2007-02-20Mechanical conversion to use prefixcmp()Libravatar Junio C Hamano1-4/+4
This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-02-19name-rev: avoid "^0" when unneededLibravatar Johannes Schindelin1-7/+16
When naming by a tag, we used to add "^0" even if this was not really necessary. For example, `git name-rev de6f0def` now outputs de6f0def tags/v1.5.0.1~9 instead of de6f0def tags/v1.5.0.1^0~9 Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-02-17name-rev: introduce the --refs=<pattern> optionLibravatar Johannes Schindelin1-6/+17
Instead of (or, in addition to) --tags, to use only tags for naming, you can now use --refs=<pattern> to specify a shell glob pattern which the refs must match to be used for naming. Example: $ git name-rev --refs=*v1* 33db5f4d 33db5f4d tags/v1.0rc1^0~1593 Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-20simplify inclusion of system header files.Libravatar Junio C Hamano1-1/+0
This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-20Tell between packed, unpacked and symbolic refs.Libravatar Junio C Hamano1-1/+1
This adds a "int *flag" parameter to resolve_ref() and makes for_each_ref() family to call callback function with an extra "int flag" parameter. They are used to give two bits of information (REF_ISSYMREF and REF_ISPACKED) about the ref. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-20Add callback data to for_each_ref() family.Libravatar Junio C Hamano1-4/+4
This is a long overdue fix to the API for for_each_ref() family of functions. It allows the callers to specify a callback data pointer, so that the caller does not have to use static variables to communicate with the callback funciton. The updated for_each_ref() family takes a function of type int (*fn)(const char *, const unsigned char *, void *) and a void pointer as parameters, and calls the function with the name of the ref and its SHA-1 with the caller-supplied void pointer as parameters. The commit updates two callers, builtin-name-rev.c and builtin-pack-refs.c as an example. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-1/+1
Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O.
