# SYNOPSIS
#
# Cosmopolitan Core Build Definitions
#
# DESCRIPTION
#
# Nearly all compiler flag tuning is done within this one file. Flags
# may be customized with environment variables. We also use this file
# to compute expensive values once per build.
#
# When tuning the variables below, please note they're interpreted in
# the strictest sense. For example, we don't pass CFLAGS to gcc if we

# know it's compiling a .S file. This enables our `make V=0` logging
# to be succinct and informative at the cost of being less forgiving.

#
# Further note that link order is equally unforgiving in repositories
# of this scale. We approach that by over-specifying dependencies, in
# packages that're broken down usually on a per-directory basis. This
# is aided by the checkdeps and functional programming tools which in
# most cases should be able to deduce correct ordering automatically.
#
# Concerning our approach to flag tuning, most of it is non-essential
# and largely serves to turn features off. Particularly features that
# would otherwise lock us in to a particular platform or legal terms.
# Other flags will usually be the ones that provide us marginal gains
# in terms of performance and code size, but the world won't end when
# they aren't used. Flags that play a critical role in source working

Set LC_ALL=C in build config (#43) It's most likely the case (and SHOULD be the case) that C is the same locale as C.UTF-8. The only exception might be Python's gonzo unicode handling which whines when unicode is used without authorization, but that shouldn't be an issue since we don't need Python to build.

Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Rewrite .zip.o file linker This change takes an entirely new approach to the incremental linking of pkzip executables. The assets created by zipobj.com are now treated like debug data. After a .com.dbg is compiled, fixupobj.com should be run, so it can apply fixups to the offsets and move the zip directory to the end of the file. Since debug data doesn't get objcopy'd, a new tool has been introduced called zipcopy.com which should be run after objcopy whenever a .com file is created. This is all automated by the `cosmocc` toolchain which is rapidly becoming the new recommended approach. This change also introduces the new C23 checked arithmetic macros.

PECHECK = build/bootstrap/pecheck.com
Prove that Makefile is fully defined The whole repository is now buildable with GNU Make Landlock sandboxing. This proves that no Makefile targets exist which touch files other than their declared prerequisites. In order to do this, we had to: 1. Stop code morphing GCC output in package.com and instead run a newly introduced FIXUPOBJ.COM command after GCC invocations. 2. Disable all the crumby Python unit tests that do things like create files in the current directory, or rename() files between folders. This ended up being a lot of tests, but most of them are still ok. 3. Introduce an .UNSANDBOXED variable to GNU Make to disable Landlock. We currently only do this for things like `make tags`. 4. This change deletes some GNU Make code that was preventing the execve() optimization from working. This means it should no longer be necessary in most cases for command invocations to be indirected through the cocmd interpreter. 5. Missing dependencies had to be declared in certain places, in cases where they couldn't be automatically determined by MKDEPS.COM 6. The libcxx header situation has finally been tamed. One of the things that makes this difficult is MKDEPS.COM only wants to consider the first 64kb of a file, in order to go fast. But libcxx likes to have #include lines buried after huge documentation. 7. An .UNVEIL variable has been introduced to GNU Make just in case we ever wish to explicitly specify additional things that need to be whitelisted which aren't strictly prerequisites. This works in a manner similar to the recently introduced .EXTRA_PREREQS feature. There's now a new build/bootstrap/make.com prebuilt binary available. It should no longer be possible to write invalid Makefile code.

Make improvements - We now serialize the file descriptor table when spawning / executing processes on Windows. This means you can now inherit more stuff than just standard i/o. It's needed by bash, which duplicates the console to file descriptor #255. We also now do a better job serializing the environment variables, so you're less likely to encounter E2BIG when using your bash shell. We also no longer coerce environ to uppercase - execve() on Windows now remotely controls its parent process to make them spawn a replacement for itself. Then it'll be able to terminate immediately once the spawn succeeds, without having to linger around for the lifetime as a shell process for proxying the exit code. When process worker thread running in the parent sees the child die, it's given a handle to the new child, to replace it in the process table. - execve() and posix_spawn() on Windows will now provide CreateProcess an explicit handle list. This allows us to remove handle locks which enables better fork/spawn concurrency, with seriously correct thread safety. Other codebases like Go use the same technique. On the other hand fork() still favors the conventional WIN32 inheritence approach which can be a little bit messy, but is *controlled* by guaranteeing perfectly clean slates at both the spawning and execution boundaries - sigset_t is now 64 bits. Having it be 128 bits was a mistake because there's no reason to use that and it's only supported by FreeBSD. By using the system word size, signal mask manipulation on Windows goes very fast. Furthermore @asyncsignalsafe funcs have been rewritten on Windows to take advantage of signal masking, now that it's much more pleasant to use. - All the overlapped i/o code on Windows has been rewritten for pretty good signal and cancelation safety. We're now able to ensure overlap data structures are cleaned up so long as you don't longjmp() out of out of a signal handler that interrupted an i/o operation. Latencies are also improved thanks to the removal of lots of "busy wait" code. Waits should be optimal for everything except poll(), which shall be the last and final demon we slay in the win32 i/o horror show. - getrusage() on Windows is now able to report RUSAGE_CHILDREN as well as RUSAGE_SELF, thanks to aggregation in the process manager thread.

