* Separate and expose ancil_recv_fd/ancil_send_fdLaurent Bercot2020-10-267-7/+7
| | | | | | | 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.
* Change new function names to openc_*; update deps.makLaurent Bercot2020-10-2613-15/+15

* Fix alloc_realloc UBLaurent Bercot2020-04-293-4/+4
| | | | | | | | | | | | | 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.
* bugfix: sigprocmask invocation on non-signalfd systemsLaurent Bercot2020-04-041-1/+1

* 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.

* Big wallclock/stopwatch refactor. It was long overdue.Laurent Bercot2019-09-039-112/+103
| | | | | | | | | | | | | * --enable-clock and --enable-monotonic are gone * tain_sysclock() has been renamed tain_wallclock_read() * tain_wallclock_read() reads from CLOCK_REALTIME (or gettimeofday()) * tain_clockmon[_init]() have been renamed to tain_stopwatch_[read|init]() and now accept a monotonic clock name as an extra argument * tain_now() points to the system (wall) clock by default * tain_now_set_[stopwatch|wallclock]() can be used to switch Now to make a pass on all skarnet.org programs and add a tain_now_set_stopwatch() call everywhere needed... >.>

* Add skalibs/posixishard.hLaurent Bercot2019-02-197-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This will break things. It's a known issue. Patches to other packages will come later, to adapt them to the new API. To work around brokenness, there needs to be *two* different headers: 1. one to be used before including system headers, that maximizes visibility by enabling system-dependent feature test macros (that will be tested by system headers) 2. one to be used after including system headers, that performs preprocessor tests and defines. skalibs/nonposix.h is the first one. Previously, there was no second one, and the tests were scattered all over. There was a strnlen declaration in skalibs/posixplz.h (which serves a totally different function: declaring things that should be in POSIX, but *are not*, i.e. working around problems in the standard, instead of problems in systems failing to respect the standard), a build-time sysdep for error.h, #defines for MSG_NOSIGNAL, etc. etc. skalibs/posixishard.h now is the second one, and centralizes all the tests. As a result, the eproto sysdep is unnecessary and has been removed. skalibs/error.h is now a static header, it is not built anymore.

* fix null-pointer behavior in fmt and fmtlist functionsJohn Regan2019-02-051-12/+11
| | | | | | This fixes a segfault when a user calls uint320_fmt(NULL,...), and makes the fmtlist functions return the correct number of characters when called with NULL.
