obsolete: add a devel.user.obsmarker In tests, we often want to use a different username in obs-markers without changing the default user. Add a 'devel.user.obsmarker'.

strip: factor out update target selection The same algorithm was used in two places: one to find out which commit shall become the parent of wdir, and the other to prepare the wdir when keeping changes. Factoring it out prevents inconsistent changes in either occurrence.

tests: optimize test-copytrace-heuristics.t test-copytrace-heuristics.t tests the heuristics algorithm of copytracing. The test has a pattern of making a server repo first and then cloning into a local repo for each test to have public and draft commits. This is done because if we have all draft commits and we have very less commits, heuristics will fallback to full copytracing as that will be fast. To avoid creating the server repo, we set the commit limit to -1 so that everytime we perform the heuristics algorithm even when having full drafts and tweak the config setting when we need to test the ability to fallback to full copytracing. This optimizes this test by 3 seconds. Before: real 0m41.503s user 0m36.068s sys 0m3.900s After: real 0m38.826s user 0m33.884s sys 0m3.396s Differential Revision: https://phab.mercurial-scm.org/D991

patch: do not cache translated messages (API) Previously the code caches `i18n._` results in module variables. That causes issues after an encoding change. Instead of invalidating them manually, we now just recalculate the translated messages every time `filterpatch` gets called. This makes test-commit-interactive.t pass regardless of whether chg or demandimport is used or not. .. api: `patch.messages` now lives in `patch.getmessages()`. Extensions adding new messages should now wrap the `patch.getmessages` method instead of changing `patch.messages` directly. Differential Revision: https://phab.mercurial-scm.org/D959

fsmonitor: add new watchman notifications to fsmonitor extension The fsmonitor extension currently sends state-enter and state-leave notifications to watchman on the update operation. This commit creates additional notifications for the following events : - transaction creation and commit/abort. A state-enter notification will be sent when a transaction is created. It will provide the working copy parent's hash. A state-leave notification will be sent when the transaction is committed or aborted. It will provide the working copy parent's hash. - calls to set-parent will cause state-enter and state-leave notifications to be sent. The state-enter notification will be sent prior to the set-parent operation and the working copy parent's hash will be provided at this time. The state-leave notification will be sent after the set-parent operation completes providing the working copy parents hash. Test Plan: tested on dev server to check that necessary notifications were sent/received Differential Revision: https://phab.mercurial-scm.org/D989

fsmonitor: change the distance calculation Change the distance calculation in the fsmonitor extension. It is done in a method since anticipated changes will need to use this logic as well. Test Plan: Tested on development server. Differential Revision: https://phab.mercurial-scm.org/D988

configitems: update default value of 'phases.new-commit' Now that mq is cleaned up, we can rely on the config register for the default value. We switch the default from the integer to human readable value to help with future automatic documentation that could be generated from the config register.

mq: use the newcommitphase utility We use the official API instead of doing the operation manually. This will help storing the default value for phases properly in the next changeset.

patch: rename "header" variable into "hdr" in diff() The "header" variable was hiding the eponymous class, hence preventing its usage.

merge: rename conflicts to fileconflicts in _checkunknownfiles We will need to distinguish between file conflicts and path conflicts. Rename the conflicts variable so that it will be clearly distinct from pathconflicts, which will be introduced in a future commit. Differential Revision: https://phab.mercurial-scm.org/D780

merge: backup conflicting directories when getting files During batchget, if a target file conflicts with a directory, or if the directory a target file is in conflicts with a file, backup and remove the conflicting file or directory before performing the get. Differential Revision: https://phab.mercurial-scm.org/D778

merge: add merge action 'pr' to rename files during update Add a new merge action to handle a path conflict by renaming the conflicting file to a safe name. The rename is just to avoid problems on the filesystem. The conflict is still considered unresolved until the user marks the original path as resolved. Differential Revision: https://phab.mercurial-scm.org/D777

scmutil: handle conflicting files and dirs in origbackuppath When ui.origbackuppath is set, .orig files are stored outside of the working copy. However conflicts can occur when files or directories end up having the same name. These conflicts cause Mercurial to abort, even if they've been created as a result of different backups. Make sure we always replace files or directories in the origbackuppath if they conflict with another file or directory. Test Plan: Add new unit test for conflicting paths. Differential Revision: https://phab.mercurial-scm.org/D680

extdata: show debug message if external command exits with non-zero status This isn't fatal because it's quite common for grep to exit with 1. Thanks to Foozy for spotting this.

templatekw: allow accessing to nested namespace item by its template name Since we have the dot operator, it makes more sense to write {namespaces.tags % "{tag}"} instead of {namespaces.tags % "{name}"}

templatekw: get rid of temporary dicts from shownamespaces()

templatekw: rename peerpaths to peerurls per naming convention (BC) Since each element is called as "url", the template keyword should be named as "<whatever>urls". {peerurls} is now stabilized.

templatekw: make experimental {peerpaths} return a single-level dict (BC) This was planned as in c0d8de2724ce, "{peerpaths.default.pushurl} will be translated to peerpaths['default'].makemap()['pushurl'], which means {peerpaths} should be a single-level dict and sub-options should be makemap()-ed."

templatekw: fix scope of peerpath url bound to generator I had to explicitly bind 'd' to the generator. Otherwise, the last 'd' would be used.

templater: extend dot operator as a short for get(dict, key)

templater: add dot operator to easily access a sub item This and the next patch will allow us to access a deeply-nested item by foo.bar.baz syntax.

templater: wrap get/min/max result so map operation can apply to element See the test for usage example. wraphybridvalue() takes a key/value pair because a hybrid dict passes a key to its makemap() function. Since makemap() of showmanifest() doesn't need a key, it's set to None.

dispatch: move initialization of sys.std* files I'll add another Python 3 hack.

chg: just forward --time to command server Since we've removed the use of atexit in de5c9d0e02ea, --time just works.

windows: add an experimental option for long paths support This commit adds an experimental --long-paths-support flag to build_hgexe on Windows. It is off by default, but when supplied, causes setup.py to embed some XML into the generated hg.exe, which in turn tells Windows to allow this exe to use long paths (given that the appropriate registry setting is enabled as well). This was tested on Windows 10 14393 and 15063. This commit introduces a badly-named initialize_options function, but its name is dictated by distutils, rather than chosen. # no-check-commit
