Commit hashes are a useful way to ensure the content of commits made in the
tests are not changing, even if we don't query every aspect of every commit.
(And some properties, like extras, are rarely printed at all.)
Many of the rebase log -G calls didn't show hashes; by adding hashes to places
that weren't showing them we can help protect those tests from unwanted
changes.
Differential Revision: https://phab.mercurial-scm.org/D1650
Upon pull or unbundle, we display a message with the range of new revisions
fetched. This revision range could readily be used after a pull to look out
what's new with 'hg log'. The algorithm takes care of filtering "obsolete"
revisions that might be present in transaction's "changes" but should not be
displayed to the end user.
This patch migrates rebase to use scmutil.cleanupnodes API. It simplifies
the code and makes rebase code reusable inside a transaction.
This is a BC because the backup file is no longer strip-backup/*-backup.hg,
but strip-backup/*-rebase.hg. The latter looks more reasonable since the
directory name is "strip-backup" so there is no need to repeat "backup".
I think the backup file name change is probably fine as a BC, since we have
changed it before (2e51c9a7a08f) and didn't get complains. The end result
of this series will be a much more consistent and unified backup names:
command | old backup file suffix | new backup file suffix
-------------------------------------------------------------------
amend | amend-backup.hg | amend.hg
histedit | backup.hg (could be 2 files) | histedit.hg (single file)
rebase | backup.hg | rebase.hg
strip | backup.hg | backup.hg
(note: backup files are under .hg/strip-backup)
It also fixes issue5606 as a side effect because the new "delayedstrip" code
path will carefully examine nodes (safestriproots) to make sure orphaned
changesets won't get stripped by accident.
Some warning messages are changed to the new "warning: orphaned descendants
detected, not stripping HASHES", which provides more information about
exactly what changesets are left behind.
Another minor behavior change is when there is an obsoleted changeset with a
successor in the destination branch, bookmarks pointing to that obsoleted
changeset will not be moved. I have commented in test-rebase-obsolete.t
explaining why that is more desirable.
We want to explicitly test the next behavior. We add this test in its own
changeset to make the test change from the behavior change as clean as possible.
As we will make 'rebase' behave more like 'merge', it will no longer pick
'max(branch(.))' as the default destination. We have to hard code the expected
destination is multiple tests where it matters. After a careful inspection none
of theses tests really cares about the default destination behavior and just
omitted one out of laziness.
These tests do not care about that extra branch at all. In future changeset we
will make rebase behave like merge and abort in case of an ambiguous destination
(eg: multiple other heads) and that extra branch will make the command
invocation breaks.
We preventively remove this extra branch from the relevant tests in an
independant changeset to reduce noise and increase confidence in the final
change.
Rather than look for the lowest revision, see if the rebase state is tracking
the parents of this revision. Otherwise we can't handle multiple revisions in
one rebase that includes a merge revision.
Fixes issue5044.
Before this patch rebase --continue with specified --tool option outputs
warnings "tool option will be ignored". It is false statement because
in case of any merge conflicts it uses specified tool to resolve it.
This patch makes this warning appears only when user specified --tool
when running rebase --abort , in this case tool doesn't have any
sense
The phase of the pending commit depends on the parent of the working directory
and on the phases.newcommit configuration.
First, this information rather depend on the commit line which describe the
pending commit.
Then, we only want to be advertised when the pending phase is going to be higher
than the default new commit phase.
So the format will change from
$ hg summary
parent: 2:ab91dfabc5ad
foo
parent: 3:24f1031ad244 tip
bar
branch: default
commit: 1 modified, 1 unknown, 1 unresolved (merge)
update: (current)
phases: 1 secret (secret)
to
parent: 2:ab91dfabc5ad
foo
parent: 3:24f1031ad244 tip
bar
branch: default
commit: 1 modified, 1 unknown, 1 unresolved (merge) (secret)
update: (current)
phases: 1 secret
The number of draft and secret changesets are currently not summarized.
This is an important information because the number of drafts give some rough
idea of the number of outgoing changesets in typical workflows, without needing
to probe a remote repository. And a non-zero number of secrets means that
those changeset will not be pushed.
If the repository is "dirty" - some draft or secret changesets exists - then
summary will display a line like:
phases: X draft, Y secret (public)
The phase in parenthesis corresponds to the highest phase of the parents of
the working directory, i.e. the current phase.
By default, the line is not printed if the repository is "clean" - all
changesets are public - but if verbose is activated, it will display:
phases: (public)
On the other hand, nothing will be printed if quiet is in action.
