- Removed several commented out lines, from a failed attempted to draw ASCII art. The lines in question were in the _start function on src/main.rs.
- Removed the message that was displayed when the kernel was loaded successfully.
- Introduced a breakpoint exception to the _start function of src/main.rs.
- Added a message to notify the user of the kernel preventing a crash, due to the newly-added breakpointe exception (see _start, src/main.rs).
- Implemented a call to init, in the test _start function of src/lib.rs.
- Added a test-case to src/intr.rs (test_breakpnt_exc).
0.4.1
- Added support for the time crate, but said crate has not been put to any use, as of now.
- Removed some notes that were cluttering up the Cargo.toml file.
0.4.0 - BASIC HANDLING OF CPU EXCEPTIONS
- Implemented a basic method for handling CPU exceptions (see src/intr.rs).
- Enabled the "abi_x86_interrupt" feature.
0.3.3
- Fixed the issue that would cause the kernel to panic when running the basicboot test.
- Added the shouldfail test-case to the shouldpanic component of the tests library.
- Removed the test-harness for the shouldpanic test.
0.3.2
- Renamed the name of the crate to "libertyos_kernel".
- Created a new library to handle tests.
- Added the basicboot test.
- Removed a TODO note from main.rs, about fixing the issues that prevented the kernel from compiling for testing.
- Created a lib.rs file, with some basic code to handle the kernel's ever-expanding code.
- Removed some code from main.rs, as lib.rs now handles part of what main.rs used to handle.
- Integrated the tests crate into the kernel's code, so that the whole thing compiles. The tests panic, but that should be fixed soon.
0.3.1
- Added a rust-toolchain file, so that the nightly version of Rust is used by default.
- Commented out a test-case that was preventing the kernel from compiling.
0.3.0 - BASIC TESTING
- Removed the [profile.dev] section from Cargo.toml.
- Removed the [profile.release] section from Cargo.toml.
- Added the CanTest trait to src/main.rs.
- Added an implementation of the CanTest trait, to src/main.rs.
- Added the test_simple_println test-case.
- Renamed the trivassert test case to test_trivassert, so that the test-cases are easily identifiable.
- Removed the previous method of executing tests, found in the "for test in tests" section of the testexec function.
- Implemented CanTest's run to the testexec function.
- Removed the text that was printed when executing the test_trivassert test-case.
- Fixed the issues that prevented "cargo test" from compiling successfully. The included tests should work as intended.
0.2.9
- Added an key to the [package.metadata.bootimage], so that QEMU exits after five minutes of running the trivassert test case.
0.2.8
- Configured Cargo.toml, so that when running tests (using QEMU), information is output to serial, rather than to the VGA buffer, in a seperate window.
- Modified the formatting used in the "test-args" attribute of the [package.metadata.bootimage] section. The changes in question serve no functional purpose, but make the file look nicer. :)
- Created a separate panic-handler for booting the kernel in testing/debug mode.
- Created an attribute, for what was the sole panic-handler, so that the kernel uses the original panic-handler, rather than the panic-handler that should be used when running tests in QEMU.
0.2.7
- Configured bootimage's arguments, in Cargo.toml, so that QEMU prints messages to stdout, in addition to being output to the VGA buffer.
0.2.6
- Modified the trivassert test case, so that it uses the serprint and serprintln macros
- Added some details to the Cargo.toml, so that the kernel can be published to crates.io (It has not been published, but should be in the near future)
0.2.5
- Removed a TODO note, about removing unsafe function in main.rs
- Added a TODO task, to fix the issues that prevent kernel tests from compiling
0.2.4
- Added serprint macro
- Added serprintln macro
- Added an expect message for the _print function of the ser module
