Document and fail fast if tmp directory is noexec #252

Open melissalinkert opened 5 months ago

melissalinkert commented 5 months ago

Updates readme to reference the known noexec issue, and tries to detect and fail conversion quickly if that is the case. The check is very heavy-handed, as it should always fail if java.io.tmpdir is noexec - independent of the input format or conversion options. We could make that more lenient if any strong opinions.

Two quick thoughts:

if possible, making this a flag might be worth the visibility and usability if this is going to become a more frequent issue
(possibly for upstream) I could also see this as a (personal) cache-dir scenario rather than temp-dir. If so, one could conceivably keep the files around until the next upgrade to speed up start up.

As discussed earlier today, the next steps here are:

keep the exception by default, but add an option to warn instead
make the readme changes a separate section (so we can link to it), and explain the issue a little more
delete the "check" file right away instead of on exit
include in a 0.10.0 (minor, not patch) release and make sure release notes flag this as a potentially breaking change

All except the actual release should be covered by 9dca8a9, cc2ec93, and 862e4ac.
