merge: add mergeresult.mapaction to improve speed As a part of [hg update] we convert all [ACTION_CREATED] merge results into [ACTION_GET] actions, and that's slightly inefficient because every insertion pays the full cost of maintaining the [mergeresult] data structure up to date. This commit adds a function [mapaction], which is faster. (saves around 0.3s on a large update involving ~400k files)

mercurial/thirdparty/cbor/README.rst

This library provides encoding and decoding for the Concise Binary Object Representation (CBOR) (RFC 7049) serialization format.

There exists another Python CBOR implementation (cbor) which is faster on CPython due to its C extensions. On PyPy, cbor2 and cbor are almost identical in performance. The other implementation also lacks documentation and a comprehensive test suite, does not support most standard extension tags and is known to crash (segfault) when passed a cyclic structure (say, a list containing itself).
