ARDUINO_USER_AGENT environment variable not set

[PaulStoffregen]

Describe the problem

Latest IDE nightly builds are not setting the ARDUINO_USER_AGENT environment variable when running tools.

To reproduce

Using Linux x86-64:

1: File - Preferences, add Teensy URL https://www.pjrc.com/teensy/package_teensy_index.json
2: Boards Manager, Install Teensy 0.59.4
3: Copy this modified teensy_size tool to ~/.arduino15/packages/teensy/tools/teensy-tools/0.59.4/
4: Click Verify and look for "ARDUINO_USER_AGENT = " in the output panel.

Alternately, edit the source code for any tool to print the ARDUINO_USER_AGENT environment variable. This copy of teensy_size merely has these lines added:

      const char *ardua = getenv("ARDUINO_USER_AGENT");
      fprintf(stderr, "ARDUINO_USER_AGENT = %s\n", ardua);

Expected behavior

The ARDUINO_USER_AGENT environment variable is supposed to be set, according to the Platform Specification, under "Environment variables":

https://arduino.github.io/arduino-cli/0.35/platform-specification/#environment-variables

Arduino IDE 2.2.1 does it correctly:

Arduino IDE version

arduino-ide_nightly-20231227_Linux_64bit

Operating system

Linux

Operating system version

Ubuntu 22.04

Additional context

No response

Thank you for reporting it

Latest IDE nightly builds are not setting the ARDUINO_USER_AGENT environment variable

IDE2 has never set any environment variables. I see this is an issue in the CLI: arduino/arduino-cli#2499. I keep this issue open for visibility.

[PaulStoffregen]

I tested the new CLI 0.35.1 release just now. Can confirm it defines ARDUINO_USER_AGENT.

Will test IDE nightly builds to confirm here. Hopefully nightly builds have CLI 0.35.1 soon?

3: Copy this modified teensy_size tool to ~/.arduino15/packages/teensy/tools/teensy-tools/0.59.4/

@PaulStoffregen, can you provide a link to the modified tool for macOS (Intel)? I want to verify #2332.

• I downloaded the tool,
• copied it to the desired location (on macOS /Users/a.kitta/Library/Arduino15/packages/teensy/tools/teensy-tools/0.59.4),
• changed the permissions (chmod +x)

I got this error when compiling in IDE2:

fork/exec /Users/a.kitta/Library/Arduino15/packages/teensy/tools/teensy-tools/0.59.4/teensy_size: exec format error

Compilation error: fork/exec /Users/a.kitta/Library/Arduino15/packages/teensy/tools/teensy-tools/0.59.4/teensy_size: exec format error

Thank you!

Will build a MacOS copy in several hours. Right now I have a Windows test machine set up on my workbench. Need to first wrap up this work with Windows before I can put it away and set up my Mac.

Will build a MacOS copy in several hours.

You don't need to. Thank you! You've already helped a lot by checking the build from the PR (#2332 (comment)).

I've set up my Linux env and will go ahead with the already attached binary for Linux.

[PaulStoffregen]

I built the modified teensy_size for MacOS.

Final followup to confirm nightly build now has this issue fixed.
