Re: [orion-dev] Another question about Server API / File API

Thanks for the correction John.
FWIW I just verified your semantics.

Hi Vitaly, 

I was the author of the server file implementation, and I missed your questions because I was away on holiday for the past two weeks. There are some incorrect details here. If you perform copy, move, or create with "no-overwrite" header, and there is a conflicting file at the destination, then the entire operation fails. You should get a 412 "precondition failed" response from the server. If you see a case where this does not happen, please open a bug. This is documented in the API here: 

http://wiki.eclipse.org/Orion/Server_API/File_API#Notes_on_POST_method 

These copy/move overwrite semantics were copied from WebDAV (apart from the header names): 

http://tools.ietf.org/html/rfc4918#section-9.9.3 

If you have any more questions feel free to ask and I will try to answer. If you see inconsistencies between spec and implementation, please open bug reports. 

John

Hi Simon, 
 
Ok. I understand your point. And probably the empty directories on the source side should be deleted (?). 
>From my perspective such “move, no-overwrite” produces a strange remains on the source side, bit if this is Orion specification, I can live with it. 
 
Thank you for the explanation.

Indeed. I should have clarified that case.
The move is a best effort so that all files that can be successfully moved are. If the files cannot be moved (because a file exists already and no-overwrite is set) they are "not deleted" and will remain in the source directory.

1) Perform a "copy, no-overwrite"
2) Delete the source folder and all sub-files and folders.

Hi Simon,

Thank you for the explanation.

Could you describe me in the same way “move, no-overwrite”?

Regards,
Vitaly

For copy with no-overwrite we will "try" to copy every file and folder only skipping files that already exist.
e.g.
1) If a folder already exists that's fine and any sub-file and folder copy operations will continue.
2) If a file already exists we will skip it.

Hi Mark,

Thank you for the explanation.

What should happen if by “copy directory, no-overwrite” one file inside of the destination directory already exists?
Should the whole command be canceled?
What if only the empty destination directory exists?

Regards,
Vitaly

Hi Vitaly,

Here are, taken from the Orion source code, the current values that can go into X-Create-Options. (This is not an exhaustive list: more options may be added in future, and implementations are required to ignore unrecognized options.)   
  • copy   
  • move   
  • no-overwrite
Valid combinations are produced by taking one of either "copy" or "move", and optionally adding "no-overwrite". Hence the valid combinations are:   
  • copy
  • move
  • copy,
    no-overwrite
    (order doesn't matter)       
  • move,no-overwrite  (order doesn't matter)
Thanks for pointing out that these details were missing from the Server API docs. I have added them to the wiki.

Mark

Hi all,

I have another question about Orion File API.

What are the possible values for  X-Create-Options ?
And what are the allowed combinations of this values ?

Is there some detailed documentation about it ?

Thanks in advance,
