While I am very sympathetic to those who feel the pain, i.e. the need for something like this, I do not think this patch takes the right approach. The pain is that "git log --grep=..." can express only a limited subset of what "git grep" can express. The latter supports a very rich set of logical operations, with operators like --and and --not, and grouping, e.g. "git grep \( -e foo --or -e bar \) --and --not -e baz" (i.e. "has either foo or bar but not baz"). It also can turn the list of top-level predicates into "all of these predicates must match somewhere in the entire file" with --all-match option. None of this richness is available to "git log --grep=...". The root cause of the pain comes from the fact that it needs to share the command line parsing with the revision list commands to drive the underlying "grep" machinery, so you cannot say git log --not --grep=FIXUP because "--not" is taken as "commits reachable from revs listed after this point are to be excluded from the result" and not passed to the underlying grep machinery. The right way to do this is to somehow find a way to allow you to express the full "grep" logical operations to the command line parser that is used by the "log" family of commands. That would allow you to express something like "Show only commits that has either foo or bar and does not have baz". I am not going to advocate this exact syntax, but to illustrate the idea, if you had something like this supported: git log --grep-begin \ \( -e foo --or -e bar \) --and --not -e baz \ --grep-end by stopping the revision.c parser between --grep-{begin,end} and instead feeding the arguments to the grep expression builder, we may be able to get the full expressiveness of the logical operations offered by the grep machinery. And you shouldn't need to add any new field to grep_opt for that. All you need is a design of a new syntax and a tweak to the revision argument parser to understand the new syntax to redirect some arguments to the grep command line parser. A new option that allows you to _only_ negate without allowing you to enable other richer logical operations of the underlying grep machinery is going in a wrong direction, isn't it? > Signed-off-by: Christoph Junghans <ottxor@gentoo.org> > --- > Documentation/rev-list-options.txt | 4 ++++ > contrib/completion/git-completion.bash | 2 +- > grep.h | 3 ++- > revision.c | 4 +++- > 4 files changed, 10 insertions(+), 3 deletions(-) > > diff --git a/Documentation/rev-list-options.txt b/Documentation/rev-list-options.txt > index afccfdc..6d4671f 100644 > --- a/Documentation/rev-list-options.txt > +++ b/Documentation/rev-list-options.txt > @@ -66,6 +66,10 @@ if it is part of the log message. > Limit the commits output to ones that match all given `--grep`, > instead of ones that match at least one. > > +--invert-grep:: > + Limit the commits output to ones with log message that do not > + match the pattern specified with `--grep=<pattern>`. > + > -i:: > --regexp-ignore-case:: > Match the regular expression limiting patterns without regard to letter > diff --git a/contrib/completion/git-completion.bash b/contrib/completion/git-completion.bash > index 2fece98..914c317 100644 > --- a/contrib/completion/git-completion.bash > +++ b/contrib/completion/git-completion.bash > @@ -1425,7 +1425,7 @@ __git_log_gitk_options=" > # Options that go well for log and shortlog (not gitk) > __git_log_shortlog_options=" > --author= --committer= --grep= > - --all-match > + --all-match --invert-grep > " > > __git_log_pretty_formats="oneline short medium full fuller email raw format:" > diff --git a/grep.h b/grep.h > index 95f197a..c137103 100644 > --- a/grep.h > +++ b/grep.h > @@ -93,7 +93,8 @@ struct grep_opt { > int prefix_length; > regex_t regexp; > int linenum; > - int invert; > + int invert; /** line-wise invert match */ > + int global_invert; /** final global invert match */ > int ignore_case; > int status_only; > int name_only; > diff --git a/revision.c b/revision.c > index 75dda92..c8d4c49 100644 > --- a/revision.c > +++ b/revision.c > @@ -2011,6 +2011,8 @@ static int handle_revision_opt(struct rev_info *revs, int argc, const char **arg > grep_set_pattern_type_option(GREP_PATTERN_TYPE_PCRE, &revs->grep_filter); > } else if (!strcmp(arg, "--all-match")) { > revs->grep_filter.all_match = 1; > + } else if (!strcmp(arg, "--invert-grep")) { > + revs->grep_filter.global_invert = 1; > } else if ((argcount = parse_long_opt("encoding", argv, &optarg))) { > if (strcmp(optarg, "none")) > git_log_output_encoding = xstrdup(optarg); > @@ -2909,7 +2911,7 @@ static int commit_match(struct commit *commit, struct rev_info *opt) > (char *)message, strlen(message)); > strbuf_release(&buf); > unuse_commit_buffer(commit, message); > - return retval; > + return opt->grep_filter.global_invert ? !retval : retval; > } > > static inline int want_ancestry(const struct rev_info *revs) ^ permalink raw reply [flat|nested] 15+ messages in thread

