Vincent Tang commented on CMIS-871: ----------------------------------- Thank you Florian. I removed the changeLogToken from the changes link in RepositoryInfo. Now my tests passed. I think the only not answered question is #3. I cannot find a way in OpenCMIS API. Therefore I wrote a test case that directly sends HTTP requests. > Client API Atompub binding - getContentChanges still sends change log token > even though I specify null for the changeLogToken parameter > --------------------------------------------------------------------------------------------------------------------------------------- > > Key: CMIS-871 > URL: https://issues.apache.org/jira/browse/CMIS-871 > Project: Chemistry > Issue Type: Bug > Components: opencmis-client > Affects Versions: OpenCMIS 0.12.0 > Environment: Windows 64 bits > Reporter: Vincent Tang > Labels: getContentChanges > > I found 2 OpenCMIS Client API problems in my test to use OpenCMIS Client API > Session.getContentChanges(String changeLogToken, boolean includeProperties). > The test is calling it like session.getContentChanges(null, false); You see I > set null to changeLogToken. Based on my understanding of CMIS specification, > I assume that the API would not include a change log token in the request. > The problems I found are > 1. OpenCMIS API send a changeLogToken anyway in Atompub binding but null in > Web services binding. The latter is compliant with CMIS specification but the > former is not. I think the OpenCMIS API in Atompub binding has a bug. > 2. This API sends a default maxItems in request because our test doesn't > specify one. However OpenCMIS API sends an unreasonable maxItem 2147483647. I > think it is the maximum value of a java integer. It causes different effect > in Atompub and web services bindings. > In Atompub binding, because of the bug (a change log token is passed in), > CMIS passed the change log token and the maxItems in the query, the query > returns the change events after the change log token. Therefore the test > cases passed. > In web services binding, the null value change log token and the maxItems > will effectively return the entire change log from the repository. It causes > the query hang and eventually timed out after 300 seconds. > This JIRA is reporting the first problem. I am not sure if the second problem > (maxItems = 2147483647 by default) is a problem. Because CMIS specification > doesn't say anything about the default maxItems. We will do something at > server side to prevent such a unreasonable maxItems to be used in query. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
