Even if no one decides to do the getenv hunting (I haven't decided yet
whether it's worth the trouble, though patches like the setup_path()
one that make string lifetimes clearer are valuable anyway), this
looks useful as a debugging tool when people on strange platforms
report problems. And unlike the trick I sent a while ago, it doesn't
involve recompiling git. So for what it's worth,

t5000 avoids that issue by comparing only the contents of a
subdirectory. The script could do with a little cleanup, in any case.
Moving ZIP testing into its own file, more explicit pax header file
handling, speaking file and directory names, and modern coding style
would all be nice. :)

* [PATCH] archive-tar: split long paths more carefully
From: René Scharfe @ 2013-01-05 22:49 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git
In-Reply-To: <7vwqw7mb09.fsf@alter.siamese.dyndns.org>
The name field of a tar header has a size of 100 characters. This limit
was extended long ago in a backward compatible way by providing the
additional prefix field, which can hold 155 additional characters. The
actual path is constructed at extraction time by concatenating the prefix
field, a slash and the name field.
get_path_prefix() is used to determine which slash in the path is used as
the cutting point and thus which part of it is placed into the field
prefix and which into the field name. It tries to cram as much into the
prefix field as possible. (And only if we can't fit a path into the
provided 255 characters we use a pax extended header to store it.)
If a path is longer than 100 but shorter than 156 characters and ends
with a slash (i.e. is for a directory) then get_path_prefix() puts the
whole path in the prefix field and leaves the name field empty. GNU tar
reconstructs the path without complaint, but the tar included with
NetBSD 6 does not: It reports the header to be invalid.
For compatibility with this version of tar, make sure to never leave the
name field empty. In order to do that, trim the trailing slash from the
part considered as possible prefix, if it exists -- that way the last
path component (or more, but not less) will end up in the name field.

I did not read beyond the log message and the function signature of
the updated get_entry_index(), but it strikes me insane to build a
sorted list using case sensitive full string comarison and then to
look for an element in that list using a different comparison
criteria (e.g. case insensitive comparison) and to expect the
bisection search to still work. Shouldn't the codepath that builds
the string-list be sorting the list in case insensitive way from the
beginning if this were to work correctly?
It seems to suggest to me that this "are the keys case sensitive?"
bit belongs to the entire struct string_list structure as its
property (similar to the way "do the keys need to be strdup'ed?"
bit), not something you would flip per invocation basis of the
lookup function.
Also isn't size_t an unsigned type? What does it even mean to pass
"-1" to it, and propagate it down to strncmp()?
If you have a list sorted by a key, and if you want to query it with
a partial prefix of a possibly valid key, I think you shouldn't have
to add the "length search" at all. The existing look up function
would return the location in the list that short key would have been
inserted, which would come before the first entry that your short
key is a prefix of, so the caller can iterate the list from there to
find all entries. In other words, if existing list has "aaa",
"bba", and "bbc", and you want to grab entries that begin with "bb",
you can ask for "bb" to the loop up function, which would say "the
key does not exist in the list, but it would be inserted before this
'bba' entry". Then you can discover that "bba" and "bbc" both
matches the shortened key you have, no?

t/test-terminal.perl imitates the same logic. It doesn't check for
anything other than whether the exit status is 0, but maybe it would
be worth squashing in the below as a futureproofing measure
nonetheless.
Aside from the launch_editor bugfix, the only observable effects of
the above patch I can find are some changed error messages:
error: external filter cat failed -126
-> error: external filter cat failed 130
warning: svnrdump, returned -126
-> warning: svnrdump, returned 130
Those messages are equally senseless before and after the patch, so
for what it's worth,

Thanks for this.
I begin to suspect that this is the reason why path completion has not

These issues seems hard to fix.

Currently you can use mailmap to display log authors and committers
but you can't use the mailmap to find commits with mapped values.
This commit allows you to run:
git log --use-mailmap --author mapped_name_or_email
git log --use-mailmap --committer mapped_name_or_email
Of course it only works if the --use-mailmap option is used.
The new name and email are copied only when necessary.

The "--no-use-mailmap" option from the command line can countermand

The new option '--use-mailmap' can be used to make
sure that mailmap file is used to convert name
when running log commands.
The test is simple and checks that the Author line
is correctly replaced when running log.

* [PATCH 04/10] mailmap: simplify map_user() interface
From: Antoine Pelisse @ 2013-01-05 21:26 UTC (permalink / raw)
To: Junio C Hamano; +Cc: Antoine Pelisse, git
In-Reply-To: <1357421206-5014-1-git-send-email-apelisse@gmail.com>
The new string_list_lookup_extended() allows us to simplify map_user(),
mostly to avoid copies of string buffers. It also simplifies caller
functions.
map_user() directly receive pointers and length from the commit buffer
as mail and name. If mapping of the user and mail can be done, the
pointer is updated to a new location. Lengths are also updated if
necessary.
The caller of map_user() can then copy the new email and name if
necessary.

