* Get rid of webipc.h and DJBUNIX_FLAG_*Laurent Bercot2020-12-0929-141/+139
| | | | | | | | | | | | | | Decent semantic header separation is hard. It's always an ongoing process. Here socket.h always included webipc.h for listen(), and webipc.h always included djbunix.h for socket_internal() and socketpair_internal(). That's ugh. Just move all the socket stuff into one socket header. Of course, djbunix.h is still needed most of the time for fd_close() and other operations on fds, but those are generic anyway. Also, O_CLOEXEC exists everywhere now, so we can use it as well as O_NONBLOCK instead of redefining the flags in djbunix.h.

* Revamp lock primitives; prepare for 2.10.0.0 instead of 2.9.4.0Laurent Bercot2020-11-2912-191/+74
| | | | | | | | | | | flock() doesn't have a way to test for a lock without taking it. lockf() doesn't have shared locks. The only way to have both is fcntl(). So I rewrote all the locking stuff around fcntl(), and used the opportunity to change the interface. The point of changing the interface is to stop having to bother with the old one, so to hell with compatibility, let's just do a major bump.

* Complete revamp of the pathexec functionsLaurent Bercot2020-11-2451-181/+392
| | | | | | | | | | | | | | | | | - pathexec_run is now called exec_ae a for provided file name (default: argv[0]) e for provided envp (default: environ) - pathexec is now called mexec. m for merge environment. Option letters are: a for provided file name (default: argv[0]) e for provided envp (default: environ) f for provided envp *and* length of the envp m for provided modif string plus its length (the length is always needed because the modifs are null-terminated) n for provided modif string, length *and* number of modifs - functions have a foo0 version for _exit(0) when argv[0] is null - functions have a xfoo version to die if the exec fails - and a xfoo0 - Compatibility #defines and #includes are there until the next major bump

* Separate and expose ancil_recv_fd/ancil_send_fdLaurent Bercot2020-10-2626-115/+157
| | | | | | | The goal is to make late channel creation easy, as opposed to textclient which always creates a new channel at start time. This commit also moves posixishard.h inclusions as late as possible.

* Fix alloc_realloc UBLaurent Bercot2020-04-294-5/+5
| | | | | | | | | | | | | void ** does not exist: the address of a generic pointer is not properly defined (different pointer types may have different representations). So, alloc_realloc cannot exist as is without UB. Fortunately, it's not supposed to be used in the skalibs programming style, and skalibs itself only uses it in two places (stralloc_ready_tuned and stralloc_shrink) where the pointer is a char *. So we just fix the UB by making alloc_realloc() take a char **, and it's only defined for that pointer type. Nothing to see here folks, nothing happened at all.

* Explicitly unblock signals when selfpiped without signalfdLaurent Bercot2020-02-262-3/+3
| | | | | | | | | | | | | | | | This is arguably a bugfix, since selfpipe without signalfd relies on signals being actually delivered, and a process may have inherited a nonempty sigprocmask. Also use SIG_BLOCK instead of SIG_SETMASK when using selfpipe_trapset() with signalfd, because we shouldn't unblock signals that may have previously been blocked. This is also arguably a bugfix. This commit is essential for using the version of s6-linux-init that blocks SIGINT before disablecad on kernels without signalfd. Without it, SIGINT never gets unblocked, so it's never delivered to s6-svscan.
