2009-02-10Generalize and libify index_is_dirty() to index_differs_from(...)Libravatar Stephan Beyer1-12/+1
index_is_dirty() in builtin-revert.c checks if the index is dirty. This patch generalizes this function to check if the index differs from a revision, i.e. the former index_is_dirty() behavior can now be achieved by index_differs_from("HEAD", 0). The second argument "diff_flags" allows to set further diff option flags like DIFF_OPT_IGNORE_SUBMODULES. See DIFF_OPT_* macros in diff.h for a list. index_differs_from() seems to be useful for more than builtin-revert.c, so it is moved into diff-lib.c and also used in builtin-commit.c. Yet to mention: - "rev.abbrev = 0;" can be safely removed. This has no impact on performance or functioning of neither setup_revisions() nor run_diff_index(). - rev.pending.objects is free()d because this fixes a leak.

2008-12-21git-revert: record the parent against which a revert was madeLibravatar Robin Rosenberg1-0/+5
As described in Documentation/howto/revert-a-faulty-merge.txt, re-merging from a previously reverted a merge of a side branch may need a revert of the revert beforehand. Record against which parent the revert was made in the commit, so that later the user can figure out what went on.

When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version.

2008-03-02revert: actually check for a dirty indexLibravatar Jeff King1-4/+16
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. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-02-22Avoid unnecessary "if-before-free" tests.Libravatar Jim Meyering1-2/+1
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*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\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>.

2008-02-05Make error messages from cherry-pick/revert more sensibleLibravatar Junio C Hamano1-2/+3
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).

2007-11-30revert/cherry-pick: Allow overriding the help text by the calling PorcelainLibravatar Wincent Colaiuta1-10/+23
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.

2007-11-25revert/cherry-pick: do not mention the original refLibravatar Junio C Hamano1-13/+1
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>

There is no reason to forbid a dirty work tree when reverting or cherry-picking a change, as long as the index is clean.

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.

2007-05-23Fix command line parameter parser of revert/cherry-pickLibravatar Junio C Hamano1-2/+5

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.

2007-03-05cherry-pick: Bug fix 'cherry picked from' message.Libravatar Shawn O. Pearce1-2/+2
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.
