File copying with name generation on the storage element

Added by Harezlak Daniel over 12 years ago

When using the standard lcg-cr command it is possible to supply only the target storage element (with the -d option) and a local file location. In this case a file name on the storage element will be generated. Is it possible to have a similar behavior by using the JSAGA's jsaga-cp.sh command or JSAGA'a API?

Hi Daniel,

JSAGA can not implement this middleware-specific behavior because it has to follow the middleware-independant SAGA specification. The SAGA specification says on page 221 : "if the target is a directory, the source entry is copied into that directory".

However, you can implement this behavior with the methods of the JSAGA API, by generating the appropriate target URL by yourself.

Regards,
Sylvain

Dear Sylvain,

Thank you very much for the response. I suspected what you have written. Now, when I have an official confirmation I will start to develop an in-house name generation mechanism.

Regards,

Daniel Harezlak

Yes Daniel, the glite client commands rely on information published by the BDII to generate the full SRM path: root path + VO specific path + glite-specific subdirectory named "generated/<date_of_the_day>/<generated_filename>".
It is the responsibility of your code to deal with that, as Sylvain stated before, this is too much middleware-specific to implement in JSAGA.
