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.

readme: updateing changelog We forgot a couple of recent improvement.

Added tag 5.2.1 for changeset c15d6168412f

prepare version 5.1.2

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.

split: mark the command as experimental It has a bit too many rough edge for now.

tests: run test with 3.6 and apply test change Tested with 3.4, 3.5 and 3.6. Some minor test update had to be done.

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.

next: properly report no children when --evolve is used If no aspiring children exist, 'hg next --evolve' should properly issue an error message instead of crashing.

inhibit: do not search for visible obsolete changeset during stripping Stripping use transaction in an unorthodox way. We should not run the inhibit postclose hooks as it can lead to crash.

split: handle bookmarks instead of leaving them on precursor Before this patch we were leaving the bookmarks on the precursor of the split instead of moving them on the tip of the split chain. We add a test to verify the behavior.

split: don't update before it is actually needed Before this patch, we were updating the working copy parent needlessly and before the error checking. This patch fixes the issue.

split: add more output to the test Before this patch, we were not displaying the final graph resulting from the tests but just the obsolscencence markers. This patch adds more output to the test to make it more descriptive.

split: fix commit message numbering error in the test Before this patch, the test was wrong and the successors of a splitted commits all had the same commit messages. This patch makes the test right making sure that the numbering of the split successors is accurate.

evolve: handle split commit for instability

test-inhibit: simplify push destinations for Windows This was aborting because $pwd is expanding to 'C:/path/to/tests': - pushing to file://$TESTTMP/inhibit2 - abort: hidden revision '003a4735afde'! - (use --hidden to access hidden revisions) + abort: file:// URLs can only refer to localhost

test-sharing: fix globs for Windows

inhibit: don't abort when directaccess is not enabled When directaccess is not enabled, we should just print a warning and not set up inhibit. We don't need to abort in that case. Example: if the user is running hg showconfig, we don't want to crash as the command is unrelated to inhibit.

inhibit: add missing locking in wrapper for obsmarker creation The develwarning for transaction without lock rightfully pointed out to this issue. Before this patch we were not locking in the transaction for obsmarker creation and therefore showing the warnings.

evolve: (issue4386) cleanup, split, fold and bijection in `hg prune` Before this patch, the prune command was splitting and folding implicitely based on the number of successors and precursors. This patch makes the two behavior explicit by requesting a flag to perform a split or a fold.

evolve: fix typo in fold docstring

evolve: remove trailing spaces

evolve: dedupe divergents when running evolve --all --any or evolve --rev Before this patch, when running evolve --all --any or evolve --rev with the --divergent flag, we were selecting all of the divergents. After solving the first one, its counterparts would get pruned and potentially hidden which would crash when trying to resolve them. This patch introduces logic to dedupe the divergents to be resolved by keeping only one per group of divergent with the lower revision number.

evolve: remove unused warning message in _solvedivergent Before this patch, we were checking for a case where a divergent changeset could be public and printing a warning in that case. When we compute the divergent set in the obsolete module we explicitely look for not public() changesets. This patch removes this unused warning.

compat: use svfs instead of sopener The "new" attribute is about 2 years old so let's move on.

fold: avoid using x:y in the help Suggesting "x:y" is a bad idea because x:y is a very deceptive revset.

evolve: improve the help of the fold command The help of the fold command needed a little rework. This patch makes it a little less verbose and adds an example. It also highlights a little more the importance of the --exact flag.

next: add a --evolve option When on a topological head, this option will trigger the evolution of a unstable changeset that will result in a children of the current working copy parent. This should ease stacked changesets workflow by allowing to stick to prev and next to move through a stack of diff, evolving part of it on demand when needed. In case of ambiguity, the command will ask the user to choose. We need a better definition of "the stack of changesets I'm working on" to be able to seamlessly handling branching.

next: print some message when on a head with some aspiring children Being on a head does not necessary means that this is the end of the road. It is likely that some changesets could be evolve as children. We detect this case and provide a hint.

next: reword error output We move to a more compact and direct phrasing. I'm not fully happy about it yet, but this is a step forward. The listing of candidate should maybe be moved behind a --verbose flag (and such verbose flag be suggested in the error). G: changed tests/test-prev-next.t

next: refactor the command code We make the conditional flatter and the return more straight forward. This will make addition of more complex cases more straightforward in future changesets.

next: add extensive testing to the 'next' command We are going to introduce more complexity to it. We add the full extend of the case we want tested to see how they evolve later.

evolve: mechanism to load some commands selectively This patch introduces a new config option: experimental.evolutioncommands to load evolve's command selectively. It is part of a sequence of patches to make evolve's command respect the value of experimental.evolution. Once these commands are ready and actually respect the flag, they are safe to use and can be enabled with the mechanism developed in this patch.

