branching: create the mercurial-4.3 test compatibility branch This branch will contains the expected test output with 4.3.

branch: merge with stable to prepare 6.7 release In addition, Mercurial 4.4-rc is out, so we need to update the expected output.

changeloge: add details about topic-mode

effect-flag: remove wrapping of createmarkers for Mercurial 4.4 Now that effect-flag has landed in Mercurial 4.4, we don't need to wrap createmarkers for this version anymore.

stack: order the adjective of changeset The new order give more interesting result: * base current * base unstable * current unstable It seems more harmonious this way. Base seems the most core and immutable adjective describing the element. Then current is a volatile but important one. Finally, unstable is less information than current, so it goes last.

stack: show current and unstable also for t0 and bases

obsfate: use core version of obsfate if available Let us use the upstream version whenever available. The operation display is currently disabled to ease with the test changes.

topic: register config items There is a couple more hoops to jump through but all config items used are now registered.

directaccess: register config item if possible Mercurial 4.4 warns about unregistered config.

evolve: registed configitems if available The config are registered as 'dynamicdefault' because we still need to explicitly pass the config option for older version of Mercurial. (4.2 and before).

inhibit: compatibility with 4.4-rc

branching: merge with stable Merge with the inhibit fix.

inhibit: respect '--keep' when handling rebase clean up

test: adapt to change from 537de0b14030 If we use phase for pull/push this impact some debug output. CORE-TEST-OUTPUT-UPDATE: 537de0b14030

test: adapt to output change from eb586ed5d8ce Core have a more verbose output on pull. We have to update tests with it. CORE-TEST-OUTPUT-UPDATE: eb586ed5d8ce

compat: fix compatibility with new duplicatecopies Changeset 754b5117622f updated the signature of 'copies.duplicatecopies'. We can now handle the multiple version of that code for compatiblity.

topic: remove 'ass' from the random animal list As much as I love donkey… this generate inappropriate names.

config: stop passing useless default value to config

branching: merge with stable

changelog: add about fixed bookmark and phase handling while changing topics

changelog: add about pager support

pager: add support to `hg evolve --list`

pager: add support to `hg obslog`

pager: add support to `hg topic`

pager: add support to `hg stack`

pager: add a function in compats to start pager This will help us enabling pager when ui.pager API exists. Also we can try plugging in the old pager API in this function and we won't have to change anything.

metadata: cleanup metadata file I'm not sure how this conflict marker survived the pre-publish test run...

branching: merge with stable

topic: remove a silly duplicate in a revset Spotted by Pulkit Goyal. More performance win seems to exists here, but we starts with the obvious.

topics: show changesetcount, troubledcount and headscount by default

topics: use stack.stack() instead of stack.stackdata() stack.stackdata() also calls stack.stack() internally. Moreover if we just want to calculate changesetcount, troubled count, it will be cheap to calculate using stack.stack rather than stackdata().

packaging: mark version as bugfix dev version This avoid confusion when installing non tagged version.

branching: merge with stable

Added tag 6.7.1 for changeset 430ad68292d7

obslog: remove the word "yet" from "No patch available yet" "yet" was a bit confusing as it let me think that patch is currently not available but can be available sometimes later. This is true for cases when it says "context not local" but we have more messages like "no successors", "too many successors", "changesets rebased" where we can't have a patch.

obslog: spell out successor completely If the successor is not known locally, obslog says `succ is unknown locally` which is not a good message. This patch makes sure succ is spelled out completely as successor.

readme: update readme with latest fix (also more the stack one in the right location).

obsfate: make the user list more readable Separate each user in the obsfate user list by a space for readability.

obsfate: fix user filtering in obsfate-printer Only hide current user only if it's the only one that create obs-markers.

obsfate: add a test with user both current and other This will help highlight change in the next changesets.

obsfate: update test The obsfate templatekw and the obsfateprinter behavior was different when displaying or not the current user in obsfate users. Update the test to makes the behavior fix more visible.

packaging: prepare version 6.7.1 The are an important fix on evolve and another important fix for topic performance, let us make a release.

readme: add changelog for topic 0.3.1

add mention of the topic 0.3.0 version

readme: fix evolve 6.7.1 entry

topic: reorder revset for faster evaluation When running the revset on unfiltered repository, the mutable set can get huge. So removing the obsolete changeset first provide a large speedup. This resolve the performance regression we were seeing since the 6.7.0 release.

topics: use stack rather than stackdata when one only wants the changeset count There might be a significant performance impact. Might resolve #309.

log: update obsfate output order Always display successors after the verb. So instead of "rewritten by boris as X", display "rewritten as X by boris". 07b9fcf8b6d3 did update template-based obsfate but forget to update obsfatelineprinter.

test: remove bashism in test-topic-change.t The test was broken on various machine using shell not supporting the `{start..end}` construct.

topics: handle phase correctly while changing topics

tests: add test showing change of phase while changing topic on secret commit

topics: use scmutil.cleanupnodes to create markers while changing topics Earlier if we change topics on changesets with bookmark, the bookmark is not moved to the new changeset as we didn't add that logic and we were creating obsmarkers directly. This patch calls scmutil.cleanupnodes to create obsmarkes which also handles the bookmark movement.

tests: add a new test for testing changing or clearing topics test-topic.t is getting bigger and bigger. This patch introduces a new test which includes test for clearing and changing topics. Since the tests are moved to a new file, this patch, removes those tests from test-topic.t also.

obscache: do not check of argument count of wrapped function After talking with the original author of this check, it appears that it never worked properly, since _readmarkers was always wrapped with @util.nogc.

legacy: rename lookup_errors to not be in all caps (flake8 warning) flake8 has a plugin, pep8-naming, which is not installed by default, but is used if available, no extra config required. This plugin checks names of variables, classes, functions and so on against PEP-8, and it complained about this variable: N806 variable in function should be lowercase Since this isn't a module-level constant, but just a helper variable used only in one function, it's fine to just rename it. With this error gone, flake8 output (used plugins: mccabe, naming, pycodestyle, pyflakes) is totally clean.

randomname: fix the header of the file

topics: move README-topic as hgext3rd/topic/README Before improving the docs about topics, lets move them into the topics folder.

