Bug#819341: [unison] Please build unison-fsmonitor

[Damian Lukowski]

Hi Frédéric,
Thank you for the proposed patch. I tried using it, and it appears 
that unison can't find the fsmonitor helper when it's named 
"unison-$(ABI)-fsmonitor". Instead it should be named 
"unison-fsmonitor-$(ABI)". See 



I think you need something like the attached patch (disclaimer: works 
on my machine, that's as much testing as I did).


thank you. I applied your patch on top, it works for me too.

Regards

Right. I've already uploaded unison-2.48 to NEW, let's settle on that
first. I will add the OCaml version number in the next OCaml transition.


Any news on the unison-fsmonitor helper to be compiled and bundled with 
the unison package ?

Right. I've already uploaded unison-2.48 to NEW, let's settle on that
first. I will add the OCaml version number in the next OCaml transition.

What would be important would be to include the OCaml version number
in the unison package name, since it has an effect on the behavior.

I had to put unison 2.48.4-1+b1 to hold on my Debian/unstable machines
in order to be able to sychronize with Debian/stable (buster) ones.

I am planning to change the packaging structure of Unison in Debian.

My current roadmap is:
- create a new source package unison-2.48
- make meta-unison provide unison and unison-gtk with symlinks to the
  binaries provided by unison-2.48
- let the "unison" source package disappear
- create a new source package unison-2.51 (or whatever is the latest
  version at the time)
- ...
- build unison-fsmonitor in unison-2.51

and be done with alternatives. This new packaging scheme makes more
sense IMHO and will ease co-installability of multiple versions of unison.


Cheers,

Dear maintainer,

Can you give an update when should we expect this in debian?
Either as a standolne package or part of the main one

Thank you for all your work.

Bug#819341: [unison] Please build unison-fsmonitor

[Liang Guo]

Package: unison
Version: 2.48.3-1
Severity: wishlist

In unison 2.48.3, a native fsmonitor is introduced, with the new fsmonitor, 
unison can impliment dropbox like sync on demand,following is quotad from 
upstream NEWS:

 * File system monitoring:
  + The file watcher now fails when unable to watch a directory,
rather than silently ignoring the issue.
  + File system monitoring: more robust communication with the
helper program (in socket mode, the unison server will still
work properly despite unexpected unison client
disconnections).
  + A bytecode version of unison-fsmonitor is now produced by
"make NATIVE=false"
  + Improved search for unison-fsmonitor

In Debian, unison is compile with NATIVE=true, so unison-fsmonitor is not 
compiled, would you compile unison with NATIVE=true to build unison-fsmonitor?

Thanks,
