Fix an assertion associated with aggregate function processing that was incorrectly triggered by the push-down optimization.
This release incorporates the following changes:
* Add support for Postgres 13
* Add provisional support for Postgres 14
* Upgrade Jquery library to 3.4.1 (Nirgal)
* Allow users to see group owned databases when using "owned only"
* Fix bug where sorting on selects dumped you to the table screen (MichaMEG)
* This release drops support for PHP 7.1
* This will be the last release to support PHP 7.
Release 7.12.1 incorporated the following changes:
* Fix a number of issues related to changes in Postgres 12.
* Fix an issue with truncation of long multibyte strings
* Removal of broken tree branches from table/view browse option
* Properly escape identifiers when browsing tables/views/schemas

Finally, release 5.6 added support for all recent versions of Postgres (at
least 9.3 - 12devel). It also fixed a number of minor bugs and included several
language fixes.
changes in version 3.35.3
Enhance the OP_OpenDup opcode of the bytecode engine so that it works even if the cursor being duplicated itself came from OP_OpenDup. Fix for ticket bb8a9fd4a9b7fce5. This problem only came to light due to the recent MATERIALIZED hint enhancement.
When materializing correlated common table expressions, do so separately for each use case, as that is required for correctness. This fixes a problem that was introduced by the MATERIALIZED hint enhancement.
Fix a problem in the filename normalizer of the unix VFS.
Fix the "box" output mode in the CLI so that it works with statements that returns one or more rows of zero columns (such as PRAGMA incremental_vacuum). Forum post afbbcb5b72.
Improvements to error messages generated by faulty common table expressions. Forum post aa5a0431c99e.
Fix some incorrect assert() statements.
Fix to the SELECT statement syntax diagram so that the FROM clause syntax is shown correctly. Forum post 9ed02582fe.
Fix the EBCDIC character classifier so that it understands newlines as whitespace. Forum post 58540ce22dcd.
Improvements the xBestIndex method in the implementation of the (unsupported) wholenumber virtual table extension so that it does a better job of convincing the query planner to avoid trying to materialize a table with an infinite number of rows.

Release Notes for Samba 4.13.7
March 24, 2021
==============================
This is a follow-up release to depend on the correct ldb version. This is only
needed when building against a system ldb library.
This is a security release in order to address the following defects:
o CVE-2020-27840: Heap corruption via crafted DN strings.
o CVE-2021-20277: Out of bounds read in AD DC LDAP server.
=======
Details
=======
o CVE-2020-27840:
An anonymous attacker can crash the Samba AD DC LDAP server by sending easily
crafted DNs as part of a bind request. More serious heap corruption is likely
also possible.
o CVE-2021-20277:
User-controlled LDAP filter strings against the AD DC LDAP server may crash
the LDAP server.
For more details, please refer to the security advisories.
Changes since 4.13.6
--------------------
o Release with dependency on ldb version 2.2.1.
3.14.4
This release contains an important fix for a regression introduced by commit
ebe3ad5, which affected the way model instances are converted to parameters for
use in expressions within a query. The bug could manifest when code uses model
instances as parameters in expressions against fields that are not
foreign-keys.
Changes in version 3.35.2:
Fix a problem in the appendvfs.c extension that was introduced into version 3.35.0.
Ensure that date/time functions with no arguments (which generate responses that depend on the current time) are treated as non-deterministic functions. Ticket 2c6c8689fb5f3d2f
Fix a problem in the sqldiff utility program having to do with unusual whitespace characters in a virtual table definition.
Limit the new UNION ALL optimization described by item 8c in the 3.35.0 release so that it does not try to make too many new subqueries. See forum thread 140a67d3d2 for details.
3.35.1:
Fix a bug in the new DROP COLUMN feature when used on columns that are indexed and that are quoted in the index definition.
Documentation improvements.
OpenLDAP 2.4.58
Fixed slapd validity checks for issuerAndThisUpdateCheck
Fixed slapd to alloc new conn struct after freeing old one
Fixed slapd syncrepl to check all contextCSNs
Fixed slapd-bdb lockdetect config
SQLite Release 3.35.0 On 2021-03-12
Added built-in SQL math functions(). (Requires the -DSQLITE_ENABLE_MATH_FUNCTIONS compile-time option.)
Added support for ALTER TABLE DROP COLUMN.
Generalize UPSERT:
Allow multiple ON CONFLICT clauses that are evaluated in order,
The final ON CONFLICT clause may omit the conflict target and yet still use DO UPDATE.
Add support for the RETURNING clause on DELETE, INSERT, and UPDATE statements.
Use less memory when running VACUUM on databases containing very large TEXT or BLOB values. It is no longer necessary to hold the entire TEXT or BLOB in memory all at once.
