Notable changes since 3.2:
- Improve ways to write change migrations, making the old up & down
methods no longer necessary.
- Adds PostgreSQL array type support. Any datatype can be used to
create an array column, with full migration and schema dumper
support.
- Add Relation#load to explicitly load the record and return self.
- Model.all now returns an ActiveRecord::Relation, rather than an
array of records. Use Relation#to_a if you really want an array. In
some specific cases, this may cause breakage when upgrading.
- Added ActiveRecord::Migration.check_pending! that raises an error if
migrations are pending.
- Added custom coders support for ActiveRecord::Store.
- mysql and mysql2 connections will set SQL_MODE=STRICT_ALL_TABLES by
default to avoid silent data loss. This can be disabled by
specifying strict: false in your database.yml.
- Remove IdentityMap.
- Remove automatic execution of EXPLAIN queries. The option
active_record.auto_explain_threshold_in_seconds is no longer used
and should be removed.
- Adds ActiveRecord::NullRelation and ActiveRecord::Relation#none
implementing the null object pattern for the Relation class.
- Added create_join_table migration helper to create HABTM join
tables.
- Allows PostgreSQL hstore records to be created.
- Default scopes are no longer overridden by chained conditions.
- Added ActiveRecord::Base.to_param for convenient "pretty" URLs
derived from a model's attribute or method.
- Added ActiveRecord::Base.no_touching, which allows ignoring touch on
models.
- Unify boolean type casting for MysqlAdapter and
Mysql2Adapter. type_cast will return 1 for true and 0 for false.
- .unscope now removes conditions specified in default_scope.
- Added ActiveRecord::QueryMethods#rewhere which will overwrite an
existing, named where condition.
- Extended ActiveRecord::Base#cache_key to take an optional list of
timestamp attributes of which the highest will be used.
- Added ActiveRecord::Base#enum for declaring enum attributes where
the values map to integers in the database, but can be queried by
name.
- Type cast json values on write, so that the value is consistent with
reading from the database.
- Type cast hstore values on write, so that the value is consistent
with reading from the database.
- Make next_migration_number accessible for third party generators.
- Calling update_attributes will now throw an ArgumentError whenever
it gets a nil argument. More specifically, it will throw an error if
the argument that it gets passed does not respond to to
stringify_keys.
- CollectionAssociation#first/#last (e.g. has_many) use a LIMITed
query to fetch results rather than loading the entire collection.
- inspect on Active Record model classes does not initiate a new
connection. This means that calling inspect, when the database is
missing, will no longer raise an exception.
- Removed column restrictions for count, let the database raise if the
SQL is invalid.
- Rails now automatically detects inverse associations. If you do not
set the :inverse_of option on the association, then Active Record
will guess the inverse association based on heuristics.
- Handle aliased attributes in ActiveRecord::Relation. When using
symbol keys, ActiveRecord will now translate aliased attribute names
to the actual column name used in the database.
- The ERB in fixture files is no longer evaluated in the context of
the main object. Helper methods used by multiple fixtures should be
defined on modules included in
ActiveRecord::FixtureSet.context_class.
- Don't create or drop the test database if RAILS_ENV is specified
explicitly.
- Relation no longer has mutator methods like #map! and
#delete_if. Convert to an Array by calling #to_a before using these
methods.
- find_in_batches, find_each, Result#each and Enumerable#index_by now
return an Enumerator that can calculate its size.
- scope, enum and Associations now raise on "dangerous" name
conflicts.
- second through fifth methods act like the first finder.
- Make touch fire the after_commit and after_rollback callbacks.
- Enable partial indexes for sqlite >= 3.8.0.
- Make change_column_null revertible.
- Added a flag to disable schema dump after migration. This is set to
false by default in the production environment for new applications.
- SchemaDumper uses force: :cascade on create_table. This makes it
possible to reload a schema when foreign keys are in place.
- Added a :required option to singular associations, which defines a
presence validation on the association.
- ActiveRecord::Dirty now detects in-place changes to mutable
values. Serialized attributes on Active Record models are no longer
saved when unchanged. This also works with other types such as
string columns and json columns on PostgreSQL.
- Introduced the db:purge Rake task to empty the database for the
current environment.
- Introduced ActiveRecord::Base#validate! that raises
ActiveRecord::RecordInvalid if the record is invalid.
- Introduced validate as an alias for valid?.
- touch now accepts multiple attributes to be touched at once.
- The PostgreSQL adapter now supports the jsonb datatype in PostgreSQL
9.4+.
- The PostgreSQL and SQLite adapters no longer add a default limit of
255 characters on string columns.
- Added support for the citext column type in the PostgreSQL adapter.
- Added support for user-created range types in the PostgreSQL
adapter.
- sqlite3:///some/path now resolves to the absolute system path
/some/path. For relative paths, use sqlite3:some/path
instead. (Previously, sqlite3:///some/path resolved to the relative
path some/path. This behavior was deprecated on Rails 4.1).
- Added support for fractional seconds for MySQL 5.6 and above.
- Added ActiveRecord::Base#pretty_print to pretty print models.
- ActiveRecord::Base#reload now behaves the same as m =
Model.find(m.id), meaning that it no longer retains the extra
attributes from custom SELECTs.
- ActiveRecord::Base#reflections now returns a hash with string keys
instead of symbol keys.
- The references method in migrations now supports a type option for
specifying the type of the foreign key (e.g. :uuid).

