* [PATCH 1/8] Use %B for Split Subject/Body
From: David A. Greene @ 2013-01-01  3:57 UTC (permalink / raw)
  To: git; +Cc: Techlive Zheng, David A. Greene
In-Reply-To: <1357012655-24974-1-git-send-email-greened@obbligato.org>

From: Techlive Zheng <techlivezheng@gmail.com>

Use %B to format the commit message and body to avoid an extra newline
if a commit only has a subject line.

* git-subtree Patches to Apply
From: David A. Greene @ 2013-01-01  3:57 UTC (permalink / raw)
  To: git

Here are all of the patches for git-subtree that have been posted to
the mailing list that I could apply and test in a reasonable amount of
time.  These are all rebased from trunk as of tonight.

Many apologies for being *so* behind.  Work has been a bear but I'm
hoping things will ease up in the new year and I can be more regularly
active.  But still, don't expect same-day service.  :)

These are also available on branch "toupstream" via

git clone gitolite@sources.obbligato.org:git.git

and

http://sources.obbligato.org
http://sources.obbligato.org/?p=git.git;a=summary

Junio, can you apply these?  Thanks!

Do you literally mean "a path to a repository" in the above, or do
you mean "a remote that is like what is accepted by 'git fetch'"?
If you literary mean it is is a path to a git repository, you could
obviously use "cd $there && git rev-parse --git-dir" or something.

On the other hand, if you mean the command takes a remote and an
optional list of refspecs just like "git fetch" does, then I am not
sure it is a good design in the first place to allow "refspecs
only", if only to keep the interface similar to "git fetch" (you
cannot omit remote and give refspecs, as you cannot interpret
refspecs without knowing in the context of which remote they are to
be interpreted).

I would imagine you could disambiguate and default to "origin" or
something when you guessed that remote was omitted if you really
wanted to, with a syntacitical heuristics, such as "a refspec will
never have two colons in it", "a URL tends to begin with a short
alphabet word, a colon and double-slash", etc.

On the same subject of format-patch improvements, perhaps we should also:

   - Keep subject line in branch.%s.description too. No point in
     keeping writing the subject on every reroll.

   - Perhaps an option to save the current tip in reflog with reroll
     count so one can easily diff between two rerolls.

Specifying a local branch works fine, though, as does a raw commit
hash.  What do you mean by "local commit?"

I have updated the documentation and will submit it tonight or tomorrow.

Any invalid refspec should be caught early and a more useful message
will be displayed.

Fixed.

Seems to work for me.  Can you give me the command you're using when you
see the problem?

Thanks for the report!

* [PATCH v3 10/10] Makefile: add USE_WILDMATCH to use wildmatch as fnmatch
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

This is similar to NO_FNMATCH but it uses wildmatch instead of
compat/fnmatch. This is an intermediate step to let wildmatch be used
as fnmatch replacement for wider audience before it replaces fnmatch
completely and compat/fnmatch is removed.

fnmatch in test-wildmatch is not impacted by this and is the only
place that NO_FNMATCH or NO_FNMATCH_CASEFOLD remain active when
USE_WILDMATCH is set.

* [PATCH v3 09/10] wildmatch: advance faster in <asterisk> + <literal> patterns
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

Normally when we match "*X" on "abcX", we call dowild("X", "abcX"),
dowild("X", "bcX"), dowild("X", "cX") and dowild("X", "X"). Only the
last call may have a chance of matching. By skipping the text before

* [PATCH v3 08/10] wildmatch: make a special case for "*/" with FNM_PATHNAME
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)

Normally we need recursion for "*". In this case we know that it
matches everything until "/" so we can skip the recursion.

before:
wildmatch 8s 74513us

after:

Same test with compat/fnmatch:
wildmatch 8s 110763us
fnmatch   2s 980845us or 36.75% faster
wildmatch 3s 522156us

* [PATCH v3 07/10] test-wildmatch: add "perf" command to compare wildmatch and fnmatch
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

It takes a text file, a pattern, a number <n> and pathname flag. Each
line in the text file is matched against the pattern <n> times. If
"pathname" is given, FNM_PATHNAME is used.

test-wildmatch is built with -O2 and tested against glibc 2.14.1 (also
-O2) and compat/fnmatch. The input file is linux-2.6.git file list.
<n> is 2000. The complete command list is at the end.

