readme: clarify the branch policy

Added tag 6.3.0 for changeset 6da4ca7b3e4f

packaging: prepare release 6.3.0

test-compat: merge with mercurial-3.9

test-compat: merge with mercurial-4.0 branch The new 'olog' command is not working with 3.9 so we skill all mentions of it in the tests. This also apply to the topic extensions.

test-compat: merge with mercurial-4.1 hg log has no trouble field in mercurial 4.0, output fixed.

test-compat: merge with stable Nothing special to report, minor test-metaedit.t output change.

merge with default

compat: fix stablerange for mercurial 3.9 Lrudict.get change of api between mercurial 3.9 and mercurial 4.2. Bypass this limitation by using lrudict.__getitem__ and catch the KeyError directly.

template: fix successors and precursors templates In mercurial 4.1-, the gen argument is expected to be an iterator and not an iterable, fix successors and precursors templates.

lint: remove double newline in test file Test file test-stablesort-criss-cross.t contained two double newline, I remove them.

template: fix precursors template for older mercurial version In mercurial 4.1 and below templatekw._hybrid require the gen argument to be different than None. Manually compute the same default output for these older mercurial versions.

compatibility: backport mercurial 176d1a0ce385 Backport obsstore.relevantmarkers change for including previously forgotten pruned obs markers. Target mercurial version lesser than 4.3. This impact multiple tests. All test changes has been manually checked. Since the computation of relevant obsmarkers have changed, we are bumping the cache schema version. So that caches get recomputed.

evolve: fix import order

compat: adapt to buildobsmarkerspart move The function has been moved in e70d6dbde713 so we must we search in both location.

effetflag: detect other meta (extra) changes Check other changeset meta other than branch and *_source and if there is a change, set the METACHANGED effect flag. Add a test for this scenario with a topic change.

obsdiscovery: add an option to disable all obsdiscovery On large repository, computing the obshashtree can we as slow as resending everything. We give the option for people to opt out.

effectflag: better diff detection Improve the diff detection algorithm to have less false positive like in the case of a rebase that move the hunk in the file but the hunk stays the same.

effectflag: add a test for content detection Add a test for diff detection when the diff is different but only because of line numbers. The test is a append at the end of the file and we try to rebase it. We shouldn't detect a content change, it will be done in the next patch.

test: fix test-evolve-effectflags dates Mercurial < 4.3 don't have default date so add globs in the test-metaedit.t file.

test: fix metaedit tests by forcing dates Mercurial < 4.3 don't have default date so restore aliases forcing date in the test-metaedit.t file.

test: split test-stablesort.t in two This is the longest running test so we split it in two to help with parallel execution.

obsdiscovery: automatically pick protocol in a list This makes the code cleaner, clearer and more flexible. This also prepare the ability to disable obsmarkers discover entirely.

obsdiscovery: extract push-obshashtree discovery in a function This will help use to simplify the code.

obsdiscovery: directly use the 'only' revset for obshashtree The revset now exists and is fast. This remove the needs to hold a reference to "revs" in that code.

obsdiscovery: extract push-obshashrange discovery in a function This will help us to simplify the code. The code is updated to directly use 'outgoing' missing so that is no longer needs to access 'futureheads'.

obsdiscovery: merge two distinct if statement It did not made any sense for them to be split.

obsdiscovery: extract '_canobshashtree' having this as a simple function will help use to generalise the obsdiscovery algorithm we use.

obsdiscovery: move code inserting discovery at the end of the file This makes it easier to reuser function defined earlier in the file.

obsdiscovery: trust core to do the right thing if no discovery is available This is fixed for a long time now.

obsdiscovery: factor the "do we push markers" check out This clarify the code a bit.

stablerange: also respect the 'warm-cache' config This will help large install to enable obshashrange as "opt-in" without impacting other repositories.

debugstablerange: cleanly "Abort" when no revision are specified Previously we had a traceback from a max on an empty sequence.

