Wouldn't this break creating a bugfix topic branch based on an earlier
revision of the repo? I wouldn't want such a branch to automatically give me
the latest submodules.
I'd prefer to have floating be explicitly configured on a per-branch (or
per-branch-glob) basis. So in addition to what Jens described yesterday [1]
to configure an individual submodule's floating branch, I suggest there also
be a new section in the .gitmodules file for configuring the super-repo's
floating branches, e.g.
[super]
floaters = refs/heads/master refs/heads/dev*
[submodule "Sub1"]
path = foo/bar
branch = maint
url = ...
[submodule "Sub2"]
path = other/place
url = ...
This would mean that whenever the super-repo checks out either the "master"
branch or a branch whose name starts with "dev" (assuming recursive checkouts
are on):
* The Sub1 submodule automatically checks out the tip of its
"maint" branch.
* The Sub2 submodule (lacking a "branch" variable) would not float
and would check out the commit recorded in the super-repo.
A super-repo recursive-checkout that doesn't match a floaters pattern would
work in the regular, non-floating way.

* [PATCH] gitk: fix the display of files when filtered by path
From: Pat Thoyts @ 2011-12-13 16:50 UTC (permalink / raw)
To: Git; +Cc: Paul Mackerras, msysGit, Johannes Schindelin
Launching 'gitk -- .' or 'gitk -- ..\t' restricts the display to files
under the given directory but the file list is left empty. This is because
the path_filter function fails to match the filenames which are relative
to the working tree to the filter which is filessytem relative.
This solves the problem by making both names fully qualified filesystem
paths before performing the comparison.

If your main point is that "return l ? 1 : 0;", then a better thing to do
would be to use a well-known idiom to turn anything into a boolean, i.e.
return !!l;
and your problem is solved without any renaming (we are not talking about
any "refactoring" that changes code structure).
I've seen enough bikeshedding, so I'd stop after pointing you in the right
direction by mentioning "git grep -e '<lst>'" and "git grep -e '<elem>'".

I think this is a sane thing to do. Having thought about and
experimented a little with utf-16 in the past few months, I really don't
see how you could be disrupting anybody's workflow. utf-16 messages get
butchered so badly already; we are much better off letting the user know
of the problem as soon as possible.
It looks like we already have a check for is_utf8, and this is not
failing that check. I guess because is_utf8 takes a NUL-terminated
buffer, so it simply sees the truncated result (i.e., depending on
endianness, "foo" in utf16 is something like "f\0o\0o\0", so we check
only "f"). We could make is_utf8 take a length parameter to be more
accurate, and then it would catch this.
However, I think that's not quite what we want. We only check is_utf8 if
the encoding field is not set. And really, we want to reject NULs no
matter _which_ encoding they've set, because git simply doesn't handle
them properly.

Two nits:
1. For some reason, checking strlen(msg) seems a subtle way of looking
for NULs in a buffer. I would have found:
if (memchr(msg, '\0', msglen))
much more obvious. But perhaps it is just me. Certainly not a big
deal either way.
2. The error message could be a little friendlier. The likely reason
for NULs is a bogus encoding setting in the user's editor. We
already have a nice "your message isn't utf-8" message. Though it
does suggest setting i18n.commitencoding, which probably _isn't_
the solution here (since their encoding clearly isn't supported).
But maybe it would be nicer to say something like:
error: your commit message contains NUL characters.
hint: This is often caused by using multibyte encodings such as
hint: UTF-16. Please check your editor settings.
We could even go further and detect some common NUL-containing
encodings, but I don't think it's worth the effort.

It probably doesn't matter, because the error condition is almost
certainly just "oops, we ran out of memory". But you could also print
the name of the variable being set, which may give the user a clue to
some misconfiguration (e.g., trying to put some extremely long value
into the environment).

I wrote almost the same patch once[1], but failed to actually push it
through to acceptance. There weren't any objections, just that nobody
really cared. I think it's a reasonable thing to do. The chances of
setenv failing are very low, but the consequences could be quite bad.
There is also a call to putenv in git.c which should be checked (or
could arguably just be converted to setenv).

* [PATCH 0/3] use constants for sideband communication channels
From: iheffner @ 2011-12-13 18:28 UTC (permalink / raw)
To: git; +Cc: Jeff King, Junio C Hamano, Dave Olszewski
In order to make more clear how the different channels in sidechannel.c
are to be used, I'm proposing some macros/constants which can be used in
place of the "magic numbers" that mean little or nothing to someone not
familiar with the protocol.
In working on a script to handle archiving from a bare repository a
project which contained submodules, I had a difficult time determining
how to talk between my git-upload-archive replacement and git-archive.
It did not occur to me to look at documentation for git-send-pack or
git-receive-pack when trying to understand the communication protocol.
But looking through the code and poking at an implementation, I finally
understood that I needed to send a channel identifier to say what type
of communication I was sending. I determined that there were three
possible channels. I could easily tell that channel three (3) was for
catastrophic errors on the server side. But it was not clear what the
difference between channel 1 and channel 2 were. Because channel 2 was
the one that appeared to be read and parsed in some manner, I assumed
that this was the "important" data channel and tried sending my data on
that channel.
I was confused and frustrated when it appeared that git-archive treated
data coming from my --exec'd git-upload-archive replacement differently
than it did when receiving data from the real git-upload-archive.
Eventually I figured out that channel 1 was for data, channel 2 was for
non-fatal messages, and channel 3 was for fatal error communications.
Having comments in sidechannel.h would have helped. But constants or
macros would have helped as well and makes the code that uses them more
clear.

