What is actually library_index.json used for ? Loading it takes extremely long on Raspberry Pi

rudolfsAER · January 23, 2025, 12:18pm

Hello!

I am running arduino-cli 1.1.1 on a Raspberry Pi 4. Basically all commands are very slow. Using --verbose and --log I have come to the conclusion that LoadIndex for library_index.json is causing the slow down. I have cases where LoadIndex takes around a minute for a simple command such as "board list".

Thus my question is, what is LoadIndex with library_index.json actually used for? Is it strictly necessary for correct compilation and upload ?

I have removed the contents of library_index.json, leaving an empty file. This works and the compilation and upload ar still functional.

I believe that library_index.json is part of the mechanism for checking whether library updates are available for download

Hi @rudolfsAER. As @UKHeliBob said, this file provides the data that is used for most of the arduino-cli lib commands:

https://arduino.github.io/arduino-cli/latest/commands/arduino-cli_lib/

These commands provide command line functionality equivalent to the Arduino IDE's "Library Manager" feature.

I think the only other time it is used is for arduino-cli compile, under the following specific conditions:

You are using a "build profile"
Library dependencies specified by the build profile have not yet been installed in the build profile's isolated dependencies environment

There are 7.5k libraries (each of which may have multiple releases) in the index, so it is a significant quantity of data for Arduino CLI to process.

Thank you for your answer!

I think there may be a bug in the GO implementation for ARM on Raspberry Pi. easyjson Unmarshal has very unpredictable performance. It parses the same library_index.json, but I have cases where it takes 5 minutes and an immediate following run takes 30 seconds, and a third run takes 2 minutes. I have done some GO profiling on the arduino-cli and it seems that it is an issue with GO memory allocation and garbage collection. I have checked for swap usage and thermal throttling, both are not an issue.

Either way for my needs the sketch does not use many libraries and the ones that are used should not be updated dynamically, thus having an empty library_index.json works for me.

Are there any more elegant options, such as a hidden flag to disable LoadIndex in arduino-cli?

Using 1.1.1 on an Pi4 here, and I can't say I've noticed any undue holdups in compilation or upload. Certainly none I could lay at the library index's doorstep. Even doing a library search is finished in about 16 seconds.

I cannot upload files as a new user, so here I have pasted the output for a simple board list. I have also added some version information.

As you can see the LoadIndex is the bottle neck.
