hook: assume relative path to hook is given from repo root

subrepo: backed out changeset 2245fcd0e160

bundle progress: offer best-guess deterministic progress information This uses the same strategy as progress for pulls, estimating manifests based on changeset count and estimating file count by files list in each changeset.

httpsendfile: record progress information during read() This allows us to provide deterministic progress information during transfer of bundle data over HTTP. This is required because we currently buffer the bundle data to local disk prior to transfer since wsgiref lacks chunked transfer-coding support.

templatekw.showdiffstat: use ctx.diff() instead of calling patch

localrepo: remove unneeded os.unlink call in wwrite The opener already unlinks the filename before 'w'riting, for both the symlink and the normal file case. It also now resets the flags for normal files on 'w'rite, which makes this os.unlink call completely redundant. For Windows, removing this extra unlink call helps to avoid tripping issue2524 (os.unlink followed by a write).

opener: always reset flags on 'w'rite only the patcher needs to preserve flags on write

subrepo: silence git output when ui.quiet is set

subrepo: show git command with --debug Also removing the clutter of --no-pager, since none of these commands use the pager.

subrepo: speed up git push logic In many common cases where the subrepo is up to date with the remote repo, hg push will only need to run one git-branch command to see that nothing needs to be pushed.
