record: refactor the filtering code

record: consolidate ui.write wrapping in a function

bookmarks: reuse @number bookmark, if it refers changeset referred remotely Before this patch, "@number" suffixed bookmark may be newly created at each "hg pull" from the remote repository, if the bookmark in remote repository diverges from one in local one. This causes unexpected increase of "@number" suffixed bookmarks. This patch reuses "@number" suffixed bookmark, if it refers the changeset which is referred by the same bookmark in the remote repository.

bookmarks: check @pathalias suffix before available @number for efficiency Before this patch, available "@number" suffix is searched before "@pathalias" suffix, even though the latter has higher priority than the former if the latter exits. This patch checks "@pathalias" suffix before available "@number" for efficiency. When an URL has multiple path definitions, the first one is used for "pathalias" after this patch, even though the last one is used before this patch, because: - this choice can terminate loop immediately for efficiency - such case seems to be rare

bookmarks: prevent divergent bookmark from being updated unexpectedly Before this patch, "@99" suffixed bookmark may be updated unexpectedly by the bookmark value on the remote side at "hg pull", if all of "@1" to "@99" suffixed bookmarks exist in the local repository, because variable "n" still refers "@99" suffixed bookmark after the loop to examine "@num" suffixes, even though it already exists in the local repository. This patch prevents divergent bookmark from being updated unexpectedly, and shows warning message in such situation. This patch uses original python script "seq.py" instead of "seq" command to create sequence numbers in the test, because "seq" command may not be available: it isn't defined in recent POSIX specification (POSIX.1-2001 2013 Edition or XPG7)

manifest: include Python.h before standard headers Python.h should be included before any standard headers according to the python docs: https://docs.python.org/2/c-api/intro.html#include-files

crecord: use colwidth instead of ucolwidth

manifest: speed up matches for large sets of files If the number of files being matched is large, the bisection overhead can dominate, which caused a performance regression for revert --all and histedit. This introduces a (fairly arbitrary) cross-over from using bisections to bulk search.

perf: add methods for timing changeset file list reading

censor: add exchange tests, via local push/pull and bundle/unbundle These tests exercise the edge cases of exchanging censored commits between censor-aware Mercurial clients. These tests do not extend to cover backwards-compatible exchange; such tests require a script which builds older versions of Mercurial. For more background on the censorship feature design, see: http://mercurial.selenic.com/wiki/CensorPlan

censor: add censor command to hgext with basic client-side tests The censor command is a core extension which can replace the contents of a historical file revision with a censor "tombstone" which can be exchanged with older clients in place of the real revision data. The command rewrites the filelog by copying revision-by-revision. Care must be taken to expand the fulltext of the children of the censored revision before copying them to the new filelog; they might be stored as deltas against the uncensored revision, and those deltas will be invalidated.

record: add comparison methods for recordhunk class

record: minor refactoring of dorecord It prepares the way for introducing the flag to reverse hunk selection

record: add tests for the curses recording interface

record: enable curses recording logic with experimental flag

record: change arguments of curses recording function This way the arguments are the same for both curses and non-curses versions.

record: change interface of the filtering function This way filtering functions accept chunks and return chunks

hgweb: replace 'ctx._repo' with 'ctx.repo()'

pvec: replace 'ctx._repo' with 'ctx.repo()'

scmutil: replace 'ctx._repo' with 'ctx.repo()'

templater: replace 'ctx._repo' with 'ctx.repo()'

largefiles: replace 'ctx._repo' with 'ctx.repo()'

obsolete: replace 'ctx._repo' with 'ctx.repo()'

fileset: replace 'ctx._repo' with 'ctx.repo()'

filectx: add a repo accessor This is similar to a07314472a80 in motivation. All contexts now have this method, so the rest of the 'ctx._repo' uses can be converted without worrying about what type of context it is.

run-tests: ignore ENOENT failures when removing old .err results When the same test runs in multiple threads and the previous run was a failure, the threads can race to delete the error output. This fixes that.

run-tests: stop storing start/stop times in a dict by test name This resolves the last breakage in run-tests that prevented me from running a single test many times in several threads in parallel. This will be useful for testing potential fixes to flaky tests.

run-tests: avoid running the same test instance concurrently There's a fair amount of mutable state stored on test case instances. That causes many weird failures if you try to do something like `run-tests.py -j16 --loop test-help.t`. The quick fix is this slightly weird test-reloading dance, which ensures that every time a test is executed it runs on a fresh instance of the TestCase subclass.

run-tests: add --runs-per-test flag This is useful when you're working with a flaky test and want to run it (for example) 500 times to see if it'll false-fail. This currently breaks if you use it with more than one thread, but I'm looking into that now.

convert: adjust progress bar for octopus merges (issue4169) For merges, we walk the files N-1 times, where N is the number of parents. This means that for an octopus merge with 3 parents and 2 changed files, we actually fetch 6 files. This corrects the progress output of the convert command when such commits are encountered.
