM Revision 3247: sql.py: Added drop() and use it in drop_table()
- 10:59 AM Revision 3246: debug2redmine: Remove profiling information from the logging output
- 10:43 AM Revision 3245: sql.py: DbConn.run_query(): Only print notices in debug mode, because they are output with a log level higher than the debug verbosity threshold, and this avoid unnecessary overhead
- 10:41 AM Revision 3244: sql.py: DbConn: Added profile_row_ct setting, which is passed to profiler.stop() in run_query()
- 10:38 AM Revision 3243: bin/map: Logging: Raised debug-mode verbosity threshold to 1.5 so that in row-based imports, which have a default verbosity of 1.1, sql.DbConn.run_query() will not profile the query, to avoid unnecessary overhead
- 10:34 AM Revision 3242: sql.py: DbConn.run_query(): Only profile queries in debug mode, to avoid unnecessary overhead when the run time will not be displayed
- 10:29 AM Revision 3241: sql.py: DbConn.run_query(): Profile using the profiling.ItersProfiler class, which pretty-prints the run time
- 10:22 AM Revision 3240: sql.py: DbConn.run_query(): Added profiling of query execution, which is logged with the query
- 09:26 AM Revision 3239: sql.py: DbConn.run_query(): Move log_msg() to where it's used, so that it runs after the query is run and can refer to profiling variables
- 09:21 AM Revision 3238: sql.py: DbConn.run_query(): Use else blocks to avoid applying exception handling to commands run after the main command
- 09:18 AM Revision 3237: sql.py: DbConn.run_query(): Always output or return the log message after the query is run, so that it can be output with profiling statistics in the log message header
- 09:05 AM Revision 3236: sql.py: run_query(): Always output the log message after the query is run, so that it can be output with profiling statistics in the log message header
07/05/2012
- 03:16 PM Revision 3235: Regenerated vegbien.ERD exports
- 03:13 PM Revision 3234: schemas/vegbien.sql: locationevent: Added covering lookup indexes on the unique constraints to enable fast merge joins in column-based import. Removed no longer needed individual-column lookup indexes because the constraint-covering lookup indexes now handle lookups. This also avoids index bloat.
- 03:00 PM Revision 3233: schemas/vegbien.sql: specimenreplicate: Removed no longer needed individual-column lookup indexes because the constraint-covering lookup indexes now handle lookups. This also avoids index bloat.
- 02:57 PM Revision 3232: schemas/vegbien.sql: specimenreplicate: Added covering lookup indexes on the unique constraints to enable fast merge joins in column-based import
- 02:48 PM Revision 3231: schemas/vegbien.sql: specimenreplicate: Added CHECK constraint which ensures that there is at least one key to sufficiently uniquely identify the specimenreplicate
- 02:44 PM Revision 3230: inputs/CTFS/maps/VegX.organisms.csv: Mapped VegX sourceAccessionCode = VegBIEN plantobservation,specimenreplicate.sourceaccessioncode so that specimenreplicate would have a required key
- 02:38 PM Revision 3229: mappings/VegX-VegBIEN.stems.csv: Sort the plantobservation.sourceaccessioncode/specimenreplicate.sourceaccessioncode mapping with the other _ifs so the adjacent node merging works properly and it gets created before _ignore removes voucherType
- 02:34 PM Revision 3228: mappings/VegX-VegBIEN.stems.csv: Also map plantobservation.sourceaccessioncode to specimenreplicate.sourceaccessioncode so specimenreplicate always has a key and will never be underconstrained
- 02:12 PM Revision 3227: xml_func.py: process(): Fixed bug where an evaluated XML function might create a node of the same name as an existing node, but these nodes would not be merged even though they referred to the same object, by merging siblings of a newly-evaluated (replaced) node if they have the same name
- 02:09 PM Revision 3226: xml_dom.py: Added merge() and merge_adjacent()
- 02:08 PM Revision 3225: xml_dom.py: replace_with_text(): Return the new node
- 12:33 PM Revision 3224: mappings/VegX-VegBIEN.stems.csv: Indirect voucher mappings: Removed no longer needed ":[*_id/taxonoccurrence]" because a specimenreplicate *is* a taxonoccurrence, so it doesn't need to *have* an empty taxonoccurrence
- 12:27 PM Revision 3223: mappings/VegX-VegBIEN.stems.csv: Fixing specimenreplicate->taxonoccurrence mapping bug where taxonoccurrence_id is no longer used as an fkey because it's instead a pkey inherited from taxonoccurrence, by instead using the new fkey to plantobservation for direct vouchers. Note that a duplicate aggregateoccurrence is created, because the _if XML function runs after the XPaths have created the initial tree, and thus the nodes it pulls forward do not automatically get merged with adjacent nodes of the same name. This will eventually need to be fixed by auto-merging the nodes.
