- the default --docdir is typically DATAROOTDIR/doc/pkgName
- I saw no other way than to employ some magic to guess this `pkgName`
- user can override it by setting $shareDocName
I supplied meta.outputsToInstall automatically in all
mkDerivation products, but some packages still don't use it.
The reported case: jekyll -> bundlerEnv -> buildEnv -> runCommand.
There were two sources of non-determinisim coming into the images. The
first was tar mtimes, the second was pigz/gzip times.
An example image now passes with the --check flag.
I think the intention of this functionality was to provide a simple
alternative to the "runAsRoot" and "contents" attributes.
The implementation caused very slow builds of Docker images. Almost all
of the build time was spent in IO for tar, due to tarballs being
created, immediately extracted, then recreated. I had 30 minute builds
on some of my images which are now down to less than 2 minutes. A couple
of other users on #nix IRC have observed similar improvements.
The implementation also mutated the produced Docker layers without
changing their hashes. Using non-empty tarballs would produce images
which got cached incorrectly in Docker.
I have a commit which just fixes the performance problem but I opted to
completely remove the tarball feature after I found out that it didn't
correctly implement the Docker Image Specification due to the broken
hashing.
This is to avoid unwanted side effects when installing a wrapped emacs in the environment:
* All executables in the dependencies become available in the user environment
* All site-lisp binaries in the dependencies become accessible to unwrapped emacs
Also, both bin and site-lisp would generate conflicts so installing a wrapped emacs becomes really cumbersome
1. Update bower2nix version and add new/updated dependencies into
node-packages-generated.nix. This was done manually, with npm2nix
generating the initial set of derivations. In future, it would be
nice to have an automatic process (see #10358, #9332).
2. Add an override to nodePackages.bower2nix wrapping the commands so
that git is on the PATH.
3. Update fetchbower to support new command-line options of bower2nix,
and to allow github URL tag versions.
Previously, nix-prefetch-git would report the same JSON whether submodules were being fetched or not; with this change, the --fetch-submodules option will cause the JSON output to include "fetchSubmodules": true, so that fetchgit (builtins.fromJSON (builtins.readFile ./path/to/output.json)) will work.
