This hook was added to get reproducible bytecode. Because it was causing
issues it was disabled, but still kept as a dependency. Now the main
issue with bytecode reproducibility has been resolved by updating pip to
20.2.4, we remove this hook as a dependency.
If a package with Python code is not yet reproducible, one could add
this hook to `nativeBuildInputs`.
Before this change, a Dhall package like the Prelude would be
encoded as a record with one field per supported version. Then
downstream packages would specify which package to override
by selecting a different record field.
The problem with that approach is that it did not provide an
easy way to override a package to a version other than the default
ones supplied by Nixpkgs. Normally you would use the `.override`
method for this purpose, but the `override` method added by
`buildDhall{Directory,GitHub}Package` is clobbered by the
`override` method added by `callPackage` in
`./pkgs/top-level/dhall-packages.nix`.
The solution is to add a separate `.overridePackage` method which is
essentially the exact same as `.override`, except that it is no
longer clobbered by `callPackage`. This `.overridePackage` method
allows one to override the arguments supplied to
`buildDhall{Directory,GitHub}Package`, making it easier to specify
package versions outside of the ones supported by Nixpkgs..
This also includes a change to only build one (preferred) version of each
package (instead of multiple supported versions per package), in order to
minimize the maintenance burden for the Dhall package set.
If JIT support is built in to ruby, there's no choice other then to
leave this cc reference as is. removeReferencesToCC didn't do it's job
completely since some time ago. That's why it was practically redundant
- `lib/ruby/${version}/<platform>/rbconfig.rb` still referenced cc.
Removing this reference from
`lib/ruby/${version}/<platform>/rbconfig.rb` as well might lead to
breakage in some Gems that require this feature.
But, if JIT support is not desired, it should be safe enough to
completely remove all cc references, both in
lib/ruby/${version}/<platform>/rbconfig.rb and in $out/lib/libruby.so .
Hence now `rubyMinimal` has JIT support disabled and it has no
references at all to stdenv.cc.
with #99631 and #102693 merged, it's possible to bump the babashka
version again.
However recent versions of babashka depend on java11 features and I
spoke in Slack with the project lead and this java11 dependency will
exist going forward.
Now that we have community builds of graalvm landed in #99631, both
clj-kondo and babashka can depend on those versions of graalvm rather
than the one that requires building from source - this can be built in
hydra, and generally is much easier to build and test.
ext/io/console/io-console.gemspec was embedding a timestamp which made
the build not reproducible. Gems respect SOURCE_DATE_EPOCH so it's
enough to just delete that line if it exists.
This file has been fixed in
679a941d05 (diff-d8422f096931c58d4463e2489f62a228b0f24f0492950ba88c8c89a0d741cfe6)
And then ruby regularly merges that gem into their own repository. Ruby
master is fixed but none of the ruby releases have been fixed yet.
lib/ruby/gems/2.6.0/specifications/default/io-console-0.4.7.gemspec now
contains:
s.date = "1980-01-01"
I made a mistake merge. Reverting it in c778945806 undid the state
on master, but now I realize it crippled the git merge mechanism.
As the merge contained a mix of commits from `master..staging-next`
and other commits from `staging-next..staging`, it got the
`staging-next` branch into a state that was difficult to recover.
I reconstructed the "desired" state of staging-next tree by:
- checking out the last commit of the problematic range: 4effe769e2
- `git rebase -i --preserve-merges a8a018ddc0` - dropping the mistaken
merge commit and its revert from that range (while keeping
reapplication from 4effe769e2)
- merging the last unaffected staging-next commit (803ca85c20)
- fortunately no other commits have been pushed to staging-next yet
- applying a diff on staging-next to get it into that state
