When using emacs from the terminal, pasting a largish (~>600K) amount
of text via the terminals paste functions results in an incomplete
paste of the text.

I've tried this in gnome-terminal, konsole, and xterm.

To recreate:

1) Visit http://cnn.com
2) View Source, and copy it
3) Open a terminal and start emacs (emacs -nw --no-splash)
4) Paste via the terminal's paste function (not emacs-specific *yank*)

The result (in my case) is the last 50 or so lines of the HTML.

Following the same procedure in vim/joe/nano/pico, and even echo and
cat result in the HTML in its entirety.

I've tried this in GNU Emacs 22.1.1, GNU Emacs 23.0.60.1, and GNU Emacs 21.3.1.

I've tried this on Ubuntu 8.04 and RHEL3 WS (remotely).

I popped into #emacs, and someone there was nice enough to verify that
they saw the same symptom using non-html text.

This is *not* a problem in the GUI versions of emacs.


Thanks so much.

All,

I would like to post a more easily tested scenario for this bug.
Additionally, I have tested it on:

version  23.1.90.1 on OS X
version 23.1.50.1 on Ubuntu 10.04 (emacs-snapshot)

I wrote a script that prints out 1024 lines of output.  It looks like this:

LINE 0
LINE 1
LINE 2
...
LINE 1023

If you copy this 1024 line output, and paste it into emacs running in
a terminal (not the GUI), you will not see all 1024 lines.  In fact,
toward the end, you will get random garbage.  For example, my last
attempt printed:

LINE 464
LINE 465
LINE 466
LIN6
LINE 507
LINE 508
LINE 629
LINE 630
LINE 631E 67
L 8

This does not happen in ANY other editor I have tried that uses the
terminal.  But if course, I don't really want to use any other editor,
which is why I am pinging this report with additional test info. ;)
The test takes seconds to run, and I would sure appreciate some
movement on this bug.

Thanks!
James

These are ancient pretests for what became the 23.2 release.
These should not be used any more - use 23.2 instead.

(Your issue may well still be present in 23.2, I did not test.)

    ^ byte 4096

Apparently the pty buffer of your system has a size of 4096 bytes.  If
the terminal keeps stuffing more bytes into the master side of the pty
that buffer overflows and bytes are dropped until the process at the
other side of the pty had a chance to read some.  This is unlikely to be
fixable inside Emacs.

Andreas,

If this were the case, then why would other editors on the same
systems in the same terminal emulators not exhibit this behavior?  All
other tested editors (vi, vim, nano, etc) pasted the entire buffer.

Thanks!

Thanks Glenn, I'll build 23.2 up on a few systems here and post back.

This sounds like http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6571

(Fixed in trunk.)

Not really, see http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6571.  A 
candidate for emacs 23 backport perhaps?

Johan, Jan, you were absolutely right!

The head works fine, and this bug can be marked as a duplicate of the
newer bug 6571.  I would love to see a backport of this, but am happy
to build my own for now :)

Thanks to everyone for the helpful feedback!

Indeed, please backport it to emacs-23.
