Hi, I'd like to know what the current state of heap-shot profiling is in mono (3.12.1). I've been trying to use the heap-shot-gui tool [1] and it seems pretty broken. Here's what I've tried
## Instructions in heap-shot's README [2] These tell me to use $ mono --profile=heap-shot MyProgram.exe This doesn't work mono reports ``` The 'heap-shot' profiler wasn't found in the main executable nor could it be loaded from 'mono-profiler-heap-shot'. ``` Taking a look via strace. It seems mono tries to load ``/usr/lib/libmono-profiler-heap-shot.so`` which doesn't exist so I'm guessing this doesn't work any more? ## Instructions on Mono's website [3] These instructions tell me to use $ mono --gc=sgen --profile=log:heapshot MyProgram.exe This actually does generate a file (output.mlpd) but the heap-shot gui cannot open it. It throws an exception. ``` System.Exception: Unknown sample event type: 48 at MonoDevelop.Profiler.SampleEvent.Read (HeapShot.Reader.LogFileReader reader, Byte exinfo) [0x00000] in <filename unknown>:0 at MonoDevelop.Profiler.Event.CreateEvent (HeapShot.Reader.LogFileReader reader, EventType type, Byte extendedInfo) [0x00000] in <filename unknown>:0 at MonoDevelop.Profiler.Event.Read (HeapShot.Reader.LogFileReader reader) [0x00000] in <filename unknown>:0 at HeapShot.Reader.ObjectMapReader.ReadLogFile (IProgressListener progress) [0x00000] in <filename unknown>:0 at HeapShot.Reader.ObjectMapReader.Read (IProgressListener progress) [0x00000] in <filename unknown>:0 ObjectMapFileReader.Read (): Completed in 0.016 s ``` I saw there was a pull request [3] that tries to adapt heap-shot to the binary format outputted by 3.10.2, this seemed to work for 3.12.2 which I'm using. This seemed to fix my issue. Is there a reason this pull request has been completely ignored? Thanks, Dan.
