All the programs provided by ncurses were being installed to the $dev
output, but several of them are intended for runtime use, e.g. to
operate on the running terminal. These user-facing programs are moved to
the $bin output.
Several packages referred to "${ncurses}/bin" or "${ncurses.dev}/bin" at
runtime; these paths are also updated to refer to "${ncurses.bin}/bin".
The strftime test fails with:
NZST-12NZDT,M9.5.0,M4.1.0/3: expected "1970-01-01 13:00:00 +1300 (NZDT)", got "1970-01-01 12:00:00 +1200 (NZST)"
The source in fact marks this test as "ahistorical", so the result on
Darwin might not be incorrect.

The patch no longer applies as it's applied in the 8.25 release.
While at it don't use FORCE_UNSAFE_CONFIGURE on ARM as I don't see why
it's needed and it works for me without it.
Build-tested GNU hello on ARMv7 and verified that this affect its hash
on i686.
This will probably be mandatory soon, and is a step in the right
direction. Removes the deprecated meta.version, and move some meta
sections to the end of the file where I should have put them in
the first place.
Fix numerous configuration files referring to ‘/usr’ and ‘/lib’.
Some paths were still ending up in ‘/nix/store/.../nix/store/...’,
despite some well-intended hacks meant to avoid that. Replace them
with other hacks. It's all very fragile and ugly, so snapper should
feel right at home.
Oh, and `snapper create-config ~` still won't actually *do*
anything, because D-Bus (#12452). Use `--no-dbus` and add files
to ‘/etc’ as long as it complains.
Only fair that I help maintain this mess.
Changes:
- Added german man page,
- added support for Grub2 and Grub4Dos MBR,
- added support for KolibriOS MBR and FAT32 boot record,
- added support for ReactOS MBR, FAT32 and FAT16 BR,
- added support for Rufus MBR,
- added experimental support for large sectors ( > 512),
- now possible to alter OEM ID of FAT and NTFS boot records.
- now possible to alter Windows Disk Signature in MBR.
This reduces diffoscope's closure size from 2470 MiB to 579 MiB by
leaving out some less crucial dependencies (like GHC and Free
Pascal). These can be re-enabled by turning on enableBloat.
additional changes:
- tmate now depends on external libmsgpack and libssh
- postPatch is no longer useful as it applied to embedded msgpack
- regular automake can now be used
added tldr to all-packages.nix
cleaned up style
added metadata
semicolons
didn't test on mac. removed platform
wrong types
fixed duplication of version
Currently the package is built with /var in $out/var. That fails when it
tries to create/write things at runtime (nix store is read-only).
Instead, tell it to use /var (global directory) and fixup the
installation phase so it doesn't touch /var (leave that for runtime).
This unbreaks the colord dbus service, which apparently is needed by
cups to create color profiles for printers.
This improves our Bundler integration (i.e. `bundlerEnv`).
Before describing the implementation differences, I'd like to point a
breaking change: buildRubyGem now expects `gemName` and `version` as
arguments, rather than a `name` attribute in the form of
"<gem-name>-<version>".
Now for the differences in implementation.
The previous implementation installed all gems at once in a single
derivation. This was made possible by using a set of monkey-patches to
prevent Bundler from downloading gems impurely, and to help Bundler
find and activate all required gems prior to installation. This had
several downsides:
* The patches were really hard to understand, and required subtle
interaction with the rest of the build environment.
* A single install failure would cause the entire derivation to fail.
The new implementation takes a different approach: we install gems into
separate derivations, and then present Bundler with a symlink forest
thereof. This has a couple benefits over the existing approach:
* Fewer patches are required, with less interplay with the rest of the
build environment.
* Changes to one gem no longer cause a rebuild of the entire dependency
graph.
* Builds take 20% less time (using gitlab as a reference).
It's unfortunate that we still have to muck with Bundler's internals,
though it's unavoidable with the way that Bundler is currently designed.
There are a number improvements that could be made in Bundler that would
simplify our packaging story:
* Bundler requires all installed gems reside within the same prefix
(GEM_HOME), unlike RubyGems which allows for multiple prefixes to
be specified through GEM_PATH. It would be ideal if Bundler allowed
for packages to be installed and sourced from multiple prefixes.
* Bundler installs git sources very differently from how RubyGems
installs gem packages, and, unlike RubyGems, it doesn't provide a
public interface (CLI or programmatic) to guide the installation of a
single gem. We are presented with the options of either
reimplementing a considerable portion Bundler, or patch and use parts
of its internals; I choose the latter. Ideally, there would be a way
to install gems from git sources in a manner similar to how we drive
`gem` to install gem packages.
* When a bundled program is executed (via `bundle exec` or a
binstub that does `require 'bundler/setup'`), the setup process reads
the Gemfile.lock, activates the dependencies, re-serializes the lock
file it read earlier, and then attempts to overwrite the Gemfile.lock
if the contents aren't bit-identical. I think the reasoning is that
by merely running an application with a newer version of Bundler, you'll
automatically keep the Gemfile.lock up-to-date with any changes in the
format. Unfortunately, that doesn't play well with any form of
packaging, because bundler will immediately cause the application to
abort when it attempts to write to the read-only Gemfile.lock in the
store. We work around this by normalizing the Gemfile.lock with the
version of Bundler that we'll use at runtime before we copy it into
the store. This feels fragile, but it's the best we can do without
changes upstream, or resorting to more delicate hacks.
With all of the challenges in using Bundler, one might wonder why we
can't just cut Bundler out of the picture and use RubyGems. After all,
Nix provides most of the isolation that Bundler is used for anyway.
The problem, however, is that almost every Rails application calls
`Bundler::require` at startup (by way of the default project templates).
Because bundler will then, by default, `require` each gem listed in the
Gemfile, Rails applications are almost always written such that none of
the source files explicitly require their dependencies. That leaves us
with two options: support and use Bundler, or maintain massive patches
for every Rails application that we package.
