Fix hgit revtree bug with stop revision handling

Fix hg cat when the file cannot be found in the specified revision

Add support for cloning with hardlinks on windows. In order to use hardlinks, the win32file module is needed, and this is present in ActivePython. If it isn't present, or hardlinks are not supported on the underlying filesystem, a regular copy is used. When using hardlinks the biggest benefit is probably the saving in space, but cloning can be much quicker. For example cloning the Xen tree (non trivial) without an update goes from about 95s to 15s. Unix-like platforms should be unaffected, although should be more tolerant on filesystems that don't support hard links.

Fix bug with co -C across branches, update tests

Fix test-tag output for new abort message

Revert unrelated changes in previous commit

Fix abort message for clone

Revert some exception type changes in revlog

CONTRIBUTORS update

dirstate: two more stat -> lstat changes

Fix comment typo

Fix dangling symlink bug in dirstate walk code

Replace sequences of {ui.warn, return 1} with raise of util.Abort.

patchbomb: add TLS and SMTP AUTH support. Original patch from Lee Cantey <lcantey@gmail.com>.

Add --debugger global option With this option, hg will drop into the Python debugger on execution. Running 'continue' will execute normally, and the debugger will be reinvoked if an exception is raised.

Fix Windows status problem from new dirstate walk code

Update test-help for bundle/unbundle

Fix missing docstring for unbundle

clone: directory names take precedence over symbolic names If source matches both a directory name and a symbolic name to repo, the directory will be taken.

import: fix bug in mail-format detection

hgweb: fix scope for RepoError

Add preliminary support for the bundle and unbundle commands

Add missing import for hgwebdir

Cleanup of tabs and trailing spaces in documentation.

Add reporting instructions to unknown exception backtraces

Smarter handling of revlog key errors Use RevlogError for reporting exceptions Catch and report RevlogError exceptions at the command parser

Clean up hgweb imports Use demandloading Pull function-local imports up to demandload Scope hg and ui bits

Change grep -e to grep --all We want to reserve -e for future use and grep compatibility. I've changed every-match to all out of a general preference for shorter long option names where short options don't exist.

Fold import -m option into import -f

Revert silly TypeError change

Tighten up clone locking Add a lock on the destination, expand comment on source lock

Clean up local clone file list We now use an explicit list of files to copy during clone so that we don't copy anything we shouldn't.

Rewrite copytree as copyfiles This inverts the logic of copytree to allow copying single files at the top level.

Redo local clone hgrc fix We shouldn't copy hgrc on a local clone, nor localtags. Behavior should be identical to a remote clone.

Write out hgrc properly. Previously, we simply appended to the hgrc file, which meant that it ended up containing multiple "paths" sections. Now, we only modify "paths.default".

patchbomb: continue if we can't import readline.

Get test-commit to exit cleanly.

Commit date validation: more stringent checks, more useful error messages.

revlog: raise informative exception if file is missing.

Minor cleanups.

Created a class in util called chunkbuffer that buffers reads from an iterator over strings (aka chunks). Also added to util (for future use) is a generator function that iterates over a file n bytes at a time. Lastly, localrepo was changed to use this new chunkbuffer class when reading changegroups form the local repository.
