This release repairs an issue in the test suite that would prevent the suite from passing on Python version 3.6.2. The release is made at the same time as that of release 1.0.18 and 1.2.0b2. Also included are fixes related to ORM use of JSON NULL values, subquery eager loading, and a stability enhancement involving the identity map when used under high concurrency.
- Fixed inconsistent state in externally closed connections
Was fixed in 2.6.2 but not included in 2.7 by mistake.
- Fixed Python exceptions propagation in green callback
- Don't display the password in `connection.dsn` when the connection
string is specified as an URI
- Return objects with timezone parsing "infinity" :sql:`timestamptz`
- Dropped dependency on VC9 runtime on Windows binary packages
- Fixed segfault in `~connection.lobject()` when *mode*\=\ `!None`
- Fixed `~connection.lobject()` keyword argument *lobject_factory*
- Fixed `~psycopg2.extras.ReplicationCursor.consume_stream()`
*keepalive_interval* argument
- Maybe fixed random import error on Python 3.6 in multiprocess
environment
- Fixed random `!SystemError` upon receiving abort signal
- Accept `~psycopg2.sql.Composable` objects in
`~psycopg2.extras.ReplicationCursor.start_replication_expert()`
- Parse intervals returned as microseconds from Redshift
- Added `~psycopg2.extras.Json` `!prepare()` method to consider connection
params when adapting
- `~psycopg2.errorcodes` map updated to PostgreSQL 10 beta 1.
- Fixed an error where Oracle sometimes truncated timestamp formats so
that date parsing failed. Thanks to Johann Wilfling for the report and
@nmaqsudov for the solution (#316).
- Added pager configuration, prioritizing the new `core.pager`
configuration variable over the `$PAGER` environment variable. The new
`$SQITCH_PAGER` environment variable trumps all. Thanks to Yati Sagade
for the pull request (#329).
- Documented the `core.editor` configuration variable.
- Updated PostgreSQL registry detection to avoid errors when not running
Sqitch as a superuser and the registry schema already exists. Done by
looking for the `changes` table in the `pg_tables` view instead of
looking for the registry schema in the `pg_namespace` catalog table,
and by using `CREATE SCHEMA IF NOT EXISTS` on PostgreSQL 9.3 and
higher. Thanks to @djk447 for the pull request (#307).
- Updated PostgreSQL registry detection to avoid errors when the `psql`
client is newer than the server version. Sqitch now fetches the version
from the server instead of parsing it from the client.
- Specifying a change before a target name on the command-line no longer
ignores the target (#281).
- The `--db-*` options are now more consistently applied to a target,
including when the target is specified as a URI (#293).
- `HEAD` and `ROOT` are now properly recognized as aliases for `@HEAD`
and `@ROOT`, when querying the database. This was supposedly done in
v0.991, but due to a bug, it wasn't really. Sorry about that.
- The `revert` and `verify` commands will now fail if a change is
specified and matches multiple changes. This happens when referencing a
reworked change only by its name. In this case, Sqitch will emit an
error listing properly tag-qualified changes to use. Suggested by Jay
Hannah (#312).
- Sqitch no longer returns an error when a target name is passed to a
command and the default target's plan file does not exist (#324).
- Added missing options to the `rework` usage statement. Thanks to Jay
Hannah for the PR (#342).
- Passing an engine name or plan file as the `<database>` parameter to
the `log`, `status`, and `upgrade` commands now works correctly,
matching what the documention has said for some time (#324).
- Added the `--target` option to the `plan` and `show` commands.
- Added the `<database>` parameter to the `plan` command.
- Sqitch now loads targets from all config files, not just the local
file, when trying to determine if a `<database>` parameter is a plan
file name.
- Improved the error message when a change is found more than once in a
plan, typically a reworked changed referenced only by name. The error
will no longer be "Key at multiple indexes", but "Change is ambiguous.
Please specify a tag-qualified change:", followed by a list of
tag-qualified variants of the change.
- Fixed a bug where the verify command would return a database error when
it finds no registory. Now it reports that the registry wasn't found in
the database.
* Standardize on JSON-based distribution (and remove ini-based distribution)
* Fix various (minor) bugs
* Overhaul docs
* Breaking change: json package info now in datapackage.json
* Security Fix: The linked OpenSSL library for the MySQL Commercial Server has been updated to version 1.0.2l. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html.
This change does not affect the Oracle-produced MySQL Community build of MySQL Server, which uses the yaSSL library instead.
Platform-Specific Notes
* Linux: The generic Linux build for MySQL 5.6 is now built on Oracle Linux 6 using glibc 2.12. Systems that use the build need to have glibc 2.12 or later installed on them.
Functionality Added or Changed
* For Windows, MSI installer packages now include a check for the required Visual Studio redistributable package, and produce a message asking the user to install it if it is missing.
* The mysql client now supports a --binary-as-hex option that causes display of binary data using hexadecimal notation (0xvalue). Thanks to Daniël van Eeden for the patch.
* mysqlaccess now looks for its configuration file only in the SYSCONFDIR directory and /etc.
Bugs Fixed
* InnoDB: The server allocated memory unnecessarily for an operation that rebuilt the table.
* InnoDB: When using an index merge optimizer switch, a SELECT COUNT(*) operation sometimes returned 0. Partitioning code incorrectly performed a memcpy instead of a column copy of columns read by the index, causing the wrong records to be copied.
* Replication: A USE statement that followed a SET GTID_NEXT statement sometimes had no effect.
* Replication: If the binary log on a master server was rotated and a full disk condition occurred on the partition where the binary log file was being stored, the server could stop unexpectedly. The fix adds a check for the existence of the binary log when the dump thread switches to next binary log file. If the binary log is disabled, all binary logs up to the current active log are transmitted to slave and an error is returned to the receiver thread.
* Replication: If a relay log index file named relay log files that did not exist, RESET SLAVE ALL sometimes did not fully clean up properly.
* Replication: mysqlbinlog, if invoked with the --raw option, does not flush the output file until the process terminates. But if also invoked with the --stop-never option, the process never terminates, thus nothing is ever written to the output file. Now the output is flushed after each event.
* Replication: A memory leak in mysqlbinlog was fixed. The leak happened when processing fake rotate events, or when using --raw and the destination log file could not be created. The leak only occurred when processing events from a remote server. Thanks to Laurynas Biveinis for his contribution to fixing this bug.
* Replication: Multi-threaded slaves could not be configured with small queue sizes using slave_pending_jobs_size_max if they ever needed to process transactions larger than that size. Any packet larger than slave_pending_jobs_size_max was rejected with the error ER_MTS_EVENT_BIGGER_PENDING_JOBS_SIZE_MAX, even if the packet was smaller than the limit set by slave_max_allowed_packet.
* With this fix, slave_pending_jobs_size_max becomes a soft limit rather than a hard limit. If the size of a packet exceeds slave_pending_jobs_size_max but is less than slave_max_allowed_packet, the transaction is held until all the slave workers have empty queues, and then processed. All subsequent transactions are held until the large transaction has been completed. The queue size for slave workers can therefore be limited while still allowing occasional larger transactions.
* mysqldump could write database names in USE statements incorrectly.
* If the mysql_stmt_close() C API function was called, it freed memory that later could be accessed if mysql_stmt_error(), mysql_stmt_errno(), or mysql_stmt_sqlstate() was called. To obtain error information after a call to mysql_stmt_close(), call mysql_error(), mysql_errno(), or mysql_sqlstate() instead.
* Queries could be cached incorrectly, leading to incorrect query results, under these circumstances: InnoDB table; rows are being inserted but have not yet been committed; a query uses the table as a base table in a derived table; the optimizer chooses to materialize the derived table.
* Man pages for a few utilities were missing from Debian/Ubuntu packages.
* The field-t unit test failed to run with AddressSanitizer enabled. Thanks to Laurynas Biveinis for the patch.
* Debian client packages were missing information about conflicts with native packages.
* The Perl path in #! lines at the beginning of Perl scripts has been adjusted to /usr/local/bin/perl for FreeBSD 11.
* The server exited abnormally attempting to access invalid memory.
* A race condition could occur for CREATE TABLE statements with DATA DIRECTORY or INDEX DIRECTORY clauses.
* MySQL compilation in different directories produced different builds to leakage of absolute paths into debug information and __FILE__.
* mysqld_failed to start the server if the --datadir option was specified with a relative path name.
* With read_only enabled, creation of non-TEMPORARY tables by non-SUPER users was permitted under certain conditions.
*Certain stored functions, if used in a query WHERE clause, could be handled using Index Condition Pushdown (which should not happen), resulting in a server exit.
* On x86 machines, the uint3korr() macro read 4 bytes of data instead of the intended 3 bytes.
* An assertion was raised during a fetch operation by the memcached plugin.
* Queries that contained UNION in a subquery and GROUP BY could return incorrect results.
* LOAD XML INFILE performance became noticeably slower when the XML file being read contained a great many spaces, such as those introduced by indenting or pretty-printing. Now all leading whitespace is trimmed from each such value before reading it into memory.
* Security Fix: The linked OpenSSL library for the MySQL Commercial Server has been updated to version 1.0.2l. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html.

