What has changed in s6
in 2.9.1.0
- The execline
dependency is now optional, and can be disabled via the --disable-execline
option to configure. Functionality that depends on execline in s6 binaries is
disabled when execline support is disabled.
- A new '?' directive has been added to s6-log,
it declares a processor command line that is spawned with the /bin/sh
interpreter.
in 2.9.0.1
- skalibs
dependency bumped to 2.9.1.0.
- execline
dependency bumped to 2.5.3.0.
in 2.9.0.0
- skalibs
dependency bumped to 2.9.0.0.
- execline
dependency bumped to 2.5.2.0.
- All the s6-fdholder-*c binaries have been
removed.
in 2.8.0.1
- skalibs
dependency bumped to 2.8.1.0.
in 2.8.0.0
- skalibs
dependency bumped to 2.8.0.0.
- execline
dependency bumped to 2.5.1.0.
- New -d notif option to s6-log.
- New default for the -l linelimit option to s6-log:
8192 bytes.
- In the accessrules library, checking against uid/gid
now checks the uid/self key if the client and the server have the same uid, and
the gid/self key if the client and the server have the same gid.
- Everything now builds as PIC by default no matter
the toolchain's settings. Use the --disable-all-pic configure
option to build executables and static libraries as non-PIC.
- This is a major version release of s6. It is recommended to first stop
all your s6 services, then upgrade, then immediately restart your
supervision tree, then start your services again. Failure to do so
*will* cause issues if you're relying on s6-ftrigrd notifications
(which is the case, for instance, with services managed by
s6-rc).
in 2.7.2.2
in 2.7.2.1
in 2.7.2.0
- Optional nsss support added.
- skalibs
dependency bumped to 2.7.0.0.
- execline
dependency bumped to 2.5.0.1.
- -B option added to
s6-ipcserver-socketbinder.
- -d notif option added to
s6-svscan.
- New optional ./down-signal file in a
service directory, to tell
s6-supervise to use another signal than
SIGTERM when bringing the service down.
- New -r option added to s6-svc, to
restart the service via the signal defined in ./down-signal.
in 2.7.1.1
in 2.7.1.0
in 2.7.0.0
- skalibs dependency bumped to 2.6.3.0.
- s6lockd and
s6-ftrigrd now use the new
textclient API and ABI from skalibs, instead of the
more generic skaclient. This is cleaner, faster code.
(s6-fdholderd still uses
skaclient, since its point is to transmit file descriptors,
which textclient does not support.)
in 2.6.2.0
- skalibs dependency bumped to 2.6.2.0.
- execline dependency bumped to 2.3.0.4.
- New s6_fdholder functions:
s6_fdholder_start(), s6_fdholder_end().

in order to fix a race condition in s6-rc.

in 2.5.1.0
- skalibs dependency bumped to 2.5.1.0.
- execline dependency bumped to 2.3.0.1.
- s6-ftrig-listen1 prints the last event
it received to stdout.

service directory and allows
s6-svc -d to send a SIGKILL after a timeout if the
process is still not dead after the initial SIGTERM and SIGCONT.
in 2.5.0.0
- skalibs dependency bumped to 2.5.0.0.
- execline dependency bumped to 2.3.0.0.
- Services can now report permanent failure by having ./finish
exit 125.

s6-svlisten and
s6-svlisten1 now exit 99
when they time out. They exit n when there are n
services reporting permanent failure.

- execline dependency bumped to 2.2.0.0.
- s6-ipcserver-socketbinder
can now create datagram sockets.

- The internals of s6-supervise have
changed; the supervise/status file ABI has changed and is not
compatible with the daemontools/runit supervise/status files
anymore. (This should not impact anything.)
- s6-supervise features a
configurable timeout for ./finish scripts, via the
./timeout-finish file.
- s6-svwait,
s6-svlisten1 and
s6-svlisten can now wait for a 'D'
