This combines the *.o into a big .o producing one translation unit.
This preserve our unused static initializers, as specified in the C++
standard:
If no variable or function is odr-used from a given translation
unit, the non-local variables defined in that translation unit may
never be initialized (this models the behavior of an on-demand
dynamic library).
Note that this is very similar to how the --whole-archive flag works.
One advantage of this is that users of the final .a library don’t have
to worry about specifying --whole-archive, or that we have unused
static initializers at all!
bool coerces anything >0 to true, but in the future we may have other
file ingestion methods. This shows a better error message when the
“recursive” byte isn’t 1.
As `git fetch` may chose to interpret refspec to it's liking, ensure that we
only pass refs that begin with `refs/` as is, otherwise, prepend them with
`refs/heads`. Otherwise, branches named `heads/foo` (I know it's bad, but it's
allowed), would be fetched as `foo`, instead of `heads/foo`.
The previous regex was too strict and did not match what git was allowing. It
could lead to `fetchGit` not accepting valid branch names, even though they
exist in a repository (for example, branch names containing `/`, which are
pretty standard, like `release/1.0` branches).
The new regex defines what a branch name should **NOT** contain. It takes the
definitions from `refs.c` in https://github.com/git/git and `git help
check-ref-format` pages.
This change also introduces a test for ref name validity checking, which
compares the result from Nix with the result of `git check-ref-format --branch`.
The idea is it's always more flexible to consumer a `Source` than a
plain string, and it might even reduce memory consumption.
I also looked at `addToStoreFromDump` with its `// FIXME: remove?`, but
the worked needed for that is far more up for interpretation, so I
punted for now.
On macOS the system tar has builtin support for lzma while xz isn't
available as a separate binary. There's no builtin package manager
there available either so having to install lzma (without nix) would be
rather painful.
This moves the actual parsing of configuration contents into applyConfig
which applyConfigFile is then going to call. By changing this we can now
test the configuration file parsing without actually create a file on
disk.
Since the binary tarball was replaced none of the hydra builds include
the manual. The dist phase isn't enabled by default the manual build
products where not written.
