 05 May 2005, Konstantin Olchanski, Bug Fix, fix: minor bit rot in the example experiment
|
I fixed some minor bit rot in the example experiment: a few minor Makefile
problems, make the analyzer use the current histogram creation macros, etc. I
also added startup and shutdown scripts. These will be documented as we work

02 Aug 2005, Konstantin Olchanski, Bug Fix, fix odb corruption when running analzer for the first time
|
I have been plagued by ODB corruption when I run the analyzer for the first time
after setting up the new experiment. Some time ago, I traced this to
mana.c::book_ttree() and now I found and fixed the bug, fix now commited to

18 Aug 2005, Konstantin Olchanski, Bug Fix, fix race condition between clients on run start/stop, pause/resume
|
It turns out that the new priority sequencing of run state transitions had a
flaw: the frontends, the analyzer and the logger all registered at priority 500
and were invoked in essentially a random order. For example the frontend could

07 May 2006, Konstantin Olchanski, Bug Fix, Update & add VME drivers
|
I commited fixes for a few minor compilation errors in the VME drivers
(vmicvme.c, etc)
I also added new drivers for the v513 latch and v560 scaler that I wrote for

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. |

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 |

There is a crash in odbedit when loading some xml odb files: a missing check for NULL pointer when
loading an array of strings and one of the array elements is blank. This check is present when loading
other string values. Here is the diff:

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 ;) |

When using mhist interactively, I could not look at array data:

was not asked, zero was assumed,

08 Jun 2006, Konstantin Olchanski, Bug Fix, fix compilation of musbstd.h, add it back to libmidas
|
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. |

08 Jun 2006, Konstantin Olchanski, Bug Fix, commit latest ccusb.c CAMAC-USB driver
|
I commited the latest driver for the Wiener CCUSB USB-CAMAC driver. It
implements all functions from mcstd.h and has been tested to be plug-compatible
with at least one of our CAMAC frontends. K.O. |

08 Jun 2006, Konstantin Olchanski, Bug Fix, updated vmicvme driver

I commited the latest VMIC VME driver we use at TRIUMF. It has working support
for D32 and D64 DMA and can move data from the SIS3820 multiscaler through the
MIDAS frontend at > 30 Mbytes/sec on our VMICVME-7805 machines. The actual DMA

28 Jul 2006, Konstantin Olchanski, Bug Fix, mhttpd: use more strlcpy(), fix a few bugs
|
While investigating the mhttpd password error with the MacOS Safari browser, I
found that it was caused by an strcpy() buffer overflow. With Stefan's blessing,
I now converted most uses of strcpy() and strcat() to strlcpy() and strlcat().

31 Jul 2006, Konstantin Olchanski, Bug Fix, Fix user memory corruption in ODB

We have been seeing consistent user memory corruption while setting up a new
experiment. This has been traced to a user memory overwrite in ODB db_set_data()
function and this problem is now fixed. This error was triggered by our frontend

01 Aug 2006, Konstantin Olchanski, Bug Fix, User-tunable buffer sizes
|
By default, MIDAS creates shared memory event data buffers of default size
EVENT_BUFFER_SIZE defined in midas.h and until now making of large data buffers
for high data rate or large event size experiments was complicated.
