2006-09-02Replace uses of strdup with xstrdup.Shawn Pearce
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.

2006-08-23hashcpy/hashcmp remaining bits.Junio C Hamano
This fixes up merge-recursive.c for hashcpy/hashcmp changes. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-23Convert memcpy(a,b,20) to hashcpy(a,b).Shawn Pearce
This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: this is a follow-up patch for merge-recursive.c which is not in "master" yet. The original was sent-in for "next" so I splitted it out. ] Signed-off-by: Shawn O.

Adjust to hold_lock_file_for_update() change on the master.
2006-08-09merge-recur: do not die unnecessarilyJohannes Schindelin
When the cache is dirty, and we switch the index file from temporary to final, we want to discard the cache without complaint. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-09merge-recur: try to merge older merge bases firstJohannes Schindelin
It seems to be the only sane way to do it: when a two-head merge is done, and the merge-base and one of the two branches agree, the merge assumes that the other branch has something new. If we start creating virtual commits from newer merge-bases, and go back to older merge-bases, and then merge with newer commits again, chances are that a patch is lost, _because_ the merge-base and the head agree on it. Unlikely, yes, but it happened to me. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-09merge-recur: if there is no common ancestor, fake empty oneJohannes Schindelin
This fixes the coolest merge ever. [jc: with two "Oops that's not it" fixes from Johannes and Alex, and an obvious type mismatch fix.] Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-09merge-recur: do not setenv("GIT_INDEX_FILE")Johannes Schindelin
Since there are no external calls left in merge-recur, we do not need to set the environment variable GIT_INDEX_FILE all the time. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-09merge-recur: do not call git-write-treeJohannes Schindelin
Since merge-recur is in C, and uses libgit, it can call the relevant functions directly, without writing the index file. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-04merge-recursive: fix rename handlingJohannes Schindelin
To handle renames properly, we iterate through all file names of both heads, the current one, and the one to be merged. Only that there was a bug, where it was checked if the file name was present in both heads, but the result of the check was never used. Instead, the merge proceeded as if both heads contained that file. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-31merge-recur: virtual commits shall never be parsedJohannes Schindelin
It would not make sense to parse a virtual commit, therefore set the "parsed" flag to 1. Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-30merge-recur: fix thinko in unique_path()Johannes Schindelin
This could result in a nasty infinite loop, or in bogus names (it used the strlen() of the newly allocated buffer instead of the original buffer). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-28merge-recur: Explain why sha_eq() and struct stage_data cannot goJohannes Schindelin
There were two TODOs to remove sha_eq() and to convert users of struct stage_data to active_cache users, but this is not possible. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-28Cumulative update of merge-recursive in CJohannes Schindelin

2006-07-14Status update on merge-recursive in CJohannes Schindelin
This is just an update for people being interested. Alex and me were busy with that project for a few days now. While it has progressed nicely, there are quite a couple TODOs in merge-recursive.c, just search for "TODO". For impatient people: yes, it passes all the tests, and yes, according to the evil test Alex did, it is faster than the Python script. But no, it is not yet finished. Biggest points are: - there are still three external calls - in the end, it should not be necessary to write the index more than once (just before exiting) - a lot of things can be refactored to make the code easier and shorter BTW we cannot just plug in git-merge-tree yet, because git-merge-tree does not handle renames at all. This patch is meant for testing, and as such, - it compile the program to git-merge-recur - it adjusts the scripts and tests to use git-merge-recur instead of git-merge-recursive - it provides "TEST", a script to execute the tests regarding -recursive - it inlines the changes to read-cache.c (read_cache_from(), discard_cache() and refresh_cache_entry()) Brought to you by Alex Riesen and Dscho Signed-off-by: Junio C Hamano <junkio@cox.net>
