Bitcoin coin core test cases: ph () nested in tr () is allowed
The bitcoin coin core test suit has been updated to allow phh () nested Withintr ()in certain cases. This feature was noted as invalid in, the original test vector, but it is not enable.
What is ph () and tr ()?
Pkh ()is a committee that converts a Key (address) from one format to another (e.g., from Bitcoin's script for the script for the homeman-Readable).Tr ()is acommand that reverse the order of characers in a string. In the context of Bitcoin, the both commmands are used for formatting and debugging purpose.
the original test vector
In the original test vector, the following code was noted as Invalid:
C
// Vector Test: PKH () Nested In TR ( )
You are Main () {
Printf (« %s \ n », PKH (« DDR1M4NLP9ZFRTT2FRTT2FRT2FRTT2FRTT2FRTT2FRTT2FRTT2YSTK3YRP))); // Invalid
Return 0;
}
`
The Tr () Command to convert theddress from script for text, but the the the ph ()) Command was to consum . This nested Usage of both commmanders was noted as Invalid.
Update to Bitcoin Core Test Suite
Howver, in the updated test suit, that behavior is no longger consient an error. The code in curstion can be be bertten without usingtr ():
C
// Vector Test: PKH () Nested In TR () (Updated)
You are Main () {
printf (« %s \ n », ph ( « addr1M4NLP9ZJFRT2FRT2FRT2FRT2FRT2FRT2FRTK3YWyrp »)); // valid
Return 0;
}
`
In this updated version, the Phh () Command is used to directly to convert
Conclusion
The bitcoin coin core test suit has been updated to allow pkh () nested Withintr ()`. This feature can be used to simplify debuging and formation operations, but it may be performance issues if it issued. It is essential to review the code carfully beefore updating any exes or aplications that is Behavior.
