[Issue 10229] New: ldap_result, when invoked with MSG_RECEIVED and a timeout value set to 0 (polling), does not return all available messages until it is called again

Issue ID: 10229 Summary: ldap_result, when invoked with MSG_RECEIVED and a timeout value set to 0 (polling), does not return all available messages until it is called again Product: OpenLDAP Version: 2.6.8 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs@openldap.org Reporter: nivanova@symas.com Target Milestone: ---
The issue is noticeable when ldap_result is used by the proxy back-ends. It has not affected back-meta behavior, because when a first call is unsuccessful, it retries with a small timeout. back-asyncmeta will also usually call it twice on the same connection from different threads, although this is not a desired behavior.

--- Comment #1 from Ondřej Kuzník ondra@mistotebe.net --- Does ITS#10060 (not in 2.6 though) relate to this in any way?

Does ITS#10060 (not in 2.6 though) relate to this in any way?
Doesn't seem so at the moment, it is in the same code, but this problem occurs when all=2 (MSG_RECEIVED) with a tv={0} (polling). Any other combination of these and things work as expected.

--- Comment #3 from Ondřej Kuzník ondra@mistotebe.net --- Could you describe the issue in more detail? i.e. what does it mean "unsuccessful" in your description, does it mean it will return an error? What error?

--- Comment #4 from Nadezhda Ivanova nivanova@symas.com --- Even though there is still at least one message in ld_responses, it sets errno to -5 (timeout), instead of returning this message in the *result pointer, as should be the case when called with MSG_RECEIVED.
