* Freeing critical sections via atexit in system/alloc and system/io (#19062)Tail Wag Games2021-10-291-4/+4
| | | | | | | | | | | | | | | * adding new system module sysexitprocs and including system exit procedures when registering exit handlers defined in userland * fixing failing tests and adding initialization guard to handle cases where the module's global init logic isn't invoked first as is the case with some gc implementaions * js backend shouldn't try to invoke actual system exit procs * fixing formatting in sysexitprocs.nim * 256 was too much - my max number of plugins in my engine is 64 and I require two hooks per runtime it looks like with tls emulation turned off, so for my purposes 128 should be sufficient * so atExit should be enough here, can get rid of all the extra cruft I had added on top since I didn't realize atExit already provided a stack * done being cute - since newruntime prevents correct cpp codegen for object variants apparently and breaks tests if I try to use std/exitprocs, ddSysExitProc is just going into both modules. Since system doesn't include system/io, polluting system with it doesn't make sense either... at least it is only importc'd when it is required in either module and we don't have to have any weird when defined(nimOwnedEnabled) with a comment explaining why
* deinitializing locks at program exit (#19043)Tail Wag Games2021-10-251-24/+32
| | | | | | | | | | | | * deinitializing locks at program exit * deinitLock shouldn't be called for js backend I guess... * I suppose this is the best way to detect the ewruntime option * I guess I need these guards here too... * fixing merge conflict

* Make file descriptors from stdlib non-inheritable by default (#13201)alaviss2020-04-201-5/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * io: make file descriptors non-inheritable by default This prevents file descriptors/handles leakage to child processes that might cause issues like running out of file descriptors, or potential security issues like leaking a file descriptor to a restricted file. While this breaks backward compatibility, I'm rather certain that not many programs (if any) actually make use of this implementation detail. A new API `setInheritable` is provided for the few that actually want to use this functionality. * io: disable inheritance at file creation time for supported platforms Some platforms provide extension to fopen-family of functions to allow for disabling descriptor inheritance atomically during File creation. This guards against possible leaks when a child process is spawned before we managed to disable the file descriptor inheritance (ie. in a multi-threaded program). * net, nativesockets: make sockets non inheritable by default With this commit, sockets will no longer leak to child processes when you don't want it to. Should solves a lot of "address in use" that might occur when your server has just restarted. All APIs that create sockets in these modules now expose a `inheritable` flag that allow users to toggle inheritance for the resulting sockets. An implementation of `setInheritance()` is also provided for SocketHandle. While atomically disabling inheritance at creation time is supported on Windows, it's only implemented by native winsock2, which is too much for now. This support can be implemented in a future patch. * posix: add F_DUPFD_CLOEXEC This command duplicates file descriptor with close-on-exec flag set. Defined in POSIX.1-2008. * ioselectors_kqueue: don't leak file descriptors File descriptors internally used by ioselectors on BSD/OSX are now shielded from leakage. * posix: add O_CLOEXEC This flag allows file descriptors to be open() with close-on-exec flag set atomically. This flag is specified in POSIX.1-2008 * tfdleak: test for selectors leakage Also simplified the test by using handle-type agnostic APIs to test for validity. * ioselectors_epoll: mark all fd created close-on-exec File descriptors from ioselectors should no longer leaks on Linux. * tfdleak: don't check for selector leakage on Windows The getFd proc for ioselectors_select returns a hardcoded -1 * io: add NoInheritFlag at compile time * io: add support for ioctl-based close-on-exec This allows for the flag to be set/unset in one syscall. While the performance gains might be negliable, we have one less failure point to deal with. * tfdleak: add a test for setInheritable * stdlib: add nimInheritHandles to restore old behaviors * memfiles: make file handle not inheritable by default for posix * io: setInheritable now operates on OS file handle On Windows, the native handle is the only thing that's inheritable, thus we can assume that users of this function will already have the handle available to them. This also allows users to pass down file descriptors from memfiles on Windows with ease, should that be desired. With this, nativesockets.setInheritable can be made much simpler. * changelog: clarify * nativesockets: document setInheritable return value * posix_utils: atomically disable fd inheritance for mkstemp
