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.

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.

prune: remove a list of bookmarks Currently prune works with a single bookmark, the changes in this patch modifies the prune module to work with a list of bookmarks Building on this we can take a list of bookmarks as input and remove all of them in a single go

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.

inhibit: backout 23a34dce5131 remove unused bookmark operation wrapping This breaks potentially a lot of things. Let's give a change to extensions maintainers to adapt to the new bookmarks.write api before removing this code right away.

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.

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.

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.

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.

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.

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.

evolve: make sure we use an unfiltered repo when looking for divergence data Let's be double sure

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.

evolve: improve error message We add a new line and change the wording from 'revsets' to 'revisions'.

evolve: move return statement at the right level When no trouble was found with the --rev option, the code of the evolve function would continue running and would solve unwanted troubles. This patch makes sure it does not happen.

evolve: remove extra whitespace This patch removes a whitespace at the end of a line.

directaccess: don't crash when evolve is not loaded Before this patch, when evolve was not loaded direct access was crashing. This patch catches the error and prevents the crash.

inhbit: don't crash on commit with no changes Before this patch inhibit would crash when running hg amend with no changes. This patch fixes this case and adds a test to prevent regression.

evolve: add a test for prune --keep -r . with active bookmark We recently changed the behavior of prune to make sure that the active bookmark stays active after prune -r . This patch adds a test for the case of prune --keep -r . that does not take the same code path.

Merge with stable

inhibit: add test to ensure that --hidden is working with inhibit There was a concern with the transaction hook in inhibit and its potentially devastating effect when used with --hidden. The transaction hook in inhibit hides all the visible & obsolete commits when the transaction ends using the visible() and the obsolete() revset. --hidden does not change the visible() revset so it is fine. If this changes in the future and --hidden actually ends up impacting the visible() revset, this test will catch it and prevent inhibit from putting inhibition markers on all of the obsolete changesets.

prune: with active bookmark should stay active hg prune with an active bookmark was deactivating the bookmark after the prune. This patch makes sure that if a bookmark was active before a "prune" operation (except prune -B) then the bookmark stays activate afterwards.

merge with stable

evolve: migrate off of now-dead util.any

inhibit: create direct access extension Since we want to use direct access without necessarily using inhibit, this patch separates both extensions. Inhibit depends on direct access and we add a test to check that it complains if that is not the case.

inhibit: handle inhibit marker on stripped revision If a revision disappear from the repo, we should not crash.

update README

evolve: don't use python sets on top of revset for evolve --rev In --rev we were wrapping the revsets in python sets. This is wrong as the use python sets force the wrapper revision set to be computed earlier than it has to and have no order guarantee. Removing this wrapping changes a test because the ordering does not appear to be the same but the end result is the same.

evolve: current bookmark wrongly moving during prune (issue4559) Before this patch: prune -r <otherbookmark> also moved the current bookmark eventhough it was not related to the pruned changes. This patch fixes it and adds a test to catch regressions.

inhibit: direct access with and without warning on a per command basis We introduce a new filtername visibile-directaccess-nowarn to enable direct access with no warning on a per command basis. The motivation behing this change is to display warning when attempting direct access in destructive commands.

inhbit: make tests work with evolution.createmarkers config Before this patch, the test for inhibit was assuming evolve fully running. For most of the features that inhbit enables, createmarkers is sufficient. This patch makes the test of inhibit run with the createmarkers config and only lifts it for operations in the middle of the stack.

inhibit: config to enable only direct access Inhibit provides several features to hide instability and direct access. We want to use direct access in evolve without hiding the instability. This patch adds a config flag to enable only direct access in inhibit, when this config flag is not set or set to false we enable all the features of inhibit that don't concern direct access.

bookmarks: update to use new bookmarks api via compatibility layer Tested against 3.4 and latest hg + upcoming bookmarks patches

simple4server: remove buggy wrapping of pull related function Not only the wrapping was all buggy, but simple4server is not supposed to affect client side pull.

simple4server: update bugtracker link We moved all evolution related bug to the core Mercurial tracker.

evolve: rename handlenotrouble to _handlenotrouble and add doc As suggested by Pierre-Yves on his comments on f113636997660b807c36cf1d0a06b76d53ada1a4 we make it clear that this function is private and explain what it does.

evolve: improve the help message of --rev User's are not exposed to the notion of revset, this patch makes the help message more intelligible.

evolve: add --rev option to the evolve command This patch is part of a series of patches to refactor the evolve method and make it more readable. We introduce a new --rev flag to specify a revset where to solve the troubles instead of looking from the parent changeset. All add a test checks that --rev works with several commits

evolve: extract cleanup logic in the evolve function We are going to need to reuse the cleanup logic when introducing --rev, so we extract it in a method to avoid code duplication.

evolve: simplify the evolve function We compute the troubles once and use it in two places instead of recomputing them just to count them.

evolve: optimize the computation of the troubled() revset We take the implementation from _counttroubles() and rely on the more efficient & operation for revset instead of laying down the entire set with %ld.

inhibit: don't inhibit pinned commits during rebase During a rebase we pin certain commits to always be visible. This caused the inhibit extension to inhibit them when a transaction closed. Let's make inhibit aware of such pins and not obsolete them.

evolve: extract the logic to solve one change into a method The goal is to later reuse this method to implement the --rev flag for evolve that solves the troubles in a revset.

evolve: add new variable and comment Add comment and introduce a new variable to keep track of if the progress ui is shown. Later on we will use this variable in the implementation of the --rev option.

evolve: move code to track progress and start node This makes it easier to refactor the evolve function in this serie of patches.

