 12 Dec 2012, Shaun Mead, Bug Report, ss_thread_kill() kills entire program
|
Hi, I'm having some trouble getting ss_thread_kill() to work properly. It seems
to kill the entire program instead
of just the thread. Here is a test program to show the error:

The Linux thread functionality was introduced by Konstantin, so he might have a better idea about that.
What I usually do is a graceful thread shutdown just by a flag. Like

14 Dec 2012, Robert Casperson, Bug Report, MIDAS does not function correctly on F17

When building MIDAS on Fedora 17 64-bit, the default zlib 1.2.5 shared library
is linked to. When recording data, the "/Logger/Channels/*/Statistics/Bytes
written" value does not get set correctly beyond the first few seconds of the

If is not so easy to get out of zlib how many bytes have been written actually. I used an undocumented function,
which breaks down on 64-bit systems.

26 Jul 2013, Konstantin Olchanski, Bug Report, abort on buffer overflow in odb.c::merge_records()
|
The odb.c function merge_records() has a fixed size array of 10000 bytes to handle the data and it
aborts with an assert() if passed data bigger than that. It is called from db_create_record() which
already allocates a data buffer of correct size for it's operations.

26 Jul 2013, Konstantin Olchanski, Bug Report, odbedit fixed size buffer overrun
|
odbedit uses a fixed size buffer for ODB data. If an array in ODB is bugger than this size,
db_get_data() correctly returns DB_TRUNCATED and there is no memory overwrite, but the following
code for printing the data does not know about this truncation and proceeds printing memory

13 Sep 2013, Thomas Lindner, Bug Report, mhttpd truncates string variables to 32 characters
|
I find that new mhttpd has strange behaviour for ODB strings.
- I create a new STRING variable in ODB through mhttpd. It defaults to size 32.

13 Sep 2013, Konstantin Olchanski, Bug Report, mhttpd truncates string variables to 32 characters
|
I can confirm part of the problem - the new inline-edit function - after you finish editing - shows you what you
have typed, not what's actually in ODB - at the very end it should do an ODBGet() to load the actual ODB

18 Sep 2013, Konstantin Olchanski, Bug Report, mhttpd truncates string variables to 32 characters
|
I confirm the second part of the problem.
Inline edit uses ODBSet(), which uses the "jset" AJAX call to mhttpd which does not extend string variables.

24 Sep 2013, Stefan Ritt, Bug Report, mhttpd truncates string variables to 32 characters

Actually this was no bug, but a missing feature. Strings were never meant to be extended via the web interface.
Now I added that feature to the current version. Please check it.

14 Nov 2013, Konstantin Olchanski, Bug Report, MacOS10.9 strlcpy() problem
|
On MacOS 10.9 MIDAS will crashes in strlcpy() somewhere inside odb.c. We think this is because strlcpy()
in MacOS 10.9 was changed to abort() if input and output strings overlap. For overlapping memory one is
supposed to use memmove(). This is fixed in current midas, for older versions, you can try this patch:

15 Nov 2013, Konstantin Olchanski, Bug Report, stuck data buffers
|
We have seen several times a problem with stuck data buffers. The symptoms are very confusing -
frontends cannot start, instead hang forever in a state very hard to kill. Also "mdump -s -d -z
BUF03" for the affected data buffers is stuck.

I was looking at something in the mserver and noticed that for remote frontends, for every periodic event,
there are about 3 RPC calls to bm_flush_cache().
