Copy and Paste does not work properly via Xpra, it just copies plain text instead of the formatted text

Describe the bug Copy and Paste does not work properly via Xpra, it just copies plain text instead of the formatted text

System Information:

Server OS: Rocky Linux release 8.8 (Green Obsidian) Client OS: Windows 10 Home 22H2 Xpra Client Version: 9.0 Xpra Server Version....

I have a Rocky 8 VM where our software is sitting and we can access it via Xpra, it works well. My problem is that it seems Xpra ruins somehow the formatted text what I would like to copy from the server (Xpra) to my notebook (windows client) to Excel.

This is the table what I would like to copy...

ScreenShot_16087

...and it looks as follows if I copy this straight from the Virtual Machine to my Excel sheet...

ScreenShot_16088

As you can see above, it kept the formatting. And this is how it looks if I copy the same info from a browser from Xpra...

ScreenShot_16089

ScreenShot_16090

As you can see it just copies the plain text, however I would need the formatted text.

Could you please let me know if there is any solution for my problem?

Many thanks in advance, Mike

Please run both client and server with -d clipboard

5.0.2 is old

v9 does not exist.

Many thanks for the quick answer! Should I add this parameter to the xpra.conf file? Or the xpra.service should contain this? Could you please send me the exact syntax?

Many thanks in advance, Mike

I believe this ticket should be moved to the https://github.com/Xpra-org/xpra-html5 project since the screenshot and the "v9" specified seem to indicate that this is the type of client used. Please try with the python client first to verify that the problem is specific to the html5 client.

Hello @totaam,

I was following the instructions in the xpra-html5 project...

ScreenShot_16096

...and start the application like that...

ScreenShot_16095

...but it still copies just plain text from the browser to my excel sheet...

ScreenShot_16094

Did I miss something? Should I add somewhere the -d clipboard parameter?

Thanks, Mike

@mykeebot as per my previous comment, try the python client so that we can figure out if the mimetype required can be handled by the server. My guess is that the html5 client does not handle it: https://github.com/Xpra-org/xpra-html5/blob/52742e3f78fee5c098778f68094f7c58e603f22a/html5/js/Client.js#L275

Thank you @totaam. Is there any detailed description about how can I use the python client? Sorry if that's too obvious, but I'm not sure if I fully understand this request.

xpra attach tcp://192.168.1.30:10000/

Thanks for the input. I can execute the command with my OS user, but I get this...

If I set the clients folder permission to 777 it does not work neither, because it's expecting 700. I have added my OS user to the root group, but still getting the issue if the clients folder permission is 700.

Thanks, Mike

You can ignore the warnings about permissions, these are not fatal.

I have added my OS user to the root group

Probably not a good idea.

Are you sure that your server is on 192.168.1.30:10000 ? Because the client says: failed to connect to tcp socket 192.168.1.30:10000

It's just a test Rocky 8 virtual machine on my notebook, so it does not hurt to add the OS user to the root group :)

Ah okay, now it's a bit better. I did not execute the xpra start command before xpra attach. It looks as follows now...

Because of some reason it's still Connection failed.

upgrading tcp socket: ... to ssl Connection failed

The cause of this failure is in your server log. My guess is that your ssl certificates probably are invalid or cannot be verified. If that's the case, run with XPRA_SSL_UPGRADE=0 xpra attach ...

Many thanks for your suggestion @totaam. In this case I get a timeout error...

No. This is not your server log. In your previous comment: https://github.com/Xpra-org/xpra-html5/issues/273#issuecomment-1855894596 The log was '/run/user/1000/xpra/0/server.log'

I meant /var/log/messages by the server log.

Under the path what you sent me I cannot find any log file unfortunately...

It's still trying to do an ssl upgrade and failing:

Permission denied: '/etc/xpra/ssl-cert.pem

Because you're not running as root this time.

You haven't specified your command line, my guess is that you're using the one for root. Don't. I also hope that this isn't a proxy command line, to keep it simple. I would just use:

xpra start --bind-tcp=0.0.0.0:10000 --no-daemon --ssl=no

I would like to keep the server's IP if that's not real problem? I think it's getting better. I did two kind of tests...

1.) With my OS user

I restarted my VM and started everything from scratch just in case. I executed the following command in a Terminal

[comsearch@iqlr8vm ~]$ xpra start --bind-tcp=192.168.1.30:10000 --no-daemon --ssl=no

...and this is the startup log...

I'm not sure why, because I did as you suggested with the --ssl-no option and XPRA_SSL_UPGRADE=0.

Since it was still a Permission issue on the cert file, I did the same tests, but with root.

2.) With root user

I restarted my VM and started everything from scratch just in case. I logged in with root and executed the following command in a Terminal...

