use skip_prefix to avoid repeating strings

2014-06-20T17:44:45Z

It's a common idiom to match a prefix and then skip past it with strlen, like: if (starts_with(foo, "bar")) foo += strlen("bar"); This avoids magic numbers, but means we have to repeat the string (and there is no compiler check that we didn't make a typo in one of the strings). We can use skip_prefix to handle this case without repeating ourselves. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

use xstrfmt in favor of manual size calculations

2014-06-19T19:25:17Z

In many parts of the code, we do an ugly and error-prone malloc like: const char *fmt = "something %s"; buf = xmalloc(strlen(foo) + 10 + 1); sprintf(buf, fmt, foo); This makes the code brittle, and if we ever get the allocation wrong, is a potential heap overflow. Let's instead favor xstrfmt, which handles the allocation automatically, and makes the code shorter and more readable. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

Use starts_with() for C strings instead of memcmp()

2014-06-09T21:38:12Z

Convert three cases of checking for a constant prefix using memcmp() to starts_with(). This way there is no need for magic string length constants and we avoid running over the end of the string should it be shorter than the prefix. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

remote.c: rearrange xcalloc arguments

2014-05-27T21:02:45Z

xcalloc() takes two arguments: the number of elements and their size. parse_refspec_internal passes the arguments in reverse order, passing the size of a refspec, followed by the number to allocate. Rearrange them so they are in the correct order. Signed-off-by: Brian Gesiak Signed-off-by: Junio C Hamano

Merge branch 'jl/nor-or-nand-and'

2014-04-08T19:00:28Z

Eradicate mistaken use of "nor" (that is, essentially "nor" used not in "neither A nor B" ;-)) from in-code comments, command output strings, and documentations. * jl/nor-or-nand-and: code and test: fix misuses of "nor" comments: fix misuses of "nor" contrib: fix misuses of "nor" Documentation: fix misuses of "nor"

Merge branch 'cn/fetch-prune-overlapping-destination'

2014-04-03T19:38:18Z

Protect refs in a hierarchy that can come from more than one remote hierarcies from incorrect removal by "git fetch --prune". * cn/fetch-prune-overlapping-destination: fetch: handle overlaping refspecs on --prune fetch: add a failing test for prunning with overlapping refspecs
