* merging changes done to the key cache since May 2006 into Maria * enabling two small enough page cache's unit tests by default * fix to have non-buffered output in unit tests (to not have a false timeout killing in pushbuild) (patch given by Serg) * removing some warnings of gcc -ansi include/lf.h: getting rid of "warning: ISO C does not allow extra `;' outside of a function" (gcc -ansi) mysys/lf_hash.c: getting rid of "warning: ISO C does not allow extra `;' outside of a function" (gcc -ansi) mysys/mf_pagecache.c: Cosmetic changes to minimize the diff with the key cache. #define PAGECACHE_DEBUG_LOG is not needed (just define PAGECACHE_DEBUG if you want) (this change removes "warning: 'pagecache_debug_print' declared `static' but never defined"). Importing changes made to mf_keycache.c since May 2006, into the page cache. Disabling online resizing in the page cache. Fix for "warning: ISO C90 forbids mixed declarations and code". unittest/mysys/Makefile.am: Of the page cache's unit tests, two are small enough to run on pushbuild, renaming them to a -t suffix. unittest/mytap/tap.c: pushbuild kills a test after seeing no output from it for 10 minutes; so we set the mytap framework to not buffer output (patch given by Serg) so that output is seen more frequently and not "all at the end of the test".
Unit tests directory structure
------------------------------
This is the current structure of the unit tests. More directories
will be added over time.
mytap Source for the MyTAP library
mysys Tests for mysys components
bitmap-t.c Unit test for MY_BITMAP
base64-t.c Unit test for base64 encoding functions
examples Example unit tests.
core-t.c Example of raising a signal in the middle of the test
THIS TEST WILL STOP ALL FURTHER TESTING!
simple-t.c Example of a standard TAP unit test
skip-t.c Example where some test points are skipped
skip_all-t.c Example of a test where the entire test is skipped
todo-t.c Example where test contain test points that are TODO
no_plan-t.c Example of a test with no plan (avoid this)
Executing unit tests
--------------------
To make and execute all unit tests in the directory:
make test
Observe that the tests in the examples/ directory are just various
examples of tests and are not expected to pass.
Adding unit tests
-----------------
Add a file with a name of the format "foo-t.c" to the appropriate
directory and add the following to the Makefile.am in that directory
(where ... denotes stuff already there):
noinst_PROGRAMS = ... foo-t
Note, it's important to have "-t" at the end of the filename, otherwise the
test won't be executed by 'make test' !
