2) fedpkg would not be needed if rpmbuild would be sanely able to do
something like `fedpkg --release master srpm` but even so basic think
requires either shuffling with files on FS or specifying million of
working directories. I really don't understand why this was never
improved.

Actually, this can be improved very easy in $HOME/.rpmmacros. I use
this:
%_topdir      %(echo $HOME)/build
%_sourcedir   %{_topdir}/SOURCES/%{name}
%_specdir     %{_sourcedir}
%_srcrpmdir   %{_rpmdir}

[quotation fixed]

Yup. If you prefer working in a dist-git like layout, just configure
rpm do behave that way. One possibility is simply:

%_topdir    %{getenv:PWD}
%_sourcedir    %{_topdir}
%_specdir    %{_topdir}
%_srcrpmdir    %{_topdir}
%_builddir    %{_topdir}

..and perhaps %_buildrootdir as well. And then just "mkdir foo; cd
foo" when starting a new package.

I didn't say anything about everybody or needing to do, I said if YOU prefer that layout, configure accordingly.

It is simple when it's five line copy-paste you only do once.


The reasons that rpm doesn't default to this directory per source
package layout include
- there are cases where this doesn't work so well
- it'd invalidate 20+ years of documentation on the subject
- nobody has sat down to figure how to transition the existing
assumptions to this type of layout without breaking everybodys setup
in the progress


It would be nice if rpmbuild tried some small heuristic to figure out
the layout. E.g. if it fails to build SRPM because of missing sources,
try to locate the sources at current directory. This does not look that
hard. Nobody would miss the `--define "_sourcedir `pwd`"`.

Nope. Rpm cannot go looking around the filesystem for stuff that isn't there, otherwise the result becomes unreliable and unreproducable.

Look, I'm no more in love with the traditional layout than anybody, I'm just saying changing the default is not as simple as you'd like to think. Anybody wanting to work on changing the default is welcome to propose it upstream, patches welcome and all.
