The `ape-no-modify-self.o` bootloader now has an mmap-based
payload that helps read-only APE binaries be load faster since it
doesn't need to copy any files.
This change reinvents all the GNU Readline features I discovered that I
couldn't live without, e.g. UTF-8, CTRL-R search and CTRL-Y yanking. It
now feels just as good in terms of user interface from the subconscious
workflow perspective. It's real nice to finally have an embeddable line
reader that's actually good with a 30 kb footprint and a bsd-2 license.
This change adds a directory to the examples folder, explaining how the
new Python compiler may be used. Some of the bugs with Python binaries
have been addressed but overall it's still a work in progress.
qjsc.com now has a -n do nothing flag so the makefile can create a
localized binary. See also #267 where we have an exciting new change
aiming to address this particular APE gotcha.
- Compile repl.js & qjscalc.js and include them in qjs.com zip
- Change quickjs-libc.c / js_os_poll to handle Windows console
This last change is needed because poll and select on Windows forbid
non-socket handles and Cosmopolitan Libc hasn't polyfilled that yet.
We can now link even smaller Python binaries. For example, the hello.com
program in the Python build directory is a compiled linked executable of
hello.py which just prints hello world. Using decentralized sections, we
can make that binary 1.9mb in size (noting that python.com is 6.3 megs!)
This works for nontrivial programs too. For example, say we want an APE
binary that's equivalent to python.com -m http.server. Our makefile now
builds such a binary using the new launcher and it's only 3.2mb in size
since Python sources get turned into ELF objects, which tell our linker
that we need things like native hashing algorithm code.
The termios::c_cc field turned out to be incorrectly defined on Linux
due to some confusion between the glibc and kernel definitions. We'll
be using the kernel definition, since it has the strongest consensus.
Fields have been have been added to struct stat for BSD compatibility
such as st_birthtim, plus the GLIBC compatibility of isystem/sys/stat
has been improved.
This breaking change improves naming consistency.
- Rename LOGF to INFOF
- Rename recently introduced ANYF to LOGF
- Remove V* log calls, as they are not being used
The ZIP filesystem has a breaking change. You now need to use /zip/ to
open() / opendir() / etc. assets within the ZIP structure of your APE
binary, instead of the previous convention of using zip: or zip! URIs.
This is needed because Python likes to use absolute paths, and having
ZIP paths encoded like URIs simply broke too many things.
Many more system calls have been updated to be able to operate on ZIP
files and file descriptors. In particular fcntl() and ioctl() since
Python would do things like ask if a ZIP file is a terminal and get
confused when the old implementation mistakenly said yes, because the
fastest way to guarantee native file descriptors is to dup(2). This
change also improves the async signal safety of zipos and ensures it
doesn't maintain any open file descriptors beyond that which the user
has opened.
This change makes a lot of progress towards adding magic numbers that
are specific to platforms other than Linux. The philosophy here is that,
if you use an operating system like FreeBSD, then you should be able to
take advantage of FreeBSD exclusive features, even if we don't polyfill
them on other platforms. For example, you can now open() a file with the
O_VERIFY flag. If your program runs on other platforms, then Cosmo will
automatically set O_VERIFY to zero. This lets you safely use it without
the need for #ifdef or ifstatements which detract from readability.
One of the blindspots of the ASAN memory hardening we use to offer Rust
like assurances has always been that memory passed to the kernel via
system calls (e.g. writev) can't be checked automatically since the
kernel wasn't built with MODE=asan. This change makes more progress
ensuring that each system call will verify the soundness of memory
before it's passed to the kernel. The code for doing these checks is
fast, particularly for buffers, where it can verify 64 bytes a cycle.
- Correct O_LOOP definition on NT
- Introduce program_executable_name
- Add ASAN guards to more system calls
- Improve termios compatibility with BSDs
- Fix bug in Windows auxiliary value encoding
- Add BSD and XNU specific errnos and open flags
- Add check to ensure build doesn't talk to internet
