2015-06-22parse-options: move unsigned long option parsing out of pack-objects.cLibravatar Charles Bailey1-0/+3
The unsigned long option parsing (including 'k'/'m'/'g' suffix parsing) is more widely applicable. Add support for OPT_MAGNITUDE to parse-options.h and change pack-objects.c use this support. The error behavior on parse errors follows that of OPT_INTEGER. The name of the option that failed to parse is reported with a brief message describing the expect format for the option argument and then the full usage message for the command invoked. This differs from the previous behavior for OPT_ULONG used in pack-objects for --max-pack-size and --window-memory which used to display the value supplied in the error message and did not display the full usage message.

2015-06-22test-parse-options: update to handle negative intsLibravatar Charles Bailey1-1/+1
Fix the printf specification to treat 'integer' as the signed type that it is and add a test that checks that we parse negative option arguments. Signed-off-by: Charles Bailey <cbailey32@bloomberg.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-03-31parse-options: remove unused OPT_SET_PTRLibravatar Marat Radchenko1-2/+0
OPT_SET_PTR was never used since its creation at db7244bd (parse-options new features., 2007-11-07). Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-03-31parse-options: add cast to correct pointer type to OPT_SET_PTRLibravatar Junio C Hamano1-1/+1
Do not force users of OPT_SET_PTR to cast pointer to correct underlying pointer type by integrating cast into OPT_SET_PTR macro. Cast is required to prevent 'initialization makes integer from pointer without a cast' compiler warning. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-03-31MSVC: fix t0040-parse-options crashLibravatar Marat Radchenko1-1/+1
On 64-bit MSVC, pointers are 64 bit but `long` is only 32. Thus, casting string to `unsigned long`, which is redundand on other platforms, throws away important bits and when later cast to `intptr_t` results in corrupt pointer. This patch fixes test-parse-options by replacing harming cast with correct one. Signed-off-by: Marat Radchenko <marat@slonopotamus.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-04-28sparse: Fix mingw_main() argument number/type errorsLibravatar Ramsay Jones1-2/+2
Sparse issues 68 errors (two errors for each main() function) such as the following: SP git.c git.c:510:5: error: too many arguments for function mingw_main git.c:510:5: error: symbol 'mingw_main' redeclared with different type \ (originally declared at git.c:510) - different argument counts The errors are caused by the 'main' macro used by the MinGW build to provide a replacement main() function. The original main function is effectively renamed to 'mingw_main' and is called from the new main function. The replacement main is used to execute certain actions common to all git programs on MinGW (e.g. ensure the standard I/O streams are in binary mode). In order to suppress the errors, we change the macro to include the parameters in the declaration of the mingw_main function. Unfortunately, this change provokes both sparse and gcc to complain about 9 calls to mingw_main(), such as the following: CC git.o git.c: In function 'main': git.c:510: warning: passing argument 2 of 'mingw_main' from \ incompatible pointer type git.c:510: note: expected 'const char **' but argument is of \ type 'char **' In order to suppress these warnings, since both of the main functions need to be declared with the same prototype, we change the declaration of the 9 main functions, thus: int main(int argc, char **argv) Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-02-26test-parse-options: convert to OPT_BOOL()Libravatar René Scharfe1-4/+8
Introduce OPT_BOOL() to test-parse-options and add some tests for these "true" boolean options. Rename OPT_BOOLEAN to OPT_COUNTUP and OPTION_BOOLEAN to OPTION_COUNTUP as well. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-09-28parseopt: add OPT_NOOP_NOARGLibravatar René Scharfe1-0/+1
Add OPT_NOOP_NOARG, a helper macro to define deprecated options in a standard way. The help text is taken from the no-op option -r of git revert. The callback could be made to emit a (conditional?) warning later. And we could also add OPT_NOOP (requiring an argument) etc. as needed.

2009-09-29parse-opt: ignore negation of OPT_NONEG for ambiguity checksLibravatar Andreas Schwab1-0/+5
parse_long_opt always matches both --opt and --no-opt for any option "opt", and only get_value checks whether --no-opt is actually valid. Since the options for git branch contains both "no-merged" and "merged" there are two matches for --no-merge, but no exact match. With this patch the negation of a NONEG option is rejected earlier, but it changes the error message from "option `no-opt' isn't available" to "unknown option `no-opt'".

2009-06-20Fix various sparse warnings in the git source codeLibravatar Linus Torvalds1-2/+2
There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

2009-05-25parse-opts: add OPT_FILENAME and transition builtinsLibravatar Stephen Boyd1-1/+5
Commit dbd0f5c (Files given on the command line are relative to $cwd, 2008-08-06) introduced parse_options_fix_filename() as a minimal fix. OPT_FILENAME is intended to be a more robust fix for the same issue. OPT_FILENAME and its associated enum OPTION_FILENAME are used to represent filename options within the parse options API. This option is similar to OPTION_STRING. If --no is prefixed to the option the filename is unset. If no argument is given and the default value is set, the filename is set to the default value. The difference is that the filename is prefixed with the prefix passed to parse_options() (or parse_options_start()). Update git-apply, git-commit, git-fmt-merge-msg, and git-tag to use OPT_FILENAME with their filename options. Also, rename parse_options_fix_filename() to fix_filename() as it is no longer extern.

2009-05-25parse-opts: prepare for OPT_FILENAMELibravatar Stephen Boyd1-1/+1
To give OPT_FILENAME the prefix, we pass the prefix to parse_options() which passes the prefix to parse_options_start() which sets the prefix member of parse_opts_ctx accordingly. If there isn't a prefix in the calling context, passing NULL will suffice. Signed-off-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-05-09parseopt: add PARSE_OPT_NODASHLibravatar René Scharfe1-0/+2

2009-05-09parseopt: add OPT_NEGBITLibravatar René Scharfe1-0/+1
Add OPTION_NEGBIT and OPT_NEGBIT, mirroring OPTION_BIT and OPT_BIT. OPT_NEGBIT can be used together with OPT_BIT to define two options that cancel each other out. Note: this patch removes the reminder from the test script because it adds a test for --no-or4 and there already was one for --or4.

2008-07-30Fix test-parse-options "integer" testLibravatar Junio C Hamano1-3/+5
OPT_INTEGER() works on an integer, not on an unsigned long. On a big endian architecture with long larger than int, integer test gives bogus results because of this bug. Reported by H.Merijn Brand in HP-UX 64-bit environment. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-06-22Extend parse-options test suiteLibravatar Stephan Beyer1-4/+35
This patch serves two purposes: 1. test-parse-option.c should be a more complete example for the parse-options API, and 2. there have been no tests for OPT_CALLBACK, OPT_DATE, OPT_BIT, OPT_SET_INT and OPT_SET_PTR before.

2008-01-26parse-options: catch likely typo in presense of aggregated options.Libravatar Pierre Habouzit1-0/+1
If options are aggregated, and that the whole token is an exact prefix of a long option that is longer than 2 letters, reject it. This is to prevent a common typo: $ git commit -amend to get interpreted as "commit all with message 'end'". The typo check isn't performed if there is no aggregation, because the stuck form is the recommended one. If we have `-o` being a valid short option that takes an argument, and --option a long one, then we _MUST_ accept -option as "'o' option with argument 'ption'", which is our official recommended form.
