[Bug 9229] New: Make liblutil usable by libldap
by openldap-its＠openldap.org 07 Nov '23

https://bugs.openldap.org/show_bug.cgi?id=9229 Bug ID: 9229 Summary: Make liblutil usable by libldap Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: build Assignee: bugs(a)openldap.org Reporter: ryan(a)openldap.org Target Milestone: --- liblutil is a static library (non-PIC) and so cannot be linked into shared objects, however we have several use cases for reusing its code in libldap. Some options: - moving more code from liblutil to libldap - just merge the whole thing? - are there components that link liblutil but _not_ libldap? - build liblutil as PIC (take a minor performance hit when linked into programs?) - build liblutil twice (liblutil.a and liblutil_pic.a) - symlink liblutil sources into libldap build dir, like libldap_r does with libldap - both of these last options require checking whether executables can call the PIC symbols safely (if some symbols are used by both library and program code) Nice-to-have for 2.5, I'd say more likely for 2.6 at this point. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 9221] New: Move all replication consumer code into its own overlay

https://bugs.openldap.org/show_bug.cgi?id=9221 Bug ID: 9221 Summary: Move all replication consumer code into its own overlay Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- (In relation to a discussion about slapo-chain) <hyc> anyway, the nicer ting to fix would be in 2.5, push all of the repl consumer code into its own overlay <hyc> in that case, updateref would be processed wherever the overlay was configured <hyc> so no longer tied to the frontend <hyc> it would also make it more feasible to have multiple different consumer configs in a single DB, each with their own provider URL (and thus their own updateref) <hyc> I would think we can get rid of the update ref directive entirely, just point all writes to that consumer's provider. -- You are receiving this mail because: You are on the CC list for the bug.

[Issue 10127] New: Thread Safety in LMDB with MDB_NOTLS and Readonly Cursors
by openldap-its＠openldap.org 07 Nov '23

https://bugs.openldap.org/show_bug.cgi?id=10127 Issue ID: 10127 Summary: Thread Safety in LMDB with MDB_NOTLS and Readonly Cursors Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: xiaoya2wei(a)gmail.com Target Milestone: --- Greetings LMDB Community, I am delving into the thread-safety aspects of LMDB, specifically regarding the use of readonly cursors across multiple threads. With the MDB_NOTLS flag enabled, which disables thread-local storage, my understanding is that readonly transactions may be shared between threads, provided there is proper synchronization to prevent concurrent access. Building upon this, I seek clarity on the following: Can multiple threads safely access a single readonly cursor derived from such a synchronized readonly transaction when MDB_NOTLS is enabled? Upon reviewing the LMDB source code, I noticed that cursors are tied to transactions (see mdb.c#L1335). This suggests that if threads can synchronously share a transaction, they might also share a cursor associated with it for data retrieval. I recognize my analysis might be superficial, and I'm open to corrections. Your insights on this matter would be greatly appreciated to enhance my understanding of LMDB's concurrency mechanisms. Thank you in advance for your assistance! -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 8852] slapd memory use grows continuously with non-delta syncrepl and modifying groups
by openldap-its＠openldap.org 03 Nov '23

03 Nov '23

https://bugs.openldap.org/show_bug.cgi?id=8852 --- Comment #8 from Ondřej Kuzník <ondra(a)mistotebe.net> --- For comparison, using deltasync (and sortvals!) makes the consumer take a similar amount of CPU time (about +50-90 % on the provider's) to process the 10k value additions, just like Ryan noted earlier. On the other idea, no clue on whether we can somehow limit the amount of data queued up without severely impairing replication progress. -- You are receiving this mail because: You are on the CC list for the issue.
