- BUG#15934: Instance manager fails to work;
- BUG#18020: IM connect problem;
- BUG#18027: IM: Server_ID differs;
- BUG#18033: IM: Server_ID not reported;
- BUG#21331: Instance Manager: Connect problems in tests;
The only test suite has been changed
(server codebase has not been modified).
- Make mysql-test-run.pl restart a crashed/stopped process if it was expected it should crash.
- Added testcase for "crash_commit_before", which tests behaviour when server crashes just before commit.
* The testcase first write a small var/tmp/master0.expect file indicating expected crash
* Then sets "DEBUG" variable to for example "d,crash_commit_before" and then executes a commit.
* The server will crash and be brought back up by mysql-test-run.pl
* Test case will then wait for the process to come back online before continuing.
by default we never run disabled tests (even if they're
explicitely listed on the command-line). We add an option --enable-disabled
which will run tests even though they are disabled, and will print, for each
such test, the comment explaining why it was disabled.
The reason for the change is when you want to run "all tests which are about
NDB" for example: mysql-test-run.pl t/*ndb*.test used to run some disabled
NDB tests, causing failures, causing investigations.
Code amended and approved by Kent.
tests fail on FreeBSD.
The patch contains of the following:
- make Instance Manager, running in the daemon mode, dump
the pid of angel-process in the special file;
- default value of angel-pid-file-name is 'mysqlmanager.angel.pid';
- if ordinary (IM) pid-file-name is specified in the configuration,
angel-pid-file-name is updated according to the following
rule: extension of the basename of pid-file-name is replaced by
'.angel.pid.
For example:
- pid-file-name: /tmp/im.pid
=> angel-pid-file-name: /tmp/im.angel.pid
- pid-file-name: /tmp/im.txt
=> angel-pid-file-name: /tmp/im.angel.pid
- pid-file-name: /tmp/5.0/im
=> angel-pid-file-name: /tmp/5.0/im.angel.pid
- add support for configuration option to customize angel
pid file name;
- fix test suite to use angel pid to kill Instance Manager
by all means if something went wrong.
Background
----------
The problem is that on some OSes (FreeBSD for one) Instance
Manager does not get SIGTERM, so can not shutdown gracefully.
Test suite wasn't able to cope with it, so this leads to the
mess in test results.
The problem should be split into two:
- fix signal handling;
- fix test suite.
This patch fixes test suite so that it will be able to kill
uncooperative Instance Manager. In order to achieve this,
test suite needs to know PID of IM Angel process.