The LDAP controls and extended operations (EXOP) has been merged upstream
with some modifications. The patches backports upstream code to php70
and php71, with additionnal EXOP REFRESH support that is missing for now.
* Use a modern PBR package

occurred more than once in the container.
HTTP Headers and URL query string require specific data structure: multidict.
It behaves mostly like a regular dict but it may have several values for the
same key and preserves insertion ordering.
renamed py-redis-py to py-redis
2.10.5
* Allow URL encoded parameters in Redis URLs. Characters like a "/" can
now be URL encoded and redis-py will correctly decode them.
* Added support for the WAIT command.
* Better shutdown support for the PubSub Worker Thread. It now properly
cleans up the connection, unsubscribes from any channels and patterns
previously subscribed to and consumes any waiting messages on the socket.
* Added the ability to sleep for a brief period in the event of a
WatchError occuring.
* Fixed a bug with pipeline error reporting when dealing with characters
in error messages that could not be encoded to the connection's
character set.
* Fixed a bug in Sentinel connections that would inadvertantly connect
to the master when the connection pool resets.
* Better timeout support in Pubsub get_message.
* Fixed a bug with the HiredisParser that would cause the parser to
get stuck in an endless loop if a specific number of bytes were
delivered from the socket. This fix also increases performance of
parsing large responses from the Redis server.
* Added support for ZREVRANGEBYLEX.
* ConnectionErrors are now raised if Redis refuses a connection due to
the maxclients limit being exceeded.
* max_connections can now be set when instantiating client instances.

