2021-06-30Don't allow implicit conversion to Arrayandroid-s-beta-5android-s-beta-4android-s-beta-3android-s-beta-5android-s-beta-4Seth Moore
The variadic Array constructor would implicitly make an Array object from a single input that is convertable to an Item. This leads to surprising behaviors wherein Arrays could be created unintentionally. Fix this by making the variadic constructor only work for more than one argument. Add an additional, single-item constructor that is explicit. Bug: 191778240 Test: cppbor_host_test_external Change-Id: Ifadc6d3137ee285a81076a4125b6053f1d7c21c4

This fixes an incorrect integer cast in the handleNint function in cppbor_parse.cpp which would trigger UBSAN failures in the Trusty apploader. Change-Id: Id35865e524c9837d907fe352feac783b3f7f36b0

2021-03-11Add view items for zero-copy parsing of CBOR stringsAndrei Homescu
This CL adds two new ViewTstr and ViewBstr Item types that hold strings as string_view and basic_string_view<uint8_t> types instead of std::string or std::vector<uint8_t>, respectively. This allows for zero-copy parsing of CBOR (mainly strings), which is useful in low-memory environments like the apploader where CBOR data can contain large bstr values.

2020-12-14Change semantic tagging.Shawn Willden
Semantic tagging in libcppbor was a bit cumbersome to use, with tags treated as separate items, requiring code that analyzes tagged data to pay attention to the tags. Among other issues, that violates the intention of semantic tagging in CBOR, which, per the RFC, does not require decoders to understand tags. This CL changes that behavior so that code that walks a parsed Item tree will not "see" the tags unless it looks for them, by calling "Item::semanticTagCount()" and then "Item::semanticTag()". Nested tags are supported. Test: cppbor_test_external Change-Id: Ifa99475fd0d9f369f3e379251979446a2ec262b5
2020-12-14Remove downcastItem<>Shawn Willden
This safe downcast template was never used and is hard to implement with the coming SemanticTag changes, so this CL removes it. Test: cppbor_test_external Change-Id: I0d4dd8b7323653c3924080f8fb328282dbca4566
2020-12-14Improve Map canonicalization and add Map iterators.Shawn Willden
This CL changes Map storage to use a vector of pairs, which removes the need to copy the contents twice to sort them and makes it easy to support Map iteration. Support for recursive canonicalization is added as well, and Map::get() uses a binary search when the map is canonicalized.
