2011-03-09i18n: git-init "Initialized [...] repository" messageLibravatar Ævar Arnfjörð Bjarmason2-4/+10
These messages could benefit from splitting up. An earlier version of this patch began like this: const char *reinit_shared = _("Reinitialized existing shared Git repository in %s\n"); const char *init_shared = _("Initialized empty shared Git repository in %s\n"); const char *reinit_noshared = _("Reinitialized existing Git repository in %s\n"); const char *init_noshared = _("Initialized empty Git repository in %s\n"); But in the first round of gettextization I'm aiming to keep code changes to a minimum for ease of review. So just add a comment explaining to translators how the sprintf format gets used so they can cope for now if the language's grammar allows.

Change the user visible strings in init-db.c to use gettext localizations. This only converts messages which needed to be changed from "foo" to _("foo"), and didn't need any TRANSLATORS comments. I haven't marked the messages in init_db_usage or init_db_options for translation, since that would require additional changes in parse-options.c. Those can be done later.

2011-03-09i18n: add stub Q_() wrapper for ngettextLibravatar Jonathan Nieder1-2/+10
The Q_ function translates a string representing some pharse with an alternative plural form and uses the 'count' argument to choose which form to return. Use of Q_ solves the "%d noun(s)" problem in a way that is portable to languages outside the Germanic and Romance families. In English, the semantics of Q_(sing, plur, count) are roughly equivalent to count == 1 ? _(sing) : _(plur) while in other languages there can be more variants (count == 0; more random-looking rules based on the historical pronunciation of the number). Behind the scenes, the singular form is used to look up a family of translations and the plural form is ignored unless no translation is available. Define such a Q_ in gettext.h with the English semantics so C code can start using it to mark phrases with a count for translation. The name "Q_" is taken from subversion and stands for "quantity". Many projects just use ngettext directly without a wrapper analogous to _; we should not do so because git's gettext.h is meant not to conflict with system headers that might include libintl.h.

2011-03-08i18n: do not poison translations unless GIT_GETTEXT_POISON envvar is setLibravatar Jonathan Nieder4-3/+26
Tweak the GETTEXT_POISON facility so it is activated at run time instead of compile time. If the GIT_GETTEXT_POISON environment variable is set, _(msg) will result in gibberish as before; but if the GIT_GETTEXT_POISON variable is not set, it will return the message for human-readable output. So the behavior of mistranslated and untranslated git can be compared without rebuilding git in between. For simplicity we always set the GIT_GETTEXT_POISON variable in tests. This does not affect builds without the GETTEXT_POISON compile-time option set, so non-i18n git will not be slowed down.

2011-03-08i18n: add GETTEXT_POISON to simulate unfriendly translatorLibravatar Ævar Arnfjörð Bjarmason3-1/+17
Add a new GETTEXT_POISON compile-time parameter to make _(msg) always return gibberish. So now you can run make GETTEXT_POISON=YesPlease to get a copy of git that functions correctly (one hopes) but produces output that is in nobody's native language at all. This is a debugging aid for people who are working on the i18n part of the system, to make sure that they are not marking plumbing messages that should never be translated with _(). As new strings get marked for translation, naturally a number of tests will be broken in this mode. Tests that depend on output from Porcelain will need to be marked with the new C_LOCALE_OUTPUT test prerequisite. Newly failing tests that do not depend on output from Porcelain would be bugs due to messages that should not have been marked for translation. Note that the string we're using ("# GETTEXT POISON #") intentionally starts the pound sign. Some of Git's tests such as t3404-rebase-interactive.sh rely on interactive editing with a fake editor, and will needlessly break if the message doesn't start with something the interactive editor considers a comment. A future patch will fix fix the underlying cause of that issue by adding "#" characters to the commit advice automatically.

2011-03-08i18n: add no-op _() and N_() wrappersLibravatar Ævar Arnfjörð Bjarmason3-0/+28
The _ function is for translating strings into the user's chosen language. The N_ macro just marks translatable strings for the xgettext(1) tool without translating them; it is intended for use in contexts where a function call cannot be used. So, for example: fprintf(stderr, _("Expansion of alias '%s' failed; " "'%s' is not a git command\n"), cmd, argv[0]); and const char *unpack_plumbing_errors[NB_UNPACK_TREES_ERROR_TYPES] = { /* ERROR_WOULD_OVERWRITE */ N_("Entry '%s' would be overwritten by merge. Cannot merge."), [...] Define such _ and N_ in a new gettext.h and include it in cache.h, so they can be used everywhere. Each just returns its argument for now. _ is a function rather than a macro like N_ to avoid the temptation to use _("foo") as a string literal (which would be a compile-time error once _(s) expands to an expression for the translation of s).