I'm a bit loss at this point. I'm trying to follow your instructions but it does not work because of some reason. Sorry if I miss something obvious.

Thanks, Mike

Also note that 5.0.2-r0 is not the latest version, try using the current version.

Thank you totaam. I was out for the weekend, but I will give a try as soon as possible and get back to you with the result.

Hello @totaam,

Following your new instructions with the root user, I still got errors...

ScreenShot_16125

...but it started correctly our application at the end...

ScreenShot_16124

This application is configured in the xpra.conf file. I believe that's why it started with the xpra attach tcp://192.168.1.30:10000/ command. But the application does not work properly in this case.

Could you please let me know what kind of test should I do know? As you may remember, at the beginning of the ticket I described that the copy and paste function works OK if I do this straight from my virtual machine, copying the text to my excel sheet on my notebook. But if I do this from the browser with Xpra, it breaks the formatting and I just get a plain text in my Excel.

Thanks, Mike

This application is configured in the xpra.conf file.

How and why?

I believe that's why it started with the xpra attach tcp://192.168.1.30:10000/ command

And that's why you should probably not do that. Start your applications with xpra start, connect with xpra attach. Mixing is confusing.

But the application does not work properly in this case.

How so?

the copy and paste function works OK if I do this straight from my virtual machine

Does this work with the xpra client? (not the html5 client) If the xpra python client can copy the correct mime type, the html5 client can be taught to do the same. If not, then that's going to be much harder.

Hi @totaam,

So let's start with some background info. We have a Qt based software, running under linux and we use Xpra to be able to access the software via a web browser on port 14500. The /etc/xpra/xpra.conf file looks as follows...

#
# This is the default configuration file for Xpra
#
# You can provide default values for most command line
# options here.
#
# The configuration files in the conf.d directory will
# be parsed first.
#
# Each user may also define its own options in the file
# ~/.xpra/xpra.conf which will take precedence over this file.
#
# Most options can also be overriden on the xpra command line.
# See "xpra -h" or the man page for details.
#
# Syntax:
# - Options which can be turned on or off will accept
#   the following values: 1, 0, true, false, yes, no
# - Options which can accept multiple values
#   may just be specified multiple times.
# - You may break a long line into multiple lines
#   by ending each line with a backslash '\'.
# Starting iQ.link automatically after logging into Xpra
start-on-connect=/opt/iqlink/current_version/start_link

# Terminate all the child commands on server stop. Default: no

# Exits the server when idle (0 to disable). Default: 0 seconds

# 393216 = 384 kbps
# bandwidth-limit=393216
bandwidth-limit=384k

# Which image compression algorithm to use. Default: auto.
# auto - default mode: the built-in heuristics will choose the most appropriate encoding
# png - compressed and lossless, can be quite slow.
# png/P - compressed and lossy: it uses a colour palette, which means better compression but still slow.
# png/L - compressed and lossy: grayscale only using a palette.
# rgb - a raw pixel format (lossless) compressed with lz4, lzo or zlib (see compressors) the compression ratio is lower, but it is by far the fastest encoding available.
# webp - can be used in lossy or lossless mode, useful for graphical applications, it compresses better than jpeg and is reasonably fast except at high resolutions.
# jpeg - can be useful for graphical applications, it is lossy and usually very fast.
# vp8 - lossy video encoding which always uses colour subsampling. Fast at encoding and decoding.
# vp9 - Video encoding which supports both lossy and lossless modes, available if your ffmpeg library version is recent enough.
# h264 - One of the best encoding available: it is fast, efficient and tunable via the quality and speed options.
# h265 - Far too slow at encoding, avoid.
# encoding=h264
encoding=auto

# This option sets a fixed image compression quality for lossy encodings (jpeg, webp, h264/h265 and vp8/vp9). First, one of those
# lossy encodings must be enabled with --encoding or when using the default auto mode. Values range from 1 (lowest quality, high
# compression - generally unusable) to 100 (highest quality, low compression). Specify a value of zero to let the system tune the
# quality dynamically to achieve the best bandwidth usage possible. It is usually best not to use this option and use min-quality instead.
# quality=0

# This option sets the minimum encoding quality allowed when the quality option is set to automatic mode. See quality above.
min-quality=5

# This option sets the encoding speed, from 1 (slowest) to 100 (fastest). Slower compresses better and will use less bandwidth,
# faster will give better latency as long as there is sufficient bandwidth. The system normally uses a variable speed, this option
# forces a fixed speed setting to be used instead. It is usually best not to use this option and use min-speed instead.
# speed=50

# This option sets the minimum encoding speed allowed when the speed option is set to automatic mode. See speed above.

Everything is smooth with these options. Our software mainly works as expected in a browser via Xpra. I have also sent you the content of the xpra.service in one of my previous comment.

