Is this a breaking change?

my intention was that it doesnt break anything

for example which returns the path if it is already rooted and executable.

however, now that you got me thinking about it more, i think there are some edge cases wrt relative pathing.... i'll add code to handle.

ok i added the code above to root unrooted paths that contain relative pathing

in addition to checking the PATH, the which function also handles checking rooted paths

now the changes shouldnt be a breaking change. hard to imagine it would have practically broken anyone, but i'd rather cover edge cases to be on the safe side. Also now the changes align better with the default behavior of spawn.

i'll add unit tests tomorrow for the unrooted-relative-pathing cases

No, it's not a breaking change. It's additive. If you were passing in a fully qualified path, which will not changing anything. It will however add the ability to just pass in a tool name and it just works (as well as fixing some other issues and bugs).

@bryanmacfarlane Originally it was breaking, exec of a relative path would no longer work if we automatically which. That should be fixed now with @ericsciple's latest change

here is the test related to the bug fix.

toolrunner should which the tool before attempting to invoke. otherwise simple commands like npm --version fail on windows (ENOENT) because npm resolves to npm.cmd and node doesnt find it.

the naming of these script files is a little bit weird, but it's related to the conventions set forth by the existing test case scripts

i just copied one of the existing cmd files (but it had spaces in the path, and i didnt want that)

this script basically just echoes the args, e.g.

arg[0]: "hello" arg[1]: "world"

We have existing tests for exec.exec ("full path to executable"), these tests should cover the rest of the cases and fix this bug

The version of tool-cache was bumped, even though it seems that none of the files in packages/tool-cache was changed. Is this expected?

Should it mean to reflect that tool-cache is updated to use this new feature of exec, I'd expect files such as packages/tool-cache/src/tool-cache.ts to be modified:
