The setting of a now-unused member '.pretty_given' in the sequencer
machinery has been removed.
* en/sequencer-lose-pretty-given:
sequencer: remove unnecessary variable setting
|
|
As of 4557f1add261 (rebase--helper: add a builtin helper for interactive
rebases, 2017-02-09), continuing an interactive rebase uses the builtin
sequencer, which spawns `git commit`.
The child may trigger auto-maintenance, which may need to replace files
for which the sequencer still holds resources. See
https://github.com/git-for-windows/git/issues/6315: on Windows, this
produces unlink retry prompts that cannot succeed while the sequencer
waits for the child.
Resources such as file handles or memory mappings must be released
before spawning a command that may run auto-maintenance, as established
by 28d04e1ec197 (run-command: offer to close the object store before
running, 2021-09-09): release the ODB file handles and memory mappings,
so that auto-gc can repack (potentially deleting existing packfiles in
the process); If the sequencer needs to access the ODB afterwards, it
will gracefully (re-)open the ODB.
Release the sequencer's ODB before spawning `git commit`. The regression
test uses the legacy-delete trick introduced by 69ed0e35a754 (mingw:
optionally use legacy (non-POSIX) delete semantics, 2026-05-07) to
trigger the failure on modern Windows.

revs.pretty_given is only ever read in builtin/log.c, and nothing from
builtin/log.c is ever called from sequencer.c. So setting this variable
cannot do anything.
This was introduced in commit 62db524779 ("rebase -i: generate the
script via rebase--helper", 2017-07-14), which used `git rev-list` even
though its commit message describes the logic as having been based on
`git log`. Because of this, I am guessing this line was copied or
ported from part of builtin/log.c without recognizing that this line was
not doing anything and could be removed.
It's certainly not doing anything now, though, so remove it.

Two bugs in how 'git rebase' handles skipped 'fixup' and 'squash'
commands have been fixed. One bug caused an incorrect commit count to
be shown in the template message when multiple commands were skipped,
and another prevented the editor from opening when the final command
in a chain containing 'fixup -c' was skipped.

rebase: remember fixup -c after skipping fixup/squash

The rebase post-rewrite notes-copying logic has been corrected. When
a commit is dropped during rebase (e.g., because its changes are
already upstream), it is no longer recorded as rewritten, preventing
its notes from being copied to an unrelated commit.
* pw/rebase-drop-notes-with-commit:
sequencer: do not record dropped commits as rewritten

sequencer: remove unnecessary "or" in pick_one_commit()

|

When the final command in a chain of "fixup" and "squash" commands
is skipped, we should prompt the user to edit the commit message
if the chain contains a "fixup -c" command that was not skipped.
Unfortunately, commit_staged_changes() only looks for completed "squash"
commands and so does not prompt the user to edit the message. Fix
this by recording whether a fixup command has the "-c" flag set and
then checking whether we have seen either a "fixup -c" or a "squash"
command. Add regression tests for skipping a command in the middle
of the chain (which currently works but has no test coverage), and
for skipping the final command (which is fixed by this patch).

When the sequencer processes a chain of "fixup" and "squash" commands
it keeps a list of the commands that have been executed. If there are
conflicts, then the list is saved when the rebase stops for the user to
resolve them. When the rebase resumes, the list is loaded and is used
to initialize the count of how many "fixup" and "squash" commands have
been processed; if a command has been skipped with "git rebase --skip",
then the last command needs to be popped off the end of the list.
To count the number of commands, commit_staged_changes() uses the
number of newlines in the file plus one. This is due to the slightly
unusual way the list is constructed - instead of appending a newline
when a command is added, a newline is inserted before the command
if the current count is greater than zero. Therefore, when we pop a
skipped command off the list, we should also remove the newline that
precedes it. Otherwise, when a new command is added, a blank line
will be left before it, which will contribute to the fixup count the
next time the file is read. Unfortunately, the preceding newline is
not removed, leading to an incorrect count. Fix this by removing the
newline that appears before the skipped command.
In addition to fixing the code that removes a skipped command from the
list, the code that reads the list is fixed to skip blank lines. We
have had reports of users starting a rebase with one version of
git and continuing it with another. Often this happens because the
version of git bundled with an IDE or TUI differs from the one used
at the command line. By fixing both the reading and writing ends of
the problem we ensure the count is correct when an older version of
git reads the fixup file written by a newer version and vice versa.
Triggering the incorrect count requires the user to skip two "fixup" or
"squash" commands before the final command in the chain. An existing
test is extended to prevent future regressions. The consequence of
miscounting is not serious: we just print the wrong count in the
header of the commit message template.

