Override updaterepo() instead of individual methods that may not be called for each subrepo. Add test. Based on patch from Matt Harbison. Changes the order of update-related messages (now largefiles comes before the global status).

$ hg init alice

The largefile is not created in .hg/largefiles:
|
|
|
|
$ ls .hg/largefiles
|
|
dirstate
|
|
|
|
The user cache is not even created:
|
|
|
|
>>> import os; os.path.exists("$HOME/.cache/largefiles/")
|
|
False
|
|
|
|
Make the commit with space on the device:
|
|
|
|
$ hg commit -m big
|
|
|
|
Now make a clone with a full disk, and make sure lfutil.link function
|
|
makes copies instead of hardlinks:
|
|
|
|
$ cd ..
|
|
$ hg --config extensions.criple=$TESTTMP/criple.py clone --pull alice bob
