This cuts the kernel provide generation time from ~33s to 2.5s on my laptop.
Tighten the path matching rule a bit while at it - it doesn't matter that
much with parametric generator but there's no point looking at entries
we don't generate dependencies on.
Resolves: rhbz#1595265
The problem this change is intended to solve is with how `real_libdir`
is calculated. Let's assume we want to recursively byte-compile all
`*.py` files in
`/builddir/build/BUILDROOT/python-scales-1.0.9-250.fc32.x86_64/usr/lib/python3.8`.
Then, `real_libdir` is this path without `$RPM_BUILD_ROOT` with
the filename at the end which displays in the error message like this:
```
Bytecompiling .py files below /builddir/build/BUILDROOT/python-scales-1.0.9-250.fc32.x86_64/usr/lib/python3.8 using /usr/bin/python3.8
*** Error compiling '/builddir/build/BUILDROOT/python-scales-1.0.9-250.fc32.x86_64/usr/lib/python3.8/site-packages/greplin/bar.py'...
File "/usr/lib/python3.8/bar.py", line 1
import sin from math
^
SyntaxError: invalid syntax
```
`/usr/lib/python3.8/bar.py` is obviously wrong.
One of the new features of the `compileall2` module (which will
be available in stdlib in Python 3.9) is that the path byte-compiled to
`*.pyc` files is calculated for each file. This means that by using
`-s` and `-p` we can strip `$RPM_BUILD_ROOT` and prepend `/` for each
file individually which will fix the problem.

This change has an effect only for Python >= 3.4.
If %source_date_epoch_from_changelog is true, RPM can set the SOURCE_DATE_EPOCH
environment variable to the timestamp of the topmost changelog entry. The
SOURCE_DATE_EPOCH can be in turn used by various projects to override otherwise
dynamically generated timestamps.
E.g. this might help to have stable timestamps in generated
documentation etc.
Rpm 4.15 removes various language-specific macros. Python side is
already covered by the versioned python macros but this is not the
case with Perl, macros. Add them here temporarily to avoid breaking
the world, but these really belong to perl-macros or such.
Once upon a time these did differ (for various bad reasons) but the
version in rpm has been identical to ours for many years, lets shed
some old baggage.
– permit extraction of multiple archives in a single specfile
– %forgemeta, %forgesetup, %forgeautosetup: add a “-z <number>” switch to
select a specific set of rpm variables
(for example forgeurl<number> and version<number>)
– %forgemeta, %forgesetup: add a “-a” switch to process all sets in one go
(makes no sense in forgeautosetup, as you need so select specific patches)
– %forgemeta: deprecate the “-u” switch, use “-z” it’s better
(“-u” was awkward and mainly used by the %gometa macro. %gometa will now
call the lua code directly)
– %forgesetup: use “-v” for verbose processing, be quiet by default, drop “-q”
(align with %forgemeta, %forgeautosetup and %autosetup)
– %forgesetup, %forgeautosetup: only pass flags that make sense to
%setup/%autosetup; reorder to match what works in el7
– factor out complex or common lua code in separate lua modules, to allow:
– code reuse in other macros without cut and pasting
– direct lua routine invocation from other macros without going through a
rpm macro
– rpm syntax errors that point to a line in an actual lua file
– %forgemeta: refactor the logic to drop as much forge-specific code as
possible, use a single logic flow with tables of constants
– %forgemeta: export more computed info in rpm variables, such as the
%{_builddir} subdirectory an archive was extracted to (lifesaver when
processing multiple archives)
– %forgemeta: prepend secondary distprefixes with .S, to make clear they do
not apply to the main archive
– %forgemeta: add versionx to secondary distprefixes, if relevant
– %forgemeta: make tar.bz2 the default archive format
Caveats:
– forge services implement full-release downloads via tags. However the actual
syntax of such tags is not standardised. If the macro does not guess the
correct tag an upstream uses for a specific release, you will need to
set the tag value explicitly.
– GitHub lets upstreams move their projects to new URLs, keeping the old URL
active. It all works transparently *except* the top directory inside
generated archives always matches the new project name (even when accessed
by compatibility URLs, and even for releases that antedate the renaming).
Therefore, if macro processing of a GitHub archive suddenly fails, start by
checking if upstream didn’t rename itself.
Multicall usage example (with “-a”)
– to process a specific bloc in one of the macros use “-z <suffix>”
– suffix 0 and no suffix are synonyms
– therefore, calling the macros without “-a” or “-z” just works for the
general use case when you have a single archive to process
– caveat: forge services implement full-release
