Objects that have delta "children" from pack data reuse must consider the depth of their deepest child when they try to deltify themselves for those children not to become too deep. However, in the context of a "thin" pack, the delta children depth was skipped entirely on the presumption that the pack was always going to be exploded on the receiving end, hence the delta length wasn't an issue. Now that we keep received packs as is and reuse pack data when repacking, those packs do contain delta chains that are longer than expected. Worse, those delta chain may even grow longer when the pack is further repacked into another thin pack for a subsequent transmission. So this patch restores strict delta length even for thin packs, and it moves check_delta_limit() usage directly in the delta loop where it is needed. This way the delta_limit can be removed from struct object_entry as well. Oh and the initial value was wrong too. The progress_interval() function was moved to a more logical location in the process.

//////////////////////////////////////////////////////////////// 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.
