* 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
Modified f argument, for F. From man pages:
" -F Extra full format. See the -f option, which -F implies."
The following columns have been added to the output, due to this
change:
SZ size in physical pages of the core image of the process.
This includes text, data, and stack space. Device mappings
are currently excluded; this is subject to change.
RSS resident set size, the non-swapped physical memory that a
task has used (inkiloBytes).
PSR processor that process is currently assigned to.
