René Scharfe	39ea59a257	remove unnecessary NULL check before free(3) free(3) handles NULL pointers just fine. Add a semantic patch for removing unnecessary NULL checks before calling this function, and apply it on the code base.

Michael Haggerty	ce564eb1bd	parse-options: add parse_opt_unknown_cb() Add a new callback function, parse_opt_unknown_cb(), which returns -2 to indicate that the corresponding option is unknown. This can be used to add "-h" documentation for an option that will be handled externally to parse_options().

Jeff King	023ff39b29	parse_options: allocate a new array when concatenating In exactly one callers (builtin/revert.c), we build up the options list dynamically from multiple arrays. We do so by manually inserting "filler" entries into one array, and then copying the other array into the allocated space. This is tedious and error-prone, as you have to adjust the filler any time the second array is modified (although we do at least check and die() when the counts do not match up). Instead, let's just allocate a new array. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	9 years ago
Jeff King	7a7a517a2f	parse_opt_string_list: stop allocating new strings The parse_opt_string_list callback is basically a thin wrapper to string_list_append() any string options we get. However, it calls: string_list_append(v, xstrdup(arg)); which duplicates the option value. This is wrong for two reasons: 1. If the string list has strdup_strings set, then we are making an extra copy, which is simply leaked. 2. If the string list does not have strdup_strings set, then we pass memory ownership to the string list, but it does not realize this. If we later call string_list_clear(), which can happen if "--no-foo" is passed, then we will leak all of the existing entries. Instead, we should just pass the argument straight to string_list_append, and it can decide whether to copy or not based on its strdup_strings flag. It's possible that some (buggy) caller could be relying on this extra copy (e.g., because it parses some options from an allocated argv array and then frees the array), but it's not likely. For one, we generally only use parse_options on the argv given to us in main(). And two, such a caller is broken anyway, because other option types like OPT_STRING() do not make such a copy. This patch brings us in line with them. Noticed-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	9 years ago
Karthik Nayak	9d306b5a60	parse-option: rename parse_opt_with_commit() Rename parse_opt_with_commit() to parse_opt_commits() to show that it can be used to obtain a list of commits and is not constricted to usage of '--contains' option.

Karthik Nayak	b2172fdf70	tag: libify parse_opt_points_at() Rename 'parse_opt_points_at()' to 'parse_opt_object_name()' and move it from 'tag.c' to 'parse-options'. This now acts as a common parse_opt function which accepts an objectname and stores it into a sha1_array.

Paul Tan	ffad85c599	parse-options-cb: implement parse_opt_passthru_argv() Certain git commands, such as git-pull, are simply wrappers around other git commands like git-fetch, git-merge and git-rebase. As such, these wrapper commands will typically need to "pass through" command-line options of the commands they wrap. Implement the parse_opt_passthru_argv() parse-options callback, which will reconstruct all the provided command-line options into an argv_array, such that it can be passed to another git command. This is useful for passing command-line options that can be specified multiple times.

Junio C Hamano	27ec394a97	prune: introduce OPT_EXPIRY_DATE() and use it Earlier we added support for --expire=all (or --expire=now) that considers all crufts, regardless of their age, as eligible for garbage collection by turning command argument parsers that use approxidate() to use parse_expiry_date(), but "git prune" used a built-in parse-options facility OPT_DATE() and did not benefit from the new function.

René Scharfe	6acec0380b	parseopt: add OPT_NOOP_NOARG 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.

Dmitry Ivankov	0687628466	Reduce parse-options.o dependencies Currently parse-options.o pulls quite a big bunch of dependencies. his complicates it's usage in contrib/ because it pulls external dependencies and it also increases executables size. Split off less generic and more internal to git part of parse-options.c to parse-options-cb.c. Move prefix_filename function from setup.c to abspath.c. abspath.o and wrapper.o pull each other, so it's unlikely to increase the dependencies. It was a dependency of parse-options.o that pulled many others. Now parse-options.o pulls just abspath.o, ctype.o, strbuf.o, usage.o, wrapper.o, libc directly and strlcpy.o indirectly.
