[PATCHv7 1/3] git-rebase -i: add command "drop" to remove a commit
Instead of removing a line to remove the commit, you can use the
command "drop" (just like "pick" or "edit"). It has the same effect as
deleting the line (removing the commit) except that you keep a visual
trace of your actions, allowing a better control and reducing the
possibility of removing a commit by mistake.

[PATCHv7 2/3] git rebase -i: warn about removed commits
Check if commits were removed (i.e. a line was deleted) and print
warnings or stop git rebase depending on the value of the
configuration variable rebase.missingCommitsCheck.
This patch gives the user the possibility to avoid silent loss of
information (losing a commit through deleting the line in this case)
if he wants.
Add the configuration variable rebase.missingCommitsCheck.
- When unset or set to "ignore", no checking is done.
- When set to "warn", the commits are checked, warnings are
displayed but git rebase still proceeds.
- When set to "error", the commits are checked, warnings are
displayed and the rebase is stopped.
(The user can then use 'git rebase --edit-todo' and
'git rebase --continue', or 'git rebase --abort')
rebase.missingCommitsCheck defaults to "ignore".

[PATCHv7 3/3] git rebase -i: add static check for commands and SHA-1
Check before the start of the rebasing if the commands exists, and for
the commands expecting a SHA-1, check if the SHA-1 is present and
corresponds to a commit. In case of error, print the error, stop git
rebase and prompt the user to fix with 'git rebase --edit-todo' or to
abort.
This allows to avoid doing half of a rebase before finding an error
and giving back what's left of the todo list to the user and prompt
him to fix when it might be too late for him to do so (he might have
to abort and restart the rebase).

rebase -i: drop, missing commits and static checks
Changes between versions:
In t3404:
Changed 'test_rebase_end' to 'rebase_setup_and_clean'.
Changed the indentation in 'rebase_setup_and_clean'.
Changed the names of the branches created in my tests (avoid names
like 'tmp').
Added 'test_might_fail' in front of 'git branch -D'.
Remove 'test_config rebase.missingCommitsCheck error' in the last test
('static check of bad SHA-1') because it was useless.
In git-rebase--interactive.sh:
Errors found in commands and SHA-1 (static check) are displayed on the
spot.
I used return values to signal to the calling functions if there is an
error.
The whole while block in 'check_bad_cmd_and_sha' with the return is in a
'(
[...]
)'
block because 'retval' would not have been correctly affected when
getting out of the loop since the while is in a pipe.
A thought occured to me:
Shouldn't all the checking also be called in a 'rebase --continue',
considering that it can be called after a 'rebase --edit-todo' ?
(Right now it is only called after closing the editor in 'rebase -i')

[PATCH/RFCv5 3/3] git rebase -i: add static check for commands and SHA-1
Check before the start of the rebasing if the commands exists, and for
the commands expecting a SHA-1, check if the SHA-1 is present and
corresponds to a commit. In case of error, print the error, stop git
rebase and prompt the user to fix with 'git rebase --edit-todo' or to
abort.
This allows to avoid doing half of a rebase before finding an error
and giving back what's left of the todo list to the user and prompt
him to fix when it might be too late for him to do so (he might have
to abort and restart the rebase).

[PATCH/RFCv5 2/3] git rebase -i: warn about removed commits
Check if commits were removed (i.e. a line was deleted) and print
warnings or stop git rebase depending on the value of the
configuration variable rebase.missingCommitsCheck.
This patch gives the user the possibility to avoid silent loss of
information (losing a commit through deleting the line in this case)
if he wants.
Add the configuration variable rebase.missingCommitsCheck.
- When unset or set to "ignore", no checking is done.
- When set to "warn", the commits are checked, warnings are
displayed but git rebase still proceeds.
- When set to "error", the commits are checked, warnings are
displayed and the rebase is stopped.
(The user can then use 'git rebase --edit-todo' and
'git rebase --continue', or 'git rebase --abort')
rebase.missingCommitsCheck defaults to "ignore".

