PDF export with space in name fails on collabora online
Describe the bug Trying to export PDF or Print just fails. Otherwise everything works fine. Seems the PDF export from CODE is still buggy.
To Reproduce Steps to reproduce the behavior:
- Try downloading file as PDF or printing.
Expected behavior File downloaded as PDF
Actual behavior Error stating "Document cannot be exported. Please contact the storage server administrator."
Additional context I run self hosted CODE, installed from deb/ubuntu packages (22.05.4-1) on VM (no docker involved, so I believe it's different from #2041), and I haven't tampered with links, so I believe #5039 is also not a case, even though all of these are very similar.
Checking logs, looks like the same function is being called for both doc and pdf export, but pdf fails, but doc succeedes:

I've tried running collabora with debug and trace logs, but nothing helpful is found in them except the above mentioned line.
All the times same getLOKitDocument->saveAs is being called https://github.com/CollaboraOnline/online/blob/a149398e971e094960b1355fe203b2ba181fa71b/kit/ChildSession.cpp#L1078 but as I don't know the code much I wasn't able to track it down to some reasonable point.
I've checked if there might be some problem with the jail of the collabora for the /dev/random issue. Symlinks are fine even though I am not sure if they are needed any more as they point to ../tmp/dev/random, which is empty and as the cool have the cap_mknod+ep it's able to create the devices directly in /dev/ jail, and in my case there are real dev created in /opt/cool/child-roots/tmp/somestring/dev ). Also, I've noticed the coolwsd-systemplate-setup https://github.com/CollaboraOnline/online/blob/a149398e971e094960b1355fe203b2ba181fa71b/coolwsd-systemplate-setup#L75 searches for the xpdfimport, but neither in my installation or in docker image this file exists, so no extra libraries are being pulled into jail, but I assume this is fine.
I've tried attaching gdb to running processes, but I am not sure which is actually doing the export as none brought any results.
I can confirm that. Im running CODE on Debian 11 VM, no docker and no LXC. PDF export is not working.
coolwsd: 22.05.5.3 Collabora OfficeDev 22.05.5.3
Maybe this xpdfimport is meant (https://sources.debian.org/src/libreoffice/1%3A7.4.0~beta1-3/sysui/desktop/apparmor/program.xpdfimport/)?
I assume this report is for Export to PDF of any file in native CODE. durdin85 said: CODE 22.05.4-1 on which-OS? VM Alternativend said: CODE 22.05.5.3 on Debian 11.
Not clear why would this be different from https://github.com/CollaboraOnline/online/issues/5039? There is explanation which is not related only to links. Please test convert-to from https://www.collaboraoffice.com/document-conversion/ to see if Export to PDF works that way? In my case it works. Also please test if Export to PDF works for filename with no spaces? Needinfo on that.

No it´s not working without spaces. At the moment we are on COOLWSD Version: 22.05.10.1 git hash: [719ae9bf] and Collabora OfficeDev 22.05.10.5 on Debian 11 VM, Proxmox host.
22.05.12.3 when exporting, I get "The server encountered a failure error when parsing the exportas command". "download as" I get the same error.
syslog:

it doesn't work without spaces either. tried it "https://www.collaboraoffice.com/document-conversion " - it works.
if set "mount_jail_tree" to false, then the export works like this:
but the pdf appears in the file list only after the page is refreshed.
"download as" does not work. after clicking "export" nothing happens.

There were some fixes for export to PDF which should be in 23.05.1 to be released today so it would be good if you can test later.
It is still not working, I've tried 23.05.1-2 and 23.05.2-2 built locally.

If I turn off the capabilities security feature in coolwsd.xml, then both work.
I've finished setting up another local build of 23.05.1-2 on a different machine and it works on it. I'm not sure how to investigate the effective difference. I'm pretty sure the build options and configuration are exactly the same.

I'd be glad to provide more information if someone points me where to look.
Also please test if Export to PDF works for filename with no spaces?
Am running v23.05.2.1 with udocker and Export to PDF fails with:

As you can see, this is filename with spaces! Welcome to Nextcloud Hub test.docx
When renaming the file to test.docx the export works nicely!

I still get the same error.

Im on 23.05.5.3 and the export still fails.
Edit: If i turn off the capabilities in coolwsd.xml exporting documents in pdf or epub mostly works. Sometimes it crashes my Firefox but most documents are working.
Im now on:
COOLWSD version: 23.05.5.3 (git hash: 5093121f) LOKit version: Collabora Office 23.05.6.1 (git hash: 67cdcf1) Served by: Debian GNU/Linux 12 (bookworm)
but still the export only works if i disable the capabilities.
This is a problem that has plagued me for months, and I finally found a solution that hopefully others find useful. I'm running "linuxserver/nextcloud" and "collabora/code" in docker on a Synology NAS. Whenever I was trying to export/save a document as a pdf, I was getting this error in the log:
kit-3867488-3867394 2023-07-25 16:50:25.458213 +0200 [ kitbroker_002 ] ERR ToMaster-002: error: cmd=exportas kind=failure| common/Session.hpp:165
wsd-3867380-3867551 2023-07-25 16:50:25.458249 +0200 [ docbroker_002 ] ERR ToClient-002: exportas error failure: failure| wsd/ClientSession.cpp:1623
What FINALLY fixed the error for me was adding --o:security.capabilities=false to my extra_params. Now, I don't think that ALONE is all it takes to fix the issue, it was just the last missing ingredient for me. Here's what my collabora docker-compose looks like
collabora:
image: collabora/code
environment:
- aliasgroup1=https://mynextclouddomain.com
- extra_params=--o:security.capabilities=false --o:security.seccomp=false
- dictionaries=en_US
- server_name=mycollaboradomain.com
security_opt:
- seccomp:unconfined
privileged: true
cap_add:
- MKNOD
There was a lot of other tweaking I had to do originally to get things working with collabora, nextcloud, and my reverse proxy that I've long since forgotten, but I don't think they were relevant to this issue.
