FTP | 30mb | Keep Trying option was accepted around fifteen times

GoogleCodeExporter commented 8 years ago

The macfuse file system is not responding. you can eject this volume
immediately, but unsaved changes may be lost.

1. Any transfer to or from ftp file servers will show this error on my
machine. at least one time with smaller files and several times with bigger
files. e.g. i had this timeout message show up for about 15 times with a
transfer of 30mb.
2. Clicking Keep Trying and Don't warn again will continue the transfer,
but message will show up again. By clicking Force Eject the finder and the
macfusion may crash completely.
3. The transfers are ok and intact when finished.

OS10.4.9 with 1.1Beta2 and core 0.3.0

greetz!

Interesting. This is a MacFuse issue, I think, or something related to 
curlftpfs.
If you get a chance, please post to the MacFuse tracker and see if Amit can 
make some
sense of this. If not, I'll go to the curlftpfs developer with this.

<http://code.google.com/p/macfuse/issues/detail?id=192> 
the Don't Warn Again button is broken in MacFUSE 0.3.0. 

Norman: in your estimation, might the moments at which you 
Keep Trying
coincide with network lags or disruptions, or with 
FTP service lags or disruptions?

I am having the same issue using ftp and finder to transfer files, though I 
can't see
any reason why I should be having ftp service lags or disruptions.
Using macfuse core 0.4.0 and macfusion 1.2 beta 2

Force Eject is never desirable. 

If you do force, then nothing should crash. 

If Finder does crash, then please provide the crash log. 

If MacFusion does crash, then please provide the crash log. 

Crash logs are typically at 
~/Library/Logs/CrashReporter/

If any problem recurs:

1) add the following Extra Options (Advanced) to the affected FTP favourite: 

-o ftpfs_debug=3 -d -v

2) after a problem occurs, let us have the output from the MacFusion Log 
window, plus other details that 
may be relevant.

hello,

thanx for your help. i just installed the new versions of the core and the gui, 
but
it still does not work for me. while uploading a 30 mb file, the timout message
showed up once and did not reappear after choosing do not warn again. the 
progress
bar and the copied file size rushes to approximately 95 percent then hangs up. i
tried to check filesize in the ftp finder window, but after just clicking in it 
the
whole finder hangs and gives me beachball. after waiting 5 minutes i relaunched
finder and the uploaded file is complete and working after quick download from 
ftp
back to local disc. erasing the file works too. now i tried uploading 20mb 
divided
into six files at once and there ist no error message and the progress bar does 
not
seem to hang or rush or something else. uploading works without timeout message 
and
checking filesizes works too for me this time. parallel up-/downloads of smaller
files are working. all in all the performed actions seem to be quite laggy and
delayed. the log window does not have information about the crashes...
using the advanced options as proposed my finder unfortunately hangs
(beachball.......) after i want to see the contents of the ftp directory. :(
i am really looking forward to a working and final version of this beautiful 
tool
without any hangups! 
thanx!
cheers.

I rarely use FTP but whilst using SSH, I have often been very surprised 
(pleased) by what seems to be 
intelligent use of caches/memory. I guess, this is thanks to MacFUSE. 

A guess: might your 'rush to 95 percent' reflect the percentage that has been 
_cached locally_ -- but not yet 
_written_ to the remote destination?

That might be, an issue with Apple Finder. 

Is the Finder window in Icons, List or Columns view?

If in Columns view, is the preview column enabled? 

If the preview column is enabled, are previews disclosed (triangle pointing 
down) or hidden?

Do you mean that all actions, including the actions that work, are quite laggy 
and delayed?

MacFusion 1.2 Beta 2 did not present this debug information (sorry); 
MacFusion nightly 20070627 revision 279 should be better. 

Making a distinction between beach balls and crashes: 

* if an application crashes -- without you forcing the event -- 
details may be logged at 

  ~/Library/Logs/CrashReporter

* if an application stops responding (beach ball); if you force an application 
to quit whilst it is unresponsive, 
I think this is different from a crash.

Whilst MacFusion is running, it logs to 

  ~/Library/Logs/MacFusion.log

> ... using the advanced options as proposed my finder unfortunately

That is curious but as noted above, there may be issues with Apple Finder. 

All things considered, it will probably be most useful for the developers to 
consider debug information.

