2011-05-20receive-pack: eliminate duplicate .have refsJeff King
When receiving a push, we advertise ref tips from any alternate repositories, in case that helps the client send a smaller pack. Since these refs don't actually exist in the destination repository, we don't transmit the real ref names, but instead use the pseudo-ref ".have". If your alternate has a large number of duplicate refs (for example, because it is aggregating objects from many related repositories, some of which will have the same tags and branch tips), then we will send each ".have $sha1" line multiple times. This is a pointless waste of bandwidth, as we are simply repeating the same fact to the client over and over. This patch eliminates duplicate .have refs early on. It does so efficiently by sorting the complete list and skipping duplicates. This has the side effect of re-ordering the .have lines by ascending sha1; this isn't a problem, though, as the original order was meaningless. There is a similar .have system in fetch-pack, but it does not suffer from the same problem. For each alternate ref we consider in fetch-pack, we actually open the object and mark it with the SEEN flag, so duplicates are automatically culled.

2011-05-20bisect: refactor sha1_array into a generic sha1 listJeff King
This is a generally useful abstraction, so let's let others make use of it. The refactoring is more or less a straight copy; however, functions and struct members have had their names changed to match string_list, which is the most similar data structure.
