[FUSE] Golang-based fuse driver

Description

Background:

Python+llfuse was expedient and has done lots of good work for us, but it's not promising as a long term (fast+reliable+maintainable) solution.

Implementation:

collection-backed filesystem from #12483, plus more general arvados-backed filesystem ("by_id" directory, etc, same as the one exported via webdav) from #13111
present as fuse using a library like https://godoc.org/bazil.org/fuse or https://godoc.org/github.com/billziss-gh/cgofuse/fuse
package as a subcommand ("mount") of the source:cmd/arvados-client program

TBD:

Approach for handling websocket "update" events
Selectable mechanisms/options for syncing to server (fflush, fsync, close) (on a shell node, flush-on-close, flush-periodically, or flush-after-idle-time might be best; in crunch-run, flush-on-exit might be best)
Desired behavior when updates conflict (write error? clobber? create "oops,clobbered" file?)

Other current bugs/limitations:

Old keep block signatures don't get refreshed, so reading a collection that's been cached for too long returns an I/O error
Not command-line compatible with arv-mount
Logging is not great
No docs
No way to control overall cache size (currently collectionfs can use lots of RAM in certain non-sequential write scenarios; we need the ability to trade speed for space efficiency in memory-constrained environments)
No warnings given when cache is thrashing
No application level instrumentation (just optional Go pprof)
Special .arvados#collection file is incomplete (has manifest_text but not uuid, pdh)
No automatic flush on sigint/sigterm
No warning given when trying to exit but filesystem can't be unmounted yet (filehandle is open, or a process's cwd is in the mount)
Mac port has a race bug (see notes below)
Windows port is untested
Cross-compiling recipe for Mac/Windows ports is fragile
chmod is a no-op (chmod 0700 succeeds, but the file mode will still be 0755)

Updated by Abram Connelly about 6 years ago

Using the new arv mount functionality, I created a new keep mount via:

$ mkdir keepgo
$ arvados-client mount --experimental keepgo/ -d 2> arv-mount-experimental.log

Going into the keepgo/home and doing some ls commands intermittantly gives the following error message:

abram@lightning-dev1:~/keepgo/home$ ls
ls: reading directory '.': Input/output error
00-example-shell.cwl input
Saved at 2015-05-06 21:13:44 UTC by crunch@01b0dfdb2f15  
...

Where, when the error occurs, it gives a partial list of the directory.

I don't see anything of note in the log so I haven't provided it here.

The non-fuse-related code here has been extracted and used in #13111.

Fuse parts are rebased against #13111, now 12308-cgofuse @ c5633c850d664d2f78e0efccf9ec9734b4e32de5.

12308-cgofuse @ 9a4fcabed1adeff0044d419977d5136c5cb1db3e -- developer-run-tests: #1715

Adds a "mount" subcommand to arvados-client, with limitations noted in the issue description above.

Our currently supported platforms (linux/amd64) work fine with the usual build process; source:cmd/arvados-client/Makefile has a recipe for cross-compiling binaries for linux/macos/windows on i386/amd64 using their respective fuse/fuse-like libraries.

I have been testing a binary compiled for OSX, using osxfuse version 3.10.4 and OSX 10.14.6

The test consists on cloning arvados' repository from github.

My latest 'black box' tests from last week were done with the linux binary and the issues found on the Mac version didn't happened: running multiple concurrent git clone operations worked great, also writing through a simulated slow link didn't crash the client.

Will give the code another look.

Code review:

lib/mount/command.go
- Line 29: Typo on comment
- Line 60: Could that be simplified by using arvadosclient.MakeArvadosClient()?
lib/mount/fs.go
- Line 65: Why should lookupFH() lock the filesystem while just reading data? — NOTE: As I’m learning, concurrent reads AND writes are not possible on maps, but could we use RWMutex to allow concurrent reads?
- Line 255: Does this conditional make the return value to be “Not implemented” when the fh is a regular file or dir? A comment would help future readers.

#24

Updated by Tom Clegg about 4 years ago

Description updated (diff)

lib/mount/command.go

Line 29: Typo on comment

Fixed

Line 60: Could that be simplified by using arvadosclient.MakeArvadosClient()?

Not sure I follow. We could use MakeArvadosClient(), but we'd need to call NewClientFromEnv() anyway to get the client var, and once we have that, it seems cleaner to derive the ac/kc clients from it...

lib/mount/fs.go

Line 65: Why should lookupFH() lock the filesystem while just reading data? — NOTE: As I’m learning, concurrent reads AND writes are not possible on maps, but could we use RWMutex to allow concurrent reads?

Yes, good point -- reads probably outnumber writes, so RWMutex is probably better / less blocking. Changed.

Line 255: Does this conditional make the return value to be “Not implemented” when the fh is a regular file or dir? A comment would help future readers.

Added comments. It's ENOSYS when changing mode from file to dir, or vice versa.

Line 257: The else clause isn’t necessary. In which case the flow would reach this? Asking because if we’re not implementing this, returning 0 is telling the SO that the operation succeeded.

Added comments. This is the case where chmod is expected to succeed (it's only changing permission bits). It's a no-op because we don't save permission bits. We could return ENOSYS if the mode isn't 0755. I suspect that would make lots of things (like tar xzf) fail instead of doing the obvious thing, though. Perhaps we should have "strict/loose" modes? Meanwhile I've added this to the list of shortcomings.

Thanks for the clarifications and comments, they'll be helpful.
About arvadosclient.MakeArvadosClient() I missed that the client var was used elsewhere, sorry.

This LGTM, thanks!