evolve: renaming of a variable tro was not a really descriptive name, replacing it with nexttrouble.

evolve: refactoring of the code displaying error when no trouble found Before this patch, we had many return statements in the evolve function especially in the part in charge of displaying errors when no troubles were found. We move this code in a separate function.

evolve: refactor code computing stats of obsolescence markers Duplicated code removal by extracting a function.

evolve: refactoring of code related to pushing obs markers This removes duplicated code for the pushobsmarkers logic

evolve: improve transaction related code to use the lock module Refactored some of the places where we are using locking in evolve to use the lock module and write less code. This should also fix a couple of bug where tr could be None at release time.

test-inhibit: test bookmark -D without prune enabled The --config option were dropped for lack of documentation.

inhibit: fix devel warning _inhibitmarkers was taking a transaction without the proper lock. Adding the lock removes the warnings.

evolve: add -i flag to amend command The -i flag was missing because it is not a global flag of the commit command. We can't make it a global flag yet as it is used in many places where it would not be appropriate so we just add it for this occurrence. Also, we only want to add it when commit supports it (otherwise it wouldn't work with older versions of mercurial)

prune: prune fix transaction pattern I forgot to amend.

prune: fix pruning w/ bookmarks and inhibit Previously prune would create the obsolesence markers, then try to fix up the bookmarks. With inhibit enabled, the act of closing a transaction for the bookmark step caused it to unhide commits that were trying to be pruned. The fix is to put the whole thing in a transaction.

inhibit: remove book -D dependency on cmdprune Bookmark -D was relying on the prune command to be registered, which isn't the case if we've disabled evolve commands. Instead, let's just hard code the arguments. The real fix would be to abstract away the 'I want to prune commits' functionality in evolve to a reusable function, but this will do for now.

inhibit: wrap repo.commit to inhibit nodes Rebase was failing if you rebased a commit, stripped it, then rebased it again. This is because the node was still hidden and we needed repo.commit to uninhibit it.

docs (sharing): more scattered wording tweaks

docs: sharing guide: clarify end-game of "Example 2" - push to dev-repo, rather than pulling into it (consistent with how we work the multiple developer scenario later) - explicitly demonstrate that public changesets are immutable

docs: minor tweaks to sharing guide (suggested by timeless)

docs: add code review scenario to sharing guide The idea is to demonstrate a simpler multiple-developer situation that does not involve getting into trouble. The final scenario illustrates Alice and Bob getting into trouble with bumped and divergent changesets by amending each other's history. The required tests and text are all written, but will need to be heavily revised because of the inserted scenario.

docs: add a bit more hierarchy to the sharing guide

docs: update sharing guide based (mostly) on marmoute's review - don't claim certain scenarios are more/less common, just simple/advanced - mention code review as a multiple-developer scenario (not described in detail yet!) - suggest "hg config --edit --local" instead of "cat >> .hg/hgrc" - use -q less often (and show resulting output) - edit some section headers to be consistent with user guide (example numbers; "amend" instead of "amending") (These are just the small changes; big changes are yet to come.)

discovery: port the new hashing version to simple4server

discovery: introduce a obshash1 function using fm1 during hashing (issue4587) The 'fm0' serialisation translate float to text. This give different result between python2.6 and python2.7 (because python2.7 got smarter). The 'fm1' is all binary and expected to be stable so we introduce the ability to do the discovery using hash computed with 'fm1' serialisation. We use a new wireprotocol version (Partly because I'm too lazy to check how to add an argument to the existing one) and capabilities). Support in simple4server is will come in the next changeset.

tests: use 'wget' instead of 'curl' for Windows compatibility The whole test suite now runs without skips, and the only two failures are a bookmark cache issue in test-prune.t, and a local output vs remote output reordering when pushing to ssh. The latter anyway is a core problem.

setup: allow including inhibit in the build Adds the INCLUDE_INHIBIT environment variable to allow including the inhibit extension in the build.

inhibit: Add -D option to the bookmark command The -D option for bookmark is similar to the -B option for strip. It deletes the bookmark and prunes the changes underneath it that are not reachable.

inhibit: don't leave any obsolete commit visible after closing transaction We add a callback to wrap the transaction closure to identify commits that are obsolete and visible. We inhibit them to prevent the user to see instability in the UI.

evolve: apply prune update before creating obsolescence markers Prune used to compute the destination commit to update to after creating the obsolescence markers. This is a commit to prevent a bug that would occur with the changes in inhibit for transactions (next commit). Indeed, with that change in inhibit, when creating the obsolescence markers in prune, they would get inhibited right away and we wouldn't update to the first non obsolete parent but stay on the same node as its obsolescence would have been inhibited (bug).

test-inhibit: check graph after prune We want to ensure prune keep working even with inhibit.

test-inhibit: drop trailing white space

tests: make tests work on Mac OS wc -m adds spacing before the results, we trim them to make the test pass on Mac OS.

inhibit: ensure that no obsolete changesets are visible after a bookmark change When creating a bookmark, we could reveal obsolete changesets. We are inhibiting the obsolete changesets resulting from a bookmark change. There are two ways to record bookmark changes to disk and we wrap both.

inhibit: ensure no visible changesets are obsolete after an update When updating to a commit we want to inhibit any obsolete commit affecting the changeset we are updating to. In other words we don't want any visible commit to be obsolete.

inhibit: enable direct access from parsing the revset tree To enable direct access we: - detect explicit hexadical reference to node in the revset tree - add these hashes to the static blockers to make them and their parent visible for the command to run

evolve: change config option name I forgot to amend...

config: allow disabling commands Now that upstream Mercurial has multiple options for obsolete configuration, we can allow enabling and disabling of evolve commands.

