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'
