Enhanced Log viewer

By A.Bouchez on 2011, Saturday August 20, 10:24 - Open Source libraries

We already shipped a sophisticated set of logging classes some month ago.

Since then, its features have been enhanced, and the system has been deeply interfaced with our main ORM framework. Now almost all low-level or high-level operations can be logged on request.

But since the log files tend to be huge (for instance, if you set the logging for our unitary tests, the 6,000,000 unitary tests creates a 280 MB log file), a log viewer was definitively in need.

Enhanced logging in SynCommons

By A.Bouchez on 2011, Thursday April 14, 05:34 - Open Source libraries

Logging is everything... unless you never wrote a bug in your program! :)

Let us introduce a new logging class:

  • logging with a set of levels;
  • fast, low execution overhead;
  • can load .map file symbols to be used in logging;
  • compression of .map into binary .mab (900 KB -> 70 KB);
  • inclusion of the .map/.mab into the .exe;
  • reading of an external .map to add unit names and line numbers to a log file without .map available information at execution;
  • exception logging (Delphi or low-level exceptions) with unit names and line numbers;
  • optional stack trace with units and line numbers;
  • methods or procedure recursive tracing, with Enter and auto-Leave;
  • high resolution time stamps, for customer-side profiling of the application execution;
  • set / enumerates / TList / TPersistent / TObjectList / TContainer / dynamic array JSON serialization;
  • per-thread or global logging;
  • multiple log files on the same process;
  • integrated log archival (in zip or any other format);
  • Open Source, works from Delphi 6 up to XE.
