* Huge stability push... all (known) paths have been tested heavily on linux with tsan and every single found race condition report has been fixed. Lots of locks have been added/moved/changed and some instances of things have been leaked on purpose to prevent tsan reports during shutdown
* More efficient storage proxy implementation which immediately forward segments to clients once they are available in proxy
* Added UbaAgent -command=x which can be used to send commands to host. Supported commands are "status"which prints out status of all remote sessions. "abort/abortproxy/abortnonproxy" that can be used to abort remote sessions and "disableremote" to have host stop accepting more helpers
* Fixed scheduler::stop bug if remotes were still requesting processes
* Added support for process reuse on linux/macos
* Added support for Coordinator interface and dynamically load coordinator dll in UbaCli
* Restructured code a little bit to be able to queue up all writes in parallel
* Added Show create/write colors to visualizer (defaults to on)
* Fixed so write file times are visualized in visualizer
* Improved socket path for visualizer
* Improved a lot of error messages
* Fixed double close of memory handle in StorageServer
* Changed some ScopedWriteLock to SCOPED_WRITE_LOCK (same for read locks)
* Fixed some missing cleanup of trace view when starting a new trace view in visualizer
[CL 32137083 by henrik karlsson in ue5-main branch]
* Added session notification message to be able to see why client is about to go away.. hopefully this will help us identify if there are crashes happening on remotes that we don't track
* Added ApplicationRules::AllowStorageProxy and changed so .obj files are never going through the storage proxy on fetch (they are only read by one process so no point feeding them through the proxy
* Fixed the file write-through code and gave the #if 0 a name (#if UBA_USE_WRITE_THROUGH).. still disabled since it didn't give any benefits enabling it
[CL 32025069 by henrik karlsson in ue5-main branch]
* Fixed missing assignment of process weight in assignment operator.. this caused remote machines to think all processes had the processor weight of 1 which is wrong for processes like cl.exe which cost 1.5 processors.
[CL 32024695 by henrik karlsson in ue5-main branch]
* Changed so in-process storage proxy is using memory network backend for communication with client
[CL 31982524 by henrik karlsson in ue5-main branch]
* Added __try/__catch to UbaAgent main and disabled the other seh exception handling to see if we get more luck with this on wine/linux
* Moved code from SessionClient ctor to start function to get around ordering issue where session can get connection callback in ctor
* Compile fix for test code caused by previous changelist
[CL 31982469 by henrik karlsson in ue5-main branch]
* Added support for handling server side messages and send response later
* Changed so storage proxy errors are muted when disconnected
* Improved error messages
[CL 31981923 by henrik karlsson in ue5-main branch]
* Fixed race condition in UbaNetworkClient related to message ids and returning message ids after use
* Implemented network backend that is using memory for communication (will be used between client and proxy server when running inproc)
* Added connection uid provided by network backend to be able to improve error messages
* Added NetworkBackend GetTotalSendAndRecv that can be used to fetch all traffic on backend
[CL 31981782 by henrik karlsson in ue5-main branch]
* Extracted work tracker out from work manager so it can be used for multiple work managers when running with proxies
[CL 31981685 by henrik karlsson in ue5-main branch]
* Added PrefetchVirtualMemory function
* Fixed bug where code writing callstacks checks end of module to figure out if address belongs to module
* Changed so FileAccessor::CreateMemoryWrite set always allow read because you can't create file mappings that are write-only
* Added option to scheduler to force all runs to run native
* Fixed so bottleneck class has enter/leave function
* Added ScopedReadLock::Enter
* Moved LogWriter to its own file
* Visualizer - Fixed so when hovering over timeline time under pointer is showing
* Visualizer - Fixed so hovering over work records shows name, start and duration
* Visualizer - Added context menu item that can show/hide text of process bars
* Improved assert message
* Changed so lock is not on stack but is leaked to prevent shutdown warnings in debug
* Added missing includes
[CL 31981637 by henrik karlsson in ue5-main branch]
* Changed NetworkMessage to use a callback for when message is done and moved event out of message. This is a change in preparation for UbaStorageProxy optimization
[CL 31865186 by henrik karlsson in ue5-main branch]
* Added potential race condition fix that could happen during certain disconnect situations in storage proxy
* Added Deploy-Linux.bat that can be used to build all linux binaries. It also enables tsan when running "Deploy-Linux.bat debug"
[CL 31832747 by henrik karlsson in ue5-main branch]
* Reduced contention in SessionClient when testing if processes are done and spawning new processes
* Changed so FileMappingBuffer is lazily closing mapped memory. For some reason these calls end up being very expensive and we don't have to close them straight away
[CL 31796195 by henrik karlsson in ue5-main branch]
* Changed so sending in a 0 workercount will use logical core count
* Cleaned up code around work tracking
[CL 31796079 by henrik karlsson in ue5-main branch]
* Elevate thread priority for the threads doing all the networking to make sure proxy and host are prioritizing receiving/sending network data
[CL 31796023 by henrik karlsson in ue5-main branch]
* Changed so StorageProxy is not reading entire files first before sending them out to clients. Instead it now lazily loads each segment based on requests and send it
[CL 31795976 by henrik karlsson in ue5-main branch]
* Added Uba NetworkClient::StopAll
* Fixed shutdown race condition in NetworkClient
* Changed client work count from 16 to no of logical cores
[CL 31795950 by henrik karlsson in ue5-main branch]
* Changed so all ScopedReadLock and ScopedWriteLock are macros (SCOPED_READ_LOCK and SCOPED_WRITE_LOCK).. this to be able to add code around the lock to measure contention. Contention testing code can be enabled by setting UBA_TRACK_CONTENTION to 1
[CL 31795889 by henrik karlsson in ue5-main branch]
* Changed aws code to use token for meta data queries. Some of our AWS machines require this and it doesn't hurt to use it everywhere
[CL 31757296 by henrik karlsson in ue5-main branch]
* Fixed deadlock in client that could happen if client connecting timed out at the same time as it managed to connect. There were lots of race conditions in this code around these scenarios. Current implementation should be properly fixed
[CL 31756699 by henrik karlsson in ue5-main branch]
* Disabled custom signal handler in UbaHost in case this is the reason we get crashes in ubt
* Changed some logging from Info to Detail
[CL 31742437 by henrik karlsson in ue5-main branch]
* NetworkBackendTcp - Changed so when having failed connection we wait for socket thread before taking lock to delete it.
* NetworkBackendTcp - Removed check for 0 connections. That was a hack and now all code should properly wait
* Changed infinte wait of event to 60 seconds and output error if it times out..
* Removed NetworkBackend::Close. This should never be done on the outside. Outside should always call shutdown and then wait for disconnect callback
* Moved shutdown of socket to outside lock to prevent deadlock
[CL 31731469 by henrik karlsson in ue5-main branch]
* Fixed shutdown issues where client and server did not wait for connection to be closed before closing down
* Added error handling for trying to decompress bad cas files