stablerange: use last recently used caching for revisions associated to ranges This does not make things faster but at least it make them able to finish on large repositories.

stablerange: report progress more often in slow case For small repositories the time spent in progress was problematic. However on large repository it quickly becomes negligible, so we add a way to detect this case and report more often in this case.

template: update successors template output Use templatekw._hybrid as return value for precursor template, it's nicer and easier to play with than returning a formatted string.

test: extract metaedit tests into test-metaedit.t test file The metaedit command deserver it own test file and this shave of 15% of the runtime of test-evolve.t one of our longest tests.

template: update precursors template output Use templatekw._hybrid as return value for precursor template, it's nicer and easier to play with than returning a formatted string.

template: skip "fate" in test output when empty This should clarify the test output a bit.

template: skip "successors" in test output when empty This should clarify the test output a bit.

template: make the template definition more manageable Readable config is readable

template: skip "Precursors" in test output when empty This should clarify the test output a bit.

template: move each template on its own line during tests This will clarify the various coming changes around template.

refactoring: rename obsfate template to obsfate_quiet As I don't know how to handle templates arguments, create different templates for each verbosity level wanted.

doc: add documentation about effectflag experiment

effectflag: split effect flag meta Split effect flag meta into 3 separate flags: - USERCHANGED - DATECHANGED - BRANCHCHANGED Also display them separately for the moment, they could be grouped back together if we want later.

tests: update missing amend (I need a hook)

template: update obsfate to be more human friendly Approach the obslog output for the moment.

template: add the obsfate template Reuse _getobsoletefate and nextvisiblesuccessors to easily get the obsolescence fate of any node. The limitation is that obsfate is as precise as these two functions, which is not great for nextvisiblesuccessors.

refactor: extract obs fate algorithm from _getobsoletereason Refactor _getobsoletereason to extract the obs fate computation into a separate function, it will be used later and put it in obshistory as it will be needed in other files. Rename _getobsoletereason to _getobsoletefateandsuccessors.

template: add successors template The successors templates display the closest visible successors of each changeset, we may have gap, like in this case: A -> B -> C -> D If we display A, C and D but not B, we can't display than B is the closest successor of A because it's not displayed. We display C as the closest successor of A instead.

template: add precursors template The precursors templates display the closest visible precursors of each changeset, we may have gap, like in this case: A -> B -> C If we display A and C but not B, we can't display than B is the closest precursor of C because it's not displayed. We display A as the closest precursor of C instead. Add a new test file as we will need to generate theses gaps and modifying test-evolve-obshistory.t will lead to many unrelated lines changes.

refactor: extract templates into a new file Extract evolve template from evolve/__init__.py to evolve/templatekw.py as more templates will come in the future.

obshistory: add the all option to obslog to show the while obs tree Add a --all option to obslog in order to display also the successors of each obs markers. It has the effect of showing a more comprehensive graph when a split or a divergence happened.

merge with stable

readme: update changelog for 6.2.2

test: fix test-evolve.t Metaedit take the current date when no date is given. When we added default- date, the date ended up to be the same and the behavior changed. Fix the text by disabling default-date in the metaedit call and update the comment about what is needed to fix correctly the test; take the changeset date when metaediting only one changeset.

test: split evolve cycle tests in a separate test file

evolve: fix --rev with --list This was untested and never worked.

test: improve the globing for obsmarker date If we force the date of obsmarkers, they will no longer include "20".

test: rename all olog references Replace them by hg obslog which is more explicit.

test: improve the globing for obsmarker date If we force the date of obsmarkers, they will no longer include "20".

documentation: recomment using blackbox with the obshashrange experiment

merge with stable

packaging: update the development version number This helps catch non-tagged version installed with pip.

