Analysis: Lengths which are not UNIV_SQL_NULL, but bigger than the following
number indicate that a field contains a reference to an externally
stored part of the field in the tablespace. The length field then
contains the sum of the following flag and the locally stored len.
This was incorrectly set to
define UNIV_EXTERN_STORAGE_FIELD (UNIV_SQL_NULL - UNIV_PAGE_SIZE_MAX)
When it should be
define UNIV_EXTERN_STORAGE_FIELD (UNIV_SQL_NULL - UNIV_PAGE_SIZE_DEF)
Additionally, we need to disable support for > 16K page size for
row compressed tables because a compressed page directory entry
reserves 14 bits for the start offset and 2 bits for flags.
This limits the uncompressed page size to 16k. To support
larger pages page directory entry needs to be larger.
A few tests assumes that the CYCLE timer is always available,
which is not true on some platforms (e.g. ARM).
Fixing the tests not to reply on the CYCLE availability.
ha_partition::init_record_priority_queue()
Cherry-pick rev.6b0ee0c795499cee7f9deb649fb010801e0be4c2 from mysql-5.6.
Bug #18305270 BACKPORT BUG#18694052 FIX
FOR ASSERTION `!M_ORDERED_REC_BUFFER'
FAILED TO 5.6
PROBLEM
-------
Missed to remove record priority queue if
init_index failed for a partition which
was causing the crash.
FIX
---
Remove priority queue if init_index fails
for partition.
Analysis: Current implementation will write and read at least one block
(sort_buffer_size bytes) from disk / index even if that block does not
contain any records.
Fix: Avoid writing / reading empty blocks to temporary files (disk).
Assertion `inited==INDEX' failed in int handler::ha_index_first(uchar*)
The crash was because errors from init_read_record_idx() was not taken care of.
(even when configured with --binlog-format=statement).
Before we got an error on the slave and the slave stopped if the master
was configured with --binlog-format=mixed or --binlog-format=row.
if we didn't write the CREATE TEMPORARY TABLE statement.
- Enable old code from one of my older changesets that didn't make into 10.0
- Fix test cased that failed as they expected DROP TEMPORARY TABLE in the log.
Analysis: When a page is read from encrypted table and page can't be
decrypted because of bad key (or incorrect encryption algorithm or
method) page was incorrectly left on buffer pool.
Fix: Remove page from buffer pool and from pending IO.
Added per-table boolean IETF_QUOTES variable to CSV storage engine. It allows to
enable IETF-compatible parsing of embedded quote and comma characters. Disabled
by default.
This patch is based on Percona revision:
b32fbf0276
Note that original patch adds server variable, while this patch adds per-table
variable.
The test restarts the server and expects that the feedback plugin
will send a report on shutdown, and will write about it in the error
log. But the server is only given 10 sec to shut down properly,
which is not always enough.
Added a parameter to restart_mysqld.inc, and set it to a bigger
value in feedback_plugin_send
The culprit is the feedback_plugin_load test, which is run both separately
and from inside feedback_plugin_send.test. The test queries I_S.FEEDBACK,
and every time it does, 'FEEDBACK used' value is increased.
Fixed by checking that the value is increased instead of recording the actual
value in the result file.
The real problem is that when innodb.xa_recovery test intentionally
crashes the server, system tables can be opened and marked as crashed,
and the next test in line gets blamed for the error which appears
in the error log.
Fixed by flushing the tables before crashing the server
