* ref-filter: add --no-contains option to tag/branch/for-each-refÆvar Arnfjörð Bjarmason2017-03-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the tag, branch & for-each-ref commands to have a --no-contains option in addition to their longstanding --contains options. This allows for finding the last-good rollout tag given a known-bad <commit>. Given a hypothetically bad commit cf5c7253e0, the git version to revert to can be found with this hacky two-liner: (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') | sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10 With this new --no-contains option the same can be achieved with: git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10 As the filtering machinery is shared between the tag, branch & for-each-ref commands, implement this for those commands too. A practical use for this with "branch" is e.g. finding branches which were branched off between v2.8.0 and v2.10.0: git branch --contains v2.8.0 --no-contains v2.10.0 The "describe" command also has a --contains option, but its semantics are unrelated to what tag/branch/for-each-ref use --contains for. A --no-contains option for "describe" wouldn't make any sense, other than being exactly equivalent to not supplying --contains at all, which would be confusing at best. Add a --without option to "tag" as an alias for --no-contains, for consistency with --with and --contains. The --with option is undocumented, and possibly the only user of it is Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's trivial to support, so let's do that. The additions to the the test suite are inverse copies of the corresponding --contains tests. With this change --no-contains for tag, branch & for-each-ref is just as well tested as the existing --contains option. In addition to those tests, add a test for "tag" which asserts that --no-contains won't find tree/blob tags, which is slightly unintuitive, but consistent with how --contains works & is documented.

* parse-options: add OPT_NONEG to the "contains" optionÆvar Arnfjörð Bjarmason2017-03-241-2/+2
| | | | | | | | | | | | | | Add the OPT_NONEG flag to the "contains" option and its hidden synonym "with". Since this was added in commit 694a577519 ("git-branch --contains=commit", 2007-11-07) giving --no-{contains,with} hasn't been an error, but has emitted the help output since filter.with_commit wouldn't get set. Now git will emit "error: unknown option `no-{contains,with}'" at the top of the help output.

* | parse_options: allocate a new array when concatenatingjk/parse-options-concatJeff King2016-07-061-1/+1
|/ | | | | | | | | | | | | | | | 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>

|/ | | | | | | | | | | | | | | | | | | 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.

Commit 5ded807 prevents us using this macro with clang, since clang's -Wunused-value is smart enough to realize that the constant "-1" is useless in some contexts. However, since the last commit puts the constant behind an inline function call, this is enough to prevent the -Wunused-value warning on both modern gcc and clang. So we can now re-enable the macro when compiling with clang. Tested with clang 3.3, 3.4, and 3.5. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This works well for code like: return error(...); but the "-1" is superfluous in code that just calls error() without caring about the return value. In older versions of gcc, that was fine, but gcc 4.9 complains with -Wunused-value. We can work around this by encapsulating the constant return value in a static inline function, as gcc specifically avoids complaining about unused function returns unless the function has been specifically marked with the warn_unused_result attribute. We also use the same trick for config_error_nonbool and opterror, which learned the same error technique in a469a10.

We limit the use of these macros to __GNUC__, since gcc is the primary beneficiary of the new information, and because we use GNU features for handling variadic macros. However, clang also defines __GNUC__, but generates warnings with -Wunused-value when these macros are used in a void context, because the constant "-1" ends up being useless. Gcc does not complain about this case (though it is unclear if it is because it is smart enough to see what we are doing, or too dumb to realize that the -1 is unused). We can squelch the warning by just disabling these macros when clang is in use.

* | silence some -Wuninitialized false positivesJeff King2012-12-151-0/+4
|/ | | | | | | | | | | | | | | | | | | | There are a few error functions that simply wrap error() and provide a standardized message text. Like error(), they always return -1; knowing that can help the compiler silence some false positive -Wuninitialized warnings. One strategy would be to just declare these as inline in the header file so that the compiler can see that they always return -1. However, gcc does not always inline them (e.g., it will not inline opterror, even with -O3), which renders our change pointless. Instead, let's follow the same route we did with error() in the last patch, and define a macro that makes the constant return value obvious to the compiler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A column option string consists of many token separated by either a space or a comma. A token belongs to one of three groups: - enabling: always, never and auto - layout mode: currently plain (which does not layout at all) - other future tuning flags git-column can be used to pipe output to from a command that wants column layout, but not to mess with its own output code. Simpler output code can be changed to use column layout code directly.

