MIDAS "programs" settings include: /programs/xxx/"auto start", "auto restart" and "auto stop". What do
they do?

22 Oct 2013, Konstantin Olchanski, Info, audit of db_get_record()
|
Record-oriented ODB functions db_create_record(), db_get_record(), db_check_record() and
db_set_record() require special attention to the consistency between their "C struct"s (usually defined in
midas.h), their initialization strings (usually defined in midas.h) and the contents of ODB.

Because of this problem, on MacOS, run transitions can get stuck forever - most timeouts do not work. (Specifically, recv_string() never times out)

In one of the experiments, we hit a long time bug in mdump - there was an array of 32 equipments and if
there were more than 32 entries under /equipment, it would overrun and corrupt memory. Somehow this
only showed up after mdump was switched to c++. The solution was to use std::vector instead of fixed

I added MIDAS Makefile rules for building ARM binaries: "make linuxarm" and "make cleanarm" will create

Yocto SDK ARM cross-compilers (GCC 4.7.x and 4.8.x respectively). (Makefile rules for building PPC

31 Jan 2014, Stefan Ritt, Info, Separation of MSCB subtree
|
Since several projects at PSI need MSCB but not MIDAS, I decided to separate the two repositories. So if you
need MIDAS with MSCB support inside mhttpd, you have to clone MIDAS, MXML and MSCB from bitbucket
(or the local clone at TRIUMF) as described in

As reported in the bug tracker, the proposed header does not work if no specific (= different from the default 60 sec.) update period is specified,
since then no cookie is present. Here is the updated code which works for all cases:

I am not sure what to do with the javascript snippet - I understand it should be somehow connected to /Custom/Header, but if I create the /Custom/Header
string, I cannot put this snippet
into this string using odbedit - if I try to cut&paste it into odbedit, it is truncated to the first line - nor using the mhttpd odb editor - when I cut&paste |
