obsolete: invalidate "volatile" set cache after merging marker Adding markers to the repository might affect the set of obsolete changesets. So we most remove the "volatile" set who rely in that data. We add two missing invalidations after merging markers. This was caught by code change in the evolve extensions tests. This issues highlight that the current way to do things is a bit fragile, however we keep things simple for stable.

win32mbcs: wrap underlying pycompat.bytestr to use checkwinfilename safely win32mbcs wraps some functions, to prevent them from unintentionally treating backslash (0x5c), which is used as the second or later byte of multi bytes characters by problematic encodings, as a path component delimiter on Windows platform. This wrapping assumes that wrapped functions can safely accept unicode string arguments. Unfortunately, d1937bdcee8c broke this assumption by introducing pycompat.bytestr() into util.checkwinfilename() for py3 support. After that, wrapped checkwinfilename() always fails for non-ASCII filename at pycompat.bytestr() invocation. This patch wraps underlying pycompat.bytestr() function to use util.checkwinfilename() safely. To avoid similar regression in the future, another patch series will add smoke testing on default branch.

hghave: prefill more version of Mercurial The previous code was unable to go above version 4.0.

graft: fix graft across merges of duplicates of grafted changes Graft used findmissingrevs to find the candidates for graft duplicates in the destination. That function operates with the constraint: 1. N is an ancestor of some node in 'heads' 2. N is not an ancestor of any node in 'common' For our purpose, we do however have to work correctly in cases where the graft set has multiple roots or where merges between graft ranges are skipped. The only changesets we can be sure doesn't have ancestors that are grafts of any changeset in the graftset, are the ones that are common ancestors of *all* changesets in the graftset. We thus need: 2. N is not an ancestor of all nodes in 'common' This change will graft more correctly, but it will also in some cases make graft slower by making it search through a bigger and unnecessary large sets of changes to find duplicates. In the general case of grafting individual or linear sets, we do the same amount of work as before.

graft: test coverage of grafts and how merges can break duplicate detection This demonstrates unfortunate behaviour: extending the graft range cause the graft to behave differently. When the graft range includes a merge, we fail to detect duplicates that are ancestors of the merge.

churn: use the non-deprecated template option in the examples

sslutil: reference fingerprints config option properly (issue5559) The config option is "host:fingerprints" not "host.fingerprints". This warning message is bad and misleads users.

largefiles: make sure debugstate command is populated before wrapping Copied the hack from 869d660b8669, which seemed the simplest workaround. Perhaps debugcommands.py should have its own commands table.

help: describe about choice of :prompt as a fallback merge tool explicitly "merge-tools" help topic has described that the merge of the file fails if no tool is found to merge binary or symlink, since c77f6276c9e7 (or Mercurial 1.7), which based on (already removed) MergeProgram wiki page. But even at that revision, and of course now, merge of the file doesn't fail automatically for binary/symlink. ":prompt" (or equivalent logic) is used, if there is no appropriate tool configuration for binary/symlink.
