When spawning child processes via start_command(), the environment and all
environment entries are copied twice. First by make_augmented_environ /
copy_environ to merge with child_process.env. Then a second time by
make_environment_block to create a sorted environment block string as
required by CreateProcess.
Move the merge logic to make_environment_block so that we only need to copy
the environment once. This changes semantics of the env parameter: it now
expects a delta (such as child_process.env) rather than a full environment.
This is not a problem as the parameter is only used by start_command()
(all other callers previously passed char **environ, and now pass NULL).
The merge logic no longer xstrdup()s the environment strings, so do_putenv
must not free them. Add a parameter to distinguish this from normal putenv.
Remove the now unused make_augmented_environ / free_environ API.

All functions that modify the environment have memory leaks.
Disable gitunsetenv in the Makefile and use env_setenv (via mingw_putenv)
instead (this frees removed environment entries).
Move xstrdup from env_setenv to make_augmented_environ, so that
mingw_putenv no longer copies the environment entries (according to POSIX
[1], "the string [...] shall become part of the environment"). This also
fixes the memory leak in gitsetenv, which expects a POSIX compliant putenv.
[1] http://pubs.opengroup.org/onlinepubs/009695399/functions/putenv.html
Note: This patch depends on taking control of char **environ and having
our own mingw_putenv (both introduced in "Win32: Unicode environment
(incoming)").

Convert environment from UTF-16 to UTF-8 on startup.
No changes to getenv() are necessary, as the MSVCRT version is implemented
on top of char **environ.
However, putenv / _wputenv from MSVCRT no longer work, for two reasons:
1. they try to keep environ, _wenviron and the Win32 process environment
in sync, using the default system encoding instead of UTF-8 to convert
between charsets
2. msysgit and MSVCRT use different allocators, memory allocated in git
cannot be freed by the CRT and vice versa
Implement mingw_putenv using the env_setenv helper function from the
environment merge code.
Note that in case of memory allocation failure, putenv now dies with error
message (due to xrealloc) instead of failing with ENOMEM. As git assumes
setenv / putenv to always succeed, this prevents it from continuing with
incorrect settings.

Replaces Windows "ANSI" APIs dealing with file- or path names with their
Unicode equivalent, adding UTF-8/UTF-16LE conversion as necessary.
The dirent API (opendir/readdir/closedir) is updated in a separate commit.
Adds trivial wrappers for access, chmod and chdir.
Adds wrapper for mktemp (needed for both mkstemp and mkdtemp).
The simplest way to convert a repository with legacy-encoded (e.g. Cp1252)
file names to UTF-8 ist to checkout with an old msysgit version and
"git add --all & git commit" with the new version.
Includes a fix for bug reported by John Chen:
On Windows XP (not Win7), directories cannot be deleted while a find handle
is open, causing "Deletion of directory '...' failed. Should I try again?"
prompts.
Prior to this commit, these failures were silently ignored due to
strbuf_free in is_dir_empty resetting GetLastError to ERROR_SUCCESS.
Close the find handle in is_dir_empty so that git doesn't block deletion
of the directory even after all other applications have released it.

As of "Win32: Thread-safe windows console output", git-log no longer
terminates when the pager process dies. This is due to disabling buffering
for the replaced stdout / stderr streams. Git-log will periodically fflush
stdout (see write_or_die.c/mayble_flush_or_die()), but with no buffering,
this is a NOP that always succeeds (so we never detect the EPIPE error).
Exchange the original console handles with our console thread pipe handles
by accessing the internal MSVCRT data structures directly (which are
exposed via __pioinfo for some reason).
Implement this with minimal assumptions about the actual data structure to
make it work with different (hopefully even future) MSVCRT versions.
While messing with internal data structures is ugly, this patch solves the
problem at the source instead of adding more workarounds. We no longer need
the special winansi_isatty override, and the limitations documented in
"Win32: Thread-safe windows console output" are gone (i.e. fdopen(1/2)
returns unbuffered streams now, and isatty() for duped console file
descriptors works as expected).

