Dear Midas users,
I have moved midas from CVS to Subversion today. There were many reasons for doing so, which I don't want to explain in detail here. To use the new repository, |

Hi,
I would like to raise the question where to put the midas drivers.

 06 Nov 2005, Stefan Ritt, Suggestion, Where to put drivers?
|
[quote="Stefan Ritt"]We have both the example experiment and the MSCB Makefile which both expect to find the midas drivers under [b]$MIDASSYS/drivers/camac[/b]
or [b]$MIDASSYS/drivers/usb[/b]. The documentation does not explicitely mention to define MIDASSYS as [b]/usr/local[/b], but some people do it. That however
requires to put all drivers then under [b]/usr/local/drivers[/b], which is not the case in the current Makefile for midas. Do you think that we should |

18 May 2006, Stefan Ritt, Bug Fix, Fixed problems with reload of custom pages
|
We had a problem with custom pages and reloading of them. If they contain an ODB field which is editable, one can change the ODB value through the custom
page. The URL then contains a "?cmd=Set&value=x&index=x" section, which stays in the browser's address bar after the ODB value has been updated. If the
value changes later by some other means in the ODB, and one presses "reload" in the browser, the above URL gets executed again and the value gets changed |

25 May 2006, Stefan Ritt, Bug Fix, Fixed compiler warnings with gcc 3.4.4

I fixed a couple of compiler warning which came up with the new gcc 3.4.4. Seems like the compiler gets more and more picky. There a still warning left
in ybos.c and in mcnaf.c, which I leave to the original author ;) |

13 Jun 2006, Stefan Ritt, Info, ZLIB dependency modified

Due to recent problems with the ROME analyzer having zlib.h both in the
system and in the midas tree it has been decided to change the zlib policy in midas. By default, zlib support is not included in the midas analyzer. If
one want it (but I guess only very few experiments need that), one can do a

13 Jun 2006, Stefan Ritt, Info, Scheduler changed for slow control equipment
|
The schedule in mfe.c is used both for "normal" front-ends and for "slow-control" front-ends. Unfortunately it was only optimized for the first class. This
lead to the fact that the slow control equipment was read out at different speed depending if the run is started or not. Furthermore, the maximum readout
speed was somehow limited. This has been changed in the current version of mfe.c (SVN revision 3146). There are now two ways to control the readout speed |

23 Jul 2006, Stefan Ritt, Forum, File output for histories
|
[quote="Art Olin"]Basically we need the output from the mhist code. The most convenient, and possibly easiest implementation would be to select required
data (ID, variable, time range) in the midas history display, click a button requesting file output and input a file name. One might also want to specify
the interval time required.[/quote]
