134582 - unsupported X selection targets (supported by NS4)

Status: NEW

(Core :: DOM: Selection, defect)

Description

[Jamie Zawinski]

(I'm sure I picked the wrong component, but I don't
know which component means "X Front End".)

There are a number of selection targets that were
supported by previous versions of Navigator that
are now unsupported by Mozilla.

The most important one is FILE_NAME -- I have scripts
that want to grab the selection, and the URL or file that
it came from.  Mozilla no longer provides this info.

Here's a table comparing the two.

     Selection:           Netscape 4.78:            Mozilla 0.9.9:

These are correct:

     TEXT                 "PM"                      "PM"
     STRING               "PM"                      "PM"
     COMPOUND_TEXT        "PM"                      "PM"

These are wrong in Mozilla 0.9.9:

     LENGTH               2                         (none)
     TIMESTAMP            0xEF2CBCF1 (jan 1961??)   0
     FILE_NAME            "http://..."              (none)
     OWNER_OS             "Linux"                   (none)
     HOST_NAME            "grendel.jwz.org"         (none)
     PROCESS              20237 (pid)               (none)

     USER                 "jwz"                     (none)
     CLASS                "Netscape"                (none)
     NAME                 "netscape-navigator"      (none)
     CLIENT_WINDOW        0x0140050B (X window id)  (none)

And (for completeness) these are new to Mozilla:

     UTF8_STRING           (none)       "PM"  (as 16-bit characters)
     text/unicode          (none)       "PM"  (as 16-bit characters)
     text/html             (none)       "<font" ...etc...
                                              (as 16-bit characters)
     text/_moz_htmlcontext (none)       "<html" ...etc..
                                              (as 16-bit characters)
     text/_moz_htmlinfo    (none)       "0,0" (as 16-bit characters)


To test this stuff, go to an XEmacs *scratch* buffer and type
(x-get-selection-internal 'PRIMARY 'TARGETS) and so on, while
the selection is owned by another app.

This sounds like a blizzard bug.

I've never hacked on selection, that's all been pavlov.  I don't mind hanging on
to the bug but I'm not going to get to it any time soon.

See also bug 136776, wherein it is noted that the only *other* way to get the
browser to tell you what page it's looking at is *also* no longer implemented.

The bug assignee didn't login in Bugzilla in the last 7 months.
:enndeakin, could you have a look please?

I presume this is no longer relevant but let's just move over to a slightly more better component. I think it is referring to the data available in the selection buffer.
