When COLUMNS or --stat-width restricts the diff-stat width to near the
minimum, 26 columns, the graph_width value becomes negative. Consequently, the

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.

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.

Instead of waiting until we record the parents of resulting merge, reduce
redundant parents (including our HEAD) immediately after reading them.
The change to t7602 illustrates the essence of the effect of this change.
The octopus merge strategy used to be fed with redundant commits only to
discard them as "up-to-date", but we no longer feed such redundant commits
to it and the affected test degenerates to a regular two-head merge.
And obviously the known-to-be-broken test in t6028 is now fixed.

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.

If the branch configured as upstream didn't have a local tracking
branch, git said "Upstream branch not found". We can be more helpful,
and separate the cases when upstream is not configured, and when it is
configured, but the upstream branch is not tracked in a local branch.
The following configuration leads to the second scenario:
[remote "origin"]
url = ...
fetch = refs/heads/master
[branch "master"]
remote = origin
merge = refs/heads/master
'git pull' will work on master, but master@{upstream} is not defined.

When using @{u} or @{upstream} it is common to omit the branch name,
implying current branch. If the upstream is not configured, the error
message was "No upstream branch found for ''".
When resolving '@{u}', branch_get() is called, which almost always
returns a description of a branch. This allows us to use a branch name
in the error message, even if the user said something like '@{u}'.
The only case when branch_get() returns NULL is when HEAD points to so
something which is not a branch. Of course this also means that no
upstream is configured, but it is better to directly say that HEAD
does not point to a branch.

In preparation for future changes, add tests which show error messages
with @{upstream} in various conditions:
- test branch@{u} with . as remote
- check error message for branch@{u} on a branch with
* no upstream,
* on a branch with a configured upstream which doesn't have a
remote-tracking branch
- check error message for branch@{u} when branch 'branch' does not
exist
- check error message for @{u} without the branch name
Right now the messages are very similar, but various cases can and
will be distinguished.
Note: test_i18ncmp is not used, because currently error output is not
internationalized. test_cmp will be switched to test_i18ncmp in a later

Various failure modes in the repository detection code path currently
quote the wrong directory in their error message. The working directory
is changed iteratively to the parent directory until a git repository is
found. If the working directory cannot be changed to the parent
directory for some reason, the detection gives up and prints an error
message. The error message should report the current working directory.
Instead of continually updating the 'cwd' variable, which is actually
used to remember the original working directory, the 'offset' variable
is used to keep track of the current working directory. At the point
where the affected error handling code is called, 'offset' already
points to the end of the parent of the working directory, rather than
the current working directory.
Fix this by explicitly using a variable 'offset_parent' and update
'offset' concurrently with the call to chdir.
In a similar fashion, the function get_device_or_die() would print the
original working directory in case of a failure, rather than the current
working directory. Fix this as well by making use of the 'offset'
variable.
Lastly, replace the phrase 'mount parent' with 'mount point'. The former
appears to be a typo.

If fast-import's command pipe and the frontend's cat-blob/ls response
pipe are both filled, there can be a deadlock. Luckily all existing
frontends consume any pending cat-blob/ls responses completely before
writing the next command.
Document the requirements so future frontend authors and users can be
spared from the problem, too. It is not always easy to catch that
kind of bug by testing.
To set the scene, add some words of explanation to help the novice
understand that "cat-blob" and "ls" output are meant for consumption
by the frontend.
