What has changed in skalibs

in 2.3.1.3

• Bugfix release, no functional changes.

in 2.3.1.2

• The child_spawn* family of functions now resets all signals to their default values when spawning a program on systems with posix_spawn(). This should not change anything - it's just paranoia.
• Minor bugfixes.

in 2.3.1.1

• Bugfix release, no functional changes.

in 2.3.1.0

• wait_status() now returns 256 + signal number when WIFSIGNALED().
• new macro wait_estatus() to get WIFSIGNALED information in an exit code.
• new functions in djbunix.h: hiercopy(), hiercopy_tmp()

in 2.3.0.1

• wait_status() now returns 256 (instead of 126) when WIFSIGNALED().

in 2.3.0.0

• buffer_getvall and buffer_putvall have a different interface. (And now work.)
• buffer_read and buffer_write are now deprecated.
• various siovec additions, such as siovec_trunc

in 2.2.1.0

• unixconnection added.
• sig_name and sig_number added.

in 2.2.0.0

• TAI64 and TAI64N conversion functions revisited. API slightly changed, made more consistent.

in 2.1.0.0

• unixmessage_drop added, part of unixmessage/skaclient hardening against fd leakage
• unixmessage_sender_flush return code aligned with the convention in the rest of skalibs
• unixmessage_sender_flush now handles short writes
• skaclient_start(_async) prototype changed: now takes an option argument

in 2.0.0.0

• The packaging system has completely changed.
• Programs should now link with -lskarnet followed by the appropriate sysdeps links.
• No compatibility is ensured. Most APIs haven't changed, but no guarantee is offered.
• The most important change is probably the disparition of struct tai and struct taia, replaced with the tai_t and tain_t types. Attosecond precision has been removed - processor speed is almost capped now, and it looks like nanosecond precision will be enough for the foreseeable future.
• Buffer implementation has changed, and some interfaces too, mainly the buffer_flush and bufalloc_flush return code.
• skaclient, skalibs' client-server communication suite, has been entirely reimplemented: it's now using the new "unixmessage" set of primitives for easier fd-passing.
