Subject: [PATCH 14/14] MEDIUM: systemd-wrapper: support multiple executable
versions and names
Having to use a hard-coded "haproxy" executable name next to the systemd
wrapper is not always convenient, as it's sometimes desirable to run with
multiple versions in parallel.
Thus this patch performs a minor change to the wrapper : if the name ends
with "-systemd-wrapper", then it trims that part off and what remains
becomes the target haproxy executable. That makes it easy to have for
example :
haproxy-1.5.4-systemd-wrapper haproxy-1.5.4
haproxy-1.5.3-systemd-wrapper haproxy-1.5.3
and so on, in a same directory.
This patch also fixes a rare bug caused by readlink() not adding the
trailing zero and leaving possible existing contents, including possibly
a randomly placed "/" which would make it unable to locate the correct
binary. This case is not totally unlikely as I got a \177 a few times
at the end of the executable names, so I could have got a '/' as well.
Back-porting to 1.5 is desirable.
(cherry picked from commit ceaf2aec1ec1612da461c61798e944693144bee9)
