Fulltextsearch hangs with complex PDF due to Ghostscript bug in version 10.0.0

I know this is not related to Fulltextsearch but I thought to put the information in here to let people find a simple solution a little quicker:
Ubuntu 23.04 serves with Ghostscript version 10.0.0. Also the Nextcloud docker image serves with GS 10.0.0.

During an indexing process, I noticed that it got stuck on a particular PDF file, and I found out that a simple text extraction via Ghostscript was hanging.

I went to the official GS site and downloaded Ghostscript 10.02.0 Source:
https://ghostscript.com/releases/gsdnld.html

• uncompress it: (f.e. tar -xvf ghostscript-10.02.0.tar.gz)
• go into this folder
• sudo ./configure
• sudo make install
• restart Terminal
• Test with gs -v

If you get "cannot find -lXext" during the linker stage simply install

Under Ubuntu:
sudo apt-get install libxext-dev
Under Fedora
sudo dnf install libXext-devel
Arch Linux
sudo pacman -S libxext

And do the build again.

Find out where your gs is located with which gs and replace the binary.
I have built it on an Ubuntu 23.04 and copied the binary into the official Nextcloud docker image.

gs -version
GPL Ghostscript 10.02.0 (2023-09-13)

That solved my issue with a hanging index run.

May it help!

The report concerns indexing a complex PDF with Ghostscript 10.0.0 in Ubuntu 23.04 and the Nextcloud Docker image; no project files or tests are named. Start by checking the full-text indexing path and reproducing the hang with the affected PDF and Ghostscript versions. Done would require a confirmed project-level fix or documented handling of the dependency issue.
