Yes, it could made easier,
about that, its already great that all the tools we need

I'm loading a set of structs in memory and will be frequently using them
throughout the lifetime of the application and doing frequent 'queries'
against the set to get those where certain fields have certain values.

i agree to say its fallacies you can provide one func to quicksort string

in my understanding you are doing a quickSorter of Values you can compare.

Trust me guy, I've been light on you. I suggest you cool your jets. This
isn't my first rodeo. That is your only warning. This won't end with a
report to the CoC committee or some flame war on the forum. I cut much
deeper.

Great, thanks for letting me know.I'm just starting to experiment with
the software, so I have't had a chance to simulate real world conditions
yet. Are you running it under sustained or intermittent load? If
sustained, have you had any issues with memory, such as GC pauses or memory
leak

Hi, Tamas,
Thanks for the reply!
The key is a string for my current use.
After the data v is retrieved, it is compared with a new data coming from
the wire. And then based on the comparison, the new data, which is a newly
created piece of memory contains same type of data, will be sent to a C
Can you simplify it with map[string]interface{}?
Otherwise, the error indicates impedance mismatch between C++ and Go.
This is hard to debug - put printf everywhere, print the
allocated/freed/sent/received pointers (%p), and _reduce_ the program
line-by-line, till the error vanishes.

One difference is that I moved the rows.Scan call into the passed in

Other ideas:
1. set environment variable GODEBUG to cgocheck=2
2. try valgrind - maybe it picks something up (not sure how well it works)
3. try sanitizer
Thanks both!

This seems pretty trivial, tbh. You just parse the URL query string and
construct a JSON doc out of it?
Go's philosophy in general is that it's better to just write the code yourself
sometimes, even multiple times, than to pull in a dependency. Especially for
something like this.
Do you reme
Hi, folks,
I'm trying to track down a memory leak in a web server application, and I'm
having a hard time making sense of the output of the heap dumps emitted by
the net/http/pprof handlers. One of the dumps starts with:
heap profile: 5: 192080 [47408: 90679856] @ heap/1048576
1: 155648 [1: 1556
Thanks for letting me know that "left-pad" thing. I didn't know it before
you mentioned it here.
Parsing a URL string and constructing a BSON object are easy if the
criteria is like this:
A.B="foo" AND C.D=true
However, if the query is like this, I'm not sure if it still can be done
correctly

The functionality filago provides can be implemented with truss or strace.
filago offers a simpler (to many) way of getting to this information, and
can provide it in json as well.
