b45cf7c743 The value to binary line in do_put was accidentally duplicated making extra work on a put. 2009-12-05 04:37:33 +08:00

25a78e0b8e Moved check_all_databases_closed inside check for G_DB_ENV != NULL, otherwise 
fails on LOCK_DATABASE when G_DATABASES_MUTEX is uninitialized.

37c84d760f Made test closer to what was happening in production. Sometimes fails with BDB Error: assert failure: ../dist/../mp/mp_fget.c/257: "bhp != NULL", also seen it run with CRC errors. 2009-06-23 15:16:59 -05:00

663e7f24ec Cleaned up the const != var tests to var != const. 2009-06-23 15:05:21 -05:00
Jon Meredith
0affeb825c Cleaned up driver 
- removed the lock checks now we are happy with the mutex
 - replaced 'const == var' tests with 'var == const' to make code consistent.

783acf09ba Relaced G_DATABASES rwlock with a mutex. 2009-06-23 15:02:33 -05:00
Jon Meredith
425d8ddf00 Added extra paranoia around G_DATABASES, checking it is valid at lock and unlock. 2009-06-23 15:02:33 -05:00
Jon Meredith
7c9da71b18 The read lock checks for the G_DATABASES rwlock were incorrect. Multiple readers 
are possible.  Now the check for exclusive port/thread is only done on writes.

Added an integration test that reproduces conditions seen during the local-storage-ops-
in-coord branch.

3d422bec1d Heavily instrumented rwlock code - rwlock seems to be misbehaving. 
About to replace with a mutex.wq

bfb1620fb8 Improved debug output on driver stop. 
Disabled active_dbs counter as coredump went away.
 2009-06-23 15:02:33 -05:00
Jon Meredith
2077413b9e Added active counts to dbref and portref to help see what is being corrupted 
in the coredump.
 2009-06-23 15:02:33 -05:00
Jon Meredith
86f39286b1 Added extra debug/paranoia on bdberl_drv_stop/bdberl_drv_finish while 
looking for the coredump on port close discovered on the local storage ops
inside coordinator branch.
 2009-06-23 15:02:33 -05:00
Jon Meredith
254e253d81 Added versions of transaction() and update() that take a transaction 
timeout.
 2009-06-23 15:02:33 -05:00

92b7c3a6ef Refactored environment variable checks. All go through common functions 
that validate conversion to unsigned int and prints an error message
on stderr if not used (would prefer to use SASL but it's as good as it
gets during driver setup).
 2009-06-23 15:02:33 -05:00

e295227147 Refactored common receive loops from many functions into recv_val() and recv_ok(). 2009-06-23 15:02:32 -05:00

Jon Meredith
1e3b89e24e Broke stats code out into bdberl_stats.h module. 
Had to rename some functions that became non-static.
Added some accessors to module static variables as needed.
 2009-06-23 15:02:32 -05:00
Jon Meredith
6fe6651757 Added more comprehensive debug output if built with debug=1. 
Made deadlock checker interval configurable.
 2009-06-23 15:02:32 -05:00
Jon Meredith
19addac0fe Made size of thread pools configurable from environment variables 
BDBERL_NUM_GENERAL_THREADS and BDBERL_NUM_TXN_THREADS.

497b9ca70f Forgot to remove a couple of unnecessary work_buffer copies. 2009-06-23 15:02:32 -05:00
Jon Meredith
56c1617f8e Converted truncate to use async_dbref. 2009-06-23 15:02:32 -05:00
Jon Meredith
def6d9376a Changed stats functions to use async_dbref/async_flags to pass parameters 
to async functions rather than work buffer.

512cec599e In cases where there was more than one pending request and no active requests, 
the linked list would be corrupted linking the pending request on the list of
active requests.

dc867e363b Incorporated Diz's crc generation/checking patch to bdberl.erl. 
Added crc checking before/after BDB accesses in C driver.
Changed get to use malloc DBTs rather than the user supplied buffer
previously.

30fba1c995 Added stop(). Closes #318. 2009-06-02 13:36:07 -06:00
Jon Meredith
30c7ad75ac Replaced calls to getenv with erl_drv_getenv/G_DB_ENV->get_home. The erlang 
docs say not to use getenv in erlang drivers as they are not thread safe.
The places we were using them were very unlikley to have issues, but you never
know.

a3462d0fa7 txn_abort() used to return ok even if no txn. The error code changes 
broke that behavior.  Changed it to return ok if there was no txn.
