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

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

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.

085479e700 cygwin: trust executable bit by default
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.

Noticed by J6t, confirmed by Ramsay Jones, and the brown paper bag is on
Gitster's head.

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.

df599e9612 Windows: teach getenv to do a case-sensitive search
getenv() on Windows looks up environment variables in a case-insensitive
manner. Even though all documentations claim that the environment is
case-insensitive, it is possible for applications to pass an environment
to child processes that has variables that differ only in case. Bash on
Windows does this, for example, and sh-i18n--envsubst depends on this
behavior.

With this patch environment variables are first looked up in a
case-sensitive manner; only if this finds nothing, the system's getenv() is
used as a fallback.

06bc4b796a mingw.c: move definition of mingw_getenv down
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
of all call sites is changed.

a02cf90144 compat/fnmatch/fnmatch.c: give a fall-back definition for NULL
Somebody tried to compile fnmatch.c compatibility file on Interix and got
an error because no header included in the file on that platform defined
NULL.  It usually comes from stddef.h and indirectly from other headers
like string.h, unistd.h, stdio.h, stdlib.h, etc., but with the way we
compile this file from our Makefile, inclusion of the header files that
are expected to define NULL in fnmatch.c do not happen because they are
protected with "#ifdef STDC_HEADERS", etc. which we do not pass.

As the least-impact workaround, give a fall-back definition when none of

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.

d1b6e6e015 win32: use our own dirent.h
The mingw-runtime implemenation of opendir, readdir and closedir
sets errno to 0 on success, something that POSIX explicitly
forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be
read due to EMFILE") introduce a dependency on this behaviour,
leading to a broken "git clone" on Windows.

compat/mingw.c contains an implementation of readdir, and
compat/msvc.c contains implementations of opendir and closedir.

Move these to compat/win32/dirent.[ch], and change to our own DIR
structure at the same time.

This provides a generic Win32-implementation of opendir, readdir
and closedir which works on both MinGW and MSVC and does not reset
errno, and as a result git clone is working again on Windows.

52de4db579 mingw: use real pid
The Windows port have so far been using process handles in place
of PID. However, this is not work consistent with what getpid
returns.

PIDs are system-global identifiers, but process handles are local
to a process. Using PIDs instead of process handles allows, for
instance, a user to kill a hung process with the Task Manager,
something that would have been impossible with process handles.

Change the code to use the real PID, and use OpenProcess to get a
process-handle. Store the PID and the process handle in a linked
list protected by a critical section, so we can safely close the
process handle later.

Linked list code written by Pat Thoyts.

Syslog does not usually exist on Windows, so implement our own using
Window's ReportEvent mechanism.

Strings containing "%1" gets expanded into them selves by ReportEvent,
resulting in an unreadable string. "%2" and above is not a problem.
Unfortunately, on Windows an IPv6 address can contain "%1", so expand
"%1" to "% 1" before reporting. "%%1" is also a problem for ReportEvent,

9b9784cab9 MinGW: fix stat() and lstat() implementations for handling symlinks
In msysGit the stat() function has been implemented using mingw_lstat
which sets the st_mode member to S_IFLNK when a symbolic links is found.
This causes the is_executable function to return when git attempts to
build a list of available commands in the help code and we end up missing
most git commands. (msysGit issue #445)

This patch modifies the implementation so that lstat() will return the link
flag but if we are called as stat() we read the size of the target and set
the mode to that of a regular file.

Includes squashed fix st_mode for symlink dirs

ce518bbd6c Fix compat/regex ANSIfication on MinGW
compat/regexec.c had a weird combination of function declaration in ANSI
style and function definition in K&R style, for example:

 static unsigned
 re_copy_regs (struct re_registers *regs, regmatch_t *pmatch,
      int nregs, int regs_allocated) internal_function;

 static unsigned
 re_copy_regs (regs, pmatch, nregs, regs_allocated)
     struct re_registers *regs;
     regmatch_t *pmatch;
     int nregs, regs_allocated;
 { ... }

with this #define:

 #ifndef _LIBC
 # ifdef __i386__
 #  define internal_function   __attribute ((regparm (3), stdcall))
 # else
 #  define internal_function
 # endif
 #endif

The original version as shown above was fine, but with the ANSIfied
function definition and in the case where internal_function is not empty,
gcc identifies the declaration and definition as different and bails out.

Adding internal_function to the definition doesn't help (it results in
a syntax error); hence, remove it from the subset of declarations that gcc
flags as erroneous.

Bigger writes to network drives on Windows XP fail.  Cap them at 31MB to

that do less work than requested anyway.

On local drives, write() calls are translated to WriteFile() calls with
a cap of 64KB on Windows XP and 256KB on Vista.  Thus a cap of 31MB won't
affect the number of WriteFile() calls which do the actual work.  There's
still room for some other version of Windows to use a chunk size of 1MB
without increasing the number of system calls.

Since commit 0fcabdeb52, compat/bswap.h
redefined htonl and ntohl to bswap32 not only if bswap32 has been
defined earlier in compat/bswap.h (which is done only on selected
platforms), but also if bswap32 has been defined anywhere else.  This
broke Git at least for NetBSD systems running on big-endian machines
(where ntohl and htonl should, of course, be NOOPs), since NetBSD
defines a bswap32 macro in the system headers.