In both cases, the patches are _designed_ to fail to attract any
attention. Your earlier one had this preamble:
Here is a patch. I still feel a little silly writing this. The chances
that you will run out of memory doing setenv but _not_ doing any of the
other git operations seems very low.
which rather *loudly* says "ignore me, please!" ;-)
Erik's patch this round is no better; if its log message said something
like "On platform X, the environment space is merely nKB and setenv has
much higher chance of failing than on typical Linux boxes", it would have
been a no brainer for me to respond with "makes perfect sense but don't we
also use putenv?" immediately.

We could. Running out of environment space is not the same as running
out of memory. For instance, Windows has a maximum environment size of
32 kB. Older Linux kernels maxed out at 128 kB.
So I think it's a good idea to at least try. The worst that can happen
is another, less descriptive error, no?

It could be because I treated this completely like a theoretical
patch; I haven't seen it actually happen.
But you are right, Windows 32 kB environment limit makes this much
more likely than your average Linux box. So perhaps I should add a
notice about that in the next round...

Three points.
- error() gives you a LF at the end, so you do not have to have your own.
- That "have_..._ions()" is too long and ugly.
- The only thing you care about this callsite is if you have enough
permission to execute the "cmd".
In fact, you should not unconditionally require read permissions here.
$ chmod a-r $(type --path git) && /bin/ls -l $(type --path git)
--wx--x--x 109 junio junio 5126580 Dec 13 09:47 /home/junio/git-active/bin/git
$ /home/junio/git-active/bin/git --version
git version 1.7.8.249.gb1b73
You may need read permission when the file is a script (i.e. not binary
executable).

When checking if you can run "foo/bar/baz", directories "foo/" and "foo/bar/"
do not have to be readable. They only have to have executable bit to allow
descending into them, and typically this is called "searchable" (see man chmod).
$ mkdir -p /var/tmp/a/b && cp $(type --path git) /var/tmp/a/b/git
$ chmod 111 /var/tmp/a /var/tmp/a/b
$ /var/tmp/a/b/git --version
git version 1.7.8.249.gb1b73
I'd suggest having two helper functions, instead of the single one with
overlong "have...ions" name.
- can_search_directory() checks with access(X_OK);
- can_execute_file() checks with access(X_OK|R_OK), even though R_OK is
not always needed.
Use the former here where you check the directory that contains the
command, and use the latter up above where you check the command that is
supposed to be executable, and also down below after you checked sb.buf is
a path to a file that may be the command that is supposed to be
executable.
Then patch 2/2 can extend can_execute() to enhance its support for scripts
by reading the hash-bang line and validating it, etc.

Even with a single alternate database, multiple references are
advertised with the same name ".have". But the tests never push from a
repository with more than one reference in its alternates (verified by
instrumenting code). That is why my changes didn't cause test failures.
When I, for example, change the setup function in t5519 to push *two*
references to alice-pub, then master works fine, my ref-api branch
fails, and my fixup patch fixes the failure.

In a few minutes I will post a series of patches that store extra_refs
in a linked list separate from the reference caches, and iterates over
them only from for_each_ref(). I could rebase my ref-api-D changes on
top of this patch series in such a way that the extra refs are kept in
non-hierarchical storage. But I leave for vacation on Thursday so it is
quite likely that I won't be able to get it finished before I return in
the new year.
An alternative is to use my one-patch fix on top of the ref-api-D
changes (plus another patch to beef up t5519). The fix is isolated and
I'm confident that it is safe (though I would inspect and test it better
before formally submitting it). The advantage is that is less work, so
it can be ready tomorrow instead of in two weeks. The disadvantage is
that there would be an interval of commits on the feature branch (from
the middle of the ref-api-D patch series until the fix) that are
non-functional, albeit in a way that the test suite doesn't detect.

That is perfectly fine. Have fun.
I wasn't expecting the entire series to be ready during this cycle
anyway, and was planning to queue the clean-up series, up to 16/51

Since each branch in the alternate repo results in an "extra_ref"
named ".have", pushing two of them results in two extra_refs with the
same name. This change to the test therefore makes sure that we can
handle extra_refs names that are not unique.

I'm not sure how well this change fits into the other things that the

* [PATCH 0/6] Handle extra_refs separately from ref_caches

To: Junio C Hamano

Johan Herland, Julian Phillips, Michael Haggerty
From: Michael Haggerty <mhagger@alum.mit.edu>
Extra refs don't have much to do with real references, and in fact
they have to be handled differently. For example, they do not support
flags, they might not have unique names (indeed, the names are rather
meaningless), and they are only ever iterated over, never looked up.
So seemingly innocent things that one might want to do with real
references, like check for conflicting duplicates, must not be done
for extra refs.
This patch series creates a new linked-list data structure for the
extra refs, separates iteration over the extra refs into a new
function, and changes a test to actually create multiple extra refs
with the same name.
This patch series applies on top of master. If this approach is
selected, then the ref-api-D series will have to be rebased on top of
it and touched up to avoid the problems that it has with duplicate
extra refs.
By the way, I have been carrying around the CC list of this email for
quite a while. If you are tired of being spammed with my patch
series, send me a private email and I will be happy to remove you from
future mailings.

According to Junio, the only reference iteration function that needs
to include the extra refs is for_each_ref(). So call
do_for_each_extra_ref() directly from there instead of from
do_for_each_ref().
