[SOLVED] Due to the disk space requirements of mongodb (needs nearly 200G in default configuration), the ~/.cache/pikaur directory was a symlink to an NFS share with more capacity. The interaction of that absolute path was causing the permissions to be 750. I'm not 100 percent clear on why that was the case, but now that I'm using mongodb-bin, I don't need the symlink any longer. Removing that symlink caused pikaur to create a new directory in its place, and the `stat` commands I placed into the plex-media-server PKGBUILD indicate 755 permissions now.
Original post:
I've noticed that, at least with plex-media-server and unifi, the permissions stored in the pkg tarball generated by pikaur (my chosen AUR helper) have 750 permissions (instead of the expected 755). I can't figure out why this is happening. Here's the output of the command:
tar -tvf ~/.cache/pikaur/pkg/plex-media-server-1.18.0.1944-1-x86_64.pkg.tar.xzhttps://git.eldon.me/trey/pastes/src/br … 4-1.output
Most of the executable files to be placed in /usr/lib/plexmediaserver have -rwxr-x--- (750) permissions, instead of the expected -rwxr-xr-x (755) permissions. I can fix this by issuing the command
sudo chmod o=rx -R /usr/lib/plexmediaserveror even
sudo chown plex:plex -R /usr/lib/plexmediaserver...but I'd rather fix it at the source (because the first command will make some files executable when they don't need to be).
Here are my relevant pikaur.conf, /etc/makepkg.conf, and ~/.makepkg.conf:
https://git.eldon.me/trey/pastes/src/br … ikaur.conf
https://git.eldon.me/trey/pastes/src/br … kepkg.conf
https://git.eldon.me/trey/pastes/src/br … kepkg.conf
I don't see where the 750 permissions are coming from, but maybe I'm missing something. This is only happening on one of my Arch hosts, and I use pikaur everywhere I can. I know it's a configuration setting on the affected host, but I can't seem to find out where.
EDIT: I just upgraded plex-media-server, and there are a lot of messages like this in the output:
warning: directory permissions differ on /usr/lib/plexmediaserver/Resources/Tuner/Shared/scanners/clearqam/transponders/
filesystem: 755 package: 750
warning: directory permissions differ on /usr/lib/plexmediaserver/Resources/Tuner/Shared/scanners/dvbc/

filesystem: 755 package: 750
warning: directory permissions differ on /usr/lib/plexmediaserver/Resources/Tuner/Shared/scanners/dvbt/transponders/
filesystem: 755 package: 750So pikaur recognizes the difference between the filesystem and the permissions within the pkg tarball.
EDIT2: I forgot to mention, my umask is 022, for my regular user and root. Also, in the PKGBUILD there is the command
install -d -m 755 "${pkgdir}/usr/lib/plexmediaserver"...so I'd expect the permissions to be 755, based on my umask and this install command.
I've already escalated to the maintainers of both `plex-media-server` and `unifi` (which has a similar problem). Because both packages are exhibiting the same behavior, I thought it was the pikaur and/or makepkg configuration, rather than something within the PKGBUILD files themselves.

If you install devtools then build the package with extra-x86_64-build is the issue still present?

I get some warnings with extra-x86_64-build while PWD=~/.local/share/pikaur/aur_repos/plex-media-server. It does appear to finish, however. The resulting pkg tarball has the following output:

...So that looks correct. I'm not all that familiar with devtools/extra-x86_64-build, it looked like it tried to install the package (but failed because plex-media-server includes a lot of its own versions of a bunch of libraries).

As the permissions generated by extra-x86_64-build are correct it suggests to me the issue is the build environment on your system.
What is the result if you use makepkg directly instead of pikaur?
Edit:
Also is cp an alias on that system?

type -a cp
cp is /usr/bin/cp
cp is /bin/cp
cp is /sbin/cp
cp is /usr/sbin/cpSo no aliases, and the first cp found in my PATH (`which cp`) is /usr/bin/cp. I haven't posted an issue upstream (GitHub). I suppose that's my next step.

I'll see what upstream has to say.

Agreed looks as though the issue is in the source extraction or setup of the $src directory.
install -d -m 755 "${pkgdir}/usr/lib/plexmediaserver"Creates the plexmediaserver directory
cp -dr --no-preserve='ownership' "${srcdir}/usr/lib/plexmediaserver" "${pkgdir}/usr/lib/"The directories contents and attributes (ownership and permissions) come from the cp command.
If mode was added to the --no-preserve option as in
cp -dr --no-preserve='ownership,mode' "${srcdir}/usr/lib/plexmediaserver" "${pkgdir}/usr/lib/"then the mode would be set by umask but as you mentioned in your original post that has the same issue as recursive chmod.
