2010-08-15cherry-pick/revert: Use advise() for hintsLibravatar Jonathan Nieder1-23/+11
When cherry-pick fails after picking a large series of commits, it can be hard to pick out the error message and advice. Prefix the advice with “hint: ” to help. Before: error: could not apply 7ab78c9... foo After resolving the conflicts, mark the corrected paths with 'git add <paths>' or 'git rm <paths>' and commit the result with: git commit -c 7ab78c9a7898b87127365478431289cb98f8d98f After: error: could not apply 7ab78c9... foo hint: after resolving the conflicts, mark the corrected paths hint: with 'git add <paths>' or 'git rm <paths>' hint: and commit the result with 'git commit -c 7ab78c9' Noticed-by: Thomas Rast <trast@student.ethz.ch> Encouraged-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Like error(), warn(), and die(), advise() prints a short message with a formulaic prefix to stderr. It is local to revert.c for now because I am not sure this is the right API (we may want to take an array of advice lines or a boolean argument for easy suppression of unwanted advice).

2010-08-15Eliminate “Finished cherry-pick/revert” messageLibravatar Jonathan Nieder1-2/+0
When cherry-pick was written (v0.99.6~63, 2005-08-27), “git commit” was quiet, and the output from cherry-pick provided useful information about the progress of a rebase. Now next to the output from “git commit”, the cherry-pick notification is so much noise (except for the name of the picked commit). $ git cherry-pick ..topic Finished cherry-pick of 499088b. [detached HEAD 17e1ff2] Move glob module to libdpkg Author: Guillem Jover <guillem@debian.org> 8 files changed, 12 insertions(+), 9 deletions(-) rename {src => lib/dpkg}/glob.c (98%) rename {src => lib/dpkg}/glob.h (93%) Finished cherry-pick of ae947e1.

2010-08-06merge-recursive --renormalizeLibravatar Jonathan Nieder1-0/+7
Teach "git merge-recursive" a --renormalize option to enable the merge.renormalize configuration. The --no-renormalize option can be used to override it in the negative. So in the future, you might be able to, e.g.: git checkout -m -Xrenormalize otherbranch or git revert -Xrenormalize otherpatch or git pull --rebase -Xrenormalize The bad part: merge.renormalize is still not honored for most commands. And it reveals lots of places that -X has not been plumbed in (so we get "git merge -Xrenormalize" but not much else).

2010-07-16revert: improve success message by adding abbreviated commit sha1Libravatar Christian Couder1-2/+3
Instead of saying "Finished one cherry-pick." or "Finished one revert.", we now say "Finished cherry-pick of commit <abbreviated sha1>." or "Finished revert of commit <abbreviated sha1>." which is more informative, especially when cherry-picking or reverting many commits. In case of failure the message is now "Automatic cherry-pick of commit <abbreviated sha1> failed." instead of "Automatic cherry-pick failed."

2010-07-16revert: report success when using option --strategyLibravatar Christian Couder1-22/+29
"git cherry-pick foo" has always reported success with "Finished one cherry-pick" but "cherry-pick --strategy" does not print anything. So move the code to write that message from do_recursive_merge() to do_cherry_pick() so other strategies can share it. This patch also refactors the code that prints a message like "Automatic cherry-pick failed. <help message>". This code was duplicated in both do_recursive_merge() and do_pick_commit(). To do that, now do_recursive_merge() returns an int to signal success or failure. And in case of failure we just return 1 from do_pick_commit() instead of doing "exit(1)" from either do_recursive_merge() or do_pick_commit().

2010-06-02revert: allow cherry-picking more than one commitLibravatar Christian Couder1-10/+41
This makes it possible to pass many commits or ranges of commits to "git cherry-pick" and to "git revert" to process many commits instead of just one. In fact commits are now enumerated with an equivalent of git rev-list --no-walk "$@" so all the following are now possible: git cherry-pick master~2..master git cherry-pick ^master~2 master git cherry-pick master^ master The following should be possible but does not work: git cherry-pick -2 master because "git rev-list --no-walk -2 master" only outputs one commit as "--no-walk" seems to take over "-2". And there is currently no way to continue cherry-picking or reverting if there is a problem with one commit. It's also not possible to abort the whole process. Some future work should provide the --continue and --abort options to do just that. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-05-08cherry-pick: do not dump core when iconv failsLibravatar Jonathan Nieder1-2/+7
When cherry-picking, usually the new and old commit encodings are both UTF-8. Most old iconv implementations do not support this trivial conversion, so on old platforms, out->message remains NULL, and later attempts to read it segfault. Fix this by noticing the input and output encodings match and skipping the iconv step, like the other reencode_string() call sites already do. Also stop segfaulting on other iconv failures: if iconv fails for some other reason, the best we can do is to pass the old message through. This fixes a regression introduced in v1.7.1-rc0~15^2~2 (revert: clarify label on conflict hunks, 2010-03-20).

2010-03-20cherry-pick, revert: add a label for ancestorLibravatar Jonathan Nieder1-1/+4
When writing conflict hunks in ‘diff3 -m’ format, also add a label to the common ancestor. Especially in a cherry-pick, it is not immediately obvious without such a label what the common ancestor represents. git rerere does not have trouble parsing the new output and its preimage ids are unchanged since it includes its own code for recreating conflict hunks. No other code in git parses conflict hunks.

2010-03-20revert: clarify label on conflict hunksLibravatar Jonathan Nieder1-39/+62
When reverting a commit, the commit being merged is not the commit to revert itself but its parent. Add “parent of” to the conflict hunk label to make this more clear. The conflict hunk labels are all pieces of a single string written in the new get_message() function. Avoid some complication by using mempcpy to advance a pointer as the result is written. Also free the corresponding temporary buffer (it was leaked before). This is not important because it is a small one-time allocation. It would become a memory leak if unnoticed when libifying revert. This patch uses calls to strlen() instead of integer constants in some places. GCC will compute the length at compile time; I am not sure about other compilers, but this is not performance-critical anyway.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLibravatar Linus Torvalds1-0/+460
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities?

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
