test-serve: make the 'listening at *' lines optional
The daemonized serve process doesn't print these lines out (see 448d0c452140).
I was able to get it to with the following hack:
diff --git a/mercurial/win32.py b/mercurial/win32.py
--- a/mercurial/win32.py
+++ b/mercurial/win32.py

+
# No standard library function really spawns a fully detached
# process under win32 because they allocate pipes or other objects
# to handle standard streams communications. Passing these objects
However, MSYS translates --prefixes starting with '/' to 'C:/MinGW/msys/1.0',
which changes the output. The output isn't so important that I want to spend a
bunch of time on this, and risk breaking some subtle behavior of `hg serve -d`
with the more complicated code.

#require hardlink #require hardlink-whitelisted This test is similar to test-hardlinks.t, but will only run on some filesystems that we are sure to have known good hardlink supports (see issue4546 for an example where the filesystem claims hardlink support but is actually problematic). $ cat > nlinks.py <<EOF > import sys > from mercurial import util > for f in sorted(sys.stdin.readlines()): > f = f[:-1] > print util.nlinks(f), f > EOF $ nlinksdir() > { > find $1 -type f | python $TESTTMP/nlinks.py > } Some implementations of cp can't create hardlinks (replaces 'cp -al' on Linux): $ cat > linkcp.py <<EOF > from mercurial import util > import sys > util.copyfiles(sys.argv[1], sys.argv[2], hardlink=True) > EOF $ linkcp() > { > python $TESTTMP/linkcp.py $1 $2 > } Prepare repo r1: $ hg init r1 $ cd r1 $ echo c1 > f1 $ hg add f1 $ hg ci -m0 $ mkdir d1 $ cd d1 $ echo c2 > f2 $ hg add f2 $ hg ci -m1 $ cd ../.. $ nlinksdir r1/.hg/store 1 r1/.hg/store/00changelog.i 1 r1/.hg/store/00manifest.i 1 r1/.hg/store/data/d1/f2.i 1 r1/.hg/store/data/f1.i 1 r1/.hg/store/fncache 1 r1/.hg/store/phaseroots 1 r1/.hg/store/undo 1 r1/.hg/store/undo.backup.fncache 1 r1/.hg/store/undo.backupfiles 1 r1/.hg/store/undo.phaseroots Create hardlinked clone r2: $ hg clone -U --debug r1 r2 --config progress.debug=true linking: 1 linking: 2 linking: 3 linking: 4 linking: 5 linking: 6 linking: 7 linked 7 files Create non-hardlinked clone r3: $ hg clone --pull r1 r3 requesting all changes adding changesets adding manifests adding file changes added 2 changesets with 2 changes to 2 files updating to branch default 2 files updated, 0 files merged, 0 files removed, 0 files unresolved Repos r1 and r2 should now contain hardlinked files: $ nlinksdir r1/.hg/store 2 r1/.hg/store/00changelog.i 2 r1/.hg/store/00manifest.i 2 r1/.hg/store/data/d1/f2.i 2 r1/.hg/store/data/f1.i 2 r1/.hg/store/fncache 1 r1/.hg/store/phaseroots 1 r1/.hg/store/undo 1 r1/.hg/store/undo.backup.fncache 1 r1/.hg/store/undo.backupfiles 1 r1/.hg/store/undo.phaseroots $ nlinksdir r2/.hg/store 2 r2/.hg/store/00changelog.i 2 r2/.hg/store/00manifest.i 2 r2/.hg/store/data/d1/f2.i 2 r2/.hg/store/data/f1.i 2 r2/.hg/store/fncache Repo r3 should not be hardlinked: $ nlinksdir r3/.hg/store 1 r3/.hg/store/00changelog.i 1 r3/.hg/store/00manifest.i 1 r3/.hg/store/data/d1/f2.i 1 r3/.hg/store/data/f1.i 1 r3/.hg/store/fncache 1 r3/.hg/store/phaseroots 1 r3/.hg/store/undo 1 r3/.hg/store/undo.backupfiles 1 r3/.hg/store/undo.phaseroots Create a non-inlined filelog in r3: $ cd r3/d1 >>> f = open('data1', 'wb') >>> for x in range(10000): ... f.write("%s\n" % str(x)) >>> f.close() $ for j in 0 1 2 3 4 5 6 7 8 9; do > cat data1 >> f2 > hg commit -m$j > done $ cd ../.. $ nlinksdir r3/.hg/store 1 r3/.hg/store/00changelog.i 1 r3/.hg/store/00manifest.i 1 r3/.hg/store/data/d1/f2.d 1 r3/.hg/store/data/d1/f2.i 1 r3/.hg/store/data/f1.i 1 r3/.hg/store/fncache 1 r3/.hg/store/phaseroots 1 r3/.hg/store/undo 1 r3/.hg/store/undo.backup.fncache 1 r3/.hg/store/undo.backup.phaseroots 1 r3/.hg/store/undo.backupfiles 1 r3/.hg/store/undo.phaseroots Push to repo r1 should break up most hardlinks in r2: $ hg -R r2 verify checking changesets checking manifests crosschecking files in changesets and manifests checking files 2 files, 2 changesets, 2 total revisions $ cd r3 $ hg push pushing to $TESTTMP/r1 (glob) searching for changes adding changesets adding manifests adding file changes added 10 changesets with 10 changes to 1 files $ cd .. $ nlinksdir r2/.hg/store 1 r2/.hg/store/00changelog.i 1 r2/.hg/store/00manifest.i 1 r2/.hg/store/data/d1/f2.i 2 r2/.hg/store/data/f1.i 2 r2/.hg/store/fncache $ hg -R r2 verify checking changesets checking manifests crosschecking files in changesets and manifests checking files 2 files, 2 changesets, 2 total revisions $ cd r1 $ hg up 1 files updated, 0 files merged, 0 files removed, 0 files unresolved Committing a change to f1 in r1 must break up hardlink f1.i in r2: $ echo c1c1 >> f1 $ hg ci -m00 $ cd .. $ nlinksdir r2/.hg/store 1 r2/.hg/store/00changelog.i 1 r2/.hg/store/00manifest.i 1 r2/.hg/store/data/d1/f2.i 1 r2/.hg/store/data/f1.i 2 r2/.hg/store/fncache $ cd r3 $ hg tip --template '{rev}:{node|short}\n' 11:a6451b6bc41f $ echo bla > f1 $ hg ci -m1 $ cd ..