Added tag 6.2.1 for changeset 0af99106b075

packaging: prepare release 6.2.1

compat: merge with stable Stable has multiple changeset that solve deprecation warning for the future Mercurial 4.3.

test-compat: merge with mercurial-3.9

test-compat: merge with mercurial-4.0 branch

test-compat: merge with mercurial-4.1 Nothing to report

test-compat: merge with stable Nothing special to report, minor blackbox output update and color extensions was needed for test-prune.t

deprecation: fix dirstate.beginparentchange deprecation warning Replace calls to dirstart.beginparentchange and dirstate.endparentchange to dirstate.parentchange context manager.

deprecation: fix cmdutil.command deprecation warning

obshistory: be more flexible about createmarkers API The API got touched in core.

inhibit: be more flexible on createmarkers API This API got touched in core.

merge with stable

obshashrange: document the experiment This should help people jump in.

obshashrange: add an option to disable local cache warming The cache still a bit too volatile an costly to update. This offer a way for developer working copy to only compute it when used.

obshashrange: re-warm less revision after reset rewarming every single revision get very expensive quickly. Instead we warm few key revision and rely on the fact this will warm enough useful subrange.

effectflag: simplify meta data change testing Let us just do one larger test. G: changed hgext3rd/evolve/obshistory.py

effectflag: add a small comment to suggest improvement The code run but we will likely need something easier to extend.

effectflag: handle invalid data If we get a marker with an invalid input we should not crash the whole process.

effetflag: move the flag back with the test of the creation logic Previous changeset was published by mistake.

obshistory: display informations from the obs marker effect flag Leverage the effect flag to actually show what change for each obsmarker in the obslog command. (first basic version).

test: add (glob) to globed line Ingloriously forgot to amend.

effectflag: add test combining multiple flag We check that multiple changes might be detected a the same time.

effectflag: basic diff change detection We adds some basic diff detection.

effectflag: detect parent change Add the detection of parent changes.

effectflag: detect meta changes Add the detection of known meta field changes. The known meta fields that we check are: - user - date - branch

effect-flag: rework existing test to prepare for mor tests

effectflag: allow to save effect of change in obsmarkers Obsmarkers lack a precious information, what are the changes between the source and the destination. This could be several thing: - The description has changed, with a amend -e for example - The parent has changed, with a rebase for example - The content has changed, with a amend for example - The meta, like the user, has change, with a amend -u for example Or any combination of them. We hijack the createobsmarkers in order to compute the modification and store the effect flag which is basically a bitfield of the changes list above and we store it in the metadata for the moment. The advantage of computing the flag just before creating the obs marker is that all commands will immediately be compatible and we can start working on the UI display of the flag. As a future optimization, the commands will be able to pass the flag directly or data to help computing them, for example amend knows if the description has changed or rebase now if the parent has changed, virtually removing the overhead. To start simple, this patch add the detection and storage of the effect flag when the description has changed. And hide it behind an experimental flag disabled by default 'experimental.evolution.effect-flags'. More flag will follow.

readme: fix version number

next: prevent a color related crash when evolve This was not caught by test because they run color less.

prune: prevent a color related crash when the working copy is moved This was not caught by test because they run color less.

evolve: adding longer aliases for olog Novice users will likely find the longer versions more obvious to understand what they're doing (olog only makes sense once you already know what it does). Especially on the help page, "obslog" will be easier to find and make sense of.

debugobsstorestat: add markers size information We adds some extra information about markers size in all known format.

packaging: bump version to 6.3.0.dev

merge back with stable (post-release)

packaging: bump version to 6.2.1.dev

Added tag 6.2.0 for changeset d4ee0274a8ef

merge back with stable

merge with future 6.2.0 No extra change were needed compared to 3.9.

merge with future 6.2.0 The new 'olog' command is not working with 3.9 so we skill all mentions of it in the tests. This also apply to the topic extensions.

merge with future 6.2.0 Minor unrelated output adjustements were needed.

merge with future 6.2.0 There are been (multiple) minor output changes.