inhibit: Add some inhibition clearing mechanism We do not want to keep inhibition marker around for ever. So we are removing the one applying on public changeset.

add a 'inhibit' extension This extension will be used to reduce the scope of evolve in order to make some of its features available to the mass earlier. See extension documentation for details.

tests: use 'wget' instead of 'curl' for Windows compatibility The whole test suite now runs without skips, and the only two failures are a bookmark cache issue in test-prune.t, and a local output vs remote output reordering when pushing to ssh. The latter anyway is a core problem.

tests: import killdaemons.py from Mercurial 1cfded2fa1a9 This contains updated functionality to kill the server process on Windows, which is needed to run the test-*server.t tests. This version requires the pids to be passed as an argument instead of via $DAEMON_PIDS.

prune: add --keep to not touch the working copy In order to more closely emulate strip, lets add --keep to leave the working copy untouched when we do our prune.

strip: add the option for wrapping the strip command Adds an experimental option for wrapping the existing strip command and replacing its functionality with prune. It currently doesn't handle the --keep case, but an upcoming patch will address that.

wrapcommand: fix wrapping extensions that aren't enabled The extension command wrapping would previously fail if the extension wasn't enabled. Let's just eat that silently.

wrapcommand: allow adding additional arguments to commands This allows eh.wrapcommand to specify additional parameters to be added to the commands being wrapped. This will be useful when wrapping strip in the future.

pushexperiment: remove use of obsolete._enabled pushexperiment.py was using obsolete._enabled but it didn't cause any tests to fail so I didn't see it. Let's go ahead and replace it with the new obsolete.isenabled() api.

oldobsolete: remove use of obsolete._enabled obsolete._enabled is deprecated. Switch to the newer obsolete.isenabled() logic.

server4simple: remove use of obsolete._enabled obsolete._enabled is deprecated, so let's replace it's uses.

config: remove uses of obsolete._enabled Upstream Mercurial will be removing obsolete._enabled soon, so switch all our uses of it to use the new obsolete.isenabled(repo, option) function.

config: enable all obsolete options Upstream Mercurial has moved away from obsolete._enabled as the obsolete flag to a series of options. This patch makes evolve enable all the options automatically if the user hasn't enabled any already. This preserves the existing evolve experience of not having to configure anything.

At any rate, this code was stolen from httppeer._callpush(), where it calls self._call().

Caching encoded markers takes care of the second part and speeds up cloning in bug 4518 by about 35%.

update readme and bump version to 5.1

merge default into table 3.3 is about to be released.

discovery: filter null from the discovery revset If there is nothing in common, common will be "null" and the revset will now returns "-1" crashing the discovery process. We filter out the null revision to prevent that.

tests: update to new core output Multiple output change need to be applied to the test suite.

evolve: explicitly disable bookmark on evolve (issue4432) We no longer leave the current bookmark active after an evolve, since it is no longer pointing to the working directory.

discovery: do not build sample if undecided is smaller than sample size This prevents crash with coming change in the mercurial discovery.

merge with stable

init: don't abort Mercurial on version mismatch Evolve causes Mercurial to exit if there is a version mismatch, even if no evolve command is invoked. This is a headache for people who have to work with multiple versions of Mercurial. Instead, raise an ImportError, which gives a warning but otherwise allows Mercurial to run non-evolve commands.

Added tag 5.0.2 for changeset dbd0733e5840

prepare release 5.0.2

test: adapt to core change in graft and rebase The ouput changed we have to adapt

merge with stable

doc: drop rebase extension activation The dependency have been dropped.

evolve: remove the dependency to the rebase extension We do not use any rebase internal anymore.

evolve: remove the use of `rebase.concludenode` Half of this function is now done in `merge.graft` and the over part is easy to redo manually. So we remove the usage of this function to remove the dependency of evolve on the rebase extension.

evolve: use `merge.graft` instead of `rebasenode` The core mechanism is properly factorised and have a more stable API. This is also a good step toward removing the dependency between evolve and the rebase extension. This also avoid a breakage with the future 3.3 where some of the rebase API changed.

readme: add a reference to the bugtracker in the contribute section Idea from Patrick Mezard

merge with stable

debian: update changelog to 5.0.1

test: adapt test to stable output Stable branch should pass test with mercurial stable branch.

Added tag 5.0.1 for changeset 0f3090785283

evolve: update in file version (I'll eventually -not- forget to do so)

Added tag 5.0.1 for changeset 51e1e962172c

readme: prepare for release 5.0.1

readme: update changelog

evolve: tell user which "base of divergent changeset" is not found

debugobsconvert: fix 6f08a8f6bb1d and add proper test The changeset adding deduplication (6f08a8f6bb1d) was super buggy and dropped all obsmarkers in the repo. We update the test to check this case and fix the deduplication.

merge with stable

debugobsconvert: fix a typo on "version"

debugobsconvert: also deduplicate markers in the process Various bug allowed identical or semantically identical marker to be added to the repository. So we also filter duplicates when converting.

evolve: fix capitalization in docstring for commands

test: ensure we echo prompt Tool running using the shipped 'run-tests.py' instead of the mercurial one would get different result otherwise.

debian: blacklist simple4server tests simple4server is not part of the package.

debian: blacklist test-drop drophack.py is not shipped.

debian: update control file to reflect dependency to mercurial 3.2

evolve: fix the version number The tag is 5.0.0 the content of the file was wrong.

help: fix typo in help for 'obsolete' option added to import command

test: add an explicit test for simple4server with bundle2 This makes it more likely to we catch issue with the iteration of these two.