If a commit gets dropped because its changes are already upstream
then we should not record it as rewritten. As well as confusing any
post-rewrite hooks, it means we end up copying the notes from the
dropped commit to the commit that was picked immediately before the
one that was dropped.
While we do not want to record the dropped commit as rewritten, if
it is the final commit in a chain of fixups then we need to flush
the list of rewritten commits. The behavior of an "edit" command
where the commit is dropped is changed so that "rebase --continue"
will not amend the previous pick. However, as the code comment notes
it will still be erroneously recorded as rewritten when the rebase
continues. That will need to be addressed separately along with not
recording skipped commits as rewritten.
The initialization of "drop_commit" is moved to ensure it is initialized
when rewording a fast-forwarded commit.

Rather than using an integer where -1 is an error, 0 is success and 1
indicates there were conflicts, use an enum. This is clearer and lets
us add a separate return value for commits that are dropped because
they become empty in the next commit.
Note we continue to use "return error(...)" to return errors and
take advantage of C's lax typing of enums

Unless we're rebasing, all we do in pick_one_commit() is call
do_pick_commit() and return its result. Simplify the code by returning
early if we're not rebasing so that we don't have to repeatedly call
is_rebase_i() in the rest of the function. Note that there are a couple
of conditions that do not call is_rebase_i() but they check for either
an "edit" or a "fixup" command, both of which imply we're rebasing.
The only block that does not return early is the one guarded by
"!res". Move the return into that block to make it clear that after
recording the commit as rewritten, all we do is return from the
function.
As the conditional blocks are all mutually exclusive (either the
conditions are mutually exclusive, or an earlier conditional block
that would match a later one contains a "return" statement) chain
them together with "else if" to make that clear.
While we could remove "res" from the conditions below "if (!res)"
they are left alone because, when we start using an enum in the next
commit, it makes it clear that these clauses are handling cases where
there are conflicts.

item->commit holds the commit to be picked and so it must be non-NULL
otherwise pick_one_commit() would not know which commit to pick.
It is also unconditionally dereferenced in do_pick_commit() which is
called at the top of this function. Therefore the check to see if it
is non-NULL is superfluous.

Commit e032abd5a0 (rebase: fix rewritten list for failed pick,
2023-09-06) introduced an early return when res == -1, so if
we enter this conditional block then res is positive. After the
last couple of commits the only possible positive value is 1. That
means we can simplify the code by removing the conditional call to
intend_to_amend() and have error_failed_squash() request that it is
called in error_with_patch() instead.

If "git commit" fails to run then run_git_commit() returns -1 which
causes the current command to be rescheduled. This is incorrect as
we have successfully picked the commit and have written all the state
files we need to successfully commit when the user continues. Fix this
by converting -1 to 1 which matches what do_merge() does.

If an external merge strategy cannot merge (for example because it
would overwrite an untracked file) it exits with a non-zero exit
code other than 1. This should be treated differently from a merge
with conflicts, which is signaled by an exit code of 1, because, as
the merge failed, we need to reschedule the last pick. The caller
expects us to return -1 in this case. Also reschedule without trying
to merge if the commit message cannot be written as that prevents us
from successfully picking the commit.

In a subsequent commit we'll introduce a new caller to
`reset_working_tree()` that really only wants to update the index and
working tree, without updating any references. Introduce a new flag that
makes the caller opt in to updating HEAD and adapt all callers to set
that flag.
Note that in a previous iteration we instead introduced a flag that made
callers opt out of updating any references. This was somewhat awkward
though because we already have the `UPDATE_ORIG_HEAD` flag, so the
result was somewhat inconsistent.

In a subsequent commit we're about to adapt `reset_head()` so that the
reference update to HEAD is optional, only. At this point the function
starts to feel misnamed, as it doesn't necessarily have anything to do
with the HEAD reference anymore. The gist of the function then is that
we reset the working tree to a specific new commit, updating both the
index and the checked-out files.
Rename it to `reset_working_tree()` to better reflect that.
Note that we don't adjust the flags yet. This will happen in a
subsequent commit.

Move the code that parses todo commands into a separate function so
that it can be shared with "git status" in the next commit. As we
know the input is NUL terminated we do not pass a pointer to the end
of the line and instead test for a blank line by looking for NUL, CR
LF, or LF. We use starts_with() instead of starts_with_mem() for the
same reason. This results in slightly different behavior when there
a CR at the start of the line that is not followed by LF. Previously
such a line was treated as a comment rather than an invalid line.

Add a function for adding the full hexadecimal hash value of an object
ID to a strbuf. It's thread-safe and slightly more efficient than using
strbuf_addstr() with oid_to_hex() because it doesn't have to determine
the length of the string or copy it from the intermediate static buffer.
Add and apply a semantic patch to use it throughout the code base.

The following Git configuration breaks git rebase --update-refs:
[rebase]
instructionFormat = %s%d
The '%d' format requests all available decorations for a commit,
filling the global decoration table with all of them,
which --update-refs then uses to populate 'update-ref' instructions
in the rebase todo list.
Specifically, this results in the following instruction:
update-ref HEAD
The todo parser then rejects the instruction:
error: update-ref requires a fully qualified refname e.g. refs/heads/HEAD
error: invalid line 3: update-ref HEAD
To fix, ignore decorations that are not local branches
when scanning through the table.
This matches the documented contract:
it moves branch refs under refs/heads/
and leaves display-only decorations (HEAD, tags, etc.) alone.
Verification:
A regression test that fails without this fix is included.

