store: don't read the whole fncache in memory In large repositories with lot of files, the fncache grows more than 100 MB and reading that whole thing into memory slows things down. Let's not read the whole thing into memory. This patch changes fncache loading code to read 1 MB at once. Loading 1 MB at once saves ~1 sec on perffncacheload for our internal repository. I tried various values such as 0.5 MB, 5 MB, 10 MB but best results were produced using 1 MB as the chunksize. On a narrow clone with fncache around 40 MB, this patch saves ~0.04 seconds on average on perffncacheload. To test the code, I have coded an extension in test-fncache.t which set chunksize to 1 byte, and the test passes with that. Differential Revision: https://phab.mercurial-scm.org/D5296

:alt: Code Coverage
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).
