[Qemu-devel] [PATCH] scripts: provide a script for checking glib symbol usage

[Daniel P. Berrange]

There are frequently patches submitted for merge which use
symbols only defined by newer glib versions that the max
version currently permitted by QEMU (ie glib==2.22). The
glib 2.32 release introduced GLIB_VERSION_MIN_REQUIRED and
GLIB_VERSION_MAX_ALLOWED macros to allow apps to declare
what they want. Unfortunately QEMU has a glib-compat.h
file which backports certain functions from newer glib
which confuses the glib version checking macros. This is
effectively preventing their use in QEMU. The version check
macros also don't cover all versions back to 2.22 so any
checks are incomplete.

This patch takes a different approach, by providing a script
that can validate that source files are only using glib
functions & macros present in the minimum declared glib version,
by doing static analysis of the source and comparing to a
previously defined list of permitted symbols.

The list of functions/macros was extracted from the glib 2.22
HTML docs symbol index using

 $ grep '<dt>' /usr/share/gtk-doc/html/glib/ix01.html | \
    awk {'print $1}' | \
    sed -e 's/<dt>//' -e 's/,//' | \
    grep -E -i '^g_' | \
    sort > scripts/glib-syms.txt

The script works by simply searching through the .c and .h
files looking for anything that looks like a function or
macro call, starting with a 'G_' or 'g_' prefix. This is
not a 100% exact science, but with a few override lists it
provides a practical/usable level of detection of mistakes.

This patch creates a 'scripts/Makefile' file which is intended
to accumulate various other style checks, similar to those done
by 'checkpatch.pl', but operating against the entire source
tree rather than just new patches.

The check can be invoked using 'make check-style' in the top
level directory.

Example output when the check fails would look like:

$ make check-style
tests/test-io-task.c:151: 'g_thread_ref' symbol not provided in min glib version
tests/test-io-task.c:172: 'g_thread_ref' symbol not provided in min glib version
tests/test-io-task.c:216: 'g_thread_unref' symbol not provided in min glib 
version
tests/test-io-task.c:217: 'g_thread_unref' symbol not provided in min glib 
version
tests/test-io-task.c:260: 'g_thread_unref' symbol not provided in min glib 
version
tests/test-io-task.c:261: 'g_thread_unref' symbol not provided in min glib 
version