Graham

Due to a limitation of the FTP protocol, every upload is only done when the 
file is
closed. Every write is buffered in memory and on close the file is uploaded as a
whole to the server.

This means that very large uploads may consume all your memory. It also means 
that
the finder will hang while uploading the big file. The ftp filesystem can't 
stop the
upload to answer to other requests because most ftp servers don't support 
resume on
uploads.

Even though the ftp mount is unaccessible, I think that is bad behavior for 
finder to
deny you access to other parts of your system. But this out of my control.

i have 2 gigs of ram installed and i am working with very much larger files up 
to
700mb in photoshop without any problems. how can working with a 30mb file in
macfuse/macfusion affect my finder this much? and why do i seem the only one 
affected
by these issues. if this was a common problem why would make macfusion sense at 
all?
i can work with any other ftp transfer program without any problem. the 
advantage and
elegance of integration into finder is not worth the instability and laggyness.

Robson, please: 

Might you advise use of any of the options listed below? 

(Re <http://code.google.com/p/macfuse/> I'm aware that "MacFUSE has a 
completely different kernel-level implementation from Linux FUSE" so I 
don't rush to experiment with options.) 

    -o nolocalcaches       meta option equivalent to noreadahead,noubc,novncache

    -o noreadahead         disable I/O read-ahead behavior for this file system
    -o nosynconclose       disable sync-on-close behavior (enabled by default)

    -o noubc               disable the unified buffer cache for this file system
    -o novncache           disable the vnode name cache for this file system

    -o direct_io           use direct I/O
    -o kernel_cache        cache files in kernel
    -o [no]auto_cache      enable caching based on modification times

    -o entry_timeout=T     cache timeout for names (1.0s)
    -o negative_timeout=T  cache timeout for deleted names (0.0s)
    -o attr_timeout=T      cache timeout for attributes (1.0s)
    -o ac_attr_timeout=T   auto cache timeout for attributes (attr_timeout)

    -o max_write=N         set maximum size of write requests
    -o max_readahead=N     set maximum readahead
    -o async_read          perform reads asynchronously (default)
    -o sync_read           perform reads synchronously

Whilst Apple Finder is excellent in many respects, it is sometimes imperfect. 

Example: at <http://code.google.com/p/macfuse/issues/detail?id=203> and  
<rtsp://qtss.freeman-
centre.ac.uk/2007/06/02/MacFUSE-issue-203.mov>, an issue that I first noted 
whilst using MacFUSE. The 
developer quickly discovered that the same weirdness occurs with Apple's UFS, 
MS-DOS, SMB, and WebDAV 
(iDisk) -- nothing to do with MacFUSE or MacFusion. 

> and why do i seem the only one affected by these issues. if this was a
> common problem 

At this stage, let's not estimate whether your problem is unique or common. The 
most important thing is 
that the issue is reported (thanks) and investigated. 

> why would make macfusion sense at all? 

FTP (CurlFtpFS) is just one possible use of MacFusion; consider 
<http://code.google.com/p/macfusion/wiki/FileSystemsToImplement>. 

> i can work with any other ftp transfer program without any problem. 

Apple Finder is different from your other FTP transfer programs. 

> the advantage and elegance of integration into finder

As I understand it, neither MacFUSE or MacFusion is integrating into Finder. 

FTP and SSH plug-ins to MacFusion allow 
FTP and SSH file systems to be treated as volumes. 

Finder will work with file systems, will work with volumes, in 
Finder's own way. 

Some problems are _unique_. Here, for example: 
<http://code.google.com/p/macfuse/issues/detail?id=159#c28> a long, greatly 
puzzling issue that affects 
no-one other than me. It transpired that these particular SSH and FTP services 
are simply unreliable; the 
problems were not limited to MacFUSE, MacFusion or Finder. 

norman.freese: before we estimate whether your situation is unique or common, 
let's work a little more on 
the issue. 

Kind regards
Graham

whether or not macfuse/macfusion integrates technically into finder, working 
with ftp
servers as volumes is a very elegant procedure for my purposes and i think not 
only
for me. data exchange with macfusion could be (in my case) / is a really cool 
thing.
i will follow the development of this software closely and i will appreciate 
and have
appreciated your help and responsiveness very much.
