• Enable Concurrent mode for Namecheap

I did a limited amount of testing and it seems to work. I don't see any fields namecheap's struct that are updated after initialization.

Thanks @tlimoncelli I'll run some tests tomorrow if you like

That'd be great!

A good test would be:

• Compile with the -race flag: go install -race
• Use a dnsconfig.js file with multiple namecheap domains (at least 3... the more the better)
• Run the "race" version of the binary: dnscontrol preview --cmode concurrent

Thanks!

CONCURRENTLY gathering 5 zone(s)
SERIALLY gathering 18 zone(s)

I have 5 zones using both Namecheap DNS and registrar so looking good to me! I even ran it in a loop to offend the rate limit and that worked nicely too.

I'm using 3 other DNS providers but they don't have concurrency ticked on the docs so everything lines up.

Anything else you need me to try?

How about testing the other providers? :-)

Ah of course, I have tried netlify, hetzner, and digital ocean with no problem. The preview sure is fast now!