- 12:00 PM Revision 3222: schemas/vegbien.sql: specimenreplicate: Fixing specimenreplicate->taxonoccurrence mapping bug where taxonoccurrence_id is no longer used as an fkey because it's instead a pkey inherited from taxonoccurrence, by instead adding an fkey to plantobservation for direct vouchers. Also, it makes more sense for a specimenreplicate to directly voucher the plant it came from rather than that plant's taxonoccurrence, because a direct voucher is a closer relationship to the plant.
- 11:22 AM Revision 3221: mappings/VegX-VegBIEN.stems.csv: Map collectiondate to specimenreplicate via voucher when the voucher is indirect, rather than always directly to the taxonoccurrence, because the collectiondate relates to the specimenreplicate, not the taxonoccurrence, and is not necessarily 1:1 with it
- 11:17 AM Revision 3220: mappings: Updated for_review VegX-VegBIEN mappings, which hadn't been auto-updated because of a modification time issue. (mappings/VegX-VegBIEN.stems.csv was replaced with an older version, which did not trigger make to remake files depending on it.)
- 10:28 AM Revision 3219: schemas/vegbien.sql: locationevent: Added sql_gen-compatible indexes on all columns in the locationevent_unique_project_authorcode UNIQUE index: Changed locationevent_project_id index to use COALESCE(). Added index on obsstartdate.
- 10:19 AM Revision 3218: schemas/vegbien.sql: locationevent: Removed no longer needed COALESCE() index on location_id now that location_id is NOT NULL
- 10:16 AM Revision 3217: schemas/vegbien.sql: locationevent: Fixed bug where locationevent_unique_location index was overconstraining locationevent when a sourceaccessioncode or obsstartdate was specified, by combining the locationevent_unique_location, locationevent_unique_accessioncode, and locationevent_unique_location_date indexes into one COALESCE() index on the combined fields of those indexes
- 10:10 AM Revision 3216: schemas/vegbien.sql: locationevent: Made location_id required because every locationevent should have a location, even one with no locationdeterminations. This also avoids the creation of a parent locationevent when subplots are not being used.
- 09:48 AM Revision 3215: mappings/VegX-VegBIEN.stems.csv: Removed _collapse where it's no longer needed because sql_io.put() handles that now. Note that each locationevent will get an empty commclass, whether or not there are any commdeterminations. This can later be used to add new commdeterminations.
- 09:45 AM Revision 3214: schemas/vegbien.sql: commclass: Changed commclass_unique to COALESCE() classnotes so that there is only one commclass for a locationevent when the commclasses are not separately named. (Currently classnotes is used as the class name field, commname being the name of the community itself.)
- 09:33 AM Revision 3213: schemas/vegbien.sql: commdetermination: Made commconcept_id NOT NULL because it doesn't make sense to have a commdetermination on nothing. Note that the commname field in commdetermination is not used for making determinations (and may need to be removed to avoid confusion); commname.commname is used instead.
- 09:28 AM Revision 3212: schemas/vegbien.sql: locationevent: Added COALESCE() index on location_id for use by column-based import
- 09:24 AM Revision 3211: mappings/VegX-VegBIEN.stems.csv: Removed _collapse where it's no longer needed because sql_io.put() handles that now. Note that each plantobservation will get an empty stemobservation, whether or not there are any stemtags. This can later be used to add further stemtags.
- 08:58 AM Revision 3210: mappings/VegX-VegBIEN.stems.csv: Removed _collapse where it's no longer needed because sql_io.put() handles that now
- 08:31 AM Revision 3209: schemas/vegbien.sql: location: Made datasource_id, sourceaccessioncode NOT NULL to ensure that all locations are uniquely identifiable by their datasource's unique key (sourceaccessioncode)
- 08:28 AM Revision 3208: sql_io.py: put(): Handle NullValueExceptions by returning a NULL pkey, just like put_table() (column-based import) does
07/03/2012
- 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.
- 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.
- 03:15 PM Revision 3205: README.TXT: Data import: Import data into VegBIEN: Added command to use for column-based import
- 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
- 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.
- 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.
- 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
- 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
- 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.
