For historical reasons, the exact rename detection had populated the filespecs for the entries it compared, and the rest of the similarity analysis depended on that. I hadn't even bothered to debug why that was the case when I re-did the rename detection, I just made the new one have the same broken behaviour, with a note about this special case. This fixes that fixme. The reason the exact rename detector needed to fill in the file sizes of the files it checked was that the _inexact_ rename detector was broken, and started comparing file sizes before it filled them in. Fixing that allows the exact phase to do the sane thing of never even caring (since all *it* cares about is really just the SHA1 itself, not the size nor the contents). It turns out that this also indirectly fixes a bug: trying to populate all the filespecs will run out of virtual memory if there is tons and tons of possible rename options. The fuzzy similarity analysis does the right thing in this regard, and free's the blob info after it has generated the hash tables, so the special case code caused more trouble than just some extra illogical code.

//////////////////////////////////////////////////////////////// GIT - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, depending on your mood. - random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant. - stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang. - "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room. - "goddamn idiotic truckload of sh*t": when it breaks Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. Git is an Open Source project covered by the GNU General Public License. It was originally written by Linus Torvalds with help of a group of hackers around the net. It is currently maintained by Junio C Hamano. Please read the file INSTALL for installation instructions. See Documentation/tutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and "man git-commandname" for documentation of each command. CVS users may also want to read Documentation/cvs-migration.txt. Many Git online resources are accessible from http://git.or.cz/ including full documentation and Git related tools. The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org. To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at http://marc.theaimsgroup.com/?l=git and other archival sites. The messages titled "A note from the maintainer", "What's in git.git (stable)" and "What's cooking in git.git (topics)" and the discussion following them on the mailing list give a good reference for project status, development direction and remaining tasks.
