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.

subrepo: use subprocess.Popen without the shell As well as simplifying the code, this makes subprocess calls about 25% faster. Tested on a couple linux boxes. python -mtimeit -s'import subprocess' 'subprocess.Popen( "git version", shell=True, stdout=subprocess.PIPE).wait()' python -mtimeit -s'import subprocess' 'subprocess.Popen( ["git","version"], stdout=subprocess.PIPE).wait()'

subrepo: treat git error code 1 as success At least status, commit, merge-base, and diff all return 1 when not failing.

subrepo: gitsubrepo should inherit from abstractsubrepo

subrepo: initialize subrepo relative default paths relative to their root

bookmarks: create undo.bookmarks using repo.opener instead of util.copyfile This more closely matches how the other undo files are created, and we don't care about settings permissions or times on the file, which can fail if the user running hg doesn't own the file.

archival: don't set gzip filename header when there's no filename This mainly affects hgweb, which can generate tar.gz archives without filenames. Without this change, the header would be set to ".gz", which can confuse Safari into extracting the file and renaming it to "gz" when "Open 'safe' files after downloading" is enabled. file(1) before: hg-crew-5e51254ad4d4.tar.gz: gzip compressed data, was ".gz", last modified: Thu Dec 2 11:46:20 2010, max compression after: hg-crew-5e51254ad4d4.tar.gz: gzip compressed data, last modified: Thu Dec 2 11:46:20 2010, max compression

build: don't delete precious version information on 'make clean' setup.py rebuilds version information if it's locally available, regardless if file already exists.

patch: write .rej files without rewriting EOLs Do not pass reject file content to patchfile.writelines() to: - Avoid line endings transformations - Avoid polluting overriding implementations with unrelated data. They should override write_rej() to deal or ignore reject files properly. Bug report, analysis and original patch and test by Shun-ichi GOTO <shunichi.goto@gmail.com>

record: move copystat() hack out of util.copyfile() and into record b2410ed2cbe9 updated copyfile to also copy over atimes and mtimes. That behavior is specifically to trick editors into thinking files that hg record has modified haven't changed. We don't really care about preserving times in the general case.

util: make atomicfiles closable

subrepo: drop arguments unsupported by old git

subrepo: work around old git's remote naming scheme Older git versions use 'origin/master' Current git uses 'remotes/origin/master'

subrepo: use environment variable instead of git commit's --date Older git versions do not have a --date flag.

subrepo: parse git status's human-readable output Older git versions do not have a machine-readable output, but the default format has not changed over time.

subrepo: use subprocess's cwd instead of git's --work-tree Some older git commands (e.g. git merge) do not properly recognize the --work-tree argument, so abstract that away from git.

test-subrepo-git.t: make gitroot pushable earlier Older git versions get confused when the git repo becomes bare.

test-subrepo-git.t: silence git output Older git versions have different ideas of what output is considered quiet, so the tests can be more version-blind.

bdiff: Fix bogus NULL return

bdiff: dynamically allocate hunks Make the hunk list a singly-linked list rather than a large array.
