[libvirt] [PATCH v4] util: Add virGettextInitialize, convert the code
Take setlocale/gettext error handling pattern from tools/virsh-* and use it for all standalone binaries via a new shared virGettextInitialize routine. The virsh* pattern differed slightly from other callers. All users now consistently: * Ignore setlocale errors. virsh has done this forever, presumably for good reason. This has been partially responsible for some bug reports: https://bugzilla.redhat.com/show_bug.cgi?id=1312688 https://bugzilla.redhat.com/show_bug.cgi?id=1026514 https://bugzilla.redhat.com/show_bug.cgi?id=1016158 * Report the failed function name * Report strerror --- v4: sigh, forgot to squash in a cfg.mk change cfg.mk | 13 +++++++++- daemon/libvirtd.c | 6 ++--- src/Makefile.am | 2 ++ src/libvirt_private.syms | 4 ++++ src/locking/lock_daemon.c | 6 ++--- src/locking/sanlock_helper.c | 9 ++----- src/logging/log_daemon.c | 6 ++--- src/lxc/lxc_controller.c | 6 ++--- src/network/leaseshelper.c | 12 +++------- src/security/virt-aa-helper.c | 12 +++------- src/storage/parthelper.c | 9 ++----- src/util/iohelper.c | 13 +++------- src/util/virgettext.c | 56 +++++++++++++++++++++++++++++++++++++++++++ src/util/virgettext.h | 25 +++++++++++++++++++ tools/virsh.c | 15 ++---------- tools/virt-admin.c | 15 ++---------- tools/virt-host-validate.c | 15 ++---------- tools/virt-login-shell.c | 14 ++--------- tools/vsh.c | 2 -- 19 files changed, 128 insertions(+), 112 deletions(-) create mode 100644 src/util/virgettext.c create mode 100644 src/util/virgettext.h diff --git a/cfg.mk b/cfg.mk index 8e8586f..90bb709 100644 --- a/cfg.mk +++ b/cfg.mk @@ -1037,6 +1037,15 @@ sc_prohibit_verbose_strcat: halt='Use strcat(a, b) instead of strncat(a, b, strlen(b))' \ $(_sc_search_regexp) +# Ensure that each .c file containing a "main" function also +# calls virGettextInitialize +sc_gettext_init: + @require='virGettextInitialize *\(' \ + in_vc_files='\.c$$' \ + containing='\<main *(' \ + halt='the above files do not call virGettextInitialize' \ + $(_sc_search_regexp) + # We don't use this feature of maint.mk. prev_version_file = /dev/null @@ -1133,7 +1142,9 @@ _test1=shunloadtest|virnettlscontexttest|virnettlssessiontest|vircgroupmock exclude_file_name_regexp--sc_avoid_write = \ ^(src/($(_src1))|daemon/libvirtd|tools/virsh-console|tests/($(_test1)))\.c$$ -exclude_file_name_regexp--sc_bindtextdomain = ^(tests|examples)/ +exclude_file_name_regexp--sc_bindtextdomain = .* + +exclude_file_name_regexp--sc_gettext_init = ^(tests|examples)/ exclude_file_name_regexp--sc_copyright_usage = \ ^COPYING(|\.LESSER)$$ diff --git a/daemon/libvirtd.c b/daemon/libvirtd.c index 3d38a46..5f66e8b 100644 --- a/daemon/libvirtd.c +++ b/daemon/libvirtd.c @@ -30,7 +30,6 @@ #include <getopt.h> #include <stdlib.h> #include <grp.h> -#include <locale.h> #include "libvirt_internal.h" #include "virerror.h" @@ -58,6 +57,7 @@ #include "locking/lock_manager.h" #include "viraccessmanager.h" #include "virutil.h" +#include "virgettext.h" #ifdef WITH_DRIVER_MODULES # include "driver.h" @@ -1172,9 +1172,7 @@ int main(int argc, char **argv) { {0, 0, 0, 0} };
