Jeff King	0f2d4476c1	revert: actually check for a dirty index The previous code mistakenly used wt_status_prepare to check whether the index had anything commitable in it; however, that function is just an init function, and will never report a dirty index. The correct way with wt_status_* would be to call wt_status_print with the output pointing to /dev/null or similar. However, that does extra work by both examining the working tree and spewing status information to nowhere. Instead, let's just implement the useful subset of wt_status_print as an "is_index_dirty" function.

Jim Meyering	8e0f70033b	Avoid unnecessary "if-before-free" tests. This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z \| xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s$\s(\S+?)(?:\s!=\sNULL)?\s$\s+(free\s$\s\1\s$)/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it does detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

Junio C Hamano	45525bd022	Make error messages from cherry-pick/revert more sensible The original "rewrite in C" did somewhat a sloppy job while stealing code from git-write-tree. The caller pretends as if the write_tree() function would return an error code and being able to issue a sensible error message itself, but write_tree() function just calls die() and never returns an error. Worse yet, the function claims that it was running git-write-tree (which is no longer true after cherry-pick stole it).

David Symonds	0d8135891e	Mention that git-rm can be an appropriate resolution as well as git-add. Especially when using git-cherry-pick, removing files that are unmerged can be a logical action.

Wincent Colaiuta	804c7174c9	revert/cherry-pick: Allow overriding the help text by the calling Porcelain A Porcelain command that uses cherry-pick or revert may make a commit out of resolved index itself, in which case telling the user to commit the result is not appropriate at all. This allows GIT_CHERRY_PICK_HELP environment variable to be set by the calling Porcelain in order to override the built-in help text. [jc: this is heavily modified from the original but should be equivalent in spirit] Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Junio C Hamano	757f58ed38	revert/cherry-pick: do not mention the original ref When you cherry-pick or revert a commit, naming it with an annotated tag, we added a comment, attempting to repeat what we got from the end user, to the message. But this was inconsistent. When we got "cherry-pick branch", we recorded the object name (40-letter SHA-1) without saying anything like "original was 'branch'". There was no need to. Also recent rewrite to use parse-options made it impossible to parrot the original command line without "unparsing". This removes the code that implements the misguided "we dereferenced the tag so record that in the commit message" behaviour. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Junio C Hamano	71aa2b8f0e	Resurrect git-revert.sh example and add comment to builtin-revert.c I had to scratch my head for quite some time figuring out why we cannot optimize out write_tree() we do when --no-commit option is given, whose purpose seem to be only to check if the index is unmerged, with a simple loop over the active_cache[]. So add a comment to describe why the write_tree() is there, and resurrect the last scripted version as a reference material in contrib/example directory with others.

Junio C Hamano	245de36f03	revert/cherry-pick: allow starting from dirty work tree. There is no reason to forbid a dirty work tree when reverting or cherry-picking a change, as long as the index is clean. The scripted version used to allow it: case "$no_commit" in t) # We do not intend to commit immediately. We just want to # merge the differences in. head=$(git-write-tree) \|\| die "Your index file is unmerged." ;; *) head=$(git-rev-parse --verify HEAD) \|\| die "You do not have a valid HEAD" files=$(git-diff-index --cached --name-only $head) \|\| exit if [ "$files" ]; then die "Dirty index: cannot $me (dirty: $files)" fi ;; esac but C rewrite tightened the check, probably by mistake.

Nicolas Pitre	04bd8e5fea	cherry-pick/revert: more compact user direction message A failed cherry-pick (and friend) currently says: \|Automatic cherry-pick failed.

Junio C Hamano	7791ecbc62	revert/cherry-pick: work on merge commits as well Usually you cannot revert a merge because you do not know which side of the merge should be considered the mainline (iow, what change to reverse). With this patch, cherry-pick and revert learn -m (--mainline) option that lets you specify the parent number (starting from 1) of the mainline, so that you can: git revert -m 1 $merge to reverse the changes introduced by the $merge commit relative to its first parent, and: git cherry-pick -m 2 $merge to replay the changes introduced by the $merge commit relative to its second parent.

Junio C Hamano	32309f54ed	Fix command line parameter parser of revert/cherry-pick The parser was inconsistently done, in that it did not look at the last command line parameter to see if it could be an unknown option, although it was designed to notice unknown options if they were given in positions the command expects to find them (i.e. everything except the last parameter, which ought to be <commit-ish>). This prevented a very natural invocation $ git cherry-pick --usage from issuing the usage help. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Shawn O. Pearce	abda522777	Use .git/MERGE_MSG in cherry-pick/revert Rather than storing the temporary commit message data in .msg (in the working tree) we now store the message data in .git/MERGE_MSG. By storing the message in the .git/ directory we are sure we will never have a collision with a user file, should a project actually have a ".msg" file in their top level tree. We also don't need to worry about leaving this stale file behind during a `reset --hard` and have it show up in the output of status. We are using .git/MERGE_MSG here to store the temporary message as it is an already established convention between git-merge, git-am and git-rebase that git-commit will default the user's edit buffer to the contents of .git/MERGE_MSG. If the user is going to need to resolve this commit or wants to edit the message on their own prepping that file with the desired message "just works". Signed-off-by: Shawn O.

Johannes Schindelin	e43b010582	git-revert: Revert revert message to old behaviour When converting from the shell script, based on a misreading of the sed invocation, the builtin included the abbreviated commit name, and did _not_ include the quotes around the oneline message.

Shawn O. Pearce	0e6240447c	cherry-pick: Bug fix 'cherry picked from' message. Somewhere along the line (in `abd6970a`) git-revert.sh learned to omit the private object name from the new commit message unless -x was supplied on the command line by the user. The way this was implemented is really non-obvious in the original script. Setting replay=t (the default) means we don't include the the private object name, while setting reply='' (the -x flag) means we should include the private object name. These two settings now relate to the replay=1 and replay=0 cases in the C version, so we need to negate replay to test it is 0. I also noticed the C version was adding an extra LF in the -x case, where the older git-revert.sh was not. Signed-off-by: Shawn O.

Johannes Schindelin	f52463a582	cherry-pick: Suggest a better method to retain authorship When a cherry-pick failed, we used to recommend setting environment variables to retain the authorship. It is much easier, though, to use the "-c" flag of git-commit. Print this message also when merge-recursive fails (the code used to exit(1) in that case, never reaching the proper failure path).
