We have a hack in the port tree, but I haven't\n yet taken the time to clean it up enough.\n\n- The test suite does not pass because of missing features like symbolic\n links. Again we have adjusted the tests in the port tree so that the\n test suite can be completed unattended.\n\n\nI've arranged the patches in a few subsets. They are different from what\nDscho had proposed some weeks ago when I announced the series for the\nfirst time because I felt this topical partitioning makes more sense.\n\n\n* Part 1: Get it going\n01/40 Add compat/regex.[ch] and compat/fnmatch.[ch].\n02/40 Compile some programs only conditionally.\n03/40 Add target architecture MinGW.\n\nWith these patches we have a working git.exe that can successfully run\nthose builtins that need only read-access of the repository, like\ngit log, git diff, etc.\n\n 7 files changed, 6222 insertions(+), 5 deletions(-)\n\n\n* Part 2: Working locally is possible\n04/40 Windows: Use the Windows style PATH separator ';'.\n05/40 Windows: Strip \".exe\" from the program name.\n06/40 Windows: Implement a wrapper of the open() function.\n07/40 Windows: A minimal implemention of getpwuid().\n08/40 Windows: always chmod(, 0666) before unlink().\n09/40 Windows: Work around misbehaved rename().\n10/40 Windows: Treat Windows style path names.\n11/40 Windows: Handle absolute paths in safe_create_leading_directories().\n12/40 Windows: Implement gettimeofday().\n13/40 Windows: Fix PRIuMAX definition.\n14/40 Windows: Implement setitimer() and sigaction().\n15/40 Windows: A work-around for a misbehaved vsnprintf.\n\nNow builtins that write to the repository work as long as they don't need\nto spawn secondary processes.\n\n 10 files changed, 347 insertions(+), 20 deletions(-)\n\n\n* Part 3: Shell scripts and start_command()\n16/40 Windows: Wrap execve so that shell scripts can be invoked.\n17/40 Windows: A pipe() replacement whose ends are not inherited to children.\n18/40 Windows: Implement start_command().\n19/40 Windows: Change the name of hook scripts to make them not executable.\n\nNow scripted tools and the builtins and standalone programs work that\ndepend on start_command().\n\n 5 files changed, 391 insertions(+), 16 deletions(-)\n\n\n* Part 4: Remote connections\n20/40 Windows: A rudimentary poll() emulation.\n21/40 Windows: Disambiguate DOS style paths from SSH URLs.\n22/40 Windows: Implement asynchronous functions as threads.\n23/40 Windows: Local clone must use the drive letter in absolute paths.\n24/40 Windows: Work around incompatible sort and find.\n25/40 Windows: Implement a cpio emulation in git-clone.sh.\n26/40 Windows: Implement wrappers for gethostbyname(), socket(), and connect().\n\nRemote connections, both push and fetch, using local transport as well as\nconnections via ssh and native git protocol work.\n\n 9 files changed, 233 insertions(+), 3 deletions(-)\n\n\n* Part 5: Optimizations\n27/40 Windows: Implement a custom spawnve().\n28/40 Windows: Add a new lstat and fstat implementation based on Win32 API.\n29/40 Windows: Use a customized struct stat that also has the st_blocks member.\n\n 3 files changed, 370 insertions(+), 10 deletions(-)\n\n\n* Part 6: Tie up loose ends\n30/40 Turn builtin_exec_path into a function.\n31/40 Compute the ultimate fallback for exec_path from the program invocation.\n32/40 Windows: Use a relative default template_dir and ETC_GITCONFIG\n33/40 When installing, be prepared that template_dir may be relative.\n34/40 Windows: Make the pager work.\n35/40 Windows: Work around an oddity when a pipe with no reader is written to.\n36/40 Avoid the \"dup dance\" in wt_status_print_verbose() when possible.\n37/40 Windows: Make 'git help -a' work.\n38/40 Windows: TMP and TEMP environment variables specify a temporary directory.\n39/40 Windows: Fix ntohl() related warnings about printf formatting\n40/40 compat/pread.c: Add foward decl to fix warning\n\nThis fixes some final remaining oddities, minor missing features, and\nworks around differences between POSIX and Windows.\n\n 11 files changed, 154 insertions(+), 21

