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.

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: update cmddebugrecordpruneparents to the new markers creation API The parents information are now first class citizen. (caught by laurent using pylint)

evolve: drop useless return This return statement is never reached. This a actually a good new because its variable was undefined. We remove it. (caught by laurent using pylint)

evolve: add missing import (caught by pylint)

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.

evolve: remove unused variables As suggested by pyflakes, remove 5 unused variables in the evolve module.

evolve: remove unused code in _evolveany remove some code that was doing nothing useful in _evolveany.

evove: remove unused imports Three imports where unused in the evolve module.

tests: ensure we keep capturing output In 3.4, output capture with bundle2 is disabled by default on local push.

inhibit: updating to a obsolete commit prints warning message We move the inhibition marker in the same wlock than the update operation, this clears the warning message. To make it work we display the warning message on lock release in evolve.

evolve: stop conditional wrapping of _checkinvalidmarkers We support down to Mercurial 3.3, all such version have this function.

evolve: stop conditional wrapping of _getbundleobsmarkerpart We support down to Mercurial 3.3, all such version have this function.

evolve: stop conditional wrapping of _pushdiscoveryobsmarkers We support down to Mercurial 3.3, all such version have this function.

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.

Add "documentation update" to the changelog.

docs: cover 'touch' command

docs: explain --hidden option Also move the discussion of revision numbers up, and splice the explanation of --hidden into it.

docs: tweak wording, punctuation for better readability

docs: flesh out unfinished bits in the intro page

docs: revive the explanation of divergent changesets in the sharing guide

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

Added tag 5.1.2 for changeset e886bc501796

evolve: have a stable manifest content when solving bumped We cannot really use iteritems here.

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.

evolve: fix manifest usage to match upstream The manifest class upstream is no longer a dictionary, so switch to using an API it does support.

drophack: fix to match upstream repair.strip repair.strip upstream now assumes the input nodelist is a list, so update to match it. The upstream change only affects the name of the backup bundle, so this shouldn't affect any other functionality.

evolve: prevent a crash in httpclient_pushobsmarkers() when pushing I've been running into a crash when pushing from my hg repo in a Fedora 16 VM to Win7 running 'hg serve', even with extensions disabled on both sides: ../hg push -r . pc pushing to http://192.168.1.4:8000/ searching for changes no changes found pushing 2 obsolescence markers (263 bytes) ** unknown exception encountered, please report by visiting ...

The failure occurs even when there _are_ csets to push. There was no crash if no obsolete markers needed to be pushed. At any rate, this code was stolen from httppeer._callpush(), where it calls self._call(). The socket exception handling wasn't necessary to fix the crash, but the calling code might as well be duplicated in its entirety. A successful push with this patch looks like this.

evolve: use 3.2+ fullreposet to evaluate argument set (issue4515) getset() has no compatibility wrapper for old-style argument and we don't want to add more hacks in Mercurial core.

evolve: cache marker encoding to avoid performance degradation The main overhead in bug 4518 is caused by calculating relevant markers and encoding markers into the correct format. Calculating relevant markers takes (worst case) ~ 0.12 seconds. Encoding markers takes (worst case) ~ 0.06 seconds. Caching encoded markers takes care of the second part and speeds up cloning in bug 4518 by about 35%.

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.