Restore zip.com and .symtab files This change restores the .symtab symbol table files in our flagship programs (e.g. redbean.com, python.com) needed to show backtraces. This also rolls back earlier changes to zip.com w.r.t. temp directories since the right way to do it turned out to be the -b DIR flag. This change also improves the performance of zip.com. It turned out mmap() wasn't being used, because zip.com was assuming a 4096-byte granularity, but cosmo requires 65536. There was also a chance to speed up stdio scanning using the unlocked functions.

Improve memory safety This commit makes numerous refinements to cosmopolitan memory handling. The default stack size has been reduced from 2mb to 128kb. A new macro is now provided so you can easily reconfigure the stack size to be any value you want. Work around the breaking change by adding to your main: STATIC_STACK_SIZE(0x00200000); // 2mb stack If you're not sure how much stack you need, then you can use: STATIC_YOINK("stack_usage_logging"); After which you can `sort -nr o/$MODE/stack.log`. Based on the unit test suite, nothing in the Cosmopolitan repository (except for Python) needs a stack size greater than 30kb. There are also new macros for detecting the size and address of the stack at runtime, e.g. GetStackAddr(). We also now support sigaltstack() so if you want to see nice looking crash reports whenever a stack overflow happens, you can put this in main(): ShowCrashReports(); Under `make MODE=dbg` and `make MODE=asan` the unit testing framework will now automatically print backtraces of memory allocations when things like memory leaks happen. Bugs are now fixed in ASAN global variable overrun detection. The memtrack and asan runtimes also handle edge cases now. The new tools helped to identify a few memory leaks, which are fixed by this change. This change should fix an issue reported in #288 with ARG_MAX limits. Fixing this doubled the performance of MKDEPS.COM and AR.COM yet again.

Fully support OpenBSD 7.3 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

Prove that Makefile is fully defined The whole repository is now buildable with GNU Make Landlock sandboxing. This proves that no Makefile targets exist which touch files other than their declared prerequisites. In order to do this, we had to: 1. Stop code morphing GCC output in package.com and instead run a newly introduced FIXUPOBJ.COM command after GCC invocations. 2. Disable all the crumby Python unit tests that do things like create files in the current directory, or rename() files between folders. This ended up being a lot of tests, but most of them are still ok. 3. Introduce an .UNSANDBOXED variable to GNU Make to disable Landlock. We currently only do this for things like `make tags`. 4. This change deletes some GNU Make code that was preventing the execve() optimization from working. This means it should no longer be necessary in most cases for command invocations to be indirected through the cocmd interpreter. 5. Missing dependencies had to be declared in certain places, in cases where they couldn't be automatically determined by MKDEPS.COM 6. The libcxx header situation has finally been tamed. One of the things that makes this difficult is MKDEPS.COM only wants to consider the first 64kb of a file, in order to go fast. But libcxx likes to have #include lines buried after huge documentation. 7. An .UNVEIL variable has been introduced to GNU Make just in case we ever wish to explicitly specify additional things that need to be whitelisted which aren't strictly prerequisites. This works in a manner similar to the recently introduced .EXTRA_PREREQS feature. There's now a new build/bootstrap/make.com prebuilt binary available. It should no longer be possible to write invalid Makefile code.

Rewrite .zip.o file linker This change takes an entirely new approach to the incremental linking of pkzip executables. The assets created by zipobj.com are now treated like debug data. After a .com.dbg is compiled, fixupobj.com should be run, so it can apply fixups to the offsets and move the zip directory to the end of the file. Since debug data doesn't get objcopy'd, a new tool has been introduced called zipcopy.com which should be run after objcopy whenever a .com file is created. This is all automated by the `cosmocc` toolchain which is rapidly becoming the new recommended approach. This change also introduces the new C23 checked arithmetic macros.

Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html