Instead,\nwe must use this idiom:\n\n save1 = dup(1);\n pipe(fd);\n dup2(fd[1], 1);\n spawn(...);\n dup2(save1, 1);\n close(fd[1]);\n\ni.e. save away the descriptor at the destination slot, replace by the pipe\nend, spawn process, restore the saved file.\n\nBut there is a problem: Notice that the child did not only inherit the\ndup2()ed descriptor, but also *both* original pipe ends. Although the one\nend that was dup()ed could be closed before the spawn(), we cannot close\nthe other end - the child inherits it, no matter what.\n\nThe solution is to generate non-inheritable pipes. At the first glance,\nthis looks strange: The purpose of pipes is usually to be inherited to\nchild processes. But notice that in the course of actions as outlined\nabove, the pipe descriptor that we want to inherit to the child is\ndup2()ed, and as it so happens, Windows's dup2() creates inheritable\nduplicates.\n\nSigned-off-by: Johannes Sixt \n---\n compat/mingw.c | 45 +++++++++++++++++++++++++++++++++++++++++++++\n git-compat-util.h | 5 +----\n 2 files changed, 46 insertions(+), 4 deletions(-)\n\ndiff --git a/compat/mingw.c b/compat/mingw.c\nindex 9d03ea5..fe6f6ce 100644\n--- a/compat/mingw.c\n+++ b/compat/mingw.c\n@@ -55,6 +55,51 @@ int gettimeofday(struct timeval *tv, void *tz)\n \treturn 0;\n }\n \n+int pipe(int filedes[2])\n+{\n+\tint fd;\n+\tHANDLE h[2], parent;\n+\n+\tif (_pipe(filedes, 8192, 0) < 0)\n+\t\treturn -1;\n+\n+\tparent = GetCurrentProcess();\n+\n+\tif (!DuplicateHandle (parent, (HANDLE)_get_osfhandle(filedes[0]),\n+\t\t\tparent, &h[0], 0, FALSE, DUPLICATE_SAME_ACCESS)) {\n+\t\tclose(filedes[0]);\n+\t\tclose(filedes[1]);\n+\t\treturn -1;\n+\t}\n+\tif (!DuplicateHandle (parent, (HANDLE)_get_osfhandle(filedes[1]),\n+\t\t\tparent, &h[1], 0, FALSE, DUPLICATE_SAME_ACCESS)) {\n+\t\tclose(filedes[0]);\n+\t\tclose(filedes[1]);\n+\t\tCloseHandle(h[0]);\n+\t\treturn -1;\n+\t}\n+\tfd = _open_osfhandle((int)h[0], O_NOINHERIT);\n+\tif (fd < 0) {\n+\t\tclose(filedes[0]);\n+\t\tclose(filedes[1]);\n+\t\tCloseHandle(h[0]);\n+\t\tCloseHandle(h[1]);\n+\t\treturn -1;\n+\t}\n+\tclose(filedes[0]);\n+\tfiledes[0] = fd;\n+\tfd = _open_osfhandle((int)h[1], O_NOINHERIT);\n+\tif (fd < 0) {\n+\t\tclose(filedes[0]);\n+\t\tclose(filedes[1]);\n+\t\tCloseHandle(h[1]);\n+\t\treturn -1;\n+\t}\n+\tclose(filedes[1]);\n+\tfiledes[1] = fd;\n+\treturn 0;\n+}\n+\n int poll(struct pollfd *ufds, unsigned int nfds, int timeout)\n {\n \treturn 0;\ndiff --git a/git-compat-util.h b/git-compat-util.h\nindex e191a46..170c279 100644\n--- a/git-compat-util.h\n+++ b/git-compat-util.h\n@@ -571,14 +571,11 @@ static inline int waitpid(pid_t pid, unsigned *status, unsigned options)\n \treturn -1;\n }\n \n-\n-static inline int pipe(int filedes[2])\n-{ return _pipe(filedes, 8192, 0); }\n-\n /*\n * implementations of missing functions\n */\n \n+int pipe(int filedes[2]);\n unsigned int sleep (unsigned int seconds);\n int gettimeofday(struct timeval *tv, void *tz);\n int poll(struct pollfd *ufds, unsigned int nfds, int timeout);\n-- \n1.5.4.1.126.ge5a7d\n"},{"id":"70134","messageId":"1204138503-6126-19-git-send-email-johannes.sixt@telecom.at","threadId":"12344","inReplyTo":"1204138503-6126-1-git-send-email-johannes.sixt@telecom.at","subject":"[PATCH 18/40] Windows: Implement start_command().","fromName":"Johannes Sixt","fromEmail":"johannes.sixt@telecom.at","sentAt":"2008-02-27T18:54:41Z","receivedAt":"2008-02-27T18:54:41Z","isPatch":true,"sender":{"key":"j6t@kdbg.org","avatar":"https://avatars.githubusercontent.com/u/14810926?v=4"},"body":"On Windows, we have spawnv() variants to run a child process instead of\nfork()/exec().

