2014-03-24rev-parse --parseopt: option argument name hintsIlya Bobyr
Built-in commands can specify names for option arguments when usage text is generated for a command. sh based commands should be able to do the same. Option argument name hint is any text that comes after [*=?!] after the argument name up to the first whitespace. Signed-off-by: Ilya Bobyr <> Signed-off-by: Junio C Hamano <>

"git rev-parse --default" without the required option argument did not diagnose it as an error. * ds/rev-parse-required-args: rev-parse: check i before using argv[i] against argc
2014-01-28rev-parse: check i before using argv[i] against argcDavid Sharp
The --prefix, --default, and --resolve-git-dir options to git-rev-parse require an argument, but when given no argument, the code uses the NULL read from argv[argc] without checking, leading to a segfault. Instead, check first and die() with an error message. Signed-off-by: David Sharp <> Signed-off-by: Junio C Hamano <>

2013-12-09rev-parse: be more careful with munging argumentsJeff King
When rev-parse looks at whether an argument like "" or "foobar^@" is a difference or parent-shorthand, it internally munges the arguments so that it can pass the individual rev arguments to get_sha1(). However, we do not consistently un-munge the result. For cases where we do not match (e.g., "doesnotexist..HEAD"), we would then want to try to treat the argument as a filename. try_difference gets() this right, and always unmunges in this case. However, try_parent_shorthand() never unmunges, leading to incorrect error messages, or even incorrect results: $ git rev-parse foobar^@ foobar fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' $ >foobar $ git rev-parse foobar^@ foobar For cases where we do match, neither function unmunges. This does not currently matter, since we are done with the argument. However, a future patch will do further processing, and this prepares for it. In addition, it's simply a confusing interface for some cases to modify the const argument, and others not to.

2013-12-09rev-parse: correctly diagnose revision errors before "--"Jeff King
Rev-parse understands that a "--" may separate revisions and filenames, and that anything after the "--" is taken as-is. However, it does not understand that anything before the token must be a revision (which is the usual rule implemented by the setup_revisions parser). Since rev-parse prefers revisions to files when parsing before the "--", we end up with the correct result (if such an argument is a revision, we parse it as one, and if it is not, it is an error either way). However, we misdiagnose the errors: $ git rev-parse foobar -- >/dev/null fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' $ >foobar $ git rev-parse foobar -- >/dev/null fatal: bad flag '--' used after filename In both cases, we should know that the real error is that "foobar" is meant to be a revision, but could not be resolved.

2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Christian Couder
Leaving only the function definitions and declarations so that any new topic in flight can still make use of the old functions, replace existing uses of the prefixcmp() and suffixcmp() with new API functions. The change can be recreated by mechanically applying this: $ git grep -l -e prefixcmp -e suffixcmp -- \*.c | grep -v strbuf\\.c | xargs perl -pi -e ' s|!prefixcmp\(|starts_with\(|g; s|prefixcmp\(|!starts_with\(|g; s|!suffixcmp\(|ends_with\(|g; s|suffixcmp\(|!ends_with\(|g; ' on the result of preparatory changes in this series.

2013-10-31rev-parse --parseopt: add the --stuck-long modeNicolas Vigier
Add the --stuck-long option to output the options in their long form if available, and with their arguments stuck. Contrary to the default form (non stuck arguments and short options), this can be parsed unambiguously when using options with optional arguments : - in the non stuck form, when an option is taking an optional argument you cannot know if the next argument is its optional argument, or the next option. - the long options form allows to differentiate between an empty argument '--option=' and an unset argument '--option', which is not possible with short options.

2013-07-22rev-parse: remove restrictions on some optionsJohn Keeping
The "--local-env-vars" and "--resolve-git-dir" arguments to git-rev-parse are currently only handled if they appear first on the command line (in the case of "--local-env-vars", only if it is the only argument). While it may not make sense to use these options when any others are specified, there is no reason for this restriction and it might confuse users if these arguments appear to be ignored. There is no need for any documentation change here as the restrictions on these options are not documented. Signed-off-by: John Keeping <> Signed-off-by: Junio C Hamano <>
2013-06-17rev-parse: add --prefix optionJohn Keeping
This makes 'git rev-parse' behave as if it were invoked from the specified subdirectory of a repository, with the difference that any file paths which it prints are prefixed with the full path from the top of the working tree. This is useful for shell scripts where we may want to cd to the top of the working tree but need to handle relative paths given by the user on the command line.

Either end of revision range operator can be omitted to default to HEAD, as in "origin.." (what did I do since I forked) or "..origin" (what did they do since I forked). But the current parser interprets ".." as an empty range "HEAD..HEAD", and worse yet, because ".." does exist on the filesystem, we get this annoying output: $ cd Documentation/howto $ git log .. ;# give me recent commits that touch Documentation/ area. fatal: ambiguous argument '..': both revision and filename Use '--' to separate filenames from revisions Surely we could say "git log ../" or even "git log -- .." to disambiguate, but we shouldn't have to.

2012-06-18verify_filename(): ask the caller to chose the kind of diagnosisMatthieu Moy
verify_filename() can be called in two different contexts. Either we just tried to interpret a string as an object name, and it fails, so we try looking for a working tree file (i.e. we finished looking at revs that come earlier on the command line, and the next argument must be a pathname), or we _know_ that we are looking for a pathname, and shouldn't even try interpreting the string as an object name. For example, with this change, we get: $ git log COPYING HEAD:inexistant fatal: HEAD:inexistant: no such path in the working tree. Use '-- <path>...' to specify paths that do not exist locally. $ git log HEAD:inexistant fatal: Path 'inexistant' does not exist in 'HEAD' Signed-off-by: Matthieu Moy <> Signed-off-by: Junio C Hamano <>

2011-03-23revision.c: introduce --min-parents and --max-parents optionsMichael J Gruber
Introduce --min-parents and --max-parents options which limit the revisions to those commits which have at least (or at most) that many commits, where negative arguments for --max-parents= denote infinity (i.e. no upper limit). In particular: --max-parents=1 is the same as --no-merges; --min-parents=2 is the same as --merges; --max-parents=0 shows only roots; and --min-parents=3 shows only octopus merges Using --min-parents=n and --max-parents=m with n>m gives you what you ask for (i.e. nothing) for obvious reasons, just like when you give --merges (show only merge commits) and --no-merges (show only non-merge commits) at the same time. Also, introduce --no-min-parents and --no-max-parents to do the obvious thing for convenience. We compute the number of parents only when we limit by that, so there is no performance impact when there are no limiters. Signed-off-by: Michael J Gruber <> Signed-off-by: Junio C Hamano <>

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
