Added tag 2.4.1 for changeset 0c10cf819146

osutil: fix tab damage

Merge with crew

osutil: factor out creation and init of listdir_stat

dirstate: avoid use of zip on big lists In a clean working directory containing 170,000 tracked files, this improves performance of "hg --time diff" from 1.69 seconds to 1.43. This idea is due to Siddharth Agarwal.

dirstate: move file type filtering to its source This prepares us to move to a much faster statfiles implementation on Unix.

clfilter: rename `unfilteredmeth` to `unfilteredmethod` As originally intended.

clfilter: fix a false positive in the test-obsolete.t We push between two repo which once filtered looks unrelated. Weakness in the current implementation allows this push to be done without -f. But later improvement with filtering will make this push fails for unrelatedness. However we want this push to fail for including bumped changeset. So we had a smaller push --force to make them related.

clfilter: ensure that filecache on localrepo is unfiltered All filecache usage on repo is for logic that should be unfiltered. The caches should be common to all filtered instances, and computation must be done unfiltered. A dedicated storecache subclass is created for this purpose.

clfilter: add a propertycache that must be unfiltered Some of the localrepo property caches must be computed unfiltered and stored globally. Some others must see the filtered version and store data relative to the current filtering. This changeset introduces two classes `unfilteredpropertycache` and `filteredpropertycache` for this purpose. A new function `hasunfilteredcache` is introduced for unambiguous checking for cached values on unfiltered repos. A few tweaks are made to the property cache class to allow overriding the way the computed value is stored on the object. Some logic relative to _tagcaches is cleaned up in the process.

largefile: status is buggy on repoproxy, so run unfiltered For some yet-unkown reason, largefile status does not work on repoproxy. As status is not affected by filtering, we run it unfiltered. Na'Tosha Bard's view on this issue: "but, well, largefiles status is kind of an unholy piece of code"

clfilter: mq should not warn about filtered mq patches MQ warns when qstatus contains unknown nodes. With changelog filtering, a node may be unknown because it is filtered. Thus, an unfiltered repo is used for this check.

clfilter: ensure that mq performs commits on unfiltered repos

clfilter: use unfiltered repo for bookmark push logic The remote location of the bookmark may be filtered locally. This changeset ensures that bookmark movement logic has access to all the repo's content.

clfilter: `bookmark.validdest` should run on unfiltered repo The logic recently added to `bookmark.validdest` uses data about obsolete changesets to see if a bookmark destination is valid. Obsolete changesets are likely to be filtered, so we need to work on an unfiltered repository.

clfilter: unfilter some parts of the push logic Computation of common changesets during push needs to be done on the widest set possible. An unfiltered version of the repo is kept for discovery and various revset calls. The discovery code itself enforces the filtering of unserved outgoing changeset.

subrepo: add argument to "diff()" to pass "ui" of caller side (issue3712) (API) Color extension achieves colorization by overriding the class of "ui" object just before command execution. Before this patch, "diff()" of abstractsubrepo and classes derived from it has no "ui" argument, so "diff()" of hgsubrepo uses "self._repo.ui" to invoke "cmdutil.diffordiffstat()". For separation of configuration between repositories, revision 573bec4ab7ba changed the initialization source of "self._repo.ui" from "ui"(overridden) to "baseui"(plain) of parent repository. And this caused break of colorization. This patch adds "ui" argument to "diff()" of abstractsubrepo and classes derived from it to pass "ui" object of caller side.

clfilter: prevent unwanted warning about filtered parents as unknown During changectx __init__ the dirstate's parents MAY be checked. If the repo is filtered, this check will complain "working directory has unknown parents" even if the parents are perfectly known. This may happen when the repo is used for serving and the dirstate has parents that are secret, as those secret changesets will be filtered.

clfilter: strip logic should be unfiltered Strip is a "write" operation that needs to be aware of the whole repo's content before destroying changesets. Only the low level function is altered. The top level command will still process its argument filtered (if any filtering is in place).

clfilter: verify logic should be unfiltered To verify a changelog obviously needs all of it. The verify logic now ensures it works on an unfiltered repository.

clfilter: phases logic should be unfiltered Phase computations and boundary movements need to be aware of all revisions that exist in the repository to return correct results.

clfilter: unfilter computation of obsolescence related computation All obsolescence related sets need to be computed on the full unfiltered version of the repository, in particular because several of them (obsolete, extinct) are used to compute the hidden revisions. On a filtered repo, revset predicates related to these sets will be properly filtered because of revset's own pre-filtering.

clfilter: ensure changeset creation in the repo is run unfiltered This applies to both creation of new commits and application of changegroups.

clfilter: ensure changegroup generation is run unfiltered Changegroup generation logic needs to be aware of the whole repository to work properly.

clfilter: ensure `rollback` is run unfiltered Rollback logic needs to be aware of the whole repository to work properly.

clfilter: ensure cache invalidation is done on the main unfiltered repo The proxy version will not hold any cache for now. But we have to ensure all cache operations are done on the unfiltered version.

clfilter: ensure that tag logic runs unfiltered The current tag logic is not aware of filtering. We keep the status quo, ensuring that the tag cache is computed as before: without any filtering.

clfilter: ensure `branchcache` logic runs unfiltered The current branchcache construction is not aware of filtering. We keep the status quo, ensuring that the branch cache logic is computed as before: without any filtering.

clfilter: introduce an `unfilteredmethod` decorator This decorator ensure the method in run on an unfiltered version of the repository. See follow-up commit for details. This decorator is not named `unfiltered` because it would clash with the `unfilteredmethod` on `localrepo` itself.

clfilter: introduce an "unfiltered" method on localrepo This commit is part of the changelog level filtering effort. It returns the main "unfiltered" version of a repo-like object. For localrepo this means the same localrepo object. But this method will be overwritten by the filtered versions of a repository to return the core unfiltered version of the repo. Introducing this simple method first allows later commits to prepare for the use of a filtered version of a repository. A new repo method is added because a lot of users may call it. At the end of this series of commits, about 40 calls exist in core and hgext.
