scmutil: split platform-specific bits into their own modules
This parallels what's done for the util module, which imports either
mercurial.posix or mercurial.windows as 'platform' and then slurps the
appropriate functions into its own namespace.
Create user cache directory
$ USERCACHE=`pwd`/cache; export USERCACHE
$ cat <<EOF >> ${HGRCPATH}
> [extensions]
> hgext.largefiles=
> [largefiles]
> usercache=${USERCACHE}
> EOF
$ mkdir -p ${USERCACHE}
Create source repo, and commit adding largefile.
$ hg init src
$ cd src
$ echo large > large
$ hg add --large large
$ hg commit -m 'add largefile'
$ cd ..
Discard all cached largefiles in USERCACHE
$ rm -rf ${USERCACHE}
Create mirror repo, and pull from source without largefile:
"pull" is used instead of "clone" for suppression of (1) updating to
tip (= cahcing largefile from source repo), and (2) recording source
repo as "default" path in .hg/hgrc.
$ hg init mirror
$ cd mirror
$ hg pull ../src
pulling from ../src
requesting all changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files
(run 'hg update' to get a working copy)
caching largefiles for 1 heads
0 largefiles cached
Update working directory to "tip", which requires largefile("large"),
but there is no cache file for it. So, hg must treat it as
"missing"(!) file.
$ hg update

#if unix-permissions
Portable way to print file permissions:
$ cat > ls-l.py <<EOF
> #!/usr/bin/env python
> import sys, os
> path = sys.argv[1]
> print '%03o' % (os.lstat(path).st_mode & 0777)
> EOF
$ chmod +x ls-l.py
Test that files in .hg/largefiles inherit mode from .hg/store, not
from file in working copy:
$ cd src
$ chmod 750 .hg/store
$ chmod 660 large
$ echo change >> large
$ hg commit -m change
$ ../ls-l.py .hg/largefiles/e151b474069de4ca6898f67ce2f2a7263adf8fea
640
Test permission of with files in .hg/largefiles created by update:
$ cd ../mirror
$ rm -r "$USERCACHE" .hg/largefiles # avoid links
$ chmod 750 .hg/store
$ hg pull ../src --update -q
$ ../ls-l.py .hg/largefiles/e151b474069de4ca6898f67ce2f2a7263adf8fea
640
Test permission of files created by push:
$ hg serve -R ../src -d -p $HGPORT --pid-file hg.pid \
> --config "web.allow_push=*" --config web.push_ssl=no
$ cat hg.pid >> $DAEMON_PIDS
$ echo change >> large
$ hg commit -m change
$ rm -r "$USERCACHE"
$ hg push -q http://localhost:$HGPORT/
$ ../ls-l.py ../src/.hg/largefiles/b734e14a0971e370408ab9bce8d56d8485e368a9
