* [PATCH 6/8] Makefile: add USE_WILDMATCH to use wildmatch as fnmatch
From: Nguyễn Thái Ngọc Duy @ 2012-12-22 7:57 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1356163028-29967-1-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 5/8] test-wildmatch: add "perf" command to compare wildmatch and fnmatch
From: Nguyễn Thái Ngọc Duy @ 2012-12-22 7:57 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1356163028-29967-1-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 2/8] wildmatch: rename constants and update prototype
From: Nguyễn Thái Ngọc Duy @ 2012-12-22 7:57 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1356163028-29967-1-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 4/8] wildmatch: support "no FNM_PATHNAME" mode
From: Nguyễn Thái Ngọc Duy @ 2012-12-22 7:57 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <1356163028-29967-1-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 0/8] fnmatch replacement step 1
From: Nguyễn Thái Ngọc Duy @ 2012-12-22 7:57 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
This series makes wildmatch compatible with fnmatch, at least for
FNM_CASEFOLD and FNM_PATHNAME. This makes it possible to use wildmatch
as a fnmatch replacement. The replacement is optional and turned on via
USE_WILDMATCH.
Step 2 would be turn USE_WILDMATCH by default and remove
compat/fnmatch. We can leave it for now until we are certain we don't
introduce any kind of regressions.
Measurement is performed to see how wildmatch compete with
fnmatch(es). I was surprised that my glibc version is even slower than
compat/fnmatch. For more details, see 5/8. wildmatch is faster (about
20%) in most cases. It is slower in '*/*/*' tests both with and without
FNM_PATHNAME. 7/8 and 8/8 fix that, making wildmatch fastest in all
(tested) cases.
I'd appreciate if people test it with more patterns (both weird and
commonly used) against different fnmatch versions and turn on
USE_WILDMATCH to see if we need to fix something else, both correctness
and performance. So far I'm convinced that the replacement is a good
thing to do.
The series requires nd/wildmatch, obviously.
Nguyễn Thái Ngọc Duy (8):
compat/fnmatch: respect NO_FNMATCH* even on glibc
wildmatch: rename constants and update prototype
wildmatch: make dowild() take arbitrary flags
wildmatch: support "no FNM_PATHNAME" mode
test-wildmatch: add "perf" command to compare wildmatch and fnmatch
Makefile: add USE_WILDMATCH to use wildmatch as fnmatch
wildmatch: make a special case for "*/" with FNM_PATHNAME
wildmatch: advance faster in <asterisk> + <literal> patterns

Back then when I was converting some repositories to git and I also
wrote a quick testsuite for cvsps in an attempt to fix the bugs but gave
up. That was the point when I wrote about cvsimports limitations in the

* Missing Refs after Garbage Collection
From: Earl Gresh @ 2012-12-22 1:41 UTC (permalink / raw)
To: git
Hi-
I have observed that after running GC, one particular git repository ended up with some missing refs in the refs/changes/* namespace the Gerrit uses for storing patch sets. The refs were valid and should not have been pruned. Concerned about loosing data, GC is still enabled but ref packing is turned off. Now the number of refs has grown to the point that it's causing performance problems when cloning the project.
Is anyone familiar with git gc deleting valid references? I'm running git version 1.7.8. Have there been any patches in later git releases that might address this issue ( if it is a git problem )?
Thanks

From: Junio C Hamano @ 2012-12-21 23:59 UTC (permalink / raw)
To: git
Here are the topics that have been cooking. Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.
I'll do another rc (hopefully final) for this cycle tomorrow, with
documentation updates that are already in 'master'. The toolchain
to prepare preformatted documentation pages in HTML/man formats have
been updated to the latest AsciiDoc (from 8.5.2 to 8.6.8), and I'd
appreciate it if people can report possible regressions (I already
know the updated toolchain fixes the pretty-quotes that appear in
some pages, e.g. "git fast-import", look for "Here <name").

* jc/maint-name-rev (2012-09-17) 7 commits
- describe --contains: use "name-rev --algorithm=weight"
- name-rev --algorithm=weight: tests and documentation
- name-rev --algorithm=weight: cache the computed weight in notes
- name-rev --algorithm=weight: trivial optimization
- name-rev: --algorithm option
- name_rev: clarify the logic to assign a new tip-name to a commit
- name-rev: lose unnecessary typedef
"git name-rev" names the given revision based on a ref that can be
reached in the smallest number of steps from the rev, but that is
not useful when the caller wants to know which tag is the oldest one
that contains the rev. This teaches a new mode to the command that
uses the oldest ref among those which contain the rev.
I am not sure if this is worth it; for one thing, even with the help
from notes-cache, it seems to make the "describe --contains" even
slower. Also the command will be unusably slow for a user who does
not have a write access (hence unable to create or update the
notes-cache).
Stalled mostly due to lack of responses.

