Lucas CHOLLET	3b824ec8c9	AK+Test: Fix a logic error in CircularBuffer::offset_of() ... This error was introduced by 9a7accdd and had a significant impact on `BufferedFile` behavior. Hence, we started seeing crash in test262. By itself, the issue was a wrong calculation of the internal reading spans when using the `read` and `until` parameters. Which can lead to at worse crash in VERIFY and at least weird behaviors as missed needles or detections out of bounds. It was also accompanied by an erroneous test. This patch fixes the bug, the test and also provides more tests.	2023-01-15 23:23:24 +00:00
Lucas CHOLLET	9a7accddb7	AK: Add an optional starting offset to CircularBuffer::offset_of ... This parameter allows to start searching after an offset. For example, to resume a search. It is unfortunately a breaking change in API so this patch also modifies one user and one test.	2023-01-14 16:20:30 -07:00

Lucas CHOLLET	f12e81b74a	AK: Add CircularBuffer ... The class is very similar to `CircularDuplexStream` in its behavior. Main differences are that `CircularBuffer`: - does not inherit from `AK::Stream` - uses `ErrorOr` for its API - is heap allocated (and OOM-Safe) This patch also add some tests.	2022-12-31 04:44:17 -07:00