Other channels (file handles, pipe handles,\netc.) are still inherited by the spawned program, but it doesn't get\nenough information to access them.\n\nJohannes Schindelin integrated path quoting and unified the various\n*execv* and *spawnv* helpers.\n\nSigned-off-by: Johannes Sixt \n---\n compat/mingw.c | 203 +++++++++++++++++++++++++++++++++++++++++++++++++++--\n git-compat-util.h | 1 +\n run-command.c | 2 +-\n 3 files changed, 199 insertions(+), 7 deletions(-)\n\ndiff --git a/compat/mingw.c b/compat/mingw.c\nindex 1260be8..146c170 100644\n--- a/compat/mingw.c\n+++ b/compat/mingw.c\n@@ -1,4 +1,5 @@\n #include \"../git-compat-util.h\"\n+#include \"../strbuf.h\"\n \n unsigned int _CRT_fmode = _O_BINARY;\n \n@@ -190,6 +191,65 @@ char *mingw_getcwd(char *pointer, int len)\n \treturn ret;\n }\n \n+/*\n+ * See http://msdn2.microsoft.com/en-us/library/17w5ykft(vs.71).aspx\n+ * (Parsing C++ Command-Line Arguments)\n+ */\n+static const char *quote_arg(const char *arg)\n+{\n+\t/* count chars to quote */\n+\tint len = 0, n = 0;\n+\tint force_quotes = 0;\n+\tchar *q, *d;\n+\tconst char *p = arg;\n+\tif (!*p) force_quotes = 1;\n+\twhile (*p) {\n+\t\tif (isspace(*p) || *p == '*' || *p == '?')\n+\t\t\tforce_quotes = 1;\n+\t\telse if (*p == '\"')\n+\t\t\tn++;\n+\t\telse if (*p == '\\\\') {\n+\t\t\tint count = 0;\n+\t\t\twhile (*p == '\\\\') {\n+\t\t\t\tcount++;\n+\t\t\t\tp++;\n+\t\t\t\tlen++;\n+\t\t\t}\n+\t\t\tif (*p == '\"')\n+\t\t\t\tn += count*2 + 1;\n+\t\t\tcontinue;\n+\t\t}\n+\t\tlen++;\n+\t\tp++;\n+\t}\n+\tif (!force_quotes && n == 0)\n+\t\treturn arg;\n+\n+\t/* insert \\ where necessary */\n+\td = q = xmalloc(len+n+3);\n+\t*d++ = '\"';\n+\twhile (*arg) {\n+\t\tif (*arg == '\"')\n+\t\t\t*d++ = '\\\\';\n+\t\telse if (*arg == '\\\\') {\n+\t\t\tint count = 0;\n+\t\t\twhile (*arg == '\\\\') {\n+\t\t\t\tcount++;\n+\t\t\t\t*d++ = *arg++;\n+\t\t\t}\n+\t\t\tif (*arg == '\"') {\n+\t\t\t\twhile (count-- > 0)\n+\t\t\t\t\t*d++ = '\\\\';\n+\t\t\t\t*d++ = '\\\\';\n+\t\t\t}\n+\t\t}\n+\t\t*d++ = *arg++;\n+\t}\n+\t*d++ = '\"';\n+\t*d++ = 0;\n+\treturn q;\n+}\n+\n static const char *parse_interpreter(const char *cmd)\n {\n \tstatic char buf[100];\n@@ -311,6 +371,138 @@ static char *path_lookup(const char *cmd, char **path, int exe_only)\n \treturn prog;\n }\n \n+static int env_compare(const void *a, const void *b)\n+{\n+\tchar *const *ea = a;\n+\tchar *const *eb = b;\n+\treturn strcasecmp(*ea, *eb);\n+}\n+\n+static pid_t mingw_spawnve(const char *cmd, const char **argv, char **env,\n+\t\t\t int prepend_cmd)\n+{\n+\tSTARTUPINFO si;\n+\tPROCESS_INFORMATION pi;\n+\tstruct strbuf envblk, args;\n+\tunsigned flags;\n+\tBOOL ret;\n+\n+\t/* Determine whether or not we are associated to a console */\n+\tHANDLE cons = CreateFile(\"CONOUT$\", GENERIC_WRITE,\n+\t\t\tFILE_SHARE_WRITE, NULL, OPEN_EXISTING,\n+\t\t\tFILE_ATTRIBUTE_NORMAL, NULL);\n+\tif (cons == INVALID_HANDLE_VALUE) {\n+\t\t/* There is no console associated with this process.\n+\t\t * Since the child is a console process, Windows\n+\t\t * would normally create a console window.

