patch: stop changing current directory before patching _applydiff() patcher argument was added to help hgsubversion like extension monkeypatching the patching process. While it could be removed at this point, I prefer to leave it until patch.py is completely refactored and there is a valid and tested alternative.

revlog: linearize created changegroups in generaldelta revlogs This greatly improves the speed of the bundling process, and often reduces the bundle size considerably. (Although if the repository is already ordered, this has little effect on both time and bundle size.) For non-generaldelta clients, the reduced bundle size translates to a reduced repository size, similar to shrinking the revlogs (which uses the exact same algorithm). For generaldelta clients the difference is minor. When the new bundle format comes, reordering will not be necessary since we can then store the deltaparent relationsships directly. The eventual default behavior for clients and servers is presented in the table below, where "new" implies support for GD as well as the new bundle format: old client new client old server old bundle, no reorder old bundle, no reorder new server, non-GD old bundle, no reorder[1] old bundle, no reorder[2] new server, GD old bundle, reorder[3] new bundle, no reorder[4] [1] reordering is expensive on the server in this case, skip it [2] client can choose to do its own redelta here [3] reordering is needed because otherwise the pull does a lot of extra work on the server [4] reordering isn't needed because client can get deltabase in bundle format Currently, the default is to reorder on GD-servers, and not otherwise. A new setting, bundle.reorder, has been added to override the default reordering behavior. It can be set to either 'auto' (the default), or any true or false value as a standard boolean setting, to either force the reordering on or off regardless of generaldelta. Some timing data from a relatively branch test repository follows. All bundling is done with --all --type none options. Non-generaldelta, non-shrunk repo: ----------------------------------- Size: 276M Without reorder (default): Bundle time: 14.4 seconds Bundle size: 939M With reorder: Bundle time: 1 minute, 29.3 seconds Bundle size: 381M Generaldelta, non-shrunk repo: ----------------------------------- Size: 87M Without reorder: Bundle time: 2 minutes, 1.4 seconds Bundle size: 939M With reorder (default): Bundle time: 25.5 seconds Bundle size: 381M

revlogdag: add linearize function See the docstring for a detailed explanation. The linearizer was originally written by Benoit Boissinot.

localrepo, sshrepo: use Boolean create argument in __init__

commands: replace 'x = f(); return x' with 'return f()'

merge with stable

subrepo: respect non-default path for incoming/outgoing Push and pull set repo._subtoppath before pushing or pulling subrepos. The incoming and outgoing commands needed to do the same.

run-tests: print a newline after all warnings

annotate: fix alignment of columns in front of line numbers (issue2807)

revset: the name is optional for the tag predicate

revset: note case-sensitive match in grep

revset: note case-insensitive matches in keyword and user

revset: expand help for contains predicate

patch: remove unused variable to make pyflakes test happy

patch: add lexists() to backends, use it in selectfile() At this point, all applydiff() filesystem calls should pass through fsbackend.

patch: move copyfile() into backends, abstract basedir

patch: merge makerejlines() into write_rej()

patch: extract fs access from patchfile into fsbackend Most filesystem calls are already isolated in patchfile but this is not enough: renames are performed before patchfile is available and some chmod calls are even done outside of the applydiff call. Once all these calls are extracted into a backend class, we can provide cleaner APIs to write to a working directory context directly into the repository.

mq: fix qpush changes detection of renamed files patch.changedfile() was not considering renamed file source as changed.

httpconnection: correctly handle redirects from http to https Previously the connection cache for keepalives didn't keep track of ssl. This meant that when we connected to an https server after that same server via http, both on the default port, we'd incorrectly reuse the non-https connection as the default port meant the connection cache key was the same.

win32.py: add argtypes and restype This is a feature of ctypes. Without these, pypy complains with RuntimeWarning: C function without declared arguments called RuntimeWarning: C function without declared return type called As a side effect of specifying restypes, the return value of e.g. CreateFileA is now implicitly converted to an instance of _HANDLE, so we also need to change the definition _INVALID_HANDLE_VALUE = -1 to _INVALID_HANDLE_VALUE = _HANDLE(-1).value Otherwise, tests for equality to _INVALID_HANDLE_VALUE in code like def _getfileinfo(name): fh = _kernel32.CreateFileA(name, 0, _FILE_SHARE_READ | _FILE_SHARE_WRITE | _FILE_SHARE_DELETE, None, _OPEN_EXISTING, 0, None) if fh == _INVALID_HANDLE_VALUE: _raiseoserror(name) would now fail to detect an invalid handle, which in turn would lead to exceptions raised with wrong errno values, like e.g. >>> nlinks('missing.txt') Traceback (most recent call last): ... OSError: [Errno 9] missing.txt: The handle is invalid. instead of the correct (as per this patch and before it) >>> nlinks('missing.txt') Traceback (most recent call last): ... OSError: [Errno 2] missing.txt: The system cannot find the file specified.

win32.py: more explicit definition of _STD_ERROR_HANDLE

revset: add follow(filename) to follow a filename's history across copies
