[libvirt] [PATCH 5/5] python: use libvirt_util to avoid raw free

This patch starts the process of elevating the python binding code to be on the same level as the rest of libvirt when it comes to requiring good coding styles. Statically linking against the libvirt_util library makes it much easier to write good code, rather than having to open-code and reinvent things locally. Done by global search and replace of s/free(/VIR_FREE(/, followed by hand-inspection of remaining malloc and redundant memset. * cfg.mk (exclude_file_name_regexp--sc_prohibit_raw_allocation): Remove python from exemption. * python/Makefile.am (INCLUDES): Add gnulib and src/util. Drop $(top_builddir)/$(subdir), as automake already guarantees that. (mylibs, myqemulibs): Pull in libvirt_util and gnulib. (libvirtmod_la_CFLAGS): Catch compiler warnings if configured to use -Werror. * python/typewrappers.c (libvirt_charPtrSizeWrap) (libvirt_charPtrWrap): Convert free to VIR_FREE. * python/generator.py (print_function_wrapper): Likewise. * python/libvirt-override.c: Likewise. --- cfg.mk | 2 +- python/Makefile.am | 18 ++- python/generator.py | 2 +- python/libvirt-override.c | 364 +++++++++++++++++++++------------------------ python/typewrappers.c | 8 +- 5 files changed, 194 insertions(+), 200 deletions(-) diff --git a/cfg.mk b/cfg.mk index f9c1558..dcf44bb 100644 --- a/cfg.mk +++ b/cfg.mk @@ -744,7 +744,7 @@ exclude_file_name_regexp--sc_prohibit_nonreentrant = \ ^((po|tests)/|docs/.*py$$|tools/(virsh|console)\.c$$) exclude_file_name_regexp--sc_prohibit_raw_allocation = \ - ^(src/util/memory\.[ch]|(examples|python)/.*)$$ + ^(src/util/memory\.[ch]|examples/.*)$$ exclude_file_name_regexp--sc_prohibit_readlink = ^src/util/util\.c$$ diff --git a/python/Makefile.am b/python/Makefile.am index 81b160a..9b791d7 100644 --- a/python/Makefile.am +++ b/python/Makefile.am @@ -7,9 +7,13 @@ SUBDIRS= . tests INCLUDES = \ $(PYTHON_INCLUDES) \ + -I$(top_builddir)/gnulib/lib \ + -I$(top_srcdir)/gnulib/lib \ + -I$(top_builddir)/src \ + -I$(top_srcdir)/src \ + -I$(top_srcdir)/src/util \ -I$(top_builddir)/include \ -I$(top_srcdir)/include \ - -I$(top_builddir)/$(subdir) \ $(GETTEXT_CPPFLAGS) AM_CFLAGS = $(WARN_CFLAGS) @@ -35,8 +39,14 @@ EXTRA_DIST = \ $(DOCS) if WITH_PYTHON -mylibs = $(top_builddir)/src/libvirt.la -myqemulibs = $(top_builddir)/src/libvirt-qemu.la +mylibs = \ + $(top_builddir)/src/libvirt.la \ + $(top_builddir)/src/libvirt_util.la \ + $(top_builddir)/gnulib/lib/libgnu.la +myqemulibs = \ + $(top_builddir)/src/libvirt-qemu.la \ + $(top_builddir)/src/libvirt_util.la \ + $(top_builddir)/gnulib/lib/libgnu.la all-local: libvirt.py libvirt_qemu.py @@ -46,7 +56,7 @@ libvirtmod_la_SOURCES = libvirt-override.c typewrappers.c nodist_libvirtmod_la_SOURCES = libvirt.c libvirt.h # Python <= 2.4 header files contain a redundant decl, hence we # need extra flags here -libvirtmod_la_CFLAGS = $(WARN_PYTHON_CFLAGS) +libvirtmod_la_CFLAGS = $(WARN_CFLAGS) $(WARN_PYTHON_CFLAGS) libvirtmod_la_LDFLAGS = -module -avoid-version -shared -L$(top_builddir)/src/.libs \ $(CYGWIN_EXTRA_LDFLAGS) diff --git a/python/generator.py b/python/generator.py index 0728519..98072f0 100755 --- a/python/generator.py +++ b/python/generator.py @@ -580,7 +580,7 @@ def print_function_wrapper(module, name, output, export, include): if ret[0] == 'void': if file == "python_accessor": if args[1][1] == "char *": - c_call = "\n free(%s->%s);\n" % ( + c_call = "\n VIR_FREE(%s->%s);\n" % ( args[0][0], args[1][0], args[0][0], args[1][0]) c_call = c_call + " %s->%s = (%s)strdup((const xmlChar *)%s);\n" % (args[0][0], args[1][0], args[1][1], args[1][0]) diff --git a/python/libvirt-override.c b/python/libvirt-override.c index 18849f8..68e0b55 100644 --- a/python/libvirt-override.c +++ b/python/libvirt-override.c @@ -4,7 +4,7 @@ * entry points where an automatically generated stub is * unpractical * - * Copyright (C) 2005, 2007-2011 Red Hat, Inc. + * Copyright (C) 2005, 2007-2012 Red Hat, Inc. * * Daniel Veillard <veillard(a)redhat.com&gt;
