This makes it consistent with the Nixpkgs fetchurl and makes it work
in chroots. We don't need verification because the hash of the result
is checked anyway.
The stack allocated for the builder was way too small (32 KB). This is
sufficient for normal derivations, because they just do some setup and
then exec() the actual builder. But for the fetchurl builtin
derivation it's not enough. Also, allocating the stack on the caller's
stack was fishy business.
If keywords are matched on the start/end of words then
keywords are also matched if they are surrounded by dashes
or underscores. For example the keyword with is highlighted
in geany-with-vte. When matching on the start/end of symbols
the keyword is only highlighted if it is not part of an other
identifier.
This allows overriding the name component of the resulting Nix store
path, which is necessary if the base name of the URI contains
"illegal" characters.
This is in particular useful for fetchFromGitHub et al., ensuring that
the store path produced by nix-prefetch-url corresponds to what those
functions expect.
This allows nix-prefetch-url to prefetch the output of fetchzip and
its wrappers (like fetchFromGitHub). For example:
$ nix-prefetch-url --unpack https://github.com/NixOS/patchelf/archive/0.8.tar.gz
or from a Nix expression:
$ nix-prefetch-url -A nix-repl.src
In the latter case, --unpack can be omitted because nix-repl.src is a
fetchFromGitHub derivation and thus has "outputHashMode" set to
"recursive".
Some evidence that defining it to be 0 is right:
* OS X headers define it to be 0.
* Other code uses 0 instead of SOL_LOCAL to check for peer credentials
(e.g. FreeBSD's implementation of getpeereid).
Previously, pkg-config was already queried for libsqlite3's and
libcurl's link flags. However they were not used, but hardcoded
instead. This commit replaces the hardcoded LDFLAGS by the ones
provided by pkg-config in a similar pattern as already used for
libsodium.
For example,
$ nix-prefetch-url -A hello.src
will prefetch the file specified by the fetchurl call in the attribute
‘hello.src’ from the Nix expression in the current directory. This
differs from ‘nix-build -A hello.src’ in that it doesn't verify the
hash.
You can also specify a path to the Nix expression:
$ nix-prefetch-url ~/Dev/nixpkgs -A hello.src
List elements (typically used in ‘patches’ attributes) also work:
$ nix-prefetch-url -A portmidi.patches.0