- 07:40 AM Revision 3198: inputs/import.stats.xls: Updated with remaining stats from most recent import
07/02/2012
- 03:52 PM Revision 3197: PostgreSQL-MySQL.csv: Remove INHERITS clauses
- 02:37 PM Revision 3196: schemas/vegbien.ERD.mwb: Fixed lines
- 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
- 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.
- 01:58 PM Revision 3193: inputs/import.stats.xls: Updated with new stats from an independent import
- 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
- 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
- 12:30 PM Revision 3190: inputs/import.stats.xls: Updated with more stats from latest import
- 12:03 PM Task #426 (Resolved): Reload DB using column-based import
- Has been reloaded once, and is being reloaded again
- 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.
- 10:32 AM Revision 3188: input.Makefile: Documentation: import/steps.by_col.sql: Fixed bug where needed to run import in test mode
- 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
- 10:03 AM Revision 3186: bin/map: by_col: Reuse existing out_db connection for in_db instead of opening separate connection
- 09:50 AM Revision 3185: sql.py: mk_select(): Replaced newlines with spaces when query is simple enough to fit on one line
- 09:40 AM Revision 3184: db_xml.py: put_table(): Set db.src to help identify the data source in pg_stat_activity
- 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
- 09:38 AM Revision 3182: sql_gen.py: Added lstrip() to remove comments
- 09:13 AM Revision 3181: sql.py: mk_insert_select(): Added src param to help identify the data source in pg_stat_activity
- 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.
- 08:31 AM Revision 3179: input.Makefile: Prompt user to accept test, instead of providing command line func for doing so
- 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.
- 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
- 07:16 AM Revision 3176: inputs/import.stats.xls: Updated to include run times for rest of datasources for most recent column-based import
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
- 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)
- 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
- 07:41 AM Revision 3172: strings.py: Added first_word()
- 07:35 AM Revision 3171: sql_io.py: cast_temp_col(): Use sql_gen.suffixed_col() to create the new column name
- 06:16 AM Revision 3170: inputs/import.stats.xls: Added run time for SALVIAS organisms, which just finished
- 06:14 AM Revision 3169: inputs/import.stats.xls: Use [1]-style footnotes because copying and pasting to Gmail doesn't preserve the superscripts
- 06:11 AM Revision 3168: inputs/import.stats.xls: Updated for latest simultaneous column-based import
- 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()
- 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()
- 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
- 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.
- 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.
- 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.
- 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)
- 01:52 AM Revision 3160: sql.py: DbConn.with_savepoint(): Increment _savepoint before running queries so they don't get autocommitted
- 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.
- 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.
- 01:01 AM Revision 3157: util.py: dict_subset(): Use OrderedDict so that order of keys in input dict (if ordered) will be preserved
- 12:55 AM Revision 3156: main Makefile: python-Darwin: Added pip installation instructions. python-Linux: Added ordereddict.
- 12:04 AM Revision 3155: sql.py: DbConn.col_info(): cacheable param defaults to True now that callers explicitly turn off cacheable when needed
- 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()
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
- 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
- 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()
- 11:35 PM Revision 3150: sql.py: DbConn.col_info(): Allow caller to specify whether query is cacheable
- 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.
- 11:09 PM Revision 3148: sql.py: add_index(): Don't generate a unique name for the index because the database does that automatically
- 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)
- 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.)
- 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
- 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
- 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.
- 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
- 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.)
- 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)
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.
- 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.
- 10:12 PM Revision 3137: sql.py: DbConn.with_savepoint(): Open a new transaction if one is not already open
- 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
- 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
- 09:31 PM Revision 3134: csv2db: Create errors table first, so that imports can start using it right away
- 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
- 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
- 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
- 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
- 08:26 PM Revision 3129: sql.py: mk_select(): Also support limit and start values of type long
- 08:13 PM Revision 3128: sql_gen.py: suffixed_table(): Fixed bug where needed to copy *all* table attrs, such as is_temp status
- 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
- 07:50 PM Revision 3126: sql.py: create_table(): Removed final newline after query because that's added by the logging mechanism
- 07:43 PM Revision 3125: sql.py: Added reconnect()
- 07:37 PM Revision 3124: sql.py: DbConn._reset(): Assert that _savepoint is 0 instead of setting it to 0
- 07:31 PM Revision 3123: db_xml.py: put_table(): put_table_(): Removed no longer used limit, start params
- 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.