README: move CHANGELOG to a new file

test: small cleanup in test-topic-mode.t remove the mention of "new" (this won't be new soon) and use the official config name.

test: add support for random-all topic mode The 'random' mode no longer generate a random topic for merge.

test: rename test-topicmode to test-topic-mode This is easier to read.

topicmode: add 'random' topic mode That mode will generate a random topic name when the user is about to commit an untopiced changeset.

topic: update the topic-mode hint The hint is now shorter and reference the documentation. That should provide more concise output with more details for user who seeks it.

topic: rename the 'topic-mode' help subtopic This will help making reference to it in warning.

topic: add a 'enforce-all' mode The mode abort for all commit without a topic, even merges.

topicmode: 'enforce' topic mode, no longer warn about untopiced merge merging a topic back in a branch is common case, it seems sensible to not pester the user about it.

topicmode: add new warning topicmode

topic: add documentation for the 'topic-mode' option This should help people to discover it.

test: update tests to use topic-mode enforce

topic: migrate experimental.enforce-topic to experimental.topic-mode

test: adapt to output change from 10e162bb9bf5 The changeset 10e162bb9bf5 in code extend the list of capabilities to include "phases=['heads']" this has a minor impact on test output CORE-TEST-OUTPUT-UPDATE: 10e162bb9bf5

merge with stable

stack: handle basic case of splitting with crash hg stack used to crash horribly whenever a split was encountered. This is no longer the case. If the result of the split (or there successors) produce a sensible linear result with on final head, we can just assume that head is the evolution destination.

tests: update test output with commit 4f969b9e0cf5 in core

tests: update test output with commit ecc96506c49d in core

packaging: update version to match development version This helps avoid confusion when installing from source.

packaging: merge stable back into default 6.7.0 has been released.

packaging: mark stable branch as dev bugfix version This help avoiding confusion when installing evolve from sources.

Added tag 6.7.0 for changeset 3a4f75c6619c

packaging: update debian changelog

packaging: update version number and testedwith version

packaging: mark version 6.7.0 in the source Version ready to be released.

packaging: update compatible version This has been tested with 4.3 too.

readme: prepare readme The feature that only work with 4.3+ are flagged as such.

compat-test: merge future 6.7.0 into 3.8 compat branch (merging through 3.9 compat branch)

compat-test: merge future 6.7.0 into 3.9 compat branch (merging through 4.0 compat branch)

compat-test: merge future 6.7.0 into 4.0 compat branch (merging through 4.1 compat branch)

compat-test: merge future 6.7.0 into 4.1 compat branch (mergeing through 4.2 compat branch)

compat-test: merge future 6.7.0 into 4.2 compat branch Couple feature to disable and other various test impact.

branching: merge future 6.7.0 in the stable branch We are getting ready to release a new version.

topic: fix topic message for mercurial 4.2 and below

README: mention that --age also shows the user While I was here, I fixed the a spelling mistake in previous commit.

topic: try to clarify the "branch" part in stack The idea is to clarify the meaning of "behind" with using the "target" word.

readme: mention the message update

topics: make sure user don't pass both the age option and a topic name

topics: spell out topics completely in help

topics: show the user who last touched the topic in --age This patch adds support for showing the user who last touched the topic in the age option to `hg topics`.

topics: initialize variable with default value instead of assigning later

topics: improve the function signature by accepting arguments as **opts

topic: merge with strip related fix

topic: skip topic movement message during strip During strip transaction the repository is not in a great state. It is simpler to skip the computation entirely.

topics/ui: detect and signal when an empty changeset becomes non-empty

topics/transaction: return immediately if we are in the middle of a transaction

topics/ui: signal when an operation entails voiding a topic Typical situations may include: * publish * push (to publishing server) * pull * fold

topics/ui: signal when the topics command creates a new (empty) topic

topics: signal to the end user when a topic has been forgotten Situation is: * we're updating outside an empty topic. * we've cleared topics

topic: add a --topic option to "outgoing" command By symmetry with "push" in the previous changeset.

topic: add a --topic option to "push" command This is symmetrical with --bookmark or --branch; it selects changesets in specified topic as revisions to push.

test-compat: adapt to core change in b90bd9a98c8b Blackbox just got a little more chatty.

readme: update about obslog update and documentation refresh

topic/tuto: be more precise in the top introduction about the publishing server Indeed there is a chapter with a non-publishing one.

topics/tuto: prefer rebase over merge and remove the weird merge attempt

topics/tuto: typo fix and s/multiple/two

topics/tuto: be more complete over the de-orphaning action within a topic

topics/tuto: try to be more precise on why `hg log` output is hairy

topics/tuto: attempt to have a slightly more clear wording

topics/tuto: try to be more clear when explaining previous/next

test: fix the enforce-topic configuration There have been an error while updating this patch.

topics/tuto: clarification on the scope of the tutorial Also we try to remain the reader that push -> publish.

topics/tuto: slightly more verbose explanation of what we are seeing

topics/tuto: spell out `hg topics` entirely

topics/tuto: activate the `enforce-topic` option This really help users to stick within topics.

topics/tuto: highlight the behaviour on publish + update And the fact that empty topics vanish if we update out of them.

topics/tuto: fix title underline type introduced earlier

doc: update graph with latest version of doc-graph

flake8 docs/conf.py

doc: disable generating command documentation when mercurial is not up-to-date

doc: add documentation for evolve commands By using a sphinx directive that call `hg help`.

doc: clarify undocumented features

test2rst: ignore the #if/#endif line in the output They are not useful for the rest.

