tersestatus: make methods part of the dirnode class Differential Revision: https://phab.mercurial-scm.org/D1042

tersestatus: re-implement the functionality to terse the status The previous terse status implementation was hacking around os.listdir() and was flaky. There have been a lot of instances of mercurial buildbots failing and google's internal builds failing because of the hacky implementation of terse status. Even though I wrote the last implementation but it was hard for me to find the reason for the flake. The new implementation can be slower than the old one but is clean and easy to understand. In this we create a node object for each directory and create a tree like structure starting from the root of the working copy. While building the tree like structure we store some information on the nodes which will be helpful for deciding later whether we can terse the dir or not. Once the whole tree is build we traverse and built the list of files for each status with required tersing. There is no behaviour change as the old test, test-status-terse.t passes with the new implementation. Differential Revision: https://phab.mercurial-scm.org/D985

context: add is `isinmemory()` to filectx This will make it easier to skip certain behavior when running an in-memory merge. Differential Revision: https://phab.mercurial-scm.org/D1061

merge: ensure that we always commit the mergestate In future patches, we may halt the merge process based on configuration or user requests by raising exceptions. We need to ensure that the mergestate is unconditionally committed even when such an exception is raised. Depends on D930. Differential Revision: https://phab.mercurial-scm.org/D931

merge: add tests to show current behavior on failed filemerges Currently, failed file merges will nevertheless force the user to continue attempting to merge all additional unresolved files. Future patches will allow the user to halt the merge process instead. This patch first introduces a test demonstrating the current bejhavior so the upcoming changes are more obvious.

dirstate: move the _dirfoldmap to dirstatemap Now that dirstatemap is the source of truth for the list of directories, let's move _dirfoldmap on to it. This pattern of moving cached variables onto the dirstate map makes it easier to invalidate them, as seen by how the cache invalidation functions are slowly shrinking to just be recreating the dirstatemap instance.

dirstate: remove _dirs property cache Now that dirs is source of truthed on the dirstatemap, let's get rid of the _dirs propertycache on the dirstate. Differential Revision: https://phab.mercurial-scm.org/D982

dirstate: remove _filefoldmap property cache Now that the filefoldmap is source of truthed on the dirstatemap, let's get rid of the property cache on the dirstate. Differential Revision: https://phab.mercurial-scm.org/D981

dirstate: move identity to dirstatemap Moving the identity function to the dirstatemap class will allow alternative dirstate implementations to replace the implementation. Differential Revision: https://phab.mercurial-scm.org/D980

dirstate: move nonnormal and otherparent sets to dirstatemap As part of separating dirstate business logic from storage, let's move the nonnormal and otherparent storage to the dirstatemap class. This will allow alternative dirstate storage to persist these sets instead of recomputing them. Differential Revision: https://phab.mercurial-scm.org/D979

dirstate: move write into dirstatemap As part of separating the dirstate business logic from the dirstate storage logic, let's move the serialization code down into dirstatemap. Differential Revision: https://phab.mercurial-scm.org/D978

dirstate: move _read into dirstatemap As part of separating the dirstate business logic from the storage, let's move the read code into the new dirstatemap class. Differential Revision: https://phab.mercurial-scm.org/D977

configitems: register the 'templates' section

configitems: register the 'paths' config section

configitems: register the 'pager.attend-.*' options

configitems: register the 'hooks' config section

configitems: register the 'extensions' section

configitems: register the 'defaults' section

configitems: register the 'committemplate' section

configitems: register the 'color' section

configitems: register the 'alias' section

configitems: allow for the registration of "generic" config item Some section can contains arbitrary keys (eg: color, alias, extensions). We add a way to register some generic config items for them. This is necessary to get all the config registered. We use a regular expression because some sub- attributes (eg: hooks.xxx.priority) can define default value on their own.

transaction-summary: show the range of new revisions upon pull/unbundle (BC) Upon pull or unbundle, we display a message with the range of new revisions fetched. This revision range could readily be used after a pull to look out what's new with 'hg log'. The algorithm takes care of filtering "obsolete" revisions that might be present in transaction's "changes" but should not be displayed to the end user.

i18n: cache translated messages per encoding This is a simpler workaround alternative to D958, "i18n: clean msgcache when encoding changes." The cache won't be bloated unless you run tons of commands with different --encoding options on command server, or serve many repositories of different web.encoding options on hgweb. The test was originally written by Jun Wu. Differential Revision: https://phab.mercurial-scm.org/D1053

templater: fix ifcontains() to handle type mismatch gracefully This was unintentionally changed in ee0d74083a22. Since ifcontains() takes needle of any types, it shouldn't abort depending on the given container type.

help: use single quotes in ``template example`` It was hard to read because ``""`` was rendered as """".

help: hide template keywords of obsolescence as they are still experimental

help: fix formatting of template keywords Our minirst formatter can't render multi-paragraph definition lists well. Also added periods where appropriate.

chg: remove outdated rule to start test server This rule is no longer useful because chg daemon may be killed and respawned per config/environment hash. We can't reliably run a daemon in foreground.

configitems: drop redundant default of web.allow<archtype> Otherwise develwarn would be sent to stderr. I've added blackbox logging to capture warnings.