Added tag 5.1.5 for changeset 1377f6a7f9ec

prepare version 5.1.5

evolve: non recursive implementation for _aspiringdescendants We switch from a N squared recursive implementation for _aspiringdescendants to a more efficient algorithm in O(len(unstable)).

evolve: distinct between '--all' and '--all --any' Before this patch, evolve --all implied evolve --all --any. With this patch evolve --all evolves all the aspiring descendants of the parent of the working copy. evolve --all --any does what evolve --all did before: evolving all the troubles in the repo. We add anew function _aspiringdescendant for this purpose

rework refactor _aspiringchildren by introducing _possibledestination This allows us to reuse some of the logic for evolve from _aspiringchildren for the new implementation of evolve --all. The logic is also better as some previously selected changesets may not actually evolve on the target, and some changesets that does not would not.

evolve: consider all potential candidates on bare evolve Instead of stopping at the first resolution, we returns all matches. If there is ambiguity, we abort. The function itself seems fairly flawed but will do the job in simple case.

evolve: fix an issue in the documentation of the evolve function hg evolve is solving troubles that will become children of the parent of the working copy and its descendant. This last part was omitted by mistake from the help message before.

evolve: fix error in builddependencies When MultipleSuccessorsError was raised, we were still running the code below to add the dependency if succ was not None from a previous iteration. This bug was harmless because dependencies and rdependencies are sets but it makes the code clearer this way.

test-evolve-bumped: add new test case for merge Before this patch we were not testing our warning message for bumped changesets that are the product of a merge. This patch adds a test case for that.

test-evolve-bumped: improve tests legibility This patch introduces in test-evolve-bumped some of the test helpers that we use in other tests to make the code more legible.

evolve: drop len comparison in prune and fold Computing the length of a smartest may be significantly more expensive than computing it length.

evolve: remove _picknexttroubled It was not used anymore

evolve: warn about every skipped evolution When we could not evolve a revision, we used to silently ignore it. We now inform the user that we ignored something and tell him why (with more or less informative message).

evolve: some style fix

evolve: unify revision handling and rework error message This changesets do a massive refactoring of the way evolve select changesets to be evolve. We now use a two stages approach: 1) read command line argument and produce a list of revision to evolve. 2) evolve all these revisions. This allow a much cleaner, robust and extensible code. In the process the error message issued when there is nothing to evolve have been updated to informs about other troubles in the repository and point at useful option to solve them. The 'update' case is handled independently at the start of the function.

evolve: move the 'update' if '.' is obsolete earlier A big refactoring of the computation of the revision to evolve is coming. This case won't be handled by it, so we extract it earlier.

evolve: skip unstable changesets with multiple successorssets We were previously crashing when encountering them, but we want to be able to solve the other solvable troubles instead of stopping right there.

evolve: allow multiple --rev argument This is standard behavior for Mercurial commands.

test-evolve: fix tests failing on some platform We change from echo to printf to print newlines so that evolve's tests work cross-platforms.

evolve: prevent using --rev and --any together Before this patch it was possible to use evolve --rev --any and it meant evolve --rev. This patch throws an error when using evolve --rev --any.

evolve: add selector for trouble types This patch adds command line flags to select the kind of troubles to solve. Before this patch evolve was solving any kind of troubled. With this patch evolve --all and evolve --rev can be configured to only solve only some type of troubles (divergent, bumped or unstable). To give this choice to the user we add three new command line flags to the evolve command: --bumped, --divergent and --unstable.

evolve: refresh the documentation Multiple behavior change are coming, a perfect timing to refresh the doc before we rework it more.

evolve: check for uncommited change earlier Before this patch we were checking for uncommited change multiple times and quite late for uncommited change. This patch moves the check at the beginning of the evolve method to avoid these shortcomings.

directaccess: remove import from the no warning list removal of the list previously failed for some reason.

directaccess: add some commands to the directaccess list Before this patch we had a limited list of commands in the directaccess list. This patch adds about 20 commands to that list: - all the read-only commands in core supporting a rev as an argument - 'outgoing': since people can use 'outgoing' to know what is going to be pushed, the output of hg outgoing should be consistent with to the output of hg push and must therefore disallow directaccess since hg push forbids it.

evolve: move test for evolve --rev ordering in a separate file evolve --rev reordering is a complicated enough topic to justify a separate test.

evolve: properly evolve stacked unstable with --rev Before this patch, _singlesuccessor was not returning a revision number for the case where the parent of the argument was not obsolete. This resulted in bug when testing membership with the set of revisions. This patch fixes it and adds a test.

directaccess: disable directaccess for push and serve Before this patch, push and serve were subject to directaccess. This patch makes them throw error when trying to access hidden hashes.

