2012-12-19git-compat-util.h: do not #include <sys/param.h> by defaultLibravatar Junio C Hamano1-1/+1
Earlier we allowed platforms that lack <sys/param.h> not to include the header file from git-compat-util.h; we have included this header file since the early days back when we used MAXPATHLEN (which we no longer use) and also depended on it slurping ULONG_MAX (which we get by including stdint.h or inttypes.h these days). It turns out that we can compile our modern codebase just file without including it on many platforms (so far, Fedora, Debian, Ubuntu, MinGW, Mac OS X, Cygwin, HP-Nonstop, QNX and z/OS are reported to be OK). Let's stop including it by default, and on platforms that need it to be included, leave "make NEEDS_SYS_PARAM_H=YesPlease" as an escape hatch and ask them to report to us, so that we can find out about the real dependency and fix it in a more platform agnostic way.

2012-12-15make error()'s constant return value more visibleLibravatar Jeff King1-0/+11
When git is compiled with "gcc -Wuninitialized -O3", some inlined calls provide an additional opportunity for the compiler to do static analysis on variable initialization. For example, with two functions like this: int get_foo(int *foo) { if (something_that_might_fail() < 0) return error("unable to get foo"); *foo = 0; return 0; } void some_fun(void) { int foo; if (get_foo(&foo) < 0) return -1; printf("foo is %d\n", foo); } If get_foo() is not inlined, then when compiling some_fun, gcc sees only that a pointer to the local variable is passed, and must assume that it is an out parameter that is initialized after get_foo returns. However, when get_foo() is inlined, the compiler may look at all of the code together and see that some code paths in get_foo() do not initialize the variable. As a result, it prints a warning. But what the compiler can't see is that error() always returns -1, and therefore we know that either we return early from some_fun, or foo ends up initialized, and the code is safe. The warning is a false positive. If we can make the compiler aware that error() will always return -1, it can do a better job of analysis. The simplest method would be to inline the error() function. However, this doesn't work, because gcc will not inline a variadc function. We can work around this by defining a macro. This relies on two gcc extensions: 1. Variadic macros (these are present in C99, but we do not rely on that). 2. Gcc treats the "##" paste operator specially between a comma and __VA_ARGS__, which lets our variadic macro work even if no format parameters are passed to error(). Since we are using these extra features, we hide the macro behind an #ifdef. This is OK, though, because our goal was just to help gcc.

RFC 2047 requires more characters to be encoded than it is currently done. Especially, RFC 2047 distinguishes between allowed remaining characters in encoded words in addresses (From, To, etc.) and other headers, such as Subject. Make add_rfc2047() and is_rfc2047_special() location dependent and include all non-allowed characters to hopefully be RFC 2047 conformant. This especially fixes a problem, where RFC 822 specials (e. g. ".") were left unencoded in addresses, which was solved with a non-standard-conforming workaround in the past (which is going to be removed in a follow-up patch). Signed-off-by: Jan H.

2012-10-13config: treat user and xdg config permission problems as errorsLibravatar Jonathan Nieder1-0/+1
Git reads multiple configuration files: settings come first from the system config file (typically /etc/gitconfig), then the xdg config file (typically ~/.config/git/config), then the user's dotfile (~/.gitconfig), then the repository configuration (.git/config). Git has always used access(2) to decide whether to use each file; as an unfortunate side effect, that means that if one of these files is unreadable (e.g., EPERM or EIO), git skips it. So if I use ~/.gitconfig to override some settings but make a mistake and give it the wrong permissions then I am subject to the settings the sysadmin chose for /etc/gitconfig. Better to error out and ask the user to correct the problem. This only affects the user and xdg config files, since the user presumably has enough access to fix their permissions. If the system config file is unreadable, the best we can do is to warn about it so the user knows to notify someone and get on with work in the meantime.

The access_or_warn() function is used to check for optional configuration files like .gitconfig and .gitignore and warn when they are not accessible due to a configuration issue (e.g., bad permissions). It is not supposed to complain when a file is simply missing. Noticed on a system where ~/.config/git was a file --- when the new XDG_CONFIG_HOME support looks for ~/.config/git/config it should ignore ~/.config/git instead of printing irritating warnings: $ git status -s warning: unable to access '/home/jrn/.config/git/config': Not a directory warning: unable to access '/home/jrn/.config/git/config': Not a directory warning: unable to access '/home/jrn/.config/git/config': Not a directory warning: unable to access '/home/jrn/.config/git/config': Not a directory Compare v1.7.12.1~2^2 (attr:failure to open a .gitattributes file is OK with ENOTDIR, 2012-09-13).

The current code uses setitimer() only for reducing perceived latency. On platforms that lack setitimer() (e.g. HP NonStop), allow builders to say "make NO_SETITIMER=YesPlease" to use a no-op substitute, as doing so would not affect correctness. HP NonStop does provide struct itimerval, but other platforms may not, so this is taken care of in this commit too, by setting NO_STRUCT_ITIMERVAL.

