Update Boards version number to a different version and then change back may not work.

[KurtE]

Describe the problem

Suppose I have the Teensy board types installed, like 1.58.1, and I did a few builds, and then decide I wish to try something out on the current beta build 0.59.2. Run a test or two, then decide to update back to 1.58.1

And now the builds fail.

The problem is that the tool Teensy.exe was running when I installed or reinstalled the different versions.

To reproduce

Update from to 0.59.2 The output window shows:

Tool teensy:teensy-compile@11.3.1 already installed

Now I convert back to 1.58.1

I then try building the same sketch over again and see:

So I looked in the tools directory and all that was init was:

My first thoughts were, that my Anti-virus decided to quarantine the new files for some reason. So it took several minutes for me to figure out how to see what was currently quarantined and the list was empty.

So I am now believe what happened is that when it installed the new version of tools, it tried to remove the other version, and failed to remove open executable. And then when I asked it to reinstall that version, it saw the directory existed and assumed everything was fine.

Expected behavior

One or both of:
a) when it tried to remove the previous version and failed, it should give me some type of warning and better yet let me know that the app Teensy is running, and give me a chance to do a retry.

b) When it detects that the tools directory existed, do a sanity check, like the package contained N object but the current one only has 1 in it...

Arduino IDE version

2.1.0

Operating system

Windows

Operating system version

11

Additional context

I did a quick search and did not find anything.

I resolved it this time, but closing the teesy.exe application, and change versions twice again and this time it removed the old version and the whole tools directory.

@PaulStoffregen - not sure anything we can do for this on the Teensy Side/

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

[PaulStoffregen]

Pretty sure the fundamental issue is Teensy tools continue running, but Arduino CLI & IDE have an implicit expectation that tools completely exit.

Later when you try to update or uninstall the Teensy tools, Arduino CLI (or IDE) isn't able to deal with the fact the a tool is still running in the background, which causes the operating system to disallow deleting its executable file.

I don't see any easy solution. Normal tools don't have any defined protocol like pluggable discovery and monitor do, to tell the tool running in the background to quit. But even without this, I would imagine the Arduino software could be much better about checking for errors while deleting files.

Trying to repro observe this - with regard to Teensy_Ports and Serialmonitor active the version change similar to KurtE was noted when Teensy.exe was CLOSED. 1.58.1 was installed then updated to Beta 0.59.2. That folder created holding only Teensy.exe it seems. SO could not complete a build until the tools were copied from a IDE 1.8.19 folder.

Went back to 1.58.1 and the 0.59.2 folder was emptied but not removed. I cannot remove this directory manually either from file explorer of a cmdline PowerShell window as it is marked 'in use' - though EMPTY?

Trying again to upgrade from updated release 1.58.1 to beta 0.59.2 I got this:
