* Merge branch 'nd/misc-cleanups'Junio C Hamano2011-12-052-6/+7
|\ | | | | | | | | | | | | | | | | | | * nd/misc-cleanups: unpack_object_header_buffer(): clear the size field upon error tree_entry_interesting: make use of local pointer "item" tree_entry_interesting(): give meaningful names to return values read_directory_recursive: reduce one indentation level get_tree_entry(): do not call find_tree_entry() on an empty tree tree-walk.c: do not leak internal structure in tree_entry_len()
| * tree_entry_interesting(): give meaningful names to return valuesNguyễn Thái Ngọc Duy2011-10-271-4/+5
| | | | | | | | | | | | | | | | | | It is a basic code hygiene to avoid magic constants that are unnamed. Besides, this helps extending the value later on for "interesting, but cannot decide if the entry truely matches yet" (ie. prefix matches) Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * tree-walk.c: do not leak internal structure in tree_entry_len()Nguyễn Thái Ngọc Duy2011-10-272-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | tree_entry_len() does not simply take two random arguments and return a tree length. The two pointers must point to a tree item structure, or struct name_entry. Passing random pointers will return incorrect value. Force callers to pass struct name_entry instead of two pointers (with hope that they don't manually construct struct name_entry themselves) Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | | | builtin-branch: Fix crash on invalid use of --forceVincent van Ravesteijn2011-11-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The option --force should not put us in 'create branch' mode. The fact that this option is only valid in 'create branch' mode is already caught by the the next 'if' in which we assure that we are in the correct mode. Without this patch, "git branch -f" without any other argument ends up calling create_branch without any branch name.

* | | | revert --abort: do not leave behind useless sequencer-old directoryJonathan Nieder2011-11-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "git cherry-pick --abort" command currently renames the .git/sequencer directory to .git/sequencer-old instead of removing it on success due to an accident. cherry-pick --abort is designed to work in three steps: 1) find which commit to roll back to 2) call "git reset --merge <commit>" to move to that commit 3) remove the .git/sequencer directory But the careless author forgot step 3 entirely. The only reason the command worked anyway is that "git reset --merge <commit>" renames the .git/sequencer directory as a secondary effect --- after moving to <commit>, or so the logic goes, it is unlikely but possible that the caller of git reset wants to continue the series of cherry-picks that was in progress, so git renames the sequencer state to .git/sequencer-old to be helpful while allowing the cherry-pick to be resumed if the caller did not want to end the sequence after all. By running "git cherry-pick --abort", the operator has clearly indicated that she is not planning to continue cherry-picking. Remove the (renamed) .git/sequencer directory as intended all along.

* | | | revert: introduce --abort to cancel a failed cherry-pickJonathan Nieder2011-11-221-3/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After running some ill-advised command like "git cherry-pick HEAD..linux-next", the bewildered novice may want to return to more familiar territory. Introduce a "git cherry-pick --abort" command that rolls back the entire cherry-pick sequence and places the repository back on solid ground. Just like "git merge --abort", this internally uses "git reset --merge", so local changes not involved in the conflict resolution are preserved.

For example, to produce a copy of the patch to refer to while resolving conflicts: $ git revert 2eceb2a8 error: could not revert 2eceb2a8... awesome, buggy feature $ git show -R REVERT_HEAD >the-patch $ edit $(git diff --name-only) Set a REVERT_HEAD pseudoref when "git revert" does not make a commit, for cases like this. This also makes it possible for scripts to distinguish between a revert that encountered conflicts and other sources of an unmerged index. After successfully committing, resetting with "git reset", or moving to another commit with "git checkout" or "git reset", the pseudoref is no longer useful, so remove it.

* | | | revert: improve error message for cherry-pick during cherry-pickJonathan Nieder2011-11-221-7/+6

However, the error message on attempting step 3 is more convoluted than necessary: $ git cherry-pick HEAD..origin error: .git/sequencer already exists. error: A cherry-pick or revert is in progress. hint: Use --continue to continue the operation hint: or --quit to forget about it fatal: cherry-pick failed Clarify by removing the redundant first "error:" message, simplifying the advice, and using lower-case and no full stops to be consistent with other commands that prefix their messages with "error:", so it becomes error: a cherry-pick or revert is already in progress hint: try "git cherry-pick (--continue | --quit)" fatal: cherry-pick failed The "fatal: cherry-pick failed" line seems unnecessary, too, but that can be fixed some other day.

Change it now, while we still have the time. The new name for "cherry-pick, please get out of my way, since I've long forgotten about the sequence of commits I was cherry-picking when you wrote that old .git/sequencer directory" is --quit. Mnemonic: this is analagous to quiting a program the user is no longer using --- we just want to get out of the multiple-command cherry-pick procedure and not to reset HEAD or rewind any other old state. The "--reset" option is kept as a synonym to minimize the impact. We might consider dropping it for simplicity in a separate patch, though. Adjust documentation and tests to use the newly preferred name (--quit) instead of --reset. While at it, let's clarify the short descriptions of these operations in "-h" output. Before: --reset forget the current operation --continue continue the current operation After: --quit end revert or cherry-pick sequence --continue resume revert or cherry-pick sequence Noticed-by: Phil Hord <phil.hord@gmail.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The *.doc file is converted to plain text by antiword via the textconv mechanism. However, the plain text returned by antiword contains DOS line endings instead of Unix line endings which triggered the strbuf_setlen() which previous to this patch failed.

We were doing extreme amounts of object re-traversal: for the 2.14 million objects in the Linux kernel repository, we were calling add_to_write_order() over 1.03 billion times (a 0.2% hit rate, making 99.8% of of these calls extraneous). Two optimizations take place here- we can start our objects array iteration from a known point where we left off before we started trying to find our tags, and we don't need to do the deep dives required by add_family_to_write_order() if the object has already been marked as filled. These two optimizations bring some pretty spectacular results via `perf stat`: task-clock: 83373 ms --> 43800 ms (50% faster) cycles: 221,633,461,676 --> 116,307,209,986 (47% fewer) instructions: 149,299,179,939 --> 122,998,800,184 (18% fewer) Helped-by: Ramsay Jones (format string fix in "die" message) Signed-off-by: Dan McGee <dpmcgee@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This is hitting the point where micro-optimizations do make a difference, and inlining it only increases the object file size by 38 bytes. As reported by perf, this dropped task-clock from 84183 to 83373 ms, and total cycles from 223.5 billion to 221.6 billion. Not astronomical, but worth getting for adding one word.

Now, when we're not running in a threaded manner, the mutex is not initialized, which is correct. But then we went and used the mutex anyway, which -- at least on Windows -- leads to a hard crash (ordinarily it would be called a segmentation fault, but in Windows speak it is an access violation). This problem was identified by our faithful tests when run in the msysGit environment. To avoid having to wrap the line due to the 80 column limit, we use the name "WHEN_THREADED" instead of "IF_USE_THREADS" because it is one character shorter. Which is all we need in this case.
