histedit: check mutability of contexts correctly The right way to check if a context is mutable is to call .mutable(), not to compare .phase() with public.

manifest: mark addlistdelta and checkforbidden as module-private

convert: enable deterministic conversion progress bar for svn This produces slightly bad results when branches are in play, but overall I think it's probably worthwhile. We might be able to do better with branches somehow, but I haven't given it any thought.

convert: enable deterministic conversion progress bar for git

test-convert-git.t: add a test of convert progress bars for git We're about to enhance this support, so test the existing behavior so the improved behavior is obvious in the next patch.

convert: add support for deterministic progress bar on scanning phase This makes it possible to estimate how long the "scanning source" phase will take, if the specified source repo type supports a quick "how many changes" check.

test-convert-svn-move.t: remove stray '

manifest: move addlistdelta to module-level Again, there's no reason for this to be inside manifest.add, so we'll define it only once.

manifest: move checkforbidden to module-level There's no need for this function to be nested, so let's just define it once instead of every time manifest.add() gets called.

dirstate: add exception when calling setparent without begin/end (API) Adds an exception when calling dirstate.setparent without having first called dirstate.beginparentchange. This will prevent people from writing code that modifies the dirstate parent without considering the transactionality of their change. This will break third party extensions that call setparents.

dirstate: add test for exceptions during updates Adds a test that checks if the working copy parent and the working copy are in a good state if an exception happens between the time the working copy parent is set and the time the actual updates are recorded in the dirstate.

dirstate: wrap setparent calls with begin/endparentchange (issue4353) This wraps all the locations of dirstate.setparent with the appropriate begin/endparentchange calls. This will prevent exceptions during those calls from causing incoherent dirstates (issue4353).

dirstate: add begin/endparentchange to dirstate It's possible for the dirstate to become incoherent (issue4353) if there is an exception in the middle of the dirstate parent and entries being written (like if the user ctrl+c's). This change adds begin/endparentchange which a future patch will require to be set before changing the dirstate parent. This will allow us to prevent writing the dirstate in the event of an exception while changing the parent.

parsers: avoid signed/unsigned comparison mismatch Based on warning from Microsoft Visual C++ 2008.

parsers: use correct type for file offset Now using Py_ssize_t instead of long to denote offset in file whose length is already measured using Py_ssize_t. Length and offset are now consistent. Based on warning from Microsoft Visual C++ 2008.
