Bug #1681 suggests that restic should not be nice to user and should
refrain from creating a mountpoint if it does not exist. Nevertheless,
it currently opens the repository before checking for the mountpoint's
existence. In the case of large or remote repositories, this process
can be time-consuming, delaying the inevitable outcome.
/restic mount --repo=REMOTE --verbose /tmp/backup
repository 33f14e42 opened (version 2, compression level max)
[0:38] 100.00% 162 / 162 index files loaded
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory
real 0m39.534s
user 1m53.961s
sys 0m3.044s
In this scenario, 40 seconds could have been saved if the nonexistence
of the path had been verified beforehand.
This patch relocates the mountpoint check to the beginning of the
runMount function, preceding the opening of the repository.
/restic mount --repo=REMOTE --verbose /tmp/backup
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory
real 0m0.136s
user 0m0.018s
