xpath.py: get(): Create attrs: Fixed bug where attrs were created with last_only on, which caused attrs to get created multiple times if there were multiple attrs of the same name but different values, becase the last_only optimization would only check the last attr of that name

mappings/DwC2-VegBIEN.specimens.csv: *Latitude/*Longitude: Use new _toDouble to convert strings to doubles (needed for by_col)

schemas/functions.sql: Added _toDouble

bin/map: When calling xml_func.process(), pass DB connection if available

xml_func.py: process(): If DB with relational functions available (passed in via db param), call any non-local XML functions as relational funcs

sql.py: put(): pkey param (now pkey_) defaults to table's pkey

bin/map: by_col: In debug mode, print stripped XML tree that guides import

vegbien_dest: Fixed bug where there was a missing line continuation char before schemas var

sql.py: DbConn: Fixed bug where schemas db_config value needed to be split apart into strings. Fixed bug where current_setting() returned a value rather than an identifier, so it had to be used with set_config() instead of SET, and run after SET TRANSACTION ISOLATION LEVEL. Moved Input validation section before Database connections because it's used by Database connections.

Regenerated vegbien.ERD exports

vegbien.ERD.mwb: Changed lines to a configuration that MySQLWorkbench wouldn't keep resetting whenever the ERD was reopened

vegbien_dest: Added "functions" to schemas

sql.py: db_config: Added schemas param. DbConn: Use any schemas db_config value to set search_path.

sql.py: add_row_num(): Name the column "_row_num" so that it doesn't conflict with any "row_num" column that's part of the table schema

main Makefile: VegBIEN DB: functions schema: Renamed schemas/functions/clear to .../reset to reflect that it also resets the schema to what's in the dump file. schemas/functions/reset: Use now-available schemas/functions.sql to create the schema.

Added autogen schemas/functions.sql

schemas/vegbien.sql.make: Use new pg_dump_vegbien

Added pg_dump_vegbien to dump a schema of the vegbien db

main Makefile: VegBIEN DB: Added functions schema targets

Makefile: $(confirm): Support a separate line outside of the highlighted line. Include the "Continue?" in the macro since all prompts include it.

Makefile: VegBIEN DB: Display different warning message depending on whether entire DB or just current public schema is being deleted

db_xml.py: put_table(): Recurse into forward pointers

sql.py: put_table(): Take multiple in_tables. Initial implementation just used the first in_table.

sql.py: Added add_row_num(). put_table(): Add row_num to pkeys_table, so it can be joined with in_table's pkeys.

sql.py: Added run_query_into() and use it in insert_select()

sql.py: pkey(): Support escaped table names

sql.py: mk_insert_select(): embeddable: Name the function alias "f" since it will just be wrapped in a nested SELECT, so the exact name doesn't matter (and won't be visible outside the nested SELECT anyway)

db_xml.py: put_table(): Return the (table, col) where the pkeys are made available, now that this information is available from sql.put_table()

sql.py: put_table(): Return just the name of the table where the pkeys are made available, since the column name in that table now equals the pkey name

sql.py: mk_insert_select(): embeddable: Make the column returned by the function have the same name as the returning column

db_xml.py: put_table() Use new sql.put_table()

sql.py: Added put_table()

sql.py: Added clean_name(). Use it where needed to make an escaped name appendable as a string.

sql.py: Added with_parsed_errors() and use it in try_insert()

sql.py: insert_select(): into != None: Fixed bug where cacheable was not passed through to DROP TABLE's run_query(), even though it was passed through to CREATE TABLE AS's run_query()

db_xml.py: put_table(): Place pkeys in temp table

sql.py: mk_insert_select(): Document that embeddable will cause the query to be fully cached, not just if it raises an exception. insert_select(): into != None: Pass recover and cacheable through to each run_query()

sql.py: insert_select(): Support placing RETURNING values in temp table

db_xml.py: put_table(): Support returning pkey from INSERT SELECT

sql.py: mk_insert_select(): Support using an INSERT RETURNING statement as a nested SELECT

sql.py: mk_insert_select(): Removed unused params recover and cacheable

sql.py: Added mogrify()

db_xml.py: put_table(): Corrected @return doc

sql.py: Added mk_insert_select() and use it in insert_select()

db_xml.py: put_table(): Use new insert_select()

sql.py: insert_select(): Changed order of cols and params arguments so select_query and params would be together

sql.py: Added insert_select() and use it in insert()

Calls to sql.esc_name*(): Removed preserve_case=True because it is now the default

sql.py: esc_name_by_module(): Changed preserve_case to ignore_case, which defaults to False

Calls to sql.esc_name*(): Removed preserve_case=True because it is now the default

sql.py: esc_name_by_module(): preserve_case defaults to True

sql.py: mk_select(): Escape all names used (table, column, cond, etc.)

sql.py: esc_name_by_module(): If not enclosing name in quotes, call check_name() on it

sql.py: mk_select(): Support literal values in the list of cols to select

sql.py: mk_select(): Don't escape the table name, because it will either be check_name()d or it's already been escaped

sql.py: Added mk_select(), and use it in select()

bin/map: Always pass qual_name(table) to sql.select(). This is possible now that qual_name() can handle None schemas.

