Relevant upstream changes:
- Sources were moved from trace-cmd repository to a new repository.
- Makefile for building documentation is broken. Therefore, we don't
build documentation. After upstream fixes it, we can build it again.
Besides updating trace-cmd, this commit also switches from bundled
libtraceevent and libtracefs to their external sources. Upstream
copied those libraries to separate repositories (see
https://lore.kernel.org/linux-trace-devel/20210325172357.6e059c31@gandalf.local.home/).
Another change relates to documentation building, which upstream
reworked. We disable HTML documentation - previous versions did not
provide it too.
Finally, we enable parallel build, which is simpler if `buildPhase` is
not overridden.
Besides updating the version, this commit decouples trace-cmd and
kernelshark source revisions. These two programs are developed in the
same repository but are released independently. Nixpkgs built the
previous versions of these programs from the same source commit, which
meant that at least one of the programs were not built from the
officially released version. Now we use the release tags of the
corresponding programs.
According to https://repology.org/repository/nix_unstable/problems, we have a
lot of packages that have http links that redirect to https as their homepage.
This commit updates all these packages to use the https links as their
homepage.
The following script was used to make these updates:
```
curl https://repology.org/api/v1/repository/nix_unstable/problems \
| jq '.[] | .problem' -r \
| rg 'Homepage link "(.+)" is a permanent redirect to "(.+)" and should be updated' --replace 's@$1@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
In line with the Nixpkgs manual.
A mechanical change, done with this command:
find pkgs -name "*.nix" | \
while read f; do \
sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
done
I manually skipped some:
* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)
Gets rid of this build error:
