Feature Request: Compatability with other S3FS clients

[GoogleCodeExporter]

s3fs currently displays directories created in S3Fox as something like
"MyStuff_$folder$".  But, it shows up as an unknown file type, and not even
a directory.  Being able to understand those "folders" from S3Fox would be
a handy feature, IMO

Seconded.  So far in my S3 testing jungledisk(in compatibility mode) and s3fox 
use
the same directory structures and can read each other's buckets without a 
problem.

s3fs seems to use a different directory structure that is not compatible with 
either.

in my bucket there are 5 folders at the root - 

LS produces 1 of the folders with _$folder$ attached to the end of it

I can not CD into the folder. 

In other buckets I see more of the files, but the folders all have the 
_$folder$ and
seem to be impossible to open

Yes, this is very important to us. We have many people adding files using s3Fox 
and a
java server running on EC2 which cannot recognize the files.

I second this. This seems to be the only functional S3 filesystem, which can 
interact
with JungleDisk or S3 Organizer - except for the folders.

It would be great if you include this!

Hi, I agree with the other people, this is a very important feature, can put 
this in
High priority? regards, from Argentina

Count my vote too, definitely want to see a compatibility mode which will use 
the same node implementation as other common tools. Buckets I've populated with 
s3sync.rb are unreadable by s3fs which is unfortunate.

I have created a patch for s3fs to recognize and use s3fox organizer style 
folders. This has an overhead for getattr calls as it does two calls for 
getting attributes for a file(used extensively by fuse). So expect degradation 
for directories with large files. So use with caution. This is incompatible 
with the main branch.

Use at own risk. I am yet to use it for an extended period.

for me is the same. if i create a folder with aws console management, this 
folder and all inside not is present into s3fs mount point.
and if i create folder manually the same folder inside the mount point, it 
create first a zero byte file with the name of folder.
only when i create a file inside this folder. I reach to view all files 
(created by s3fs mount point and created by aws console)

Don't hold your breath, this isn't something that will be addressed anytime 
soon by the current set of developers.

3 years and no support. We're deprecating s3fs as a usable technology in our 
company for this very reason but the lack of compatibility with other tools is 
not there. S3Fox still shows folders created via the AWS Management Console 
and, while annoying, AWS MC still reads S3Fox-created folders - even if they 
display the empty 0-byte file in addition but the fact that this tools cannot 
recognize the folders at all is unfortunate. I would love to see this if 
there's an update - seems like a minor enhancement but then again, none of us 
have done it either. I think I'll just sync with S3 using a cron job and the 
Amazon S3 API tools instead.

Check out the s3fs fork that is compatible with AWS management Console, s3cmd 
and other S3 tools at https://github.com/tongwang/s3fs-c

This is a pretty big issue for a lot of people. Not being able to use the s3 
mgmt console really sucks.

Please see Issue 73, which claims s3fs version 1.64 has been updated to be 
compatible with other S3 clients.

Hi,

nicholas, Thanks.

But s3fs after v1.64 does not support s3fox yet, these clients make "_$folder$" 
suffix object.
I know that this issue is big issue, I try to support.

Regrads,

Hi, all

I updated codes as r413 which is fixed for "_$folder$" directory object.
You can see detail about 
r413(http://code.google.com/p/s3fs/source/detail?r=413).
Please try and check it.

New version v1.68 supports other S3 client's objects(dir).

I closed this issue.
If you find a same issue, please let me know.

I read this in the build notes,

"    After changing the object attributes, the object name does not have
"_$folder$" suffix.
    It means the object is remade by s3fs.
"

The *ONLY* client to aws-s3 that uses this convention is s3fs. It's a dead 
convention. I wouldn't want anything to revert to this format. The AWS 
management console was the last nail in the coffin on this. It went from "no 
spec" on how to do this functionality, to "spec by implementation", bucking the 
trend isn't an option and any "reverting" to a different format should be in 
itself a bug.

Hi,

Please let me confirm this issue.

New s3fs supports "_$folder$" object and the object(dir) which does not exist 
and has files and sub-directries.
1) New s3fs can read and recognize these directories.
    Is this function the problem?

2) When user changes file(dir) attributes(owner, group, permission, time), new 
s3fs changes the object type("_$folder$" or no-existed object) which s3fs 
usually makes.
    Does your opinion mean that s3fs chould not change object?

I think case-1 is not problem, because s3fs does not change the object(and 
type).
The case-2 changes the object and it's type(name).
Both "_$folder$" object and no-existed object do not have their file attribute 
which is defined HTTP headers(like "x-amz-meta-***").
But user want to set attributes to the object, then s3fs change(add)s the HTTP 
header.
On this case-2, the problems are classified in two kinds.
case 2-1) no-existed object
  s3fs must make new object, then s3fs makes the directory object which is usually used by s3fs.
case 2-2) "_$folder$" object
  This case was seductive.
  But I think there is no problem that the object is changed "_$folder$" type to normal type.
  (ex. "dir_$folder$" object is changed to "dir" object)
  Because user touchs the dir(object) throw s3fs(and fuse) and other S3 clients  can recognize normal type.

As noted above , I judged the new version changes the object(dir) of a special 
case.

Please le me know your thought.
Thanks in advance.
