Central Bitcoin Test Cases: PKH () Nesty in TR () It is allowed
The Bitcoin Core test process has been updated to allow pkh () nestled within TR () in certain cases. This feature has been observed invalid in the original test vector, but is not activated.
What is pkh () and TR ()?
pkh ()It is an accommoda that converts a key (address) from one format to another (for example, the Bitcoin source script to formation).TR ()It is an acomatory that reverses the order of the characters in a string. In the context of Bitcoin, the two are used for formatting and clearance purposes.
The original test vector
In the original test vector, the following code is observed as invalid:
c
// test vector: pkh () nestled in TR ()
int main () {
Printf (“%s n”, pH (TR (“Addr1M4NLP9ZJFRT2FRT2FRT2F7VWQG5DXSTK3YWYRP”)))))))); // Invalid
Return 0;
}
`
The TR () command to convert the script DRESFT to text, but the command pkh () to consume ormat. This nestled use of both commanders was known as invalid.
Update for Bitcoin Core Test Suite
On the other hand, in the updated test process, this behavior is not a longtime conscious mistake. The curse code can be BRETENGTED WHOUTOUT usingTR ():
c
// Test vector: pkh () nestled in TR () (updated)
int main () {
Printf (“%s n”, pH (“ADDR1M4NLP9LP9ZJFRT2F7VWQG5DXSTK3YWYRP”) // VALID
Return 0;
}
`
In this updated version, the pkh () command is used directly to convert
Conclusion*
The Bitcoin Core costume has been updated to allowpkh ()nestled inTR ()`. This feature can be used to simplify clearance and training operations, but it can be performance problems if issued. It is essential to review the Core Cardi Bee before updating all ex -applications, this is behavior.
