Today, the build gates are obsolete. I found this out after seeing someone flag this on a commit setting -static-libgcc. Note that the Linux builds came in at the expected amount of disk space utilization, so I did not touch the values for them.
This PR aims to readjust the build gate disk space per-host estimates for darwin and mingw based on some testing I did locally in my build VM.
Details: (Copied from https://github.com/kevkevinpal/bitcoin/issues/200):
I ran HOSTS="x86_64-w64-mingw32" ./contrib/guix/guix-build
After (+10 GiB):
0Filesystem 1G-blocks Used Available Use% Mounted on
1/dev/sda5 512G 98G 393G 20% /gnu/store
These numbers makes this change seem reasonable (1.5x safety factor):
0- *mingw*) required_KiB=7600000 ;;
1+ *mingw*) required_KiB=15728640 ;;
Then I ran HOSTS="aarch64-linux-gnu" ./contrib/guix/guix-build.
After (+6 GiB):
0Filesystem Size Used Avail Use% Mounted on
1/dev/sda5 512G 104G 387G 22% /gnu/store
Then I setup the SDK for macOS. This established a new before snapshot of disk use:
0Filesystem Size Used Avail Use% Mounted on
1/dev/sda5 512G 116G 375G 24% /gnu/store
Then I ran HOSTS="x86_64-apple-darwin" ./contrib/guix/guix-build.
After (+5 GiB):
0Filesystem Size Used Avail Use% Mounted on
1/dev/sda5 512G 121G 370G 25% /gnu/store
IMO, this is grounds for updating this (5 GiB * 1.5x safety factor):
0- *darwin*) required_KiB=440000 ;;
1+ *darwin*) required_KiB=8388608 ;;