* [PATCH 03/10] mailmap: remove email copy and length limitation
From: Antoine Pelisse @ 2013-01-05 21:26 UTC (permalink / raw)
To: Junio C Hamano; +Cc: Antoine Pelisse, git
In-Reply-To: <1357421206-5014-1-git-send-email-apelisse@gmail.com>
In map_user(), the new string_list_lookup_extended() allows us to remove
the copy of email buffer to lower it.
This also removes the limitation on the length of the copy buffer and
simplifies the function.

Currently blame.c::get_acline, pretty.c::pp_user_info() and
shortlog.c::insert_one_record are parsing author name, email, time and
tz themselves.
Use ident.c::split_ident_line for better code reuse.

* [PATCH 01/10] list_lookup: create case and length search
From: Antoine Pelisse @ 2013-01-05 21:26 UTC (permalink / raw)
To: Junio C Hamano; +Cc: Antoine Pelisse, git
In-Reply-To: <1357421206-5014-1-git-send-email-apelisse@gmail.com>
Create a new function to look-up a string in a string_list, but:
- add a new parameter to ignore case differences
- add a length parameter to search for a substring
The idea is to avoid several copies (lowering a string before searching
it when we just want to ignore case), or copying a substring of a bigger
string to search it in the string_list

* [PATCH 00/10] Log mailmap optimization
From: Antoine Pelisse @ 2013-01-05 21:26 UTC (permalink / raw)
To: Junio C Hamano; +Cc: Antoine Pelisse, git
Hi,
Here is a reroll of ap/log-mailmap.
The idea is to use another preparatory step:
Allow case-insensitive and length search in list_lookup
We can now search for mapping name and email without any copy.
Of course a copy is then necessary to store the info, but we no
longer need any copy to look-up the mapping (useful for replacing or not
before grep).
Thanks,
Antoine Pelisse (10):
list_lookup: create case and length search
Use split_ident_line to parse author and committer
mailmap: remove email copy and length limitation
mailmap: simplify map_user() interface
mailmap: add mailmap structure to rev_info and pp
pretty: use mailmap to display username and email
log: add --use-mailmap option
test: add test for --use-mailmap option
log: grep author/committer using mailmap
log: add log.mailmap configuration option

That is confusing. I'll make it this:
git init depot
cd depot
git config git-p4.branchList main:branch1
git p4 clone --detect-branches //depot@all .

This feels like a bug to me, and indeed I had an old patch series
that planned to fix it. Let me knock that into shape, instead of
changing the documentation. It will automatically do the
checkout step you did.

Yes, also annoying. I have a failing test case for this, but
haven't fixed it yet. The idea is that "git p4 sync --branch=proj2"
will sync refs/remotes/p4/proj2. If there is no p4/master, and
you don't specify --branch, it will fail with a more useful error
message.
For submit, there is code that walks from your current branch
back in history until it finds a commit on a known p4 remote
branch. This is sort of like the merge-base calculation in git,
but restricted to a linear history. I haven't tested that
recently, but will add a test and fix it if needed too.
Please do feel welcome to to rearrange or expand the
documentation so it makes more sense, if you are so inspired.

* [Feature request] make git buildable from a separate directory
From: Manlio Perillo @ 2013-01-05 20:52 UTC (permalink / raw)

Hi.
Many C projects I have seen (based on autoconf, but not always - like
Nginx) allow the project to be build in a separate directory, in order
to avoid to pollute the working directory with compiled files.
Unfortunately this seems to not be possible with Git.
The Makefile seems quite complex to me, so I'm not sure to be able to
change it to do what I want, without breaking it.
Thanks Manlio

* [PATCH] status: report ignored yet tracked directories
From: Antoine Pelisse @ 2013-01-05 20:42 UTC (permalink / raw)
To: tboegi, peff; +Cc: git, Antoine Pelisse
In-Reply-To: <20130105112432.GA14666@sigill.intra.peff.net>
Tracked directories (i.e. directories containing tracked files) that
are ignored must be reported as ignored if they contain untracked files.
Currently, tracked files or directories can't be reported untracked or ignored.
Remove that constraint when searching ignored files.

