This is to let the system know that you will tell it the final contents to be staged later, iow, just be aware of the presense of the path with the type of the blob for now. It is implemented by staging an empty blob as the content. With this sequence: $ git reset --hard $ edit newfile $ git add -N newfile $ edit newfile oldfile $ git diff the diff will show all changes relative to the current commit. Then you can do: $ git commit -a ;# commit everything or $ git commit oldfile ;# only oldfile, newfile not yet added to pretend you are working with an index-free system like CVS.

Compilation of git is probably broken on PPC too for the same reason. Turns out that the only file requiring openssl/ssl.h and openssl/err.h is imap-send.c. But only moving those problematic includes there doesn't solve the issue as it also includes cache.h which brings in the conflicting local SHA1 header file. As suggested by Jeff King, the best solution is to rename our references to SHA1 functions and structure to something git specific, and define those according to the implementation used.

* | push: receiver end advertises refs from alternate repositoriesJunio C Hamano2008-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, when pushing into a repository that borrows from alternate object stores, we followed the longstanding design decision not to trust refs in the alternate repository that houses the object store we are borrowing from. If your public repository is borrowing from Linus's public repository, you pushed into it long time ago, and now when you try to push your updated history that is in sync with more recent history from Linus, you will end up sending not just your own development, but also the changes you acquired through Linus's tree, even though the objects needed for the latter already exists at the receiving end. This is because the receiving end does not advertise that the objects only reachable from the borrowed repository (i.e. Linus's) are already available there. This solves the issue by making the receiving end advertise refs from borrowed repositories. They are not sent with their true names but with a phoney name ".have" to make sure that the old senders will safely ignore them (otherwise, the old senders will misbehave, trying to push matching refs, and mirror push that deletes refs that only exist at the receiving end).

* | push: prepare sender to receive extended ref information from the receiverJunio C Hamano2008-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "git push" enhancement allows the receiving end to report not only its own refs but refs in repositories it borrows from via the alternate object store mechanism. By telling the sender that objects reachable from these extra refs are already complete in the receiving end, the number of objects that need to be transfered can be cut down. These entries are sent over the wire with string ".have", instead of the actual names of the refs. This string was chosen so that they are ignored by older programs at the sending end. If we sent some random but valid looking refnames for these entries, "matching refs" rule (triggered when running "git push" without explicit refspecs, where the sender learns what refs the receiver has, and updates only the ones with the names of the refs the sender also has) and "delete missing" rule (triggered when "git push --mirror" is used, where the sender tells the receiver to delete the refs it itself does not have) would try to update/delete them, which is not what we want. This prepares the send-pack (and "push" that runs native protocol) to accept extended existing ref information and make use of it. The ".have" entries are excluded from ref matching rules, and are exempt from deletion rule while pushing with --mirror option, but are still used for pack generation purposes by providing more "bottom" range commits.

| * | unpack_trees(): protect the handcrafted in-core index from read_cache()Junio C Hamano2008-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unpack_trees() rebuilds the in-core index from scratch by allocating a new structure and finishing it off by copying the built one to the final index. The resulting in-core index is Ok for most use, but read_cache() does not recognize it as such. The function is meant to be no-op if you already have loaded the index, until you call discard_cache(). This change the way read_cache() detects an already initialized in-core index, by introducing an extra bit, and marks the handcrafted in-core index as initialized, to avoid this problem. A better fix in the longer term would be to change the read_cache() API so that it will always discard and re-read from the on-disk index to avoid confusion. But there are higher level API that have relied on the current semantics, and they and their users all need to get converted, which is outside the scope of 'maint' track. An example of such a higher level API is write_cache_as_tree(), which is used by git-write-tree as well as later Porcelains like git-merge, revert and cherry-pick. In the longer term, we should remove read_cache() from there and add one to cmd_write_tree(); other callers expect that the in-core index they prepared is what gets written as a tree so no other change is necessary for this particular codepath. The original version of this patch marked the index by pointing an otherwise wasted malloc'ed memory with o->result.alloc, but this version uses Linus's idea to use a new "initialized" bit, which is conceptually much cleaner.

* | git-mv: Keep moved index entries inactPetr Baudis2008-07-27
|/ | | | | | | | | | | | | | | | | | | | | | | | The rewrite of git-mv from a shell script to a builtin was perhaps a little too straightforward: the git add and git rm queues were emulated directly, which resulted in a rather complicated code and caused an inconsistent behaviour when moving dirty index entries; git mv would update the entry based on working tree state, except in case of overwrites, where the new entry would still have sha1 of the old file. This patch introduces rename_index_entry_at() into the index toolkit, which will rename an entry while removing any entries the new entry might render duplicate. This is then used in git mv instead of all the file queues, resulting in a major simplification of the code and an inevitable change in git mv -n output format. Also the code used to refuse renaming overwriting symlink with a regular file and vice versa; there is no need for that. A few new tests have been added to the testsuite to reflect this change.

