The `cosmocc` compiler is now being distributed as a self-contained
toolchain that's path-agnostic and it no longer requires you clone the
Cosmop repo to use it. The bin/ folder has been deleted from the mono
repo. The `fatcosmocc` command has been renamed to `cosmocc`. MacOS
support now works very well.
This new script is an alternative to the `cosmocc` command. It's still a
work in progress. It abstracts all the gory details of building separate
copies of your executable and then running the apelink.com program.
This change ports APE Loader to Linux AARCH64, so that Raspberry Pi
users can run programs like redbean, without the executable needing
to modify itself. Progress has also slipped into this change on the
issue of making progress better conforming to user expectations and
industry standards regarding which symbols we're allowed to declare
This change also incorporates more bug fixes and improvements to a wide
variety of small things. For example this fixes#860 so Windows console
doesn't get corrupted after exit. An system stack memory map issue with
aarch64 has been fixed. We no longer use O_NONBLOCK on AF_UNIX sockets.
Crash reports on Arm64 will now demangle C++ symbols, even when c++filt
isn't available. Most importantly the Apple M1 version of APE Loader is
brought up to date by this change. A prebuilt unsigned binary for it is
being included in build/bootstrap/. One more thing: retrieving the term
dimensions under --strace was causing the stack to become corrupted and
now that's been solved too. PSS: We're now including an ELF PT_NOTE for
APE in the binaries we build, that has the APE Loader version.
This version has better error messages and safety checks. It supports
loading static position-independent executables. It correctly handles
more kinds of weird ELF program header layouts. A force flag has been
added to avoid system execve(). Finally the longstanding misalignment
with our ELF PT_NOTE section has been addressed.
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.