* | parse-options: remove PARSE_OPT_NEGHELPrs/no-no-no-parseoptRené Scharfe2012-02-281-4/+0
|/ | | | | | | | | | | | PARSE_OPT_NEGHELP is confusing because short options defined with that flag do the opposite of what the helptext says. It is also not needed anymore now that options starting with no- can be negated by removing that prefix. Convert its only two users to OPT_NEGBIT() and OPT_BOOL() and then remove support for PARSE_OPT_NEGHELP.

* parseopt: add OPT_NOOP_NOARGRené Scharfe2011-09-281-0/+6
| | | | | | | | | | | | 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.

* parse-options: deprecate OPT_BOOLEANJunio C Hamano2011-09-271-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is natural to expect that an option defined with OPT_BOOLEAN() could be used in this way: int option = -1; /* unspecified */ struct option options[] = { OPT_BOOLEAN(0, "option", &option, "set option"), OPT_END() }; parse_options(ac, av, prefix, options, usage, 0); if (option < 0) ... do the default thing ... else if (!option) ... --no-option was given ... else ... --option was given ... to easily tell three cases apart: - There is no mention of the `--option` on the command line; - The variable is positively set with `--option`; or - The variable is explicitly negated with `--no-option`. Unfortunately, this is not the case. OPT_BOOLEAN() increments the variable every time `--option` is given, and resets it to zero when `--no-option` is given. As a first step to remedy this, introduce a true boolean OPT_BOOL(), and rename OPT_BOOLEAN() to OPT_COUNTUP(). To help transitioning, OPT_BOOLEAN and OPTION_BOOLEAN are defined as deprecated synonyms to OPT_COUNTUP and OPTION_COUNTUP respectively. This is what db7244b (parse-options new features., 2007-11-07) from four years ago started by marking OPTION_BOOLEAN as "INCR would have been a better name". Some existing users do depend on the count-up semantics; for example, users of OPT__VERBOSE() could use it to raise the verbosity level with repeated use of `-v` on the command line, but they probably should be rewritten to use OPT__VERBOSITY() instead these days. I suspect that some users of OPT__FORCE() may also use it to implement different level of forcibleness but I didn't check. On top of this patch, here are the remaining clean-up tasks that other people can help: - Look at each hit in "git grep -e OPT_BOOLEAN"; trace all uses of the value that is set to the underlying variable, and if it can proven that the variable is only used as a boolean, replace it with OPT_BOOL(). If the caller does depend on the count-up semantics, replace it with OPT_COUNTUP() instead. - Same for OPTION_BOOLEAN; replace it with OPTION_SET_INT and arrange to set 1 to the variable for a true boolean, and otherwise replace it with OPTION_COUNTUP. - Look at each hit in "git grep -e OPT__VERBOSE -e OPT__QUIET" and see if they can be replaced with OPT__VERBOSITY(). I'll follow this message up with a separate patch as an example. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parse-options provides a variety of option behaviors, including OPTION_CALLBACK, which should take care of just about any sane behavior. All supported behaviors obey the following constraint: A --foo option can only accept (and base its behavior on) one argument, which would be the following command-line argument in the "unsticked" form. Alas, some existing git commands have options that do not obey that constraint. For example, update-index --cacheinfo takes three arguments, and update-index --resolve takes all later parameters as arguments. Introduces an OPTION_LOWLEVEL_CALLBACK backdoor to parse-options so such option types can be supported without tempting inventors of other commands through mention in the public API. Commands can set the callback field to a function accepting three arguments: the option parsing context, the option itself, and a flag indicating whether the the option was negated. When the option is encountered, that function is called to take over from get_value(). The return value should be zero for success, -1 for usage errors. Thanks to Stephen Boyd for API guidance.

| * parse-options: Don't call parse_options_check() so muchStephen Boyd2010-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | parse_options_check() is being called for each invocation of parse_options_step which can be quite a bit for some commands. The commit introducing this function cb9d398 (parse-options: add parse_options_check to validate option specs., 2009-06-09) had the correct motivation and explicitly states that parse_options_check() should be called from parse_options_start(). However, the implementation differs from the motivation. Fix it. Signed-off-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
