make git-shell paranoid about closed stdin/stdout/stderr

It is in general unsafe to start a program with one or more of file
descriptors 0/1/2 closed.  Karl Chen for example noticed that stat_command
does this in order to rename a pipe file descriptor to 0:

    dup2(from, 0);
    close(from);

... but if stdin was closed (for example) from == 0, so that

    dup2(0, 0);
    close(0);

just ends up closing the pipe.  Another extremely rare but nasty problem
would occur if an "important" file ends up in file descriptor 2, and is
corrupted by a call to die().

Fixing this in git was considered to be overkill, so this patch works
around it only for git-shell.  The fix is simply to open all the "low"

Linus Torvalds [Thu, 28 Aug 2008 23:19:08 +0000 (16:19 -0700)]
Fix '--dirstat' with cross-directory renaming

The dirstat code depends on the fact that we always generate diffs with
the names sorted, since it then just does a single-pass walk-over of the
sorted list of names and how many changes there were. The sorting means
that all files are nicely grouped by directory.

That all works fine.

Except when we have rename detection, and suddenly the nicely sorted list
of pathnames isn't all that sorted at all. And now the single-pass dirstat
walk gets all confused, and you can get results like this:

  [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5
     3.0% arch/powerpc/configs/
     6.8% arch/arm/configs/
     2.7% arch/powerpc/configs/
     4.2% arch/arm/configs/
     5.6% arch/powerpc/configs/

     4.0% arch/
     4.4% drivers/usb/musb/
     4.0% drivers/watchdog/
     7.6% drivers/
     3.5% fs/

The trivial fix is to add a sorting pass, fixing it to:

  [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5
    43.0% arch/arm/configs/

     4.4% drivers/usb/musb/
     4.0% drivers/watchdog/
     7.6% drivers/
     3.5% fs/

Spot the difference. In case anybody wonders: it's because of a ton of
renames from {include/asm-blackfin => arch/blackfin/include/asm} that just
totally messed up the file ordering in between arch/arm and arch/powerpc.

it the other way around works, since "-i" just impacts the

Instead, we now always initialize the grep_filter member and
just fill in options and patterns as we get them. This means

merge: fix numerus bugs around "trivial merge" area

The "trivial merge" codepath wants to optimize itself by making an
internal call to the read-tree machinery, but it does not read the index
before doing so, and the codepath is never exercised.  Incidentally, this
failure to read the index upfront means that the safety to refuse doing
anything when the index is unmerged does not kick in, either.

These two problem are fixed by using read_cache_unmerged() that does read
the index before checking if it is unmerged at the beginning of
cmd_merge().

The primary logic of the merge, however, assumes that the process never
reads the index in-core, and the call to write_cache_as_tree() it makes
from write_tree_trivial() will always read from the on-disk index that is
prepared the strategy back-ends.  This assumption is now broken by the
above fix.  To fix this issue, we now call discard_cache() before calling
write_tree_trivial() when it wants to write the on-disk index as a tree.

When multiple strategies are tried, their results are evaluated by reading
the resulting index and inspecting it.  The codepath needs to make a call
to read_cache() for each successful strategy, and for that to work, they
need to discard_cache() the one read by the previous round.

Also the "trivial merge" forgot that the current commit is one of the
parents of the resulting commit.

unpack_trees(): protect the handcrafted in-core index from read_cache()

unpack_trees() rebuilds the in-core index from scratch by allocating a new
structure and finishing it off by copying the built one to the final
index.

The resulting in-core index is Ok for most use, but read_cache() does not
recognize it as such.  The function is meant to be no-op if you already
have loaded the index, until you call discard_cache().

This change the way read_cache() detects an already initialized in-core
index, by introducing an extra bit, and marks the handcrafted in-core
index as initialized, to avoid this problem.

A better fix in the longer term would be to change the read_cache() API so
that it will always discard and re-read from the on-disk index to avoid
confusion.  But there are higher level API that have relied on the current
semantics, and they and their users all need to get converted, which is
outside the scope of 'maint' track.

An example of such a higher level API is write_cache_as_tree(), which is
used by git-write-tree as well as later Porcelains like git-merge, revert
and cherry-pick.  In the longer term, we should remove read_cache() from
there and add one to cmd_write_tree(); other callers expect that the
in-core index they prepared is what gets written as a tree so no other
change is necessary for this particular codepath.

The original version of this patch marked the index by pointing an
otherwise wasted malloc'ed memory with o->result.alloc, but this version
uses Linus's idea to use a new "initialized" bit, which is conceptually
much cleaner.

git-submodule.sh - Remove trailing / from URL if found

git clone does not complain if a trailing '/' is included in the origin
URL, but doing so causes resolution of a submodule's URL relative to the
superproject to fail. Trailing /'s are likely when cloning locally using
tab-completion, so the slash may appear in either superproject or
submodule URL. So, ignore the trailing slash if it already exists in
the superproject's URL, and don't record one for the submodule (which
could itself have submodules...).

The problem I'm trying to fix is that a number of folks have
superprojects checked out where the recorded origin URL has a trailing
/, and a submodule has its origin in a directory sitting right next to
the superproject on the server. Thus, we have:

superproject url = server:/public/super
submodoule url = server:/public/sub1

However, in the checked out superproject's .git/config

[remote "origin"]
url = server:/public/super/

and for similar reasons, the submodule has its URL recorded in .gitmodules as
[submodule "sub"]

path = submodule1
url = ../sub1/

resolve_relative_url gets the submodule's recorded url as $1, which
the caller retrieved from .gitmodules, and retrieves the superprojects
origin from .git/config. So in this case resolve_relative_url has
that:

url = ../sub1/
remoteurl = server:/public/super/

So, without any patch, resolve_relative_url computes the submodule's URL as:

server:/public/super/sub1/

rather than

server:/public/sub1

In summary, it is essential that resolve_relative_url strip the
trailing / from the superproject's url before starting, and
beneficial if it assures that the result does not contain
a trailing / as the submodule may itself also be a superproject.

compat/snprintf.c: handle snprintf's that always return the # chars transmitted

Some platforms provide a horribly broken snprintf. More broken than the
platforms that return -1 when there is too little space in the target buffer
for the formatted string. Some platforms provide an snprintf which _always_
returns the number of characters transmitted to the buffer, regardless of
whether there was enough space or not.

IRIX 6.5 is such a platform. IRIX does have a working snprintf(), but it
is only provided when _NO_XOPEN5 evaluates to zero, and this only happens
if _XOPEN_SOURCE is defined, but definition of _XOPEN_SOURCE prevents
inclusion of many other common functions and defines. So it must be avoided.

Work around these horribly broken snprintf implementations by detecting an
snprintf call which results in the number of transmitted characters exactly
equal to the length of our buffer and retrying with a larger buffer just to
be safe.

git-svn: fix dcommit to urls with embedded usernames

Don't rely on the extracted URL from working_head_info since that has the
username removed.  Instead use the $gs->full_url method (as before with
ba24e74 (git-svn: add ability to specify --commit-url for dcommit,
2008-08-07)) to give us the URL to commit to if --commit-url is not
specified.

Aditionally, since we clean usernames from URLs, checking the URL after
rebase can fail because it doesn't match the URL we used to commit; so
unconditionally provide a username-free URL for checking the result of the
