You are right but my script does't update the same resource/document
simultaneously because each thread uploads new files under new unique names
on the server, in that each thread
*1) creates its own instance of the repository*
* # 2) upload files and update properties*
* # connect to the server *
* client = cmislib.CmisClient(SERVER_URL, USER, PASSWD)*
* # get default repository*
* repo = client.defaultRepository*
*2) retrieves the target folder's node id*
* # get the target folder to upload new documents into*
* results = repo.query("select * from cmis:folder where cmis:name = '%s'"%(
TARGET_ALFRESCO_FOLDER, ))*
* targetFolder = results[0]*
* targetFolder = repo.getObject( targetFolder.id )*
*3) for each file (eg. file_i ) in a loop python statement*
* newDoc = targetFolder.createDocument( file_i['docName'], contentFile =
inFile ) *
* props = {*
* u'cm:title': file_i[ HDR_TITLE ],*
* u'cm:description': file_i[ HDR_DESCR ],*
* }*
* newDoc.updateProperties(props)*
So what I am doing is that I access the same folder and upload new
documents using unique names. I am 100% sure the document names (ie.
* file_i['docName']*) are unique under the same folder.
It just doesn't seem to me to be any concurrency problem with above code.
Many thanks anyways,
M