2011-03-08commit, status: use status_printf{,_ln,_more} helpersLibravatar Jonathan Nieder2-66/+67
wt-status code is used to provide a reminder of changes included and not included for the commit message template opened in the operator's text editor by "git commit". Therefore each line of its output begins with the comment character "#": # Please enter the commit message for your changes. Lines starting Use the new status_printf{,_ln,_more} functions to take care of adding "#" to the beginning of such status lines automatically. Using these will have two advantages over the current code: - The obvious one is to force separation of the "#" from the translatable part of the message when git learns to translate its output. - Another advantage is that this makes it easier for us to drop "#" prefix in "git status" output in later versions of git if we want to.

2011-03-08commit: refer to commit template as s->fpLibravatar Jonathan Nieder1-14/+13
Instead of maintaining a local variable for it, use s->fp to keep track of where the commit message template should be written.

2011-03-08wt-status: add helpers for printing wt-status linesLibravatar Jonathan Nieder4-0/+93
Introduce status_printf{,_ln,_more} wrapper functions around color_vfprintf() which take care of adding "#" to the beginning of status lines automatically. The semantics: - status_printf() is just like color_fprintf() but it adds a "# " at the beginning of each line of output; - status_printf_ln() is a convenience function that additionally adds "\n" at the end; - status_printf_more() is a variant of status_printf() used to continue lines that have already started. It suppresses the "#" at the beginning of the first line.

2011-03-08compat: fall back on __va_copy if availableLibravatar Jonathan Nieder1-1/+10
Since an obvious implementation of va_list is to make it a pointer into the stack frame, implementing va_copy as "dst = src" will work on many systems. Platforms that use something different (e.g., a size-1 array of structs, to be assigned with *(dst) = *(src)) will need some other compatibility macro, though. Luckily, as the glibc manual hints, such systems tend to provide the __va_copy macro (introduced in GCC in March, 1997). By using that if it is available, we can cover our bases pretty well. Discovered by building with CC="gcc -std=c89" on an amd64 machine: $ make CC=c89 strbuf.o [...] strbuf.c: In function 'strbuf_vaddf': strbuf.c:211:2: error: incompatible types when assigning to type 'va_list' from type 'struct __va_list_tag *' make: *** [strbuf.o] Error 1 Explained-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-02-26strbuf: add strbuf_vaddfLibravatar Jeff King5-63/+25
In a variable-args function, the code for writing into a strbuf is non-trivial. We ended up cutting and pasting it in several places because there was no vprintf-style function for strbufs (which in turn was held up by a lack of va_copy). Now that we have a fallback va_copy, we can add strbuf_vaddf, the strbuf equivalent of vsprintf. And we can clean up the cut and paste mess.

2011-02-26compat: provide a fallback va_copy definitionLibravatar Jeff King2-1/+4
va_copy is C99. We have avoided using va_copy many times in the past, which has led to a bunch of cut-and-paste. From everything I found searching the web, implementations have historically either provided va_copy or just let your code assume that simple assignment of worked. So my guess is that this will be sufficient, though we won't really know for sure until somebody reports a problem.

Because '--immediate' stops test suite after first error, therefore in this mode test_debug 'cat gitweb.log' was never ran, thus in effect negating effect of '--debug' option. This made finidng the cause of errors in gitweb test sute difficult. Modify the gitweb_run test subroutine to run test_debug itself in the case of errors (and also remove "test_debug 'cat gitweb.log'" from gitweb tests). This makes it possible to run *gitweb tests* with --immediate ---debug combination of options; also it makes gitweb tests to not output spurious debug data that is not considered error.

Change S_ISREG($to_mode_oct) to S_ISREG($from_mode_oct) in the branch that handles from modes, not to modes. This logic appears to have been caused by copy/paste programming by Jakub Narebski in e8e41a93. It would be better to rewrite this code not to be duplicated, but I haven't done so.

Using the qw(...) construct as implicit parentheses was deprecated in perl 5.13.5. Change the relevant code in gitweb to not use the deprecated construct.

2011-02-14configure: use AC_LANG_PROGRAM consistentlyLibravatar Ralf Wildenhues2-39/+21
Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM and friends. Quoting autoconf-2.68/NEWS: ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and AC_RUN_IFELSE now warn if the first argument failed to use AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have a compelling reason why you cannot use AC_LANG_SOURCE but must avoid the warning. The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM} take care to supply the previously computed set of #defines (and include standard headers if so desired) for preprocessed languages like C and C++. In some cases, AC_LANG_PROGRAM is already used but not sufficiently m4-quoted, so we just need to add another set of [quotes] to prevent the autoconf warning from being triggered bogusly. Quoting all arguments (except when calling special macros that need to be expanded before recursion) is better style, anyway. These and more rules are described in detail in 'info Autoconf "Programming in M4"'. No change in the resulting config.mak.autogen after running ./configure intended.

2011-02-14string_list_append: always set util pointer to NULLLibravatar Jeff King1-0/+1
It is not immediately obvious that the util field may contain random bytes after appending an item. Especially since the string_list_insert* functions _do_ explicitly zero the util pointer. This does not appear to be a bug in any current git code, as all callers either fill in the util field immediately or never use it. However, it is worth it to be less surprising to new users of the string-list API who may expect it to be intialized to NULL.
