This change (1) upgrades to OpenBSD's newer kernel ABIs, and (2)
modifies APE to have a read-only data segment. Doing this required
creating APE Loader v1.1, which is backwards and forwards compatible
with the previous version.
If you've run the following commands in the past to install your APE
Loader systemwide, then you need to run them again. Ad-hoc installations
shouldn't be impacted. It's also recommended that APE binaries be remade
after upgrading, since they embed old versions of the APE Loader.
ape/apeuninstall.sh
ape/apeinstall.sh
This change does more than just fix OpenBSD. The new loader is smarter
and more reliable. We're now able create much tinier ELF and Mach-O data
structures than we could before. Both APE Loader and execvpe() will now
normalize ambiguous argv[0] resolution the same way as the UNIX shell.
Badness with TLS linkage has been solved.
Fixes#826
Files beginning with "MZqFpD" are Actually Portable Executables,
which have a printf statement in the first 4096 bytes with octal
codes that specify the ELF header. APE also specifies `jartsr='`
as an alternative prefix, intended for binaries that do not want
to be identified as Windows executables. Like the \177ELF magic,
all these prefixes decode as x86 jump instructions that could be
used for 16-bit bootloaders or 32-bit / 64-bit flat executables.
Most importantly they provide a fallback path for Thompson shell
copmatible command interpreters, which do not require a shebang,
e.g. bash, zsh, fish, bourne, almquist, etc. Please note that in
order to meet the requirements of POSIX.1, the single quote must
be followed by a newline character, before any null bytes occur.
