Justine Tunney	e11fa30791	Move zipos into runtime package ... This way complex runtime features (e.g. ftrace, symbol tables) can always yoink zipos support. This is important now that apelink.com automates embedding symbol tables for multiple cpus.	2023-08-11 23:14:02 -07:00
Justine Tunney	a808b3e738	Serialize ZipOS handle IO across threads	2023-02-23 06:55:10 -08:00
Justine Tunney	3265324e00	Don't relocate file descriptor memory ... This change fixes #496 where ASAN spotted a race condition that could happen in multithreaded programs, with more than OPEN_MAX descriptors when using ZipOS or Windows NT, which require tracking open file info and this change fixes that table so it never relocates, thus allowing us to continue to enjoy the benefits of avoiding locks while reading.	2022-09-09 16:54:28 -07:00
Justine Tunney	e466dd0553	Add torture test for zipos file descriptors ... This change hardens the code for opening /zip/ files using the system call interface. Thread safety and signal safety has been improved for file descriptors in general. We now document fixed addresses that are needed for low level allocations.	2022-06-15 16:29:49 -07:00