doc: integrate graphviz graphs in tutorials Use the mercurial-docgraph extension (https://pypi.python.org/pypi/hg- docgraph/) in tutorials in order to have some dot graphs in the tutorials .t files. Then generate the doc as usual, the sphinx-graphviz extension (http://www .sphinx-doc.org/en/stable/ext/graphviz.html) has been added and it should handle the generation of the graphs. Please be aware that you need the dot binary installed in your system. Please refer to the extension documentation for more configuration.

doc: add a special flag for content to ignore in the rst The testfile to rest document convertion has a new way to ignore some commands.

obslog: simplify formatter keys The formatter field keys are all prefixed with `debugobshistory.'. This is annoyingly useless as they are already in the `debughistory` topic. This patch simplify these keys. For examle, on this repository `hg obslog -Tdebug -r 31cbace4c0f1` : ``` debugobshistory = [ { 'node':'31cbace4c0f1', 'shortdescription':'topics: make sure we have some restrictions on topic names', 'rev':2904, 'markers':[ ] }, { 'node':'d439a6087434', 'markers':[ { 'date':(1504176329.83902, -7200 ), 'verb':'rewritten', 'succnodes':[ '31cbace4c0f1' ], 'effect':[ 'parent' ], 'user':'Pierre-Yves David <pierre-yves.david@octobus.net>' } ] }, { 'node':'1e1f651704d4', 'markers':[ { 'date':(1504175088.811924, -7200 ), 'verb':'rewritten', 'succnodes':[ 'd439a6087434' ], 'effect':[ 'parent' ], 'user':'Pierre-Yves David <pierre-yves.david@octobus.net>' } ] }, { 'node':'eb6495cf6cb1', 'markers':[ { 'date':(1504015275.001643, -19800 ), 'verb':'rewritten', 'succnodes':[ '1e1f651704d4' ], 'effect':[ 'parent', 'content' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, { 'node':'761e446e0112', 'markers':[ { 'date':(1504015201.780276, -19800 ), 'verb':'rewritten', 'succnodes':[ 'eb6495cf6cb1' ], 'effect':[ 'content' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, { 'node':'531a626950bd', 'markers':[ { 'date':(1504015017.897054, -19800 ), 'verb':'rewritten', 'succnodes':[ '761e446e0112' ], 'effect':[ 'meta', 'parent', 'content' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, { 'node':'c2f9ba7329ea', 'markers':[ { 'date':(1504014136.876537, -19800 ), 'verb':'rewritten', 'succnodes':[ '531a626950bd' ], 'effect':[ 'meta' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, ] ``` We now able to ask `hg obslog -r 78debdfb3e4d -T '{label("log.summary", shortdescription)}\n{if(markers, markers % " {date|age} {user|person}\n")}'` ``` doc: simplify the reference to in-core features 9 days ago Pierre-Yves David 9 days ago Pierre-Yves David 9 days ago Pierre-Yves David 9 days ago Pierre-Yves David 9 days ago Philippe Pepiot 9 days ago Philippe Pepiot ```

obslog: fix `--template` with `--graph` option The `template` option was not propagated.

obslog: uniformize `_debugobshistoryrevs` and `_debugobshistorygraph` arguments `_debugobshistoryrevs` and `_debugobshistorygraph` perform quite the same action, the latter simply add graph support. Consequently, it looks better for them to have the same argument list.

obslog: fix --patch with --no-graph options The repo given to _debughistorydisplaymarker which computes the diff was filtered when graph mode is disabled.

commands: upgrade pdiff and pstatus to full commands Doing so make them appears in the documentation, improving their discoverability.

gup/gdown: properly mark these commands as deprecated They are no longer displayed in the documentation.

Backed out changeset 1b4c92621e23 This got published by mistake.

doc: integrate graphviz graphs in tutorials Use the mercurial-graphviz extension (https://bitbucket.org/octobus/mercurial_graphviz) in tutorials in order to have some dot graphs in the tutorials .t files. In order to run the tests, export the GRAPHVIZ_EXTENSION variable which points to your copy of the extension. Please be aware that pygraphviz should be installed in your environment. That should be sufficient for generating dot graphs in text format. Then generate the doc as usual, the sphinx-graphviz extension (http://www .sphinx-doc.org/en/stable/ext/graphviz.html) has been added and it should handle the generation of the graphs. Please be aware that you need the dot binary installed in your system. Please refer to the extension documentation for more configuration.

amend: lift the --interactive constraint on `--extract` The uncommit logic now supports interactive selection.

readme: mention the topic output cleanup

readme: mention the new --interactive mode for uncommit

uncommit: minor comment cleanup in the test Fix some of the sectionning and fix on comments.

uncommit: small cleanup of the interactive test setup

tests: add tests for interactively uncommitting by mentioning files

uncommit: fix the dirstate handling in `uncommit -i` This patch fixes the dirstate handling after `hg uncommit --interactive`. This patch is bit verbose about the logic and efforts are not put to plug the logic into existing logic as it's easier to understand like this. Plugging this into non-interactive logic deserves a separate patch.

uncommit: pre-indent a block in if-True The block will be moved in if-else in next patch.

uncommit: add an interactive option to uncommit This patchs adds an interactive flag to uncommit command which lets you choose hunks interactively. The implementation is as follows: 1) prompt user to select hunks to uncommit interactively 2) make a temporary commit of the hunks user selected 3) calculate the diff of temporary commit and changeset to be uncommitted 4) commit that diff which results in the changeset which should be there after uncommiting 5) create obsmarkers as required, phases and bookmarks handling 6) reroute the working directory

uncommit: pre-indent a block in if-True for the next patch

topic: provide more information when behind count cannot be computed The behind count has been confusing for various user and the associated error message is even worth. We try to clarify it to see if that helps.

topic: show the t0 even if topic is not yet touched

topics: improve the description if topic is not touched Instead of an empty stack in `hg stack` when topic does not contain any changeset, we show `not yet touched`.

topics: show working directory branch when topic is empty

topics: add tests for cases when a topic is empty

readme: mention compatibility with future 4.4

topic: update the message used with --age for empty topic This clarify things when a topic got emptied by publishing.