wildmatch is beaten in the following cases. Apparently it needs some
improvement in FNM_PATHNAME case:

glibc, '*/*/*' with FNM_PATHNAME:
wildmatch 8s 1559us
fnmatch   1s 11877us or 12.65% faster

compat, '*/*/*' with FNM_PATHNAME:
wildmatch 7s 922458us
fnmatch   2s 905111us or 36.67% faster

compat, '*/*/*' without FNM_PATHNAME:
wildmatch 7s 264201us
fnmatch   2s 1897us or 27.56% faster

compat, '[a-z]*/[a-z]*/[a-z]*' with FNM_PATHNAME:
wildmatch 8s 742827us
fnmatch   0s 922943us or 10.56% faster

compat, '[a-z]*/[a-z]*/[a-z]*' without FNM_PATHNAME:
wildmatch 8s 284520us
fnmatch   0s 6936us or 0.08% faster

* [PATCH v3 06/10] wildmatch: support "no FNM_PATHNAME" mode
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

So far, wildmatch() has always honoured directory boundary and there
was no way to turn it off. Make it behave more like fnmatch() by
requiring all callers that want the FNM_PATHNAME behaviour to pass
that in the equivalent flag WM_PATHNAME. Callers that do not specify
WM_PATHNAME will get wildcards like ? and * in their patterns matched
against '/', just like not passing FNM_PATHNAME to fnmatch().

* [PATCH v3 04/10] wildmatch: rename constants and update prototype
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

- All exported constants now have a prefix WM_
- Do not rely on FNM_* constants, use the WM_ counterparts
- Remove TRUE and FALSE to follow Git's coding style
- While at it, turn flags type from int to unsigned int
- Add an (unused yet) argument to carry extra information
  so that we don't have to change the prototype again later
  when we need to pass other stuff to wildmatch

* [PATCH v3 03/10] wildmatch: replace variable 'special' with better named ones
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

'special' is too generic and is used for two different purposes.
Replace it with 'match_slash' to indicate "**" pattern and 'negated'
for "[!...]" and "[^...]".

* [PATCH v3 01/10] wildmatch: fix "**" special case
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1357008251-10014-1-git-send-email-pclouds@gmail.com>

"**" is adjusted to only be effective when surrounded by slashes, in
40bbee0 (wildmatch: adjust "**" behavior - 2012-10-15). Except that
the commit did it wrong:

1. when it checks for "the preceding slash unless ** is at the
   beginning", it compares to wrong pointer. It should have compared
   to the beginning of the pattern, not the text.

2. prev_p points to the character before "**", not the first "*". The
   correct comparison must be "prev_p < pattern" or
   "prev_p + 1 == pattern", not "prev_p == pattern".

3. The pattern must be surrounded by slashes unless it's at the
   beginning or the end of the pattern. We do two checks: one for the
   preceding slash and one the trailing slash. Both checks must be
   met. The use of "||" is wrong.

This patch fixes all above.

* [PATCH v3 00/10] fnmatch replacement
From: Nguyễn Thái Ngọc Duy @ 2013-01-01  2:44 UTC (permalink / raw)
  To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy

The first patch actually belongs to nd/wildmatch as it fixes how "**"
is only effective when it's surrounded by slashes.

Other fixes from v2 are WM_PATHNAME check is replaced by match_slash
(or "special" previously) in 8/10 and 9/10. WM_PATHNAME is only used

Ok, I used git rev-parse --verify and I have this working now.  Will
send to Junio in the batch with fixes from other folks.

Thanks for catching this!

I'm looking at implementing this but I need a bit of help from the git
experts.

git-subtree add accepts either a refspec or a path to a repository and a
refspec.  With one positional option, git-subtree add simply assumes
it's a refspec.  Is there an easy way to check whether a string is a
proper refspec?  Even better would be a way to check if a string is a
path to a git repository.

As soon as there is one patch per feature that applies cleanly to
contrib/ and testcases use the native git test facility.

These patches should be submitted to the mailing list for review.

Good idea.  I'll code it up.

I did finally see this message.  I totally admit that I've been pretty
absent.  It just happens that I have a ton of paid work to do and
voluteer work unfortunately comes last, after family and after paid
work.

For this bug I honestly don't know what is supposed to happen.  I'm
still learning the code.  It's a bit of a shell-script mess to be
honest, very hard to follow.  That's why it's still in contrib/
and will remain so for a while.

I am more than happy for others to jump in and help out.  I'm not a
gatekeeper.