directaccess: change rule from opt-in to opt-out Before this patch we would opt-in commands for direct access and the default filter for new repository was 'visible'. With this patch, the default filter for new repos is 'visible-directaccess-warn'. It means that by default all the commands have directaccess with warnings.

inhibit: move transaction wrapping outside of repo setup Before this patch, transaction wrapping code was done in reposetup. It happened to cause stackoverflows in repos with a lot of subreps. This patch moves the wrapping to extsetup and avoids this problem.

tests: ignores other core output in capability testing This will avoid breaking the test anytime core changes.

evolve: make uncommit respect allowunsable Before this patch, the uncommit command was performing the same way regardless of the value of experimental.evolution. With this patch if the configuration does not allow unstability, uncommit won't create instability.

directaccess: use cached filteredrevs Before this patch we were calling directly repoview.computehidden(repo) to compute the revisions visible with direct access, without going through the caching mechanism for the filtered revisions. There was two issues with that: (1) Performance: We were not leverating the cached values of the 'visible' revs (2) Stability: If there were to be a cache inconsistency with the computation of 'visible' we would crash in the branchmap consistency check partial.validfor. Consider the scenario of rebase with bookmarks: - when we delete a bookmark on an obsolete changeset (like what rebase does when moving the bookmark after rebasing the changesets) - then this changes the value returned by repoview.computehidden(repo) as bookmarks are used as dynamic blockers in repoview.computehidden(repo) - as of now, we don't invalidate the cache in the case of bookmark change - if we have a cached value from before the bookmark change, repoview.filterrevs(repo, 'visible') considers the cached value correct and returns something different than repoview.computehidden(repo) - in turn, if we use repoview.computehidden(repo) in directaccess, the subset relationship is broken and the cache consistency assertion (parial.validfor) fails if branchmap.updatecache is called in this time window This patch leverages the caching infrastructure in place to speed up the computation of the filteredrevs for visible-directaccess-nowarn and visible-directaccess-warn. Incidentally it prevents the bug discussed in (2) from crashing when running a rebase with a bookmark. Note that there still needs to be a fix in core for the case discussed in (2). The test for this side of the fix (not core's fix for (2) is very hard to implement without introducing a lot of dependencies and does not belong here. It is much easier to have the test of the fix for the scenario (2) in core along with the fix.

inhibit: improve performance of transaction wrapping Before this patch, transaction wrapping was the most expensive part of inhibit computation wise. This patch changes the revset that we use in the transaction wrapping to make it ~50x faster to compute: revset #0: obsolete() - hidden() 0) wall 0.000214 comb 0.000000 user 0.000000 sys 0.000000 (best of 11209) vs revset #0: (not hidden()) and obsolete() 0) wall 0.010965 comb 0.010000 user 0.010000 sys 0.000000 (best of 237)

evolve: extract the code computing dependencies in a separate function The code to compute dependencies between unstable changeset can be reused to compute the next reveset. This patch extracts it in its own function to make it reusable.

directaccess: add mechanism to load directaccess after some other extensions directaccess needs to load after some extensions to avoid interfering with them. This patch adds a mechanism to specify what extension directaccess needs to load after.

evolve: add another test for evolve --rev This patch adds one test for three conditions not covered before: - evolve --rev on a stack with obsolete commits without successors - evolve --rev on two sets of stacks in parallel - evolve --rev on a set of stack partially solvable (because all of the commits of the stack are not specified with --rev)

evolve: add a more complex test for evolve --rev The previous tests of evolve --rev would have passed with an ordering of revs by increasing revision numbers. This patch adds a test that would fail if that was what we were doing and therefore tests the implementation better.

evolve: add ordering of the revisions for evolve --rev When running evolve --rev we want to process the revisions in an optimal fashion to solve the maximum amount of trouble in the minimum number of steps. This patch adds a step to evolve --rev to order the revision before solving the troubles. A simple test is added to cover a basic case.

test: adapt to change in mercurial core Bundle2 is one by default and more capability have been added.

evolve: add directaccess to the setup.py directaccess was missing from the list so that when we were building evolve it was not contained in the build.

evolve: don't crash on singled out revisions Before this patch, we were crashing on unsolvable revisions when using evolve --rev. This patch removes the crash and prints a warning when we encounter such revision.

test: adapt test to less frequent branch warning The 701df761aa94 changeset in mercurial core made the branch warning issue only for the first branch created. We adapt the tests to reflect this change.

tests: adapt summary output to 6084926366b9 The 'summary' commands recently gained phases related output, 6084926366b9 put it into a "final" state. We adapt the test to this new style.

evolve: small refactoring of the uncommit function We introduce a new variable to simplify the implementation of hg uncommit --interactive.
