17 Oct 2008, Konstantin Olchanski, Info, mlogger async transitions, etc
|
As we were looking into problems with starting and stopping runs in one of our
daq systems, we found that the mlogger does something differently compared to
mhttpd and odbedit. Starting and stopping runs from mhttpd and odbedit works

A new set of functions was added to mscb.h to adjust mscb timeouts and retries to better match specific
applications:

23 Oct 2008, Konstantin Olchanski, Bug Report, Inconsistent handling of odb and evet buffer timeouts
|
In midas.c there are several places where client last activity time stamps are checked against the
watchdog timeout and the clients are declared dead if they fail to update their activity time stamps.
ODB time stamps and data buffer time stamps appear to be handled in a similar manner.

23 Oct 2008, Konstantin Olchanski, Bug Report, strange output from "odbedit cleanup"
|
When I run odbedit remotely (odbedit -h ladd09), the "cleanup" command unexpectedly produces the
output of the "sor" command (sure enough, there is a call to db_get_open_records() there), but when I run
it locally, I do not get this output (but db_get_open_records() is still called). Strange. K.O. |

23 Oct 2008, Konstantin Olchanski, Bug Report, bm_wait_for_free_space never sleeps inside the mserver
|
When mserver receives events from remote client, writes them into a data buffer and this data buffer
becomes 100% full, we see mserver go into 100% consumption.

27 Nov 2008, Konstantin Olchanski, Bug Fix, Fix ss_file_size() on 32-bit Linux
|
It turns out that on 32-bit Linux, ss_file_size() returns the wrong answer for
files bigger than 2 GB (4GB?). The Linux stat() system call returns an error
(which is ignored) and bogus file size data (returned to the caller).

|
27 Nov 2008, Konstantin Olchanski, Bug Report, lazylogger complains about zero-size files
|
I now have a better understanding of this: lazylogger uses ss_file_size() to find
out if a file exists or not. This function used to return 0 (probably) for
non-existant files (there was no check for error status from stat() system call,
