Hi all,

I notice the following:

    $ darcs --version
    2.5 (release)

    $ darcs show repo
              Type: darcs
            Format: hashed, darcs-2
              Root: /home/lele/wip/aem/gam
          Pristine: HashedPristine
             Cache: thisrepo:/home/lele/wip/aem/gam, cache:/home/lele/.darcs/cache
    Default Remote: http://darcs.arstecnica.it/our/gam
       Num Patches: 1895

    $ darcs put /tmp/prova-gam
    Note: if you want to change the default remote repository to
    /tmp/prova-gam,
    quit now and issue the same command with the --set-default flag.
    darcs: <stdin>: hIsTerminalDevice: illegal operation (handle is closed)
    Apply failed!

    $ cd /tmp

    $ tree -d prova-gam
    prova-gam
    `-- _darcs
        |-- inventories
        |-- patches
        |-- prefs
        `-- pristine.hashed

    5 directories

    $ ls prova-gam/_darcs/patches/ | wc -l
    1896

So, it seems it effectively copied all the patches. Just to be sure, I
check that "darcs get" works:
    
    $ darcs get $OLDPWD test-gam
    Note: if you want to change the default remote repository to
    /home/lele/wip/aem/gam,
    quit now and issue the same command with the --set-default flag.
    Copying patches, to get lazy repository hit ctrl-C...
    Finished getting.

Ok.

Now with darcs 2.4:

    $ cd -

    $ darcs-2.4 --version
    2.4 (release)

    $ darcs-2.4 put /tmp/prova-gam-2.4

Yup, it works!

Hope this helps,
ciao&thanks, lele.

Ouch, even "push" fails in the same way:

    $ darcs init --repodir /tmp/push-test

    $ darcs push -a /tmp/push-test
    Note: if you want to change the default remote repository to
    /tmp/push-test,
    quit now and issue the same command with the --set-default flag.
    darcs: <stdin>: hIsTerminalDevice: illegal operation (handle is closed)
    Apply failed!                                               

Alarmed, I tried with a few other repositories of mine, but none
exhibited the problem. Phew!

This tampers the ability to upload *this* repository from the outside
and that's marginal enough... but what can be going wrong with it?

ciao, lele.

This is probably a duplicate of issue1980.

I'm going to *assume* it's a duplicate for now purely on the basis of 
similar error messages.
