outgoing: respect ":pushurl" paths (issue5365) Make 'hg outgoing' respect "paths.default:pushurl" in addition to "paths.default-push". 'hg outgoing' has always meant "what will happen if I run 'hg push'?" and it's still documented that way: Show changesets not found in the specified destination repository or the default push location. These are the changesets that would be pushed if a push was requested. If the user uses the now-deprecated "paths.default-push" path, it continues to work that way. However, as described at https://bz.mercurial-scm.org/show_bug.cgi?id=5365, it doesn't behave the same with "paths.default:pushurl". Why does it matter? Similar to the bugzilla reporter, I have a read-only mirror of a non-Mercurial repository: upstream -> imported mirror -> user clone ^-----------------------/ Users push directly to upstream, and that content is then imported into the mirror. However, those repositories are not the same; it's possible that the mirroring has either broken completely, or an import process is running and not yet complete. In those cases, 'hg outgoing' will list changesets that have already been pushed. Mozilla's desired behavior described in bug 5365 can be accomplished through other means (e.g. 'hg outgoing default'), preserving the consistency and meaning of 'hg outgoing'.

tests: test-pathconflicts-merge.t requires symlinks Once we're ready to turn this functionality on more widely, we might want to write a symlink-free version of the test that can run on Windows, but for now we'll just leave it disabled there.

sshpeer: allow for additional environment passing to ssh exe We already have the ability to customize the ssh command line arguments, let's add the ability to customize its environment as well. Example use-case is ssh.exe from Git on Windows. If `HOME` enviroment variable is present and has some non-empty value, ssh.exe will try to access that location for some stuff (for example, it seems for resolving `~` in `.ssh/config`). Git for Windows seems to sometimess set this variable to the value of `/home/username` which probably works under Git Bash, but does not work in a native `cmd.exe` or `powershell`. Whatever the root cause, setting `HOME` to be an empty string heals things. Therefore, some distributors might want to set `sshenv.HOME=` in the configuration (seems less intrusive that forcing everyone to tweak their env).

unamend: allow unamending if allowunstable is set I don't see why unamend should be disallowed when allowunstable is set. By switching to rewriteutil.precheck() we fix that and get more consistent error messages (and some additional ones). Differential Revision: https://phab.mercurial-scm.org/D1682

lfs: using workers in lfs prefetch This significantly speeds up lfs prefetch. With fast network we are seeing ~50% improvement of overall prefetch times Because of worker's API in posix we do lose finegrained progress update and only see progress when a file finished downloading. Test Plan: Run tests: ./run-tests.py -l test-lfs* .... # Ran 4 tests, 0 skipped, 0 failed. Run commands resulting in lfs prefetch e.g. hg sparse --enable-profile Differential Revision: https://phab.mercurial-scm.org/D1568

worker: make windows workers daemons The windows workers weren't daemons and were not correctly killed when ctrl-c'd from the terminal. Withi this change when the main thread is killed, all daemons get killed as well. I also reduced the time we give to workers to cleanup nicely to not have people ctrl-c'ing when they get inpatient. The output when threads clened up nicely: PS C:\<dir>> hg.exe sparse --disable-profile SparseProfiles/<profile>.sparse interrupted! The output when threads don't clenup in 1 sec: PS C:\<dir> hg.exe sparse --enable-profile SparseProfiles/<profile>.sparse failed to kill worker threads while handling an exception interrupted! Exception in thread Thread-4 (most likely raised during interpreter shutdown): PS C:\<dir>> Test Plan: Run hg command on windows (pull/update/sparse). Ctrl-C'd sparse --enable-profile command that was using threads and observed in proces explorer that all threads got killed. ran tests on CentOS Differential Revision: https://phab.mercurial-scm.org/D1564

workers: add config to enable/diable workers This adds config to disable/enable workers with default being enabled. Test Plan: enabled profile without updaing .hg/hgrc (the default should be to use workers) and ran hg sprase --enable-profile <profile>.sparse Watched in the proces explorer that hg started 12 new threads for materializing files (this is my worker.numcpus) value Added [worker] enabled = False to the .hg/hgrc and re ran the command. This time hg didn't spawn any new threads for matreializing of files Differential Revision: https://phab.mercurial-scm.org/D1460

diff: disable diff.noprefix option for diffstat (issue5759) We could use patch.diffhunks() instead of patch.diff() to get filenames without parsing patch content, but that isn't always possible because we sometimes feed raw patch data to patch.diffstat().
