Обсуждение: pasting into psql garbles text
I've noticed over a wide variety of operating systems that when you paste from an application into psql through a terminal (currently using the default gnome terminal in ubuntu), large pastes tend to get garbled with some of the input getting truncated. While working on functions, this is annoying in the extreme. Interestingly, the one platform that tends not to suffer from this is windows so I'm guessing this is a readline problem. Has anybody else noticed this? Is there a workaround? merlin

Even Ubuntu hides xterm away somewhere. Seriously, can you reproduce it in xterm? I can't, it's happily letting me paste in a 200k query with lines over 300 bytes long. What application are you pasting this text from? copy/paste in X requires the application you're pasting from to be surprisingly involved in the paste operation so perhaps it's behaving oddly. Also, what version of readline, X, gnome-terminal, and whatever application you're pasting from are you using? -- greg http://mit.edu/~gsstark/resume.pdf

However, pasting large functions or multi-line queries tends to mess up the readline history, so the next time I press arrow up, I'll often get garbled lines and lose the prompt. -- Leif Biberg Kristensen | Registered Linux User #338009 Me And My Database: http://solumslekt.org/blog/

Even Ubuntu hides xterm away somewhere. I confirmed that xterm does not exhibit the issue. So this is at least partially a terminal problem. However, xterm does not directly accept pastes from wine clipboard apparently. it only works if I copy it to gedit first, then into xterm. The _only_ terminal application that exhibits this behavior is psql. specifically, vim does not. > What application are you pasting this text from? copy/paste in X > requires the application you're pasting from to be surprisingly > involved in the paste operation so perhaps it's behaving oddly. It doesn't matter the source application...it borks regardless if I copy from Source insight/wine (my normal editor), gedit, or another gnome terminal. However, only psql exhibits this issue. For example, when I use the buffer editor (mine is set to vim), everything pastes in normally. > Also, what version of readline, X, gnome-terminal, and whatever > application you're pasting from are you using?

FWIW, I have noticed a limitation on how much can be pasted into psql
without freezing it (not more than a few hundred characters, for me).
It's not "garbled" ... psql just gets stuck and has to be SIGTERM'd.
However, there's enough stuff in the chain that I'm not sure
psql/readline is (solely) to blame --- I'm typically working through
a remote xterm over an ssh'd X11 connection.

Try pasting from an emacs or xterm? copying from xterm to gtk I can't seem to get working...I can copy _to_ xterm, but not from it (sigh). Anyways, that doesn't explain why the only terminal program that gets garbled is psql.

I'm starting to feel like my problems start appearing at a very fixed size (like you, a few hundred or so). Do you see this in other programs (bash, vim, etc)? or only psql? merlin

I've only noticed it in psql, but there are not that many other programs
that I tend to paste lots of input into.
(experiments...) Hmm, and another interesting thing is that it only
seems to happen on my HPUX system, which is (intentionally) running a
pretty ancient version of readline ... 4.2a looks like. My Fedora 10
box with readline 5.2 eats the same amount of pasted text without
indigestion. What readline version are you using?

My Fedora 10 > box with readline 5.2 eats the same amount of pasted text without > indigestion. What readline version are you using? I'm currently using 'ubuntu intrepid', which has very modern everything (readline 5.2-3 build1). I've noticed this problem since the beginning of time now. This is definitely a 'psql + something' problem...I can paste into psql query buffer editor (vim) following a /r/e with no problems, but not directly into psql itself. Another interesting point: the problem manifests with pasts over a certain size, but tends to bork at a particular point. The size of the psql window affects this...smaller windows are more tolerant of larger (but still not very large) pastes. merlin

Whenever I have a huge chunk of text to paste into psql, I'll drop to an editor with \e, then paste it, the close the editor (I have $EDITOR=vim). Just a thought.
