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.
mysql-test/lib/mtr_process.pl:
Added a function to send a signal to a process.
mysql-test/mysql-test-run.pl:
Changed procedure of stopping Instance Manager.
1. Try to stop IM normally (by sending SIGTERM);
2. If one of IM-related processes is still alive,
kill them all by SIGKILL and complain in the log.
server-tools/instance-manager/manager.cc:
Made create_pid_file() available for the whole project.
server-tools/instance-manager/manager.h:
Made create_pid_file() available for the whole project.
server-tools/instance-manager/mysqlmanager.cc:
Dump PID of angel process into file.
server-tools/instance-manager/options.cc:
Added an option to allow to customize angel pid file name.
server-tools/instance-manager/options.h:
Added an option to allow to customize angel pid file name.
This directory contains a test suite for the MySQL daemon. To run the currently existing test cases, simply execute ./mysql-test-run in this directory. It will fire up the newly built mysqld and test it. Note that you do not have to have to do "make install", and you could actually have a co-existing MySQL installation. The tests will not conflict with it. All tests must pass. If one or more of them fail on your system, please read the following manual section for instructions on how to report the problem: http://dev.mysql.com/doc/mysql/en/mysql-test-suite.html If you want to use an already running MySQL server for specific tests, use the --extern option to mysql-test-run. Please note that in this mode, the test suite expects you to provide the names of the tests to run. For example, here is the command to run the "alias" and "analyze" tests with an external server: mysql-test-run --extern alias analyze To match your setup, you might also need to provide --socket, --user, and other relevant options. With no test cases named on the command line, mysql-test-run falls back to the normal "non-extern" behavior. The reason for this is that some tests cannot run with an external server. You can create your own test cases. To create a test case, create a new file in the t subdirectory using a text editor. The file should have a .test extension. For example: xemacs t/test_case_name.test In the file, put a set of SQL statements that create some tables, load test data, and run some queries to manipulate it. We would appreciate it if you name your test tables t1, t2, t3 ... (to not conflict too much with existing tables). Your test should begin by dropping the tables you are going to create and end by dropping them again. This ensures that you can run the test over and over again. If you are using mysqltest commands (like result file names) in your test case, you should create the result file as follows: mysql-test-run --record test_case_name or mysqltest --record < t/test_case_name.test If you only have a simple test cases consisting of SQL statements and comments, you can create the test case in one of the following ways: mysql-test-run --record test_case_name mysql test < t/test_case_name.test > r/test_case_name.result mysqltest --record --record-file=r/test_case_name.result < t/test_case_name.test When this is done, take a look at r/test_case_name.result - If the result is incorrect, you have found a bug. In this case, you should edit the test result to the correct results so that we can verify that the bug is corrected in future releases. To submit your test case, put your .test file and .result file(s) into a tar.gz archive, add a README that explains the problem, ftp the archive to ftp://support.mysql.com/pub/mysql/secret/ and send a mail to bugs@lists.mysql.com
