I get a SHA mismatch for obb v0.0.3 when upgrading via brew.

ordnungswidrig 2022-03-10T08:36:46.614899Z

user=> (format "%064x", (BigInteger. "cafebabe123" 16))
"00000000000000000000000000000000000000000000000000000cafebabe123"

Can you make sure to purge your local brew recipes

borkdude 2022-03-09T16:46:59.355789Z

I pushed a new one but you gotta clear your local one

borkdude 2022-03-09T16:47:29.373549Z

The sha-1 in the formula is now: "564ffc2038300fef50e074b9cd4a3fa7c426817989691c531b4032180afd731"

borkdude 2022-03-09T17:01:43.009399Z

maybe removing and re-installing will help

lread 2022-03-09T17:50:51.227549Z

Tried uninstalling, but still having issues:

brew install babashka/brew/obb

That extra leading zero seems suspect!

borkdude 2022-03-09T18:00:46.488089Z

fuck, indeed

can you maybe take a look in https://github.com/babashka/homebrew-brew, if you want? I'm having dinner. The bb update-obb task creates the recipe. I'll be back in a hour...

lread 2022-03-09T18:15:52.997809Z

sure, I’ll take a peek

lread 2022-03-09T18:20:51.026539Z

Ya looks like https://github.com/babashka/homebrew-brew/blob/daba814cdc31febf0916fe865166289d756336ba/bb.edn#L51.

borkdude 2022-03-09T18:26:55.768809Z

but why are they needed by brew :(

borkdude 2022-03-09T18:27:16.247679Z

should we format the string using leading zeroes using format ?

lread 2022-03-09T18:28:06.925729Z

Ya I think that would do the trick…

lread 2022-03-09T18:29:22.286199Z

… %02x?

borkdude 2022-03-09T18:33:45.159619Z

fixed it by shelling out to sha256sum

lread 2022-03-09T18:33:54.150839Z

I guess maybe a sha256 is 256 bits which means it is always 64 characters long?

borkdude 2022-03-09T18:34:16.017439Z

please try installing again

ok, the fixed hex fn:

(defn ->hex [file]
                   (let [digest (java.security.MessageDigest/getInstance "SHA-256")
                         hash (.digest digest (fs/read-all-bytes file))
                         hex (.toString (BigInteger. 1 hash) 16)
                         zeroes (str/join (repeat (- 64 (count hex)) "0"))
                         hex (str zeroes hex)]
                     hex)))

borkdude 2022-03-09T18:42:32.649509Z

at least I don't have to worry about linux/mac this way

lread 2022-03-09T18:44:08.701919Z

ya that works, and no wondering about how format might behave.
