histedit: use scmutil.cleanupnodes (BC) This is marked as BC because the strip backup file name has changed.

histedit: unify strip backup files on success (BC) Previously we wrote two different strip backup files on success. This patch unifies them. It will make scmutil.cleanupnodes migration more smooth.

histedit: pass multiple nodes to strip (BC) Previously, histedit.cleanupnode pass root nodes one by one. Since repair.strip takes multiple nodes and can handle them just fine, pass all strip roots at once. This is BC because the number of strip backup files may change from N to 1.

histedit: remove "name" parameter from cleanupnode functions The "name" parameter is not used any longer so let's remove it.

histedit: remove "should strip" debug message The debug message was not used anywhere. Removed it to make scmutil.cleanupnodes migration easier to reason about.

histedit: move topmost bookmark movement to a separate function histedit treats topmost bookmark movement specially. The rest of the bookmark movement could be handled by scmutil.cleanupnodes. So let's move the special logic out to make the patch easier to review.

histedit: remove moving bookmarks message on verbose (BC) This is more consistent with other commands, like "commit -v" won't show bookmark movement messages. It will make migrating to scmutil.cleanupnodes easier.

test-largefiles-update: conditionalize output instead of tests

test-status-rev: conditionalize output instead of tests

test-mq: conditionalize output instead of tests

test-annotate: conditionalize output instead of tests

test-addremove: conditionalize output instead of tests

test-tools: conditionalize output instead of tests

test-rebase: conditionalize output instead of tests This should help prevent breakage like was fixed in the last patch.

tests: stabilize on Windows I'm not sure if the difference on Windows for test-sparse.t is expected or not. It looks like unless the leading '/' is followed by a drive letter, '/' is resolved to 'C:/MinGW/msys/1.0'. But both cases abort with "not under root" instead of just warning.

revset: make repo.anyrevs accept customized alias override (API) Previously repo.anyrevs only expand aliases in [revsetalias] config. This patch makes it more flexible to accept a customized dict defining aliases without having to couple with ui. revsetlang.expandaliases now has the signature (tree, aliases, warn=None) which is more consistent with templater.expandaliases. revsetlang.py is now free from "ui", which seems to be a good thing.

tests: quote $PYTHON for Windows When unquoted, MSYS sees the colon between the drive letter and path as a Unix path separator and unhelpfully splits on it, feeding only the drive letter as the command. Much chaos ensues. I vaguely remember trying to get the test runner to use /letter/path/to/exe syntax the last time this happened, without success. I doubt a check-code rule would work, since sometimes it is quoted, and sometimes the quotes are escaped.

amend: use scmutil.cleanupnodes (BC) This is marked as BC because the strip backup file name has changed.

rebase: remove "if True" The "if True" block was to make the last patch easier to review. This patch removes "if True" and unindents the block.

rebase: use scmutil.cleanupnodes (issue5606) (BC) 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 (aa4a1672583e) 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.

scmutil: make cleanupnodes delete divergent bookmarks cleanupnodes takes care of bookmark movement, and bookmark movement could cause bookmark divergent resolution as a side effect. This patch adds such bookmark divergent resolution logic so future rebase migration will be easier. The revset is carefully written to be equivalent to what rebase does today. Although I think it might make sense to remove divergent bookmarks more aggressively, for example: F book@1 | E book@2 | | D book | | | C |/ B book@3 | A When rebase -s C -d E, "book@1" will be removed, "book@3" will be kept, and the end result is: D book | C | F | E book@2 (?) | B book@3 | A The question is should we keep book@2? The current logic keeps it. If we choose not to (makes some sense to me), the "deleterevs" revset could be simplified to "newnode % oldnode". For now, I just make it compatible with the existing behavior. If we want to make the "deleterevs" revset simpler, we can always do it in the future.

scmutil: make cleanupnodes handle filtered node In some valid usecases, the "mapping" received by scmutil.cleanupnodes have filtered nodes. Use unfiltered repo to access them correctly. The added test case will fail with the old cleanupnodes code. This is important to migrate histedit to use the cleanupnodes API.

configitems: add alias support in config Aliases define optional alternatives to existing options. For example the old option ui.user was deprecated and replaced by ui.username. With this mechanism, it's even possible to create an alias to an option in a different section. Add ui.user as alias to ui.username as an example of this concept. The old alternates principle in ui.config is removed as it was used only for this option.

hgweb: use ui._unset to prevent a warning in configitems

dispatch: fix typo suggestion for disabled extension If the matching command lives in an in-tree extension (which is all we scan for), and the user has disabled that extension with "extensions.<name>=!", we were not finding it, because the path in _disabledextensions was the empty string. If the user had set "extensions.<name>=!<valid path>" it would work, so it seems like just a mistake that it didn't work.

tests: add tests for typoed commands This includes one test showing how disabling a command with e.g. "extensions.rebase=!" results in the command not being suggested. We'll fix that next.

sparse: inline signature cache clearing It is a trivial one-liner. No need to have a separate function.

sparse: move working directory refreshing into core This is a pretty straightforward move of the code. I converted the "force" argument to a keyword argument. Like other recent changes, this code is tightly coupled with working directory update code in merge.py. I suspect the code will become more tightly coupled over time, possibly even moved to merge.py. For now, let's get the code in core.

sparse: refactor update actions filtering and call from core merge.calculateupdates() now filters the update actions through sparse by default. The filtering no-ops if sparse isn't enabled or no sparse config is defined. The function has been refactored to behave more like a filter instead of a wrapper of merge.calculateupdates(). We should arguably take sparse into account earlier in merge.calculateupdates(). This patch preserves the old behavior of applying sparse at the end of update calculation, which is the simplest and safest approach.

sparse: move update action filtering into core This is a relatively straight port of the function. It is pretty large. So refactoring will be postponed to a subsequent commit.
