Problem with mktex* generated files when running latex on GCP cloud run

[Norbert Preining]

Hi Karl,

thanks for looking into that.

> ls -l /tmp/foobar/fonts/tfm/lh/lh-t2a/larm1000.tfm # guesing it's there

-rw-r--r-- 1 worker users 3220 Jul 10 03:48 /tmp/foobar/fonts/tfm/lh/lh-t2a/larm1000.tfm

> kpsewhich -var-value TEXMFVAR

/tmp/foobar

> kpsewhich --debug=-1 larm1000.tfm

Here it is getting interesting, I give longer logs below, but I think
the core part is here:

*** on gcp cloud *****
kdebug:dir_links(/tmp/foobar/fonts/tfm/lh) => 2
kdebug:path element /tmp/foobar/fonts/tfm// => /tmp/foobar/fonts/tfm/ /tmp/foobar/fonts/tfm/lh/


*** when running docker image locally ***
kdebug:dir_links(/tmp/foobar/fonts/tfm/lh) => 1
kdebug:dir_links(/tmp/foobar/fonts/tfm/lh/lh-t2a) => 1
kdebug:dir_links(/tmp/foobar/fonts/tfm/lh/lh-t2a/larm1000.tfm) => -1
kdebug:path element /tmp/foobar/fonts/tfm// => /tmp/foobar/fonts/tfm/ /tmp/foobar/fonts/tfm/lh/ /tmp/foobar/fonts/tfm/lh/lh-t2a/


The gcp cloud run does not list the directory "lh-t2a" nowhere.



More complete log for both

Yes, it seems that kpathsea cannot find the file, while the file system
shows it as present.

Best regards
