patch.internalpatch: add a default value for prefix Rev 60c279ab7bd3 adding a parameter here. This breaks third-party extensions like crecord and also makes the issue fairly hard to fix on the extension's side if it wants to retain compatibility across Mercurial versions -- in old versions, the positional argument will be passed into the next unknown argument, which is 'files'. The patch also undoes a change to the record extension that is no longer necessary.

histedit: remove extra histedit constructor call In a previous commit we removed the extra histedit object instance being constructed in --continue and --abort. The new --edit-todo missed this fix though (which means the state object it produces doesn't have the locks on it). It's not breaking anything now, but let's go ahead and clean that up before we forget.

color: consolidate cut-and-paste code This fixes a mild case of cut-and-paste code regarding failing to set terminal modes. This is evident in the win32 comment that is misplaced for the terminfo mode since cset ad6ad51cc0dd. Instead, we refactor this C&P into a small local function.

cmdutil.tryimportone: allow importing relative patches with --bypass

cmdutil.tryimportone: allow importing relative patches into the working dir This makes hg import --prefix dir/ (without bypass) work.

commands.import: accept a prefix option The --prefix option is meant to be relative to the root rather than the current working directory. This is for consistency with the rest of 'hg import' -- paths in patches are otherwise considered to be relative to the root. In upcoming patches we'll hook this option up to the patch functions. --exact with --prefix is currently disallowed because I can't really come up with sensible semantics for it, especially when only part of the patch is preserved.

test: make version based test-extensions failure more explanatory A buggy __version__ content (usually from setup.py's hg being unable to read the repo) can make this test fails in an obscure manner. We make the root of the failure more explicit.

subrepo: add status support for ignored and clean files in git subrepos

revlog: addgroup checks if incoming deltas add censored revs, sets flag bit A censored revision stored in a revlog should have the censored revlog index flag bit set. This implies we must know if a revision is censored before we add it to the revlog. When adding revisions from exchanged deltas, we would prefer to determine this flag without decoding every single full text. This change introduces a heuristic based on assumptions around the Mercurial delta format and filelog metadata. Since deltas which produce a censored revision must be full-replacement deltas, we can read the delta's first bytes to check the filelog metadata. Since "censored" is the alphabetically first filelog metadata key, censored filelog revisions have a well-known prefix we can look for.
