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.

inhibit: fix compatibility with changes in rebase Because we compute the obsolete revisions before calling _computeobsoletenotrebased lifting the inhibition stopped working since 8a8ee8338e6 in core. This patch makes it work again.

inhibit: fix _filterpublic Before this patch, _filterpublic would always filter rep._obsinhibit and not its "nodes" argument. Fortunately, we always called it with repo._obsinhibit as its "nodes" argument!

debian: blacklist test-inhibit.t Since we don't add inhibit to the debian packages, let's not run test-inhibit.t

prune: changing bookmark argument to be a list Currently prune works with a single bookmark the changes in this patch modifies the prune command to accept a list of bookmarks Also changes to inhibit module which internally calls the cmdprune function. the change is to wrap the bookmark input into a list.

evolve: renaming local variables Renaming local variables to be more precise, i want to store a different list of bookmarks(input-list) and it would be hard to understand what marks represents in that change therefore renaming it to repomarks. Renames mark to bookmark, which will make the changes in next patch more understandable, when it is pluraized. Also renames bookmarks (module) to bookmarksmod so as to free up the name when bookmark gets pluralized.

evolve: fix test-inhibit to match latest hg When I fixed an issue in core about rebaseset 40a2f972f26d (that I introduced before), it restored the original behavior of inhibit with rebase. This patch fixes test-inhibit to match the latest hg.

evolve: fix test-tutorial.t to match new extra computation in core Recent patches changed the way we compute extras for rebase and graft. This changes the hashes in evolve's tests. This patch fixes the test test-tutorial.t

inhibit: make rebase see obsolescence even for visible nodes Rebase changed recently to take advantage of obsolescence markers to reduce the number of conflicts to resolve. Inhibit users were unable to leverage this new feature because none of their visible nodes could be obsolete. This patch makes the nodes that would be obsolete without inhibit, actually obsolete for the duration of the rebase to take advantage of the feature mentioned before.

inhibit: remove unused bookmark operation wrapping Before this patch, inhibit was wrapping bookmarks.write and bookmarks.recordchange. Since all the usage of bookmarks.write are not replaced by bookmarks.recordchange all bookmarks operation happen in a transaction. Inhibit already wraps the transaction mechanism to make sure that no revision can end up being obsolete and visible. This makes the wrapping of bookmarks.write superfluous. Wrapping bookmarks.recordchange was wrong in the first place and redundant with wrapping transactions.

inhibit: update test with new behavior from core The recent changes in core (to make sure that all bookmarks write are done at the end of a transaction) changed the behavior of inhibit. When one rebases a set of hidden revs somewhere, the hidden revs become visible at the end of the rebase. Both the previous behavior and new behavior seems acceptable but the tests have to be changed subsequently. This patch modifies one of the test for inhibit when the case mentioned above happens. We prune the revs inhibited by the rebase to make the change minimal.

inhibit: remove unused import The error module from mercurial was imported but unused in the inhibit code.

inhibit: improve handling of error cases for bookmark -D Before this patch bookmark -D was crashing in some cases like: hg book -Dmaster-fix. This was because -m is a valid option for hg bookmark. This patch disallows using -m with -D (moving and pruning does not make much sense) and throws an error instead of crashing if the command is malformed.

directaccess: fix case of shortened hash containing only digits For directaccess, there are four cases for what looks like short hashes made of digits only: 1 | the hash is a revision number and not a short hash for another revision: we don't change the visibility 2 | the hash is a revision number and a short hash for another revision: we don't change the visibility 3 | the hash is not a revision number and not a short hash for another revision: we don't change the visibility 4 | the hash is not a revision number but is a short hash for another revision: we make it visible Before the patch we were not lifting visibility in case number 4. This patch fixes the issue.

evolve: evolve --divergent failed when merge had nothing to do (issue4950) Before this patch, if the divergence resolution lead to an empty commit, the transaction would be rolled back and the divergence not resolved. This patch allows empty commits in that case. It is legitimate to end up with an empty commit in that case, for example when divergent commits differ over their commit messages.

inhibit: use dirty revset trick to speedup the inhibit search space. See documentation for details. I'm a bit sad about this changesets.

inhibit: use 'repo.revs' instead of 'repo.set' This skip the creation of a changectx object.

_inhibitmarkers: turn the result from generator into a list A generator object is always True, we have to turn it into a list in order to be able to use it in the tests. Before this patch we were rewriting the 'obsinhibit' file all the time, this had a performance impact especially on repository where transaction are expensive (hooks, cache invalidation, etc). Writing this file less often have a minor effect on test where a stripped changeset does not get removed from the obsinhibit file is still inhibited when unbundled back. I think this is fine and I'm moving forward.

split: drop the experimental flag I've been using it without issue for some time. The only blocker in my mind was the lack of commit message preservation and this is now fixed.

split: preserve original changesets description Losing the description on split is to much an issue, we offer the original description to edition for every part of the split.

merge with default there is some 3.6 related fix and test change that we need on default. No other significant change happened since last release expect for split, still marked experimental. So we prepare for a bugfix release.

prune: have dirstate collaborate with transaction With 3.6, dirstate update can work with transaction to ensure proper rollback. We do it if the mercurial version permit it.

evolve: have dirstate collaborate with transaction With 3.6, dirstate update can work with transaction to ensure proper rollback. We do it if the mercurial version permit it.

prune: reuse revset from repair instead of copy-pasting code

merge with stable

evolve: compatibility with coming 3.6 Some function in the import stack changed, we have to adapt.

evolve: be more complete about copying extra from old revisions For 'hg evolve' we want to copy all extra-level metadata except for branch. This keeps the experimental topics extension from getting obliterated by evolve runs. Many hashes in tests changed due to some extra data coming along for the ride in various places, but no functionality that was tested. It's plausible that this copies too much metadata - maybe we should be dropping rebase_src or convert_revision as well. Right now no tools do that, so I'm biasing towards preserving everything except branch when copying metadata for now.

evolve: ignore ui argument passed to help loader The API changed at Mercurial e0c572d4d112.

directaccess: inspect trees of len() > 3 Previously, when inspecting revset AST's we'd only traverse down the tree if it was length 3 ([op, left, right]). In some situations, like 'or' the tree node will be greater than length 3 ([op, first, second, ..., nth]). So we need to traverse all the parts of the node to catch all the symbols.

debugobsconvert: make sure obsstore is loaded before version comparison hg 44918682093f delays loading obsstore, so we have to access _all to get the correct store version.

evolve: use repo._bookmarks.recordchange instead of repo._bookmarks.write We want to get rid of the api repo._bookmarks.write and this patch removes its use in evolve.py. Before this patch, we were using repo._bookmarks.write to save bookmarks change immediately instead of repo._bookmarks.recordchange that write change when transaction ends.

evolve: indentation change for making next patch more legible In the next patch: "evolve: use repo._bookmarks.recordchange instead of repo._bookmarks.write" we need to add a transaction in the rewrite function. To do so adds an indentation level and makes the patch harder to review. This patch makes the indentation change so that the next patch is easier to review.

inhibit: fix inhibit working with non-inhibit repos Inhibit was breaking when two repos were in memory, but one was not an inhibit repo (like when doing a local pull between two repos). The fix is to add inhibitenabled checks to all the places where inhibit does global wrapping of commands (every code path from the extsetup wrappers).

directaccess: don't try to partialmatch things that aren't hashes Trying to partialmatch identifiers like '.' turns out to be (a) pointless and (b) extremely slow. On a repo with a million commits, with directaccess enabled, hg log -r .^::. goes from 2.1 seconds to 0.5.
