EurekaLog 7.8 is out

We are pleased to announce the availability of the new 7.8 version.

EurekaLog Logo
EurekaLog is a tool for Delphi and C++Builder that gives your application the power to catch every exception and memory/resource leak, generating a detailed log of the call stack (with unit, procedure and line number), optionally sending you a copy of each log entry via email or the Web via the most used Web Bug-Tracking tools (as Mantis, BugZilla, FogBugz, and JIRA).
EurekaLog represents the most advanced exception and memory leaks logger technology available for Delphi/C++Builder developers.

Important Note: Each modern EurekaLog installer supports IDEs starting with Delphi 5 and up to the latest IDE - about 19 IDEs in total.

Latest supported IDE is:
  • EurekaLog is compiled against RAD Studio 10.3.3
  • EurekaLog is compiled against RAD Studio 10.3.2
  • EurekaLog is compiled against RAD Studio 10.3.1
  • EurekaLog is compiled against RAD Studio 10.3.0 (RTM)
  • EurekaLog is compiled against RAD Studio 10.3 BETA

There are various binary incompatibilities between different 10.3.x builds. More info can be found here.

Changes in 7.8 build:

  6. Added: Interfaces information lookup for leaks and memory errors
  7. Added: Added stack frames recovery after FPO routine
  8. Added: New "Consecutive Processing" multi-threading option to replace various "Pause" options

  56. Fixed: Added workaround for OpenTools API issues when compiling projects via "Build All Projects" or Build Groups (only for RAD Studio XE and above)
  57. Fixed: Leaks checks performance optimizations
  58. Fixed: Wrong unit / routine may open in IDE when double-clicking on EurekaLog's call stack dialog when there are collapsed items
  59. Fixed: Possible crash in JIRA sender when custom fields contain invalid values
  60. Fixed: Call stack building for exceptions in routines with broken stack frame
  61. Fixed: Wrong address may be used in RAW stack dump

  82. Changed: Mem/Res leak add handler is converted to function. Now you can return False to indicate that leak was ignored
  83. Changed: Leaks checking will now stop collecting leaks info when it reaches 4 times of "Max leaks to report" option. This can cause to report less leaks than "Max leaks to report" - because other collected leaks may be removed later due to grouping (parent/child) or counting (same leaks)
  84. Changed: Added more internal logging
