The test innodb.innodb_wl6326 that had been disabled in 10.4 due to
MDEV-21535 is failing on 10.5 due to a different reason: the removal
of the MLOG_COMP_END_COPY_CREATED operations in MDEV-12353
commit 276f996af9 caused PAGE_LAST_INSERT
to be set to something nonzero by the function page_copy_rec_list_end().
This in turn would cause btr_page_get_split_rec_to_right() to behave
differently: we would not attempt to split the page at all, but simply
insert the new record into the new, empty, right leaf page.
Even though the change reduced the sizes of some tables, it is better
to aim for balanced trees.
page_copy_rec_list_end(), PageBulk::finishPage():
Preserve PAGE_LAST_INSERT, PAGE_N_DIRECTION, PAGE_DIRECTION.
PageBulk::finish(): Move some common code from PageBulk::finishPage().
Instead of writing the high-level redo log records
MLOG_LIST_END_COPY_CREATED, MLOG_COMP_LIST_END_COPY_CREATED
write log for each individual insert of a record.
page_copy_rec_list_end_to_created_page(): Remove.
This will improve the fill factor of some pages.
Adjust some tests accordingly.
PageBulk::init(), PageBulk::finish(): Avoid setting bogus limits
to PAGE_HEAP_TOP and PAGE_N_DIR_SLOTS. Avoid accessor functions
that would enforce these limits before the correct ones are set
at the end of PageBulk::finish().
Added --skip-test-db option to mysql_install_db. If specified, no test
database created and relevant grants issued.
Removed --skip-auth-anonymous-user option of mysql_install_db. Now it is
covered by --skip-test-db.
Dropped some Debian patches that did the same.
Removed unused make_win_bin_dist.1, make_win_bin_dist and
mysql_install_db.pl.in.
1. Special mode to search in error logs: if SEARCH_RANGE is not set,
the file is considered an error log and the search is performed
since the last CURRENT_TEST: line
2. Number of matches is printed too. "FOUND 5 /foo/ in bar".
Use greedy .* at the end of the pattern if number of matches
isn't stable. If nothing is found it's still "NOT FOUND",
not "FOUND 0".
3. SEARCH_ABORT specifies the prefix of the output.
Can be "NOT FOUND" or "FOUND" as before,
but also "FOUND 5 " if needed.
innodb_file_format=Barracuda is the default in MariaDB 10.2.
Do not set it, because the option will be removed in MariaDB 10.3.
Also, do not set innodb_file_per_table=1 because it is the default.
Note that MDEV-11828 should fix the test innodb.innodb-64k
already in 10.1.
Problem was that for encryption we use temporary scratch area for
reading and writing tablespace pages. But if page was not really
decrypted the correct updated page was not moved to scratch area
that was then written. This can happen e.g. for page 0 as it is
newer encrypted even if encryption is enabled and as we write
the contents of old page 0 to tablespace it contained naturally
incorrect space_id that is then later noted and error message
was written. Updated page with correct space_id was lost.
If tablespace is encrypted we use additional
temporary scratch area where pages are read
for decrypting readptr == crypt_io_buffer != io_buffer.
Destination for decryption is a buffer pool block
block->frame == dst == io_buffer that is updated.
Pages that did not require decryption even when
tablespace is marked as encrypted are not copied
instead block->frame is set to src == readptr.
If tablespace was encrypted we copy updated page to
writeptr != io_buffer. This fixes above bug.
For encryption we again use temporary scratch area
writeptr != io_buffer == dst
that is then written to the tablespace
(1) For normal tables src == dst == writeptr
ut_ad(!encrypted && !page_compressed ?
src == dst && dst == writeptr + (i * size):1);
(2) For page compressed tables src == dst == writeptr
ut_ad(page_compressed && !encrypted ?
src == dst && dst == writeptr + (i * size):1);
(3) For encrypted tables src != dst != writeptr
ut_ad(encrypted ?
src != dst && dst != writeptr + (i * size):1);
