Re: %lua_requires behaves differently in F33+

Aug 30, 2020 02:04:36 Miro Hrončok :

Establish a FAS group for "Lua provenpackagers". Make sure the name it 
not to be confused with the Lua SIG, but note that the FAS group usually 
needs to be called ...-sig. I'd go with lua-packagres-sig or 
lua-maintainers-sig. Get it a mailing list needed for Bugzilla, e.g. 
lua-packagres-sig@lists. Don't mention it anywhere :)




Well, it is mentioned here :)

I'll go with packagers. lua-maintainers-sig is too close to the 
lua-maintainers@ email alias for those with commit access to the lia RPM.


Thanks!

You can look at the ticket I opened for creating the @java-maint-sig
group and mailing list for inspiration :)
https://pagure.io/fedora-infrastructure/issue/8902

We also have two mailing lists like python - java-devel@lists is the
old list,  for general and public discussion, and java-maint-sig@lists
is the new private list for the group's bugzilla account.

Not only it is overkill, but it brings problems.
For the story, see this ticket:

https://pagure.io/fedora-infrastructure/issue/5478

tl;dr the python-devel list is open to anybody
  the python-sig is a private (bugzilla mostly) list for the packaging group
  people are confused why cannot they see the python-sig list
  even when they are members of the Python SIG

For a new SIG I'd do the following:

Establish a FAS group for "Lua provenpackagers". Make sure the name it not to be 
confused with the Lua SIG, but note that the FAS group usually needs to be 
called ...-sig. I'd go with lua-packagres-sig or lua-maintainers-sig. Get it a

Establish a general mailing list about Lua. Most likely lua@lists. Mention it 
everywhere.

Presumably an Infra pagure ticket?)


Yes.

Definitely. Right now anyone pulling in lua-devel gets the macros which
is not ideal.

Yup, I've been borrowing liberally from the Python rpm-macros package
(and the updated packaging guideline I'm working on is also liberally
borrowing from the Python guidelines. Thanks for this pointer though,
I've not started looking at python-devel yet!

Will do, thanks for the interest! I figured some core developers will
be interested given how critical some Lua scripts are for packaging.

Quick question: for Python there's both python-devel and python-sig --
this seems overkill for Lua, right? Would starting lua@lists be enough?

(Also, I couldn't find documentation on starting a new mailing list.
Presumably an Infra pagure ticket?)

Please make it conditional on rpm-build. That way, Lua developers not interested 
in RPM packaging won't get unneeded packages.


See python3-devel:

Yes, this is done by the automatic dependency generator in Fedora 33+:

https://src.fedoraproject.org/rpms/lua/pull-request/3

It is written in Lua (ha!), so it requires RPM 4.16+ (for parametric dependency 
generators). It could be backported to Fedora 31/32 if rewritten as a Shell script.

I've created a review request for the proposed new macro package here:
https://bugzilla.redhat.com/show_bug.cgi?id=1873676

If this is accepted:
- we can immediately branch and ship this for EL6 and EL7 so Lua
packages for those releases can use macros
- I'll get redhat-rpm-config to pull in lua-srpm-macros, the same way
it pulls in other *-srpm-macros packages
- I'll refactor lua in Fedora so lua-devel pulls in lua-rpm-macros
rather than shipping macros.lua, then enable shipping macros.lua in
lua-rpm-macros (right now it's excluded on Fedora to avoid file
conflicts)

I'll also look at creating an official SIG including having a mailing
list.

Thanks,

Partially answering this point: this is because %lua_requires is not
available on the system where rpmbuild -bs was invoked to create the
SRPM.

Some languages (e.g. Python) ship $LANG-srpm-macros packages that are
pulled in by redhat-rpm-config to address this.

So having lua-rpm-macros with potentially a lua-srpm-macros would help
here.

But this won't even be needed if we can figure out how %lua_requires
get triggered on Fedora 33+ and have it work that way on older releases
too.

%lua_requires behaves differently in F33+

2020-08-28 Thread Michel Alexandre Salim
Hi,

Björn added some useful Lua packaging macros in 
https://bugzilla.redhat.com/show_bug.cgi?id=1447324

One of them, %lua_requires, adds a dependency on either `lua(abi) =
%{lua_version}` or, on EL6 and below, on lua >= current version and lua
< next version.

Somehow this seems to be automatically applied on Fedora 33 and above
-- without adding any manual require on lua(abi)

e.g. lua-lunitx on Fedora 33
https://bodhi.fedoraproject.org/updates/FEDORA-2020-7c23dc64c0

on Fedora 32, though, the macro is not automatically invoked (so the
update below is bad and I need to redo it)
 https://bodhi.fedoraproject.org/updates/FEDORA-2020-9074133de4

In fact, trying to use %lua_requires does not seem to work, with and
without curly braces:

error: line 15: Unknown tag: %lua_requires
error: line 15: Unknown tag: %{lua_requires}

Could someone help explain these two behaviors? I'm working on resuming
the Lua packaging draft so I want to have a canonical example on how
the macros are supposed to be used.

PS Björn -- we should consider moving the macros out of lua-devel and
into lua-rpm-macros, that lua-devel then depends on. That will fix the
inability to get these macros out to EPEL6 and EPEL7 - on those, lua
packages can just BR the macro package directly.