Our problem is that if I copy a text from our software via Xpra, it only copies a plain text into Excel on our notebook. If I do exactly the same, but not from the browser but straight from the linux virtual machine, it works OK. It keeps all the HTML formatting. That's why I reported this ticket.

Since I'm not an expert, I just tried to follow your instructions, using the linux virtual machine where our software and Xpra is sitting. It's a LAB (test) environment actually. So I was following the instructions and at the end I could use the commands suggested by you (with root), but that's just started the software which is configured in our xpra.conf file. On this way it does not work properly, I cannot open the menus, the buttons are blinking, etc...

I just really would like to find the way to be able to copy and keep the formatted text from a browser via Xpra.

Thanks, Mike

You are still not testing with the current version. And also not answering the key question: do you get the correct clipboard data type using the python client, yes or no?

Hi @totaam,

Finally I managed to work this... The problem was that when I executed the XPRA_SSL_UPGRADE=0 command in the terminal, I did not use the export XPRA_SSL_UPGRADE command right after that. So, I executed the following as the root user...

[root@iqlr8vm ~]# XPRA_SSL_UPGRADE=0
[root@iqlr8vm ~]# export XPRA_SSL_UPGRADE
[root@iqlr8vm ~]# env | grep XPRA
XPRA_SSL_UPGRADE=0
[root@iqlr8vm ~]# xpra start --bind-tcp=192.168.1.30:10000 --no-daemon

...and below is the output...

This started our software and I could do the requested test. I copied the text...

ScreenShot_16130

...and pasted into Excel...

ScreenShot_16131

All looked OK.

After that I connected from browser to the session which attached to the previously started session on the server...

ScreenShot_16132

I also copied the same text, but this time via browser and it just copied the plain text...

ScreenShot_16133

So it seems the problem is with the html5 client. I know that v5.0.2 is not the latest one. If you want, I will update Xpra later and I will re-do these tests.

Thanks, Mike

Ok, so I guessed correctly when i moved this ticket to the html5 client.

Please run your server with -d clipboard and post the log. With the bare minimum actions needed as the log grows quickly.

Hello @totaam,

Yes, you were right.

Do you mean...

xpra start --bind-tcp=192.168.1.30:10000 --no-daemon -d clipboard

...or?

Hello @totaam,

That was in the terminal after I hit Ctrl+C...

Thanks, Mike

I assume that this a log for a failing copy? Because it's sending the data as text/plain:

2023-12-19 10:05:52,739 _do_munge_raw_selection_to_wire(text/plain, text/plain, 8, <class 'bytes'>:4093)

Do you have the same log but for a successful copy?

It will choose one of the other targets:

2023-12-19 10:05:52,710 got_targets: ('text/plain', 'UTF8_STRING', 'STRING', 'TEXT', 'text/html', 'application/vnd.oasis.opendocument.text', 'TARGETS', 'MULTIPLE', 'TIMESTAMP', 'SAVE_TARGETS')

Perhaps application/vnd.oasis.opendocument.text According to Mime Content Types used in OpenOffice.org, that's OpenDocument Text. Odd when they have other datatypes for structured data, but who knows, maybe that's enough for the spreadsheet.

Assuming that this is the case, we may be able to use ClipboardItems. I'm not sure that evt.clipboardData.setDatacan be used here.

Hi @totaam,

Yes, below you may find the output of the successful copy...

Please do let me know if you need any other info from my side.

I hope it helps, Mike

Oh, it's using text/html for the structured data, we should be able to handle that easily enough.

Sounds great! :) Please do let me know if you have any update on this!

Hello @totaam!

Happy New Year! I hope you are doing great!

I'm just wondering if you have any update on this ticket since then? Do you need any other tests from my side?

Thanks in advance, Mike

@mykeebot there are 37 issues open at time of writing with the xpra-html5 project, and another 270+ with xpra. So no, no progress likely anytime soon.

Hi @totaam,

Thanks a lot for your feedback, understood. Do you have any gut feeling about when can you implement this fix? In 1, 3 or 6 months? I just would like to manage my resources.

Kind regards, Mike

Testing with a nested firefox browser for convenience, connecting with chrome.

Selecting text triggers:

got_targets: ('TIMESTAMP', 'TARGETS', 'MULTIPLE', 'SAVE_TARGETS', 'text/html', 'text/_moz_htmlcontext', 'text/_moz_htmlinfo', 'UTF8_STRING', 'COMPOUND_TEXT', 'TEXT', 'STRING', 'text/plain;charset=utf-8', 'text/plain', 'text/x-moz-url-priv')

So the browser running in the xpra session does offer text/html5, and the commit above makes the html5 client prefer this format over text/plain. Hopefully this won't cause us too many problems. The browser's clipboard interface is very limited (and convoluted, and not supported with the same features on all browsers...), so we can't easily choose which format to use, or even supply multiple formats it seems.