So, we now undefine any previously defined bswap32 in compat/bswap.h
before defining our own.

3fdcdbdf30 Windows: redirect f[re]open("/dev/null") to f[re]open("nul")
On Windows, the equivalent of "/dev/null" is "nul". This implements
compatibility wrappers around fopen() and freopen() that check for this
particular file name.

The new tests exercise code paths where this is relevant.

1f80c2afb0 Fix gitmkdtemp: correct test for mktemp() return value
In gitmkdtemp, the return value of mktemp is not tested correctly.
mktemp() always returns its 'template' argument, even upon failure.
An error is signalled by making the template an empty string.

947c3464e4 Implement pthread_cond_broadcast on Windows
See http://www.cse.wustl.edu/~schmidt/win32-cv-1.html, section "The
SignalObjectAndWait solution". But note that this implementation does not
use SignalObjectAndWait (which is needed to achieve fairness, but we do
not need fairness).

Note that our implementations of pthread_cond_broadcast and
pthread_cond_signal require that they are invoked with the mutex held that
is used in the pthread_cond_wait calls.

38743b7d10 msvc: Fix an "unrecognized option" linker warning
Having recently added support for building git-imap-send on
Windows, we now link against OpenSSL libraries, and the linker
issues the following warning:

    warning LNK4044: unrecognized option '/lssl'; ignored

In order to suppress the warning, we change the msvc linker
script to translate an '-lssl' parameter to the ssleay32.lib
library.

Note that the linker script was already including ssleay32.lib
(along with libeay32.lib) as part of the translation of the
'-lcrypto' library parameter.  However, libeay32.dll does not
depend on ssleay32.dll and can be used stand-alone, so we remove
ssleay32.lib from the '-lcrypto' translation.

The dependence of ssleay32.dll on libeay32.dll is represented in
the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable.

Also, add the corresponding change to the buildsystem generator.

a6d15bc335 Do not use date.c:tm_to_time_t() from compat/mingw.c
To implement gettimeofday(), a broken-down UTC time was requested from the
system using GetSystemTime(), then tm_to_time_t() was used to convert it
to a time_t because it does not look at the current timezone, which
mktime() would do.

Use GetSystemTimeAsFileTime() and a different conversion path to avoid this
back-reference from the compatibility layer to the generic code.

44626dc7d5 MSVC: Windows-native implementation for subset of Pthreads API
This patch implements native to Windows subset of pthreads API used by Git.
It allows to remove Pthreads for Win32 dependency for MSVC, msysgit and
Cygwin.

[J6t: If the MinGW build was built as part of the msysgit build
environment, then threading was already enabled because the
pthreads-win32 package is available in msysgit. With this patch, we can now
enable threaded code unconditionally.]

b6f714f89a MSVC: Fix an "incompatible pointer types" compiler warning
In particular, the following warning is issued while compiling
compat/msvc.c:

    ...mingw.c(223) : warning C4133: 'function' : incompatible \
types - from '_stati64 *' to '_stat64 *'

which relates to a call of _fstati64() in the mingw_fstat()
function definition.

This is caused by various layers of macro magic and attempts to
avoid macro redefinition compiler warnings. For example, the call
to _fstati64() mentioned above is actually a call to _fstat64(),
and expects a pointer to a struct _stat64 rather than the struct
_stati64 which is passed to mingw_fstat().

The definition of struct _stati64 given in compat/msvc.h had the
same "shape" as the definition of struct _stat64, so the call to
_fstat64() does not actually cause any runtime errors, but the
structure types are indeed incompatible.

In order to avoid the compiler warning, we add declarations for the
mingw_lstat() and mingw_fstat() functions and supporting macros to
msvc.h, suppressing the corresponding declarations in mingw.h, so
that we can use the appropriate structure type (and function) names
from the msvc headers.

75301f9015 Windows: avoid the "dup dance" when spawning a child process
When stdin, stdout, or stderr must be redirected for a child process that
on Windows is spawned using one of the spawn() functions of Microsoft's
C runtime, then there is no choice other than to

1. make a backup copy of fd 0,1,2 with dup
2. dup2 the redirection source fd into 0,1,2
3. spawn
4. dup2 the backup back into 0,1,2
5. close the backup copy and the redirection source

We used this idiom as well -- but we are not using the spawn() functions
anymore!

Instead, we have our own implementation. We had hardcoded that stdin,
stdout, and stderr of the child process were inherited from the parent's
fds 0, 1, and 2. But we can actually specify any fd.

With this patch, the fds to inherit are passed from start_command()'s
WIN32 section to our spawn implementation. This way, we can avoid the
backup copies of the fds.

The backup copies were a bug waiting to surface: The OS handles underlying
the dup()ed fds were inherited by the child process (but were not
associated with a file descriptor in the child). Consequently, the file or
pipe represented by the OS handle remained open even after the backup copy
was closed in the parent process until the child exited.

Since our implementation of pipe() creates non-inheritable OS handles, we
still dup() file descriptors in start_command() because dup() happens to
create inheritable duplicates. (A nice side effect is that the fd cleanup
in start_command is the same for Windows and Unix and remains unchanged.)