Make next/prev only move bookmarks optionally

obsup: hack extension to make in-place upgrading of obsolete markers easy I tried upgrading my obsstore by doing a local clone as suggested by Pierre-Yves and Sean, but that caused me to end up with a ton of unstable changes that should have been marked dead. In fact, as far as I can tell, most of the performance win of that upgrade came from the fact that only about 46% (46672 of 102285) of my markers were brought over with the copy-and-pull method.

merge stable into default

evolve: fix selection of changeset to evolve from the middle of a stack (issue4434) The evolve algorithm picked a bad changesets to evolve (unstable changeset with no obsolete parent (but unstable parent). And then get confused assuming that is the first parent was not obsolete, the second should be. This changeset fixed the issue by preventing selection of direct descendant of [.] when evolving.

merge

merge back with compat branch

create a branch compatible with mercurial between 3.0.1 and 3.1.2

evolve: fix suggested commands in "parents are not common" hint The argument to 'hg rebase' is --dest, not -dest. Also, the same command should not be suggested twice -- the second option should be the rebasing the other way around.

evolve: add missing newlines in "parents are not common" hint

test-touch: add a test for rename preservation after touch This bug was recently fixed in 3.2.

evolve: fix error during iteration over bumped changesets (bug38) We are iterating over a manifest while altering it. We cannot use iteritems() in this context. we move to items, that will be an issue for very large changesets.

evolve: add various version info to save time on troubleshooting

readme: drop the mention to the wip repo The time spend in work in progress repo are fairly low nowaday.

readme: update the contribution process The inability to easily pull from pull request on bitbucket and the lack of obsolescence support there are too much pain. Patchbombed contribution are flowing so we drop the bitbucket mention in the README.

merge 5.x line into stable (drop pre hg-3.2 compat)

evolve: add the missing newline to output messages where needed

evolve: add the missing argument to a debug statement

uncommit: abort when rev specifies the current changeset The uncommit command now fails when the rev argument indicates the current changeset. Previously this aborted in the changeset obsolescence machinery when the current commit tries to obsolete itself. Using the rev argument like this indicates a misunderstanding, so printing an uncommit-specific error should make it easier to understand what went wrong.

test-amend: add a test for amend with no configured username (issue4211)

evolve: preserve branch change evolve will now preserve branch change. If the evolved changeset had a different phases than its parent, this branch name will be preserved. This allow propagation of branch change during amend but do not overwrite special branch name on children,

amend: allow the --logfile argument to work properly Though documented to work, using --logfile previously set the message option to that of the parent commit, and cause amend to abort with this message: abort: options --message and --logfile are mutually exclusive It's not clear why the 'edit' option is popped, but this option is only fetched in order to let the core commit command do the work.

Added tag 5.0.0 for changeset c13b408c0006

setup.py: bump version to 5.0.0

evolve: update tested with statement

README: update for 5.0 release

fixup previous changesets (after forgot to amend).

prune: stop reinjecting all selected revisions back into the revrange This trigger quadratic complexity for no good reason.

test: adapt to new hidden-changeset message From c1aede895072 we have a nicer error message when accessing public changesets: abort: hidden revision '6'! (use --hidden to access hidden revisions)

pullobsolete: handle migration from todosteps to donesteps This make evolve compatible with change made in Mercurial (92bf9abc4deb)

evolve: adapt to change in core rebase Mercurial core changeset 63e889cc610d (And the ones around it) changed the way graft and rebase work. We adapt to them.

test: ignore bytes lenght in message We should be storying floating point number as floating point number. So the size of the meta for fm0 format is going to be unstable. We cover them with a glob.

evolve: adapt to the new metadata storage Metadata are not stored as a "list" of (key, value) tuple instead of a binary blob. This adapt to ef880e28e56a in Mercurial.

debugobsstorestats: drop the average meta length Does not have much sense with the existence of multiple format with different meta storage. We drop it for now and will introduce and average markers length later.

debian: remove .PHONY line completely This does not work in the case of implicit pattern matching rules as used by dh. Consider this example from Geoffrey Thomas: $ ls -l total 16 -rw-r--r-- 1 faheem faheem 17 Aug 16 20:27 blue.c -rw-r--r-- 1 faheem faheem 17 Aug 16 20:27 green.c -rw-r--r-- 1 faheem faheem 35 Aug 16 20:26 Makefile -rw-r--r-- 1 faheem faheem 17 Aug 16 20:27 red.c $ cat Makefile %: %.c gcc -o $@ $< .PHONY: blue $ make red gcc -o red red.c $ make green gcc -o green green.c $ make blue make: Nothing to be done for blue'. The Make manual (http://www.gnu.org/software/make/manual/make.html#Phony-Targets) says Since it knows that phony targets do not name actual files that could be remade from other files, make skips the implicit rule search for phony targets (see Implicit Rules). Thanks to the good folks on #debian-mentors on OFTC for instruction and explanation in these matters.

debian: replace clean with override_dh_auto_clean The current version does not call the default dh_auto_build, which is a bug. This is required in particular for cleaning the build directories.

debian: replace build line with a override_dh_auto_build line This is more in line with how dh is supposed to work. In particular, dh_auto_build is functionally equivalent to the repeated "dh build --with python2 --buildsystem=python_distutils" used currently.

debian: remove clean target before implicit match rule This is redundant because it is a match-everything rule. Possibly a typo.

debian: Add DH_VERBOSE, commented out, for debugging convenience

evolve: wrap exchange.push() for compatability with core mercurial 4d52e6eb98ea

drophack: use `first` and `last` on smartset This matches the new changes in mercurial core.

