Ville Vesilehto b21c752d7f chore(lint): enable gosec (#7792 )

Enable "gosec" linter.

Exclude:

- All G115 (integer overflow) findings, to be fixed separately.

Add targeted gosec annotations for:

- non-crypto math/rand usage
- md5 used only for file change detection
- G114 ("net/http serve with no timeout settings"), to be fixed
  separately.

Other findings fixed.

pprof

Name

pprof - publishes runtime profiling data at endpoints under /debug/pprof.

Description

You can visit /debug/pprof on your site for an index of the available endpoints. By default it will listen on localhost:6053.

This is a debugging tool. Certain requests (such as collecting execution traces) can be slow. If you use pprof on a live server, consider restricting access or enabling it only temporarily.

This plugin can only be used once per Server Block.

Syntax

pprof [ADDRESS]

Optionally pprof takes an address; the default is localhost:6053.

An extra option can be set with this extended syntax:

pprof [ADDRESS] {
   block [RATE]
}

block option enables block profiling, RATE defaults to 1. RATE must be a positive value. See Diagnostics, chapter profiling and runtime.SetBlockProfileRate for what block profiling entails.

Examples

Enable a pprof endpoint:

. {
    pprof
}

And use the pprof tool to get statistics: go tool pprof http://localhost:6053.

Listen on an alternate address:

. {
    pprof 10.9.8.7:6060
}

Listen on an all addresses on port 6060, and enable block profiling

. {
    pprof :6060 {
       block
    }
}
