This is to avoid failing strict compile time warnings downstream when the feature is disabled.</p> <p>There are no functional differences to v1.2.2</p> spaskalev tag:github.com,2008:Repository/334767584/v1.2.2 2025-02-18T19:21:09Z <ul> <li>Fixed a bug in arena downsizing that could lead to duplicate allocations.</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v1.2.1 2024-12-21T17:53:49Z <ul> <li>Fixed a bug affecting the <code>buddy_can_shrink</code> function, added more tests for up-resizing an arena in normal and embedded mode.</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v1.2.0 2024-09-23T07:03:17Z <ul> <li>Add a new <code>buddy_get_embed_at</code> function to get a handle to the allocator when having a pointer to the arena.</li> <li>Add a new <code>enum buddy_safe_free_status</code> that is returned from the <code>buddy_safe_free</code> function. It can be used to detect invalid free calls and fail early.</li> <li>Document the allocator metadata size based on some common arena and smallest allocation block sizes.</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v1.1.1 2024-06-15T00:01:11Z <ul> <li>Support compiling with Pelles C</li> <li>Add a cmake target for the benchmark</li> <li>Fixed a few harmless compile warnings</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v1.1.0 2023-11-22T22:13:22Z <ul> <li>Add a parameter to <code>buddy_realloc</code> that allows it to ignore data. Useful for resizing buffers when there is no longer any interest in their content.</li> <li>Minor style and repo changes.</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v1.0.0 2023-10-09T13:01:30Z <p>External changes:</p> <ul> <li><code>buddy_walk</code> callback is now invoked for free slots in addition to allocated ones and has an extra parameter to distinguish between free and allocated.</li> <li><code>buddy_fragmentation</code> return type is now an <code>unsigned char</code> that ranges between 0 and 255 and no <code>float</code> types are used. This way fragmentation can be reported when used in environments that don't support the <code>float</code> type.</li> </ul> <p>Internal changes:</p> <ul> <li>A static inline <code>two_to_the_power_of</code> helper function that returns <code>size_t</code> is used in place of manual power of two calculations.</li> <li>The fast square root algorithm used in the fragmentation formula has been replaced with an integer square root algorithm by Martin Guy, 1985.</li> </ul> <p>Misc:</p> <p>Two years and nine months have passed since this project started and it has now reached the <code>1.0.0</code> milestone. Thanks to all contributors and users for their interest in it.</p> spaskalev tag:github.com,2008:Repository/334767584/v0.9 2023-08-22T19:41:10Z <ul> <li>Remove FAMs and <code>{0}</code> initializers to facilitate interop with strict C++ compilers <ul> <li>Clang generates identical code with FAMs and without FAMs</li> <li>GCC generates almost-identical code</li> </ul> </li> <li>Make the debug functions non-static so that they can be used by code in other units</li> <li>Include <code>stdio.h</code> only when <code>BUDDY_PRINTF</code> is not defined</li> <li>Add a macro for C++ name mangling</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v0.8 2023-06-13T05:52:47Z <ul> <li>The allocator is now easier to use within a linux kernel/module. <ul> <li>Conforms to the c90-style variable declarations in functions</li> <li>New defines <code>BUDDY_PRINTF</code>, <code>BUDDY_HEADER</code> and <code>BUDDY_FRAG_OPTIONAL</code> added to allow conditional inclusion of functionality and setting a suitable printf-like function for the debug functions.</li> </ul> </li> <li>Fixed some issues with explicit alignment init functions</li> <li>Fixed UB on invalid free calls</li> </ul> spaskalev tag:github.com,2008:Repository/334767584/v0.7.2 2023-06-10T18:34:00Z <ul> <li>Additional performance improvements</li> <li>Stricter compile-time checks</li> <li>Fixed code coverage reporting and got coverage back to 100%.</li> </ul> spaskalev
