Add a flag to set the "no template params" option to c++filt.go

2

This is useful during experimentation.

See below. This package doesn't seem to be able to demangle this. ``` $ c++filt _ZN4zzzz16xxxxxxxxxxxxxxxxIPDoFiimzEJRiRmRPvEEENSt3__u9result_ofIFT_DpT0_EE4typeES9_DpOSA_ std::__u::result_of::type zzzz::xxxxxxxxxxxxxxxx(int (*)(int, unsigned long, ...) noexcept, int&, unsigned long&, void*&) $ c++filt --version...

Ability to generate JIT code with frame pointers to enable Linux perf stack unwinding

21

It seems that the JIT code generated by MKL DNN today does not set up frame pointers which means performance tools like Linux perf cannot unwind the stack by default....

Do not drop legacy profile alloc metrics when they are equal to in-use ones

1

Fixes #432. In #432 the user has a number of collected heap profiles in the legacy format that they ask pprof to merge and open and the merge fails. The...

Support flame graph as an output format

11

pprof currently supports flame graph visualization in the HTTP server mode. Sometimes it is desired to generate the flame graph visualization as a persistent report, likely as an SVG file.

The inline flag may be inaccurate if 'show' or 'hide' filter is used. Those filters may filter out some of entries in the line array causing a remaining entry (which...

Automated continuous testing of the web UI

#207 discusses future enhancements to the web UI. It would be good to improve the automated testing story for the feature so that contributors feel safe adding new functionality. Using...

Support opening Java heap dump files

2

Java heap dump files are in a custom format that pprof does not understand. It would be good to have a separate converter or ability to convert those files into...

This was mentioned in #130 which was closed since then so filing to track. For pprof symbolization to work on OSX it currently requires installing binutils (for gaddr2line) or llvm...

Running [this code](https://gist.github.com/aalexand/07c8e6eef3040f49b68a570e8c90daa6/5b518c1d8bc0bc6d383a3b4db9319f86d8f6fa9e) as `node sampling-heap-test.js loopalloc` (using node v8.11.1) I get the output below. Note that the heap size reported by the profiler is ever increasing and the gap...
