 30 Oct 2003, Stefan Ritt, , Fixed several potential problems for ODB corruption
|
I just realized that db_set_value, db_set_data, db_set_num_values and
db_merge_data do not check for num_values == 0. With such a parameter the
ODB can become corrupted, since zero length ODB entries are not allowed. I

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 |

I the agdaq system I see memory corruption in the mlogger. There were at least two bugs: one
memory allocation error in mxml and one incorrect memset() in mlogger.cxx. The mxml bug is fixed
in the mxml repository, mlogger.cxx bug is fixed in the midas-2017-10 branch.

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 ;) |

Prior to odb.c rev 4829 and mhttpd.c rev 4830 committed a few minutes ago, HTML javascript
ODBGet("/non_existant_odb_entry") caused ODB corruption requiring ODB reload from backup file.

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

27 Nov 2008, Konstantin Olchanski, Bug Fix, Fix ss_file_size() on 32-bit Linux
|
It turns out that on 32-bit Linux, ss_file_size() returns the wrong answer for
files bigger than 2 GB (4GB?). The Linux stat() system call returns an error
(which is ignored) and bogus file size data (returned to the caller).

That does not work if _LARGEFILE64_SOURCE is not defined. In that case, the compiler

Some time ago, I accidentally introduced a bug in mfe.c- if there is data
congestion in the system, mfe.c can exit with the error "bm_flush_cache(ASYNC)
error 209" because it did not expect the valid return value BM_ASYNC_RETURN

I commited minor fixes for building MIDAS on MacOS 10.4.7:
1) there is no linux/unistd.h
2) gcc 4.0.0 does not like "struct { ... } var;" although "struct Foo { ... } var;" is fine

While watching "The Wizard of Oz", the greatest movie ever made, I took a shot at building
midas on my macosx computer. After stumbling on a few small and on a few hard problems, I
built almost everything. However, odb does not work- some further debugging is in order.