sharing: edit pass

user-guide: edit pass

topic: stabilise the output of --age when date ties We just needed to introduce sort to stabilize the output order.

tests: update after removing of redundant amend commit Following e8a7c1a0565a, temporary amend commits has been removed impacting all revision numbers in tests including amend operations. Update tests case to use description or hashes when possible and update revisions number when not.

topic: setup 'topic' value for working ctx The way amend work in core change in e8a7c1a0565a. The intermediate commit disappear and we can no longer rely on it to carry the topic value to amend. To fix this, we ensure the current topic value can be retrieved through the `workingctx.extra()` value. Since there is no way to carry a "missing" key information in a way that survives and "dict.update" call. We also has to introduce hacking behavior about a special empty value for topic.

tests: abstract version number for test-topic-stack.t Using explicite version number always bring trouble, this is why we have unique description that can select changesets.

evolve: use registrar.templatekeyword to register template keyword functions Now, using registrar.templatekeyword of Mercurial directly in evolve extension should be safe enough. because it has been available since Mercurial 3.8, and minimum Mercurial version for evolve extension is 3.8, too. BTW, this also fixes an issue of "hg help templates" output that template keywords "precursors" and "successors" are not displayed as same as others, because they do not have ":KEYWORD:" prefix in their docstring.

evolve: use registrar.revsetpredicate to register revset predicate functions Now, using registrar.revsetpredicate of Mercurial directly in evolve extension should be safe enough. because it has been available since Mercurial 3.8, and minimum Mercurial version for evolve extension is 3.8, too.

topic: use registrar.revsetpredicate to register revset predicate functions Now, using registrar.revsetpredicate of Mercurial directly in topic extension should be safe enough. because it has been available since Mercurial 3.8, and minimum Mercurial version for topic extension is 4.0. This patch also removes modsetup() in topic/revset.py, because it is useless. BTW, this patch fixes an issue of "hg help revsets" output that custom revset predicates are not displayed as same as others, because they are not "inline literal" in reST syntax (``NAME``).

doc: make paragraphs before example code end with "::" for reST syntax This prevents lines in an example code from being treated as a part of normal paragraph. For issue example, lines are folded into one paragraph.

topic: centralize compatibility logic between hg versions into compat module This patch can delay loading obsutil and obsolete modules until they are actually used at "hg topics" or so, if demandimport of Mercurial is enabled.

readme: mention the improvement to stack in the readme

test: issue a clarifying graph print in tests/test-stack-branch.t

stack: properly order stack when gaps existing inside it We transitively search for the next "stack" ancestors, of changeset in the stack not based on other revision of the stack. This should help having a consistent display when topic are interleaved.

stack: display both parent with displaying merge This will help understanding merge in the stack. More test involving merge are adding in the next changeset.

tests: add tests for showing stack when merge is involved This patch adds tests of showing stack when merges are involved. This will help us in changing the behaviour and realising that in later patches.

stack: move data computation on the object We gather multiple data about the stack on the object. Let us move this on the object and keep it cached there.

stack: replace 'getstack' with direct call to 'stack' The dedicated function do not add any value. We can update all the callers.

stack: introduce a rich stack object The logic around stack object become more and more complex. We great and object to gather and abstract it.

tests: add tests for `hg stack` showing surprising behavior with gaps The test will help us to analyse in next commit if the things are fixed or not.

topic: check availability of obsutil.getmarkers() for portability Before this patch, topic extension causes unintentional failure with Mercurial earlier than 4.3, because obsutil.getmarkers() has been available since Mercurial 4.3 (tests for topic on mercurial-4.* branches fail, too). This breaks "minimumhgversion = '4.0'" declaration of topic extension. This patch fixes this issue in a straightforward way for simplicity on stable branch. I'm planning to centralize such portability logic in topic extension into topic/compat.py or so on default branch for efficiency at runtime, like as evolve/compat.py.

tests: add more explicit test about empty topic from publishing

convertbookmark: advertise the new command in the readme The command is in a good enough shape now.

convertbookmark: properly convert stacked bookmarks We ignores pure descendant when looking for revision to convert. This adds support for cases were a linear stack contains multiple bookmark (or un-bookmarked descendants exists). In this case, some changeset are left orphan, but we'll consider the issue as minor for now.

convertbookmark: perform all actions at the end This will make the whole operation more deterministic and robust.

converbookmark: split target computation from actual update This will allow for further refactoring helping consistency.

convertbookmark: extract the revset into a module level constant This will make it easier to read and modify the query.

convertbookmark: properly exclude public changeset Public changeset are immutable and cannot have a topic anyway.

test: add a new root changeset to all debugconvertbookmark test case We'll make this root changeset public to check the debugconvertbookmark logic in that regards. It is added in its own changeset since it massively impact all output.

tests: import section in 'test-topic-debugcb.t' We now have two levels of titles to clarify some aspect of the tests.

test: avoid using debugdrawdag in 'test-topic-debugcb.t' The 'debugdrawdag' utility adds local tags that prevent hidden changeset to get hidden. We will do without that extension for now.

tests: add more tests for debugconvertbookmark

convertbookmark: add logic to skip revisions with multiple bookmarks When a user tries to converts a bookmark to topic which is on a changeset with more bookmarks we skip that.

topics: add a new debugconvertbookmark command to convert bookmarks to topics This new command, aliased to debugcb converts bookmarks to topics. This command either accept name of a bookmark using flag '-b' or '--all'. If a bookmark is passed using '-b', the whole stack defined by that bookmark is converted to topics. If '--all' is passed, the above thing is repeated for every bookmark in the repository. If the revset which we are using unable to decides revisions of the stack and return an expty set, in that cases we are not deleting the bookmark as we are not writing any topics of the same name as that of bookmark. Also currently if a changeset has two bookmarks, than there is buggy behaviour. So these are known lackings in the current implementation which will be fixed in upcoming patches. This also adds tests for the same.

