Kevin Bracey	83f0412f3f	decorate.c: compact table when growing When growing the table, take the opportunity to "compact" it by removing entries with NULL decoration. Users may have "removed" decorations by passing NULL to insert_decoration. An object's table entry can't actually be removed during normal operation, as it would break the linear hash collision search. But we can remove NULL decoration entries when rebuilding the table.

Dan McGee	91fe2f9091	Unify signedness in hashing calls Our hash_obj and hashtable_index calls and functions were doing a lot of funny things with signedness. Unify all of it to 'unsigned int'.

Dan McGee	b867d324ce	Fix type-punning issues In these two places we are casting part of our unsigned char sha1 array into an unsigned int, which violates GCCs strict-aliasing rules (and probably other compilers).

Jeff King	54988bdad7	decorate: allow const objects to be decorated We don't actually modify the struct object, so there is no reason not to accept const versions (and this allows other callsites, like the next patch, to use the decoration machinery).

Junio C Hamano	6991357513	fast-export --export-marks: fix off by one error The export_marks() function iterated over a (potentially sparsely populated) hashtable, but it accessed it starting from offset 1 and one element beyond the end. Noticed by SungHyun Nam. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Linus Torvalds	2a1a3dce33	Fix a copy-n-paste bug in the object decorator code. Duh. When I did the object decorator thing, I made the "loop over the hash" function use the same logic for updating the hash, ie made them use if (++j >= size) j = 0; for both the hash update for both "insert" and "lookup" HOWEVER. For some inexplicable reason I had an extraneous j++; in the insert path (probably just from the fact that the old code there used j++; if (j >= size) j = 0; and when I made them use the same logic I just didn't remove the old extraneous line properly. This fixes it. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Linus Torvalds	a59b276e18	Add a generic "object decorator" interface, and make object refs use it This allows you to add an arbitrary "decoration" of your choice to any object. It's a space- and time-efficient way to add information to arbitrary objects, especially if most objects probably do not have the decoration.
