Fix encoding to properly use provided encoding table parameter instead of
hardcoded `ENC_TABLE`.
This makes encode properly support custom alphabets as documented.
Add support for custom alphabet validation through an optional validation
function parameter. The default validation follows RFC 4648 base32
alphabet rules (A-Z, 2-7).
This properly supports the documented ability to use custom alphabets.
Replace package-level map with a simple switch statement for padding
validation. This eliminates allocations we can't properly free while
maintaining the same validation logic.
This provides an equivalent to `assert` and `assert_contextless` that
are always evaluated, ignoring `ODIN_DISABLE_ASSERT`, which is useful
for enforcing API contracts or "asserting" on conditionals with
side-effects.
Fix memory handling throughout base32 package:
- Make padding map package-level constant (to avoid repeated allocs)
- Use passed allocator in encode's make() call
- Add defer delete for allocated memory in encode
- Add proper cleanup in test cases
- Fix memory cleanup of output buffers
The changes ensure consistent allocator usage and cleanup in both
implementation and tests.
Add test suite based on RFC 4648 test vectors and validation rules:
- Add section 10 test vectors for valid encoding/decoding
- Add test cases for invalid character handling (section 3.2)
- Add test cases for padding validation (section 4)
- Add test cases for length requirements (section 6)
The test vectors verify that:
- Empty string encodes/decodes correctly
- Standard cases like "foo" -> "MZXW6===" work
- Invalid characters are rejected
- Missing or malformed padding is detected
- Invalid lengths are caught
Fix buffer allocation size calculation and add proper bounds checking to
ensure output buffer has sufficient space. This fixes crashes that could
occur with inputs like "AA" and other edge cases where the output buffer
was too small.
Remove #no_bounds_check as proper bounds checking is necessary for safe
error handling. The small performance trade-off is worth the improved
robustness.
Replace assertions with proper error handling in base32.decode() to allow
programs to handle invalid input gracefully rather than crashing.
The function now returns ([]byte, Error) instead of just []byte.
When trying to set arena.curr_block.used = 0 after mem.zero() caused a crash because if the arena is bootstrapped its memory will be zeroed out after mem.zero() thus making arena.cur_block point to zero.
Disallow the declaration of new parapoly variables in return types, when
the procedure's parapoly scope is itself. This happens if e.g.:
`foo :: proc() -> $T`.
Closes#3949, #4294, #4563
Readded open flags for arm64 to sys/linux/bits.odin. Make process_start
name based instead of descriptor based to allow running of scripts. Fix
bug in heap_linux. Fix and simplify os2.remove.
If a procedure was marked `#force_no_inline`, any procedure calls within
it would also implicitly be. This is not expected for multiple reasons:
1. `#force(_no)_inline` on a call expr works differently than on a procedure literal.
2. Adding the attribute on it and every called proc blows up the amount
of work for the inliner pass and may increase the time it takes.
3. Putting `#force_no_inline` on a procedure to keep executable size
down (like we do for some map procedures), benchmark it, or find it in
asm/ir has the added effect of slowing those procedures down significantly
and not representing truth.
