Bliss / GFD.90

[andre-merzky]

This ticket is a collection of items which relate to the GFD.90 compliance of Bliss. At the moment, it contains the most obvious syntactic gaps - semantic gaps will be added over time.

• close() should be available for all stateful objects, or none (all I think).

  ASync:

• missing

  Monitorable:

• missing

  Attributes:

• attribute_is_removable() is missing
• find_attributes (pattern) is missing

  Context:

• constructor should get optional type
• a number of attributes are missing

  Session:

• the ctor should take a bool parameter to signal if a default session is created (which automatically picks up contexts from application environment

  URL:

• the URL class implementation is supposed to ensure that using setters will always result in a well formed URL - that is not the case in bliss.

  Object:

• clone method for deep copy is missing

  Exception:

• the exception should always contain the saga.Object instance which from which the exception originated. use case::

  try : 
    for file in files :
        file.copy ("file://localhost/tmp")
  except saga.Exception as e :
    # get_object will always yield a file in the above case
    print "copying file failed: " + e.get_object ().get_url ()

  job.State:

• Pending should be a substate of Running.

  job.Service:

• run_job() is missing
• the ctor needs to check the endpoint (exists, can be contacted)

  job.Job:

• I kind of understand the idea behind the ctor(url,id), but the service URL is part of the id - so it should be ctor(id).
  But also, why is that shortcut for job.Service(url).get_job(id) needed?
• job id should never change after being assigned.
• several methods, attribs, properties missing

  job.Container:

• this should become a task container eventually
• wait timeout should apply to the task container timeout, not the timeout on waits for the container's elements.
• container does not operate on IDs, but on instances -- get_job(id) does not make sense. It looks ok now, but will make no sense when the container becomes a task.Container.

  filesystem:

• this package actually implements the GFD.90 namespace package, and should be named thus. Or it should add read/write/seek methods.

  filesystem.Directory:

• ctor needs flags
• ctor should accept relative URLs (which are path relative to application's pwd)
• pattern in list() should be used.
• open/open_dir missing
• inspection methods missing
• get_url/get_cwd/is_file,dir,link and others missing
• links missing
• dir should have move(tgt) and move(src,tgt) etc.
• all src/tgt URLs should be either absolute, or relative to the dir's pwd
• move is missing
• many methods miss flags, in particular for overwrite on copy/move, and CreateParents for make_dir, but also others

  filesystem.File:

• most of the directory comments apply
• read/write/seek is missing

File.remove() is also missing.

All API-related issues will be addressed when we implement the proper Python language bindings after 1.0.
