Walkthrough

The change simplifies the string assignment in the get_string_value method of the ACE_Configuration_Win32Registry class by replacing the previous call to value.set(buffer.get(), buffer_length, true); with a direct assignment value = buffer.get();. The overall control flow and error handling remain unchanged, and there is no modification to public or exported entity declarations.

Poem

I'm a rabbit in the code burrow, hopping with glee,
A string now set directly, as simple as can be.
No more complex calls to manage my flow,
Just a swift assignment that makes the code glow.
I nibble on bugs, watch them scurry away,
Celebrating clear paths on this bright coding day!

❓ Verification inconclusive

Consider potential implications of using direct assignment

This PR reverts the change made in PR #1710 where the explicit string setting method was replaced with a direct assignment. The assignment value = buffer.get() assumes that the string in buffer is properly null-terminated. If the Windows Registry API returns non-null-terminated strings in some cases, this could potentially lead to issues.

The original PR (#1710) titled "Fix assigning not null-terminated string" was likely addressing a specific issue. Please verify that this reversion doesn't reintroduce the original problem by checking:

Direct Assignment Review – Verify ACE_TString’s Handling of Null Termination

The change reverts an earlier fix by replacing the explicit string-setting method with a direct assignment (value = buffer.get()). Given that this assumes the buffer contains a properly null‐terminated string, there’s a risk if the Windows Registry API returns non-null-terminated strings.

Our initial search for the implementation of ACE_TString (using rg -A 10 "class ACE_TString" --type cpp) returned no output. This leaves us without conclusive evidence on whether the assignment operator in ACE_TString has its own safety checks or performs additional null-termination validation.

Action Required:

• Manual Verification: Please verify the implementation of ACE_TString (or related string handling code) to ensure that it safely handles non-null-terminated input on assignment.
