This is still a WIP, everything here is subject to substantial change. It’s not review-ready at all, but if anyone’s interested, feel free to take a look and raise any questions or comments about the WIP code.

Current status:

draft implementation done for both preloading and dlopen
need to refactor the code structure wtih huge code cleanup
a lot of details need to be polished

Todo:

Integrate with Lind-boot
Add support for fork, threads, signal within the shared libraries

Closes #13
Closes #521
Closes #622
Closes #623

… approach

…627) * Add unified cargo compilation support. - Add cargo-lind_compile global binary - Add lind::epoch_callback in the linker * Remove trailing escape sequence * Add symlink to lind-cargo * Handle epoch_callback change in #631 * wasip1-clang.sh: Fix the REPO_ROOT, chmod +x * Update docs: compiling rust, getting started * Remove .DS_Store * Alias => lind-cargo-build * More detailed contrib docs

* fixed ignored signal interruption * added test for ignored signal interruption * fixed deterministic test * update signal documentation * removed printf in test * delete unused code

* Fix pointer translation in getsockopt syscall * Apply rustfmt formatting * Re-enable getsockopt tests after pointer translation fix

* Update Dockerfiles and Makefile for build and sysroot folder * update lind scripts for using new build/sysroot

* Convert pipeinput, pipeinput2, pipeonestring, and pipewrite to deterministic assert-based tests - Replace non-deterministic printf statements with assert() calls - Remove printing of PIDs, FD numbers, return values, and message contents - Add required assertions for pipe(), fork(), write(), read(), memcmp(), close(), and waitpid() - Ensure tests fail via assert() on incorrect behavior - Use fixed messages with explicit length checks - Child processes read until full message length is received - Parent processes verify child exit status via waitpid() Addresses issue #603: Deprecate non-deterministic tests * fix: assert * moved non deterministic to deterministic folder * updated skip test
