37. (Mary Hinton) 10 May 2002 - Fixed the problem in the new version of |
| |
pegasus_gettimeofday(struct timeval *tv)function for the Windows |
| |
platform. The new implementation was implemented for higher resolution |
| |
for performance statistics. However, it was causing an intermittent |
| |
hang in the ThreadPool test on the Windows platform.When (long int) |
| |
is changed to (__int64), the tv_usec variable of timeval struct has |
| |
the correct value. |

38. (Roger Kumpf - HP) 13 May 2002 - To eliminate the possibility of |
| |
collisions (and subsequent corruption) when different threads |
| |
concurrently update the ArrayRep reference count, I added a Mutex |
| |
to the ArrayRep structure. This Mutex gets locked in the inc() |
| |
and dec() methods that manage the reference count. |
| |
|
| |
After adding the Mutex, the "mysterious" memory problems seemed to clear |
| |
up. This seems like a very good thing. However, note that the addition |
| |
of the Mutex adversely affects performance (nearly 2:1). I tried using |
| |
an AtomicInt for the reference count, but that seemed to yield even worse |
| |
performance on my system. |
| |
|
| |
Anyone should feel free to optimize the performance of the locking in |
| |
the ArrayRep structure. Since I believe this locking is required for |
| |
proper operation, I've added the Mutex for all platforms. Note that I |
| |
had to comment out the assert statements in internal_dq.h to avoid a |
| |
circular header file dependency (Array.h->IPC.h->internal_dq.h-> |
| |
Exception.h->String.h->Array.h). |
| |
|
| |
39. (Roger Kumpf - HP) 13 May 2002 - Removed operator int() methods from |
| |
all CIM* classes. These methods had been causing a number of difficult |
| |
to find defects, including the use of the wrong versions of the methods |
| |
in Memory.h by the Array template (leading to major memory leaks). |
| |
|
| |
In general, it is dangerous to define a casting operator method that |
| |
loses so much information, because the compiler will apply the cast |
| |
at will in an effort to match types. I've replaced all instances of |
| |
the int cast operator with isNull() methods. |

40. (Nag Boranna - HP) 14 May 2002 - HP-Nag: Added SSL Certificate verification |
| |
code in TLS.cpp, created a new class CertificateInfo to pass certificate |
| |
information to the client's call back function. Modified CIMServer.cpp and |
| |
the Command lines that are using SSLContext to pass a call back function. |
| |
Fixed few display messages in CIMConfigCommand.cpp to show meaningfule |
| |
messages when CIM server is not running. |