topic: support --rev argument and properly process then as user input Revisions inputed by the users should be processed using `scmutil.revrange`. This will take alias into account and allow extensions to monitor the user inputs. As a side effect, the '_changetopics' function takes revisions as argument. make the API clearer.

topic: move a status message in the right scope The finally get runs on failure so we should not advertise rewrite topic in the case. In addition the 'rewrote' variable can be undefined in the finally.

obsfate: use effect flag information for computing a better verb

compat: make it more clear that evolve need Mercurial >= minversion The message is more clear when mercurial isn't installed at all.

doc: record all the missings and strange bit we know We know the doc is not as fresh as it could be. We make sure the reader is aware too.

directaccess: fix with tree without order 1b28525e6698 removes order from tree, changing the indexes in gethashsymbols. Fix that

compat: adapt to test output changes different access pattern in 4.4 means different results. Make evolve works with mercurial core 72b5f4d53c58

compat: adapt to rebase change in coming 4.4 Make evolve works with mercurial core 72b5f4d53c58

topics: import lock as lockmods We'll need a 'lock' variable in the next changeset. we move the module out of the way ahead of time for clarity.

topics: make sure we have some restrictions on topic names This patch makes sure we don't allow topic names with just whitespaces, and other checks which we do for a bookmark.

topic: add test showing no restrictions on topic names Currently we don't have any restrictions on topic names and each of the topic name works. We want them to not work as some of them are used internally and only integers can be rev numbers too.

index: edit pass by native english speaker

topic: reword and simplify explanation of "behind"

topic: tutorial grammar fixes

doc-front-page: link to the changeset evolution section in the document The section is unlikely to be perfect, but at least it exists.

doc-front-page: use a clearer statement about the experimental status This text comes form the Mercurial wiki.

doc-front-pagE: add a paragraph about "why the extension" Let us clarify why there is an extension in the first place.

doc-front-page: expand the paragraph about changeset evolution We clarify the part of the explanation about the changeset evolution concept.

doc-front-page: rename the "next step" section This are pointer to relevant section in the doc. It is a bit double usage with the table of content. We at least clarify the title.

doc-front-page: mention that "Changeset Evolution" is a specific concept It will get it own paragraph soon.

doc-front-page: include the index in the TOC This will help important content to stand forward.

doc-front-page: add a title to the part about the extension We'll rework this section more in depth, but I would like it to have a title first to have it show up in the table of content.

doc-front-page: add a feature summary at the beginning of the page

doc-front-page: mention the mailing list in the documentation It is an important tool to keep people up to date.

doc-front-page: move installation instruction earliero This is important for user.

doc-front-page: move introduction before the table of content This should make a friendlier landing.

doc: simplify the reference to in-core features This should do the whole thing lighter.

doc: be less dramatic about changeset immutability Quoting Phillipe: "This is not a Tolkien Novel".

doc: clarify the introduction sentence

topics: allow use a --current when setting a topic This patch allow to use the current flag which can be used by user set existing revs to the current topic.

topic: make --clear + topicname invalid The two flags are mutually exclusive.

topics: add a current flag to display current topic This patch adds a current flag which can be used by user to display the current topic.

topics: add a missing trailing comma on list of flag This will make the next changeset easier to read.

doc: let mercurial find where evolve is installed

doc: use pip to install evolve

doc: reword "target repository" to "remote repository"

doc: typo fixes

doc: use "hidden" instead of "invisible"

tests: add whitespaces in test-topic.t to make it more readable

evolve: undo change from "divergent" to "phasedivergent" for --divergent Looks like an accidental update in feaa52680682 (log: bumped was renamed into phasedivergent, 2017-08-10).

messages: use hyphenated '{phase,content}-divergent' in user messages The hyphenated version is more readable and it's what we use the {instabilities} template.

warning: use 'divergent', not 'contentdivergent' on old Mercurial This was just an oversight in f6517779a7c4 (warning: rename warning message, 2017-08-24).

warning: rename warning message divergent has been renamed into contentdivergent. Use their renamed counterpart in warning message for new unstable changesets. Renaming done according to https://www.mercurial-scm.org/wiki/CEDVocabulary

warning: rename bumped warning message bumped has been renamed into phasedivergent. Update the warning message when new phasedivergent changesets are detected. Renaming done according to https://www.mercurial-scm.org/wiki/CEDVocabulary

warning: rename unstable warning message unstable has been renamed into orphan. Update the warning message when new orphan changesets are detected. Renaming done according to https://www.mercurial-scm.org/wiki/CEDVocabulary

test: fix output of test-discovery-obshashrange.t The username is now quoted in the output.

obscache: use _readmarkers() from core with correct signature The copied _readmarkers() went stale with Mercurial core commit 5d3ba4395288 (obsstore: let read marker API take a range of offsets, 2017-06-04). At the same time, the Mercurial core version of the function gained the desired offset argument, so we can now use that function.

topics: take locks and start transaction before calling _changetopics This will help us in calling _changetopics in other transactions which already started. Currently the _changetopics creates its own transaction and hence can't be used it a same transaction with any other function or logic.

compat: fix instabilities compat We added an instabilities method for old version of Mercurial. But we returned an old value for orphan changesets, the one before the big evolve renaming. Fix the return value to match the new return values.

readme: mention the documentation update

topic: make command names valid as expected, even if ui.strict=true Before this patch, "hg topics" and "hg stack" cause unintentional "unknown command" failure, if ui.strict=true. In such case, "topics [TOPIC]" and "stack [TOPIC]" are required as a canonical name, because synopsis-like string is used as command name pattern of @command annotation for them. This patch also specifies additional "synopsis" for @command annotation, for intentional output in online help of these commands.

branching: default into stable It is time for a new release

compat: handle pre-4.2 compatibility for accessing vfs The vfs module is quite new.

compat: avoid using configoveride This not supported before mercurial 4.1.