That's only half the solution unfortunately, on the server side we also need to:

honour what the client requests: https://github.com/Xpra-org/xpra/commit/1058078f1016d72bb5a41a630d7775d92e87a60f
add text/html to the text targets : https://github.com/Xpra-org/xpra/commit/2d586b41cd3d1d7503d48b66b15b397d8ff4dc58

This does not solve the issue of copying in the other direction: text/html5 from the browser to the server. I found some bugs there too...

How can we choose the format to use with DataTransfer.getData? Surely we aren't meant to try mime-types at random?

So now for copying to the server:

I seem to need 922c36723daea1476a1ec289312773bb24404017 to unescape() the URI encoded data - is this new? Why wasn't this needed before?
75652df303c3f3ebd3b10b3deb3f0972391a6be7 tries to use getData("text/html") and falls back to the previous read_clipboard_text if that fails - it should be fine

Unlike the commit in the comment above, which will be included in the next 10.x release, these two are in git master only, at least for now.

@mykeebot does that work for you? I have pushed some updated builds for rocklylinux 8.8 in the beta repository.

What browsers do you have for testing? What client OS and browsers are you targetting?

Hello @totaam,

Many thanks for your input! I need some time to review the details and make the necessary changes, then test it. I will get back to you as soon as possible.

Talk to you later, Mike

Hi @totaam,

Hello @totaam,

I had some time so I went through on your comments. Based on my best understanding, I had to modify the clipboard.py and core.py files. I could find these on my virtual server (where Xpra is sitting)...

/usr/lib64/python3.6/site-packages/xpra/x11/gtk_x11/clipboard.py /usr/lib64/python3.6/site-packages/xpra/clipboard/clipboard_core.py

I made the changes what you have suggested in your first comment five days ago, then I restarted the server. Now, when I execute the following commands...

[root@iqlr8vm comsearch]# XPRA_SSL_UPGRADE=0

I have already double-checked the code changes what I have made and I think it's OK. I used spaces and not tabulators in the code of course.

Do you have any idea about what could be the problem?

Thanks in advance, Mike

Based on my best understanding, I had to modify the clipboard.py and core.py files

No. I specifically said: I have pushed some updated builds for rocklylinux 8.8 in the beta repository.

TypeError: 'type' object is not subscriptable

My guess is that you applied the commits from git master to your v5.x installation. That's not going to work as RHEL 8 uses python3.6 and xpra v6 requires python3.10 or later. Either use the commits for the v5.x branch: https://github.com/Xpra-org/xpra/commit/eaf2e5472b7a3f775d2fd3a6944804eaa833f268 + https://github.com/Xpra-org/xpra/commit/0da4d81741fed523e1d356f8ab3fce209cdbd221 or use the beta builds provided.

And if you want to test with v5 rather than v6, this is also available from the beta repository:

dnf list xpra --showduplicates

Then choose your version from there, ie:

dnf install xpra-5.0.5-10.r36.el8

Hi @totaam,

Sorry, I thought I still have something to do before I go with the beta binaries. So what I did...

1.) I configured the Xpra Rocky Linux 8 beta repository on my VM....

How did you copy to the clipboard? Have you tried using control-c? Xpra may not be able to access the clipboard from pointer events.

Also, it doesn't look like you have an updated xpra-html5 package installed, I may have forgotten to push new beta builds of this component.

If that's not the cause then it is possible that Excel needs a different mimetype.

I will look into why xpra-x11 required an extra step to upgrade, it should not be needed.

How did you copy to the clipboard?

Ctrl + A, then Ctrl + V, then trying to pate with Ctrl + V.

Have you tried using control-c?

Yes.

Xpra may not be able to access the clipboard from pointer events.

I'm not sure what does pointer events mean.

Do you need any further tests from me now?

I'm not sure what does pointer events mean.

The pointer is usually driven by the mouse device. Click, move, scroll, etc..

Do you need any further tests from me now?

Yes, please try with the updated xpra-html5 package. It was missing because of this issue which caused the RHEL 8 builds to fail: e384d3ff64c3362a1ae11c79e90ce0a29c8b157f

Thanks, Mike

Yes, make sure that xpra-html5 is updated when you do. dnf clean metadata if needed.

Hi @totaam,

I'm happy to confirm that with the latest xpra-html5 upgrade the Copy & Paste function works OK and keeps the formatting as expected....

Will you keep these binaries in the beta repository? I would like to do the same upgrade in the production environment soon.

Many thanks in advance, Mike

Xpra-org / xpra-html5

Copy and Paste does not work properly via Xpra, it just copies plain text instead of the formatted text #273
