Description Marc Schipperheyn 2012-01-27 06:12:32 UTC
If we take this page 

And copy the table of cities and try to copy it into Calc or Write, you get a hang on all open LibreOffice windows. 

AFAIC there are three major problems here:
1. a hang in one window can hang all windows
2. a paste of something that LibreOffice can't process properly, leads to an unrecoverable hang in stead of an error message
3. a paste of a pretty standard HTML table copy is not processed properly

I'm on Windows 7 64bit
Comment 2 mgs 2012-03-07 06:59:20 UTC
I have had this problem for a long time with OpenOffice (as far as I remember) and LibreOffice, various versions up to and including 3.5.0, under Microsoft Windows 7/32 (possibly XP too). Basically, I can either copy almost any web page into LibreOffice, or enter the URL of one as the filename in LibreOffice Writer. The web page will appear, and some editing can be started, but soon LibreOffice abends. Probably the same as
During the time I have been having this problem I have uninstalled and reinstalled Open/LibreOffice to no avail.

After the abend LibreOffice Writer will sometimes not run again; Windows task Manager shows it as running (though with no display). Killing all running instances of Writer allows normal operation again.

I report what I find; it may affect other components than Writer and for other operating systems.

Sir Hangs-A-lot is still present on LibreOffice and in x86_64 as well, as my OS is 64 bit, Linux based OS.  

HANGS when copying, pasting, manipulating tables that I copied from HTML. 

And when saving documents with that tables. 


I have the portable version of LO 4.0.3 32 bit for Windows, and hangs as well.
Comment 6 Matthew Francis 2015-01-21 07:55:34 UTC
This seems to be a result of loading - slowly - the large number of small images in the copied HTML. Pasting a smaller subset of the table finishes after a few seconds

I cannot reproduce it on a computer with Core-7 processor and 8 GB of RAM with neither LO version. 
Can you please retest with current LO and write LO version and hardware specs (processor, RAM)?

I agree with this analysis. This backtrace shows the code waiting for image data from the remote server.

The backtrace is from a build of current git master, ie future version 5.1.

If I paste the text from the wikipedia article as unformatted text (Ctrl+Shift+Alt+V), the paste operation happens very quickly.

I think that the problem from a users' point of view, is that during this long loading process, there is absolutely no feedback to the user, and the UI is unresponsive.

I wonder if there is any way that the loading of such images can be postponed as a background job?

I'm setting to NEW as I think there is enough information here to work with.
Comment 11 kie000 2015-09-08 16:49:06 UTC
An office application shouldn't be loading anything from the web during a copy. 

When I copy something I expect data -> clipboard -> Libreoffice, not for Libreoffice to start acting like a web browser and fetching stuff from the internet. And no option is offered - typically I don't want the objects, just the textual data.

Separately, when I paste the example data from wikipedia, Calc does paste the data but the formatting goes so bad that it's for all intents useless.
Comment 12 Timur 2017-05-24 16:21:02 UTC
As I wrote in Comment 8, I was never able to repro this (but I did with Bug 91237). So please retest this one with current LO.

Comment 14 Telesto 2017-05-24 18:04:03 UTC
LibO is fully unresponsive when copy/ pasting the table from Firefox to Writer. It takes up to a minute or so (no crash):

It seems to me (but I'm no Dev) that LibO is trying to download every image at once, creating a flood of TCP connections (I used TCPview). This is the normal behavior since LibreOffice 3.3.0 OOO330m19 (Build:6) tag libreoffice-

OpenOffice AOO413m1(Build:9783) at the other hand uses only 2 endpoints (and the pasting does go a lot faster)
Comment 15 Michelle 2017-06-13 19:51:00 UTC
I just tried to copy some text including tables from https://www.humanservices.gov.au/customer/enablers/working-out-child-support-payments-using-basic-formula and it crashed LibreOffice completely.  I had several Calc files open as well, and on trying to restart LibreOffice, it tried to recover those files I had open, but all had "disappeared" & could not be recovered.  The other Writer file I had open also reverted to unnamed document.  The information provided to me on first crash follows:
This bug was filed from the crash reporting server and is br-a3368511-e014-4417-8341-e75fe41a7b53.
Comment 16 kie000 2017-06-13 20:31:24 UTC
I just want to say me too, crash recovery is very hit and miss, it gets confused and does weird things.
Comment 17 Telesto 2017-06-13 20:54:53 UTC
@Michelle from comment #15)
Looks like bug 105769. This only affects the 64-bit version. Please try with the 32-bit build or use the x64 5.4 beta version
Comment 18 Kruno 2018-05-12 08:56:32 UTC
I don't think it only affects 64-bit systems as I got hang on 32-bit, but now in seams it does not hang anymore.

Comment 20 francois@synways.com 2018-08-17 10:24:07 UTC
I have also the issue copying html table.

Version: libreoffice 1:5.2.7-1+deb9u4 amd64 on debian stretch

I have the bug when my vpn is connected.

When using vpn, I also use a remote proxy with a ssh tunnel: ssh $myproxy-hsot -L 3128:
Then I can either setup the proxy settings (http(s): 3128) in the gnome system settings or in the libreoffice options (manual proxy settings)
In both cases  the pasting works without bugs. (it is just a bit slow)

If i do not set the proxy in system nor in libreoffice and set it only in firefox manually, then obviously firefox can reach internet and libreoffice cannot.
In this case copy pasting an html table with pictures elements will hangs libreoffice forever and I need to force close it.

=> libreoffice should not need internet for pasting clipboard.
=> if internet cannot be avoided, at least libreoffice should give up after some timeout and/or offer a cancel button, instead of freezing a loosing changes on all opened documents.
Comment 21 kie000 2018-08-19 09:15:19 UTC
Just another me too - I always use VPN. (because snoopers charter makes 1984 look good).

Comment 23 Timur 2018-11-29 10:05:17 UTC
I guess all those Bug 45307, Bug 43338, Bug 91237 have the same root, management of remote images fetch. 
If reproducible or not depends probably more on internet link and load than on computer type. 
Maybe we can close all those and open a new enhancement for TCP session management.
Comment 24 kie000 2018-11-29 11:00:31 UTC
It took an hour to copy the example table. Firefox hung for about 20 minutes and then LibreOffice took about 40 minutes of doing pretty much nothing. What's with all the waiting?

Is windows clipboard trying to use the internet? Is LibreOffice trying to use the internet? That's not how clipboard or copying should work.

During that hour+ of waiting LibreOffice was unresponsive. 

Windows clipboard was out of action for the initial 20 minutes when the Firefox tab was doing it's thing. During this 20 minutes the only thing that could be pasted anywhere was the text only part of the copy, other copy (not paste) actions failed.

Win7 64bit 16GB Ram, Fast SSD

LibreOffice (x64) Calc

Calc might have crashed on lesser hardware.

I don't care if LO crashed or not, LO should not be trying to use the internet when I'm doing a simple copy-paste, that's bad programming, just paste the contents of the clipboard already, it should not take an hour on a fast machine with fibre internet.