- 07:11 PM Revision 3121: db_xml.py: put_table(): Partitioning in_table: Adjust bounds of last partition to actual row #s included
- 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
- 06:41 PM Revision 3119: sql.py: DbConn.close(): Reset the connection completely using reset()
- 06:40 PM Revision 3118: sql.py: DbConn: Added clear_cache() and reset() and use reset() in __init__()
- 06:31 PM Revision 3117: bin/map: Use new DbConn.close()
- 06:31 PM Revision 3116: sql.py: DbConn: Added close()
- 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
- 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.
- 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.
- 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
- 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
- 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.
- 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
- 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
- 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)
- 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
- 03:12 PM Revision 3105: sql_gen.py: with_table(): Support columns that are wrapped in a FunctionCall object
- 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
06/26/2012
- 11:06 PM Revision 3103: Moved error tracking from sql.py to sql_io.py
- 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.
- 10:36 PM Revision 3101: sql_gen.py: suffixed_table(): Use concat()
- 10:34 PM Revision 3100: sql_gen.py: with_default_table(): Remove no longer used overwrite param
- 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
- 10:31 PM Revision 3098: sql_gen.py: Moved NamedCol check from with_default_table() to with_table()
- 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
- 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 "_".
- 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
- 08:46 PM Revision 3094: sql.py: Added distinct_table()
- 08:46 PM Revision 3093: sql_gen.py: Added with_table() and use it in with_default_table()
- 07:52 PM Revision 3092: sql.py: mk_insert_select(): ignore mode: Support inserting all columns when cols == None
- 07:47 PM Revision 3091: sql_gen.py: Col, Table: Support non-string names
- 07:25 PM Revision 3090: sql_gen.py: row_count: Use new all_cols
- 07:24 PM Revision 3089: sql_gen.py: Added all_cols
- 07:17 PM Revision 3088: sql_gen.py: Use new as_Name() instead of db.esc_name()
- 07:12 PM Revision 3087: sql_gen.py: Name: Truncate the input name
- 07:11 PM Revision 3086: sql_gen.py: Added Name class and associated functions
- 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().
- 06:33 PM Revision 3084: sql.py: Added copy_table_struct()
- 06:32 PM Revision 3083: sql.py: Moved add_indexes() to Indexes subsection
- 06:30 PM Revision 3082: sql.py: create_table(): Support LIKE table
- 05:18 PM Revision 3081: Moved Data cleanup from sql.py to sql_io.py
- 05:18 PM Revision 3080: Moved error tracking from sql.py to sql_io.py
- 05:12 PM Revision 3079: sql.py: Organized Database structure introspection and Structural changes functions into subsections
- 04:56 PM Revision 3078: Moved error tracking from sql.py to sql_io.py
- 04:46 PM Revision 3077: Moved Heuristic queries from sql.py to new sql_io.py
- 04:32 PM Revision 3076: Added top-level analysis dir for range modeling
- 04:02 PM Revision 3075: sql.py: run_query_into(): Documented why analyze() must be run manually on newly populated temp tables
- 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.
- 03:52 PM Revision 3073: sql.py: run_query_into(): analyze() the created table to ensure the query planner's initial stats are accurate
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
- 09:35 PM Revision 3071: cat_csv: Support overwriting the existing header using a separate header file
- 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
- 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
- 08:42 PM Revision 3068: sql.py: Added analyze()
- 08:11 PM Revision 3067: csv2db: Removed no longer needed table vacuum (cleanup_table() now avoids creating dead rows)
- 08:10 PM Revision 3066: sql.py: cleanup_table(): Use update()'s new in_place mode to avoid needing to vacuum the table
- 08:02 PM Revision 3065: sql.py: mk_update(): in_place: Support updating multiple columns at once
- 07:44 PM Revision 3064: sql.py: update() calls: Use in_place where possible to avoid creating dead rows, which bloats table size
- 07:37 PM Revision 3063: sql.py: DbConn.col_info(): Support user-defined types
- 07:33 PM Revision 3062: sql_gen.py: Added Nullif
- 07:27 PM Revision 3061: sql_gen.py: Added Coalesce class and use it in EnsureNotNull
- 07:15 PM Revision 3060: sql_gen.py: Added coalesce and use it in EnsureNotNull
- 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.
- 06:56 PM Revision 3058: sql.py: mk_update(): Implemented in_place mode
- 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
- 06:32 PM Revision 3056: sql.py: mk_update(): Added in_place param
- 06:13 PM Revision 3055: csvs.py: TsvReader: Prevent "new-line character seen in unquoted field" errors by replacing '\r' with '\n'
- 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_
- 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
- 02:45 PM Revision 3052: inputs/import.stats.xls: Updated for most recent run
