When it is not necessary to edit a commit log message (e.g. "git commit -m" is given a message without specifying "-e"), we used to disable the spawning of the editor by overriding GIT_EDITOR, but this means all the uses of the editor, other than to edit the commit log message, are also affected. * bp/commit-p-editor: run-command: mark run_hook_with_custom_index as deprecated merge hook tests: fix and update tests merge: fix GIT_EDITOR override for commit hook commit: fix patch hunk editing with "commit -p -m" test patch hunk editing with "commit -p -m" merge hook tests: use 'test_must_fail' instead of '!' merge hook tests: fix missing '&&' in test
2014-03-24parse-options: multi-word argh should use dash to separate wordsJunio C Hamano1-1/+1
"When you need to use space, use dash" is a strange way to say that you must not use a space. Because it is more common for the command line descriptions to use dashed-multi-words, you do not even want to use spaces in these places. Rephrase the documentation to avoid this strangeness. Fix a few existing multi-word argument help strings, i.e. - GPG key-ids given to -S/--gpg-sign are "key-id"; - Refs used for storing notes are "notes-ref"; and - Expiry timestamps given to --expire are "expiry-date". and update the corresponding documentation pages.

Introduce commit.gpgsign configuration variable to force every commit to be GPG signed. The variable cannot be overriden from the command line of some of the commands that create commits except for "git commit" and "git commit-tree", but I am not convinced that it is a good idea to sprinkle support for --no-gpg-sign everywhere, which in turn means that this configuration variable may not be such a good idea. * nv/commit-gpgsign-config: test the commit.gpgsign config option commit-tree: add and document --no-gpg-sign commit-tree: add the commit.gpgsign option to sign all commits

* ms/remote-tracking-branches-in-doc: Change "remote tracking" to "remote-tracking"
2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleNguyễn Thái Ngọc Duy1-1/+1
I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

2013-07-02merge: handle --ff/--no-ff/--ff-only as a tri-state optionMiklos Vajna1-22/+33
These three options mean "favor fast-forwarding when possible, without creating an unnecessary merge", "never fast-forward and always create a merge commit even when the commit being merged is a strict descendant", and "we do not want to create any merge commit; update only when the merged commit is a strict descendant". They are "pick one out of these three possibilities" options, and correspond to "merge.ff" configuration that is tri-state (yes, no and only). However, the implementation did not follow the usual convention for the command line options (later one wins, and command line overrides what is in the configuration). Fix this by consolidating two variables (fast_forward_only and allow_fast_forward) used in the implementation into one enum that can take one of the three possible values.

Some users do want to write a line that begin with a pound sign, #, in their commit log message. Many tracking system recognise a token of #<bugid> form, for example.

Avoid such a line by rewrapping or indenting; and - Use --cleanup=whitespace but remove all the hint lines we add. Give them a way to set a custom comment char, e.g. $ git -c core.commentchar="%" commit so that they do not have to do either of the two workarounds.

When it added a call to run the prepare-commit-msg hook, however, it forgot to check the exit code from the hook like "git commit" does, and ended up replacing one inconsistency with another.

The credit lines "By" and "Via" to credit authors and committers for their contributions on the side branch are meant as a hint to the integrator to decide whom to mention in the log message text.

Instead of waiting until we record the parents of resulting merge, reduce redundant parents (including our HEAD) immediately after reading them. The change to t7602 illustrates the essence of the effect of this change. The octopus merge strategy used to be fed with redundant commits only to discard them as "up-to-date", but we no longer feed such redundant commits to it and the affected test degenerates to a regular two-head merge.

For the graph-width limiting to be usable, it should happen 'automatically' once configured, hence the config option. Nevertheless, graph width limiting only makes sense when used on a wide terminal, so it should not influence the output of format-patch, which adheres to the 80-column standard.

