1900b976a4 read_loose_refs(): rename function from get_ref_dir()
The new name better describes the function's purpose, and also makes
the old name available for a more suitable purpose.

9f2fb4a373 get_ref_dir(): take the containing directory as argument
Previously, the "dir" argument to get_ref_dir() was a pointer to the
top-level ref_dir.  Change the function to expect a pointer to the
ref_dir corresponding to dirname.  This allows entries to be added
directly to dir, without having to recurse through the reference trie
each time (i.e., we can use add_entry_to_dir() instead of add_ref()).

6ade9bdada git-svn: ignore SIGPIPE
In HTTP with keep-alive it's not uncommon for the client to notice that
the server decided to stop maintaining the current connection only when
sending a new request.  This naturally results in -EPIPE and possibly
SIGPIPE.

The subversion library itself makes no provision for SIGPIPE.  Some
combinations of the underlying libraries do (typically SIG_IGN-ing it),
some don't.

Presumably for that reason all subversion commands set SIGPIPE to
SIG_IGN early in their main()-s.

So should we.

This, together with the previous patch, fixes the notorious "git-svn
died of signal 13" problem (see e.g.
http://thread.gmane.org/gmane.comp.version-control.git/134936).

037a98cd3f git-svn: use POSIX::sigprocmask to block signals
In order to maintain consistency of the database mapping svn revision
numbers to git commit ids, rev_map_set() defers signal processing until
it's finished with an append transaction.[*]

The conventional way to achieve this is through sigprocmask(), which is
available in perl in the standard POSIX module.

This is implemented by this patch.  One important consequence of it is
that the signal handlers won't be unconditionally set to SIG_DFL anymore
upon the first invocation of rev_map_set() as they used to.  As a
result, the signals ignored by git-svn parent will remain ignored;
otherwise the behavior remains the same.

This patch paves the way to ignoring SIGPIPE throughout git-svn which
will be done in the followup patch.

[*] Deferring signals is not enough to ensure the database consistency:
the program may die on SIGKILL or power loss, run out of disk space,
etc.  However that's a separate issue that this patch doesn't address.

64394e3ae9 git-submodule.sh: Don't use $path variable in eval_gettext string
The eval_gettext (and eval_gettextln) i18n shell functions call
git-sh-i18n--envsubst to process the variable references in the
string parameter. Unfortunately, environment variables are case
insensitive on windows, which leads to failure on cygwin when
eval_gettext exports $path.

Commit df599e9 (Windows: teach getenv to do a case-sensitive search,
06-06-2011) attempts to solve this problem on MinGW by overriding
the system getenv() function to allow git-sh-i18n--envsubst to read
$path rather than $PATH from the environment. However, this commit
does not address cygwin at all and, furthermore, does not fix all
problems on MinGW.

In particular, when executing test #38 in t7400-submodule-basic.sh,
an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog
pops up saying that the application "failed to start because
libiconv2.dll was not found." After studying the voluminous trace
output from the process monitor, it is clear that the system is
attempting to use $path, rather than $PATH, to search for the DLL
file. (Note that, after dismissing the dialog, the test passes
anyway!)

As an alternative, we finesse the problem by renaming the $path
variable to $sm_path (submodule path). This fixes the problem on
MinGW along with all test failures on cygwin (t7400.{7,32,34},
t7406.3 and t7407.{2,6}). We note that the foreach subcommand
provides $path to user scripts (ie it is part of the API), so we
can't simply rename it to $sm_path.

90110d7645 compat/mingw.h: Set S_ISUID to prevent a fast-import test failure
The current t9300-fast-import.sh test number 62 ("L: nested tree
copy does not corrupt deltas") was introduced in commit 9a0edb79
("fast-import: add a test for tree delta base corruption",
15-08-2011). A fix for the demonstrated problem was introduced
by commit 8fb3ad76 ("fast-import: prevent producing bad delta",
15-08-2011). However, this fix didn't work on MinGW and so this
test has always failed on MinGW.

Part of the solution in commit 8fb3ad76 was to add an NO_DELTA
preprocessor constant which was defined as follows:

  +/*
  + * We abuse the setuid bit on directories to mean "do not delta".
  + */
  +#define NO_DELTA S_ISUID
  +

Unfortunately, the S_ISUID constant on MinGW is defined as zero.

In order to fix the problem, we simply alter the definition of
S_ISUID in the mingw header file to a more appropriate value.
Also, we take the opportunity to similarly define S_ISGID and
S_ISVTX.

776297548e Do not use SHELL_PATH from build system in prepare_shell_cmd on Windows
The recent change to use SHELL_PATH instead of "sh" to spawn shell commands
is not suited for Windows:

- The default setting, "/bin/sh", does not work when git has to run the
  shell because it is a POSIX style path, but not a proper Windows style
  path.

- If it worked, it would hard-code a position in the files system where
  the shell is expected, making git (more precisely, the POSIX toolset that
  is needed alongside git) non-relocatable. But we cannot sacrifice
  relocatability on Windows.

- Apart from that, even though the Makefile leaves SHELL_PATH set to
  "/bin/sh" for the Windows builds, the build system passes a mangled path
  to the compiler, and something like "D:/Src/msysgit/bin/sh" is used,
  which is doubly bad because it points to where /bin/sh resolves to on
  the system where git was built.

- Finally, the system's CreateProcess() function that is used under
  mingw.c's hood does not work with forward slashes and cannot find the
  shell.

Undo the earlier change on Windows.
