Enhance Log Entry and add unique code for ERROR & WARNING level #1256

Trouffman · 2025-04-25T14:14:56Z

Additional reformatting of the Log entries for consistency & further add unique identifier for each unique ERROR/WARNING level.

Goal

Easier to search solution for a specific error
Less confusion between error log entries
Could help to automate basic support / log analysis
Numerical value is irrelevant to other similar 3digit error code (like HTTP)

What has been done

Further enhance previous Log Entry reformatting
All ERROR level message now have a unique identifier : "ERR-XXX"
All WARNING level messages now have a unique identifier : WARN-XXX

Format & consistency rules

WARN-XXX for LOG_WARNING level entries
ERR-XXX for any LOG_ERROR level entries
XXX is 3 digit
XXX does not relate to any other error code that exists (like HTTP Code)
Some XXX ID can be used of left for special (fun) purpose

like 404 when the NDI library is not found) but is discretionary

XXX value is unique across any LOG_LEVEL
If a downgrade from ERROR to WARNING : the 3 digits stay the same
If an upgrade from WARNING to ERROR : the 3 digits stay the same
If a downgrade to a non-WARNING/ERROR level, keep the log Entry ID. (INF-)

In some cases this can be move to the end of the log-entry
If not-upgraded within 12months AND more than 1 Major releases AND in need for cleanup : Code can be "retired" but must still be accessible for historical purposes (wiki?).

If the Message attached change : the ERROR code stay the same
Log Entry are Specific to the error / location in code / Trigger reason / Root cause. Therefore, If the code change, evaluate if this is the same error / log entry or a new one.
In case we go through more than 999 Error/warning ID... The project will be VERY successful, just add a digit.

To-Do

Add ERROR Code to the WIki for the relevant Issues / troubleshooting steps
Only use the code/ID, not the LOG-ENTRY message (easier to maintain)

Pull Request Overview

This PR enhances logging consistency by embedding unique error and warning codes across various modules to aid in the search for and analysis of log entries. Key changes include:

Prefixing log messages with specific error/warning codes (e.g. ERR-XXX and WARN-XXX) for ERROR and WARNING levels.
Standardizing log message text to use consistent capitalization for “NDI Main Output”.
Updating log levels and messages across multiple files (preview output, update, ndi-source, ndi-output, etc.) for better clarity.

src/preview-output.cpp:241

[nitpick] There is a potential duplication in logging: immediately after logging the warning message, a debug message with similar content is issued. Consider consolidating these logs or clearly distinguishing their purposes to reduce redundancy.

obs_log(LOG_WARNING, "WARN-423 - Failed to create NDI Preview Output '%s'", QT_TO_UTF8(output_name));

src/ndi-source.cpp:926

[nitpick] A debug log is emitted immediately before a warning log (with WARN-414) for invalid config behavior. Consider either consolidating these logs or using a consistent log level to avoid potential confusion.

obs_log(LOG_DEBUG, "'... ndi_source_update: Invalid or unknown behavior detected :'%s' forced to '%d'", obs_source_name, behavior, PROP_BEHAVIOR_KEEP_ACTIVE);

src/forms/update.cpp:307

The log macro used is 'DEBUG', which is inconsistent with the other parts of the code that use 'LOG_DEBUG'. Using a consistent log level macro improves clarity.

obs_log(DEBUG, "onCheckForUpdateNetworkFinish: Error! httpStatusCode=%d, errorData='%s'; ignoring response", httpStatusCode, QT_TO_UTF8(pluginUpdateInfo.errorData));

I need to check where this is coming from.
