commands.push: abort when revisions evaluate to empty set (BC) If the "-r" argument is specified to "hg push," the user has expressed an intent for a specific changeset to be present on the remote. If that expression cannot be mapped to a known changeset, the user's intent is ambiguous and cannot be acted upon without making assumptions. Previously, if arguments to `push -r <rev>` evaluated to an empty set (perhaps the user specified a revset that didn't evaluate to anything), the empty "revs" list would be passed down to "exchange.push" where it appears the empty list was being interpreted as "push everything." This patch adds validation to the "-r" argument to the push command. If the argument is specified but doesn't resolve to a changeset, the command will abort instead of doing something potentially unexpected. This patch is technically breaking backwards compatibility. I believe this is justified because the new behavior closes a crack that could result in undefined or under-defined behavior. Also, this patch doesn't drop client capabilities because if users really wanted to push all changesets, they can simply omit the "-r" argument from push completely.

largefiles: fix typo with s/__class/__class__/ Commit f78252429e0a (largefiles: don't create chain of __contains__ calls, 2015-03-11) introduced a typo with __class instead of __class__. Let's fix it. There are (obviously) no tests covering this code path, and I could not figure out a way to trigger it, so it remains untested. Spotted by Drew Gottlieb.

hgweb: pull line numbers out of main flow of source content Pulls the autogenerated line number boxes outside of the padding box of the main content of .sourcelines, allowing the first tab to be properly sized and the line numbers to be outside the main source's margin when text is wrapped.

crecord: don't abort on Windows when curses isn't available This is the hack portion of the previous patch, which can be backed out once we figure out how to deal with curses. Without this, the tests affected by the import problem mentioned in the previous patch fail in exactly the same way, but with the nicer 'module not available' error.

test-fileset: forget non-portable files to avoid failures on Windows The 3 deleted lines appeared on Windows, because the files were never created in the first place.

crecord: conditionalize the imports that are not available on Windows 'fcntl', 'termios' and 'wcurses' are not available on the default Windows python installation, and importing them caused widespread carnage in the test suite. There were 29 different changed test files (on top of unrelated errors), mostly in the form of an ImportError. The failures weren't related to actual crecord use, and followed the import chain: 'localrepo' -> 'subrepo' -> 'cmdutil' -> 'crecord' -> 'fcntl'

cmdutil: drop a duplicate import of crecord It looks like this crept in with 69538481ea9f.

annotate: add option to annotate working-directory files Working revision or node is displayed with "+" suffix in plain output, but null/None in machine-readable format.

committablefilectx: override linkrev() to point to the associated changectx This is necessary to annotate workingctx revision. basefilectx.linkrev() can't be used because committablefilectx has no filelog. committablefilectx looks for parents() from self._changectx. That means fctx is linked to self._changectx, so linkrev() can simply be aliased to rev().
