Explicit constructors
2011-10-30 01:38:26 -07:00
Edoardo Prezioso 0bb1ad8782 Little improvements with cli messages and added new '--template' mode: 'edit'.

Thomas Jarosch f6e68914ea Add check for cppcheck's internal API usage (#3263)
First checks:
- Simple pattern used inside Token::Match()
- Complex pattern used inside Token::simpleMatch()

The checks get enabled by passing "--enable=internal".
It's not included in "--enable=all".

If you see something that needs further tweaking, just go for it!

Thomas Jarosch 55d9f0873a Fix #3243 (Improve non reentrant function check)
- Use std::map instead of linear std::list walk
  and run fast tests like tok->isName() first.

  Global speed up is 4.8% (profiled with google-perftools)

- Catch function invocations in global namespace
  and ignore other namespaces except "std".

  std::localtime() and others are also non-thread safe on POSIX.

  Note: The check matches f.e. also on "std::getrpcbyname()",
  but that would result in a compile error anyway.
  No need to have an extra "std::xxxxx" whitelist.

- Remove double listed "rand" and "getrpcbyname" function names
