11 years ago Problem solved after git pull.
Below is Jude's message.
The problem was that the file creation was being delayed due to the write TTL of the parent directory not being 0 (it's 5000 by default). Not only was this not being handled properly (i.e. the CREATE message was never sent to the MS), but also creating files asynchronously with the MS will not be supported (at least, not until there's a compelling use-case for it).
Hi.
I met a bug while creating a new file in sub directory. I could replay the same problem with the syndicatefs (UG).
I used local MS, so probably this might be only replayable with local MS. After create a directory, just create a new file with "touch" command of linux. This causes infinite loop in uploader thread of ms client.
I don't know why it couldn't succeed uploading.
syndicatefs console shows below
...

And, GAE console shows below

"master" in this message is directory and "abc.ttt" is file I created.
However, creating sub directory in another directory works.
Here's my command.
iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ mkdir master iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls master iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls -al total 5 drwxrwxrwx 1 games tty 0 Jul 11 22:14 . drwxr-xr-x 3 root root 4096 Jun 4 13:32 .. drwxrwxr-x 1 games tty 4096 Jul 11 22:14 master iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ touch abc.txt iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls abc.txt master iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ cd master/ iychoi@iychoi-virtual-machine:/mnt/syndicatefs/master$ ls iychoi@iychoi-virtual-machine:/mnt/syndicatefs/master$ touch abc.ttt touch: closing `abc.ttt': No such file or directory iychoi@iychoi-virtual-machine:/mnt/syndicatefs/master$ ls abc.ttt iychoi@iychoi-virtual-machine:/mnt/syndicatefs/master$
Thank you for your time.
