2011-12-06Refactor cache_tree_update idiom from commitThomas Rast
We'll need to safely create or update the cache-tree data of the_index from other places. While at it, give it an argument that lets us silence the messages produced by unmerged entries (which prevent it from working).

2011-12-06Test the current state of the cache-tree optimizationThomas Rast
The cache-tree optimization originally helped speed up write-tree operation. However, many commands no longer properly maintain -- or use an opportunity to cheaply generate -- the cache-tree data. In particular, this affects commit, checkout and reset. The notable examples that *do* write cache-tree data are read-tree and write-tree. This sadly means most people no longer benefit from the optimization, as they would not normally use the plumbing commands. Document the current state of affairs in a test file, in preparation for improvements in the area. Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-11-23builtin-branch: Fix crash on invalid use of --forceVincent van Ravesteijn
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.

2011-11-23revert --abort: do not leave behind useless sequencer-old directoryJonathan Nieder
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.

On Windows, it is not possible to rename or remove a directory that has open files. 'revert --abort' renamed .git/sequencer when it still had .git/sequencer/head open.

2011-11-23revert: introduce --abort to cancel a failed cherry-pickJonathan Nieder
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.

2011-11-22revert: write REVERT_HEAD pseudoref during conflicted revertJonathan Nieder
When conflicts are encountered while reverting a commit, it can be handy to have the name of that commit easily available. 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.

2011-11-22revert: improve error message for cherry-pick during cherry-pickJonathan Nieder
In the spirit of v1.6.3.3~3^2 (refuse to merge during a merge, 2009-07-01), "git cherry-pick" refuses to start a new cherry-pick when in the middle of an existing conflicted cherry-pick in the following sequence: 1. git cherry-pick HEAD..origin 2. resolve conflicts 3. git cherry-pick HEAD..origin (instead of "git cherry-pick --continue", by mistake) Good. 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.

2011-11-22revert: rearrange pick_revisions() for clarityJonathan Nieder
Deal completely with "cherry-pick --quit" and --continue at the beginning of pick_revisions(), leaving the rest of the function for the more interesting "git cherry-pick <commits>" case.

2011-11-22revert: rename --reset option to --quitJonathan Nieder
The option to "git cherry-pick" and "git revert" to discard the sequencer state introduced by v1.7.8-rc0~141^2~6 (revert: Introduce --reset to remove sequencer state, 2011-08-04) has a confusing name. 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>

2011-11-21config.c: Fix a static buffer overwrite bug by avoiding mkpath()Ramsay Jones
On cygwin, test number 21 of t3200-branch.sh (git branch -m q q2 without config should succeed) fails. The failure involves the functions from path.c which parcel out internal static buffers from the git_path() and mkpath() functions. In particular, the rename_ref() function calls safe_create_leading\ _directories() with a filename returned by git_path("logs/%s", ref). safe_create_leading_directories(), in turn, calls stat() on each element of the path it is given. On cygwin, this leads to a call to git_config() for each component of the path, since this test explicitly removes the config file. git_config() calls mkpath(), so on the fourth component of the path, the original buffer passed into the function is overwritten with the config filename. Note that this bug is specific to cygwin and it's schizophrenic stat() functions (see commits adbc0b6, 7faee6b and 7974843). The lack of a config file and a path with at least four elements is also important to trigger the bug. In order to fix the problem, we replace the call to mkpath() with a call to mksnpath() and provide our own buffer.

2011-11-21t5501-*.sh: Fix url passed to clone in setup testRamsay Jones
In particular, the url passed to git-clone has an extra '/' given after the 'file://' schema prefix, thus: git clone --reference=original "file:///$(pwd)/original one Once the prefix is removed, the remainder of the url looks something like "//home/ramsay/git/t/...", which is then interpreted as an network path. This then results in a "Permission denied" error, like so: ramsay $ ls //home ls: cannot access //home: No such host or network path ramsay $ ls //home/ramsay ls: cannot access //home/ramsay: Permission denied ramsay $ In order to fix the problem, we simply remove the extraneous '/' character from the url.

2011-11-18Makefile: add option to disable automatic dependency generationJonathan Nieder
Now that the COMPUTE_HEADER_DEPENDENCIES feature is turned on automatically for compilers that support it (see v1.7.8-rc0~142^2~1, 2011-08-18), there is no easy way to force it off. For example, setting COMPUTE_HEADER_DEPENDENCIES to the empty string in config.mak just tells the makefile to treat it as undefined and run a test command to see if the -MMD option is supported. So allow setting COMPUTE_HEADER_DEPENDENCIES=no to explicitly force the feature off. The new semantics: - "yes" means to explicitly enable the feature - "no" means to disable it - "auto" means to autodetect The default is still "auto". Any value other than these three will cause the build to error out with a descriptive message so typos and stale settings in config.mak don't result in mysterious behavior. Makefile:1278: *** please set COMPUTE_HEADER_DEPENDENCIES to yes, no, or auto (not "1"). Stop. So now when someone using a compiler without -MMD support reports trouble building git, you can reproduce it by running "make COMPUTE_HEADER_DEPENDENCIES=no".

2011-11-18notes merge: eliminate OUTPUT macroJonathan Nieder
The macro is variadic, which breaks support for pre-C99 compilers, and it hides an "if", which can make code hard to understand on first reading if some arguments have side-effects. The OUTPUT macro seems to have been inspired by the "output" function from merge-recursive. But that function in merge-recursive exists to indent output based on the level of recursion and there is no similar justification for such a function in "notes merge".

2011-11-17do not let git_path clobber errno when reporting errorsJonathan Nieder
Because git_path() calls vsnprintf(), code like fd = open(git_path("SQUASH_MSG"), O_WRONLY | O_CREAT, 0666); die_errno(_("Could not write to '%s'"), git_path("SQUASH_MSG")); can end up printing an error indicator from vsnprintf() instead of open() by mistake. Store the path we are trying to write to in a temporary variable and pass _that_ to die_errno(), so the messages written by git cherry-pick/revert and git merge can avoid this source of confusion.

2011-11-17refs: loosen over-strict "format" checkJunio C Hamano
The add_extra_ref() interface is used to add an extra-ref that is _not_ our ref for the purpose of helping auto-following of tags and reducing object transfer from remote repository, and they are typically formatted as a tagname followed by ^{} to make sure no valid refs match that pattern. In other words, these entries are deliberately formatted not to pass check-refname-format test. A recent series however added a test unconditionally to the add_ref() function that is called from add_extra_ref(). The check may be sensible for other two callsites of the add_ref() interface, but definitely is a wrong thing to do in add_extra_ref(). Disable it.

Some of the fatal messages printed by revert and cherry-pick look ugly like the following: fatal: Could not open .git/sequencer/todo.: No such file or directory The culprit here is that these callers of the die_errno() function did not take it into account that the message string they give to it is followed by ": <strerror>", hence the message typically should not end with the full-stop.
