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.

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).

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.

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

56c1617f8e Converted truncate to use async_dbref. 2009-06-23 15:02:32 -05:00

def6d9376a Changed stats functions to use async_dbref/async_flags to pass parameters 
to async functions rather than work buffer.

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.

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.

1409096860 Renamed get_lg_dir() to get_lg_dir_info and added get_data_dirs_info(). 
Both new calls return the filesystem id and the number of mbytes available
on that filesystem.

Added debug messages on util thread error.

Jon Meredith
09081f000b Changed the utility thread sleep function to use a custom sleep based on pipe/select 
so they can be terminated quickly when the driver shuts down.

d833ca708c Changed bdberl_tpool_run to set a pointer to the job structure 
rather than return it.  There was an issue where the async thread cleanup
code finished before bdberl_tpool_run returned and wrote the address
of a freed TPoolJob structure into the ErlDrvPort.
