[request] Optimize library size (arduino-cli fails install with default timeout)

[MarkWendler]

Summary

Hi,

CI/CD (Jenkins and Github workflow) fails due to arduino-cli timout with Silabs arduino library download.

Process:

$arduino-cli core install SiliconLabs:silabs
Downloading packages...
SiliconLabs:gcc-arm-none-eabi@12.2.rel1 SiliconLabs:gcc-arm-none-eabi@12.2.rel1 already downloaded
SiliconLabs:openocd@0.12.0-arduino1-static SiliconLabs:openocd@0.12.0-arduino1-static already downloaded
SiliconLabs:simplicitycommander@1.16.4 SiliconLabs:simplicitycommander@1.16.4 already downloaded
SiliconLabs:silabs@3.0.0 18.43 MiB / 574.15 MiB [====>-------------------------------------------------------------------------------------------------------------------------------------------]   3.21% 03m19s

Error message:

SiliconLabs:silabs@3.0.0 context deadline exceeded
Error during install: context deadline exceeded

Workaround: (Not working at some cloud based CI/CD)
Change defaulat timout
arduino-cli config set network.connection_timeout 600s

Request:
Downsize the Silabs Aurduino library release.

Hello @MarkWendler,

Thank you for your report! Unfortunately we cannot take responsibility for your CI/CD pipelines failing in this case. From the logs you provided it looks like your internet connection / download speed is extremely slow (0,24Mb/s) - thus you're hitting the timeout. Also, it would be impossible to optimize the core to fit in just 18.43 MB.
The package size of the core is bound to grow in the future as we're planning to add support for more boards - and we cannot make any package size guarantees. This issue is entirely out of scope for us to fix as we cannot cater to each of our users custom CI/CD pipelines.

My advice to resolve your issues would be the following:

• Increase the timeout value
• Upgrade your internet connection to something faster
• Move your CI/CD to the cloud using instances with fast and reliable internet connection
• Cache the core archives in a local network install server instead of hitting up GitHub each CI/CD run