2017-06-29 Patrick Galbraith, Michiel Beijen, DBI/DBD community (4.043)
YOUR ATTENTION PLEASE, THIS IS A REVERT TO 4.041
This version is the same as 4.041 with all its bugs and
limitations. In version 4.042 there were some changes to Unicode handling
that turned out to be causing issues with existing implementations.
While it is possible to argue that the old behaviour was wrong and buggy,
lots of applications and scripts were depending on this behaviour so it
is NOT a good idea to change this.
There were lots of commits since 4.041, we'll add those back bit by bit
in a future release, excluding the ones which cause problems.
2017-??-?? Patrick Galbraith, Michiel Beijen, DBI/DBD community (4.042_01)
* Use Devel::CheckLib 1.09 or newer, fixes
https://github.com/perl5-dbi/DBD-mysql/issues/109

* Specify bigint as test dependency.
2017-03-08 Patrick Galbraith, Michiel Beijen, DBI/DBD community (4.042)
* Full release to include development releases 4.041_2 and 4.041_1.
2017-02-28 Patrick Galbraith, Michiel Beijen, DBI/DBD community (4.041_2)

Reported by Larry Leszczynski, fixed by Pali Roh獺r.
(https://rt.cpan.org/Public/Bug/Display.html?id=110983)
* Fix parsing configure libs from mysql_config --libs output in Makefile.PL
Libraries in mysql_config --libs output can be specified by library name
with the -l prefix or by absolute path to library name without any prefix.
Parameters must start with a hyphen, so treat all options without leading
hyphen in mysql_config --libs output as libraries with full path.

* Fix support for magic scalars (pali)
(https://github.com/perl5-dbi/DBD-mysql/pull/76)
2016-12-12 Patrick Galbraith, Michiel Beijen, DBI/DBD community (4.041_1)
* Unicode fixes: when using mysql_enable_utf8 or mysql_enable_utf8mb4,
previous versions of DBD::mysql did not properly encode input statements
to UTF-8 and retrieved columns were always UTF-8 decoded regardless of the
column charset.
Fix by Pali Roh獺r.
Reported and feedback on fix by Marc Lehmann

orm
[orm] [bug] Fixed issue with subquery eagerloading which continues on from the series of issues fixed in 2699, 3106, 3893 involving that the “subquery” contains the correct FROM clause when beginning from a joined inheritance subclass and then subquery eager loading onto a relationship from the base class, while the query also includes criteria against the subclass. The fix in the previous tickets did not accommodate for additional subqueryload operations loading more deeply from the first level, so the fix has been further generalized.
sql
[sql] [bug] Fixed AttributeError which would occur in WithinGroup construct during an iteration of the structure.
postgresql
[postgresql] [bug] Continuing with the fix that correctly handles Postgresql version string “10devel” released in 1.1.8, an additional regexp bump to handle version strings of the form “10beta1”. While Postgresql now offers better ways to get this information, we are sticking w/ the regexp at least through 1.1.x for the least amount of risk to compatibility w/ older or alternate Postgresql databases.
[postgresql] [bug] Fixed bug where using ARRAY with a string type that features a collation would fail to produce the correct syntax within CREATE TABLE.
mysql
[mysql] [bug] MySQL 5.7 has introduced permission limiting for the “SHOW VARIABLES” command; the MySQL dialect will now handle when SHOW returns no row, in particular for the initial fetch of SQL_MODE, and will emit a warning that user permissions should be modified to allow the row to be present.
mssql
[mssql] [bug] Fixed bug where SQL Server transaction isolation must be fetched from a different view when using Azure data warehouse, the query is now attempted against both views and then a NotImplemented is raised unconditionally if failure continues to provide the best resiliency against future arbitrary API changes in new SQL Server versions.
[mssql] [bug] Added a placeholder type mssql.XML to the SQL Server dialect, so that a reflected table which includes this type can be re-rendered as a CREATE TABLE. The type has no special round-trip behavior nor does it currently support additional qualifying arguments.
oracle
[oracle] [bug] Support for two-phase transactions has been removed entirely for cx_Oracle when version 6.0b1 or later of the DBAPI is in use. The two- phase feature historically has never been usable under cx_Oracle 5.x in any case, and cx_Oracle 6.x has removed the connection-level “twophase” flag upon which this feature relied.
