* PT-1059 - Tools can't parse index names containing newlines
Fixed regular expressions in TableParser.
Added test case, including test for new lines in the column name
* PT-1059 - Tools can't parse index names containing newlines
Disabled pt-1637.t until PT-2174 is fixed.
Updated number of tables in b/t/pt-table-checksum/issue_1485195.t
* Patch newlines in table columns (#369)
Will accept this change as part of the fix for PT-1059 - Tools cannot parse index names containing new lines. We will later fix the issue with the patch ourselves.
mysql 5.6.40 allows newlines in column names however the following code:
my @defs = $ddl =~ m/^(\s+`.*?),?$/gm;
breaks due to it detecting newlines as line ends. The 'm' argument at the end does this by auto-detecting lines by newline characters.
To correct this issue I've made use of zero-length assertions known as " positive lookback"
https://www.regular-expressions.info/lookaround.html
what does it do?
m/(?:(?<=,\n)|(?<=\(\n))(\s+`(?:.|\n)+?`.+?),?\n/g;
TLDR:
Treat the string as one long string and don't treat \n as the end of a line.
look for (\s+`(?:.|\n)+?`.+?),?\n
if one of those matches look at what precedes the string
if it's ',\n' or ')\n' the string matches. Only save what's in (\s+`(?:.|\n)+?`.+?),?\n
m/ is declaring this a matching regex.
(?:(?<=,\n)|(?<=(\n)) This is an OR statement including two look-behind clauses. The ?: tells the enclosing parentheses to not store the result as a variable. I've put the two look-behinds in this OR statement below this line:
(?<=,\n) Look behind the matched string for a comma followed by a newline, the comma must be there for this look behind to match.
(?<=(\n) Look behind the matched string for a open parentheses followed by a newline, the open parentheses must be there.
(\s+`(?:.|\n)+?`.+?),?\n This is the actual match. Match newline character followed by one or more spaces followed by back-tick followed by a character which can be any character or a newline one or more times, but don't be greedy and take the rest of the match into consideration. Followed by a back tick and any character one or more times. This match stops where there is a comma or failing that a newline following a back tick and some characters.
,?\n match a comma that may not be there followed by a newline.
/g don't stop if this pattern matches keep looking for more patterns to the end of the string.
* PT-1059 - Tools can't parse index names containing newlines
Placed fix from PR-369 into proper place and created test case for this fix.

* PT-2084 Readding SHOW SLAVE STATUS outputs to pt-stalk
Before, they were only gathered if version was 5.6 or prior.
Now, they are always gathered, no matter what version.
Since ${mysql_version} is only major.minor, we can't yet add
SHOW REPLICA STATUS, because it starts on 8.0.22 and we have
no way to check that. We will need to wait for 8.1 release.
* PT-2084 Ran update-modules to generate binaries with changes.
* PT-2084 Added checks for preemptive 8.1 SHOW SLAVE STATUS removal.
* PT-2084 Adding test case for SHOW SLAVE STATUS
* Update t/pt-stalk/pt-stalk-replication.t

- Enabled t/pt-table-checksum/error_handling.t for MySQL 8.0
- Fixed test t/pt-table-checksum/fnv_64.t and it's samples file
t/pt-table-checksum/samples/fnv64-sakila-city.txt
to reflect new function name convention and
changes after 62d84e5dba
* PT-2138 - Fix tests for pt-table-checksum
- Fixed t/pt-table-checksum/issue_1485195.t, so it checks only one table and
isn't get broken when we add tables into percona_test database

- Added SLOW_TESTS check to pt-1616.t
- Updated pt-226.t to include the fix for PT-1766
- For replication_filters.t: excluded false positive expression for tests 10 and 11 and added sys schema to the list of checked databases for 8.0
- Changed get_slaves in lib/MasterSlave.pm, so it returns slave's parent, required for wait_for_slaves in pt-table-checksum to work properly with chained slaves
* PT-2138 - Fix tests for pt-table-checksum
- Modified pt-204.t to support 8.0 and diffs in system tables due to timestamps
Moved the fix for PT-1616 into the proper place: lib/NibbleIterator.pm
* PT-2138 - Fix tests for pt-table-checksum
- pxc.t -added mysql.proxies_priv into ignore list, because its timestamp is different on node
- pxc.t - removed FORK=pxc from statup options for slave (non-cluster) nodes
- pxc.t - disabled wsrep replication with help of the variable wsrep_on: sql_log_bin doesn't disable wsrep replication anymore. See https://jira.percona.com/browse/PXC-3464 for details
- Removed data.tar.gz from 5.7 sandbox configuration, because it has an outdated definition for Performance Schema
- Disabled pxc.t for version 8.0 until PT-1699 is fixed

* PT-1052: fix for pt-summary
* Re-added fix from commit 71fae6d117 into proper place: library directory
Added tests for PT-1052 (pt-summary only)
* Fixed tests for pt-summary,
set locale for pt-summary tests, so they are not affected by user environment.
Finished tests for PT-1052
* Added fix for PT-1983 into the proper place: library file
* PT-1052: fix for pt-stalk which now includes numastat data
* PT-1897 pt-stalk on MySQL 8 not collecting lock information
For version prior 8.0 pt-stalk continue using Information Schema INNODB_LOCKS and INNODB_LOCK_WAITS tables for collecting lock information.
For version 8.0 and higher pt-stalk uses tables data_locks and data_lock_waits in Performance Schema
* PT-1897 - Better MariaDB support
We cannot simply compare version number with 8.0 to identify if lock tables are in Performance Schema,
because MariaDB 10.x still have them in the Information Schema.
Therefore added additional flag, indicating which syntax we should use
* Tests for PT-1897
After discussion change only affects error message that is more user-friendly now.
I also added two tests that check how open_tables function works in both cases:
with number of open tables less tha 1000 and greater than 1000
This commit:
1. Moves all changes to the proper place: lib/bash/collect.sh
2. Refactors pt-stalk so it is more modular
3. Places fix for PT-1734 into the right place: lib/bash/collect.sh
4. Fixes tests for PT-1336

Since now NibbleIterator can fallback to nibble (from one chunk) pt-osc
can nibble tables even if due to unacurate stats, it choses one nible as
the initial nibbling method.
