And when upgrading to a new stable there are several cycles where triggers run at the end (you might not notice since the package manager takes care of it). On a bookworm -> trixie upgrade the man-db trigger might run 5 or 10 times instead of 1000 packages each executing the command, but it will definitely run more than once. If one of the dependencies of texlive-binaries Pre-Depends on zlib1g, this might be sufficient to ensure that all pending triggers are running after the upgrade of zlib1g and before the upgrade ot texlive-binaries. > Hilmar cu Adrian

[2] And from then zlib1g still has the Breaks: texlive-binaries (<< 2009-12) that will also require updating again. Is there any reason why the check exists at all? If the only effect is breakage every 10-20 years, then it's wrong to keep it. This check would make sense if zlib would make buggy changes where the ABI changes without chaning the library soname, but that is not supposed to happen and if it would happen with a library as widely used as zlib then so much would break in unstable that the revert would be instant. > Hilmar >... cu Adrian

It is. https://www.lua.org/manual/5.3/manual.html#lua_error int lua_error (lua_State *L); Generates a Lua error, using the value at the top of the stack as the error object. This function does a long jump, and therefore never returns (see luaL_error). The SIGABRT is generated by calling abort(): https://sources.debian.org/src/lua5.3/5.3.6-2/src/lapi.c/#L1117 https://sources.debian.org/src/lua5.3/5.3.6-2/src/ldebug.c/#L649 https://sources.debian.org/src/lua5.3/5.3.6-2/src/ldo.c/#L130 > Hilmar cu Adrian

That crash is the fault of lua_error(L). Removing the version check including the call to lua_error is the proper fix for this. If any of the binaries of texlive-bin require a minimum version of the zlib, this needs to be reflected in Depends and not with a deliberate crash. > > 2. ensure texlive-bin has package dependencies that match this runtime > > check > > The zlib people, did not change the API version or created a version > statement in the depends line like "Depends: ... zlib1g (>= 1:1.3)", hence > I'd add an artificial "Breaks: ... zlib1g (<= 1:1.2.3)" to my > texlive-binaries package to make sure 1.3 is in place, when the new > texlive-binaries comes in. Correct? No, that's certainly the incorrect fix. Especially if that is hard-coded. Cheers -- Sebastian Ramacher

I hope lua_error(L) is not the equivalent of "exit with SIGABRT". ;-) I still suspect that something broke in the API of zlib, the zlib people are not aware of. 2. ensure texlive-bin has package dependencies that match this runtime check The zlib people, did not change the API version or created a version statement in the depends line like "Depends: ... zlib1g (>= 1:1.3)", hence I'd add an artificial "Breaks: ... zlib1g (<= 1:1.2.3)" to my texlive-binaries package to make sure 1.3 is in place, when the new texlive-binaries comes in. Correct? And it also might affects users directly, without proper dependencies e.g. a bookworm -> trixie upgrade might end up with the following order (among many other things happening during the upgrade): 1. zlib gets upgraded 2. the tex-common trigger runs 3. texlive-bin gets upgraded If this is permitted by the dependencies, then step 2 must not fail. I'd rather expect that the triggers run at the end of the setup process, i.e. after all packages replaced their files. At least this was the original ideal behind them IIRC.

A proper fix would be either to: 1. patch the version check out of texlive-bin (preferred), or 2. ensure texlive-bin has package dependencies that match this runtime check After a binNMU the migration of zlib to testing would still be blocked forever by the autopkgtest of packages like asymptote that will continue to test with zlib/unstable and texlive-bin/testing. And it also might affects users directly, without proper dependencies e.g. a bookworm -> trixie upgrade might end up with the following order (among many other things happening during the upgrade): 1. zlib gets upgraded 2. the tex-common trigger runs 3. texlive-bin gets upgraded If this is permitted by the dependencies, then step 2 must not fail. > Hilmar cu Adrian
