[Issue 9591] New: Solaris builds broken due to map file
by openldap-its＠openldap.org 27 Jul '21

27 Jul '21

https://bugs.openldap.org/show_bug.cgi?id=9591 Issue ID: 9591 Summary: Solaris builds broken due to map file Product: OpenLDAP Version: 2.5.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: build Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Solaris 11.4 fails to build because it uses a different option for the library symbol versioning map file. We need to detect this and provide the correct option (more at https://blogs.oracle.com/solaris/regex_and_glob_for_mapfiles-v2) -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=6138 --- Comment #9 from Howard Chu <hyc(a)openldap.org> --- (In reply to Hallvard Furuseth from comment #2) > back-ldap:extended.c also does "suppress response, it has been sent", > but does it by returning and setting rs->sr_err = SLAPD_ABANDON. Might > break assumptions somewhere that SLAPD_ABANDON implies o_abandon was > set. And I guess the hack fails if the operation gets cancelled. Now fixed to always let the frontend handle responses. But this is still awkward, and will need to be revisited again for ITS#9220. > ======================================================================== > > I think these are the Operation states related to Cancel and Abandon: > > op->o_abandon is set for these - could extend to multiple values: > A) Operation Abandoned/Cancelled by client. > B) Operation implicitly abandoned by client.

Help? syncprov has been changed to use the new SLAPD_ASYNCOP returncode so it no longer needs to muck with this. > Overlay retcode does something similar - sends a response and then sets > o_abandon. I can't see any reason why this is needed. It's been there since the initial commit but I'm removing it. Any return code != SLAP_CB_CONTINUE already prevents the frontend from sending its own response so there's no reason to set this here. > Cancel/Abandon can in any case fail by targeting the wrong operation > though: A connection can have multiple messages with the same IDs when > the response is sent and the client reuses the message ID, before the > old operation in slapd can clean up and finish. > > syncprov_op_abandon() identifies messages by (connid, msgid). Can > multiple messages with the same ID break that, or more importantly, > break what gets sent/written with syncrepl? Sounds like bad practice in clients, but should still be safe. The messages are queued in order, so only the first matching message will be abandoned. Presumably the first incoming abandon request can only refer to the first queued operation of that ID. > Anyway, the current code needs an o_abandon value which means "suppress > response". Or maybe "abandoned, except as far as future Abandon and > Cancel operations are concerned". Syncprov and Retcode need to handle > the various possible orderings of Cancel/Abandon vs Suppress, including > when they forward o_abandon from one operation to another. I haven't > looked too closely at that code either. Mooted by use of SLAPD_ASYNCOP returncode. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 8890] Adapt timet to 64-bit long
by openldap-its＠openldap.org 26 Jul '21

26 Jul '21

https://bugs.openldap.org/show_bug.cgi?id=8890 --- Comment #14 from tg(a)debian.org <tg(a)debian.org> --- The bug is mistitled. It should be “adapt to 64-bit time_t on systems with 32-bit long”, which has become a fairly standard setup in the last 15 years and will become even more so in the next… less than 17 years, I suppose. -- You are receiving this mail because: You are on the CC list for the issue.