- git add: notice removal of tracked paths by default
"git add dir/" updated modified files and added new files, but does

- Teach clone to set remote.default.
- Teach "git remote" about remote.default.
- Teach remote.c about the remote.default configuration setting.
- Rename remote.c's default_remote_name static variables.
When the user does not specify what remote to interact with, we
often attempt to use 'origin'. This can now be customized via a
configuration variable.
Expecting a re-roll.
"The first remote becomes the default" bit is better done as a

What Shawn said is technically correct, but do not read it as "we
know what protocol update we want at the network level, but we
haven't got around implementing it".
It is unclear what it means to send symrefs across repositories
(rather, what we want it to mean). In that sense, the reality is
closer to the latter of your choices.
There are three primary kinds of symrefs to consider:
* worktree/.git/HEAD is meant to point at the branch that is
currently checked out. This is designed to be under sole control
of the person who is working in such a repository and the outside
people have no business knowing which branch he happens to be
working on at this very moment (it can change the next minute).
* worktree/.git/refs/remotes/$name/HEAD is meant to point at the
remote-tracking branch of the named remote (e.g. 'origin') the
local user is interested in, to let "git checkout -b topic
origin" work, instead of a longer "git checkout -b topic
origin/master".
* bare.git/HEAD is meant to point at the "primary" branch at a
bare, distribution repository nobody works in directly. The
branch pointed at by the symref rarely, if ever, changes.
Nobody will imagine flipping worktree/.git/HEAD from outside by
pushing into it (unless you are trying to pull a prank on the user
who is working in that repository). Also, nobody would want to
update this symref by fetching from outside. So we won't have to
consider updating the first kind in the following discussion.
It is unlikely that anybody sane wants to update the remote-tracking
worktree/.git/refs/remotes/origin/HEAD from outside by pushing.
It *may* make sense to update it upon fetching, though, in some
cases. You first clone from bare.git/HEAD and learn [*1*] that the
primary branch at the time of cloning was 'master', and
remote/origin/HEAD in your repository is set to point at
origin/master. Now the upstream designates a different branch as
the primary (perhaps 'trunk'), and you may want your next "git
fetch" to repoint your remote/origin/HEAD to point at
'remote/origin/trunk'.
However, even this one is not unconditionally a good idea. The
branch you are interested in might be different from what your
remote designates as its primary branch in the first place. You may
for example want to follow along 'next' after cloning from me. E.g.
$ git clone git://git.kernel.org/pub/scm/git/git.git git
$ cd git
$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/next
It is not clear if it is a good idea to allow "git fetch" to repoint
your remotes/origin/HEAD to whatever I chose to point my HEAD at.
So for the second kind, pushing is irrelevant, and fetching is
"perhaps sometimes it may make sense".
I think that the only one and a half sensible use cases that
unconditionally make sense to update symrefs across repositories are
to update bare.git/HEAD symref:
- update bare.git/HEAD of a repository that is a local mirror of a
more authoritative repository with "git fetch --mirror", in which
case you do want to follow what branch is designated as the
primary by the project you are mirroring from;
- update bare.git/HEAD from outside by some means to change which
branch is the primary one for the project. Only because your
hosting site does not give you an easy way to do so, pushing from
another repository that happens to point its HEAD at a different
branch seems to be one plausible way to do so, but that does not
have to be the only way.

hi Dennis,
In general your plan looks good. Note that you don't actually need the
Eclipse plugin at all, it just makes it possible to do git operations
while in your IDE. Most people will, even if they have the plugin,
still use the full client as it provides a lot more power and
flexibility. Use whatever you need to, and extend your toolset when
required.
Also, the leap from central repository on Linux to a clone on Windows
needs a little more thought. Will you set up a git server? Access the
central repository over ssh? A shared drive? Many people use a web
service (such as Bitbucket or GitHub) for this purpose as it becomes
easier to manage. You can then have a clone on the Linux box as well
as the Windows box.

You want to look into the different hooks available, most notable the
post-receive hook. There are also build servers that can monitor a
repository and build whenever it sees a new commit (Jenkins and Bamboo
are two I know of).

You don't need to install it, but there is no harm in it. If you ever
start doing a build from the linux box and decide you have the wrong
version of your code, it would be useful to have git installed so you
can checkout the right version. Installing git is quick and painless,
however, so you can cross that bridge once you get to it.

My knee-jerk reaction is that, while it might make sense to give an
option to allow users to use a dedicated directory per branch, I am
not interested in that form; especially the part that lets the users too
long a rope to hang themselves with by allowing an arbitrary shell
expansions goes against my taste.
But you *can* prove me wrong; read on.

