2006-11-16"git fmt-merge-msg" SIGSEGVLibravatar Linus Torvalds1-0/+2
Ok, this is a _really_ stupid case, and I don't think it matters, but hey, we should never SIGSEGV. Steps to reproduce: mkdir duh cd duh git init-db git-fmt-merge-msg < /dev/null will cause a SIGSEGV in cmd_fmt_merge_msg(), because we're doing a strncmp() with a NULL current_branch. And yeah, it's an insane schenario, and no, it doesn't really matter. The only reason I noticed was that a broken version of my "git pull" into an empty directory would cause this. This silly patch just replaces the SIGSEGV with a controlled exit with an error message. Signed-off-by: Linus Torvalds <torvalds@osdl.org> 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>
2006-09-17Make ref resolution sanerLibravatar Linus Torvalds1-5/+2
The old code used to totally mix up the notion of a ref-name and the path that that ref was associated with. That was not only horribly ugly (a number of users got the path, and then wanted to try to turn it back into a ref-name again), but it fundamnetally doesn't work at all once we do any setup where a ref doesn't have a 1:1 relationship with a particular pathname. This fixes things up so that we use the ref-name throughout, and only turn it into a pathname once we actually look it up in the filesystem. That makes a lot of things much clearer and more straightforward. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-11/+11
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.

2006-09-01fmt-merge-msg: fix off-by-one bugLibravatar Johannes Schindelin1-1/+1
Thanks to the recent malloc()->xmalloc() change, and XMALLOC_POISON, this bug was found. Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-08-27free(NULL) is perfectly valid.Libravatar Junio C Hamano1-2/+1
Jonas noticed some places say "if (X) free(X)" which is totally unnecessary. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-26Use xrealloc instead of reallocLibravatar Jonas Fonseca1-2/+2
Change places that use realloc, without a proper error path, to instead use xrealloc. Drop an erroneous error path in the daemon code that used errno in the die message in favour of the simpler xrealloc. Signed-off-by: Jonas Fonseca <fonseca@diku.dk> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-15remove unnecessary initializationsLibravatar David Rientjes1-1/+1
[jc: I needed to hand merge the changes to the updated codebase, so the result needs to be checked.] Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-29Call setup_git_directory() much earlierLibravatar Linus Torvalds1-2/+1
This changes the calling convention of built-in commands and passes the "prefix" (i.e. pathname of $PWD relative to the project root level) down to them. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-28Call setup_git_directory() earlyLibravatar Linus Torvalds1-1/+2
Any git command that expects to work in a subdirectory of a project, and that reads the git config files (which is just about all of them) needs to make sure that it does the "setup_git_directory()" call before it tries to read the config file. This means, among other things, that we need to move the call out of "init_revisions()", and into the caller. This does the mostly trivial conversion to do that.

2006-07-12Remove TYPE_* constant macros and use object_type enums consistently.Libravatar Linus Torvalds1-1/+1
This updates the type-enumeration constants introduced to reduce the memory footprint of "struct object" to match the type bits already used in the packfile format, by removing the former (i.e. TYPE_* constant macros) and using the latter (i.e. enum object_type) throughout the code for consistency. Eventually we can stop passing around the "type strings" entirely, and this will help - no confusion about two different integer enumeration.

The new C version mistranslated the original Perl version in the case to pull from the HEAD. This made it to say nonsense like this: Merge commit ...url... of HEAD * HEAD: ... Signed-off-by: Junio C Hamano <junkio@cox.net>
