Prepare repo r1:
|
|
|
|
$ mkdir r1
|
|
$ cd r1
|
|
$ hg init
|
|
|
|
$ 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/fncache
|

1 r1/.hg/store/undo
|

|
Create hardlinked clone r2:
|
|
|
|
$ hg clone -U --debug r1 r2
|
|
linked 7 files
|
|
|
|
Create non-hardlinked clone r3:
|
|
|
|
$ hg clone --pull r1 r3
|
|

|
|
|
|
|
|
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/undo
|
|
|
|
$ 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/undo
|
|
|
|
|
|
Create a non-inlined filelog in r3:
|
|
|
|
$ cd r3/d1
|
|
$ python -c 'for x in range(10000): print x' >> data1
|
|
$ 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/undo
|
|
|
|
Push to repo r1 should break up most hardlinks in r2:

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
