There are multiple problems with cfengine3-make-syntax-cache:
1. call-process-shell-command changed in trunk; simply replace it with
process-file.
2. it doesn't always return a `syntax' value
3. cf-promises doesn't have -s option in Centos 6.5 (cfengine 3.3)
HTH,
Leo

Thanks for catching this, I had not noticed it sooner. Please see the
patch below; does it work for you? If so I will commit and close the
bug.
LL> 3. cf-promises doesn't have -s option in Centos 6.5 (cfengine 3.3)
I think that's all right, we will default to the fallback syntax. The
`-s' option was added after 3.3 but IMO the fallback syntax is good
enough for all 3.x work.
(Unfortunately the Red Hat ecosystem has no CFEngine package maintainers
so to get the latest you have to install from the official CFEngine
package repo as directed by their website.)
Thanks
Ted

cfengine3-make-syntax-cache may still return a regexp and it won't fall
back on cfengine3-fallback-syntax when `cf-promises -s json' fails; how
about something along these lines?

Agreed. Sad to see this and the cf community seems not very active. BTW,
do you know if CF is still part of GNU? I only see version 2 on GNU¹.

I like your patch better :)
Can you commit or let me know and I will? It will close this ticket, I
hope.

CFEngine 3 was a rewrite of version 2. It's still under the GPL but no
longer part of the GNU project AFAIK. IMO it's quite good (the latest
release is 3.6.2) and it's actively maintained by CFEngine Inc, but the
proprietary non-free extensions in their Enterprise version and the
corporate ownership of the codebase make it unlikely it can be part of
the GNU project in this incarnation.

OK, I am committing the patch (it's been 30 minutes, it hurts when it is
this slow). I have discovered a few other issues and fixed them along
the way. If you have time could you test it to make sure I don't break
something else.

I'll take your word for it ;) Thanks for the info.

It's good. I'll keep testing it; marking the bug done.
Thanks for the help!
