2014-03-28Merge branch 'bp/commit-p-editor'Libravatar Junio C Hamano1-3/+3
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 wordsLibravatar Junio 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 possibleLibravatar Nguyễn 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 optionLibravatar Miklos 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.

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. After the integrator saves the message in the editor, they are meant to go away and that is why they are commented out. When a merge is recorded without editing the generated message, however, its contents do not go through the normal stripspace() and these lines are left in the merge.

When future commits add more quality checks on the identity, each of these callers would want to use those checks, too.

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.

Config option diff.statGraphWidth=<width> is equivalent to --stat-graph-width=<width>, except that the config option is ignored by format-patch. 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.

2012-02-23merge: do not trust fstat(2) too much when checking interactivenessLibravatar Junio C Hamano1-1/+1
The heuristic used by "git merge" to decide if it automatically gives an editor upon clean automerge is to see if the standard input and the standard output is the same device and is a tty, we are in an interactive session. "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>
