From 07491df186d562d0efa6a7fca2b7f8d07dbd0652 Mon Sep 17 00:00:00 2001 From: Laurent Bercot Date: Mon, 23 Dec 2019 13:05:25 +0000 Subject: Make execline dependency optional This includes: - adding a configure option to disable execline support - duplicating el_semicolon() and el_getstrict() into the s6 library when execline is disabled at build time, making a compat shim and using it where needed (s6-svlisten, s6-ftrig-listen) - Creating alternatives for execlineb script spawning: * s6-log: '?' directive (done in the previous commit) * s6-notifyoncheck: require hardcoding the check in ./data/check * s6-ipcserver-access: no support for exec files, add a warning - Updating the relevant parts of the doc --enable-execline will remain the default, and whiners can choke on their tears. --- doc/s6-log.html | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'doc/s6-log.html') diff --git a/doc/s6-log.html b/doc/s6-log.html index 5cc4529..f042c70 100644 --- a/doc/s6-log.html +++ b/doc/s6-log.html @@ -234,14 +234,16 @@ padded with newlines so it is always statussize bytes long. 0 means an unpadded, unlimited status file.

  • !processor: registers execlineb -Pc processor as a processor for the next logdirs; -execlineb must be found in s6-log's PATH. +execlineb must be found in s6-log's PATH. This directive is only +supported if s6 has been built with execline support; otherwise, it yields a +syntax error at starting time. If processor is empty, no processor will be set for the next logdirs. By default, no processor is set.
  • ?processor: registers /bin/sh -c processor as a processor for the next logdirs. It is just like the ! directive, except that the processor string is interpreted by /bin/sh, not execlineb. It is useful -for people who have built s6 without execline support.
