convert: fix svn crash when svn.ra.get_log calls back with orig_paths=None get_log started calling back with orig_paths=None on Fedora 20 with subversion-1.8.3. That broke test-convert-svn-source.t . There used to be some handling of that situation until e8f4e40f285a apparently broke it. This patch restores what seems to be the most obvious handling of the situation.

share: fix unshare calling wrong repo.__init__() method When running the unshare command, if there's other code that tries to use the repo after the command is finished, it'll end up with a ui object for repo.unfiltered(). This change fixes an erroneous call to repo.__init__() that could be on the repoview proxy class--now it's always done on the unfiltered repo.

statichttprepo.httprangeheader: implement readlines bookmarks.readcurrent() requires readlines() on file objects returned from repo.vfs. It isn't used right now but will be in upcoming patches.

statichttprepo: pass in True to splitlines, not 1 splitlines actually takes a boolean.

mq: don't add '* * *' separators when there is no commit message

bisect: avoid confusing use of variables with same names in nested local scopes

discovery: make note messages for new heads more readable

discovery: tweak error message for multiple branch heads

test-obsolete-checkheads.t: remove todo comment that was fixed in be0fcbb1c92f

convert: readability and test of rpairs function

tests: make doctest test runner less verbose

tests: python hash seed is only relevant after failures - otherwise keep quiet

scmutil.filecache: support watching over multiple files

scmutil: introduce a filecacheentry that can watch multiple paths

scmutil: rename filecacheentry to filecachesubentry Upcoming patches will allow the file cache to watch over multiple files, and call the decorated function again if any of the files change. The particular use case for this is the bookmark store, which needs to be invalidated if either .hg/bookmarks or .hg/bookmarks.current changes. (This doesn't currently happen, which is a bug. This bug will also be fixed in upcoming patches.)

scmutil.filecacheentry: make stat argument to constructor mandatory There's no real upside to making stat optional -- this constructor has just two callers.

test-filecache.py: add markers to the output for each event Previously it was possible that a different, incorrect set of events might print out 'creating' the same number of times.

test-filecache.py: make setbeforeget test clearer '0' and 'None' as outputs tripped me up. Make the distinction between values set externally and values computed by calling the decorated function clearer.

test-module-imports.t: new test to use the import cycle detector

import-checker: try a little harder to show fewer cycles This makes sure that all cycles begin with the lexicographically first module, so that we're less likely to show overlapping cycles in the final analysis.

import-checker: ignore nested imports

contrib: add an import checker This checks for cycles in the module graph and verifies that imports of stdlib modules are not on the same line as relative imports of mercurial modules.

makememctx: move from patch to context to break import cycle

cleanup: move stdlib imports to their own import statement There are a few warnings still produced by my import checker, but those are false positives produced by modules that share a name with stdlib modules.
