ITS#7377 Catch MDB user errors.
commit c0f3d9b9a8864e744a8d1eaffc99bc86026d5351 Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:15 2012 +0200
ITS#7377 Catch MDB setup errors and clean up.
commit fe1b3794de3944967bd4ebce46dd0dc0d3449a17 Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:15 2012 +0200
ITS#7364 Limit mdb lock upgrade before sem_unlink.
Do not try shared lock when closing or after error. Track file lock state to decide. Change meaning of *excl to reflect file lock state.
commit c760e536ec1b9fed01b4d8e8d884533dceec397d Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:15 2012 +0200
ITS#7364 Always sem_unlink() in mdb_env_open().
Drop the sem_unlink() error checks, which could prevent the 2nd unlink. Instead use O_EXCL in sem_open().
This makes "open+close the database" the API for trying to clean away the old semaphores, if they were left behind by a previous run.
commit 31be24896b455e45eaf4e3739299a19a29979183 Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:14 2012 +0200
ITS#7377 Wrap sem_wait & file locks in EINTR loops
commit a35f9b2a5346e84bc920111348a1ea7d1cdfe32a Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:14 2012 +0200
Remove mdb data races. Use (txnid_t)-1 as "no ID".
Avoid race between numreaders++ and reading numreaders at cleanup. Make the un-mutexed reset of reader table entry, atomic: Reset mr_pid only.
Instead check mr_pid != 0 in mdb_page_alloc()'s scan for readers. (txnid_t)-1 as "no ID"-mark avoids a check for mr_txnid != 0. The scan can stop when seeing an old reader.
commit 38cc1e96b48ef0d0f00b79543c4c6db879537546 Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:14 2012 +0200
Save pid in MDB_env instead of repeating getpid().
An open MDB environment does not survive or catch fork(), so repeating getpid() was pointless.
commit 20a216fcc9cbfad838f5bfc970a160a23e9fe2be Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:14 2012 +0200
MDB_WRITEMAP needs no DSYNC descriptor (me_mfd)
commit 588a84a5ae0eb9ea343802e24b199af835204bfd Author: Hallvard Furuseth hallvard@openldap.org Date: Mon Sep 17 15:42:14 2012 +0200
ITS#7363 Preprocessor namespace cleanup.
Rename USE_POSIX_SEM to MDB_USE_POSIX_SEM. Separate MDB_FDATASYNC from MDB_USE_POSIX_SEM.