Bug #12917164 DROP USER CAN'T DROP USERS WITH LEGACY
UPPER CASE HOST NAME ANYMORE
Description:
It is not possible to drop users with host names with upper case
letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing
with error.
Analysis: Since the fix 11748570 we came up with lower case hostnames
as standard. But in the current bug the hostname is created by
mysql_install_db script is still having upper case hostnames.
So, if we have the hostname with upper case letters like(Tmp_Host_Name)
then we will have as it is stored in the mysql.user table.
In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives
error because we do compare with the lower case of hostname since the
11748570 fix.
Fix: We need to convert the hostname to lower case before storing into
the mysql.user table when we run the mysql_install_db script.

-----
Security Notes
The mysql_options() C API function now supports a
MYSQL_OPT_SSL_MODE option. The only permitted option value is
SSL_MODE_REQUIRED, to require a secure connection to the server. It
causes mysql_real_connect() to fail if an encrypted connection cannot
be obtained, without falling back to an unencrypted connection. Thus,
mysql_real_connect() returns an error if the server does not support
SSL or the client is not configured to use SSL. The client/server
exchange terminates immediately after the initial server packet has
been received if the server indicates that it does not support SSL.
To require an encrypted connection in MySQL 5.5, the standard MySQL
client programs call mysql_options() to set MYSQL_OPT_SSL_MODE if the
--ssl-mode=REQUIRED command-line option was specified. Third-party
applications that must be able to require encrypted connections can
use the same technique. For details, see mysql_ssl_set().
The minor C API version number was not incremented for this
change. Application programs compiled for MySQL 5.5 that require
MYSQL_OPT_SSL_MODE may fail to operate properly if the dynamic loader
provides an older client library without MYSQL_OPT_SSL_MODE. Such
applications must be written to handle this possibility by checking
whether the mysql_options() call succeeds or fails. (Bug #25575605)

