The "no modify self" variant of Actually Portable Executable is now
supported on all platforms. If you use `$(APE_NO_MODIFY_SELF)` then
ld.bfd will embed a 4096 byte ELF binary and a 4096 byte Macho file
which are installed on the fly to ${TMPDIR:-/tmp}, which enables us
launch the executable, without needing to copy the whole executable
To prevent it from copying a tiny executable to your temp directory
you need to install the `ape` command (renamed from ape-loader), to
a system path. For example:
# FreeBSD / NetBSD / OpenBSD
make -j8 o//ape/ape
cp o//ape/ape /usr/bin/ape
# Mac OS
# make -j8 o//ape/ape.macho
curl https://justine.lol/ape.macho >/usr/bin/ape
chmod +x /usr/bin/ape
On Linux you can get even more performance with the new binfmt_misc
support which makes launching non-modifying APE binaries as fast as
launching ELF executables. Running the following command:
# Linux
ape/apeinstall.sh
Will copy APE loader to /usr/bin/ape and register with binfmt_misc
Lastly, this change also fixes a really interesting race condition
with OpenBSD thread joining.
