--- Comment #8 from Zoltan Herczeg <hzmes...@freemail.hu> --- > Then mmap it once writable to edit the JIT code; when you're finished, mmap > it execable instead. Here comes the first question: PCRE-JIT support multithreading, where one thread can compile a new JIT code while another thread executes a compiled JIT code. If I cannot map it as both writable and executable, how can I handle it? If it is not possible, I need to allocate 4K aligned spaces for all compiled patterns, which wastes memory, but writing and executing can be separated. And that does not even need any temporary files. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
