7348159380 Merge branch 'ef/mingw-rmdir'
MinGW has a workaround when rmdir unnecessarily fails to retry with
a prompt, but the logic was kicking in when the rmdir failed with
ENOTEMPTY, i.e. was expected to fail and there is no point retrying.

a83b2b578c mingw_rmdir: do not prompt for retry when non-empty
in ab1a11be ("mingw_rmdir: set errno=ENOTEMPTY when appropriate"),
a check was added to prevent us from retrying to delete a directory
that is both in use and non-empty.

However, this logic was slightly flawed; since we didn't return
immediately, we end up falling out of the retry-loop, but right into
the prompting-loop.

Fix this by setting errno, and guarding the prompting-loop with an
errno-check.

afb43561b8 mingw: reuse tty-version of git_terminal_prompt
The getpass-implementation we use on Windows isn't at all ideal;
it works in raw-mode (as opposed to cooked mode), and as a result
does not deal correcly with deletion, arrow-keys etc.

Instead, use cooked mode to read a line at the time, allowing the
C run-time to process the input properly.

Since we set files to be opened in binary-mode by default on
Windows, introduce a FORCE_TEXT macro that expands to the "t"
modifier that forces the terminal to be opened in text-mode so we
do not have to deal with CRLF issues.

380a4d927b Update cygwin.c for new mingw-64 win32 api headers
The cygwin project recently switched to a new implementation of the
windows api, now using header files from the mingw-64 project. These
new header files are incompatible with the way cygwin.c included the
old headers: cygwin.c can be compiled using the new or the older (mingw)
headers, but different files must be included in different order for each
to work. The new headers are in use only for the current release series
(based upon the v1.7.x dll version). The previous release series using
the v1.5 dll is kept available but unmaintained for use on older versions
of Windows. So, patch cygwin.c to use the new include ordering only if
the dll version is 1.7 or higher.

this check may hide real errors on systems that do not have the this odd

67ba123fd1 terminal: seek when switching between reading and writing
When a stdio stream is opened in update mode (e.g., "w+"),
the C standard forbids switching between reading or writing
without an intervening positioning function. Many
implementations are lenient about this, but Solaris libc
will flush the recently-read contents to the output buffer.
In this instance, that meant writing the non-echoed password
that the user just typed to the terminal.

Fix it by inserting a no-op fseek between the read and
write.

The opposite direction (writing followed by reading) is also
disallowed, but our intervening fflush is an acceptable
positioning function for that alternative.

b856ad623e Merge branch 'tb/sanitize-decomposed-utf-8-pathname'
Teaches git to normalize pathnames read from readdir(3) and all
arguments from the command line into precomposed UTF-8 (assuming
that they come as decomposed UTF-8) to work around issues on Mac OS.

I think there still are other places that need conversion
(e.g. paths that are read from stdin for some commands), but this
should be a good first step in the right direction.

  git on Mac OS and precomposed unicode
2012-07-13 15:37:51 -07:00
Torsten Bögershausen
76759c7dff git on Mac OS and precomposed unicode
Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA.  When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.

Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".

As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode.  Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode.  When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.

The unicode decomposition causes many problems:

- The names "git add" and other commands get from the end user may
  often be precomposed form (the decomposed form is not easily input
  from the keyboard), but when the commands read from the filesystem
  to see what it is going to update the index with already is on the
  filesystem, readdir() will give decomposed form, which is different.

- Similarly "git log", "git mv" and all other commands that need to
  compare pathnames found on the command line (often but not always
  precomposed form; a command line input resulting from globbing may
  be in decomposed) with pathnames found in the tree objects (should
  be precomposed form to be compatible with other systems and for
  consistency in general).

- The same for names stored in the index, which should be
  precomposed, that may need to be compared with the names read from
  readdir().

NFS mounted from Linux is fully transparent and does not suffer from
the above.

As Mac OS X treats precomposed and decomposed file names as equal,
we can

 - wrap readdir() on Mac OS X to return the precomposed form, and

 - normalize decomposed form given from the command line also to the
   precomposed form,

to ensure that all pathnames used in Git are always in the
precomposed form.  This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.

The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv().  The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.

The argv[] conversion allows to use the TAB filename completion done
by the shell on command line.  It tolerates other tools which use
readdir() to feed decomposed file names into git.

When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".

The user needs to activate this feature manually.  She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

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.

1696d72321 compat/mingw.[ch]: Change return type of exec functions to int
The POSIX standard specifies a return type of int for all six exec
functions. In addition, all exec functions return -1 on error, and
simply do not return on success. However, the current emulation of
the exec functions on mingw are declared with a void return type.

This would cause a problem should any code attempt to call the
exec function in a non-void context. In particular, if an exec
function were used in a conditional it would fail to compile.

In order to improve the fidelity of the emulation, we change the
return type of the mingw_execv[p] functions to int and return -1
on error.

21aeafceda add generic terminal prompt function
When we need to prompt the user for input interactively, we
want to access their terminal directly. We can't rely on
stdio because it may be connected to pipes or files, rather
than the terminal. Instead, we use "getpass()", because it
abstracts the idea of prompting and reading from the
terminal.  However, it has some problems:

  1. It never echoes the typed characters, which makes it OK
     for passwords but annoying for other input (like usernames).

  2. Some implementations of getpass() have an extremely
     small input buffer (e.g., Solaris 8 is reported to
     support only 8 characters).