evolve: use `first` and `last` on revset this match change in mercurial core. G: changed hgext/evolve.py

test: adapt to core mercurial 9ab18a912c44 This changesets improved the output of prompt during test.

evolve: adapt to core changeset 4f14303e8954 pushop.ret is now pushop.cgresult

merge with stable

evolve: update evolve merge message People are apparently unaware of --succ

import: fix the "is None" check for the Node We are checking the wrong variable.

test: remote "date" from the output of obsmarker meta Data is no longer a generic meta. it has its own field now.

test: adapt to mercurial changes Changeset 816be4ca4ae2 in core make hg config return non-zero when no value match the filter.

evolve: wrap setparents calls in begin/endparentchange Mercurial rev d259322a394b added a requirement to wrap any dirstate.setparents calls and their associated dirstate changes in begin/endparentchange.

merge with stable A couple of test fix were added on stable.

test: add glob annotations where Mercurial's run-tests.py suggests These happen to also be 5 of the 6 tests that warn about no result code when run on Windows. Probably not a coincidence. The tests previously warned about no result code whether or not it was run interactively. They only started working when test output changes were accepted in interactive mode, and these globs were added automatically.

evolve: really fix the 'grab' alias on Windows Something seems to have happened when importing cb36a4eb0157- it dropped the $@ argument to --rev, and it picked up a bunch of test changes for the obsolete sha1 replacement patch. Instead of backing it out and breaking the tests for the sha1 replacement, this just fixes the missing $@.

evolve: keep vague compatibility with 3.1 Matt Mackall work flow requires this to not crash in fire with 3.1. We apply basic bandage to stop the bleeding.

merge: all the stable sweetness into default

evolve: replace each obsolete sha1 in the description with its latest successor Obsolete csets are hidden by default and don't get pushed to the parent repo. In order to avoid broken references in commit messages, it makes sense to evolve those references to the latest and greatest successor, as each cset containing them is evolved. Of course, stale references can still occur if a commit in branch 'A' references something in branch 'B', and that something in 'B' is evolved but 'A' isn't subsequently evolved. This alleviates the user that is evolving a series of commits from having to 1) recognize that there is a hash that needs updating in any one of the series 2) look up the latest successor manually 3) hg amend -e The regular expression for matching and the logic for replacing are borrowed from the convert extension [1]. It might be nice for the output to state the reason that the reference couldn't be updated (it was pruned, split or diverged), but that may be excessive for something only displayed in verbose mode. (Maybe it should be a ui.status() instead?) [1] http://selenic.com/hg/rev/45562379ce4e

test: add parent hash to commit message in test-evolve.t This (slightly) reduces the changes to the test when hashes in the commit message are evolved in the next commit.

evolve: fix the 'grab' alias to work on Windows For some reason, the variable wasn't substituted on Windows in this case. From the test suite: $ hg grab 8 '' is not recognized as an internal or external command,\r (esc) operable program or batch file.\r (esc) This change seems hacky, but there isn't a readily available example of setting up a shell alias like this from a python module to know if there is a better way, and it seems like this is maybe just a convenience for tests, since there is no documentation for the aliases. The local copy of run-tests.py appears to predate the Windows support in the Mercurial repository's version, and fails each test with: The system cannot find the path specified. However, with this change and blacklisting test-simple4server.t, the tests can (mostly) be run on Windows like so: $ ../../hg/tests/run-tests.py --with-hg=../../hg/hg --blacklist windows Skipped test-simple4server.t: blacklisted Warned test-obsolete.t: no result code from test Warned test-tutorial.t: no result code from test Warned test-evolve.t: no result code from test Warned test-userguide.t: no result code from test Warned test-sharing.t: no result code from test Warned test-drop.t: no result code from test Failed test-prune.t: output changed # Ran 41 tests, 1 skipped, 6 warned, 1 failed.

debian: add README to the list of documents shipped with the package.

debian: add missing curl Build-Depends curl is required to run the tests.

prune: work around lazy revset slowdown Since 3.0 lazy revset is making some revset very slow. We currently work around the issue by using a simple loop instead.

readme: act that there will not be a 4.1.1 release

evolve: write a status message when the working directory changes Evolve changes the working directory during atop, etc which can confuse people as they are not aware that this happend. The ideal solution is to not have evolve change it, however mercurial limitations don't allow us to do that at the moment. So instead we are printing a status message that the working directory changed.

merge small default improvement before dropping compat with released Mercurial We are going to drop a bunch of compatibility layer.

pull: use discovery to pull less obsmarkers through bundle2 This hooks in the official API for bundle2

pull: run obsmarker discovery only on the common set If the discovery is run before the obsmarker push, pulled revs does not exist in the repository yet.

evolve: fix a typo in a long function name

bundle2: burn some more of the old code Some of it survived.

obsexch: respect todosteps when using the old push

compat: update the tests after the jump

compat: use in-core encodemarkers Now exist in core witha slightly different format.

compat: rename encodeonemarkers to _fm0encodemarkers This is getting renamed in core.

enable bundle2

drop the debug output

test-simple4server: add error output for http This is useful in case of failure.

compat: adapt to change to memctx Since core mercurial 650b5b6e75ed we must return None instead of raising IOError. Hooray for mads!!

evolve: use pushkeyescape from core It exists for all version we are compatible with.

evolve: display more message

evolve: drop a very old safe guard about bad marker The do not clean marker with nullrev successors. I assume none of them remains.

pull: drop the custom bundle2 part

obsexc: add support for evoext_pushobsmarkers_0 on localpeer This will unify the behavior of exchange in the tests.

evolve: allow read() from the magic StringIO

evolve: drop old obsmarker discovery code It as not caller anymore.

