[mcclim-devel] Copying text to clipboard loops displaying messages to Konsole
When I copy some text with Shift-left-click from the CLIM Listener for later copying somewhere else, I get an infinite loop that displays messages (all identical) like this to the KDE Konsole from which I have started the Listener: #<CLIM-CLX::CLX-SELECTION-REQUEST-EVENT {5850A54D}> is an instance of type CLX-SELECTION-REQUEST-EVENT it has the following slots: TIMESTAMP: 5010524 SHEET: #<CLIM:INTERACTOR-PANE CLIM-LISTENER::INTERACTOR {58B8A0CD}> REGION: <unbound> SELECTION: :PRIMARY REQUESTOR: #<XLIB:WINDOW :0 31457298> TARGET: :COMPOUND_TEXT PROPERTY: :_QT_SELECTION If I later paste with Shift-middle-click the clipboard selection to another Konsole pane, I get a garbled string similar to that described here: http://common-lisp.net/pipermail/mcclim-devel/2004-December/002731.html I have to quit the Listener in order to stop the infinite loop. I use CMUCL Snapshot 2005-02 with the latest McCLIM CVS sources under Slackware Linux 10.0, with a 2.6.10 kernel. Paolo -- Lisp Propulsion Laboratory log - http://www.paoloamoroso.it/log

With the latest McCLIM CVS sources, I can correctly paste text from the CLIM Listener to a Konsole. But I get an endless stream of identical messages like this in the Konsole from which I start McCLIM: <CLIM-CLX::CLX-SELECTION-REQUEST-EVENT {59E5A935}> is an instance of type CLX-SELECTION-REQUEST-EVENT it has the following slots: TIMESTAMP: 3664352 SHEET: #<CLIM:INTERACTOR-PANE CLIM-LISTENER::INTERACTOR {59EC4F6D}> REGION: <unbound> SELECTION: :PRIMARY REQUESTOR: #<XLIB:WINDOW :0 31457298> TARGET: :COMPOUND_TEXT PROPERTY: :_QT_SELECTION ;; clim-clx::send-selection - Requested target COMPOUND_TEXT, sent COMPOUND_TEXT to property _QT_SELECTION.

Well, maybe, but the backtrace you provided indicates that multithreading was running. Could you turn it off completely, please? I'd like to see the results when there is precisely one cmucl thread.

I'm not sure there's an easy way to disable threading in CMUCL. It might involve finding where :clim-mp gets pushed onto *features* and preventing that from happening, then recompiling McCLIM from scratch. On Mon, 07 Mar 2005 17:46:15 +0000, Christophe Rhodes <csr21@cam.ac.uk> wrote:

I see. Christophe was probably talking about disabling threading in McCLIM, but I misunderstood and thought he referred to CMUCL's multithreading. Paolo -- Lisp Propulsion Laboratory log - http://www.paoloamoroso.it/log

To do these tests I start CMUCL with CLX, load the CLIM Listener with: (asdf:operate 'asdf:load-op :mcclim) and start it with: (clim-listener:run-listener) Just before starting the Listener, the state of CMUCL multithreading is as follows: * (mp:show-processes) -> #<Process Initial {58B8442D}> "Run" ACTIVE NIL * Is multithreading running at this stage?

I replaced it with (open-display "localhost") and run the test, i.e. started the program, left clicked in its window, and midlle-clicked in a Konsole. The pasted string is: Hello, World (from the CLX clipboard)!

... but "KLIPPER", probably some bizarre KDE thing, is now getting in the way. OK, but in this test you're not getting any length-errors. Hmm. So I might not be seeing the problems you're seeing because I'm not running a KDE environment; I'm simply testing in the terminals you're saying you see problems with. If there are desktop-specific clipboard daemons, there is quite reasonably MORE PAIN to be experienced. I don't really know what to suggest; I'd probably ask the developers of whatever desktop environment you're using about known interoperability issues with clipboard handling, and see if they act shy and bashful. I claim that clipboard.lisp is ICCCM-compliant code, but I've been wrong before -- specifically, I've been wrong when I reported a bug in gdk about it, so it's possible there are bugs lurking. There is C code referenced from the lisp file which might be of assistance when talking to C-based developers; asking them why the C code produces an endless loop might prompt a response.

According to the KDE documentation: Klipper is the KDE clipboard utility. It stores clipboard history, and allows you to link clipboard contents to application actions. If I disable it and try pasting text from the CLIM Listener to a Konsole, the text is pasted correctly and I only get these 2 messages (no longer an infinite loop): #<CLIM-CLX::CLX-SELECTION-REQUEST-EVENT {598A0ED5}> is an instance of type CLX-SELECTION-REQUEST-EVENT it has the following slots: TIMESTAMP: 4226073 SHEET: #<CLIM:INTERACTOR-PANE CLIM-LISTENER::INTERACTOR {59DED39D}> REGION: <unbound> SELECTION: :PRIMARY REQUESTOR: #<XLIB:WINDOW :0 33554937> TARGET: :TARGETS PROPERTY: :_QT_SELECTION ;; Warning, unhandled type "TARGETS".

So, it looks like this is a KDE thing. No big deal, once I am aware of this.
I don't really know what to suggest; I'd probably ask the developers
I don't use Klipper much anyway, so I'll probably keep it disabled. Thanks, Paolo -- Lisp Propulsion Laboratory log - http://www.paoloamoroso.it/log

Hi, Paolo. Could you try pasting with Klipper enabled and with the attached patch? (I spent some time with the ICCCM, and some more time debugging my use of CLX, but I /think/ the attached now behaves at least partly correctly). [ Andy, if you're listening in: there have been several issues involved here: Klipper is entitled per ICCCM to assume that we implement the :TARGETS and :TIMESTAMP selection targets. More to follow on the CLX lists. ] Cheers, Christophe

OK. So I think the clipboard-handling code is now correct, and to make the user experience better one would simply not print the debugging cruft to *trace-output*. Anyone care to review the latest patch I sent? Cheers, Christophe

Right. Reading around the web indicates that Klipper is not completely alone in its strategy of polling the selection owner for the timestamp of its selection ownership to see if anything has changed. I've therefore committed more-or-less what I sent, along with something which disables logging these events to the console. I hope that I haven't broken anything in the process. In the meantime, here are some things which don't currently work (they didn't before the patch either): * pasting high-latin characters into the listener. (pasting them out from the listener is fine). This is possibly because the paste is implemented in terms of generating key-press-events -- is there a mismatch somewhere between what is a key press and what is a character? * selecting user-typed input to the listener. I think this is because such user-typed input has no associated output records; getting this right might be tricky. * (relatedly) pasting from Climacs doesn't work as expected, because Space and Tab characters in the buffer don't get associated output records. Presumably what needs to happen here is that Climacs needs to implement its own methods for these protocol functions. Cheers, Christophe

Text paste seems to be working fine with Klipper now. Paolo -- Lisp Propulsion Laboratory log - http://www.paoloamoroso.it/log
