I think it's important to be able to test it. In principle we could also test it through the higher-level interface of x11_convert_to_vconsole, but x11_convert_to_vconsole also uses find_converted_keymap, and it's better to test at this lower level. Note that find_legacy_keymap might be a bit of a misnomer, because we'd probably want to keep kbd-model-map even if the "legacy" layouts went away. So we might want to change this name, but I'm leaving that for another commit. --- .gitignore | 1 + Makefile.am | 12 ++ src/locale/keymap-util.c | 5 +- src/locale/keymap-util.h | 1 + src/locale/test-keymap-util.c | 216 ++++++++++++++++++++++++++++++++++ 5 files changed, 233 insertions(+), 2 deletions(-) create mode 100644 src/locale/test-keymap-util.c diff --git a/.gitignore b/.gitignore index 091b400182..f7db68b4a6 100644 --- a/.gitignore +++ b/.gitignore @@ -217,6 +217,7 @@ /test-journal-stream /test-journal-syslog /test-journal-verify +/test-keymap-util /test-libsystemd-sym* /test-libudev /test-libudev-sym* diff --git a/Makefile.am b/Makefile.am index 4ff39987ac..fc6f3bf6d5 100644 --- a/Makefile.am +++ b/Makefile.am @@ -4782,6 +4782,18 @@ dist_pkgdata_DATA = \ src/locale/kbd-model-map \ src/locale/language-fallback-map +test_keymap_util_SOURCES = \ + src/locale/test-keymap-util.c \ + src/locale/keymap-util.c \ + src/locale/keymap-util.h + +test_keymap_util_LDADD = \ + libshared.la \ + -ldl + +tests += \ + test-keymap-util + localectl_SOURCES = \ src/locale/localectl.c diff --git a/src/locale/keymap-util.c b/src/locale/keymap-util.c index 1827014b89..68b80a4801 100644 --- a/src/locale/keymap-util.c +++ b/src/locale/keymap-util.c @@ -522,7 +522,7 @@ int find_converted_keymap(const char *x11_layout, const char *x11_variant, char return 0; } -static int find_legacy_keymap(Context *c, char **new_keymap) { +int find_legacy_keymap(Context *c, char **new_keymap) { _cleanup_fclose_ FILE *f; unsigned n = 0; unsigned best_matching = 0; @@ -617,6 +617,7 @@ int find_language_fallback(const char *lang, char **language) { _cleanup_fclose_ FILE *f = NULL; unsigned n = 0; + assert(lang); assert(language); f = fopen(SYSTEMD_LANGUAGE_FALLBACK_MAP, "re"); @@ -651,7 +652,7 @@ int x11_convert_to_vconsole(Context *c) { !isempty(c->vc_keymap) || !isempty(c->vc_keymap_toggle); - context_free_x11(c); + context_free_vconsole(c); } else { char *new_keymap = NULL; int r; diff --git a/src/locale/keymap-util.h b/src/locale/keymap-util.h index 244dd62563..20ef2a4a34 100644 --- a/src/locale/keymap-util.h +++ b/src/locale/keymap-util.h @@ -33,6 +33,7 @@ typedef struct Context { } Context; int find_converted_keymap(const char *x11_layout, const char *x11_variant, char **new_keymap); +int find_legacy_keymap(Context *c, char **new_keymap); int find_language_fallback(const char *lang, char **language); int context_read_data(Context *c); diff --git a/src/locale/test-keymap-util.c b/src/locale/test-keymap-util.c new file mode 100644 index 0000000000..680aae6228 --- /dev/null +++ b/src/locale/test-keymap-util.c @@ -0,0 +1,216 @@ +/*** + This file is part of systemd. + + Copyright 2016 Zbigniew Jędrzejewski-Szmek + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Output a message at notice level, becuase not converting the X11 keymap is most likely an error. We usually do not output non-debug messages from "library" code, but this isn't really library code, it's split out to a separate file only to allow it to be called from tests. (pl is not converted because we only have a mapping for pl2. This is intentional, even though we might want to change this.

This seems wrong, and we should match single layouts like too. So 'ru', 'ru,us' now both match. startswith_comma is changed to not require a comma, i.e. check that the prefix matches until a comma or the end of the string. Note that startswith_comma is called twice. At the first site, we check that strings are not equal beforehand, so this change to startswith_comma has no effect. At the second site, it does have an effect, as described above. --- src/locale/keymap-util.c | 2 +- src/locale/test-keymap-util.c | 8 ++++++++ 2 files changed, 9 insertions(+), 1 deletion(-) diff --git a/src/locale/keymap-util.c b/src/locale/keymap-util.c index fe29594ccc..17bef9e481 100644 --- a/src/locale/keymap-util.c +++ b/src/locale/keymap-util.c @@ -39,7 +39,7 @@ static bool startswith_comma(const char *s, const char *prefix) { if (!s) return false; - return *s == ','; + return *s == ',' || *s == '\0'; } static const char* strnulldash(const char *s) { diff --git a/src/locale/test-keymap-util.c b/src/locale/test-keymap-util.c index 8dde764a50..1e30fa4cb0 100644 --- a/src/locale/test-keymap-util.c +++ b/src/locale/test-keymap-util.c @@ -199,6 +199,14 @@ static void test_x11_convert_to_vconsole(void) { assert_se(x11_convert_to_vconsole(&c) == 1); assert_se(streq(c.vc_keymap, "ru")); + + /* https://bugzilla.redhat.com/show_bug.cgi?id=1333998 */ + log_info("/* test with a simple new mapping (ru:) */"); + assert_se(free_and_strdup(&c.x11_layout, "ru") >= 0); + assert_se(free_and_strdup(&c.x11_variant, NULL) >= 0); + + assert_se(x11_convert_to_vconsole(&c) == 0); + assert_se(streq(c.vc_keymap, "ru")); } int main(int argc, char **argv) { From cabffaf86c17cdf74f92b8ef168fb9668f699c14 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Sat, 4 Jun 2016 18:15:42 -0400 Subject: [PATCH 7/7] test-keymap-util: use kbd-model-map/language-fallback-map from $(srcdir) This adds (undocumented) environment variables SYSTEMD_KBD_MODEL_MAP and SYSTEMD_LANGUAGE_FALLBACK_MAP, which, if set, override compiled-in locations of those two files.
