2014-10-27git-compat-util.h: support variadic macros with the XL C compilerLibravatar David Michael1-1/+1
When the XL C compiler is run with an appropriate language level or suboption, it defines a feature test macro to indicate support for variadic macros by defining __C99_MACRO_WITH_VA_ARGS C preprocessor macro. This was tested on z/OS, but it should also work on AIX according to IBM documentation. Signed-off-by: David Michael <fedora.dm0@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-10-19Handle atexit list internaly for unthreaded buildsLibravatar Etienne Buira1-0/+5
Wrap atexit()s calls on unthreaded builds to handle callback list internally. This is needed because on unthreaded builds, asyncs inherits parent's atexit() list, that gets run as soon as the async exit()s (and again at the end of async's parent process). That led to remove temporary files too early. Also remove a by-atexit-callback guard against this kind of issue in clone.c, as this patch makes it redundant. Fixes test 5537 (temporary shallow file vanished before unpack-objects could open it) BTW remove an unused variable in shallow.c.

2014-10-16isxdigit: cast input to unsigned charLibravatar Jeff King1-1/+1
Otherwise, callers must do so or risk triggering warnings -Wchar-subscript (and rightfully so; a signed char might cause us to use a bogus negative index into the hexval_table). While we are dropping the now-unnecessary casts from the caller in urlmatch.c, we can get rid of similar casts in actually parsing the hex by using the hexval() helper, which implicitly casts to unsigned (but note that we cannot implement isxdigit in terms of hexval(), as it also casts its return value to unsigned).

2014-09-18add macro REALLOC_ARRAYLibravatar René Scharfe1-0/+2
The macro ALLOC_GROW manages several aspects of dynamic memory allocations for arrays: It performs overprovisioning in order to avoid reallocations in future calls, updates the allocation size variable, multiplies the item size and thus allows users to simply specify the item count, performs the reallocation and updates the array pointer. Sometimes this is too much. Add the macro REALLOC_ARRAY, which only takes care of the latter three points and allows users to specfiy the number of items the array can store. It can increase and also decrease the size. Using the macro avoid duplicating the variable name and takes care of the item sizes automatically.

2014-07-13trace: add 'file:line' to all trace outputLibravatar Karsten Blees1-0/+4
This is useful to see where trace output came from. Add 'const char *file, int line' parameters to the printing functions and rename them to *_fl. Add trace_printf* and trace_strbuf macros resolving to the *_fl functions and let the preprocessor fill in __FILE__ and __LINE__. As the trace_printf* functions take a variable number of arguments, this requires variadic macros (i.e. '#define foo(...) foo_impl(__VA_ARGS__)'. Though part of C99, it is unclear whether older compilers support this. Thus keep the old functions and only enable variadic macros for GNUC and MSVC 2005+ (_MSC_VER 1400). This has the nice side effect that the old C-style declarations serve as documentation how the macros are to be used. Print 'file:line ' as prefix to each trace line. Align the remaining trace output at column 40 to accommodate 18 char file names + 4 digit line number (currently there are 30 *.c files of length 18 and just 11 of 19). Trace output from longer source files (e.g. builtin/receive-pack.c) will not be aligned. Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-30replace has_extension with ends_withLibravatar Jeff King1-7/+0
These two are almost the same function, with the exception that has_extension only matches if there is content before the suffix. So ends_with(".exe", ".exe") is true, but has_extension would not be. This distinction does not matter to any of the callers, though, and we can just replace uses of has_extension with ends_with. We prefer the "ends_with" name because it is more generic, and there is nothing about the function that requires it to be used for file extensions.

2014-06-30implement ends_with via strip_suffixLibravatar Jeff King1-1/+6
The ends_with function is essentially a simplified version of strip_suffix, in which we throw away the stripped length. Implementing it as an inline on top of strip_suffix has two advantages: 1. We save a bit of duplicated code. 2. The suffix is typically a string literal, and we call strlen on it. By making the function inline, many compilers can replace the strlen call with a constant.