compat: use old style method to update bookmark The '_del' and '_set' method are new additions in 4.3 we should not use them in the compatibility layers.

topic: wrap 'update' in a more flexible way This ensure compatibility with mercurial 4.1 and below

branching: open the mercurial 4.2 compatibility branch The freeze as started.

readme: add an entry about the unified message

touch: use precheck to validate revision This gives us standard check and standard error message.

prune: use precheck to validate revision This gives us standard check and standard error message.

uncommit: use precheck to validate revision This gives us standard check and standard error message.

amend: use precheck to validate revision This gives us standard check and standard error message.

split: use precheck to validate revision This gives us standard check and standard error message.

precheck: handle rewrite attempt of nullrev This is a common breaking case, so we handle and test it in the generic code.

precheck: update the orphan message to something me generic This will help to reuse it for other commands.

precheck: point to the instability doc when aborting This will help user to understand what is going on.

evolve: document the various instability/troubles We need something to point people at.

precheck: also check for unstability creation

prefetc: point at the offending changeset when aborting We do our best to display comptact but usable information.

precheck: point to 'phase' help when aborting some of the error message already does that. It seems a good idea.

precheck: use 'changesets' in the message instead of 'revisions' This match the message `hg commit --amend` issue in core.

rewriteutil: add a precheck function to validate rewrite beforehand For now this only checks for changeset mutability and this is only used by 'checkfold'. We'll expand the checking and usage as we go.

test: remove reference to the graphlog extension The feature is in core for ages.

test: use common setup for test-split.t This make things cleaner.

split: compute revision to split after locking This would avoid strange behavior from race condition.

split: basic code cleanup We remove a useless extra variable since another one already hold the same value.

commands: rewrite the 'evocommands' module to 'cmdrewrite' The remaining commands should get their own module, so we rename the module for clarity. We update the module comments to better fits its purpose.

split: add support for the -D and -U option

split: fix the --user option The option ended up being ignored.

metaedit: add support for the -D and -U options

fold: add support for the -D and -U options

test: extract most fold testing into a test-fold module

commands: move 'prune' to the 'evocommands' module

rewriteutil: move 'deletebookmark' to the module

rewriteutil: move 'reachablefrombookmark' to the module

commands: move the touch to the 'evocommands' module

commands: move split to the 'evocommands' module

commands: move fold to the 'evocommands' module

commands: move metaedit to the 'evocommands' module

rewriteutil: move the 'rewrite' function

rewriteutil: move 'foldcheck' to the new module

rewriteutil: move disallowednewunstable in the new module

rewriteutil: create a rewriteutil module to host utility function The ultimate goal of this module is to gather basic building block for rewriting changesets. This is aimed at moving into core and being use by the core extension.

interactive: fix the interractive option import The move made in e6bc6eaa17c5 was buggy.

test: update test output to match b11e8c67fb0f hg debugobsolete now issues a message about the obsoleted changesets.

test: update test output from b47fef6d2365 We run this check for bundle1 too now.

compat: add a compatibility layer for bookmark move The API was updated in 4.3 (712a85b3677f) we adapt to that.

compat: use 'safehasattr' over 'hasattr' 'hasattr' is broken in python 2.

stack: show short node of changesets in `hg stack -v` After this patch, hg stack -v shows short nodes for changesets which have topic index, i.e. excluding the bases except t0.

compat: use 'repo.cachevfs' when available In 4133c0b0fcd7 (core), the repository gained a new vfs dedicated to caches. We update the code to follow this new pattern.

debugobsconvert: take the lock when writing the obsstore file We were upgrading the store unprotected.

topics: add a test demonstarting sorting of topics by time using --age

branching: merge with stable

prev: allow to update to 't0' from 't1' When on the first changeset of a topic, one can move back one changeset to end up on t0. The new working copy parent to not belong to the topic, but the topic is still active. The next commit will create a new root to the active topic. You can get the same result using `hg up t0`

topic: add a 'topicidx()' to context This will be useful for the `t0` logic in `hg prev`

prev: retrieve the 'no-topic' result is a clear and reusable option We'll use it more, so let us make it pretty first.

prev: add '_getcurrenttopic' helper and use it We'll add more spot where this information is used.

prev: explicitly use 'p1' as a variable name This make the code clearer.

topic: rename the internal topic option we'll use it more widely so I give it a more generic name. It is an internal option so not wories regarding compatibility.

prev: extract the code computing the destination This make the handling of the result simpler. The test agree as one return code is fixed.

prev: issue a proper error when reaching repository root (and adds the associated test)

prev: stop creating a repository at the root of 'test-repo.t' We run the test in a subdirectory now, this usually avoid various kind of future issue.

prev: extract the function performing the update That code is fairly independant so let us isolate it to simplify the rest of the code.

prev: simplify the bookmark preserving logic We can use 'None' as a special value and have a simpler code.

prev: rename 'p' to 'target' This makes the code clearer.

topics: check for topic on commit before a user enters message We have a enforce-topic cofig which can forbid user to commit without a topic on it. We used to check topic on a commit after the user enters message, but we should fail early.

packaging: update readme I forgot again.

topics: add a new flag --age which will show last touched time for topics This adds a new flag `--age` to `hg topic` command which will show topics sorted by their last touched time and will also show the last touched time for them. This patch also adds a simple test to make sure the flag does not breaks by future changes. Adding more tests showing output like "3 hours ago", "2 minutes ago" etc will change as the code takes time.time() into account which will increase with time, and hence the output will change, so we need some static output like a date.

uncommit: expose the feature with a '--extract' to amend The name of the "uncommit" feature have been an ongoing issue, but no better name have been found in the past year. We try another approach by exposing the 'uncommit' feature directly in `hg amend`. The command will not be able to do both operation a the same time (add new change to the commit + extract should change, but this is already the case with the two command today.

uncommit: add support for -U and -D

uncommit: add support for --user and --date This is also long overdue

uncommit: add support for --message and --logfile This is long overdue.

