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.

schemas/vegbien.sql: specimenreplicate: Added covering lookup indexes on the unique constraints to enable fast merge joins in column-based import

schemas/vegbien.sql: specimenreplicate: Added CHECK constraint which ensures that there is at least one key to sufficiently uniquely identify the specimenreplicate

inputs/CTFS/maps/VegX.organisms.csv: Mapped VegX sourceAccessionCode = VegBIEN plantobservation,specimenreplicate.sourceaccessioncode so that specimenreplicate would have a required key

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

mappings/VegX-VegBIEN.stems.csv: Also map plantobservation.sourceaccessioncode to specimenreplicate.sourceaccessioncode so specimenreplicate always has a key and will never be underconstrained

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

xml_dom.py: Added merge() and merge_adjacent()

xml_dom.py: replace_with_text(): Return the new node

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

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.

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.

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

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.)

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.

schemas/vegbien.sql: locationevent: Removed no longer needed COALESCE index on location_id now that location_id is NOT NULL

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

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.

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.

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.)

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.

schemas/vegbien.sql: locationevent: Added COALESCE index on location_id for use by column-based import

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.

mappings/VegX-VegBIEN.stems.csv: Removed _collapse where it's no longer needed because sql_io.put() handles that now

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)

sql_io.py: put(): Handle NullValueExceptions by returning a NULL pkey, just like put_table() (column-based import) does

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&gt;, 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.

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.

README.TXT: Data import: Import data into VegBIEN: Added command to use for column-based import

schemas/vegbien.sql: locationevent: Allow a locationevent to be uniquely specified by its location (which is now datasource-scoped) and start date

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&gt;, 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.

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.

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

schemas/filter_ERD.csv: Add back taxondetermination->taxonoccurrence fkey because that has been replaced by a trigger in the SQL

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&gt;, 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.

inputs/import.stats.xls: Updated with remaining stats from most recent import

PostgreSQL-MySQL.csv: Remove INHERITS clauses

schemas/vegbien.ERD.mwb: Fixed lines

db_xml.py: put_table(): Moved in_row_ct updating to Subsetting section so the cursor's rowcount can be used directly

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.

inputs/import.stats.xls: Updated with new stats from an independent import

schemas/vegbien.sql: Fixed UNIQUE INDEXes that were still using COALESCE to use COALESCE in order to match what sql_gen.EnsureNotNull uses

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

inputs/import.stats.xls: Updated with more stats from latest import

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.

input.Makefile: Documentation: import/steps.by_col.sql: Fixed bug where needed to run import in test mode

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

bin/map: by_col: Reuse existing out_db connection for in_db instead of opening separate connection

sql.py: mk_select(): Replaced newlines with spaces when query is simple enough to fit on one line

db_xml.py: put_table(): Set db.src to help identify the data source in pg_stat_activity

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

sql_gen.py: Added lstrip() to remove comments

sql.py: mk_insert_select(): Added src param to help identify the data source in pg_stat_activity

mappings/DwC2-VegBIEN.specimens.csv: Mapped institutionCode. This will enable datasources to use specimenreplicate's institution_id index for duplicate elimination.

input.Makefile: Prompt user to accept test, instead of providing command line func for doing so

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.

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

inputs/import.stats.xls: Updated to include run times for rest of datasources for most recent column-based import

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

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)

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

strings.py: Added first_word()

sql_io.py: cast_temp_col(): Use sql_gen.suffixed_col() to create the new column name

inputs/import.stats.xls: Added run time for SALVIAS organisms, which just finished

inputs/import.stats.xls: Use [1]-style footnotes because copying and pasting to Gmail doesn't preserve the superscripts

inputs/import.stats.xls: Updated for latest simultaneous column-based import

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()

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()

sql.py: Removed no longer needed add_index_col() and ensure_not_null() because we are not using index columns

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.

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.

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.

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)

sql.py: DbConn.with_savepoint(): Increment _savepoint before running queries so they don't get autocommitted

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.

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.

util.py: dict_subset(): Use OrderedDict so that order of keys in input dict (if ordered) will be preserved

main Makefile: python-Darwin: Added pip installation instructions. python-Linux: Added ordereddict.

sql.py: DbConn.col_info(): cacheable param defaults to True now that callers explicitly turn off cacheable when needed

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()

sql.py: mk_update(): Renamed cacheable param to cacheable_ so it wouldn't conflict with update()'s cacheable param

sql.py: mk_update(): Added cacheable param to set whether column structure information used to generate the query can be cached

sql.py: add_index_col(): Explicitly set col_info()'s caching depending on whether col_info will be changed later by add_not_null()

sql.py: DbConn.col_info(): Allow caller to specify whether query is cacheable

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.

sql.py: add_index(): Don't generate a unique name for the index because the database does that automatically

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)

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.)

db_xml.py: partition_size: Turning partitioning back on (with a larger limit), since the largest datasources' temp tables are still too big

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

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.

db_xml.py: put_table(): Subsetting in_table: Truncate in_table when finished with it, to avoid temp table disk space leaks

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.)

top-level map: Added support for custom public schema, to be able to run imports and tests simultaneously (e.g. on a dev machine)

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.

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.

sql.py: DbConn.with_savepoint(): Open a new transaction if one is not already open

sql.py: DbConn: _savepoint starts at 1 because the driver is not in autocommit mode, so a transaction is already open

sql.py: DbConn: _savepoint starts at 1 because the driver is not in autocommit mode, so a transaction is already open

csv2db: Create errors table first, so that imports can start using it right away
