tar(1) on FreeBSD does not use standard output or input when the -f flag
is not provided. Instead, it defaults to /dev/sa0 on FreeBSD.
Make this tar invocation a bit more robust and explicitly tell tar(1) to
use standard output.
This is one of the issues discovered while porting Nix to FreeBSD. It has
been tested and committed locally to FreeBSD ports:
https://svnweb.freebsd.org/ports/head/sysutils/nix/Makefile?revision=550026&view=markup#l108
When running `nix build -L` it can be fairly hard to read the output if
the build program intentionally renders whitespace on the left. A
typical example is `g++` displaying compilation errors.
With this patch, the whitespace on the left is retained to make the log
more readable:
```
foo> no configure script, doing nothing
foo> building
foo> foobar.cc: In function 'int main()':
foo> foobar.cc:5:5: error: 'wrong_func' was not declared in this scope
foo> 5 | wrong_func(1);
foo> | ^~~~~~~~~~
error: --- Error ------------------------------------------------------------------------------------- nix
error: --- Error --- nix-daemon
builder for '/nix/store/i1q76cw6cyh91raaqg5p5isd1l2x6rx2-foo-1.0.drv' failed with exit code 1
```
The registry targets generally follow a URL formatting schema with
support for a query parameter of "?dir=subpath" to specify a sub-path
location below the URL root.
Alternatively, an absolute path can be specified. This specification
mode accepts the query parameter but ignores/drops it. It would
probably be better to either (a) disallow the query parameter for the
path form, or (b) recognize the query parameter and add to the path.
This patch implements (b) for consistency, and to make it easier for
tooling that might switch between a remote git reference and a local
path reference.

This change provides support for using access tokens with other
instances of GitHub and GitLab beyond just github.com and
gitlab.com (especially company-specific or foundation-specific
instances).
This change also provides the ability to specify the type of access
token being used, where different types may have different handling,
based on the forge type.
std::optional had redundant checks for whether it had a value.
An object is emplaced either way so it can be dereferenced
without repeating a value check
After 0ed946aa61, max-jobs setting (-j/--max-jobs)
stopped working.
The reason was that nrLocalBuilds (which compared to maxBuildJobs to figure
out whether the limit is reached or not) is not incremented yet when tryBuild
is started; So, the solution is to move the check to tryLocalBuild.
Closes https://github.com/nixos/nix/issues/3763
We don't need it yet, but we could/should in the future, and it's a
cost-free change since we already have the reference. I like it.
