I observe that the mhttpd passwords do not work correctly for the Safari web browser on MacOS 10.4.7:
Safari 2.0.4 (419.3). For example, I cannot submit elog messages- the system gets stuck on the
"Password" page. The Safari browser in MacOS 10.3 works fine. Mozilla/Firefox works fine. (Also would be

Hi. When I attach the file below, Mix+Positronorig.xlx to an elog, and then open it or download it to disk, the file, 060... is severely truncated.

The ALPHA experiment at CERN has recently adopted MIDAS, and the history data in numerical form is needed by the collaboration. Furthermore the DAQ is running
under linux and most collaborators are windows or mac users, so it should be available in a platform independent way.

[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]

Hi Art,
you can make the process somewhat less painful by using the Plink (from PuTTY) to run mhist as a remote command, piping the output to a local file:

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 |

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

Due to recent problems with the ROME analyzer having zlib.h both in the

one want it (but I guess only very few experiments need that), one can do a

I fixed the compilation of musbstd.h (it required -DHAVE_LIBUSB on Linux, but
nothing knew about defining it) and put musbstd.o back into libmidas (USB
support should be part of the standard base midas library). K.O. |

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 |

18 May 2006, Konstantin Olchanski, Bug Fix, removed a few "//" comments to fix compilation on VxWorks
|
Our VxWorks C compiler (gcc-2.8-something) does not like the "//" comments. Luckily, on VxWorks, we
only compile a small subset of midas, so there is no point in banning all "//" comments. But I did have to
convert a couple of them to /* commens */ in odb.c to make it compile. Changes to odb.c commited. K.O. |

11 May 2006, Konstantin Olchanski, Bug Report, MIDAS and Fedora 4

Fellow Midasites- we are receiving reports that current Midas sources do not compile on Fedora 4 (and 5?)
with errors "invalid lvalue in assignment". It looks like the new compilers reject what looks to my eye like
perfectly valid C code that we have been writing since the beginning of C. Any suggestions on the best fix?