packaging: prepare release 6.2

debian: fix email

topic: update 'tested with' and readme We are compatible with Mercurial 4.0 and above

readme: rearrange readme before release There won't be a bugfix release (and other cleanup)

test: reduce output size to fight unstability Until `hg touch` can be more stable, we have to do this :-/

tests: disable blackbox for 'getid' This will significantly simplify the blackbox log.

compat: handle lack of 'util.timer' for pre 4.2 version We keep compatibility with previous Mercurial version by redefining the timer when needed.

test: enforce color to be enabled 4.2 enable color by default and start to get used in test. So we add this to the test for previous version.

merge with default

tests: add a test about strip with obshashrange enable I've seen some traceback but I cannot reproduce them. This tests seems useful anyway.

obshistory: add a json test with cycles

tests: glob an absolute path The ssh command path was in full and pointing the mercurial checkout of the last one who touched the test.

olog: document the default value We actually display the log for '.' which is useful.

readme: rearrange changelog content blackbox is more important than the various caches changes.

obshistory: rename the command to "olog" The command start to look good enough to be handed out to user. We replace the old and useless "olog" alias in favor of the new command.

obshistory: move the command into the obshistory module The root module is far too large already.

obshistory: add docstring to cmddebugobshistory Add debugobshistory command documentation based on the log command documentation.

obshashrangecache: make sure we re-warm the cache after a reset This will "mitigate" the effect of dropping existing entries when new markers affect existing range.

obshashrangecache: precisely track affected revs when adding new markers This will be useful when we start doing finer grained invalidation (instead of dropping all data).

debugobshistory: handle multiple cycles We previously handled up to one cycle only. This is now fixed.

test: clean the debugobshistory cycle test Use 'desc(...)' instead of revision numbers. Also blank lines between commands in the same test

obsdiscovery: add more debug output we add a summary debug output to help gathering data.

discovery: log information about obshashrange We augment the blackbox output to help with data gathering.

obshistory: add a graph option on the debugobshistory command Add a graph option (--graph) to the debugobshistory. The output is like the 'hg log -G' output. The option is activated by default but can be deactivated with '--no-graph' option. There are various issue with the current implementation (multiple cycles handling, N² complexity) but this can be fixed later.

obshistory: import 'node' as 'nodemod' This simplify the next changeset.

label: add a label for the node in the "wc now at" message MOAR COLOR FOR THE COLOR GOAD!

label: rename 'evolve.short_node' to 'evolve.node' A wider labelk will helps compatibility.

obshistory: refactor debugobshistory Rename the function and extract the heavy work of the command in a separate module named obshistory.py

test: adapt to change in cache warming in core Core Mercurial has a more rational cache warming strategy now. 24f55686a63d stopped warming of the cache after every changegroup application (in favor of end of transaction warming). This reflect in the blackbox test output.

test: adapt to change in cache warming in core Core Mercurial has a more rational cache warming strategy now. 2b6692df1bdf stopped warming of the cache after every commit (in favor of end of transaction warming). This reflect in the blackbox test output.

stablerangecache: avoid crash when 'cache/' directory is missing If the directory is missing, we create it.

obshashrange: avoid crash when 'cache/' directory is missing If the directory is missing, we create it.

tests: apply output changes from core fix Mercurial core fixed a bug were the obsolete set (and all depending data) stayed invalid after markers were merged. Fixing this bug is fixing some bad output on the evolve side so we apply the output change.

packaging: mention 'dev' status in the version number

color: update the shorttemplate to use colors

merge with stable

obshashrange: cleanup 'valid' life cycle - reset is only called when we detect a strip, the on disk data are invalid, - after a reset, we should not keep using the data base connection, - after a write, the on disk data are valid.

obsrangecache: raise programming error when using an unwarmed cache This will provide a better experience for developer using this the cache.

obshashrange: stop marking on-disk data as invalid on clear This was abusing and prevent proper use of the on disk cache.

obshashcache: purge the meta line before writing a new one Otherwise we get multiple lines and this gets messy.