2014-06-30add strip_suffix functionLibravatar Jeff King1-0/+27
Many callers of ends_with want to not only find out whether a string has a suffix, but want to also strip it off. Doing that separately has two minor problems: 1. We often run over the string twice (once to find the suffix, and then once more to find its length to subtract the suffix length). 2. We have to specify the suffix length again, which means either a magic number, or repeating ourselves with strlen("suffix"). Just as we have skip_prefix to avoid these cases with starts_with, we can add a strip_suffix to avoid them with ends_with. Note that we add two forms of strip_suffix here: one that takes a string, with the resulting length as an out-parameter; and one that takes a pointer/length pair, and reuses the length as an out-parameter. The latter is more efficient when the caller already has the length (e.g., when using strbufs), but it can be easy to confuse the two, as they take the same number and types of parameters. For that reason, the "mem" form puts its length parameter next to the buffer (since they are a pair), and the string form puts it at the end (since it is an out-parameter). The compiler can notice when you get the order wrong, which should help prevent writing one when you meant the other.

2014-06-20refactor skip_prefix to return a booleanLibravatar Jeff King1-4/+23
The skip_prefix() function returns a pointer to the content past the prefix, or NULL if the prefix was not found. While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched. This lets you write: if (skip_prefix(arg, "foo ", &arg)) do_foo(arg); else if (skip_prefix(arg, "bar ", &arg)) do_bar(arg); Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Read-only operations such as "git status" that internally refreshes the index write out the refreshed index to the disk to optimize future accesses to the working tree, but this could race with a "read-write" operation that modify the index while it is running. Detect such a race and avoid overwriting the index. Duy raised a good point that we may need to do the same for the normal writeout codepath, not just the "opportunistic" update codepath. While that is true, nobody sane would be running two simultaneous operations that are clearly write-oriented competing with each other against the same index file.

2014-05-06let clang use the constant-return error() macroLibravatar Jeff King1-1/+1
Commit e208f9c converted error() into a macro to make its constant return value more apparent to calling code. Commit 5ded807 prevents us using this macro with clang, since clang's -Wunused-value is smart enough to realize that the constant "-1" is useless in some contexts. However, since the last commit puts the constant behind an inline function call, this is enough to prevent the -Wunused-value warning on both modern gcc and clang. So we can now re-enable the macro when compiling with clang. Tested with clang 3.3, 3.4, and 3.5. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-05-06inline constant return from error() functionLibravatar Jeff King1-1/+5
Commit e208f9c introduced a macro to turn error() calls into: (error(), -1) to make the constant return value more visible to the calling code (and thus let the compiler make better decisions about the code). This works well for code like: return error(...); but the "-1" is superfluous in code that just calls error() without caring about the return value. In older versions of gcc, that was fine, but gcc 4.9 complains with -Wunused-value. We can work around this by encapsulating the constant return value in a static inline function, as gcc specifically avoids complaining about unused function returns unless the function has been specifically marked with the warn_unused_result attribute. We also use the same trick for config_error_nonbool and opterror, which learned the same error technique in a469a10.

In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

2014-03-21Merge branch 'dk/skip-prefix-scan-only-once'Libravatar Junio C Hamano1-2/+5
Update implementation of skip_prefix() to scan only once; given that most "prefix" arguments to the inline function are constant strings whose strlen() can be determined at the compile time, this might actually make things worse with a compiler with sufficient intelligence. * dk/skip-prefix-scan-only-once: skip_prefix(): scan prefix only once
2014-03-14Merge branch 'nd/no-more-fnmatch'Libravatar Junio C Hamano1-12/+0
We started using wildmatch() in place of fnmatch(3); complete the process and stop using fnmatch(3). * nd/no-more-fnmatch: actually remove compat fnmatch source code stop using fnmatch (either native or compat) Revert "test-wildmatch: add "perf" command to compare wildmatch and fnmatch" use wildmatch() directly without fnmatch() wrapper