* "needs update" considered harmfulJunio C Hamano2008-07-20
| | | | | | | | | | | | | | | | | | | | | | "git update-index --refresh", "git reset" and "git add --refresh" have reported paths that have local modifications as "needs update" since the beginning of git. Although this is logically correct in that you need to update the index at that path before you can commit that change, it is now becoming more and more clear, especially with the continuous push for user friendliness since 1.5.0 series, that the message is suboptimal. After all, the change may be something the user might want to get rid of, and "updating" would be absolutely a wrong thing to do if that is the case. I prepared two alternatives to solve this. Both aim to reword the message to more neutral "locally modified". This patch is a more intrusive variant that changes the message for only Porcelain commands ("add" and "reset") while keeping the plumbing "update-index" intact.

| * clone: create intermediate directories of destination repoJeff King2008-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The shell version used to use "mkdir -p" to create the repo path, but the C version just calls "mkdir". Let's replicate the old behavior. We have to create the git and worktree leading dirs separately; while most of the time, the worktree dir contains the git dir (as .git), the user can override this using GIT_WORK_TREE. We can reuse safe_create_leading_directories, but we need to make a copy of our const buffer to do so. Since merge-recursive uses the same pattern, we can factor this out into a global function. This has two other cleanup advantages for merge-recursive: 1. mkdir_p wasn't a very good name. "mkdir -p foo/bar" actually creates bar, but this function just creates the leading directories. 2. mkdir_p took a mode argument, but it was completely ignored.

We have to create the git and worktree leading dirs separately; while most of the time, the worktree dir contains the git dir (as .git), the user can override this using GIT_WORK_TREE. We can reuse safe_create_leading_directories, but we need to make a copy of our const buffer to do so. Since merge-recursive uses the same pattern, we can factor this out into a global function. This has two other cleanup advantages for merge-recursive: 1. mkdir_p wasn't a very good name. "mkdir -p foo/bar" actually creates bar, but this function just creates the leading directories. 2. mkdir_p took a mode argument, but it was completely ignored.

* | | | implement some resilience against pack corruptionsNicolas Pitre2008-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should be able to fall back to loose objects or alternative packs when a pack becomes corrupted. This is especially true when an object exists in one pack only as a delta but its base object is corrupted. Currently there is no way to retrieve the former object even if the later is available in another pack or loose. This patch allows for a delta to be resolved (with a performance cost) using a base object from a source other than the pack where that delta is located. Same thing for non-delta objects: rather than failing outright, a search is made in other packs or used loose when the currently active pack has it but corrupted. Of course git will become extremely noisy with error messages when that happens. However, if the operation succeeds nevertheless, a simple 'git repack -a -f -d' will "fix" the corrupted repository given that all corrupted objects have a good duplicate somewhere in the object store, possibly manually copied from another source.

* | | Make git_dir a path relative to work_tree in setup_work_tree()Linus Torvalds2008-06-19

This should save the kernel some time traversing the path to work_tree all the time if git_dir is inside work_tree. Daniel's patch didn't apply for me as-is, so I recreated it with some differences, and here are the numbers from ten runs each. There is some IO for me - probably due to more-or-less random flushing of the journal - so the variation is bigger than I'd like, but whatever: Before: real 0m8.135s real 0m7.933s real 0m8.080s real 0m7.954s real 0m7.949s real 0m8.112s real 0m7.934s real 0m8.059s real 0m7.979s real 0m8.038s After: real 0m7.685s real 0m7.968s real 0m7.703s real 0m7.850s real 0m7.995s real 0m7.817s real 0m7.963s real 0m7.955s real 0m7.848s real 0m7.969s Now, going by "best of ten" (on the assumption that the longer numbers are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does seem to be outside of the noise (ie the "after" case never broke 8s, while the "before" case did so half the time). So looks like about 3% to me. Doing it for a slightly smaller test-case (just the "arch" subdirectory) gets more stable numbers probably due to not filling the journal with metadata updates, so we have: Before: real 0m1.633s real 0m1.633s real 0m1.633s real 0m1.632s real 0m1.632s real 0m1.630s real 0m1.634s real 0m1.631s real 0m1.632s real 0m1.632s After: real 0m1.610s real 0m1.609s real 0m1.610s real 0m1.608s real 0m1.607s real 0m1.610s real 0m1.609s real 0m1.611s real 0m1.608s real 0m1.611s where I'ld just take the averages and say 1.632 vs 1.610, which is just over 1% peformance improvement. So it's not in the noise, but it's not as big as I initially thought and measured. (That said, it obviously depends on how deep the working directory path is too, and whether it is behind NFS or something else that might need to cause more work to look up).
