Extra fix: 'if (p5 < p5_a + P5A_MAX)' is not portable.
p5 starts out pointing to a static array, then may point
to a buffer on the stack, then may point to malloc()ed memory.
The problem occurred when indexes are added between the time that an
UNDO record is created and the time that the purge thread comes around
and deletes the old secondary index entries. The purge thread would
hit an assert when trying to build a secondary index entry for
searching. The problem was that the old value of those fields were not
in the UNDO record since they were not part of an index when the UPDATE
occured.
A test case was added to innodb-index.test.

WITH MYSQL_REFRESH()
reset_slave_info.all was not initialized.
We fix this by setting lex->reset_slave_info.all= false in
the lex_start routine, which is called before every statement.
Added options --boot-gdb etc.
Extended gdb_arguments() with optional input argument
Cannot use set args in gdb init file, as run < <input> kills them (?)
For some reason the test authentication plugin accepted connection with arbitrary password. But the intention of the plugin is that password should equal to the authentication string and in the later versions of the server connection fails if password is wrong. So I have updated auth_rpl test to specify the correct password.
FULLTEXT INDEXES
myisamchk may create incorrect fulltext index for compressed
tables. Incorrect data pointer size was used while creating
fulltext index.
(also 5.5+ solution for bug#11766879/bug#60106)
The valgrind warning was due to an unused 'new handler_add_index(...)'
which was never freed.
The error handling did not work (fails as in bug#11766879) and
the implementation was not as transparant as it could, therefore I
made it a bit simpler and more transparant to the underlying handlers.
This way it follows the api better and the error handling works and
is also now tested.
Also added a debug test to verify the error handling.
Improved according to Jon Olavs review:
Added class ha_partition_add_index.
Also added base class Sql_alloc to handler_add_index.
Update 3.
Quick fix: run mysql-stress-test.pl via a wrapper test
Amend mtr to run just that test when using --stress
Updated mysql-stress-test.pl to exit(1) if wrong options
Followup fixes for --ps-protocol:
1) Incorrectly set ps_protocol variable instead of ps_protocol_enabled
2) disable_result_log was tested after calling handle_no_error()
which would revert a temporary setting.
Amendment to previous patch:
Failure in CONV() should return NULL instead of
empty set.
When compiled on Windows or Solaris the function
Item_func_conv::val_str() doesn't fail on
longlong2str() but finds an earlier exit path
based on the attributes of the arguments.
This exit path returns NULL on failure and as a
consequence the original patch caused different
test results depending on the OS used.
Connection of slave to master using a replication account which authenticates
with an external plugin was not possible.
Fixed by making sure that the CLIENT_PLUGIN_AUTH capability is set when client connects using mysql_real_connect(). Also, a plugin-dir path used by client library to locate authentication plugins is set based on the analogous server setting. This is done in connect_to_master() function before a call to mysql_real_connect().
Call handle_error() instead of die() when evaluating these
Must remember "current command" with link to errors to ignore
Added test cases to mysqltest.test
Added a keyword ONCE to add to those commands
Some internal tables to keep track of which properties are
temporarily overriden
Added tests in mysqltest.test
Updates to other tests will be done later
when buffered changes are to be discarded
sync_thread_add_level(level = SYNC_IBUF_INDEX_TREE): Relax a too strict
condition that the thread must not be holding locks below SYNC_FSP_PAGE.
It is perfectly valid to hold any latch above SYNC_IBUF_INDEX_TREE when
acquiring the insert buffer tree latch.
Please exclude make_binary_distribution from the distribution
With cmake (5.5 and up), "make package" will do it,
or cpack.
The (generated) "scripts/make_binary_distribution" is just
a wrapper around a "cpack" call,
with path names set at build time.
Similar, "make_win_bin_dist" is not needed any more.
when buffered changes are to be discarded
ibuf_add_free_page(): Lower the latching order of the newly allocated page
to SYNC_IBUF_TREE_NODE_NEW after latching the insert buffer tree root.
This bug always was bogus UNIV_SYNC_DEBUG alarm. The function
buf_block_dbg_add_level() is a no-op unless UNIV_SYNC_DEBUG is defined.
When there is a secondary index on a column prefix of an externally
stored column and an entry in the secondary index is shorter than the
reserved prefix length, it should mean that the secondary index entry
is holding the complete column value. When comparing this secondary
index column value to the column in the clustered index row, we must
compare the entire prefix that was fetched from the clustered
index. The bug was that we would just compare that the column in the
clustered index starts with the value found in the secondary index
column.
This bug affects only the InnoDB Barracuda formats (ROW_FORMAT=DYNAMIC
and ROW_FORMAT=COMPRESSED), in which columns that are stored off-page
in the clustered index do not contain any prefix in the clustered
index record.
row_sel_sec_rec_is_for_blob(): Add the parameter prefix_len, for
ifield->prefix_len. Add some assertions.
Sorry, I did not manage to produce a test case. This patch does
produce correct results on the data set that Michael isolated on our
test machine. That was with the purge and background rollback
suspended, because they would make the bug go away.
rb:760 approved by Sunny Bains
This patch corrects an error encountered in PB where Windows machines
are built in release mode have an extraneous parameter added in place
of the --console option. This is caused by the insert of '(null'
instead of an empty string. In non-debug mode, the string is explicitly
set to an empty string.
Patch also fixes a result mismatch on Windows machines.
