Description

With Stack Trace Logging set to Full, Unity puts native frames such as 0x00007ffd387f224e (Unity) StackWalker::ShowCallstack between the message and the managed trace. FindStackStartIndex had no pattern for those lines, so the split happened at the first managed frame and every native frame stayed in the message body, even with include_stacktrace: false. This adds a check for lines that start with 0x<hex> (.

I didn't touch the second thing mentioned in #1433 (a types: ["error"] read returning a Debug.Log entry). I couldn't reproduce it from the issue text alone and didn't want to guess.

Type of Change

• Bug fix (non-breaking change that fixes an issue)

Changes Made

• ReadConsole.cs: IsNativeStackFrame helper used by FindStackStartIndex; SplitMessageAndStackTrace is now internal so it can be tested directly, like GetLogTypeFromMode.
• ReadConsoleTests.cs: one test with the frame layout from the issue, and one checking that a body line like 0x1F is the header byte is not taken as a frame.

Compatibility / Package Source

• Unity version(s) tested: 6000.3.9f1
• Package source used: file: (the TestProjects/UnityMCPTests setup)

Testing/Screenshots/Recordings

• Unity EditMode tests

ReadConsoleTests: 22/22. With the IsNativeStackFrame check removed, SplitMessageAndStackTrace_StripsNativeFrames fails (the body runs on into the native frames). Full EditMode run: 1472 passed, 79 ignored, 0 failed.

Fixes #1433

Summary by CodeRabbit

• Bug Fixes
  • Console messages now separate native Unity stack traces from log text, making stack traces easier to identify while preserving message text that begins with hexadecimal characters.

📝 Walkthrough

Walkthrough

ReadConsole now recognizes Unity native stack frames when separating a message body from its stack trace. The method is internal. Two EditMode tests cover native frames and hexadecimal-looking message text.

Changes

Console stack parsing

Layer / File(s)	Summary
Native frame detection and validation MCPForUnity/Editor/Tools/ReadConsole.cs, TestProjects/UnityMCPTests/Assets/Tests/EditMode/Tools/ReadConsoleTests.cs	SplitMessageAndStackTrace is now internal. FindStackStartIndex recognizes native frames with an 0x prefix, 8 or 16 hexadecimal digits, a nonempty module label, and a nonempty symbol. Tests check that native frames are split from the message and that hexadecimal-looking body lines remain intact.

Merge Risk: 🔵 Low · up to 679ae

Some multiline console messages can be truncated with the default stack-trace setting. The impact is limited, but the frame check should be tightened before merge if preserving those messages is required.

Explanation

For #1433, the new native-frame check recognizes the reported 0x… (Module) symbol lines, and the tests verify that those frames are split from the message while a hex-like body line remains intact. The inspected code also passes types to GetConsoleEntries, but the available source excerpt does not show the type-filtering branch. The possible types: ["error"] anomaly is therefore unresolved; the evidence does not establish whether an error-only read excludes Log entries.

- Line 719: Update FindStackStartIndex to recognize a stack start only when the
remainder matches a complete Unity frame shape, including a module label and
frame symbol, rather than merely the `0x... (` prefix. Preserve body text such
as `0x1F (header byte)` followed by more text, and add that case to the
preservation test for SplitMessageAndStackTrace with `format: "plain"`.