amend: drop the implementation details from the user help This is not relevant to users.

uncommit: move to the 'evocommands' module We are about to play around with a UI mixing amend and uncommit, we take advantage of this to split the __init__.py module a bit more.

amend: extract into a 'evolve.evocommands' module We are about to play around with a UI mixing amend and uncommit, we take advantage of this to split the __init__.py module a bit more.

test: handle output change in 20f533a92eda The bundle backup name has changed.

tutorial: fix grammar and spelling

tutorial: word wrap long lines

tutorial: use rm instead of 'hg rm' for an untracked temporary file

readme: update with various topic improvement

topics: add a config knob to forbid untopiced commit After this patch one can add the following to their hgrc to stop allowing new commits with no topic on it. [experimental] enforce-topic = yes

topics: update the help for `hg topics` describing ways to use the command

branching: merge with stable

obshashrange: add cache warming instruction to the documentation

evolve: explain how to disable markers discovery in the documentation This is useful for large repository.

obshashrange: add cache warming instruction to the documentation

topics: add t0 and b0 to the stack t0 or b0 will be the base of the stack and it's the parent of t1 or b1. The cool thing about this is that if you update to t0 using `hg up t0` or do `hg prev` on t1, you will be updated to t0 with the current topic preserved. This patch adds t0 to stack and implement the preserving topic case for t0 while using `hg update`.

topics: wrap the update function to check if either t0 or b0 is passed as rev t0 or b0, seriously, what's that. Do they even exist? Hold on and look for the next commits what we are trying to do.

compat: adapt to change in 53b3a1968aa6-core

compat: merge with stable Nothing to report beside the drop of the obsfate related tests.

evolve: preserve the branch of the original changeset when evolving merge

merge: default into stable to prepare next version Let us prepare ourself for 6.5.0

obslog: handle patch generation for mercurial 4.1- The unidiff API changed, we detect and work around that.

topic: also have the revbranchcache during the discovery

topic: cleanup the repository wrapping logic in topic discovery We are know overriding the class so we do not need to update and restore the pushop itself.

topic: adapt to function migrate to obsutil Mercurial 4.3 has a new module "obsutil" and multiple functions moved there. We handle the move for the one we care about.

evolve: adapt to function migrate to obsutil Mercurial 4.3 has a new module "obsutil" and multiple functions moved there. We handle the move for the one we care about.

topic: directly use the '_notpublic' revset This is just more robust to achieve the same goal.

topic: drop the message about running evolve after topic change Topic change is no longer creating a mess that needs cleaning.

template: handle lack of "users" in the obsfate data This can happens when their are no markers (or the markers has no user data?)

doc: update effect flag documentation

obsfate: override the default log output Override the default log output by showing obsfate if not empty.

evolve: fix documentation formatting The config example were formatted as standard paragraph.

compat: fix topicset for mercurial 4.1 The 'getrevset' method is not available there.

obsfate: refactor obsfate data computing Refactor how obsfate data are computed in order to reuse this logic later when hooking on default log output.

topic: exclude public and topic changeset from branch stack Stack use-case is to show the current work in progress, which are symbolized by the phase draft and secret phase. Moreover showing public changesets in stack output when displaying current branch would display a lot of changesets for long-lived branches and would be quite useless. We also exclude topic changeset form the stack since they already exist on their own stack. getstack revsets didn't needed update when displaying a topic as when a changeset become public, its topic is no longer relevant.

tests: use a more portable form for new lines

topic: don't abort if there is no current topic in stack() revset Named branches support has been added and we should not abort if there is no active topic.

topics: return a parse error if stack() revset is passed with argument

tests: add test to show topics working with shelve

topics: update current topic to the topic of newly rebased commit (issue5551) The rebase code passes branchmerge equals to True while updating to the rebased commit. We need to make sure topic is preserved even after rebase and hence we need to update the topic even when branchmerge argument is set to True. But there is a twist in the tale, merge also uses this part of code and we allow to update topic when brancmerge is True, in merge cases the topic after merge will the topic of the destination commit, not the topic of working directory parent. So we need the function to have information about whether a rebase is going on, and we do it by wrapping the rebase command and storing some value in the config. This is a bit hacky but works for now. This patch fixes issue related to loosing of topic while rebase. Thanks to Boris Feld for the rigourous tests.

docs: some fixes to the help text

topics: pass 'topics' to ui.formatter instead of 'bookmarks'

topic: also insert the extra head check with using the new head checking This will get the protection in place in all cases.

topic: some document for an obscure function

topic: adjust head checking wrapping to not interfere with concurrent push In the previous form, the new topic head was detected as affected and the push was rejected. We introduce a of 'test-topic-push.t' using the new race checker as there have been many compatibility issue with this new checkers.

topic: also detect head checking using the concurrent part

test: avoid 'test-check-commit.t' complaining copied code We switch to git diff.

topic: small test cleanuo The section was repeated.

topic: move the heads data to the branch line when appropriates The topic line is dropped as it is quite confusing.

topic: add some initial support for using stack on named branch Stack is a useful command that can make sense in other context. The current support is hacky and awful, but we have something!

topic: explicitly pass topic as a keyword argument This clarify all callers before adding more logic related to bare branch in stack.

topic: makes split keep the topic Refactor split to extract the preparation of the working directory in a separate function. This helps topic wrap this function to save topic before update and restore it after preparing the working directory just before the split.

topic: add tests for fold behavior with topics Clarify the fold behavior for keeping topics.

topics: pass quietempty=True to suppress useless output while changing topics This will help in suppressing the output "0 files updated, 0 file removed, ..."

topics: return early so that other if conditions don't get execute (issue5600) We were not returning after the _changetopics() call and hence the if's below it were also executed which resulted in changing of current topic. This prevent current topic to be updated even when we only affect changeset unrelated to the working copy. Not that the rebase output change as it expose a new bug (rebased changeset gain a topic)

test: extra output to understand the next changeset better

topics: move the logic to change or clear current topic into a new function It adds a new _changecurrenttopic which changes or clears the current topic.

