Thread safety with multi thread

[benconda]

Hello,

I really like FrankenPHP approach, but I have an edge case and have some questions.

In my case, I use through PHP FFI a C library that is not thread safe. Didn't tested yet but I assume it won't work well with FrankenPHP due to multi threading.

Is there any solutions where we need more resilience or process isolation ? Or something that is planned to overcome this ?
Didn't find relevant information in existing discussions / issues.

Thank you,
and good job for making such a great things.

Requests are still processed on a single thread; so it might be fine. The only time you'd really run into issues is if you want to share data between threads.

Thank you for the answer.

To precise more, in my case it's a library that open documents, concurrent http request may access the same document. Because we can have some operation by document pages (extract page size, render a page as a picture, etc).

I think I will take some time to do a poc and see how it behave 👍

My goal is to provide a sample usage of a php lib I'm working on, using FrankenPHP for simplicity.

tl;dr: It's a pdfium library wrapper / binding in PHP, a C++ lib maintained by google and used in chromium for pdf visualisation.

Reading from a file in parallel should generally be fine, you might need to implement a lock for writing to the same file though depending on how the library handles this.
