omg - we can retire identity.NewID()???? https://pkg.go.dev/crypto/rand@master#Text
cc @narrow pine @unreal pulsar 🎉

#

"Main module's version" also relevant to us - now you get v0.0.0-20250111143208-a7857c757b85+dirty instead of (devel)

#

t.Context() is also almost relevant to us but only does a very narrow part of testctx (cc @karmic hare) - it's just a context that gets canceled on test completion. I guess we can switch to it as the base context

gotta hope rand.Text() followed the spirit of that RFC4648 and not the letter, bc the letter has you use = for padding and it can break urls

#

actually, don't have to hope, i can read and it does indeed follow the spirit and not the letter

yea it's tiny: https://cs.opensource.google/go/go/+/master:src/crypto/rand/text.go;l=14

#

os.OpenRoot is also a very nice feature... makes it significantly less spooking touching the filesystem on a web-exposed server... although like should you really be doing that in the first place lol

#

omfg they added fake clocks so you don't have to dep inject fake time any longer

#

lol yea was just gonna say

#

the way it's integrated with goroutines blocking is really slick

#

so you don't even need to babysit time advancing

#

really a lot of good stuff, VCS info in BuildInfo.Main.Version is also mega convenient... i think i've seen like 5 different ways ppl do that same thing themselves to get shas into their logs

#

but in terms of time saved i think the fake clock addition wins the release

#

soooo when can we upgrade? I'd like to see how the t.Context() fits into testctx while testctx is still loaded in my brain

tropic bloom Jan 15, 2025, 5:12 PM

#

should be out next month, we usually upgrade pretty much immediately

^ tool dependencies seem kinda interesting 🤔

#

kinda interesting to imagine integrating that into common dagger commands

#

since i could definitely see language servers picking up these tools as code actions

And @small nest, look at what the author built for the running examples: https://codapi.org