Add support for the MATERIALIZED and NOT MATERIALIZED hints when specifying common table expressions. The default behavior was formerly NOT MATERIALIZED, but is now changed to MATERIALIZED for CTEs that are used more than once.
The SQLITE_DBCONFIG_ENABLE_TRIGGER and SQLITE_DBCONFIG_ENABLE_VIEW settings are modified so that they only control triggers and views in the main database schema or in attached database schemas and not in the TEMP schema. TEMP triggers and views are always allowed.
Query planner/optimizer improvements:
Enhancements to the min/max optimization so that it works better with the IN operator and the OP_SeekScan optimization of the previous release.
Attempt to process EXISTS operators in the WHERE clause as if they were IN operators, in cases where this is a valid transformation and seems likely to improve performance.
Allow UNION ALL sub-queries to be flattened even if the parent query is a join.
Use an index, if appropriate, on IS NOT NULL expressions in the WHERE clause, even if STAT4 is disabled.
Expressions of the form "x IS NULL" or "x IS NOT NULL" might be converted to simply FALSE or TRUE, if "x" is a column that has a "NOT NULL" constraint and is not involved in an outer join.
Avoid checking foreign key constraints on an UPDATE statement if the UPDATE does not modify any columns associated with the foreign key.
Allow WHERE terms to be pushed down into sub-queries that contain window functions, as long as the WHERE term is made up of entirely of constants and copies of expressions found in the PARTITION BY clauses of all window functions in the sub-query.
CLI enhancements:
Enhance the ".stats" command to accept new arguments "stmt" and "vmstep", causing prepare statement statistics and only the virtual-machine step count to be shown, respectively.
Add the ".filectrl data_version" command.
Enhance the ".once" and ".output" commands so that if the destination argument begins with "|" (indicating that output is redirected into a pipe) then the argument does not need to be quoted.
Bug fixes:
Fix a potential NULL pointer dereference when processing a syntactically incorrect SELECT statement with a correlated WHERE clause and a "HAVING 0" clause. (Also fixed in the 3.34.1 patch release.)
Fix a bug in the IN-operator optimization of version 3.33.0 that can cause an incorrect answer.
Fix incorrect answers from the LIKE operator if the pattern ends with "%" and there is an "ESCAPE '_'" clause.
3.14.3
This release contains a single fix for ensuring NULL values are inserted when
issuing a bulk-insert of heterogeneous dictionaries which may be missing
explicit NULL values.
Update php-redis to latest version 5.3.3, switch php-redis for php56 to
php73 and php74.
Changes are too many to write here, but php-redis supports redis 6.

Redis 6.2.0 GA Released Tue Feb 22 14:00:00 IST 2021
================================================================================
Upgrade urgency: SECURITY if you use 32bit build of redis (see bellow), MODERATE
if you used earlier versions of Redis 6.2, LOW otherwise.
Integer overflow on 32-bit systems (CVE-2021-21309):
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk
input size. By default, it is 512MB which is a safe value for all platforms.
If the limit is significantly increased, receiving a large request from a client
may trigger several integer overflow scenarios, which would result with buffer
overflow and heap corruption.
Bug fixes:
* Avoid 32-bit overflows when proto-max-bulk-len is set high
* Fix broken protocol in client tracking tracking-redir-broken message
* Avoid unsafe field name characters in INFO commandstats, errorstats, modules
* XINFO able to access expired keys during CLIENT PAUSE WRITE
* Fix allowed length for REPLCONF ip-address, needed due to Sentinel's support for hostnames
* Fix broken protocol in redis-benchmark when used with -a or --dbnum
* XADD counts deleted records too when considering switching to a new listpack
Bug fixes that are only applicable to previous releases of Redis 6.2:
* Fixes in GEOSEARCH bybox (accuracy and mismatch between width and height)
* Fix risk of OOM panic in HRANDFIELD, ZRANDMEMBER commands with huge negative count
* Fix duplicate replicas issue in Sentinel, needed due to hostname support
* Fix Sentinel configuration rewrite
Command behavior changes:
* SRANDMEMBER uses RESP3 array type instead of set type
* EXPIRE, EXPIREAT, SETEX, GETEX: Return error when provided expire time overflows
Other behavior changes:
* Remove ACL subcommand validation if fully added command exists.
