In gitlab issue I already mention libvirt as a packaged thus I had the impression that this one was covered: https://gitlab.com/wireshark/wireshark/-/issues/17822#note_815677078 It is factually incorrect to state that nothing depends on our libraries in Debian: root@73c5830ef791:/# apt-cache rdepends libwireshark14 libwireshark14 Reverse Depends: ... libvirt-wireshark root@73c5830ef791:/# cat /etc/issue Debian GNU/Linux 11 \n \l root@b396a73800b0:/# apt-cache rdepends libwireshark15 libwireshark15 Reverse Depends: ... libvirt-wireshark root@b396a73800b0:/# cat /etc/issue Debian GNU/Linux bookworm/sid \n \l # apt-cache show libvirt-wireshark Package: libvirt-wireshark Source: libvirt ...

Generally I'm open to learn new things, but after not being able to find reverse dependencies of libwireshark* I hope you don't mind that I take your advice on packaging with a grain of salt. From Geany's description: About ----- Geany is a small and lightweight integrated development environment. It was developed to provide a small and fast IDE, which has only a few dependencies from other packages. Another goal was to be as independent as possible from a special Desktop Environment like KDE or GNOME. So it is using only the GTK+ toolkit and therefore you need only the GTK+ runtime libraries to run Geany. As you can see Geany's goals are very different from Wireshark's and Geany not providing shared libraries aligns with having minimal dependencies. Speaking of packaging non-trivial applications I maintained systemd and glibc among other things in Ubuntu in the last few years thus I have some experience in the area. > > IMO it is easier mentally to have a single library ABI policy because > > we ship only public libraries.

The libraries were not > intended to be public until you stepped in, by the way. I'm wondering if others did understand what I tried to say here. As you pointed out in [2] there were recurring queries to make the then private libraries more widely available and I accept the credit or blame to help a lot in making the ABI stable and available for external projects. > > Also if libwsutil (with wmem_alloc) became private in 3.6.x then > > libvirt had a much harder time continuing the maintenance of their > > plugin starting with 3.6.0. > > No. Nobody said anything about 3.6.x and none of that is true. This was a hypothetical example of what would happen if we moved libwsutil to a private library location with no ABI stability promise. And wmem_alloc did move to libwsutil in [3].