That was the usage I had in mind.\n\nThe problem with the two others you suggested (basically that the reviewer \nherself sends out another patch series) is a little fragile, since a \nmalicous reviewer could add/modify code, but for nice reviewers, it is \nbetter in that you know which code was reviewed.\n\nSo I'd rather have it not resent by the reviewer as a patch series, but I \nthink that pulling it is fine, since it is much easier to verify (with log \n--cherry-pick) that no code was tampered with by the reviewer.\n\n> You probably meant that that is the expected workflow, as you can give \n> more than one of these options.\n> \n> But people who read the documentation should not have to guess.\n\nFrankly, I did not make up my mind on the other workflows, I only wanted \nto make the maintainer's life (yours) easier.\n\nI have no problem posting several revisions of this patch, or scrap it \naltogether... as somebody recently said, we even joke around here via \npatches ;-)\n\n> > diff --git a/t/t4014-format-patch.sh b/t/t4014-format-patch.sh\n> > index b2b7a8d..e2ff94f 100755\n> > --- a/t/t4014-format-patch.sh\n> > +++ b/t/t4014-format-patch.sh\n> > @@ -230,4 +230,30 @@ test_expect_success 'shortlog of cover-letter wraps overly-long onelines' '\n> > \n> > '\n> > \n> > +cat > expect << EOF\n> > +\n> > +Reviewed-by: Ken Robinson\n> > +\n> > +Reviewed-by: Sergey Rachmaninov\n> > +\n> > +Reviewed-by: Ronny O Sullivan\n> > +Reviewed-by: Mickey Mouse\n> > +Reviewed-by: Mahatma Gandhi\n> > +EOF\n> > +\n> > +test_expect_success '--reviewed-by' '\n> > +\n> > +\techo reviewed > foo &&\n> > +\ttest_tick &&\n> > +\tgit commit -m \"Reviewed\" -m \"Reviewed-by: Ken Robinson\" \\\n> > +\t\t-m \"Reviewed-by: Sergey Rachmaninov\" \\\n> > +\t\t-m \"Reviewed-by: Ronny O Sullivan\" foo &&\n> > +\tgit format-patch --reviewed-by=\"Mickey Mouse\" \\\n> > +\t\t--reviewed-by=\"Sergey Rachmaninov\" \\\n> > +\t\t--reviewed-by=\"Mahatma Gandhi\" -1 HEAD &&\n> > +\tsed -e \"1,/^Cc: /d\" -e \"/^---/,\\$d\" < 0001-Reviewed.patch > output &&\n> > +\tgit diff expect output\n> > +\n> > +'\n> \n> Why not use a single -m for the first three reviewed-bys, instead of\n> making them into separate paragraphs using multiple -m?\n\nI am always unsure how to embed newlines in strings in a shell script \n(except with single-ticks), and besides, I do not like breaking the \nindentation.

