An update would try to fetch any missing largefiles after having updated normal files and standins. That could fail or be interrupted and would leave the working directory in a state where the largefiles not only were missing but also were scheduled for remove ... and where the old largefile was left in place. Instead we now remove old largefiles before starting to download and update missing largefiles.

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