obsexc: use the common discovery We drop the hand made discovery and rely on the general one introduced some time ago.

obsexc: push nothing if push fail This is closer to the future behavior with bundle2.

discovery: hook on the official discovery for obsmarker This will let the discovery be done once and used by core.

discovery: use a different setup step for discovery This will ease the dropping of the other part later.

evolve: remove unused drop random

obshash: resist to unknown revision during discovery

code movement: gather discovery code together The discovery code is the one thing that will survive the great purge.

bundle2: drop custom compat We'll rely on the core implementation to use bundle2.

drop relevant marker compat

evolve: always use the transaction version of phase movement This drop compat with all known released version of Mercurial.

evolve: drop debugobsoleterelevant Core gained this capability usig `hg debugobsolete --rev REV`

evolve: yield to relevant markers handling in core The handling of obsolescence marker is now performed in core. If we detect a mercurial with such power we skip the wrapping from evolve. This changeset also suffer from massive diff from the change in display of obsolescence marker with parent information introduced at the same time in core.

test-wireproto: adapt to output change from core

test: update test to new date formatting in debuobsolete output The date is now a first class citizen with proper formatting.

test: update help output to future 3.2

merge with stable

pkg: make tests pass using the generated tarball Exclude tests/test-drop.t and include tests/_exc-util.sh, tests/dummyssh, and hgext/simple4server.py.

compat: always call metadata as a keyword argument Those function are gaining more arguments. using keyword argument keep use safe in all version.

test: work around a bug in debugobsolete The defautl date was wrong all along. So we use a fixed date for all tests.

merge with stable

uncommit: add a --rev argument The uncommit command now taks a --rev argument. This lets restore the file content in the current commit to another revision (instead of just is parent content). This still does not touch the working directory content.\ This allow the longly awaited: hg uncommit --hidden --rev 'precursors(.)'

readme: add missing changelog entry My dear friends changelog.

merge with stable

import: handle patch with no node information patch created by old Mercurial version or other tool have no node information. We cannot create marker in this case.

import: compare binary node with binary node when using --obsolete hex(N) != N

README: fix version number

relocate: fix typo

merge back with stable

Added tag 4.1.0 for changeset 4d5d101e878f

pkg: prepare release 4.1.0

merge default into stable Release 4.1.0 is coming

evolve: adds a --confirm option This option lets the use double check if it wants the evolve operation.

evolve: gather evolve output together We stop relying on ui.status being muted when --quiet is used. Instead we use plain write and hide this behind an explicite ui.quiet check. This will help use enforcing this output in the comming --confirm mode.

doc: forgotten amend

evolve: attempt to clarify the documentation around --all and --any This have been confusing to people. We try to be a bit more verbose in the evolve help.

evolve: re enable progress for all Progress is an important information for user facing slow push.

evolve: stop pretending we are pulling markers when we don't If discovery did not found any unknown marker, we should not display the "pulling marker" message.

evolve: do not even try to pull if all remote markers are known previously we were explicitly pulling an empty bundle.

evolve: add "obsolescence" in front of marked in the previous message

evolve: make the "X markers added" message during pull important

evolve: make the "pulling obsolescence marker" message important This is likely to take some time the user needs to know what is going on.

evolve: add "absolescence" in front of markers in the message

evolve: re-introduce the "pushing 42 markers…" message Informing the user about marker behind pushed sounds a good idea.

evolve: hide the OBSEXC message behind a config option This will lets most people ignore them while keep evolve dev having a close look at them. Some of the most useful messages will be reintroduced for all in coming changeset.

evolve: move OBSEXC progress in a dedicated function This will help use to rework them.

evolve: move OBSEXC message in a dedicated function This will help use to rework them.

Added tag 4.0.1 for changeset e914884fb721

evolve: prepare release 4.0.1

evolve: fix distribution for 4.0.0

evolve: update readme

evolve: update tested with statement

test: apply message changes introduced by mercurial 3.1

test: use `hg log` in the `getid` function using `hg id` to retrieve full lenght node requires to use --debug. This may include debug output (regarding branch cache invalidation for example) that breaks the test. We now use `hg log` with a custom template. This is a simple, clean and robust solution.

evolve: add a tr arguement to retractboundary Mercurial core is adding a transaction argument to its phase movement function. We do the same. If Mercurial appears to be an old version (without the extra args) we call it the old way.

relocate: add transaction around phase movement cheap way to acces access to the transaction object

uncommit tr

evolve: saner locking an transaction in `hg evolve` Each trouble solved used to handle locking and transaction on its own. We now have a top level locking and transaction. This will helps use making sure phase are moved within a transaction.

uncommit: saner locking scheme (and do it in the right order in the process)

prune: lock inside the try tss…

debugrecordpruneparents: release tr the same way than the lock Nicer code is nicer.

evolve: drop useless wlock in rewrite

divergence: actually use the hint that have been around for age Having a hint in the code is good, having it displayed is usually seens as better.

evolve: rename `tr` variable (for troubled) to `tro` tro is usually dedicated to transaction.

evolve: add a custom layer around retractboundary retract boundary is about to gain a new argument in core, we need somethign to handle this

merge with stable

evolve: point to the core mercurial tracker for bugfix As per Matt Mackall request evolution related bug should be filled again the main tracker as at some point al lof evolve wil be in core.

evolve: drop reference to 2.3 in the extension help text We are far away from 2.3 now.

readme: update the work in progress repository location

readme: update the official documentation location

evolve: deprecated --obsolete and --old-obsolete option on commit and graft Such option are unlikely to make it into core, so we deprecate them to avoid uer discovery them and getting used to them.

