MySQL Bug#71095: Wrong results with PARTITION BY LIST COLUMNS()
MySQL Bug#72803: Wrong "Impossible where" with LIST partitioning
MDEV-6240: Wrong "Impossible where" with LIST partitioning
- Backprot the fix from MySQL Bug#71095.
- When traversing JOIN_TABs with first_linear_tab/next_linear_tab(), don't forget
to enter the semi-join nest when it is the first table in the join order.
Failure to do so could cause e.g. I_S tables not to be filled.
GOES AWAY, MYSQL QUITS WORKING.
Analysis:
-----------------
Issue in this bug and in bug 11907705 is, the socket file or
fifo file is set for general log at command line while starting
the server. But currently, only regular file can be set for the
general log. Instead of reporting any error, the provided files
are opened for writing and continued. Because of this issues
mentioned in the bug reports are seen.
As mentioned, only when any non-regular file is set for general
log at command line while starting the server, these issues are
seen. If general log file is set to non-regular file from CLI
using system variable general_log_file then error is reported.
These issues can also be faced with slow query log file, if it is
set to non-regular file.
Fix:
-----------------
Currently while starting the server if we fail to open log file
then we report an error, disable logging to file and continue.
To fix issue reported code is modified to check whether file
is regular file or not before opening it. If file is not a
regular file then error is logged to error log and logging to
file is disabled.
If one uses 4 --verbose to mysql_upgrade it will also write out all mysqlcheck commands invoked.

A new command line option "galera-sst-mode" was introduced
in mysqldump as part of fix for MDEV-6316. But, since the
fix was pushed to maria-10.0-galera branch, the mysqldump
tool supplied with mariadb client deb/rpm packages, does not
have this new opion.
This fix contains the same patch along with a test case.
Remove the "don't update the row for b'' and store uninitialized bytes on disk" change.
Update test cases to allow DEFAULT b'', because b'' is a valid expression elsewhere.
Reason for the problem was that the hash of changed files in the key cache was too small (was 128). Fixed by making the hash size larger and changeable.
- Introduced key-cache-file-hash-size (default 512) for MyISAM and aria_pagecache_file_hash_size (default 512) for Aria.
- Added new status variable "Feature_delay_key_write" which counts number of tables opened that are using delay_key_write

The bug was that my_real_read() called net_before_header_psi() multiple times for long packets.
Fixed by adding a flag when we are reading a header.
Did also some cleanups to interface of my_net_read() to avoid unnecessary calls if performance schema is not used.
- Added my_net_read_packet() as a replacement for my_net_read(). my_net_read() is still in the client library for old clients.
- Removed THD->m_server_idle (not needed anymore as this is now given as argument to my_net_read_packet()
- Added my_net_read_packet(), which is a new version of my_net_read() with a new parameter if we are doing a read for a new command from the server.
- Added tests for compressed protocol and big packets

Merge the patches into MariaDB 10.0 main.
With this patch, parallel replication will now automatically retry a
transaction that fails due to deadlock or other temporary error, same as
single-threaded replication.
We catch deadlocks with InnoDB transactions due to enforced commit order. If
T1 must commit before T2 in parallel replication and T1 ends up waiting for T2
inside InnoDB, we kill T2 and retry it later to resolve the deadlock
automatically.
- In print_explain_row(), do not forget to print r_rows.
- Switch Explain_update from using its own counters to re-using
Table_access_tracker.
- Make ANALYZE UPDATE code structure uniform with ANALYZE DELETE.
MDEV-6344: mysqldump issues FLUSH TABLES, which gets written into binlog and replicated
Add a --gtid option (for compatibility, the original behaviour is preserved
when --gtid is not used).
With --gtid, --master-data and --dump-slave output the GTID position (the
old-style file/offset position is still output, but commented out). Also, a
CHANGE MASTER TO master_use_gtid=slave_pos is output to ensure a provisioned
slave is configured in GTID, as requested.
Without --gtid, the GTID position is still output, if available, but commented
out.
Also fix MDEV-6344, to avoid FLUSH TABLES getting into the binlog. Otherwise a
mysqldump on a slave server will silently inject a GTID which does not exist
on the master, which is highly undesirable.
Also fix an incorrect error handling around obtaining binlog position with
--master-data (was probably unlikely to trigger in most cases).
