Added tag 5.4.0 for changeset b21ce82e6f76

evolve: prepare release of version 5.4.0

evolve: update testedwith field 3.8.1 is working fine and no older branch had to be dropped.

merge with stable through 3.5 branch

test: wider glob for payload size For some reason this various a bit more than previously though.

merge with stable throug 3.6 branch

merge with stable through 3.7 branch dropped the topic test and updated output with some minor difference Hg: Enter commit message. Lines beginning with 'HG:' are removed.

mercurial-3.7: revert output change No feature regression but various output change

merge default into stable Mercurial 3.8 have been release, let's get ready for a 5.4.0 release.

test: rename TOPICROOT to HGTEST_TOPICROOT Mercurial is about to introduce whitelisting of environment variable, we comply to the planned prefix in advance in a hope to stay compatible in the future.

test: update topic test output for order change As in topic d8f1e432b16a the tipmost changeset is now displayed first. We adapt the test output to reflect it.

test: update topic test output for indexing change Changeset 61f36480740f in topic updated the indexing scheme, we update the test to take this into account.

test: adapt topic test The 'created new head' bug was fixed in bdc5bb223b50, we adapt the test with the fixed output.

test: improve skipped message for topic The skipped message should point people to a way to solve the situation.

prune: suggest --biject in error "hint" When use specify multiple changesets to prune and as successors, we should point them to the right options to confirm there intend.

metaedit: check for public changeset before instability Public changeset will stay public even if the selection is adjusted, this is a more definitive condition that is worth warning about first.

fold: move sanity check after locking Checking for operation validaty without the locks open us to race condition.

metaedit: add support for folding commits while editing their metadata This also allows us to accept multiple commits without dealing with the thorny algorithmic and UI issues of editing multiple commits at once. Crucially, it is different from 'hg fold --exact' in that it also allows 'folding' a single commit and rewriting its metadata. This is really useful to have as a single logical operation, for example while preparing a series of multiple local changesets that will need to be pushed as a single changeset.

commands: introduce a new command to edit commit metadata This patch introduces metaedit, a command to metadata of a set of revisions without updating the working copy. This is particularly relevant for repositories where changing the parent of the working copy is time-consuming. We could add more stack manipulation operations to metaedit in the future.

evolve: factor out check for creating unstable commits This check is pretty non-trivial, and we do it in two places already. We're going to do it in a third place soon.

evolve: factor out sanity checks for folds We're going to use the same checks in another context in an upcoming patch.

evolve: include node, rev, desc, and phase in list

evolve: use hex in list output

py3: use items() instead of iteritems()

py3: change except from two comma to as notation

py3: tolerate io/StringIO divergence

split: rewrite the pre-split commit message I find this wording slightly clearer.

open mercurial-3.7 compat branch

readme: add various missing parts

hgignore: add an ignore rule for test timing Modern tests runner store a record of last test run timing. We properly ignore it.

tests: change quoting pattern to match core's conventions This patch modifies two tests to match new quoting patterns used in core: (use "hg config --edit" to set your username) becomes (use 'hg config --edit' to set your username) and (use hg resolve and hg graft --continue) becomes (use 'hg resolve' and 'hg graft --continue')

evolve: Fix crash when reading docstring Before this patch, hg evolve --divergent could crash when looking for docstring of function of merge.update. We were checking the docstring to work properly with older version of Mercurial. It could crash if an extension would wrap merge.update without keeping the docstring. This patch fixes the crash.

prune: remove the kill alias This have been a long time since the command was rename (over 'kill -1' threat), it is time to get rid of it.

topic: restrict 'hg prev' to current topic unless --no-topic is passed This is far from perfect but a good start

topic: restrict 'hg prev' to current topic unless --no-topic is passed This is far from perfect but a good start.

topic: preserve topic during evolve previously, topic handling was absent leading to whatever the active topic was when `hg evolve` was run to be used for all evolve results

topic: 'hg evolve --all' pick all trouble within current topic This is the first changeset of a collaboration between the topic extensions and evolve. If there is an active topic, 'hg evolve --all' will try to fix all changesets in that topic wherever they are. Aspiring descendant that are not in the current topic will be ignored. For now, evolve behave as usual if there is no active topic. This is a bit inconsistent and will probably be unified in the future.

close branch 3.3 I'm not expecting any more work in there.

evolve: mark progress units for translation

evolve: ui.progress doesn't use total count if pos is None, let's drop it Every other call of ui.progress that has argument #2 (named `pos`) set to None doesn't specify `total`, because it won't be used. Basically, ui.progress(action, None) is enough, when used like this it hides progress bar because the action is considered completed. So this is just a minor cleanup patch.

debugrecordpruneparents: fix an apparent typo (marks)

test: explicitly disable rebaseskipobsolete in a couple of place (issue5135) We want to keep the old behavior for the sake of testing.

evolve: remove unused import

hgext: turn 'hgext' into a namespace package Actually since Python 2.3, there is some way to turn top level package into "namespace package" so that multiple subpackage installed in different part of the path can still be imported transparently. This feature was previously thought (at least by myself) to be only provided by some setuptool black magic. Turning hgext into such namespace package allows third extensions to install themselves inside the "hgext" namespace package to avoid polluting the global python module namespace. They will now be able to do so without making it a pain to use a Mercurial "installed" in a different way/location than these extensions.