push: put phase in the same bundle2 than changegroup and obsmarkers Note that the usual phase push from core will be performed in all case. But the discovery should find already in sync phase at that time. The old ways sync will be properly skipped when this logic is introduced into core.

push: put obsmarkers in the same bundle2 than changeset When client is Mercurial 3.1 and server have proper evolve version and both side have bundle2 enabled, we'll includes a part containing obsolescence markers. When obsmarkers are included to the main bundle2 push, they will failed to be pushed if the changeset failed to be pushed (and reciprocally).

push: extract obsmarkers discovery in a dedicated function The need to factorise the computation of the markers to send in a dedicated function. This prepare the inclusion of obsmarkers in an atomic bundle2 push. For now, when obsmarkers are pushed using bundle2, they are still doing it on their own, in a dedicated bundle2 push.

evolve: update the tested with statement Tested with the soon to be release 3.1.

test: adapt to upstream message change A message gained parenthesis in 3.1 we reflect than in the test.

uncommit: improve error message for use with no arguments

test: use `hg log` in the `getid` function using `hg id` to retrieve full lenght node requires to use --debug. This may include debug output (regarding branch cache invalidation for example) that breaks the test. We now use `hg log` with a custom template. This is a simple, clean and robust solution.

readme: mention patchbomb usage and patch description guidelines on wiki

debian: add line to clean target to delete error files caused by failing tests

fold: improve error messages for multiple heads and roots This commit adds hints and i18n to the error messages about non-linear revisions, along with corresponding tests.

fold: reword error message for public commits This rewords the error message when attempting to fold public csets. It is somewhat clearer to not use contractions in formal writing. It also uses i18n for it. This commit also adds a new test for this error message.

fold: overhaul handling of revisions with --rev (BC) The fold command parsed the revision arguments in a very peculiar and idiosyncratic fashion: if revisions were passed without a --rev argument, then they would all be extended to ".", but if they were passed with --rev, then no extension would happen. Passing revisions both with and without --rev would abort. This is inconsistent with the way all other hg commands parse revision arguments. We have several examples of command where several revisions are passed, and the --rev option is optional for specifying those revisions (update, strip, export). This patch alters the way in which fold parses its revision arguments. No distinction is made between revisions passed with or without the --rev argument. Regardless if a single or multiple revision is specified, all will be folded together into the parent of the working directory. If the --exact argument is passed, then the parent of the working directory is ignored and the specified revisions must be a single contiguous line. The docstring and tests are modified accordingly.

fold: emit error message when folding a single revision Previously, a confusing error state would happen if the revision set to fold was a singleton.

fold: clarify message for empty revision set and abort instead (BC) I find it clearer that there are no revisions to fold because none were specified. Otherwise it seems ambiguous: maybe there are no revisions to fold because it's impossible to fold whatever was given? In analogy of other commands that are given no revisions (e.g. strip, graft), this is also now an abort instead of a mere error message, which is a BC.

evolve: do not use _ as an unused variable The _ variable is the i18n function from core Mercurial, so locally assigning to it can lead to name clashes.

merge with very old 2.2 branch

test-obsolete: make log templates more consistent: add {desc} to one This has the extra added benefit of making the divergence situation easier to understand.

test-obsolete: explicitly show which changesets are divergent

merge with stable

update readme (I should have a hook preventing me to push to public repo with uncommited changes)

evolve: add --tool option so we don't have to use HGMERGE

amend: add -U/--current-user option (inspired by mq)

tests: fix grammar, spelling, punctuation in comments

evolve: minor reorganisation of code responsible for evolve output This does not change any of the semantic as status is not printed when --quiet is provided. This juste make it more explicit that the output are related.

template: add a troubles keyword This keyword list all evolution troubles that affect a changeset. Evolution troubles can be "unstable", "divergent" and "bumped".

docs: update copyright statement used by sphinx

docs: add concepts guide (the set theory behind obsolescence)

docs: add guide to sharing mutable history

docs: add new user guide This has also been reviewed to death on evolve-testers. There are still a couple of short sections to write (clearly marked "TODO"), and one example to add. But (if I may be so bold) this is a gigantic improvement over the current docs, so it really should get merged. Incidentally, the figures are all SVG files created with Inkscape. They're not perfect, but they're pretty nice. Anyone who knows a better way to create technical diagrams is welcome to contribute. One wart: there's a test script that accompanies the document and largely duplicates it, but I haven't unified them. I've been concentrating on writing the best possible content, not on fiddling with tools. I suspect that unifying them will be non-trivial, but definitely worth doing.

docs: rewrite index page (including dangling links to future docs) This has been reviewed to death on the evolve-testers mailing list. I've made some minor tweaks since the last round of reviews, but the main content is the same.

amend: add -D/--current-date option, just like mq's qrefresh has Carefully designed so we can easily add -D to other changeset-creating commands (probably anything that takes -d), and so that we can add -U/--current-user as well. When that's done, the date and user options should be very similar to those in MQ.

amend: explicitly test -d option

amend: in tests, do not rely on defaults -- always use explicit -d Having a default -d option will make it hard to test -D/--current-date, which is coming shortly: presence of -d overrides -D, just like with mq's qrefresh.