obshashrange: drop spurious whitespace

obshashcache: invalidate affected cache entries on side Calling reset during upgrade is screwing up the cache key update.

obshashcache: properly break out of all loops

dualsourcecache: simplify cachekey.clear We do not needs the super call anymore and we can make the reset case more explicit. So we do.

tests: small test update This is a bit clearer.

dualsourcecache: fix obskey return by _checkkey The function was returning the old key instead of the new one. This is now fixed.

test: update test-obsolete.t to use common.sh The definition of getid() in the test file was wrong, use the one from common.sh instead

obshashrange: log reset from new markers This will help tracking performance impact from current limitation.

dualsourcecache: log cache reset

stablerange: log time spent updating the stable range

cache: track time spend updating various cache This produce more useful blackbox log.

obshashrange: adds blackbox usage in tests This will help track the validation of the cache.

obshashrange: test behavior in case of rollback The cache should be properly invalidated.

obshashrange: extend tests We test more situations.

dualsourcecache: add a cache name This will be used to automatically log message for blackbox

obscache: stop definition of the empty key

obshashrange: keep value fetched from sql in memory This will reduce the number of roundtrip to the data base we need.

obshashrange: stop inheriting from 'dict' A simple dictionary attribute seems more simpler.

merge with stable

obshashrange: to not overwrite the list with the set We reusing the list variable lower in the code.

obshashrange: properly break out of the two loops Otherwise we would continue to iterate even after we reseted the cache.

obshashrange: fix reset conditional If the revision is in "revs" we should not reset the cache. The old code was wrong (Thanks goes to new tests for catching this).

cache: ensure we warm stablerange cache before the obshashrange cache I've been seeing traceback that seems to be happening because of issues in this area.

evolve: fixing obscache invalidation This was missing a call to the parent's destroyed(), such that any transaction after stripping some nodes would result in a crash (by attempting to read nodes which were stripped).

obshashrange: warm the cache at the end of each transaction This will help having warmed cache for read only client. The warming is still imperfect in case of markers that trigger a reset, but we are in a better place than what we used to be.

obshashrange: warm cache outside of loops The performance impact will be lower

obshashrange: "update" the cache on each transaction close Right now the "update" does not really file the cache, but it will detect invalid situation and clean them.

obshashrange: properly invalidate the cache on destroyed Copy paste is the scurge of code source.

obshashrange: properly drop the current connection on clear

obshashrange: exit early if nothing to write

obshashrange: use the dualsourcecache as a base for the cache This will easily open the way to incrementally updated obshashrange cache. Small update are needed to the data base schema so be bump the version Currently the update function is not warming the cache (but details case where it is invalidated).

obscache: makes dualsourcecache compatible with obshashrange cache needs The goal of the abstract method is to be reusable. So we make sure it is reusable.

readme: add a changelog entry about the more efficient obscache

obscache: extract a data agnostic class We now have an independent class that we can reuse for other purpose (eg: obshashrange cache)

obscache: extract the actual data update in a dedicated function This will help extract a data agnostic class.

obscache: move an assert to a lower level

obscache: use 'nullid' as the hash of an empty obsstore This align this result with what we use for 'emptykey'

obcache: move empty on the class We'll extract a smaller data agnostic class but we need to gather all method on it first.

obcache: move _checkkey on the class We'll extract a smaller data agnostic class but we need to gather all method on it first.

obcache: move updateneeded on the class We'll extract a smaller data agnostic class but we need to gather all method on it first.

obshistory: only display each revision once in debugobshistory When using a revision range, the same precursor could have been displayed more than once. Use a cache to display each revision only once. It's a fix until we found the nicest way to display obs history.

obshistory: display a message when one marker node has no change ctx When exchanging obs markers, there is some change contexts referencing change contexts that are not available locally. As we cannot display informations about them, instead print a message saying so.

ui: hg topic now display if current revision is in bad state (issue5533) Previously, hg topic didn't showed the state of the current revision. Now if show both informations.

