skipping bad records
most DB tables have a pointer skip table so you have a record of all the bad events if you wanted to replay them.
go modules
go.mod is similar to Gopkg.toml go.sum is similar to Goplg.lock Only direct dependencies are recorded in the go.mod file:
to make a file executable chmod -x .<filepathgit will track that its an executable.
you can then check thats its changed by:
diff --git a/.<path
old mode 100644
new mode 100755
alpine
alpine images dont come with bash so to write a script dont forget to use #!/bin/sh instead of #!/bin/bash
go has two flavours of typecasts:
raw.(*Session): take a pointer and assert that its concrete was already a Session, so you can use it as a sessionSession(raw): try and convert raw (not an interface, but another concrete type) into a session
GOROOT should be blank (defaults to /usr/local/go/ or similar), or the root of your go sources GOPATH should be blank (defaults to ~/go) or the root of your go user sources
