summary: simplify handling of active bookmark

summary: test that current bookmark isn't shown This exposes the current behavior in a test. A later change will make summary show when the active bookmark has moved out from under us.

merge crew heads

merge with stable

outgoing: fix possible filtering crash in outgoing (issue3814) If there is no outgoiing changesets but we have filtered revision in outgoing.excluded We run into a filtering related crash. The excluded revision should not be there in the first place but discovery need cleanup in default, not stable.

test: display used python hash seed We keep using a random seed for each run, but we "compute" it ourself to be able to reproduce a failed test run.

parsedate: understand "now" as a shortcut for the current time

export: clobber files with -o (bc) (issue3652) This violated user expectation. Updated the code to clobber files, but preserve the behavior of appending multiple patches requested in a single export. Includes tests.

merge: don't call copies.mergecopies unless we need to This reduces the amount of time we spend calculating when doing a clean non-merge update. In a large repo, the time dropped from 10.1 seconds to 3.4.

merge: rename p1 to wctx in manifestmerge This is always a workingctx, and this name is more in line with other functions in this module.

largefiles: fix test and check code

histedit: always abort with same message when working dir is wrong. Using only one message makes live easier for translators. The clearer error message was supposed by Augie Fackler.

histedit: report when revisions to edit are not ancestors of working dir Editing the history only is possible when the working dir is a descendant of the revisions to edit. When this happens explain it by writing abort: %s is not an ancestor of working directory

Merge

manifestmerge: handle abort on local unknown, remote created files This replaces the _checkunknown call in calculateupdates with a more performant version. On a repository with over 150,000 files, this speeds up an update by 0.6-0.8 seconds, which is up to 25%. This does not introduce any UI changes. There is existing test coverage for every case, mostly in test-merge*.t.

manifestmerge: pass in branchmerge and force separately This will be used in an upcoming patch.

manifest: use a size 3 LRU cache to store parsed manifests Previously, the manifest cache would store the last manifest parsed. We could run into situations with operations like update where we would try parsing the manifest for a revision r1, then r2, then r1 again. This increases the cache size to 3 to avoid that bit of performance fragility.

util: add an LRU cache dict In certain cases we would like to have a cache of the last N results of a given computation, where N is small. This will be used in an upcoming patch to increase the size of the manifest cache from 1 to 3.

tests: remove last two check-code warnings about killdaemons Removes the last of the warnings in test-check-code-hg.t introduced in 667063b22a69.

tests: guard against obsolete markers in the hg repo itself If obsolete markers appear in the hg repo (because of enabling evolve), then tests that run hg against the hg repo itself will see warnings like: obsolete feature not enabled but 4 markers found! As far as I can tell, this only occurs in test-check-code-hg.t -- in particular, it will -not- show up on tests that run against test-created repos, as most of the test suite does.

largefiles: make caching largefiles message more explicit In some cases, caching largefiles may take a long time (if the user has pulled a lot of new heads). This patch makes it more clear what is happening, by showing the number of heads we are caching largefiles for.

largefiles: document behavior of caching largefiles for new heads

check-code: add Makefile target to run check-code

byterange: remove now-unused sys import
