--------------------------------------
Summary: NAnt release build is not optimized
Key: LOG4NET-508
URL: https://issues.apache.org/jira/browse/LOG4NET-508
Project: Log4net
Issue Type: Bug
Components: Builds
Affects Versions: 1.2.15
Environment: Windows 10 1511 x64
NAnt 0.92
Visual Studio 2015 Update 1
Reporter: Manuel Pallier
Priority: Minor
When looking through the log4net assembly with the Red Gate .NET Reflector I
noticed that the downloaded release assembly contains the
'DisableOptimizations' flag in the Debuggable assembly attribute. Further
analysis showed the following things:
1. Dowloaded binary in log4net-1.2.15-bin-newkey.zip (net\4.5\release
subfolder):
a. Size: 298 KB
b. 'DisableOptimizations' and 'IgnoreSymbolStoreSequencePoints' flags in
assembly attribute.
c. IL Code is not optimized (nop statements are present)
2. Own build using NAnt 0.92 and build.cmd, file output from bin\net\4.5\debug:
a. Size: 298 KB
b. All flags in the DebuggableAttribute are as expected for a debug build.
c. IL Code is not optimized (nop statements are present)
3. Own build using NAnt 0.92 and build.cmd, file output from
bin\net\4.5\release:
a. Exactly the same as the downloaded binary.
4. Own build using Visual Studio 2015 Update 1 in Debug configuration:
a. Size: 288 KB
b. All flags in the DebuggableAttribute are as expected for a debug build.
c. IL Code is not optimized (nop statements are present)
5. Own build using Visual Studio 2015 Update 1 in Release configuration:
a. Size: 256 KB
b. All flags in the DebuggableAttribute are as expected for a release build
(only 'IgnoreSymbolStoreSequencePoints').
c. IL Code is optimized
In my opinion 1b and 1c are bugs (and of course 3, since it's the same build).
An optimized (release build) assembly should not have a 'DisableOptimizations'
flag and should have optimized code (no nop statements).
