A "merge -c" instruction during "git rebase --rebase-merges" should
give the user a chance to edit the log message, even when there is
otherwise no need to create a new merge and replace the existing
one (i.e. fast-forward instead), but did not. Which has been
corrected.
* pw/rebase-edit-message-for-replayed-merge:
rebase -r: always reword merge -c
|
|
If a merge can be fast-forwarded then make sure that we still edit the
commit message if the user specifies -c. The implementation follows the
same pattern that is used for ordinary rewords that are fast-forwarded.

This is in preparation for using `struct rebase_options` when parsing
options in cmd_rebase__interactive(). Using a string for onto,
restrict_revision and upstream, was a hangover from the scripted version
of rebase. The functions that use these variables are updated to take a
`struct commit`.

As the checkout runs in a separate process our index will be out of date
so it should be discarded. The existing callers are not doing this
consistently so do it here to avoid the callers having to worry about
it.
This fixes some test failures that happen if do_interactive_rebase() is
called without forking rebase--interactive which we will implement
shortly. Running
git rebase -i master topic
starting on master created empty todo lists because all the commits in
topic were marked as cherry-picks. After topic was checked out in
prepare_branch_to_be_rebased() the working tree contained the contents
from topic but the index contained master and the cache entries were
still valid. This meant that diff_populate_filespec() which loads the
blobs when calculating patch-id's ended up reading the contents for
master from the working tree which actually contained topic.

Before commit 356ee4659b ("sequencer: try to commit without forking 'git

When cherry-picking or reverting a sequence of commits and if the final
pick/revert has conflicts and the user uses `git commit` to commit the
conflict resolution and does not run `git cherry-pick --continue` then
the sequencer state is left behind. This can cause problems later. In my
case I cherry-picked a sequence of commits the last one of which I
committed with `git commit` after resolving some conflicts, then a while
later, on a different branch I aborted a revert which rewound my HEAD to
the end of the cherry-pick sequence on the previous branch. Avoid this
potential problem by removing the sequencer state if we're committing or
resetting the final pick in a sequence.

This moves the writing of the comment "Rebase $shortrevisions onto
$shortonto ($command_count commands)" from todo_list_write_to_file() to
append_todo_help().
shortrevisions, shortonto, and command_count are passed as parameters to
append_todo_help().
During the initial edit of the todo list, shortrevisions and shortonto
are not NULL. Therefore, if shortrevisions or shortonto is NULL, then
edit_todo would be true, otherwise it would be false. Thus, edit_todo
is removed from the parameters of append_todo_help().

This refactors skip_unnecessary_picks() to work on a todo_list. As this
function is only called by complete_action() (and thus is not used by
rebase -p), the file-handling logic is completely dropped here.
Instead of truncating the todo list’s buffer, the items are moved to
the beginning of the list, eliminating the need to reparse the list.
This also means its buffer cannot be directly written to the disk.
rewrite_file() is then removed, as it is now unused.

complete_action() used functions that read the todo-list file, made some
changes to it, and wrote it back to the disk.
The previous commits were dedicated to separate the part that deals with
the file from the actual logic of these functions. Now that this is
done, we can call directly the "logic" functions to avoid useless file
access.
The parsing of the list has to be done by the caller. If the buffer of
the todo list provided by the caller is empty, a `noop' command is
directly added to the todo list, without touching the buffer.

This refactors rearrange_squash() to work on a todo_list to avoid
redundant reads and writes. The function is renamed
todo_list_rearrange_squash().
The old version created a new buffer, which was directly written to the
disk. This new version creates a new item list by just copying items
from the old item list, without creating a new buffer. This eliminates
the need to reparse the todo list, but this also means its buffer cannot
be directly written to the disk.
As rebase -p still need to check the todo list from the disk, a new
function is introduced, rearrange_squash_in_todo_file().
complete_action() still uses rearrange_squash_in_todo_file() for now.
This will be changed in a future commit.

This refactors sequencer_add_exec_commands() to work on a todo_list to
avoid redundant reads and writes to the disk.
Instead of inserting the `exec' commands between the other commands and
re-parsing the buffer at the end, they are appended to the buffer once,
and a new list of items is created. Items from the old list are copied
across and new `exec' items are appended when necessary. This
eliminates the need to reparse the buffer, but this also means we have
to use todo_list_write_to_disk() to write the file.
todo_list_add_exec_commands() and sequencer_add_exec_commands() are
modified to take a string list instead of a string -- one item for each
command. This makes it easier to insert a new command to the todo list
for each command to execute.
sequencer_add_exec_commands() still reads the todo list from the disk,
as it is needed by rebase -p.
complete_action() still uses sequencer_add_exec_commands() for now.
This will be changed in a future commit.

The author.email, author.name, committer.email and committer.name
settings are analogous to the GIT_AUTHOR_* and GIT_COMMITTER_*
environment variables, but for the git config system. This allows them
to be set separately for each repository.
Git supports setting different authorship and committer
information with environment variables. However, environment variables
are set in the shell, so if different authorship and committer
information is needed for different repositories an external tool is
required.
This adds support to git config for author.email, author.name,
committer.email and committer.name settings so this information
can be set per repository.
Also, it generalizes the fmt_ident function so it can handle author vs
committer identification.

This introduces a new function to recreate the text of a todo list from
its commands and write it to a file. This will be useful as the next
few commits will change the use of the buffer in struct todo_list so it
will no longer be a mirror of the file on disk.
This functionality already exists in todo_list_transform(), but this
function was made to replace the buffer of a todo list, which is not
what we want here. Thus, the part of todo_list_transform() that
replaces the buffer is dropped, and the function is renamed
todo_list_to_strbuf(). It is called by todo_list_write_to_file() to
fill the buffer to write to the disk.
todo_list_write_to_file() can also take care of appending the help text
to the buffer before writing it to the disk, or to write only the first
n items of the list. This feature will be used by
skip_unnecessary_picks(), which has to write done commands in a file.

The 'arg' field of todo_item used to store the address of the first byte
of the parameter of a command in a todo list. It was associated with
the length of the parameter (the 'arg_len' field).
This replaces the 'arg' field by 'arg_offset'. This new field does not
store the address of the parameter, but the position of the first
character of the parameter in the buffer. todo_item_get_arg() is added
to return the address of the parameter of an item.
This will prevent todo_list_add_exec_commands() from having to do awful
pointer arithmetics when growing the todo list buffer.

"git cherry-pick -m1" was forbidden when picking a non-merge
commit, even though there _is_ parent number 1 for such a commit.
This was done to avoid mistakes back when "cherry-pick" was about
picking a single commit, but is no longer useful with "cherry-pick"
that can pick a range of commits. Now the "-m$num" option is
allowed when picking any commit, as long as $num names an existing
parent of the commit.
Technically this is a backward incompatible change; hopefully
nobody is relying on the error-checking behaviour.