evolve: make split respect rev args passed without --rev or -r Currently, if one runs `hg split .` or `hg split`, it will fail with an exception. This happens becuase we only expect revision args to be passed as --rev/-r ones and don't treat unnamed args properly or add default values if no args are provided.

evolve: write our own custom evolvestate file Since for ever, we were using 'graftstate' to record the node currently being evolve and allow 'hg evolve --continue' we now move to our on 'evolvestate' file. This remove and issue with 'hg summary' listing interrupted evolve as graft. This also open the way for storing more data into that file and allow proper --abort and --continue of the whole evolve operation (and not just the last one). The whole thing is very hacky but at least there is some progress. Thanks goes to Shusen Liu for initiating this work.

readme: update readme for issue 4966

test: back hash change from 'extra' content change out The changesets 13701c3fed9c, 3e907ff1981f and 54394d2aaf5e were introduced to handle a change to the way extra were carried out by various command in core. This had to be backout for 3.7.1 as is broken multiple third party extension. We backout the test update as a result. Core changesets performing the backout: ce9696193175::b698abf971e7

evolve: close transaction if conflict is detected in relocate (issue4966) Before this patch, transaction is aborted, if conflict is detected at merging while "hg evolve". Since 8f2ff40fe9c9 (or 3.6) of Mercurial, aborting transaction discards all dirstate changes inside transaction scope for "transactional dirstate" (see below wiki page for detail about it). https://mercurial.selenic.com/wiki/DirstateTransactionPlan Therefore, just aborting transaction causes unchanged (and unexpected) dirstate, even though subsequent commands require dirstate changes while "hg evolve". To keep dirstate changes while "hg evolve", this patch closes current running transaction, if conflict is detected in relocate(), even though exception is raised as usual. Even though "save dirstate and restore it after aborting transaction" like shelve._aborttransaction() of Mercurial can also solve this issue, this patch chose closing transaction for similarity with failure for conflict at "hg unshelve". In addition to it, closing transaction can keep any previous (implicit) changes. In newly added test, there is an additional ancestor revision, which "will be evolved safely". It is used to examine whether failure for conflict doesn't discard already relocated revision(s) while "hg evolve". It is fact for current implementation that "hg evolve" relocates each revisions in separated transactions and already relocated ones are never discarded, even if subsequent relocation fails. Though, this examination is useful to detect unintentional regression in the future.

evolve: remove meaningless transaction nesting Before this patch, functions below nest transaction scope, even though they are invoked only inside a transaction scope created at _solveone(). - _solvebumped() - _solvedivergent() - relocate() via _solveunstable() or _solvebumped() Transaction nesting is useful for localizing "success" (e.g. one scope per commit inside wider scope for multiple committing). But such nesting is redundant for _solveone(), because there is no code path, which causes failure after successfully closing inner transaction(s). In addition to it, this nesting makes it complicated to close current transaction successfully with exception raising inside inner scope, like "hg shelve" at detection of conflicts. "tr.close()" is required at each outer scopes for such case. To remove meaningless transaction nesting, this patch replaces repo.transaction() in functions above by repo.currenttransaction(). This reuses transaction created at _solveone(). This patch also adds 'assert tr' after getting current running transaction, to avoid invocation of functions above without transaction.

evolve: extract logic to new method _evolvemerge This patch introduces a new method _evolvemerge to merge orig to dest in relocate method. This simplifies the code of the method relocate and allows us to re-use it later in the scope of the rework of 'hg evolve --continue'

test: add extra expected output (I forgot to amend...)

inhibit: make bookmark -D work with a list of bookmarks `hg bookmark -D` was not accepting a list of bookmarks. This behavior was inconsistent with the behavior of `hg bookmark -d`, which does accept multiple bookmarks.

touch: prompt the user for what to do with the revived changeset This patch improves our interface for reviving changesets. This patch makes touch not assume that the user wants to create divergence by default and gives a prompt instead. The prompt is skipped for changeset that have no living successor as no divergence would be created by reviving them anyway. To restore the previous behavior, one should now use the --allowdivergence flag. The prompt looks like: [10] <description> reviving this changeset will create divergence unless you make a duplicate. (a)llow divergence or (d)uplicate the changeset? a In further patches we will want to add one more choice to that prompt, for example having a marker between the old and revived nodes but no divergence displayed on the UI.

inhibit: fix compat with rebaseskipobsolete We wrap _computeobsoletenotrebased and _clearrebased to fix the following case: - Assuming that we have markers from revisions of the rebase set and destination set and that these markers are inhibited - At the end of the rebase the nodes are still visible because rebase operate without inhibition and skip these nodes Had we not have those markers to begin with the revisions could be hidden at the end of the rebase. We keep track in repo._obsoletenotrebased of the obsolete commits skipped by the rebase and lift the inhibition at the end of the rebase. We add three test cases to make sure that the edge cases are covered.

test: update with new graft output Graft now has a --continue it seems. We need to update our test output.
