+
+1) Ensure that there are no uncommitted changes or unpushed commits,
+ and that you are up to date with the latest commits in the central
+ repository. Here are a couple of useful commands:
+
+ git diff (no output)
+
+ git status (should report "nothing to commit")
+
+ git log master...origin (no output; note: *3* dots)
+
+2) Increment pixman_(major|minor|micro) in configure.ac according to
+ the directions in that file.
+
+3) Make sure that new version works, including
+
+ - make distcheck passes
+
+ - the X server still works with the new pixman version
+ installed
+
+ - the cairo test suite hasn't gained any new failures compared
+ to last pixman version.
+
+4) Use "git commit" to record the changes made in step 2 and 3.
+
+5) Generate and publish the tar files by running
+
+ make PREV=<last version> GPGKEY=<your gpg key id> release-publish
+
+ If your freedesktop user name is different from your local one,
+ then also set the variable USER to your freedesktop user name.
+
+6) Run
+
+ make release-publish-message
+
+ to generate a draft release announcement. Edit it as appropriate and
+ send it to
+
+ cairo-announce@cairographics.org
+
+ pixman@lists.freedesktop.org
+
+ xorg-announce@lists.freedesktop.org
+
+7) Increment pixman_micro to the next larger (odd) number in
+ configure.ac. Commit this change, and push all commits created
+ during this process using
+
+ git push
+ git push --tags
+
+ You must use "--tags" here; otherwise the new tag will not
+ be pushed out.

+#
+# - Released development versions have an odd MINOR number

+ * A function, which can be used as a core part of the test programs,
+ * intended to detect various problems with the help of fuzzing input
+ * to pixman API (according to some templates, aka "smart" fuzzing).
+ * Some general information about such testing can be found here:
+ * http://en.wikipedia.org/wiki/Fuzz_testing
+ *
+ * It may help detecting:
+ * - crashes on bad handling of valid or reasonably invalid input to
+ * pixman API.
+ * - deviations from the behavior of older pixman releases.
+ * - deviations from the behavior of the same pixman release, but
+ * configured in a different way (for example with SIMD optimizations
+ * disabled), or running on a different OS or hardware.
+ *
+ * The test is performed by calling a callback function a huge number
+ * of times. The callback function is expected to run some snippet of
+ * pixman code with pseudorandom variations to the data feeded to
+ * pixman API. A result of running each callback function should be
+ * some deterministic value which depends on test number (test number
+ * can be used as a seed for PRNG). When 'verbose' argument is nonzero,
+ * callback function is expected to print to stdout some information
+ * about what it does.
+ *
+ * Return values from many small tests are accumulated together and
+ * used as final checksum, which can be compared to some expected
+ * value. Running the tests not individually, but in a batch helps
+ * to reduce process start overhead and also allows to parallelize
+ * testing and utilize multiple CPU cores.
+ *
+ * The resulting executable can be run without any arguments. In
+ * this case it runs a batch of tests starting from 1 and up to
+ * 'default_number_of_iterations'. The resulting checksum is
+ * compared with 'expected_checksum' and FAIL or PASS verdict
+ * depends on the result of this comparison.
+ *
+ * If the executable is run with 2 numbers provided as command line
+ * arguments, they specify the starting and ending numbers for a test
+ * batch.
+ *
+ * If the executable is run with only one number provided as a command
+ * line argument, then this number is used to call the callback function
+ * once, and also with verbose flag set.
