Comment (by knarf):
Replying to [comment:9 rhaas]:
> When you say "tells Cactus that thorn is ready" do you mean "cactus
thornlib or make.checked target depends on this so that thornlib or
make.checked is updated triggering dependent thorns to rebuild
themselves"?
Yes.
> For 'available' it says "is created and/or updated whenever detection is
run and something was detected." does that mean "available" is not touched
if detection is run and nothing was detected (this would seem to be in
direct contradiction of "tells the make system whether build.sh needs to
run, i.e., whether after detection a build is necessary. ")? Which script
creates/touches 'available'? Only detect.sh or sometimes also build.sh?
Good questions. I think I might have gotten something wrong.
'available' will get set both by detect.sh when something was detected,
and by build.sh if it was build. Both will update the time stamp. However,
this leaves us with the problem that we both want to use it to see if
detect.sh found something, but also for preserving the last built date (if
build). We cannot do both, as detect.sh should remove the file in case
nothing is detected to indicate that. Do we need yet another indicator
('done', 'last_build', 'syslib_detected')?