A few tests have been added in test-phases.t to cover the -v and -q cases.
Previously, a backup bundle could overwrite an existing bundle and cause user
data loss. For instance, if you have A<-B<-C and strip B, it produces backup
bundle B-backup.hg. If you then hg pull -r B B-backup.hg and strip it again, it
overwrites the existing B-backup.hg and C is lost.
The fix is to add a hash of all the nodes inside that bundle to the filename.
Fixed up existing tests and added a new test in test-strip.t
Show status messages while rebasing, similar to what graft do:
rebasing 12:2647734878ef "fork" (tip)
This gives more context for the user when resolving conflicts.
Globbing the hash made it harder to maintain tests with run-tests -i when it
was so far by the generated test output.
The hashes are stable and we just need to add a (glob).
The new rebase revset didn't check for the case when there are no common
ancestors. Now it does. The new behavior should be the same as the pre-3.2
behavior. Added a test.
A common mistake can be to type 'hg rebase -i' to discover interactive history
editing. We add a -i/--interactive flag as discussed in the sprint and deprecate
it right away, but hint people using it to use histedit instead.
The recently introduced message was:
no unresolved files; you may continue your unfinished operation
This had three problems:
- looks a bit like an error message because it's not saying "we've
just resolved the last file"
- refers to "unfinished operation", which won't be the case with
"update" or "merge"
- introduces semicolons to error messages, which is stylistically
questionable
I've simplified this to:
no more unresolved files
In the future, if we want to prompt someone to continue a particular operation, we should use
a hint style:
no more unresolved files
(use 'hg graft --continue' to finish grafting)
When using resolve, users often have to consult with the output of |hg
resolve -l| to see if any unresolved files remain. This step is tedious
and adds overhead to resolving.
This patch will notify a user if there are no unresolved files remaining
after executing |hg resolve|::
no unresolved files; you may continue your unfinished operation
The patch stops short of telling the user exactly what command should be
executed to continue the unfinished operation. That is because this
information is not currently captured anywhere. This would make a
compelling follow-up feature.
The documentation says we exit 1 if we have nothing to do, so avoid
breaking that contract when we're passed an empty revset.
This was changed in http://www.selenic.com/hg/rev/1d4f2abc281b to
improve the error message; keep the improved message, just not the
abort.
Before it just said 'nothing to rebase'.
Now 'if "base" is an empty set:
abort: empty "base" revision set - can't compute rebase set
If the set of changesets to rebase can't be found from "base", it will fail as
before but with more explanation of what the problem was.
The name of the "base" option is not obvious - it is more like "samples
identifying the branch to rebase". The error messages for problems with the
specified "base" value will use that term and might thus also not be obvious,
but at least they are consistent with the option name. The name "base" will not
be used if the base only was specified implicitly as the working directory
parent.
Before, it just said 'nothing to rebase' in this case. Now, it aborts
mentioning the reason: 'empty "source" revision set'.
Specifying revisions that cannot be rebased is a 'soft' error, but specifying
an empty set deserves an abort that explains exactly what the problem is.
Before, it just said 'nothing to rebase' in this case. Now, it aborts

Prior to this changeset, rebase always left the working directory as a parent of
the last rebased changeset. The is dubious when, before the rebase, the working
directory was not a parent of the tip most rebased changeset.
With this changeset, we move the working directory back to its original parent.
If the original parent was rebased, we use it's successors.
This is a step toward solving issue3813 (rebase loses active bookmark if it's
not on a head)
Rebase now behaves as if --detach was always passed. Non-merges are
rebased as non-merges, regardless of their parent being an ancestor of
the destination. Merges will usually be rebased as merges unless both of
their parents are ancestors of the destination, or one of their parents
is pruned when rebased.
This only alters the behavior of rebase when using the --source/--rev
options. --detach option is deprecated.
All test changes were carefully validated.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
This option allow a strict set of revision to be specified instead of using -s
or -b. Rebase will refuse start if striping rebased changeset will strip non
rebased changeset. Rebase will refuse to work on set with multiple root.
The buildstate function now take a set of revs. Logic related to --source and
--base option have been moved in the main rebase function.
In the process this fixes a bug where the wrong source changeset might be pick.
This explain the changes in hgext/rebase.py
We only deny rebasing onto direct parent. Thanks to the ancestor argument of
merge. the "implementation" of this feature only consist in loosing the check
and imply detach when rebasing on ancestor.
