Re: [cdt-dev] CDT Indexer Scalability

["Schorn, Markus" <Markus.Schorn@xxxxxxxxxxxxx>]

When you rebuild an index a brief statistics is written to the log (<workspace>/.metadata/.log).

If you need more details you need to trace your application. For that use the command line option

   -debug <options-file>

 

The available options can be found in the .options file contained in the ‘org.eclipse.cdt.core.jar’ file.

Hi,

 

I missed the hint from Achim's email for enabling indexer statistics J

 

Could someone explain how to enable these statistics?

 

Thanks a lot,

Yevgeny

I enabled indexer statistics thanks to the hint from Achim's email

Here is what I get for Mozilla:

C/C++ Indexer: Project 'mozilla' (5775 sources, 6617 headers)
   Options: indexer='PDOMFastIndexer', parseAllFiles=true,
     unusedHeaders=useDefaultLanguage, skipReferences=false, skipImplicitReferences=false, skipTypeReferences=false, skipMacroReferences=false.
   Database: 190164992 bytes
   Timings: 186188 total, 72622 parser, 12358 resolution, 37182 index update.
   Errors: 0 internal, 20665 include, 1125 scanner, 12344 syntax errors.
   Names: 990333 declarations, 4924443 references, 718561(10.83%) unresolved.
   Cache[45MB]: 247936670 hits, 130921(0.05%) misses.

Does that mean that I have 20665 unresolved includes and 718561 unresolved symbols ?

 

Yes, the message does mean that 20665 include statements were not resolved, which is a clear indication that the project setup was bad. The percentage of unresolved symbols (10.83) is also very high.