When switching branches with "git checkout -m", the attempted merge
of local modifications may cause conflicts with the changes made on
the other branch, which the user may not want to (or may not be able
to) resolve right now. Because there is no easy way to recover from
this situation, we discouraged users from using "checkout -m" unless
they are certain their changes are trivial and within their ability
to resolve conflicts.
Teach the -m flow to create a temporary stash before switching and
reapply it after. On success, the stash is silently applied and
the list of locally modified paths is shown, same as a successful
"git checkout" without "-m".
If reapplying causes conflicts, the stash is kept and the user is
told they can resolve and run "git stash drop", or run "git reset
--hard" and later "git stash pop" to recover their changes.

"git replay" (experimental) learns, in addition to "pick" and
"replay", a new operating mode "revert".
* sa/replay-revert:
replay: add --revert mode to reverse commit changes
sequencer: extract revert message formatting into shared function
|
|
The logic for formatting revert commit messages (handling "Revert" and
"Reapply" cases, appending "This reverts commit <ref>.", and handling
merge-parent references) currently lives inline in do_pick_commit().
The upcoming replay --revert mode needs to reuse this logic.
Extract all of this into a new sequencer_format_revert_message()
function. The function takes a repository, the subject line, commit,
parent, a use_commit_reference flag, and the output strbuf. It handles
both regular reverts ("Revert "<subject>"") and revert-of-revert cases
("Reapply "<subject>""), and uses refer_to_commit() internally to
format the commit reference.
Update refer_to_commit() to take a struct repository parameter instead
of relying on the_repository, and a bool instead of reading from
replay_opts directly. This makes it usable from the new shared function
without pulling in sequencer-specific state.

There are double frees and leaks around setup_revisions() API used
in "git stash show", which has been fixed, and setup_revisions()
API gained a wrapper to make it more ergonomic when using it with
strvec-manged argc/argv pairs.
* jk/setup-revisions-freefix:
revision: retain argv NULL invariant in setup_revisions()
treewide: pass strvecs around for setup_revisions_from_strvec()
treewide: use setup_revisions_from_strvec() when we have a strvec
revision: add wrapper to setup_revisions() from a strvec
revision: manage memory ownership of argv in setup_revisions()
stash: tell setup_revisions() to free our allocated strings

"git rebase -i" failed to clean-up the commit log message when the
command commits the final one in a chain of "fixup" commands, which
has been corrected.
* pw/rebase-i-cleanup-fix:
sequencer: remove VERBATIM_MSG flag
rebase -i: respect commit.cleanup when picking fixups

The previous commit converted callers of setup_revisions() with a strvec
to use the safer and easier _from_strvec() variant.
Let's now convert spots that don't directly have a strvec, but receive
an argc/argv pair that eventually comes from one. We'll instead pass the
strvec down to the point where we call setup_revisions().
That makes these functions slightly less flexible if they were to grow
other callers that don't use strvecs, but this rigidity is buying us
some safety. It is only safe to pass the free_removed_argv_elements
option to setup_revisions() if we know the elements of argv/argc are
allocated on the heap. That isn't communicated in the type system when
we are passed the bare elements. But if we get a strvec, we know that
the elements are allocated strings.
And at any rate, each of these modified functions has only a single
caller (that has a strvec), so the loss of flexibility is unlikely to
ever matter.

As the last commit deleted the only user of VERBATIM_MSG remove
it. This reverts remaining parts of commit f7d42ceec52 (rebase -i:
do leave commit message intact in fixup! chains, 2021-01-28) that
were not deleted by the last commit.

If the user uses a prepare-commit-msg hook to add comments to the
commit message template and sets commit.cleanup to remove them when the
commit is created then the comments will not be removed when rebase
commits the final command in a chain of "fixup" commands[1]. This
happens because f7d42ceec52 (rebase -i: do leave commit message intact
in fixup! chains, 2021-01-28) started passing the VERBATIM_MSG flag
when committing the final command in a chain of "fixup" commands. That
change was added in response to a bug report[2] where the commit
message was being cleaned up when it should not be. The cause of that
bug was that before f7d42ceec52 the sequencer passed CLEANUP_MSG
when committing the final fixup. That commit should have simply
removed the CLEANUP_MSG flag, not changed it to VERBATIM_MSG. Using
VERBATIM_MSG ignores the user's commit.cleanup config when committing
the final fixup which means it behaves differently to an ordinary
"pick" command which respects commit.cleanup.
Fix this by not setting an explicit cleanup flag when committing the
final fixup which matches the way "pick" commands behave. The test
added in f7d42ceec52 is replaced with one that checks that "fixup"
and "pick" commands do not clean up the message when commit.cleanup
is not set and do clean up the message when it is set.
