As far as I can see, the newtest_can_use_large_primary_keystest can never have passed on postgres. There is no concept of unsigned in postgres, meaning a primary key bigger than 2147483648 only fits in a bigint/bigserial. The latter is used for theAutoFielditself in this patch, but ...
When working with bytes in Java, it’s crucial to understand that thebytetype is signed, meaning it can represent both positive and negative values. However, in many scenarios, especially when dealing with binary data or network communication, we need to treat bytes as unsigned values to ensure...
The incoming data is received as "const char*" (BASE64 characters are always safe ASCII characters, meaning they will always fit in a signed char positive range). The resulting decoded data is placed in memory, and the function exposes an "unsigned char*" to the caller. What does ANSI C...
Note: Both unsigned and signed are just ways of representing a byte. A byte has meaning in either representation. Conversion to unsigned byte To convert a number into an unsigned byte, you have to use a larger data type to store the number. So take for example a value 183, must be rep...
Compilers can, of course, define the meaning of certain constructs beyond the requirements of the standard, as a compiler extension. Accessing inactive member of a union - especially when all members are PODs - is indeed unlikely to produce surprises, given that most C++ compilers are also (or...