In git-rebase--interactive, in the error case of check_todo_list, I
added 'git checkout $onto' so that using 'die' for the error allows
to use 'git rebase --edit-todo' (otherwise HEAD would not have been
changed and it still would be placed after the commits of the
rebase).
Since now it doesn't abort the rebase, the documentation and the
messages in the case error have changed.
I moved the error case away from the initial test case for missing
commits as to prepare for 3/3 part of the patch. It is something that
was advised by Eric Sunshine when I checked both missing and
duplicated commits, but that I removed it when removing the checking
for duplicated commits since there was only one test. However I add
it again since 3/3 will add more checking.
I use the variable raiseError that I affect if the error must be
raised instead of testing directly because I think it makes more
sense with 3/3 and if we add other check in the future since it adds
more possible errors (the test for the error case if not something
like 'if (test checkLevel = error && test -s todo.miss) || test cond2
|| test cond3 || ...').
I am wondering if a check_todo_list call should be added in the
'--continue' part of the code: with this patch, the checking is only
done once, if the user doesn't edit correctly with 'git rebase
--edit-todo', it won't be picked by this.
In the tests in t3404 I now also test that the warning/error messages
are correct.
I tried to not change this patch too much since it was already
heavily reviewed, but there are some changes (mostly the ones
mentionned above).

[PATCH/RFCv5 1/3] git-rebase -i: add command "drop" to remove a commit
Instead of removing a line to remove the commit, you can use the
command "drop" (just like "pick" or "edit"). It has the same effect as
deleting the line (removing the commit) except that you keep a visual
trace of your actions, allowing a better control and reducing the
possibility of removing a commit by mistake.

[PATCH/RFCv2 0/2] rebase -i : drop command and removed commits
- [PATCH 1/2] git-rebase -i: add command "drop" to remove a commit The 'drop' command is added as a way to explicitely remove commits in git rebase -i. This patch does not prevent users from commenting the line, removing the line or using the 'noop' command if they want to. While the 'noop' command has the same effect, it doesn't seem to be the right use for it since 'noop' merely ignores everything that follows, in particular writing 'noop ' can be confusing. Commenting a line also has the same effect but the 2/2 part of the patch is not made for working correctly with comments (though it still works with 'noop'). This command is inspired by the command 'drop' in histedit of Mercurial (though in the idea, it is not made to make migrants from Mercurial feel better but rather because it seems like a good idea). For the 'drop' command, maybe instead of just doing the same thing as noop, checking if the SHA-1 that supposedly follow does exist could be a good idea. - [PATCH 2/2] git rebase -i: warn about removed commits Since the default behaviour is 'ignore', meaning that no checking is done and no warning is displayed, users that are used to remove the lines to remove a commit can still do so without changing their configuration. However this patch gives the user the possibility to avoid silent loss of information if he wants. Regarding the comments of v1 : The dupplicated commits are not checked anymore ((about the review by Eric Sunshine) thus the error case stays within the warning test, now that we only have one test for warnings). The list of removed commits is now shown in the format ' ' instead of '', this was done following an idea given by Matthieu Moy outside of the mailing list. Because of this some code have been added and modified and thus need reviewing. A test has been added to check the correct behaviour of the error configuration. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH/RFCv2 1/2] git-rebase -i: add command "drop" to remove a commit
Instead of removing a line to remove the commit, you can use the
command "drop" (just like "pick" or "edit"). It has the same effect as
deleting the line (removing the commit) except that you keep a visual
trace of your actions, allowing a better control and reducing the
possibility of removing a commit by mistake.

[PATCH/RFC 1/2] git-rebase -i: Add key word "drop" to remove a commit
Instead of removing a line to remove the commit, you can use the key
word "drop" (just like "pick" or "edit"). It has the same effect as
deleting the line (removing the commit) except that you keep a visual
trace of your actions, allowing a better control and reducing the
possibility of removing a commit by mistake.

[PATCH/RFC 2/2] git rebase -i: Warn removed or dupplicated commits
Check if commits were removed (i.e. a line was deleted) or dupplicated
(e.g. the same commit is picked twice), can print warnings or abort
git rebase according to the value of the configuration variable
rebase.checkLevel.
Add the configuration variable rebase.checkLevel.
- When unset or set to "IGNORED", no checking is done.
- When set to "WARN", the commits are checked, warnings are
displayed but git rebase still proceeds.
- When set to "ERROR", the commits are checked, warnings are
displayed and the rebase is aborted.
