FontValidator exits with 1 (instead of zero) on a successful run

[erniemarch2]

When called from the command line (python script looping through several fonts in a folder),
font validator processes the first item and returns non-zero exit status of 1, causing
the python script to stop and not process the remaining items.

You are aware that fontval itself takes multiple font arguments? As in '... -file font1.ttf -file font2.ttf ...'?

Also, if you really want to not stop on fatal errors, you do

'find /dir -type f -name "*.ttf" -exec FontValidator ... {} ;' ?

This is what I do for testing all 3500 fonts that fedora ships.

Yes, but we can't do that because the process we're running needs to call other tools on the same font.

Also, if you really want to not stop on fatal errors, you do
'find /dir -type f -name "*.ttf" -exec FontValidator ... {} ;' ?

I appreciate the suggestion, but we're not running FontValidator from the command-line, we're calling it from a Python subprocess.

The exit status from mono when FontValidator is running outside of it seems to be correct, and it looks like a mono bug for the process of bundling mono with FontValidator. I'll file a bug upstream.

@HinTak thank you 🙇

I did file it upstream, mono/mono#13629 , just forgotten to come back to mention it here. Feel free to ping upstream...
