1fc59036a99b introduces "--edit" option into "hg commit", but it
doesn't work for "hg commit --amend", because 1fc59036a99b prepares
for editor invocation only around "commitfunc()" internal function,
which is used only for temporary amend commit by "cmdutil.amend()".
Actual commit message editing is executed in "cmdutil.amend()".
This patch invokes editor forcibly when "--edit" option is specified
for "hg commit --amend", even if commit message is specified
explicitly by "--message" or "--logfile".
This patch also removes useless handling for commit message and editor
invocation around "commitfunc()" internal function.
Before this patch, commit message (may be manually edited) for "commit
--amend" is never saved into ".hg/last-message.txt", because it uses
"localrepository.commitctx()" instead of "localrepository.commit()":
saving into ".hg/last-message.txt" is executed only in the latter.
This patch saves commit message for "commit --amend" into
".hg/last-message.txt" just after user editing.
This is the simplest implementation to fix on stable. Editing and
saving commit message for memctx should be centralized into the
framework like "localrepository.commit()" with "editor" argument or so
in the future.
Before this patch, "hg commit --amend --secret" doesn't create new
amend changeset as secret, even though the internal function
"commitfunc()" passed to "cmdutil.amend()" make "phases.new-commit"
configuration as "secret" temporarily.
"cmdutil.amend()" uses specified "commitfunc" only for temporary amend
commit, and creates the final amend commit changeset by
"localrepository.commitctx()" directly with memctx.
This patch creates new amend changeset as secret correctly for
"--secret" option, by changing "phases.new-commit" configuration
temporarily before "localrepository.commitctx()".
You can't close a branch that hasn't got a head.
newbranch + commit --close-branch must fail
newbranch + commit + commit --amend --close-branch must fail
You must not be allowed to close a branch that is not defined.
The `ui.prevent-unstable` option never made it into core. It always behaves
this way when obsolescence feature is enabled.
See changesets caaf2a66c719, f111507ae88a and 51dfebaadebc for details.
The dispatch code now enables filtering of "hidden" changesets globally. The
filter is installed before command and extension invocation. The `--hidden`
switch is now global and disables this filtering for any command.
Code in log dedicated to changeset exclusion is removed as this global filtering
has the same effect.
The active bookmark were moved to the temporary commit. When the transaction
were rollbacked, the bookmark were lost.
We now temporarly disable the bookmark to prevent this effect.
The temporary commit created by amend update the dirstate. If the final commit
fails, we need to invalidate the change made to the dirstate, otherwise the
release of the wlock will write the dirstate created after the rollbacked
temporary commit.
This dirstate writing logic should probably be handled in the same object than
the transaction one. However such change are too big for stable.
Obsolescence marker can represent this situation just fine. The old
version is marked as precursor of the new changeset. All its
descendants become "unstable".
If obsolescence is not enabled we keep the current behavior of
aborting. This new behavior only applies when obsolete is
enabled and is subject to future discussion and changes.
Obsolescence cycle are bad and should be avoided as much as possible. The
current amend implemented touch changeset meta data as few as possible. This
make is easy for amend to result in the same node than a precursors. We add some
deterministic noise in extra to avoid this. In practice, the hex of the amended
changeset is stored in 'amend_source' extra key.
Before this changeset, the extra commit created during amend had
the same description as the final commit. This was a bit confusing
when trying to understand what that extra commit was about.
This changeset changes the description of such commit to:
temporary amend commit for <ammend-commit-hash>
The old behaviour was not a big deal, but would become more confusing
once we use obsolescence marker instead of stripping the precursors.
This also helps if the user restores a strip backup.
Some shells, e.g. ksh89, will emit \" in a here document as ",
while others will emit \". To be sure of getting \", we specify \\".
This gets test-commit-amend.t and test-largefiles.t working on AIX.
New commit from the amend process were created without any phase contraint. If
the amended changeset had a different phase from it's parent, the phases data
were lost.
The changeset ensure the new commit are created in the same phase than the
original changeset.
Destroying history via strip used to invalidate the branchheads cache,
causing it to be regenerated the next time it is read. This is
expensive in large repos. This change converts strip to pass info to
localrepo.destroyed() to enable to it to incrementally update the
cache, improving the performance of strip and other operations that
depend on it (e.g., rebase).
This change also strengthens a bit the integrity checking of the
branchheads cache when it is read, by rejecting the cache if it has
nodes in it that no longer exist.
Messing with the dirstate before the intermediate commit seems error prone.
Instead, commit and recompute the copies with copies.pathcopies(), then use
that with commitctx().
Since copies.pathcopies() does not support file replacement very well, the
whole .renamed() condition in samefile() is removed and the "file replacement
caused by differing copy source" effect is discarded.

The weirdness is --amend let you replace one file with another with same data
and flags if the new file copy record differ from the one in the parent
revision. In theory, there is no problem with this kind of thing, subversion
supports it, but here we see log and status disagree. The reason is log reads
the copy record from the filelog, while status calls copies.pathcopies() which
eventually invokes some expensiveness argument to discard this case (copies.py,
_forwardcopies(), line 132). Since the next patch will side with pathcopies(),
I prefer to call this behaviour a bug.
The --amend flag can be used to amend the parent of the working directory
with a new commit that contains the changes in the parent in addition to
those currently reported by "hg status", if there are any. The old commit
is stored in a backup bundle in ".hg/strip-backup"(see "hg help bundle"
and "hg help unbundle" on how to restore it).
Message, user and date are taken from the amended commit unless specified.
When a message isn't specified on the command line, the editor will open
with the message of the amended commit.
It is not possible to amend public changesets (see "hg help phases") or
changesets that have children.
Behind the scenes, first commit the update (if there is one) as a regular
child of the current parent. Then create a new commit on the parent's
parent with the updated contents. Then change the working copy parent
to this new combined changeset. Finally, strip the amended commit and
update commit created in the beginning.
An alternative (cleaner?) approach of doing this is suggested here:
http://selenic.com/pipermail/mercurial-devel/2012-March/038540.html
It is currently not possible to amend merge commits or recursively,
this can be added at a later time.