Torsten, Jeff,
Can you please test this patch and tell me if this is better ? (t7061 is now
successful with core.ignorecase=true)
This patch applies on top of ap/status-ignored-in-ignored-directory (but
should also apply cleanly on top of next for testing purpose).
Thanks,

Thanks for this, it improves the situation dramatically.
I did further testing with your patch and found some less obvious
issues. I didn't debug the script myself as I'm not that familiar with
it either, but I think the testcases below should help Manlio or
someone else look into some regressions.
1- Using .. or . breaks completion when after the '/':
> cd git/contrib
> git rm ../contrib/completion/<tab>
../contrib/completion/ion.bash ../contrib/completion/ion.tcsh ../contrib/completion/ion.zsh ../contrib/completion/sh
It looks like the space taken by the path where we are located, eats up the same number of characters from the file name, e.g.,
../contrib/completion/ion.bash
../contrib/git-completion.bash
2- Maybe related to problem 1. Using .. breaks completion in other ways:
> cd git/contrib
> git rm ../con<tab>
../config.c ../config.mak.in ../configure.ac ../connect.c ../connected.c ../connected.h ../convert.c ../convert.h
Notice that 'contrib' is not proposed.
Don't be fooled by the fact that
> git rm ../cont<tab>
will complete to
> git rm ../contrib
as it is only because the completion script returned nothing, and bash file-completion
kicked-in instead (it fooled me :)).
3- Also probably related to problems 1 and 2. Using absolute paths behaves wierdly and
worse than before:
git rm /home/marc/git/git/con<tab>
will give
git rm /home/marc/git/git/config-
although there is the 'contrib' dir that should be shown, amongst others.
Seems like the same problem as above with 'git rm ../con<tab>'
In my opinion, the above three cases are regressions.
4- Completion choices include their entire path, which is not what bash does by default. For example:
> cd git/contrib
> ls completion/git-<tab>
git-completion.bash git-completion.tcsh git-completion.zsh git-prompt.sh
but
> git rm completion/git-<tab>
completion/git-completion.bash completion/git-completion.tcsh completion/git-completion.zsh completion/git-prompt.sh
notice the extra 'completion/' before each completion. This can get pretty large when completing with
many directory prefixes. The current tcsh completion has the same problem which I couldn't fix. However, I am
not sure if it can be fixed for bash.
I personally don't think this is regression, just an slight annoyance.
5- With this feature git-completion.bash will return directories as completions. This is something
git-completion.tcsh is not handling very well. I will post a patch to fix that.
Below are two suggestions that are in line with this effort but that are not regressions.
A) It would be nice if
git commit -a <TAB>
also completed with untracked files
B) Now that, for example, 'git rm' completion is smart about path completion
it would be nice to somehow not trigger bash default file completion
when 'git rm' does not report any completions.
For example, if I have a file called zz.tar.gz (which is an ignored file)
and I do 'git rm <tab>', I will get the proper list of files that can be
removed by git, excluding zz.tar.gz. But if I complete
'git rm zz.tar.<tab>' then the completion script will return nothing,
since git cannot remove that ignored file, but we will then fall-back
to the bash default completion, which will complete the file to zz.tar.gz.
Although there are some issues, I think this feature will greatly benefit the user
and is worth the time needed to fix.
Thanks!
Marc

* [PATCH] clone: support atomic operation with --separate-git-dir
From: Jens Lehmann @ 2013-01-05 20:17 UTC (permalink / raw)
To: Junio C Hamano
Cc: Heiko Voigt, git, Manlio Perillo, W. Trevor King,
Nguyen Thai Ngoc Duy
In-Reply-To: <50E83DAE.1080500@web.de>
Since b57fb80a7d (init, clone: support --separate-git-dir for .git file)
git clone supports the --separate-git-dir option to create the git dir
outside the work tree. But when that option is used, the git dir won't be
deleted in case the clone fails like it would be without this option. This
makes clone lose its atomicity as in case of a failure a partly set up git
dir is left behind. A real world example where this leads to problems is
when "git submodule update" fails to clone a submodule and later calls to
"git submodule update" stumble over the partially set up git dir and try
to revive the submodule from there, which then fails with a not very user
friendly error message.
Fix that by updating the junk_git_dir variable (used to remember if and
what git dir should be removed in case of failure) to the new value given
with the --seperate-git-dir option. Also add a test for this to t5600 (and
while at it fix the former last test to not cd into a directory to test
for its existence but use "test -d" instead).

And this fixes it for me. Manlio, it'd be great if you could test
this patch (but please not only remove .git/modules/<name> but also
the submodule work tree before doing that).

Hmph, I am reasonably sure I saw a test that created an archive from
a commit (hence with pax header), asked platform tar to either list
the contents or actually extracted to the filesystem, and tried to
ensure nothing but the paths in the repository existed in the
archive. When the platform tar implementation treated the pax
header as an extra file, such a test sees something not in the
repository and fails.
This was on (and I am still on) NetBSD 6.0 not 6.0.1, by the way.