"The same device" test was done by comparing fstat(2) result on the two file descriptors (and they must match), and we asked isatty() only for the standard input (we insist that they are the same device and there is no point asking tty-ness of the standard output). The stat(2) emulation in the Windows port however does not give a usable value in the st_ino field, so even if the standard output is connected to something different from the standard input, "The same device" test may incorrectly return true. To accomodate it, add another isatty() check for the standard output stream as well. Reported-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-02-05merge: do not create a signed tag merge under --ff-only optionJunio C Hamano1-1/+2
Starting at release v1.7.9, if you ask to merge a signed tag, "git merge" always creates a merge commit, even when the tag points at a commit that happens to be a descendant of your current commit. Unfortunately, this interacts rather badly for people who use --ff-only to make sure that their branch is free of local developments. It used to be possible to say: $ git checkout -b frotz v1.7.9~30 $ git merge --ff-only v1.7.9 and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka the commit tagged as v1.7.9), but this fails with the updated Git with: fatal: Not possible to fast-forward, aborting. because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by fast forwarding. We could teach users that now they have to do $ git merge --ff-only v1.7.9^0 but it is far more pleasant for users if we DWIMmed this ourselves. When an integrator pulls in a topic from a lieutenant via a signed tag, even when the work done by the lieutenant happens to fast-forward, the integrator wants to have a merge record, so the integrator will not be asking for --ff-only when running "git pull" in such a case. Therefore, this change should not regress the support for the use case v1.7.9 wanted to add. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-01-31merge: add instructions to the commit message when editingThomas Rast1-0/+10
Before f824628 (merge: use editor by default in interactive sessions, 2012-01-10), git-merge only started an editor if the user explicitly asked for it with --edit. Thus it seemed unlikely that the user would need extra guidance. After f824628 the _normal_ thing is to start an editor. Give at least an indication of why we are doing it. The sentence about justification is one of the few things about standard git that are not agnostic to the workflow that the user chose. However, f824628 was proposed by Linus specifically to discourage users from merging unrelated upstream progress into topic branches. So we may as well take another step in the same direction.

2012-01-23merge: use editor by default in interactive sessionsJunio C Hamano1-4/+34
Traditionally, a cleanly resolved merge was committed by "git merge" using the auto-generated merge commit log message without invoking the editor. After 5 years of use in the field, it turns out that people perform too many unjustified merges of the upstream history into their topic branches. These merges are not just useless, but they are often not explained well, and making the end result unreadable when it gets time for merging their history back to their upstream. Earlier we added the "--edit" option to the command, so that people can edit the log message to explain and justify their merge commits. Let's take it one step further and spawn the editor by default when we are in an interactive session (i.e. the standard input and the standard output are pointing at the same tty device). There may be existing scripts that leave the standard input and the standard output of the "git merge" connected to whatever environment the scripts were started, and such invocation might trigger the above "interactive session" heuristics. GIT_MERGE_AUTOEDIT environment variable can be set to "no" at the beginning of such scripts to use the historical behaviour while the script runs. Note that this backward compatibility is meant only for scripts, and we deliberately do *not* support "merge.edit = yes/no/auto" configuration option to allow people to keep the historical behaviour.

2011-12-05Copy resolve_ref() return value for longer useNguyễn Thái Ngọc Duy1-22/+40
resolve_ref() may return a pointer to a static buffer. Callers that use this value longer than a couple of statements should copy the value to avoid some hidden resolve_ref() call that may change the static buffer's value. The bug found by Tony Wang <wwwjfy@gmail.com> in builtin/merge.c demonstrates this. The first call is in cmd_merge() branch = resolve_ref("HEAD", head_sha1, 0, &flag); Then deep in lookup_commit_or_die() a few lines after, resolve_ref() may be called again and destroy "branch". lookup_commit_or_die lookup_commit_reference lookup_commit_reference_gently parse_object lookup_replace_object do_lookup_replace_object prepare_replace_object for_each_replace_ref do_for_each_ref get_loose_refs get_ref_dir get_ref_dir resolve_ref All call sites are checked and made sure that xstrdup() is called if the value should be saved.

Ignored files usually are generated files (e.g. .o files) and can be safely discarded. However sometimes users may have important files in working directory, but still want a clean "git status", so they mark them as ignored files. But in this case, these files should not be overwritten without asking first. Enable this use case with --no-overwrite-ignore, where git only sees tracked and untracked files, no ignored files. Those who mix discardable ignored files with important ones may have to sort it out themselves.

