graphlog: fix log -G option types when translating to revset For instance, --keyword is a multiple value option while it was processed as a single value option.

revset: add tests for multiple and mixed ^ and ~ operators

extensions: obsolete and remove parentrevspec extension As of 305c97670d7a, revsets implements the ^ and ~ operators that this extension provides, so it's no longer necessary.

wix: a new mercurial.js has replaced graph.js

util.url: copy urllib.unquote() into util to improve startup times The ui class uses util.hasscheme() in a couple of places, causing hg to import urllib even when it doesn't need to. This copies urllib.unquote() to avoid that import. perfstartup time before the URL refactoring (8796fb6af67e): ! wall 0.050692 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) before this change: ! wall 0.064742 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) after this change: ! wall 0.052126 comb 0.000000 user 0.000000 sys 0.000000 (best of 100

url: move URL parsing functions into util to improve startup time The introduction of the new URL parsing code has created a startup time regression. This is mainly due to the use of url.hasscheme() in the ui class. It ends up importing many libraries that the url module requires. This fix helps marginally, but if we can get rid of the urllib import in the URL parser all together, startup time will go back to normal. perfstartup time before the URL refactoring (8796fb6af67e): ! wall 0.050692 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) current startup time (139fb11210bb): ! wall 0.070685 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) after this change: ! wall 0.064667 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)

revlog: introduce _chunkbase to allow filelog to override Used by revlog.revision to retrieve the base-chunk in a delta chain.

filelog: extract metadata parsing and packing _parsemeta returns the dictionary and a list of keys in the order they appear in metadata. This can be used to repack the dictionary in the same order. _packmeta creates metadata from a dictionary and an optional key-order list. In _parsemeta, we use slices and re.search indead of str.index so we can accept both buffers and strings.

discovery: drop findoutgoing and simplify findcommonincoming's api This is a long desired cleanup and paves the way for new discovery. To specify subsets for bundling changes, all code should use the heads of the desired subset ("heads") and the heads of the common subset ("common") to be excluded from the bundled set. These can be used revlog.findmissing instead of revlog.nodesbetween. This fixes an actual bug exposed by the change in test-bundle-r.t where we try to bundle a changeset while specifying that said changeset is to be assumed already present in the target. This used to still bundle the changeset. It no longer does. This is similar to the bugs fixed by the recent switch to heads/common for incoming/pull.

revset: add missing whitespace