Winansi.c has many static variables that are accessed and modified from
the [v][f]printf / fputs functions overridden in the file. This may cause
multi threaded git commands that print to the console to produce corrupted
output or even crash.
Additionally, winansi.c doesn't override all functions that can be used to
print to the console (e.g. fwrite, write, fputc are missing), so that ANSI
escapes don't work properly for some git commands (e.g. git-grep).
Instead of doing ANSI emulation in just a few wrapped functions on top of
the IO API, let's plug into the IO system and take advantage of the thread
safety inherent to the IO system.
Redirect stdout and stderr to a pipe if they point to the console. A
background thread reads from the pipe, handles ANSI escape sequences and
UTF-8 to UTF-16 conversion, then writes to the console.
The pipe-based stdout and stderr replacements must be set to unbuffered, as
MSVCRT doesn't support line buffering and fully buffered streams are
inappropriate for console output.
Due to the byte-oriented pipe, ANSI escape sequences and multi-byte UTF-8
sequences can no longer be expected to arrive in one piece. Replace the
string-based ansi_emulate() with a simple stateful parser (this also fixes
colored diff hunk headers, which were broken as of commit 2efcc977).
Override isatty to return true for the pipes redirecting to the console.
Exec/spawn obtain the original console handle to pass to the next process
via winansi_get_osfhandle().
All other overrides are gone, the default stdio implementations work as
expected with the piped stdout/stderr descriptors.
Global variables are either initialized on startup (single threaded) or
exclusively modified by the background thread. Threads communicate through
the pipe, no further synchronization is necessary.
The background thread is terminated by disonnecting the pipe after flushing
the stdio and pipe buffers. This doesn't work for anonymous pipes (created
via CreatePipe), as DisconnectNamedPipe only works on the read end, which
discards remaining data. Thus we have to setup the pipe manually, with the
write end beeing the server (opened with CreateNamedPipe) and the read end
the client (opened with CreateFile).
Limitations: doesn't track reopened or duped file descriptors, i.e.:
- fdopen(1/2) returns fully buffered streams
- dup(1/2), dup2(1/2) returns normal pipe descriptors (i.e. isatty() =
false, winansi_get_osfhandle won't return the original console handle)
Currently, only the git-format-patch command uses xfdopen(xdup(1)) (see
"realstdout" in builtin/log.c), but works well with these limitations.

Add Unicode conversion functions to convert between Windows native UTF-16LE
encoding to UTF-8 and back.
To support repositories with legacy-encoded file names, the UTF-8 to UTF-16
conversion function tries to create valid, unique file names even for
invalid UTF-8 byte sequences, so that these repositories can be checked out
without error.
The current implementation leaves invalid UTF-8 bytes in range 0xa0 - 0xff
as is (producing printable Unicode chars \u00a0 - \u00ff, equivalent to
ISO-8859-1), and converts 0x80 - 0x9f to hex-code (\u0080 - \u009f are
control chars).
The Windows MultiByteToWideChar API was not used as it either drops invalid
UTF-8 sequences (on Win2k/XP; producing non-unique or even empty file
names) or converts them to the replacement char \ufffd (Vista/7; causing
ERROR_INVALID_NAME in subsequent calls to file system APIs).

In msvc.h, there's a couple of stat related functions defined diffently
from mingw.h. When we remove these definitions, the only problem we get is
"warning C4005: '_stati64' : macro redefinition" for this line in mingw.h:
#define _stati64(x,y) mingw_stat(x,y)
The reason is that as of MSVCR80.dll (distributed with MSVC 2005), the
original _stati64 family of functions was renamed to _stat32i64, and the
former function names became macros (pointing to the appropriate function
based on the definition of _USE_32BIT_TIME_T).
Defining _stati64 works on MinGW because MinGW by default compiles against
the MSVCRT.DLL that is part of Windows (i.e. _stati64 is a function rather
than a macro).
Note: MinGW *can* compile for newer MSVC runtime versions, and MSVC
apparently can also compile for the Windows MSVCRT.DLL via the DDK (see
http://www.syndicateofideas.com/posts/fighting-the-msvcrt-dll-hell ).
Remove the stat definitions from msvc.h, as they are not compiler related.
In mingw.h, determine the runtime version in use from the definitions of
_stati64 and _USE_32BIT_TIME_T, and define stat() accordingly.
This also fixes that stat() in MSVC builds still resolves to mingw_lstat()
instead of mingw_stat().

Sparse issues 68 errors (two errors for each main() function) such
as the following:
SP git.c
git.c:510:5: error: too many arguments for function mingw_main
git.c:510:5: error: symbol 'mingw_main' redeclared with different type \
(originally declared at git.c:510) - different argument counts
The errors are caused by the 'main' macro used by the MinGW build
to provide a replacement main() function. The original main function
is effectively renamed to 'mingw_main' and is called from the new
main function. The replacement main is used to execute certain actions
common to all git programs on MinGW (e.g. ensure the standard I/O
streams are in binary mode).
In order to suppress the errors, we change the macro to include the
parameters in the declaration of the mingw_main function.
Unfortunately, this change provokes both sparse and gcc to complain
about 9 calls to mingw_main(), such as the following:
CC git.o
git.c: In function 'main':
git.c:510: warning: passing argument 2 of 'mingw_main' from \
incompatible pointer type
git.c:510: note: expected 'const char **' but argument is of \
type 'char **'
In order to suppress these warnings, since both of the main
functions need to be declared with the same prototype, we
change the declaration of the 9 main functions, thus:
int main(int argc, char **argv)

compat/mingw.c:1207:23: warning: Using plain integer as NULL pointer
In 'pinfo_t' variable, defined on line 795, seems to have been a
mistake (a missing typedef keyword?), so we simply remove it.
The 'pinfo' variable does not require more than file scope, so we
simply add the static modifier to the declaration.
The 'pinfo_cs' variable, in contrast, requires initialisation in the
mingw replacement main() function, so we add an extern declaration to
the compat/mingw.h header file.
The remaining warning is suppressed by replacing the rhs of the
pointer assignment with the NULL pointer literal.

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.

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.

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.

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.