  3. Some implementations of getpass() will fall back to
     reading from stdin (e.g., glibc). We explicitly don't
     want this, because our stdin may be connected to a pipe
     speaking a particular protocol, and reading will
     disrupt the protocol flow (e.g., the remote-curl
     helper).

  4. Some implementations of getpass() turn off signals, so
     that hitting "^C" on the terminal does not break out of
     the password prompt. This can be a mild annoyance.

Instead, let's provide an abstract "git_terminal_prompt"
function that addresses these concerns. This patch includes
an implementation based on /dev/tty, enabled by setting
HAVE_DEV_TTY. The fallback is to use getpass() as before.

a9bfbc5b69 compat/snprintf: don't look at va_list twice
If you define SNPRINTF_RETURNS_BOGUS, we use a special
git_vsnprintf wrapper assumes that vsnprintf returns "-1"
instead of the number of characters that you would need to
store the result.

To do this, it invokes vsnprintf multiple times, growing a
heap buffer until we have enough space to hold the result.
However, this means we evaluate the va_list parameter
multiple times, which is generally a bad thing (it may be
modified by calls to vsnprintf, yielding undefined
behavior).

Instead, we must va_copy it and hand the copy to vsnprintf,
so we always have a pristine va_list.

040a655116 cleanup: use internal memory allocation wrapper functions everywhere
The "x"-prefixed versions of strdup, malloc, etc. will check whether the
allocation was successful and terminate the process otherwise.

A few uses of malloc were left alone since they already implemented a
graceful path of failure or were in a quasi external library like xdiff.

Additionally, the call to malloc in compat/win32/syslog.c was not modified
since the syslog() implemented there is a die handler and a call to the
x-wrappers within a die handler could result in recursion should memory
allocation fail.  This will have to be addressed separately.

Earlier 7974843 (compat/cygwin.c: make runtime detection of lstat/stat
lessor impact, 2008-10-23) fixed the low-level "do we use cygwin specific
hacks for stat/lstat?" logic not to call into git_default_config() from
random codepaths that are typically very late in the program, to prevent
the call from potentially overwriting other variables that are initialized
from the configuration.

However, it forgot that on Cygwin, trust-executable-bit should default to
true.

452993c297 t1301-*.sh: Fix the 'forced modes' test on cygwin
The 'forced modes' test fails on cygwin because the post-update
hook loses it's executable bit when copied from the templates
directory by git-init. The template loses it's executable bit
because the lstat() function resolves to the "native Win32 API"
implementation.

This call to lstat() happens after git-init has set the "git_dir"
(so has_git_dir() returns true), but before the configuration has
been fully initialised. At this point git_config() does not find
any config files to parse and returns 0. Unfortunately, the code
used to determine the cygwin l/stat() function bindings did not
check the return from git_config() and assumed that the config
was complete and accessible once "git_dir" was set.

In order to fix the test, we simply change the binding code to
test the return value from git_config(), to ensure that it actually
had config values to read, before determining the requested binding.

case-insensitive, it is possible for applications to pass an environment

Windows does this, for example, and sh-i18n--envsubst depends on this
behavior.

used as a fallback.

We want to use static lookup_env() in a subsequent change.

At first sight, this change looks innocent. But it is not due to the
#undef getenv. There is one caller of getenv between the old location and
the new location whose behavior could change. But as can be seen from the
defintion of mingw_getenv, the behavior for this caller does not change
substantially.

To ensure consistent behavior in the future, change all getenv callers
in mingw.c to use mingw_getenv.

With this patch, this is not a big deal, yet, but with the subsequent
change, where we teach getenv to do a case-sensitive lookup, the behavior

ab8632ae36 compat: provide a fallback va_copy definition
va_copy is C99.  We have avoided using va_copy many times in the past,
which has led to a bunch of cut-and-paste.  From everything I found
searching the web, implementations have historically either provided
va_copy or just let your code assume that simple assignment of worked.

So my guess is that this will be sufficient, though we won't really
know for sure until somebody reports a problem.

ab1a11be78 mingw_rmdir: set errno=ENOTEMPTY when appropriate
On Windows, EACCES overrules ENOTEMPTY when calling rmdir(). But if the
directory is busy, we only want to retry deleting the directory if it
is empty, so test specifically for that case and set ENOTEMPTY rather
than EACCES.

Noticed by Greg Hazel.

4f288100ce mingw: add fallback for rmdir in case directory is in use
The same logic as for unlink and rename also applies to rmdir. For
example in case you have a shell open in a git controlled folder. This
will easily fail. So lets be nice for such cases as well.

c9b7840080 mingw: make failures to unlink or move raise a question
On Windows in case a program is accessing a file unlink or
move operations may fail. To give the user a chance to correct
this we simply wait until the user asks us to retry or fail.

This is useful because of the following use case which seem
to happen rarely but when it does it is a mess:

After making some changes the user realizes that he was on the
incorrect branch. When trying to change the branch some file
is still in use by some other process and git stops in the
middle of changing branches. Now the user has lots of files
with changes mixed with his own. This is especially confusing
on repositories that contain lots of files.

Although the recent implementation of automatic retry makes
this scenario much more unlikely lets provide a fallback as
a last resort.

Thanks to Albert Dvornik for disabling the question if users can't see it.

If the stdout of the command is connected to a terminal but the stderr
has been redirected, the odds are good that the user can't see any
question we print out to stderr.  This will result in a "mysterious
hang" while the app is waiting for user input.

It seems better to be conservative, and avoid asking for input
whenever the stderr is not a terminal, just like we do for stdin.
