* symbolic-ref, update-ref: do not refuse reflog message with LFJunio C Hamano2007-07-291-2/+0
| | | | | | | | | | | | | Earlier these tools refused to create a reflog entry when the message given by the calling Porcelain had a LF in it, partially to keep the file format integrity of reflog file, which is one-entry-per-line. These tools should not be dictating such a policy. Instead, let the codepath to write out the reflog entry worry about the format integrity and allow messages with LF in them.

* Fix git-fetch while on detached HEAD not to give needlessly alarming errorsJunio C Hamano2007-01-151-5/+29
| | | | | | | | | | | | | | | | | When we are on a detached HEAD, there is no current branch. There is no reason to leak the error messages to the end user since this is a situation we expect to see. This adds -q option to git-symbolic-ref to exit without issuing an error message if the given name is not a symbolic ref. By the way, with or without this patch, there currently is no good way to tell failure modes between "git symbolic-ref HAED" and "git symbolic-ref HEAD". Both says "is not a symbolic ref". We may want to do something about it. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Tell between packed, unpacked and symbolic refs.Junio C Hamano2006-09-201-1/+5
| | | | | | | | | 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>
* symbolit-ref: fix resolve_ref conversion.Junio C Hamano2006-09-201-1/+1
| | | | | | | | An earlier conversion accidentally hardcoded "HEAD" to be passed to resolve_ref(), thereby causing git-symbolic-ref command to always report where the HEAD points at, ignoring the command line parameter. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Make ref resolution sanerLinus Torvalds2006-09-171-9/+5
| | | | | | | | | | | | | | | | 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>
* Replace uses of strdup with xstrdup.Shawn Pearce2006-09-021-2/+2
| | | | | | | | | | | | | | | | 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.