obsstore: also guard agains changing object in '_checkkey' The 'upgradeneeded' function needs to be able to pass the object it fetched once.

obscache: guard from changing changelog or obsstore object We access these object once to make sure they will never change through the function (and their content will be fixed).

obscache: return the new data along-side the upgrade needs (and cache key) Having one function returning consistent data will help prevent race.

obscache: use the smaller scope function This make the function simpler and allow larger update on the 'upgradeneeded' one.

obscache: extract the cache key validation in its own function This help keep the "up to date logic" simpler and prepare a more complex version of the "upgradeneeded" logic that would return the full data needed for the upgrade.

obshistory: use formatter instead of ui.write in the debugobshistory command Replace ui.write with a formater to have template support and json output. Update tests to assert json outputs.

ui: Fix hg stack json output Previously 'hg stack -Tjson' generated invalid output like: [ { "isentry": true, "topic.stack.desc": "...", "topic.stack.index": 1, "topic.stack.state": "current", "topic.stack.state.symbol": "@" } ] , { "isentry": true, "topic.stack.desc": "...", "topic.stack.index": 1, "topic.stack.state": "current", "topic.stack.state.symbol": "@" }, { "isentry": false, "topic.stack.desc": "...", "topic.stack.state": "base", "topic.stack.state.symbol": "^" } ] I de-indented the fmt.end() to generate this output: [ { "isentry": true, "topic.stack.desc": "...", "topic.stack.index": 1, "topic.stack.state": "current", "topic.stack.state.symbol": "@" }, { "isentry": false, "topic.stack.desc": "...", "topic.stack.state": "base", "topic.stack.state.symbol": "^" } ] I've also added a test case.

topic: configure some default color for topic This makes thg usable

topic: automatically configure thg to display topic If no other config is set, we configure Tortoise-hg to display topic. This should helps usability.

readme: update readme to mention 'debugobshistory'

obshistory: add some color

obshistory: add a debugobshistory command to show obs history of a revs Add the debugobshistory command that accept a revision range and display the obsolescence containing each revision in the range. For the moment, it only displays the predecessors.

tests: add the commit style checker from Mercurial

obscache: update the cache key in place Instead of computing the key in place, we update the existing one using the data used for the incremental update of the content. This will help reaching purely incremental cache eventually. The 'getcachekey' function is dropped as it is no longer used.

obscache: distinct 'clear' and 'reset' We make a difference between basic invalidatiton (or lack of loading) and 'reset' (current cache data are invalid). We can now ensure a non-None key when we start the update. This will allow us to "update" the existing key instead of recomputing one from scratch. This is more efficient and less racy.

merge with stable

serveronly: also enable the obscache for server only setting The obscache is useful and speeds things up. So we also enable for server only setting.

obscache: document a possible way forward to skipping obsstore parsing We document a possibly viable idea for updating the cache on new revs without having to fully parse the obsstore.

obscache: update some documentation Update some data and do some proof reading.

obscache: Only access the new obsmarkers for marker update Since we know what what is the part of the file with "new" markers we can just access these. If the cache was up to date before the transaction, we'll re-parse data we just wrote. See the inline comment for details. This is good enough for now.

obscache: extract _updatemarkers code into its own function This split the update logic from the bit retrieving markers. That cannot be bad.

obscache: extract code to update from new revision Code cleanup and prepare upstreaming. The make the code more likely to work with the key validation returning an iterator of revs to update the cache with.

obscache: move assert earlier in the code If we are to crash, let us crash earlier.

opening mercurial 4.1 compat branch This branch will receive test update implied by the 4.2 → 4.1 changes.

obscache: skip writing to disk if the data did not changed This will avoid rewriting the cache for every single transaction.

obscache: skip writing if the cache is empty if the cache is empty, we can just skip writing to disk.

obscache: set a valid "empty" cache key if the cache is missing This avoid detecting bad cache when it just happens to be no cache.
