pvadriver's Introduction

pvaDriver

An EPICS areaDetector driver for importing an EPICSv4 NTNDArray via pvAccess into areaDetector. It does so by creating a monitor on the specified PV. It can be used with the NDPluginPva to copy NDArrys from one IOC to another, but can also be used to allow any EPICS V4 server to send NTNDArrays to the IOC.

pvadriver's Issues

Poor performance with default request type queue size

Hi,

I've been playing around with pvaDriver today, transporting 0.5MB images between two areaDetector IOCs with and without LZ4 compression.

I saw poor performance with the pvaDriver with even a low frame rate of 100Hz (only 50MB/s), in that I was dropping arrays every few seconds.

Then I made this change in pvaDriver:

diff --git a/pvaDriverApp/src/pvaDriver.cpp b/pvaDriverApp/src/pvaDriver.cpp
index 02b5d4a..278c21f 100644
--- a/pvaDriverApp/src/pvaDriver.cpp
+++ b/pvaDriverApp/src/pvaDriver.cpp
@@ -23,8 +23,8 @@
#include <epicsExport.h>
#include "pvaDriver.h"

-//#define DEFAULT_REQUEST "record[queueSize=100]field()"
-#define DEFAULT_REQUEST "field()"
+#define DEFAULT_REQUEST "record[queueSize=100]field()"
+//#define DEFAULT_REQUEST "field()"

And that worked wonders. I was able to reliably run at 100Hz, 800Hz and even 1500Hz without dropping frames.

It seems like that driver was used with queueSize=100 at some point but that it was commented out.

I think this parameter could be made configurable as an argument to pvaDriverConfig(). Does that sound reasonable? If so, I can make a pull request and test it.

connectPv exception on IOC start up

I am currently trying to update DLS to ADCore 2-6, plus the other dependencies that come with that.

I have two IOCs, one with a SimDetector and pvaPlugin, the other with a pvaDriver, PosPlugin and HDF5Plugin. It works OK with our most recent internal ADCore 2-4 release. (We imported pvaDriver at this commit dls-controls/ADCore@834944c). The PvName is set, reports up and I am able to get frames and capture an image.

When testing the pvaDriver in its new repository I got the following error:

2017/04/05 16:09:17.358 pvaDriver::connectPv exception initializing monitor: 0 or empty channel name
2017/04/05 16:09:17.359 MAP-DI-TEST-01:CAM:PvName devAsynOctet::writeIt failed pvaDriver:writeOctet: status=3, function=87, value=

and on start up, the PvName is empty and reports as Down and I can't get any frames through. Here is the console output where I have added some debug statements; PvName and 4 numbers throughout the connectPv function and the value asked to set in the writeOctet function.

I tried playing with the pvaDriver source to find the problem and it seems like, between pvaDriverConfig() and connectPv() being called a second time, something is calling writeOctet to set PvName to a blank string. I added a check to refuse to set PvName if the value is blank and that seems to fix the issue. The PvName is blank, but reports up and I can get frames and capture an image.

I tried checking out the ADCore 2-6 and pvaDriver 1-1 releases, alongside the DLS configure/ folder and I get the same issue.

Missing NULL test of NTNDArray::wrap()

NTNDArray::wrap() can return NULL. If for some reason it does, eg. I give it a somehow "incompatible" definition, then SIGSEGV follows.

pvaDriver/pvaDriverApp/src/pvaDriver.cpp

Lines 244 to 258 in e0819d2

    
           NTNDArrayConverter converter(NTNDArray::wrap(update->pvStructurePtr)); 
        
           NTNDArrayInfo_t info; 
        
           try 
        
           { 
        
               info = converter.getInfo(); 
        
           } 
        
           catch(...) 
        
           { 
        
               asynPrint(pasynUserSelf, ASYN_TRACE_ERROR, 
        
                       "%s::%s failed to get info from NTNDArray\n", 
        
                       driverName, functionName); 
        
               monitor->release(update); 
        
               continue; 
        
           }

Also, it is bad form to swallow exception messages like this. I see no reason to catch anything other than std::exception. If you ever find that PVD or PVA throws something which doesn't derive from std::exception, then please report this as a bug.