If we place it at the end of the log message, we would need to teach "git log" and friends to strip the signature block with an option. - Teaching new versions of "git log" and "gitk" to optionally verify and show signatures is cleaner if we structurally know where the signature block is (instead of scanning in the commit log message). - The signature needs to be stripped upon various commit rewriting operations, e.g. rebase, filter-branch, etc. They all already ignore unknown headers, but if we place signature in the log message, all of these tools (and third-party tools) also need to learn how a signature block would look like. - When we added the optional encoding header, all the tools (both in tree and third-party) that acts on the raw commit object should have been fixed to ignore headers they do not understand, so it is not like that new header would be more likely to break than extra text in the commit.

All of the "do we want color" flags default to -1 to indicate that we don't have any color configured. This value is handled in one of two ways: 1. In porcelain, we check early on whether the value is still -1 after reading the config, and set it to the value of color.ui (which defaults to 0). 2. In plumbing, it stays untouched as -1, and want_color defaults it to off. This works fine, but means that every porcelain has to check and reassign its color flag. Now that want_color gives us a place to put this check in a single spot, we can do that, simplifying the calling code.

This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors.

The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color".

2011-05-26clean up calling conventions for pretty.c functionsJeff King1-1/+2
We have a pretty_print_context representing the parameters for a pretty-print session, but we did not use it uniformly. As a result, functions kept growing more and more arguments. Let's clean this up in a few ways: 1. All pretty-print pp_* functions now take a context. This lets us reduce the number of arguments to these functions, since we were just passing around the context values separately. 2. The context argument now has a cmit_fmt field, which was passed around separately. That's one less argument per function. 3. The context argument always comes first, which makes calling a little more uniform. This drops lines from some callers, and adds lines in a few places (because we need an extra line to set the context's fmt field).

The merge-recursive strategy already handles root commits; it cherry-picks the difference between the empty tree and the root commit's tree. However, for external strategies, we dereference NULL and segfault while building the argument list. Instead, let's handle this by passing the empty tree sha1 to the merge script.

2011-03-25merge: merge unborn index before setting refJeff King1-1/+1
When we merge into an unborn branch, there are basically two steps: 1. Write the sha1 of the new commit into the ref pointed to by HEAD. 2. Update the index with the new content, and check it out to the working tree. We currently do them in this order. However, (2) is the step that is much more likely to fail, since it can be blocked by things like untracked working tree files. When it does, the merge fails and we are left with an empty index but an updated HEAD. This patch switches the order, so that a failure in updating the index leaves us unchanged. Of course, a failure in updating the ref now leaves us with an updated index and mis-matched HEAD. That is arguably not much better, but it is probably less likely to actually happen.

2011-02-21Introduce CHERRY_PICK_HEADJay Soffian1-0/+7
When a cherry-pick conflicts git advises: $ git commit -c <original commit id> to preserve the original commit message and authorship. Instead, let's record the original commit id in CHERRY_PICK_HEAD and advise: $ git commit -c CHERRY_PICK_HEAD A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part. Note that we record CHERRY_PICK_HEAD even in the case where there are no conflicts so that we may use it to communicate authorship to commit; this will then allow us to remove set_author_ident_env from revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit is used, as presumably the user intends to further edit the commit and possibly even cherry-pick additional commits on top.

2010-11-17Provide 'git merge --abort' as a synonym to 'git reset --merge'Johan Herland1-0/+14
Teach 'git merge' the --abort option, which verifies the existence of MERGE_HEAD and then invokes 'git reset --merge' to abort the current in-progress merge and attempt to reconstruct the pre-merge state. The reason for adding this option is to provide a user interface for aborting an in-progress merge that is consistent with the interface for aborting a rebase ('git rebase --abort'), aborting the application of a patch series ('git am --abort'), and aborting an in-progress notes merge ('git notes merge --abort'). The patch includes documentation and testcases that explain and verify the various scenarios in which 'git merge --abort' can run. The testcases also document the cases in which 'git merge --abort' is unable to correctly restore the pre-merge state (look for the '###' comments towards the bottom of t/t7609-merge-abort.sh).

Instead, assume the empty tree for HEAD and do a regular merge. An untracked file will cause the merge to abort and do nothing.

