Release Build

This distribution is a RELEASE build and has little trace and or debug assertions to help find bugs. If you rebuild from source code, a DEBUG build may be created which has more trace to assist in debugging. Performance with the DEBUG build will be slower and the memory footprint will be larger than with the release build.

Helpful Hints

Debug Trace and Logging

Appweb has a logging and trace facility that can help greatly when diagnosing configuration issues or developing your application code that uses Appweb. You can see what modules are loaded and how, what requests arrive and how they are serviced. You can also vary the level of logging via the appweb.conf configuration file or via the -l logfile command line switch. The log command line switch has the format

-l logFile:logLevel

where level can be from 0 to 9, with 9 being the most verbose level. A level of 6 usually gives plenty of detail. You can define the log file and log level via the appweb.conf file using the ErrorLog and LogLevel directives.

Resolved Issues

See the new features and fixes in the New Features document.
