python3: move from using func_name to __name__ Previously reviewed as D964, but required some fixups and therefore seems to need a new revision. Differential Revision: https://phab.mercurial-scm.org/D1065

tests: add globs for Windows

test-conflicts: conditionalize for no-symlink platforms It seems better to create standin files for the symlinks, rather than blacklist the entire tests. Especially since link vs file doesn't seem to affect the tests. There is more instability in test-pathconflicts-{basic,merge}.t that I can't figure out.

test-extdata: conditonalize error message for Windows

test-audit-path: fill in missing output for no-symlink case It looks like this was meant to go with 989e884d1be9.

test-i18n: guard gettext test appropriately

hook: add a 'hashook' function to test for hook existence Preparing the data for some hooks can be expensive. Add a function to check if a hook exists so we can skip useless preparation if no hook is configured.

build: for the bootstrap phase of a deb/rpm build pure-py mercurial is enough When bootstrapping a deb/rpm build, packagelib.sh starts performing a local build for the sole purpose of parsing the output of "hg version". Then it "hg archive"s the source code, and builds everything again. For that initial step, we are perfectly good in using a pure python mercurial, without compiling the c modules (base85, bdiff, zstdlib, ...). On my personal system, this cuts down 22 seconds for a package build (the bootstrapping build goes from ~30 to ~8 seconds).

context: add a fast-comparision for arbitraryfilectx and workingfilectx Differential Revision: https://phab.mercurial-scm.org/D1056

tersestatus: avoid modifying tersedict Turn dirnode's methods into generators which can be used to update "tersedict" in caller. So instead of passing the "tersedict" to be mutated here and there, it's now clearer where it is updated as it's purely a local variable to tersedir() function. While I was here, I renamed _processtersestatus to tersewalk and _addfilestotersed to iterfilepaths. Differential Revision: https://phab.mercurial-scm.org/D1043

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. Differential Revision: https://phab.mercurial-scm.org/D930

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. Differential Revision: https://phab.mercurial-scm.org/D983

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
