Freetype font management thread-safety
as-ascii opened this issue · comments
First of all, as always, thanks for your work on the project
It seems that there is a thread-safety problem related with freetype library. I think it would be better to introduce a mutex in PoDoFo than require a mutex around PoDoFo calls. Please find Thread-sanitizer error with backtrace below. DocWire namespace is just the parent project https://github.com/docwire/docwire using PoDoFo, you can just skip this part of backtrace.

PoDoFo is a manipulation (read/edit) library and is general is not thread safe. It is neither designed to be read-only thread safe as many things are lazily loaded and there are no locks to synchronize these initializations, in 0.9.x as well (only few global stuff is accessibile as singletons and implicitly guarded by locks). I have no imminent plans to add some level of thread safety but I'm imaging we could add a whole document/per-page eagerly load functions so subsequent read operations are thread safe. Edit and deallocation operations shall still be affine to the creation thread. It's not in my top priority list as I'm still continuing slowly (but steadily) the API review. Feel free to elaborate and add your considerations to this issue.
