Some implementations of cp can't create hardlinks (replaces 'cp -al' on Linux):
|
|
|
|
|
|
$ cat > linkcp.py <<EOF
|
|
|
> from mercurial import util
|
|
|

|
|

|
|
|
> 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
|
|

Create hardlinked clone r2:
|
|
|
|
|
|
$ hg clone -U --debug r1 r2 --config progress.debug=true
|
|
|
linking: 1
|
|

|
|
|
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 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
|
|

|
|

|
|
|
|
|
|

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 ../..

Committing a change to f1 in r1 must break up hardlink f1.i in r2:
|
|
|
|
|
|
$ echo c1c1 >> f1
|
|
|
$ hg ci -m00
|

$ echo bla > f1
|

$ hg ci -m1

Create hardlinked copy r4 of r3 (on Linux, we would call 'cp -al'):
|
|
|
|
|
|
$ linkcp r3 r4
|
|
|
|
|
|
r4 has hardlinks in the working dir (not just inside .hg):
