[PATCH 00/21] "struct pathspec" conversion

[PATCH 00/21] "struct pathspec" conversion

[Nguyễn Thái Ngọc Duy]

This is another step towards the pathspec unification. This series
introduces a get_pathspec() alternative: parse_pathspec(). The new
function intializes struct pathspec directly. Many builtin commands
(except mv) are converted to use this function. As a result, struct
pathspec is used from the start for many commands.

The next step would be dealing with pathspec manipulation code blocks
that use "raw" field, init_pathspec or get_pathspec(). add.c, dir.c,
rm.c and mv.c are hot places. And perhaps move pathspec code from
dir.c and setup.c to pathspec.c after as/check-ignore enters "master".

This series shares a patch (the first one) with nd/pathspec-wildcard. I
put the patch in the series to avoid dependency.

This series also disables wildcards in the prefix part, but it's only
effective in combination with nd/pathspec-wildcard. And of course it's
not fully effective until all "raw" use is eliminated.

Nguyễn Thái Ngọc Duy (21):
  pathspec: save the non-wildcard length part
  Add parse_pathspec() that converts cmdline args to struct pathspec

[PATCH 01/21] pathspec: save the non-wildcard length part

[Nguyễn Thái Ngọc Duy]

We mark pathspec with wildcards with the field use_wildcard. We
could do better by saving the length of the non-wildcard part, which
can be used for optimizations such as f9f6e2c (exclude: do strcmp as
much as possible before fnmatch - 2012-06-07).

[PATCH 02/21] Add parse_pathspec() that converts cmdline args to struct pathspec

[Nguyễn Thái Ngọc Duy]

Currently to fill a struct pathspec, we do:

   const char **paths;
   paths = get_pathspec(prefix, argv);
   ...
   init_pathspec(&pathspec, paths);

"paths" can only carry bare strings, which loses information from
command line arguments such as pathspec magic or the prefix part's
length for each argument.

parse_pathspec() is introduced to combine the two calls into one. The
plan is gradually replace all get_pathspec() and init_pathspec() with
parse_pathspec(). get_pathspec() now becomes a thin wrapper of
parse_pathspec().

parse_pathspec() allows the caller to reject the pathspec magics that
it does not support. When a new pathspec magic is introduced, we can
enable it per command after making sure that all underlying code has no
problem with the new magic.

"flags" parameter is currently unused. But it would allow callers to
pass certain instructions to parse_pathspec, for example forcing
literal pathspec when no magic is used.

With the introduction of parse_pathspec, there are now two functions
that can initialize struct pathspec: init_pathspec and
parse_pathspec. Any semantic changes in struct pathspec must be
reflected in both functions. init_pathspec() will be phased out in
favor of parse_pathspec().

[PATCH 03/21] pathspec: make sure the prefix part is wildcard-clean

[Nguyễn Thái Ngọc Duy]

Prefix is the result of Git moving back from current directory to
worktree's top directory and it has to prepend all user provided paths
so that they become relative to the new current directory. Any
wildcards in the prefix should not be treated as such because it's not
the user intention. Make sure all wildcards in the prefix part is
disabled.

[PATCH 21/21] Convert more init_pathspec() to parse_pathspec()

[Nguyễn Thái Ngọc Duy]

init_pathspec() was introduced to work with the result from
get_pathspec(). init_pathspec() will be removed eventually after
parse_pathspec() takes over, so that there is only place that
initializes struct pathspec.

Yay!

Thanks, looking forward to reading it through.

This is wrong (so much for the last-minute patch). Prefix length
depends on actual pathspec (e.g. abc, ../abc and ../../abc use
different prefix length). This patch should be discarded (it does not
have any real impacts anyway).

Re: [PATCH 02/21] Add parse_pathspec() that converts cmdline args to struct pathspec

When working with the old get_pathspec(), I remember wondering if a
flag switching between "no argument -> prefix pathspec" and "no
argument -> no pathspec" would be worthwhile. I think e.g. 'add' and
'clean' would use the former , while 'reset' and 'commit' would use
the latter. Since you're now changing all the callers of
get_pathspec(), it seems like the perfect time to ask this question.
What do you think?

Yes that'll simplify the call sites. Will do.
