Thanks Mhd and agree with the suggestion.
However, we are trying to catch a bug which happens in production on k8s &
hence trying to explore different options.

What should happen after the method is added?
Will those types implementing the interface still implement it?

Cool.
BTW, there is another docs generator: https://github.com/go101/gold

Still a mistake there. All "MyReader" uses should be "*MyReader".

Sorry, the last 4 lines should be:
rs = (MyReader string)(rb)
_, _ = rs.Read(s)
rb = (MyReader []byte)(rs)
_, _ = rb.Read(bs)

In writing to a file option, we would periodically write the file as it
might turn out to be a huge file
for the entire life of the pod to flush at once.

That's a good idea, we can write to to a config map.

This might not
Because memory is reclaimed - the alloc is the “live” heap. TotalAlloc is a
cumulative counter of byte allocated - bytes freed do not affect the counter.

You need to write to a shared writable path that is global so when the pod
terminated the file is avail.
The http should work too if you map the ports properly. You can be able to
access the port from outside the pod.

I tested fyne on my Mac, hey didn't crash, that's a big plus with these
cross-platform GUI frameworks. The Look is somewhat different but with
some tweaks it could be made manageable. But for any large text-based
application with text styling and so forth I would use Electron or a

I had a look again at "Fyne". It seems to have improved a lot lately, in
particular the default size for fonts etc seems much better!
Thanks again for the suggestion.

You need a trace file. There are many ways to capture one.

A simple type conversion is 1 (one!) line and pretty clear.
Once you open this can of worms someone would like

Which sqlite driver are you using? That sounds like a bug.

I passed a string-type pointer (as last destination) to a sql.DB.Query call
which had a NULL value as field value. No error was returned and all other
fields got the appropriate values but the connection was silently closed.

I am having a memory leak issue in an app that reads data reports from a

My concern with pprof is it has to be made part of my process.
We had an issue where user requests were not reaching our http server

In this case what are my options if pprof server is not reachable when we

Hi Kurtis,
Thanks for the reply. I was giving C code to show the behavior of defunct

not have any associated resources or threads held.
Could be an issue with this Linux version, will check on the behavior in
Linux
I would start with making sure you can get the standard ‘go tool trace’ and
‘pprof’ working. Once you have those working ‘goanalyzer’ is an enhanced
version.
The docs are far more complete and substantial on the standard tools.