If no branch 'foo' exists but a tag 'foo' does, then git merge foo^ results in Merge branch 'foo' (early part) as a commit message, because the relevant code path checks that refs/heads/foo is a valid refname for writing rather than for reading.

2010-08-15merge: let custom strategies intervene in trivial mergesJonathan Nieder1-0/+1
As v1.6.1-rc1~294^2 (2008-08-23) explains, custom merge strategies do not even kick in when the merge is truly trivial. But they should, since otherwise a custom “--strategy=theirs” is not useful. Perhaps custom strategies should not allow fast-forward either. This patch does not make that change, since it is less important (because it is always possible to explicitly use --no-ff).

2010-08-11unpack_trees: group error messages by typeMatthieu Moy1-0/+1
When an error is encountered, it calls add_rejected_file() which either - directly displays the error message and stops if in plumbing mode (i.e. if show_all_errors is not initialized at 1) - or stores it so that it will be displayed at the end with display_error_msgs(), Storing the files by error type permits to have a list of files for which there is the same error instead of having a serie of almost identical errors. As each bind_overlap error combines a file and an old file, a list cannot be done, therefore, theses errors are not stored but directly displayed.

2010-08-11merge-recursive: porcelain messages for checkoutDiane Gasselin1-1/+1
A porcelain message was first added in checkout.c in the commit 8ccba008 (Junio C Hamano, Sat May 17 21:03:49 2008, unpack-trees: allow Porcelain to give different error messages) to give better feedback in the case of merge errors. This patch adapts the porcelain messages for the case of checkout instead. This way, when having a checkout error, "merge" no longer appears in the error message. While we're there, we add an advice in the case of would_lose_untracked_file. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-08-11Turn unpack_trees_options.msgs into an array + enumMatthieu Moy1-1/+1
The list of error messages was introduced as a structure, but an array indexed over an enum is more flexible, since it allows one to store a type of error message (index in the array) in a variable. This change needs to rename would_lose_untracked -> would_lose_untracked_file to avoid a clash with the function would_lose_untracked in merge-recursive.c.

2010-08-11split_cmdline: Allow caller to access error stringGreg Brockman1-1/+2
This allows the caller to add its own error message to that returned by split_cmdline. Thus error output following a failed split_cmdline can be of the form fatal: Bad alias.test string: cmdline ends with \ rather than error: cmdline ends with \ fatal: Bad alias.test string Signed-off-by: Greg Brockman <gdb@mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-08-06merge-recursive --renormalizeJonathan Nieder1-5/+14
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).

2010-07-02Avoid conflicts when merging branches with mixed normalizationEyvind Bernhardsen1-0/+3
Currently, merging across changes in line ending normalization is painful since files containing CRLF will conflict with normalized files, even if the only difference between the two versions is the line endings. Additionally, any "real" merge conflicts that exist are obscured because every line in the file has a conflict. Assume you start out with a repo that has a lot of text files with CRLF checked in (A): o---C / \ A---B---D B: Add "* text=auto" to .gitattributes and normalize all files to LF-only C: Modify some of the text files D: Try to merge C You will get a ridiculous number of LF/CRLF conflicts when trying to merge C into D, since the repository contents for C are "wrong" wrt the new .gitattributes file. Fix ll-merge so that the "base", "theirs" and "ours" stages are passed through convert_to_worktree() and convert_to_git() before a three-way merge. This ensures that all three stages are normalized in the same way, removing from consideration differences that are only due to normalization. This feature is optional for now since it changes a low-level mechanism and is not necessary for the majority of users. The "merge.renormalize" config variable enables it.

When the user specifies a message, use fmt_merge_msg_shortlog() to append the shortlog. Previously, when a message was specified, we ignored the merge title ("Merge <foo> into <bar>") and shortlog from fmt_merge_msg(). Update the documentation for -m to reflect this too.

In the try_merge_strategy() function, when the strategy is "recursive" or "subtree", the merge_recursive() function is called. Otherwise we launch a "git merge-STRATEGY" process. To make it possible to reuse code that launches a "git merge-STRATEGY" process, this patch refactors this code into a new try_merge_command() function.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds1-0/+1292
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? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. 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>
