Shawn Pearce	9befac470b	Replace uses of strdup with xstrdup. ... 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.

Johannes Schindelin	8fd2cb4069	Extract helper bits from c-merge-recursive work ... This backports the pieces that are not uncooked from the merge-recursive WIP we have seen earlier, to be used in git-mv rewritten in C. Signed-off-by: Junio C Hamano <junkio@cox.net>	2006-07-26 13:36:36 -07:00