2012-08-21warn_on_inaccessible(): a helper to warn on inaccessible pathsLibravatar Junio C Hamano1-0/+3
The previous series introduced warnings to multiple places, but it could become tiring to see the warning on the same path over and over again during a single run of Git. Making just one function responsible for issuing this warning, we could later choose to keep track of which paths we issued a warning (it would involve a hash table of paths after running them through real_path() or something) in order to reduce noise. Right now we do not know if the noise reduction is necessary, but it still would be a good code reduction/sharing anyway. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-08-21config: warn on inaccessible filesLibravatar Jeff King1-0/+3
Before reading a config file, we check "!access(path, R_OK)" to make sure that the file exists and is readable. If it's not, then we silently ignore it. For the case of ENOENT, this is fine, as the presence of the file is optional. For other cases, though, it may indicate a configuration error (e.g., not having permissions to read the file). Let's print a warning in these cases to let the user know. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-07-08git on Mac OS and precomposed unicodeLibravatar Torsten Bögershausen1-0/+9
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.

2012-05-22ident: report passwd errors with a more friendly messageLibravatar Jeff King1-0/+3
When getpwuid fails, we give a cute but cryptic message. While it makes sense if you know that getpwuid or identity functions are being called, this code is triggered behind the scenes by quite a few git commands these days (e.g., receive-pack on a remote server might use it for a reflog; the current message is hard to distinguish from an authentication error). Let's switch to something that gives a little more context. While we're at it, we can factor out all of the cut-and-pastes of the "you don't exist" message into a wrapper function. Rather than provide xgetpwuid, let's make it even more specific to just getting the passwd entry for the current uid. That's the only way we use getpwuid anyway, and it lets us make an even more specific error message. The current message also fails to mention errno. While the usual cause for getpwuid failing is that the user does not exist, mentioning errno makes it easier to diagnose these problems. Note that POSIX specifies that errno remain untouched if the passwd entry does not exist (but will be set on actual errors), whereas some systems will return ENOENT or similar for a missing entry. We handle both cases in our wrapper. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In particular, sparse complains as follows: SP ctype.c ctype.c:30:12: warning: symbol 'tolower_trans_tbl' was not declared.\ Should it be static? An appropriate extern declaration for the 'tolower_trans_tbl' symbol is included in the "cache.h" header file. In order to suppress the warning, therefore, we could replace the "git-compat-util.h" header inclusion with "cache.h", since "cache.h" includes "git-compat-util.h" in turn. Here, however, we choose to move the extern declaration for 'tolower_trans_tbl' into "git-compat-util.h", alongside the other extern declaration from ctype.c for 'sane_ctype'.

The earlier design was to take whatever non-alnum that the short format parser happens to support, leaving the rest as part of the pattern, so a version of git that knows '*' magic and a version that does not would have behaved differently when given ":*Makefile". The former would have applied the '*' magic to the pattern "Makefile", while the latter would used no magic to the pattern "*Makefile". Instead, just reserve all non-alnum ASCII letters that are neither glob nor regexp special as potential magic signature, and when we see a magic that is not supported, die with an error message, just like the longhand codepath does. With this, ":%#!*Makefile" will always mean "%#!" magic applied to the pattern "*Makefile", no matter what version of git is used (it is a different matter if the version of git supports all of these three magic matching rules). Also make ':' without anything else to mean "there is no pathspec". This would allow differences between "git log" and "git log ." run from the top level of the working tree (the latter simplifies no-op commits away from the history) to be expressed from a subdirectory by saying "git log :".

2011-04-03compat: add missing #include <sys/resource.h>Libravatar Jonathan Nieder1-0/+1
Starting with commit c793430 (Limit file descriptors used by packs, 2011-02-28), git uses getrlimit to tell how many file descriptors it can use. Unfortunately it does not include the header declaring that function, resulting in compilation errors: sha1_file.c: In function 'open_packed_git_1': sha1_file.c:718: error: storage size of 'lim' isn't known sha1_file.c:721: warning: implicit declaration of function 'getrlimit' sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function) sha1_file.c:718: warning: unused variable 'lim' The standard header to include for this is <sys/resource.h> (which on some systems itself requires declarations from <sys/types.h> or <sys/time.h>). Probably the problem was missed until now because in current glibc sys/resource.h happens to be included by sys/wait.h. MinGW does not provide sys/resource.h (and compat/mingw takes care of providing getrlimit some other way), so add the missing #include to the "#ifndef __MINGW32__" block in git-compat-util.h.

2011-03-08compat: fall back on __va_copy if availableLibravatar Jonathan Nieder1-1/+10
Since an obvious implementation of va_list is to make it a pointer into the stack frame, implementing va_copy as "dst = src" will work on many systems. Platforms that use something different (e.g., a size-1 array of structs, to be assigned with *(dst) = *(src)) will need some other compatibility macro, though. Luckily, as the glibc manual hints, such systems tend to provide the __va_copy macro (introduced in GCC in March, 1997). By using that if it is available, we can cover our bases pretty well. Discovered by building with CC="gcc -std=c89" on an amd64 machine: $ make CC=c89 strbuf.o [...] strbuf.c: In function 'strbuf_vaddf': strbuf.c:211:2: error: incompatible types when assigning to type 'va_list' from type 'struct __va_list_tag *' make: *** [strbuf.o] Error 1 Explained-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-03-08git-compat-util.h: Honor HP C's noreturn attributeLibravatar Michal Rokos1-1/+4
HP C for Integrity servers (Itanium) gained support for noreturn attribute sometime in 2006. It was released in Compiler Version A.06.10 and made available in July 2006. The __HP_cc define detects the HP C compiler version. Precede the __GNUC__ check so it works well when compiling with HP C using -Agcc option that enables partial support for the GNU C dialect. The -Agcc defines the __GNUC__ too. Signed-off-by: Michal Rokos <michal.rokos@nextsoft.cz> Signed-off-by: Junio C Hamano <gitster@pobox.com>
