The new skip for the dynamic linker introduced in
ccfd26ef14 ("bintools-wrapper: skip dynamic linker for static
binaries") includes a change in behaviour, previously the $link32
variable was checked using an arithmetic expression via (( )). This
returns zero if the output of the arithmetic expression is nonzero, i.e.
link32=1 would return zero and the if condition would be executed.
The code refactored this to use "$link32" = "0" which is incorrect in
this case, since we want this if conditional to run if $link32 is 1.
Small shell excerpt for clarity:
$ export link32=1
$ export cookie=1
$ if [[ "$cookie" = "1" ]] && (( "$link32" )); then echo "do some stuff"; fi;
do some stuff
$ if [[ "$cookie" = "1" && "$link32" = "0" ]]; then echo "do some stuff"; fi;
$
Change it to check for $link32 = "1", as the previous code did.
As @lopsided98 points out in #105305, since the hashes are now target
sensative, and until we find reason to actually care to test what they
are exactly, we are best just normalizing them away in the tests.
- Generate a link to the initramfs file with an appropriate file
extension, guessed based on the compressor by default
- Use correct metadata in u-boot images if generated, up to now this
was hardcoded to gzip and would silently generate an erroneous image
if another compressor was specified
- Document all the parameters
- Improve cross-building compatibility, by allowing passing either a
string as before, or a function taking a package set and returning the
path to a compressor in the "compressor" argument of the
function.
- Support more compression algorithms
- Place compressor executable function and arguments in passthru, for
reuse when appending initramfses

Originally this was meant to support other Windows versions than just
Windows XP, but before I actually got a chance to implement this I left
the project that I implemented this for.
The code has been broken for years now and I highly doubt anyone is
interested in resurrecting this (including me), so in order to make this
less of a maintenance burden for everybody, let's remove it.

Docker (via containerd) and the the OCI Image Configuration imply and
suggest, respectfully, that the architecture set in images matches those
of GOARCH in the Go Language document.
This changeset updates the implimentation of getArch in dockerTools to
return GOARCH values, to satisfy Docker.
Fixes: #106695
Currently we set dynamic-linker unconditionally. This breaks
however some static binaries i.e. rust binaries linked against musl.
There is no reason we should set an elf interpreter for static binaries
hence this is skipped if `-static` or `-static-pie` is either passed to
our cc or ld wrapper.
If I'm running an Emacs executable from emacsWithPackages as my main
programming environment, and I'm hacking on Emacs, or the Emacs
packaging in Nixpkgs, or whatever, I don't want the Emacs packages
from the wrapper to show up in the load path of that child Emacs. It
results in differing behaviour depending on whether the child Emacs is
run from Emacs or from, for example, an external terminal emulator,
which is very surprising.
To avoid this, pass another environment variable containing the
wrapper site-lisp path, and use that value to remove the corresponding
entry in EMACSLOADPATH, so it won't be propagated to child Emacsen.
An empty entry in EMACSLOADPATH gets filled with the default value.
This is presumably why the wrapper inserted a colon after the entry it
added for the dependencies. But this naive approach wasn't always
correct.
For example, if the user ran emacs with EMACSLOADPATH=foo, the wrapper
would insert the default value (by adding the trailing `:') even
though the user was trying to expressly opt out of it.
To do this correctly, here I've replaced makeWrapper with a bespoke
script that will actually parse the EMACSLOADPATH provided in the
environment (if given), and insert the wrapper's load path just before
the default value. If EMACSLOADPATH is given but contains no default
value, we respect that and don't add the wrapped dependencies at all.
If no EMACSLOADPATH is given, we insert the wrapped dependencies
before the default value, just like before. In this way, the wrapped
Emacs should now behave as if the wrapped dependencies were part of
Emacs's default load-path value.
Previously, meta wasn't being passed through at all, because it's
removed from args without being used anywhere. This made it so that
rcirc-menu wasn't being marked as broken even though it was supposed
to be.
This patch copies the meta handling from melpaBuild, including the
default home page (adapted for ELPA).
Use "find -exec" to strip rather than "find … | xargs …". The former
ensures that stripping is attempted for each file, whereas the latter
will stop stripping at the first failure. Unstripped files can fool
runtime dependency detection and bloat closure sizes.
