acd_cli mount delayed file size update

[tcf909]

Hello,

I noticed that when copying data to a acd_cli fuse mount, it takes some time for the filesize to show up (seems like something is syncing in the background). This causing things like rclone copy/sync to fail -- as the "copy" actually completes, but the filesystem represents the new file as zero bytes so the tool things the copy was corrupt and attempts to remove the file and try again.

Is there a setting to adjust this / fix this?

acd_cli version: acd_cli 0.3.2, api 0.9.2

I'm running on an AWS cloud instance (r4.xlarge) in the US-EAST-1 data center ( 2ms or less to ACD gateway).

Hoping to get this resolve, any guidance would be much appreciated.

acdcli creates files in a two step process, a 0 byte create call followed by an overwrite call. Under normal operation, acdcli cp calls should block until completion. If your ls -al calls are coming from a different thread/terminal, that's the behavior they'd see.

#374 fixes this somewhat since it'll return the write back cache size if the file hasn't yet been uploaded to amazon.

The blocking definitely isn't happening. The command

cp file.test ./mount/ && ls -l 

Will show 0 for the file. The real problem is that any program that requires a validation of file size after a copy operation (rclone or rsync) fails and continuously retries.

Definitely doesn't feel like expected behavior.
