2016-02-22use xmallocz to avoid size arithmeticJeff King
We frequently allocate strings as xmalloc(len + 1), where the extra 1 is for the NUL terminator. This can be done more simply with xmallocz, which also checks for integer overflow. There's no case where switching xmalloc(n+1) to xmallocz(n) is wrong; the result is the same length, and malloc made no guarantees about what was in the buffer anyway. But in some cases, we can stop manually placing NUL at the end of the allocated buffer. But that's only safe if it's clear that the contents will always fill the buffer. In each case where this patch does so, I manually examined the control flow, and I tried to err on the side of caution. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2015-01-14standardize usage info string formatAlex Henrie
This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <> Reviewed-by: Matthieu Moy <> Signed-off-by: Junio C Hamano <>
2011-10-05Change check_refname_format() to reject unnormalized refnamesMichael Haggerty
Since much of the infrastructure does not work correctly with unnormalized refnames, change check_refname_format() to reject them. Similarly, change "git check-ref-format" to reject unnormalized refnames by default. But add an option --normalize, which causes "git check-ref-format" to normalize the refname before checking its format, and print the normalized refname. This is exactly the behavior of the old --print option, which is retained but deprecated. Signed-off-by: Michael Haggerty <> Signed-off-by: Junio C Hamano <>

2011-10-05Change check_ref_format() to take a flags argumentMichael Haggerty
Change check_ref_format() to take a flags argument that indicates what is acceptable in the reference name (analogous to "git check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This is more convenient for callers and also fixes a failure in the test suite (and likely elsewhere in the code) by enabling "onelevel" and "refspec-pattern" to be allowed independently of each other. Also rename check_ref_format() to check_refname_format() to make it obvious that it deals with refnames rather than references themselves.

2011-10-05git check-ref-format: add options --allow-onelevel and --refspec-patternMichael Haggerty
Also add tests of the new options. (Actually, one big reason to add the new options is to make it easy to test check_ref_format(), though the options should also be useful to other scripts.) Interpret the result of check_ref_format() based on which types of refnames are allowed. However, because check_ref_format() can only return a single value, one test case is still broken. Specifically, the case "git check-ref-format --onelevel '*'" incorrectly succeeds because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this refname even though the refname is also CHECK_REF_FORMAT_WILDCARD. The type of check that leads to this failure is used elsewhere in "real" code and could lead to bugs; it will be fixed over the next few commits.

2011-08-25check-ref-format --print: Normalize refnames that start with slashesMichael Haggerty
When asked if "refs///heads/master" is valid, check-ref-format says "Yes, it is well formed", and when asked to print canonical form, it shows "refs/heads/master". This is so that it can be tucked after "$GIT_DIR/" to form a valid pathname for a loose ref, and we normalize a pathname like "$GIT_DIR/refs///heads/master" to de-dup the slashes in it. Similarly, when asked if "/refs/heads/master" is valid, check-ref-format says "Yes, it is Ok", but the leading slash is not removed when printing, leading to "$GIT_DIR//refs/heads/master". Fix it to make sure such leading slashes are removed. Add tests that such refnames are accepted and normalized correctly. Signed-off-by: Michael Haggerty <> Signed-off-by: Junio C Hamano <>

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