Improvements:
* Optimize sorting in GEORADIUS / GEOSEARCH with COUNT
* Optimize HRANDFIELD and ZRANDMEMBER case 4 when ziplist encoded
* Optimize in-place replacement of elements in HSET, HINCRBY, LSET
* Remove redundant list to store pubsub patterns
* Add --insecure option to command line tools
Info fields and introspection changes:
* Add INFO fields to track progress of BGSAVE, AOFRW, replication
Modules:
* RM_ZsetRem: Delete key if empty, the bug could leave empty zset keys
* RM_HashSet: Add COUNT_ALL flag and set errno

Redis 6.2 RC2 Released Tue Jan 12 16:17:20 IST 2021
================================================================================
Upgrade urgency LOW: This is the second Release Candidate of Redis 6.2.

Redis 6.2 RC1 Released Mon Dec 14 11:50:00 IST 2020
================================================================================
Upgrade urgency LOW: This is the first Release Candidate of Redis 6.2.
Introduction to the Redis 6.2 release
=====================================
This release is the first significant Redis release managed by the core team
under the new project governance model.
Redis 6.2 includes many new commands and improvements, but no big features. It
mainly makes Redis more complete and addresses issues that have been requested
by many users frequently or for a long time.
Many of these changes were not eligible for 6.0.x for several reasons:
1. They are not backward compatible, which is always the case with new or
extended commands (that cannot be replicated to an older replica).
2. They require a longer release-candidate test cycle.
New commands / args:
* Add SMISMEMBER command that checks multiple members
* Add ZMSCORE command that returns an array of scores
* Add LMOVE and BLMOVE commands that pop and push arbitrarily
* Add RESET command that resets client connection state
* Add COPY command that copies keys
* Add ZDIFF and ZDIFFSTORE commands
* Add ZINTER and ZUNION commands
* Add GEOSEARCH/GEOSEARCHSTORE commands for bounding box spatial queries
* Add GET parameter to SET command, for more powerful GETSET
* Add exclusive range query to XPENDING
* Add exclusive range query to X[REV]RANGE
* Add GT and LT options to ZADD for conditional score updates
* Add CLIENT INFO and CLIENT LIST for specific ids
* Add IDLE argument to XPENDING command
* Add local address to CLIENT LIST, and a CLIENT KILL filter.
* Add NOMKSTREAM option to XADD command
* Add command introspection to Sentinel
* Add SENTINEL MYID subcommand
New features:
* Dump payload sanitization: prevent corrupt payload causing crashes
Has flags to enable full O(N) validation (disabled by default).
* ACL patterns for Pub/Sub channels
* Support ACL for Sentinel mode
* Support getting configuration from both stdin and file at the same time
Lets you avoid storing secrets on the disk.
New features in CLI tools:
* redis-cli RESP3 push support
* redis-cli cluster import support source and target that require auth
* redis-cli URIs able to provide user name in addition to password
* redis-cli/redis-benchmark allow specifying the prefered ciphers/ciphersuites
* redis-cli add -e option to exit with code when command execution fails
Command behavior changes:
* EXISTS should not alter LRU
In Redis 5.0 and 6.0 it would have touched the LRU/LFU of the key.
* OBJECT should not reveal logically expired keys
Will now behave the same TYPE or any other non-DEBUG command.
* Improve db id range check for SELECT and MOVE
Changes the error message text on a wrong db index.
* Modify AUTH / HELLO error message
Changes the error message text when the user isn't found or is disabled.
* BITOPS length limited to proto_max_bulk_len rather than 512MB
The limit is now configurable like in SETRANGE, and APPEND.
* GEORADIUS[BYMEMBER] can fail with -OOM if Redis is over the memory limit
Other behavior changes:
* Optionally (default) fail to start if requested bind address is not available
If you rely on Redis starting successfully even if one of the bind addresses
is not available, you'll need to tune the new config.
* Limit the main db dictionaries expansion to prevent key eviction
In the past big dictionary rehashing could result in massive data eviction.
Now this rehashing is delayed (up to a limit), which can result in performance
loss due to hash collisions.
* CONFIG REWRITE is atomic and safer, but requires write access to the config file's folder
This change was already present in 6.0.9, but was missing from the release
notes.
* A new incremental eviction mechanism that reduces latency on eviction spikes
In pathological cases this can cause memory to grow uncontrolled and may require
specific tuning.
* Not resetting "save" config when Redis is started with command line arguments.
In case you provide command line arguments without "save" and count on it
being disabled, Now the defaults "save" config will kick in.
* Update memory metrics for INFO during loading
* When "supervised" config is enabled, it takes precedence over "daemonize".
* Assertion and panic, print crash log without generating SIGSEGV
* Added crash log report on SIGABRT, instead of silently exiting
* Disable THP (Transparent Huge Pages) if enabled
If you deliberately enabled it, you'll need to config Redis to keep it.
Bug fixes:
* Handle output buffer limits for module blocked clients
Could result in a module sending reply to a blocked client to go beyond the
limit.