IIRC the first 8 parameters are passed by a so-called \nregister window, which changes with each function call.\n\nSo no, I think there is no portable way to pass them around.\n\nOf course, having a simple implementation for addf() _not_ using \nvsnprintf() could help, too (and make the process more efficient, \nprobably).\n\nI thought.\n\nThe formats we'd have to support are:\n\n$ git grep strbuf_addf |\n\tsed -e 's/^[^\"]*\"\\([^\"]*\\)\".*$/\\1/' -e 's/%%//g' -e 's/%/\\\n&/g' | sed -n -e 's/\\(%[^a-zA-Z]*[a-zA-Z]\\).*/\\1/p' | sort | uniq\n\n%02X\n%06o\n%c\n%d\n%l\n%o\n%s\n%.*s\n%u\n\nSo it does not look too bad. 'X', 'o', 'd', 'l' and 'u', possibly with a \nsize specifier (left 0-padded), 'c' and 's' (possibly with a length \nparameter).\n\nThe implementation wouldn't be _too_ short, I'd say, but doable.\n\nCiao,\nDscho\n\n"},{"id":"71252","messageId":"alpine.LSU.1.00.0803061727120.3941@racer.site","threadId":"12344","inReplyTo":"alpine.LSU.1.00.0803061319590.15786@racer.site","subject":"[PATCH 1/2 v2] Add strbuf_vaddf(), use it in strbuf_addf(), and add strbuf_initf()","fromName":"Johannes Schindelin","fromEmail":"johannes.schindelin@gmx.de","sentAt":"2008-03-06T16:29:50Z","receivedAt":"2008-03-06T16:29:50Z","isPatch":true,"sender":{"key":"johannes.schindelin@gmx.de","avatar":"https://avatars.githubusercontent.com/u/127790?v=4"},"body":"\nThe most common use of addf() was to init a strbuf and addf() right away.\nSince it is so common, it makes sense to have a function strbuf_initf() to\nwrap both calls into one.\n\nTo do that, we implement a (really minimal) vaddf() lookalike to\nvsprintf().\n\nAt the moment, it only handles %u, %i, %d, %l, %o, %x and %X with size\nindicators '', ' ' and '0', as well as %c and %s,\nthe latter with size indicators '.*' in addition to the same size\nindicators as for numbers.\n\nSigned-off-by: Johannes Schindelin \n---\n\n\tOn Thu, 6 Mar 2008, Johannes Schindelin wrote:\n\n\t> Of course, having a simple implementation for addf() _not_ using \n\t> vsnprintf() could help, too (and make the process more efficient, \n\t> probably).\n\n\tHaving thought about this a bit, I came up with this \n\timplementation (replacing my earlier PATCH 1/2).

But the recent patch for vsnprintf[1] doesn't actually fix the\nproblem of reusing va_args in the general case; the va_list argument,\nap, is undefined after the vsnprintf() call, yet it calls it in a loop.\nJust bite the bullet and pull in va_copy.

I had to make \nhas_dos_drive_prefix a macro; otherwise we would get numerous warnings \nabout \"undeclared function isalpha\", because the declaration appears later in \ngit-compat-util.h.\n\nOn the positive side, we can now reuse Michal's vsnprintf wrapper, which fixes \nsnprintf, too, (which was not the case previously). Note that on Windows we \nhave to adjust the size parameter.\n\nThere's also a change in the setup of stderr in start_command() that \ncorresponds to ce2cf27adc. And I made is_dir_sep into a conditional macro \nsimilar to has_dos_drive_prefix to get rid of another #ifdef/#endif.\n\n-- Hannes\n\nHere's the interdiff:\n\ndiff --git a/Makefile b/Makefile\nindex 68d60e7..6619523 100644\n--- a/Makefile\n+++ b/Makefile\n@@ -309,7 +309,7 @@ LIB_H = \\\n \ttree-walk.h log-tree.h dir.h path-list.h unpack-trees.h builtin.h \\\n \tutf8.h reflog-walk.h patch-ids.h attr.h decorate.h progress.h \\\n \tmailmap.h remote.h parse-options.h transport.h diffcore.h hash.h fsck.h \\\n-\tpack-revindex.h\n+\tpack-revindex.h compat/mingw.h\n \n DIFF_OBJS = \\\n \tdiff.o diff-lib.o diffcore-break.o diffcore-order.o \\\n@@ -549,10 +549,12 @@ ifneq (,$(findstring MINGW,$(uname_S)))\n \tNO_C99_FORMAT = YesPlease\n \tNO_STRTOUMAX = YesPlease\n \tNO_MKDTEMP = YesPlease\n+\tSNPRINTF_RETURNS_BOGUS = YesPlease\n \tNO_SVN_TESTS = YesPlease\n \tNO_PERL_MAKEMAKER = YesPlease\n \tNO_POSIX_ONLY_PROGRAMS = YesPlease\n \tCOMPAT_CFLAGS += -D__USE_MINGW_ACCESS -DNOGDI -Icompat\n+\tCOMPAT_CFLAGS += -DSNPRINTF_SIZE_CORR=1\n \tCOMPAT_CFLAGS += -DSTRIP_EXTENSION=\\\".exe\\\"\n \tCOMPAT_OBJS += compat/mingw.o compat/fnmatch.o compat/regex.o\n \tEXTLIBS += -lws2_32\ndiff --git a/compat/mingw.c b/compat/mingw.c\nindex 6733727..7c8fd0e 100644\n--- a/compat/mingw.c\n+++ b/compat/mingw.c\n@@ -847,40 +847,6 @@ int mingw_rename(const char *pold, const char *pnew)\n \treturn -1;\n }\n \n-#undef vsnprintf\n-/* Note that the size parameter specifies the available space, i.e.\n- * includes the trailing NUL byte; but Windows's vsnprintf expects the\n- * number of characters to write without the trailing NUL.\n- */\n-\n-/* This is out of line because it uses alloca() behind the scenes,\n- * which must not be called in a loop (alloca() reclaims the allocations\n- * only at function exit).\n- */\n-static int try_vsnprintf(size_t size, const char *fmt, va_list args)\n-{\n-\tchar buf[size];\t/* gcc-ism */\n-\treturn vsnprintf(buf, size-1, fmt, args);\n-}\n-\n-int mingw_vsnprintf(char *buf, size_t size, const char *fmt, va_list args)\n-{\n-\tint len;\n-\tif (size > 0) {\n-\t\tlen = vsnprintf(buf, size-1, fmt, args);\n-\t\tif (len >= 0)\n-\t\t\treturn len;\n-\t}\n-\t/* ouch, buffer too small; need to compute the size */\n-\tif (size < 250)\n-\t\tsize = 250;\n-\tdo {\n-\t\tsize *= 4;\n-\t\tlen = try_vsnprintf(size, fmt, args);\n-\t} while (len < 0);\n-\treturn len;\n-}\n-\n struct passwd *getpwuid(int uid)\n {\n \tstatic char user_name[100];\ndiff --git a/compat/mingw.h b/compat/mingw.h\nindex d92c631..c7db345 100644\n--- a/compat/mingw.h\n+++ b/compat/mingw.h\n@@ -174,9 +174,6 @@ int mingw_fstat(int fd, struct mingw_stat *buf);\n static inline int mingw_stat(const char *file_name, struct mingw_stat *buf)\n { return mingw_lstat(file_name, buf); }\n \n-int mingw_vsnprintf(char *buf, size_t size, const char *fmt, va_list args);\n-#define vsnprintf mingw_vsnprintf\n-\n pid_t mingw_spawnvpe(const char *cmd, const char **argv, char **env);\n void mingw_execvp(const char *cmd, char *const *argv);\n #define execvp mingw_execvp\n@@ -192,12 +189,8 @@ sig_handler_t mingw_signal(int sig, sig_handler_t \nhandler);\n * git specific compatibility\n */\n \n-static inline int has_dos_drive_prefix(const char *path)\n-{\n-\treturn isalpha(*path) && path[1] == ':';\n-}\n-#define has_dos_drive_prefix has_dos_drive_prefix\n-\n+#define has_dos_drive_prefix(path) (isalpha(*(path)) && (path)[1] == ':')\n+#define is_dir_sep(c) ((c) == '/' || (c) == '\\\\')\n #define PATH_SEP ';'\n #define PRIuMAX \"I64u\"\n \ndiff --git a/compat/snprintf.c b/compat/snprintf.c\nindex dbfc2d6..480b66f 100644\n--- a/compat/snprintf.c\n+++ b/compat/snprintf.c\n@@ -1,12 +1,21 @@\n #include \"../git-compat-util.h\"\n \n+/*\n+ * The size parameter specifies the available space, i.e. includes\n+ * the trailing NUL byte; but Windows's vsnprintf expects the\n+ * number of characters to write without the trailing NUL.\n+ */\n+#ifndef SNPRINTF_SIZE_CORR\n+#define SNPRINTF_SIZE_CORR 0\n+#endif\n+\n #undef vsnprintf\n int git_vsnprintf(char *str, size_t maxsize, const char *format, va_list ap)\n {\n \tchar *s;\n \tint ret;\n \n-\tret = vsnprintf(str, maxsize, format, ap);\n+\tret = vsnprintf(str, maxsize-SNPRINTF_SIZE_CORR, format, ap);\n \tif (ret != -1)\n \t\treturn ret;\n \n@@ -20,7 +29,7 @@ int git_vsnprintf(char *str, size_t maxsize, const char \n*format, va_list ap)\n \t\tif (!
