commit: if relevant, tell user their commit message was saved. (issue1635) Specifically, if: 1) the user edited the message (it didn't come straight from -m) and 2) the commit was aborted by an exception then the saved commit message in .hg/last-message.txt could come in handy, so mention it with a ui.write(). This doesn't help users who manually rollback to amend a changeset: the fact that the message was saved to .hg/last-message.txt is invisible in that case.

commit: save commit message so it's not destroyed by rollback. (issue1635) Rationale: if a pretxncommit hook rejects this commit, the transaction is rolled back and the user's commit message is irrevocably lost. So save a copy in .hg/last-message.txt, just in case. Also handy if the user deliberately rolls back a commit in order to amend it.

inotify: create a common, OS-independent server entry point * rename server.py to linuxserver.py * create server.py: it will contain OS-independent logic for servers, and will import the right server depending on the OS * old server.server class is renamed to linuxserver.socketlistener

perf.perflog: add option to follow renames

findrenames: improve coding-style

findrenames: speedup exact match benchmarked on crew repo with: rm -rf * ; hg up -C ; for i in `find . -name "*.py"` ; do mv $i $i.new;done followed by: hg addremove -s 100 before: Time: real 28.890 secs (user 26.920+0.000 sys 1.450+0.000) after : Time: real 6.790 secs (user 5.310+0.000 sys 1.350+0.000)

findrenames: refactor the score computation

findrenames: first loop over the removed files, it's faster Getting the file from the working dir is less expensive than getting it from the repo history, hence the speedup. benchmarked on crew repo with: rm -rf * ; hg up -C ; for i in `find . -name "*.py"` ; do mv $i $i.new;done followed by: hg addremove -s 100 before: Time: real 68.760 secs (user 65.760+0.000 sys 2.490+0.000) after : Time: real 28.890 secs (user 26.920+0.000 sys 1.450+0.000)

hgweb: add support for extension-provided permission hooks This allows extensions to hook into permission checking, providing both authentication and authorization as needed. The existing authorization function has been changed to a hook, which is added by default.
