I changed the mhttpd odb inline editor to use the json-rpc interface. Good things:

16 May 2017, Konstantin Olchanski, Bug Report, problem with odb strings and db_get_record()
|
Suddenly the mhttpd odb inline editor is truncating the odb string entries to the actual length of the
stored string value, this causes db_get_record() explode with "structure mismatch" errors. (Not my
fault, You Honor! Honest!). For example, I see these errors from al_check() after changing

31 May 2017, Konstantin Olchanski, Info, modified db_watch() arguments
|
for reasons unknown, db_watch() did not have an "info" parameter passed through to the callback
handler function, like it is done with db_open_record().

The mess with db_get_record() and db_open_record() is even deeper than I thought. There are several anomalies.

Done to all in-tree programs, except for mana.c (not using it), sequencer.cxx (cannot test it) and a few places where watching a TID_INT.

The checks for byte sizes of critical data structures have been added to ensure (enforce) binary compatibility
of midas with itself on different platforms (32-bit and 64-bit intel, on PPC, on ARM, etc).

Quick reply.

11 Oct 2017, Konstantin Olchanski, Info, added support for ucLinux
|
Support for building for ucLinux was added to MIDAS. I use the emcraft toolchain and userland on
some kind of embedded ARM CPU that does not have an MMU. See the Makefile for details. The
main difference of ucLinux is lack of fork(), which cannot be done without an MMU. Not everything

13 Oct 2017, Konstantin Olchanski, Info, odb multithread support repaired
|
multithreaded access to odb was implemented back in 2013-2014. but recently a bug surfaced -
there was a race condition in the odb locking code against cm_watchdog(). Somehow this only
affected the mserver for the DRAGON experiment at TRIUMF. This is now fixed on the branch

I the agdaq system I see memory corruption in the mlogger. There were at least two bugs: one
memory allocation error in mxml and one incorrect memset() in mlogger.cxx. The mxml bug is fixed
in the mxml repository, mlogger.cxx bug is fixed in the midas-2017-10 branch.
