 26 Jan 2009, Stefan Ritt, Info, Subrun scheme implemented
|
[quote="Renee Poutissou"]I have tested the new subrun functionality a bit more and I have two observations. First, it seems to work on a basic level, i.e.
subruns are created, which are equal in size. However, I can't relate their size to the byte limit set in the ODB.[/quote]

(catching up on recent changes from t2k and pienu)
Various timeout problems fixed:

07 May 2009, Konstantin Olchanski, Info, RPC.SHM gyration
|
When using remote midas clients with mserver, you may have noticed the zero-size .RPC.SHM files
these clients create in the directory where you run them. These files are associated with the semaphore
created by the midas rpc layer (rpc_call) to synchronize rpc calls between multiple threads. This

07 May 2009, Konstantin Olchanski, Info, mhttpd now uses mtransition
|
mhttpd function for starting and stopping runs now uses cm_transition(DETACH) which spawns an
external helper program called mtransition to handle the transition sequencing. This helps with the old
problem of looking at a blank screen for a long time if some frontends take a long time to process run

07 May 2009, Konstantin Olchanski, Info, SQL history documentation
|
Documentation for writing midas history data to SQL (mysql) is now documented in midas doxygen files
(make dox; firefox doxfiles/html/index.html). The corresponding logger and mhttpd code has been
committed for some time now and it is used in production environment by the t2k/nd280 slow controls

> - cm_transition() timeouts now settable from ODB (/experiment/transition timeout, transition connect timeout). Rev 4479
transition connect timeout was actually only half of that specified because of an error in computing timeout arguments to the select() system

> Right now, MIDAS does not have an abstraction for "local multi-thread mutex" (i.e. pthread_mutex & co) and mostly uses global semaphores
> for this task (with interesting coding results, i.e. for multithreaded locking of ODB). Perhaps such an abstraction should be introduced?

A new feature has been implemented in revision 4561 which allows runs with a
certain duration. To use this, one has to set the variaable

01 Dec 2009, Stefan Ritt, Info, Redesign of status page links

The custom and alias links in the standard midas status page were shown as HTML
links so far. If there are many links with names having spaces in their names,
it's a bit hard to distinguish between them. Therefore, they are packed now into