evolve: fix createmarkers() wrapper to accept an iterable Docstring in mercurial.obsolete says "<relations> must be an iterable of ...", and hgsubversion takes it at its word and passes a generator. Until around Mercurial 3.0, this did not cause any problems, but now it does: in a repo with both evolve and hgsubversion enabled, pushing to Subversion when obsolete changesets are present causes a crash: [...] File "/home/gward/src/hgsubversion/hgsubversion/wrappers.py", line 346, in push obsolete.createmarkers(repo, relations) File "/home/gward/src/hg-stable/mercurial/extensions.py", line 196, in wrap return wrapper(origfn, *args, **kwargs) File "/home/gward/src/hg-evolve/hgext/evolve.py", line 332, in _createmarkers relations[idx] = (prec, sucs, meta) TypeError: 'generator' object does not support item assignment Since hgsubersion is playing by the documented rules, evolve must be the guilty party here.

simple4server: backport the bundle2 exchange

evolve: install progress support for the bundle2 pull path The custom wireprotocol command had a trick to display progress while pulling. We reinstall such logic for the new path using bundle2. Its notable that we are using the bundle2 advisory parameter for this purpose.

evolve: install progress support for the bundle2 push path The custom wireprotocol command had a trick to display progress while pushing. We reinstall such logic for the new path using bundle2.

evolve: add a pull path using bundle2 Instead of using a dedicated wireprotocol commands, we use bundle2 to transmit an obs marker parts. This aims at both testing bundle2 more and to limit the amount of special code we needs to put in simple for server to fit our needs. The massive test changes comes from the fact we can use this fast path for both remote and local push.

evolve: advertise obsmarker creation in the transation hook This will let extensions hooks on marker exchange.

evolve: add bytes and new marker data when processing part This will helps use to keep printing useful message when pulling through bundle2.

evolve: add a push pass using bundle2 Instead of using a dedicated wireprotocol commands, we use bundle2 to transmit an obs marker parts. This aims at both testing bundle2 more and to limit the amount of special code we needs to put in simple for server to fit our needs. The massive test changes comes from the fact we can use this fast path for both remote and local push.

evolve: make exchange output compact in the old pushkey case too.

evolve: compatibility with memfilectx change The future 3.1 have have more sophisticated memfilectx object. We add a compatibility layer for them.

evolve: abstract access to context.memfilectx This class is getting altered in the future Mercurial 3.1.0. This changeset prepare a compatibility layer.

import: drop version check for ``import --obsolete`` This code base does not support anything below mercurial-3.0 anyway.

evolve: bump requirement to 3.0.1 Use of bundle2 for pulling will require this version or above.

test: fix test-import condition The help text is ``"only(`` not `` only(``

merge with stable

evolve: make most line lenghts 80 characters or less There are still a few lines that are above 80 characters in length. Those have not been changed because doing so would make the code a bit less clear.

evolve: start all util.Abort messages with lower case

evolve: improve wording of a few of messages

evolve: fix a couple of typos

evolve: fix spelling error

evolve: more compact output in the wire protocol case We made the wording more similar and use less line. The writing operation is usually fast so we do not needs a specific line for it.

evolve: test exchange through wireprotocol The wireprotocol version of the exchange was only tested in the `simple4server.py` case.

evolve: align working during obsmarker push using pushkey lets use the same wording everywhere to prevent user confusion.

evolve: drop some pre-3.0 compatibility code This extension already requires Mercurial 3.0

evolve: update the errors message to request mercurial 3.0 and above And update the checking code too. This extension already requires 3.0 for some time.

readme: remove some duplicated entries Those changes where backported to 3.3.2.

readme: remove embarrassment There were… conflict marker in this file. Its over, they are gone now.

merge with 3.3.2

Added tag 3.3.2 for changeset a03ea39aca2a

prepare release 3.3.2

fold: add squash as a possible alias In order to respect the habituation of the majority of DVCS users and to make this feature more easily discoverable, the very common "squash" terminology should be added as a synonym to "fold". Since git does not have a squash command, this should be safe.

fold: add --message and --logfile options Like other commit-creating commands, this add two options for specifying the resulting commit message, with tests. If either of these options is specified, no editor is popped up asking for a commit message.

prune: update to successor rather than parent when prune '.'

import: --obsolete flag for automatic obsolescence marker creation A new `--obsolete` flag is added to import. When present, the new node will be marked as a successors of the one specified in the `Node` field of the imported patch. No marker are created when revision have the node expected in the patch. This improves email based work flow where implicit rebase are likely to happen and extra information are lost, changing the hash. This new behavior requires a flags, otherwise the `hg export x | hg import -` idiom would change, turning the source obsolete. (Changing from `hg graft x` to `hg rebase --dest . --rev x`) This change only takes effect when using Mercurial 3.0 and above

merge with all other change to 3.3

update 3.3.0 readme to include minimal mercurial requirement This clarify the situation.

evolve: fix grammar in a comment

README: document how to run the tests

uncommit: change 'kill' to 'prune' in error message 'kill' was renamed to 'prune' Long time ago.

readme: the forgotten update strike again

evolve: protect call to rebase within a wlock (#42, #35, #16) Without a wlock, repo.commit would blow away the dirstate's parents on OSes that have no 'os.symlink' support in python, leading evolve to produce a merge instead of a rebase. If a user ran the rebase command instead of evolve, then things would work because rebase is wrapped in a giant wlock. Unfortunately, we can't use the same idea of wrapping the evolve command in one giant wlock because that's too early in the process. If the lock did wrap the entire evolve command, then the working directory would save its current parents which, since rebase hasn't been called yet, would be just p1. Therefore, we need to obtain the lock *after* the dirstate's parents are changed but *before* the call to rebase. This way ensures that when a conflict happens the working directory correctly shows both parent changeset.

readme: update the readme with all missing entry One days one will stop forgetting to update it.

readme: rephrase the changelog entry regarding the new exchange Lets try to have it readable by human being.

readme: drop the reference to fastobs Its dead Jim.