Good point. The only interface to tweak the way the individual matches are turned into file-level match (by default, we say "any one of the clauses match, we find the file to be interesting") is "--all-match" ("all of the clauses have to trigger at least once for us to find the file interesting"), which, compared to the richer set of boolean operations at the line level, is a kludge. Offhand, short of overhauling that kludge to allow us to express "The file has to have either 'atomic' or 'all-or-none' appear somewhere, and also cannot have 'wip' anywhere", I do not think of a good way, other than adding yet another kludge on top of the "--all-match" that says "none of the clauses must trigger" to express what you want to see happen in "git log" to exclude ones that are marked with "wip", perhaps naming it "--none-match" or something.

If a file matches none of the patterns, what matches are there to show?

I missed that "-L" option. Thanks for your patience. I should have realized that this not only can be "log-only" but _should_ be "log-only". As you pointed out, when we already have "-L", trying to extend it to "grep" does not make much sense. Continuing this line of thought, as we determined that it is pointless to have this at "grep" level and it is needed only in the "log" family of commands, I would very much prefer the approach taken by your original "log --invert-grep" patch. I would further say that I prefer not to touch grep_opt at all. The new "global-invert bit" is about "we'd run the usual grep thing on the log message, and instead of filtering to only show the commits with matching message, we only show the ones with messages that do not match". That logically belongs to the revision struct that is used to interpret what the underlying grep machinery figured out, and should not have to affect the way how underlying grep machinery works. We would want a few test to make sure that we do not break the feature in the future changes. Here is an attempt. The patch would apply any commit your original "--invert-grep" option would have applied. Thanks again. -- >8 -- Subject: log: teach --invert-grep option "git log --grep=<string>" shows only commits with messages that match the given string, but sometimes it is useful to be able to show only commits that do *not* have certain messages (e.g. "show me ones that are not FIXUP commits"). Signed-off-by: Christoph Junghans <ottxor@gentoo.org> Signed-off-by: Junio C Hamano <gitster@pobox.com> --- jc: Christoph originally had the invert-grep flag in grep_opt, but because "git grep --invert-grep" does not make sense except in conjunction with "--files-with-matches", which is already covered by "--files-without-matches", I moved it to revisions structure. I think it expresses what the feature is about better to have the flag there. When the newly inserted two tests run, the history would have commits with messages "initial", "second", "third", "fourth", "fifth", "sixth" and Second", committed in this order. The first commit that does not match either "th" or "Sec" is "second", and "initial" is the one that does not match either "th" or "Sec" case insensitively.

I see you moved the two bits meant only to be useful during the review to the commit message proper. The reason why I omitted the "Originally, ..." part was because those who are reading "git log -p" output would not know what the earlier draft had. I do not mind it either way, though, so let's take this version. However, I'd have to drop gitk-git/ bit; that part of the tree is maintained separately and comes from Paul's gitk repository. I'll forward only that part of the patch to him when this feature graduates to 'master'. Thanks. ^ permalink raw reply [flat|nested] 15+ messages in thread