A continuing stream of small regressions is leading us to have to put out releases every few days at the moment. This release includes a fix to a regression that was caused by a fix to a regression :), specifically the sqlalchemy.ext.mutable fix put out in 1.1.8. It also fixes a different regression in the typing system introduced in 1.1.5, and also has a regular bug fix for another issue regarding "connectionless" execution.
2009.07.21: I hereby place the cdb package (in particular, cdb-
0.75.tar.gz, with MD5 checksum 81fed54d0bde51b147dd6c20cdb92d51) into
the public domain. The package is no longer copyrighted.
Added the PRAGMA optimize command
The SQLite version identifier returned by the sqlite_source_id() SQL function and the sqlite3_sourceid() C API and found in the SQLITE_SOURCE_ID macro is now a 64-digit SHA3-256 hash instead of a 40-digit SHA1 hash.
Added the json_patch() SQL function to the JSON1 extension.
Enhance the LIKE optimization so that it works for arbitrary expressions on the left-hand side as long as the LIKE pattern on the right-hand side does not begin with a digit or minus sign.
Added the sqlite3_set_last_insert_rowid() interface and use the new interface in the FTS3, FTS4, and FTS5 extensions to ensure that the sqlite3_last_insert_rowid() interface always returns reasonable values.
Enhance PRAGMA integrity_check and PRAGMA quick_check so that they verify CHECK constraints.
Enhance the query plans for joins to detect empty tables early and halt without doing unnecessary work.
Enhance the sqlite3_mprintf() family of interfaces and the printf SQL function to put comma separators at the thousands marks for integers, if the "," format modifier is used in between the "%" and the "d" (example: "%,d").
Added the -DSQLITE_MAX_MEMORY=N compile-time option.
Added the .sha3sum dot-command and the .selftest dot-command to the command-line shell
Begin enforcing SQLITE_LIMIT_VDBE_OP. This can be used, for example, to prevent excessively large prepared statements in systems that accept SQL queries from untrusted users.
Various performance improvements.
Bug Fixes:
----------
Ensure that indexed expressions with collating sequences are handled correctly. Fix for ticket eb703ba7b50c1a5.
Fix a bug in the 'start of ...' modifiers for the date and time functions. Ticket 6097cb92745327a1
Fix a potential segfault in complex recursive triggers, resulting from a bug in the OP_Once opcode introduced as part of a performance optimization in version 3.15.0. Ticket 06796225f59c057c
In the RBU extension, add extra sync operations to avoid the possibility of corruption following a power failure.
The sqlite3_trace_v2() output for nested SQL statements should always begin with a "--" comment marker.
* /dbfsak/VERSION, /dbfsak/dbf.c, /dbfsak/dbf.h, /dbfsak/dbfsak.c:
More precisely specify variable sizes, since DBF files were
originally 8-bit, then 16-bit, then 32-bit. Current code being
worked on 64 bit platform.

* gdbm_fetch, gdbm_firstkey, and gdbm_nextkey behavior
If the requested key was not found, these functions return datum with
dptr pointing to NULL and set gdbm_errno to GDBM_ITEM_NOT_FOUND (in
prior releases, gdbm_errno was set to GDBM_NO_ERROR),
If an error occurred, dptr is set to NULL, and gdbm_errno to
the error code.
In any case gdbm_errno is guaranteed to have meaningful value upon
return.
* Error handling
In previous versions of GDBM, fatal errors (such as write error while
storing the key/data pair or bucket) caused immediate termination of
the program via call to exit(3). This is no longer the case.
Starting from this version, if a fatal error occurrs while modifying
the database file, that database is marked as needing recovery and
gdbm_errno is set to GDBM_NEED_RECOVERY. Calls to any GDBM functions,
except gdbm_recover, will then return immediately with the same error
code.
The function gdbm_recover examines the database file and fixes
eventual inconsistencies. Upon successful return it clears the error
state and makes the database operational again.
For backward compatibility, the fatal_func argument to gdbm_open is
retained and its functionality is not changed. If it is not NULL, the
new error handling procedures are disabled, the function it points to
will be called upon fatal errors. When it returns, exit(1) will be
called.
* Per-database error codes
In addition to gdbm_error global variable, the most recent error state
is saved in the GDBM_FILE structure. This facilitates error handling
when operating multiple GDBM databases simultaneously.

