2018-09-11Small optimizations for CBC_HighLevelEncoder::lookAheadTestchromium/3550Ryan Harrison
Currently ClusterFuzz is timing out when running cases that cause a large number of calls to this method. Looking at the cases, I believe these to be valid calls, so this CL attempts to lower the cost of making each individual call. Adds in pre-allocation of a vector that has a fixed size and uses a const-ref for passing in |msg| to avoid copying.

2017-09-18Convert string class namesRyan Harrison
Automated using git grep & sed. Replace StringC classes with StringView classes. Remove the CFX_ prefix and put string classes in fxcrt namespace. Change AsStringC() to AsStringView(). Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*, Foo). Couple of tests needed to have their names regularlized.

2017-09-06Convert FX_STRSIZE int->size_tRyan Harrison
Change the underlying type for FX_STRSIZE to size_t from int. This will make the value unsigned and thus all values in the range of the type will be valid. This allows for the final remove of negative length strings, but also introduces a some casting and functional errors, since many parts of the code base assume that FX_STRSIZE is int or another signed type. This also CL fixes these errors.

2017-09-01Cleanup usages of Mid(foo, 1), Right(1), and Left(1)chromium/3203Ryan Harrison
Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly Left(1) is [0]. It is faster also, since it does not need to create intermediate strings. Right(1) is a touch more tricky, since it requires something like GetLength() ? [GetLength() - 1] : 0;. A new method, Last() has been added to perform this character extraction. Multiple call sites have been updated to use more efficient/simpler syntax. There are a number of call sites that use on these patterns, but based on the surrounding context we actually need/want a string, so they have not been modified.

2017-08-15Remove GetAt from string classesRyan Harrison
This method duplicates the behaviour of the const [] operator and doesn't offer any additional safety. Folding them into one implementation. SetAt is retained, since implementing the non-const [] operator to replace SetAt has potential performance concerns. Specifically many non-obvious cases of reading an element using [] will cause a realloc & copy.

2017-07-28Convert calls to Mid() to Left() or Right() if possibleRyan Harrison
The various string/byte classes support Mid(), Left(), and Right() for extracting substrings. Mid() can handle all possible cases, but Left() and Right() are useful for common cases and more explicit about what is going on. Calls like Mid(offset, length - offset) can be converted to Right(length - offset). Calls like Mid(0, length) can be converted to Left(length). If the substring being extracted does not extend all the way to one of the edges of the string, then Mid() still needs to be used.
