The trash buffers are becoming increasingly complex to deal with due to the code's modularity allowing some functions to be chained and causing the same chunk buffers to be used multiple times along the chain, possibly corrupting each other. In fact the trash were designed from scratch for explicitly not surviving a function call but string manipulation makes this impossible most of the time while not fullfilling the need for reliable temporary chunks. Here we introduce the ability to allocate a temporary trash chunk which is reserved, so that it will not conflict with the trash chunks other functions use, and will even support reentrant calls (eg: build_logline). For this, we create a new pool which is exactly the size of a usual chunk buffer plus the size of the chunk struct so that these chunks when allocated are exactly the same size as the ones returned by get_trash_buffer(). These chunks may fail so the caller must check them, and the caller is also responsible for freeing them. The code focuses on minimal changes and ease of reliable backporting because it will be needed in stable versions in order to support next patch. |