What's new in psycopg 2.7
-------------------------
New features:
- Added `~psycopg2.sql` module to generate SQL dynamically (🎫`#308`).
- Added :ref:`replication-support` (🎫`#322`). Main authors are
Oleksandr Shulgin and Craig Ringer, who deserve a huge thank you.
- Added `~psycopg2.extensions.parse_dsn()` and
`~psycopg2.extensions.make_dsn()` functions (🎟️`#321, #363`).
`~psycopg2.connect()` now can take both *dsn* and keyword arguments, merging
them together.
- Added `~psycopg2.__libpq_version__` and
`~psycopg2.extensions.libpq_version()` to inspect the version of the
``libpq`` library the module was compiled/loaded with
(🎟️`#35, #323`).
- The attributes `~connection.notices` and `~connection.notifies` can be
customized replacing them with any object exposing an `!append()` method
(🎫`#326`).
- Adapt network types to `ipaddress` objects when available. When not
enabled, convert arrays of network types to lists by default. The old `!Inet`
adapter is deprecated (🎟️`#317, #343, #387`).
- Added `~psycopg2.extensions.quote_ident()` function (🎫`#359`).
- Added `~connection.get_dsn_parameters()` connection method (🎫`#364`).
- `~cursor.callproc()` now accepts a dictionary of parameters (🎫`#381`).
- Give precedence to `!__conform__()` over superclasses to choose an object
adapter (🎫`#456`).
- Using Python C API decoding functions and codecs caching for faster
unicode encoding/decoding (🎫`#473`).
- `~cursor.executemany()` slowness addressed by
`~psycopg2.extras.execute_batch()` and `~psycopg2.extras.execute_values()`
(🎫`#491`).
- Added ``async_`` as an alias for ``async`` to support Python 3.7 where
``async`` will become a keyword (🎫`#495`).
- Unless in autocommit, do not use :sql:`default_transaction_*` settings to
control the session characteristics as it may create problems with external
connection pools such as pgbouncer; use :sql:`BEGIN` options instead
(🎫`#503`).
- `~connection.isolation_level` is now writable and entirely separated from
`~connection.autocommit`; added `~connection.readonly`,
`~connection.deferrable` writable attributes.
Bug fixes:
- Fixed error caused by missing decoding `~psycopg2.extras.LoggingConnection`
(🎫`#483`).
- Fixed integer overflow in :sql:`interval` seconds (🎫`#512`).
Other changes:
- Dropped support for Python 2.5 and 3.1.
- Dropped support for client library older than PostgreSQL 9.1 (but older
server versions are still supported).
- `~connection.isolation_level` doesn't read from the database but will return
`~psycopg2.extensions.ISOLATION_LEVEL_DEFAULT` if no value was set on the
connection.
- Empty arrays no more converted into lists if they don't have a type attached
(🎫`#506`)
5.2.2
- The request circuit breaker, which track the size of in-flight
requests, was not decrementing its counter when the connection was
closed by the client before the response could be returned. This could
result in no further requests being accepted until the node has been
restarted. All users should upgrade to take advantage of this bug fix.
- The cgroup functionality (for reading OS stats for containers) had a
bug in the regex for parsing /proc/self/cgroup which prevented nodes
with multiple hierarchies from starting up.
- Requests which have been delayed by a shard lock might be executed
later on a different thread which lacks the request context, resulting
in the requests being incorrectly rejected as unauthorised.
- Removal of an undocumented syntax for include/exclude parameters in
the terms aggregation broke certain aggregations in Kibana.
5.2.1
- When stored fields are configured with best_compression, we rely on
JVM garbage collection to reclaim Deflater/Inflater instances. However
these classes use little JVM memory but may use significant native
memory, so if may happen that the OS runs out of native memory before
the JVM collects these unreachable Deflater/Inflater instances.
- Certain queries can hold a reference to the IndexReader that was used
to build them. When these queries are cached, this reference causes
Lucene to hold onto segments long after they should have been deleted.
Features

(PYTHON-640)
- NoHostAvailable or OperationTimedOut when using execute_concurrent
with a generator that inserts into more than one table (PYTHON-642)
- ResponseFuture creates Timers and don't cancel them even when result
is received which leads to memory leaks (PYTHON-644)
- Driver cannot connect to Cassandra version > 3 (PYTHON-646)
- Unable to import model using UserType without setuping connection
since 3.7 (PYTHON-649)
- Don't prepare queries on ignored hosts on_up (PYTHON-669)
- Sockets associated with sessions not getting cleaned up on
session.shutdown() (PYTHON-673)

- Resolve warnings in documentation generation (PYTHON-645)
- Cython dependency (PYTHON-686)
- Drop Support for Python 2.6 (PYTHON-690)
5.2.0 (2017-02-12)
- The client now automatically sends Content-Type http header set
to application/json. If you are explicitly passing in other
encoding than json you need to set the header manually.
