v2.11

A small minor release, driven by features proposed by @sosthene-nitrokey and @yamt, with bug fixes from @DvdGiessen, @selimkeles, and yours truly. ### What's new? - Thanks to @sosthene-nitrokey, `lfs_fs_grow` now supports a **limited** form of filesystem shrinking ([#1094](https://github.com/littlefs-project/littlefs/pull/1094)) If compiled with `LFS_SHRINKNONRELOCATING`, `lfs_fs_grow` can be used to reduce the `block_count`, as long is it does not require block relocation. This provides a useful path for migrating from old filesystem images created when littlefs ignored the on-disk `block_count`. Note that this is unreliable for general use. littlefs allocates blocks pseudorandomly as a part of wear-leveling, so `LFS_SHRINKNONRELOCATING` is unlikely to succeed even with small filesystems. - Thanks to @yamt, `make test` should now work on Mac out of the box. This required linker and Makefile changes due to littlefs's test-runner quirks ([#1090](https://github.com/littlefs-project/littlefs/pull/1090), [#1091](https://github.com/littlefs-project/littlefs/pull/1091)) As a side-effect, littlefs's Makefile can now compile with Clang. The only limitation being that stack measurements are currently broken. If anyone knows a good Clang alternative to GCC's `-fcallgraph-info=su`, feel free to create an issue (or PR if you're willing to write a bit of python). littlefs's Makefile can also compile with other non-Clang non-GCC compilers if you set the `NO_GCC` environment variable. - @DvdGiessen fixed several bugs related to LFS_CRC ([1095](https://github.com/littlefs-project/littlefs/pull/1095)) - User provided LFS_CRCs no longer create multiple definitions if `lfs_util.h` is included in more than one file. - LFS_CRC no longer needs a trailing semicolon. - Thanks to @selimkeles, `lfs_fromle32`/`lfs_frombe32` no longer risk overflow on 16-bit devices ([#1100](https://github.com/littlefs-project/littlefs/pull/1100)) - Found by @Hugh-Baoa, fixed a double deorphan that can occur if an mdir relocates during a remove operation ([#1099](https://github.com/littlefs-project/littlefs/pull/1099)) - Thanks to @DvdGiessen, `changeprefix.py` no longer breaks if /tmp lives on a different filesystem ([#1104](https://github.com/littlefs-project/littlefs/pull/1104)) ### Changes | | Code | Stack | Structs | | Coverage | |:--|-----:|------:|--------:|:--|---------:| | Default | 17104 B (-0.1%) | 1448 B (+0.0%) | 812 B (+0.0%) | Lines | 2434/2595 lines (+0.0%) | | Readonly | 6230 B (+0.0%) | 448 B (+0.0%) | 812 B (+0.0%) | Branches | 1283/1616 branches (-0.0%) | | Threadsafe | 17956 B (-0.1%) | 1448 B (+0.0%) | 820 B (+0.0%) | | **Benchmarks** | | Multiversion | 17176 B (-0.1%) | 1448 B (+0.0%) | 816 B (+0.0%) | Readed | 29369693876 B (+0.0%) | | Migrate | 18768 B (-0.1%) | 1752 B (+0.0%) | 816 B (+0.0%) | Proged | 1482874766 B (+0.0%) | | Error-asserts | 17916 B (+0.1%) | 1440 B (+0.0%) | 812 B (+0.0%) | Erased | 1568888832 B (+0.0%) | [`8434536`](https://github.com/littlefs-project/littlefs/commit/8434536) Bumped minor version to v2.11 [`ba250a3`](https://github.com/littlefs-project/littlefs/commit/ba250a3) use shutil.move instead of os.rename to move file [`0115cf6`](https://github.com/littlefs-project/littlefs/commit/0115cf6) gha: Dropped explicit CFLAGS from clang testing in CI [`bff4dfd`](https://github.com/littlefs-project/littlefs/commit/bff4dfd) Added NO_GCC to allow users to explicitly disable GCC-specific flags [`edaaaf8`](https://github.com/littlefs-project/littlefs/commit/edaaaf8) Apply review comments [`7d79423`](https://github.com/littlefs-project/littlefs/commit/7d79423) Rename SHRINKIFCHEAP to SHRINKNONRELOCATING [`7782d3d`](https://github.com/littlefs-project/littlefs/commit/7782d3d) Mention that shrinking is unlikely to work [`f4a1bb3`](https://github.com/littlefs-project/littlefs/commit/f4a1bb3) fix: added uint32_t cast to the bitshift places In 16 bit and 8 bit architectures, overflow and underflow issues were occuring while using functions lfs_frombe32 and lfs_fromle32 [`9b8f802`](https://github.com/littlefs-project/littlefs/commit/9b8f802) fixup!
