repoview: extract hideable revision computation in a dedicated function This will help extensions to plug into the hidden mechanism.

largefiles: make update with backup files in .hglf slightly less broken Largefiles update would try to copy f to f.orig if there was a .hglf/f.orig . That is in many many ways very very wrong, but it also caused an abort if f didn't exist. Now it only tries to copy f if it exists.

tests: fix up test-highlight for breadcrumb changes

color: add template label function

templater: add no-op template function 'label'

posix: fix split() for the case where the path is at the root of the filesystem posixpath.split() strips '/' from the dirname *unless it is the root*. This patch reproduces this behavior in posix.split(). The old behavior causes a crash when creating a file at the root of the repo with localrepo.wfile() when the repo is at the root of the filesystem.

record: remove unused import

cvsps: fix indentation

hghave: introduce a test (unused) for cvs >= 1.12

discovery: drop the visibleheads function It has no users left. (Using filtering explicitly is easier.)

clfilter: remove the last usage of `visibleheads` We can just inline the filtering now that all server code uses changelog filtering directly.

discovery: drop the visiblebranchmap function

clfilter: drop extra filtering in wireprotocol The repository used by wireprotocol is already filtered. We no longer need to call special functions.

clfilter: filter "unserved" on all wireprotocol command calls This ensures that unserved changesets are not exposed through the wire protocol.

clfilter: drop extra filtering in localpeer The repository used by localpeer is already filtered. We no longer need to call a special function.
