* Better handling of invalid XML: a) prevent infinite loop on EOF; b) better ↵Oren Hurvitz2015-08-111-0/+10
| | | | | | | | logging If the XML was truncated for some reason then ExecuteReadProcessors() would get into an infinite loop, using high CPU. Now it detects EOF (and several other error cases) and aborts. The rest of the changes just improve logging of XML in case of errors, so that we can see what the bad XML is.
* Have osAvatarName2Key check the cache first, even for foreign usersOren Hurvitz2015-08-071-1/+24

* For monitoring purposes, start non-timeout tasks (which do not currently use ↵Justin Clark-Casey (justincc)2014-09-051-30/+0
| | | | | | | a threadpool) via Watchdog.RunInThread() rather than Util.RunThreadNoTimeout() The functionality is the same but this allow us to monitor such tasks via "show threads" and abort them for test purposes, etc. Also extends thread names to provide more info (e.g. SendInitialDataToClient says what client the task is for).
* Ignore whitespace when reading serialized XML objects.Justin Clark-Casey (justincc)2014-08-291-5/+5
| | | | | | This was previously effectively being done by XmlDocument in the multiple passes through the XML. This change tells XmlReader to ignore whitespace. This also means changing arguments to use XmlReader instead of XmlTextReader (a descendent of XmlReader) directly. XmlReader.Create() has been the recommend way to create XML readers since .NET 2.0 as per MS SDK and is the only way to specific ignore whitespace settings.
* Better logging of threadpool activity in Overload mode: if we didn't log ↵Oren Hurvitz2014-07-211-1/+7
| | | | "Queue threadfunc" for a particular thread then don't log "Run threadfunc" or "End threadfunc" for that thread either.

* Use thread-safe version of .NET Random as the SDK class is not thread-safe.Justin Clark-Casey (justincc)2014-07-141-1/+1
| | | | | | | | As per http://msdn.microsoft.com/en-us/library/system.random%28v=vs.100%29.aspx, the .NET Random class is not thread-safe. If called by multiple threads at once, methods may return 0. Except for llRand(), other OpenSimulator code did not lock before calling a shared Random instance. This commit adds a ThreadSafeRandom class that extends Random but does internal locking so that it is thread-safe. This change is invisible to existing callers and the explicit locking in the llFrand() implementation is now redundant.
* Actually call Close() for shared region modules when the simulator is being ↵Justin Clark-Casey (justincc)2014-07-021-1/+6

* Restore overload mode accidentally disabled in a prior commit. Add a newMelanie2014-04-251-2/+4
| | | | | | config option, LogOverloads, to log when a thread pool overload occurs. This option defaults to "True" because the logging data is useful for diagnosing threading issues.

* - Increased the threadpool timeout to 10 minutesOren Hurvitz2014-03-261-1/+1
| | | | - Changed a few places that launch long-lasting threads to skip the timeout altogether
* Improved logging of HTTP requestsOren Hurvitz2014-03-251-0/+40
| | | | | | | | | | | - MemoryBuffer isn't seekable, so we can't log it. Log the string instead. - Handle compressed streams - Don't attempt to dump binary data. Either don't log it at all (if we know it's binary), or at least convert non-ASCII characters to ASCII. - Log responses to HTTP requests - Use the same log prefix for all of these log messages ("[LOGHTTP]"), to make them easy to see at a glance - Increased the snippet length to 200 (80 doesn't show enough), and add "..." only if the message was actually truncated Resolves http://opensimulator.org/mantis/view.php?id=6949

* Added a watchdog to abort slow threads in the main thread poolOren Hurvitz2014-03-251-11/+269
| | | | | | | | | | If a task in the thread pool hangs then it will permanently take up one of the threads. If this happens repeatedly then the thread pool will become exhausted and OpenSim will fail. This watchdog terminates threads in the thread pool that have been executing for over a minute (which probably means they're hung). Resolves http://opensimulator.org/mantis/view.php?id=6945

* Get the full viewer name even if it's (incorrectly) sent in the 'Channel' fieldOren Hurvitz2014-03-241-0/+32
| | | | | | Recent versions of Firestorm and Singularity have started sending the viewer name in the 'Channel' field, leaving only their version number in the 'Viewer' field. So we need to search both of these fields for the viewer name. This resolves http://opensimulator.org/mantis/view.php?id=6952
* Revert "Simplify DoubleQueue to eliminate redundant sempahore work."Justin Clark-Casey (justincc)2014-03-191-7/+27
| | | | | | This reverts commit 52b7b40034ddbb21d06b11ddc4eb6d766b0f616d. Got the semantics wrong - the sempahore is required so that the blocking thread waits for a signal.

For example, if a simulator crashes and they never login/logout again. To counter this somewhat, only users continuously online for less than 5 days are shown.
