This allows the progress bar to display "building perl-5.22.3" instead
of "building /nix/store/<hash>-perl-5.22.3.drv".

Besides being unused, this function has a bug that it will incorrectly
decode the path component Ubuntu\04016.04.2\040LTS\040amd64 as
"Ubuntu.04.2 LTS amd64" instead of "Ubuntu 16.04.2 LTS amd64".

This replaces "nix-store --optimise". Main difference is that it has a
progress indicator.

They're the same thing after all.
Example:
$ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped
[0/1 built, 49/98 copied, 16.3/92.8 MiB DL, 55.8/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/0pl9li1jigcj2dany47hpmn0r3r48wc4nz48v5mqhh426lgz3bz6.nar.xz'
|
|
E.g.
$ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped
[0/1 built, 1/97/98 fetched, 65.8/92.8 MiB DL, 203.2/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/1czm9fk0svacy4h6a3fzkpafi4f7a9gml36kk8cq1igaghbspg3k.nar.xz'

It now shows the amount of data copied:

Issue #1506.

This is needed to get Nix compiled using Android NDK.

except in older release notes where the name was actually Mac OS X.

The package list is now cached in
~/.cache/nix/package-search.json. This gives a substantial speedup to
"nix search" queries. For example (on an SSD):
First run: (no package search cache, cold page cache)
$ time nix search blender
Attribute name: nixpkgs.blender
Package name: blender
Version: 2.78c
Description: 3D Creation/Animation/Publishing System
real 0m6.516s
Second run: (package search cache populated)
$ time nix search blender
Attribute name: nixpkgs.blender
Package name: blender
Version: 2.78c
Description: 3D Creation/Animation/Publishing System

Fixes #1464.
|
|
Not really necessary anymore for #849, but still nice to have.
|
|
Fix potential crash/wrong result two hashes of unequal length are compared
|
|
Also simplify the Hash API.
Fixes #1437.

Thus, instead of ‘--option <name> <value>’, you can write ‘--<name>
<value>’. So
--option http-connections 100
becomes
--http-connections 100
Apart from brevity, the difference is that it's not an error to set a
non-existent option via --option, but unrecognized arguments are
fatal.
Boolean options have special treatment: they're mapped to the
argument-less flags ‘--<name>’ and ‘--no-<name>’. E.g.
--option auto-optimise-store false
becomes
--no-auto-optimise-store

This caused "nix-store --import" to compute an incorrect hash on NARs
that don't fit in an unsigned int. The import would succeed, but
"nix-store --verify-path" or subsequent exports would detect an
incorrect hash.
A deeper issue is that the export/import format does not contain a
hash, so we can't detect such issues early.
Also, I learned that -Wall does not warn about this.

this fixes a linker failure on cygwin 64 due to some bad
interaction between tls and shared libraries.

In particular, show descriptions. This could be used for manpage
generation etc.

This makes all config options self-documenting.
Unknown or unparseable config settings and --option flags now cause a
warning.
|

The typical use is to inherit Config and add Setting<T> members:
class MyClass : private Config
{
Setting<int> foo{this, 123, "foo", "the number of foos to use"};
Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"};
MyClass() : Config(readConfigFile("/etc/my-app.conf"))
{
std::cout << foo << "\n"; // will print 123 unless overriden
}
};
Currently, this is used by Store and its subclasses for store
parameters. You now get a warning if you specify a non-existant store
parameter in a store URI.
