* | | Relax _PyBytesWriter APIVictor Stinner2015-10-121-8/+7
| | | | | | | | | | | | | | | | | | | | | Don't require _PyBytesWriter pointer to be a "char *". Same change for _PyBytesWriter_WriteBytes() parameter. For example, binascii uses "unsigned char*".

* | | Issue #25349: Optimize bytes % intVictor Stinner2015-10-091-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X. _PyBytesWriter is now used to format directly the integer into the writer buffer, instead of using a temporary bytes object. Formatting is between 30% and 50% faster on a microbenchmark.

* | | _PyBytesWriter: simplify code to avoid "prealloc" parametersVictor Stinner2015-10-091-9/+7
| | | | | | | | | | | | | | | Substract preallocate bytes from min_size before calling _PyBytesWriter_Prepare().

* | | Issue #25349: Optimize bytes % args using the new private _PyBytesWriter APIVictor Stinner2015-10-091-59/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Thanks to the _PyBytesWriter API, output smaller than 512 bytes are allocated on the stack and so avoid calling _PyBytes_Resize(). Because of that, change the default buffer size to fmtcnt instead of fmtcnt+100. * Rely on _PyBytesWriter algorithm to overallocate the buffer instead of using a custom code. For example, _PyBytesWriter uses a different overallocation factor (25% or 50%) depending on the platform to get best performances. * Disable overallocation for the last write. * Replace C loops to fill characters with memset() * Add also many comments to _PyBytes_Format() * Remove unused FORMATBUFLEN constant * Avoid the creation of a temporary bytes object when formatting a floating point number (when no custom formatting option is used) * Fix also reference leaks on error handling * Use Py_MEMCPY() to copy bytes between two formatters (%)

* | #16518: Bring error messages in harmony with docs ("bytes-like object")R David Murray2014-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | Some time ago we changed the docs to consistently use the term 'bytes-like object' in all the contexts where bytes, bytearray, memoryview, etc are used. This patch (by Ezio Melotti) completes that work by changing the error messages that previously reported that certain types did "not support the buffer interface" to instead say that a bytes-like object is required. (The glossary entry for bytes-like object references the discussion of the buffer protocol in the docs.)