You got it backwards, just like many other new people who come and go on
this list. If something is very useful, you'd work on it even if the result may
not appear immediately in the upstream, and you'd keep maintaining a local
fork so that you can keep benefiting from it, once you have written such a
useful feature (whatever it is). If even the original "itch-holder"
does not think
that the benefit from his change outweighs the cost of such an effort, why
should *I* carry it in my tree?
The goal of a contributor who comes up with an idea, gets "It doesn't sound
like a good idea" during the review but disagrees and believes in his idea
ought to be to prove the reviewer(s) wrong by polishing the idea and the
implementation so much that the upstream comes begging for your change ;-)
The core part of the change to add --reroll $n option should be straight-forward
and will involve a few functions in builtin/log.c, but the existing
code is so badly
structured that it probably needs a couple of "preparatory steps" patch to clean
up the API between internal functions on that codepath, before the real change
can be made, I think.

cvs2svn version 2.0 (Aug 2007) totally changed how cvs2svn deduces
changesets. Any results from before that are utterly irrelevant to
modern times.
The changes between version 2.0 and version 2.4 (Sep 2012) have done a
lot more to improve the quality of the conversion. The state of the art
is far beyond what it was four years ago.

Yes, we have a rather extensive test suite that includes lots of CVS
perversions. See run-tests.py and the CVS repositories under test-data.
Unfortunately, the tests mostly cover only 2svn conversions, but since
most of the tricky work is in the common code that infers the CVS
history, cvs2git benefits from the tests too.
This discussion is getting pretty cvs2svn-specific, so we should
probably move it over to the cvs2svn-dev mailing list.

You are quite right, of course, though in many useful cases they are the
same. But I guess I should just buck myself up for the new orthodoxy :-)

There is no support for symbolic references in the network protocol,
so they cannot currently be shared by git push or git fetch.

That is not an off-topic at all, but is the crux of "diff A..B" being
a hysterical raisins.
It is parsed as and converted to "diff ^A B" by the revision command
line parser in
setup_revisions(), and the caller *guesses* what the command line
originally said by
inspecting that there are two revs in rev.pending[] array, the first
one is negative and
the second one is positive, to infer that the user typed "diff A..B"
and then finally
decides to compare A and B.
This was done before we introduced rev.cmdline_info to record what was
given from
the command line to result in the set of commits in rev.pending array.
If we were
writing "git diff" UI from scratch today, we wouldn't be looking at
rev.pending but
would be looking at rev.cmdline_info and we can differenciate between
"A B", "^A B",
and "A..B" (and reject the latter two as nonsense).

Well, it has been at least four years since I ran it on anything.
Maybe that counts as old.
I'm willing to believe it's working better now, but I've had to deal
with geological strata of nastiness older versions produced in various
Subversion repositories (cleaning up that crud was a major motivation
for reposurgeon) and I'm fairly sure I haven't seen the last such
fossils. Every sufficiently old Subversion repository seems to have
few.

I can't be specific now, but that may change shortly. I'm putting
together a test suite for cvsps with the specific intention of
capturing as many odd corner cases as I can. (I just finished writing
a small Python framework for expressing interleaved CVS command
sequences on multiple checkouts in a way that can be easily run.)
It wouldn't be difficult for me to test whether these break cvs2svn.
You've established that someone over there is paying attention, so
I'll do that, I guess.
I'm willing to share my test suite as well. Do you have your own zoo
of odd cases I could test on?

I think it is a good idea to reduce the things one have to do by hand.
I, too, was thinking something similar, with a -v$n option.
And, from these few days I have started to follow the mailing list, it
seems that '[PATCH v$n'] is the standard practice.
By the way, I would also like to be able to set the default value for
the --output option in config file; something like:
[format]
output = +mp/$(git symbolic-ref --short HEAD)
where the string will be processed by the shell:
sh -c 'printf "+mp/$(git symbolic-ref --short HEAD)'"
Note that printf is POSIX, and the standard suggests to use it instead
of echo:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html
I have read the affected source code, and it should not be too hard.
What do you think?
I should be able to hack the patch in the weekend, but I'm not sure it
will be accepted.

Off topic: I also find it hard to wrap my head around what diffing

running it, it seems to be the same as diffing against a positive one.

The problem with this, to me, if it wasn't clear, is that "git log
A..B" shows you is new _since B branched off from A_, while "git diff
A..B" shows you what has changed _between A and B_.

And making it unavailable in contexts where the command was not
specifically implemented to support it. I'm sure there are many
scripts out there that use "git ... $(git merge-base A B) ..." that
could be simplified if rev-parse could resolve a merge base.

The primary problem with git-subtree was that I ended up with a temporary
file directory containing 100+K files, which I tracked back to being used
to manage the commit-to-tree mapping. On Windows, at least, that literally
slowed down the process to a crawl.

No, it is not different. However, my tool will use RAM, not diskspace to
manage information.
