Message252322
Attached patch is the first step to optimize Unicode encoders: it adds a _PyBytesWriter API. This API is responsible to use the most efficient buffer depending on the need:
* it's possible to use a small buffer directly allocated on the C stack
* otherwise a Python bytes object is allocated
* it's possible to overallocate the bytes objcet to reduce the number of calls to _PyBytes_Resize()
The patch only adds the new API, don't expect any speed up. I just added a small optimization: the overallocation is disabled in UCS1 encoder (ASCII and Latin1) for the last write. |