db_xml.py: put_table(): Take separate in_table and in_schema names, instead of in_table and table_is_esc, because the in_schema is needed to scope the temp tables appropriately

sql.py: qual_name(): If schema is None, don't prepend schema

bin/map, sql.py: Turned SQL query caching back on because benchmarks of just the caching on vs. off reveal that it does reduce processing time significantly. However, there is a slowdown that was introduced between the time caching was added and the time the same XML tree was used for each node, which was giving the false indication that the slowdown was due to the caching.

bin/map: Turn SQL query caching off by default

bin/map: Added cache_sql env var to enable SQL query caching

sql.py: Make caching DbConn enablable. Turn caching off by default because recent benchmarks (n=1000) were showing that it slows things down.

bin/map: Added new verbose_errors mode, enabled in test mode and off otherwise, which controls whether the output row and tracebacks are included in error messages. Having this off in import mode will reduce the size of error logs so they don't fill up the vegbiendev hard disk as quickly.

exc.py: print_ex(): Added detail option to turn off traceback

bin/map: Turn parallel processing off by default. This should fix "Cannot allocate memory" errors in large imports.

bin/map: in_is_db: Don't cache the main SELECT query

bin/map: by_col: Use the created template, which already has the column names in it, instead of mapping a sample row

bin/map: Fixed bug where db_xml could not be imported twice, or it was treated as an undefined variable for some reason

bin/map: map_table(): Make each column a db_xml.ColRef instead of a bare index, so that it will appear as the column name when converted to a string. This will provide better debugging info in the template tree and also avoid needing to create a separate sample row in by_col.

db_xml.py: Added ColRef

bin/map: Fixed bug where row count was off by one if all rows in the input were exhausted, because the row that raises StopIteration was counting as a row

main Makefile: VegBIEN DB: mk_db: Use template1 because it has PROCEDURAL LANGUAGE plpgsql already installed and we aren't using an encoding other than UTF8

Moved "CREATE PROCEDURAL LANGUAGE plpgsql" to main Makefile so that it would only run when the DB is created, not when the public schema is reinstalled. This is only relevant on PostgreSQL < 9.x, where the plpgsql language is not part of template0.

Renamed parallel.py to parallelproc.py to avoid conflict with new system parallel module on vegbiendev

Makefile: VegBIEN DB: public schema: Added schemas/rotate

bin/map: Fixed bug in input rows processed count where the count would be off by 1, because the for loop would leave i at the index of the last row instead of one-past-the-last

bin/map: Use the same XML tree for each row in DB outputs, to eliminate time spent creating the tree from the XPaths for each row

bin/map: map_table(): Resolve each prefix into a separate mapping, which is collision-eliminated, instead of resolving values from multiple prefixes when each individual row is mapped

bin/map: Moved collision-prevention code to map_rows() so it would only run if there were mappings, and so that it would run after any mappings preprocessing by map_table() that creates more collisions

bin/map: Prevent collisions if multiple inputs mapping to same output

mappings/DwC1-DwC2.specimens.csv: Mapped collectorNumber and recordNumber to recordNumber with _alt so they wouldn't collide when every input column, even empty ones, are created in the XML tree

bin/map: If out_is_db, in debug mode, print each row's XML tree and each value that it's putting

bin/map: If out_is_db, in debug mode, print the template XML tree used to insert a sample row into the DB

bin/map: map_table(): When translating mappings to column indexes, use appends to a new list instead of deletions from an existing list to simplify the algorithm

union: Omit mappings that are mapped to in the input map, in addition to mappings that were overridden. This prevents multiple outputs being created for both the renamed and original mappings, causing duplicate output nodes when one XML tree is used for all rows.

union: Omit mappings that are mapped to in the input map, in addition to mappings that were overridden. This prevents multiple outputs being created for both the renamed and original mappings, causing duplicate output nodes when one XML tree is used for all rows.

input.Makefile: Maps building: Via maps cleanup: subtract: Include comment column so commented mappings are never removed

subtract: Support "ragged rows" that have fewer columns than the specified column numbers

util.py: list_subset(): Added default param to specify the value to use for invalid indexes (if any)

mappings/VegX-VegBIEN.stems.csv: Mappings with multiple inputs for the same output: Use _alt, etc. to map the multiple inputs to different places in the XML tree, so that when using a pregenerated tree, the empty leaves for each input will not collide with each other

mappings/VegX-VegBIEN.stems.csv: Changed XPath references (using "$") to XML function references using _ref where needed to make them work even on a pre-made XML tree used by all rows

xml_func.py: Added _ref to retrieve a value from another XML node

xml_func.py: Made all functions take a 2nd node param, which contains the func node itself

bin/map: If outputting to a DB, also create output XML elements for NULL input values. This will help with the transition to using the same XML tree for all rows.

xml_func.py: _label: return None on empty input

mappings/VegX-VegBIEN.stems.csv: Added _collapse around subtrees that need to be removed if they are created around a NULL value

xml_func.py: Added _collapse to collapse a subtree if the "value" element in it is NULL

schemas/vegbien.sql: definedvalue: Made definedvalue nullable so that each row of a datasource can have a uniform structure in VegBIEN, and to support reusing the same XML DOM tree for each row

xpath.py: Added is_xpath()