* Fix setproctitle related crashes.
Caused various crashes on startup, mainly on Apple M1 chips or under
instrumentation.
* A module doing RM_Call could cause replicas to get nested MULTI
* Backup/restore cluster mode keys to slots map for repl-diskless-load=swapdb
In cluster mode with repl-diskless-load, when loading failed, slot map
wouldn't have been restored.
* Fix oom-score-adj-values range, and bug when used in config file
Enabling setting this in the config file in a line after enabling it, would
have been buggy.
* Reset average ttl when empty databases
Just causing misleading metric in INFO
* Disable rehash when Redis has child process
This could have caused excessive CoW during BGSAVE, replication or AOFRW.
* Further improved ACL algorithm for picking categories
Output of ACL GETUSER is now more similar to the one provided by ACL SETUSER.
* Fix bug with module GIL being released prematurely
Could in theory (and rarely) cause multi-threaded modules to corrupt memory.
* Fix cluster redirect for module command with no firstkey.
* Reduce effect of client tracking causing feedback loop in key eviction
* Kill disk-based fork child when all replicas drop and 'save' is not enabled
* Rewritten commands (modified for propagation) are logged as their original command
* Fix cluster access to unaligned memory (SIGBUS on old ARM)
* If diskless repl child is killed, make sure to reap the child pid
* Broadcast a PONG message when slot's migration is over, may reduce MOVED responses
Other improvements:
* TLS Support in redis-benchmark
* Accelerate diskless master connections, and general re-connections
* Run active defrag while blocked / loading
* Performance and memory reporting improvement - sds take control of its internal fragmentation
* Speedup cluster failover.
Platform / toolchain support related improvements:
* Optionally (not by default) use H/W Monotonic clock for faster time sampling
* Remove the requirements for C11 and _Atomic supporting compiler
This would allow to more easily build and use Redis on older systems and
compilers again.
* Fix crash log registers output on ARM.
* Raspberry build fix.
* Setting process title support for Haiku.
* DragonFlyBSD RSS memory sampling support.
New configuration options:
* Enable configuring OpenSSL using the standard openssl.cnf
* oom-score-adj-values config can now take absolute values (besides relative ones)
* TLS: Add different client cert support.
* Note that a few other changes listed above added their config options.
Info fields and introspection changes:
* Add INFO fields to track diskless and disk-based replication progress
* Add INFO field for main thread cpu time, and scrape system time.
* Add total_forks to INFO STATS
* Add maxclients and cluster_connections to INFO CLIENTS
* Add tracking bcast flag and client redirection in client list
* Fixed INFO client_recent_max_input_buffer includes argv array
* Note that a few other changes listed above added their info fields.
Module API changes:
* Add CTX_FLAGS_DENY_BLOCKING as a unified the way to know if blocking is allowed
* Add data type callbacks for lazy free effort, and unlink
* Add data type callback for COPY command
* Add callbacks for defrag support.
* Add module event for repl-diskless-load swapdb
Module related fixes:
* Moved RMAPI_FUNC_SUPPORTED so that it's usable
* Improve timer accuracy
* Allow '\0' inside of result of RM_CreateStringPrintf
Rails 6.1.3 (February 17, 2021)
[ActionPack]
* Re-define routes when not set correctly via inheritance.
*John Hawthorn*
[ActiveRecord]
* Fix the MySQL adapter to always set the right collation and charset
to the connection session.
*Rafael Mendonça França*
* Fix MySQL adapter handling of time objects when prepared statements
are enabled.
*Rafael Mendonça França*
* Fix scoping in enum fields using conditions that would generate
an IN clause.
*Ryuta Kamizono*
* Skip optimised #exist? query when #include? is called on a relation
with a having clause
Relations that have aliased select values AND a having clause that
references an aliased select value would generate an error when
#include? was called, due to an optimisation that would generate
call #exists? on the relation instead, which effectively alters
the select values of the query (and thus removes the aliased select
values), but leaves the having clause intact. Because the having
clause is then referencing an aliased column that is no longer
present in the simplified query, an ActiveRecord::InvalidStatement
error was raised.
An sample query affected by this problem:
Author.select('COUNT(*) as total_posts', 'authors.*')
.joins(:posts)
.group(:id)
.having('total_posts > 2')
.include?(Author.first)
This change adds an addition check to the condition that skips the
simplified #exists? query, which simply checks for the presence of
a having clause.
Fixes#41417
*Michael Smart*
* Increment postgres prepared statement counter before making a
prepared statement, so if the statement is aborted without Rails
knowledge (e.g., if app gets kill -9d during long-running query or
due to Rack::Timeout), app won't end up in perpetual crash state for
being inconsistent with Postgres.
