Remove UnicodeCollate dependency, which is part of Perl 5.28 and
does not exist separately anymore.
Add PerlIO::utf8_strict, which lack thereof Biber complains about
during build.
This introduces extra escaping for $NIX_STORE that gets interpolated
into a PCRE. The escaping is performed using a standard Perl function
"quotemeta" (see "perldoc -f quotemeta" for reference). The same value
is also used in sed regex which uses POSIX basic regular expressions
instead of PCRE, so it needs fewer characters to be escaped. It should
not cause much problem to not change sed invocation, but I replace it
with equivalent Perl expression (actually the behavior is changed to not
output a newline character after the matched output).
Update bpftrace to the latest pre-release, with a real version number.
The most notable change now is that bpftrace can use a stable version of
the 'bcc' toolchain in order to build, meaning no more hacks are needed
to clone the source code and fix up the build system, etc. This
simplifies things greatly and removes the old bcc-source patch.
Similarly, we can remove our custom gtests patch (which disabled the
build) by just passing -DBUILD_TESTING=FALSE when running cmake. This
was also added upstream recently.
However, something does still need to be fixed, at a cost: bpftrace
requires the kernel -dev package because it wants both objects and
include directories (some files are only shipped in one or the other).
Therefore, we remove the dependency on linuxHeaders and instead use
kernel.dev as the sole input to the build.
This is both a positive and a negative: the positive is that tools work
without annoying fatal errors, and that the bpf toolchain is
synchronized to the linuxPackages.kernel derivation it was built
against. The downside is that the .dev expression is much heavier as a
dependency, so bpftrace is now closer to 700mb in closure size. (This
especially hurts across kernel upgrades requiring a whole new rebuild,
especially if you have existing nixos generations that won't GC, etc.)
We probably want to slim this down substantially in the future (and
there may be a few ways to do that), but as this will probably also
touch bcc, and as a first cut of the pre-releases, this is probably fine
while we work out other kinks.
