CmisInvalidArgumentException when downloading Private Working Copy from Alfresco via CMIS -

-

my open-source app downloads files of alfresco folder (by cmis).
algorithm simple:

  1. list content of folder folder.getchildren()
  2. download each document.getcontentstream()

it works fine, except folders contain working copy of file, in case alfresco says:

org.apache.chemistry.opencmis.commons.exceptions.cmisinvalidargumentexception: stream id invalid: workspace://spacesstore/8b9a58ba-652f-4a18-8d26-aba06df98d25;pwc     @ org.alfresco.opencmis.cmisconnector.getcontentstream(cmisconnector.java:1199)     @ org.alfresco.opencmis.alfrescocmisserviceimpl.getcontentstream(alfrescocmisserviceimpl.java:1795)     @ sun.reflect.generatedmethodaccessor700.invoke(unknown source)

the ;pwc means "private working copy", special case in cmis protocol. working copies created when alfresco share user clicks "edit offline" on document (aka check out/check in).

is algorithm flawed? or bug in alfresco/opencmis?

i'm not sure of details, don't paste here code triggers exception , don't mention chemistry version you're using. anyway, if run following groovy code within cmis workbench v0.8.0 print files contents:

def obj = session.getobjectbypath("/cc"); def children = obj.getchildren(); (doc in children) {   def s = doc.getcontentstream();   def = s.getstream();   println(i.text); }

the cc folder used above 1 created in alfresco cmis instance, put file , checked out create pwc. assume there issue code, above code uses same api.

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