tests: expand output to check topic activation This will help understanding later changesets.

branching: merge stable into default

split: preserve author of the original changeset in the successors Previously, the new changesets were authored by the default user.

grab: properly quote hg executable in the alias Breakage has been reported on Windows.

topic: improve the revset used to return name->nodes mapping The 'topic' version already filters public changeset out, and skipping 'changectx' creation will helps performance.

topic: update the changectx method to respect phases The topic is no longer returned once the changeset is no longer mutable (unless explicitly requested).

topic: avoid crash when topic is loaded but not enabled for a repository

compat: update test to match core default state This output changed in 560ceb654180.

topicmap: massive rework Massively rework the way we build and use topicmap. This bring massive performance benefit. Topic map use to be a fully independant thing that we would switch on and off globaly. The caching on disk was broken so the performance were atrocious. Intead, now the topic are inherited from the 'immutable' map. We gave up on storing them on disk for now since the mutable set is usually small enough. The activation is done by hacking new "filter" on the repository and detection when they are one. This is hacky but core is hard to wrap here. Overall this whole wrapping is really scary and we should massage core API to help it.

topic: use the 'topic' revset in namespace This revset performance just got improved.

topic-revset: update the revset to no longer build changectx Atribute access is expensive, and changectx are very expensive to build, so we skip these for better performance. Before: ! wall 0.012195 comb 0.020000 user 0.020000 sys 0.000000 (best of 217) After: ! wall 0.008816 comb 0.010000 user 0.010000 sys 0.000000 (best of 303) (Before this changeset parent) ! wall 0.213261 comb 0.210000 user 0.210000 sys 0.000000 (best of 45)

topic-revset: changectx creation in the revset The current mutability filter is very expensive, we use a more direct and efficent way to do so: Before: ! wall 0.213261 comb 0.210000 user 0.210000 sys 0.000000 (best of 45) After: ! wall 0.012195 comb 0.020000 user 0.020000 sys 0.000000 (best of 217)

topics: add some noise to rewrittent changeset to prevent hash cycle If we have a changeset with topic `x`, we change it's topic to `y`, fine. When we change it's topic back again to `x`, we get the hash of the the obsoleted changeset which had the topic `x` initially. The same happens for few more cases like clearing the topic of a changeset which initially had no topic. This approach is influenced from cmdutil.amend and other commands (rebase, histedit, etc…)

topic-change: update the working copy along when changing topic of '.' This avoids leaving the working copy behind, removing another large parts of issue5441.

topic-change: cleanup the locking and transaction mechanism The previous code did not garanted we would release all lock (and was a bit more complicated than needed.

topics: use a dict for successors of changesets produced by topic change This patch adds a dictionary to store the successors of changesets which got obsoleted when we change it's topic. This is an improvement in the fix for issue5441.

topic: further simplify the clear logic We just set 'topic' to None and the rest should follow.

topics: drop the clean argument from _changetopics() After this commit, None will represent that we want to clean the topic.

topics: rename '--change' flag to '--rev' flag The --change flag was used to read a revset of which topic should be changed. In mercurial we use --rev for this type of flag. Now things will work as follows: `hg topics topicname`: It will set the current topic `hg topics topicname --rev revset`: Change topic of all the revs in the revset to topicname Further patches will try to achieve the following: `hg topics --clear --rev revset`: clear topic from all the revisions in the revset `hg topics --clear`: clear the current topic (Current behavior) `hg topics --rev revset`: show topics on the revisions in the revset

topics: factor out the logic to change topic in a new function It will help to refactor and fix bugs. Moreover we can re-use the logic.

obslog: update the readme This is release not worthy

obslog: add a comment about the final new line of descriptions

obslog: also display description patch with --patch When activating the --patch option, also display the description patch.

obslog: extra patch indentation code The code is simple and we need to reuse it.

obslog: add a patch option Add support for '--patch' option in obslog for a similar effect than "hg log --patch". The patch support is only limited to a few basic cases that will be extended in the future.

obslog: clarify some sorting code I'm not sure why Boris did it, but this belong to the next patch.

obslog: pass directly unfiltered_repo _debugobshistorydisplaynode used to create two times an unfiltered repo, makes _debugobshistoryrevs create only one unfiltered repo and pass it directly.

obslog: remove useless repo arg _debugobshistorydisplaymarker used to takes repo as an argument but it isn't needed anymore.

obslog: small renaming of _debugobshistorysingle Rename _debugobshistorysingle to _debugobshistoryrevs in order to better reflect its purpose.

refactoring: directly use 'ctx.unstable()' in showstack function This is simpler and more efficient.

packaging: flag default as version 6.5.0.dev This helps to reduce confusion when installing intermediate version.

merge: get stable change back into default

obsfate: improve obsfate output Improve obsfate output: * Remove newline and replace it by '; ' * Improve the hybrid object for making join(obsfate, '|') working.

packagin: mark stable branch as 6.4.1.dev This help prevent confusion with installing intermediate version

topics: abort if user wants to show the stack of a non-existent topic

stack: show unstable state for the current revision if it is one (issue5553) Before this patch if the current revision is unstable, hg stack does not show the unstable state. This patch fixes that by showing both current and unstable state for the current revision if that's unstable.

topics: some minute fixes to the documentation which shows up in help I am not a native but these changes are simple and obvious.

topics: make sure we commit on new parents while changing topics (issue5441) While changing topics of a set of linear commits, we used to commit our new changesets with new topic on parents of its predecessor i.e. changeset before the topic change. If the topic of parent was also changed, that parent will become obsolete and hence resulting the cnew commit in unstable state. For a set of linear commits this repeats and we end up in a tree state as mentioned in the bug. This patch fixes the bug by checking whether the parent was obsoleted and if yes, commit on the new parent.

tests: add a test to show issue5441 in test-topic.t The issue will be fixed in the next patch and the test will be helpful to show that.
