PKEuS 60cc8296c3 Fixed crash in checkmemoryleak.cpp reported by HeisSpiter 2012-03-17 11:34:27 +01:00
PKEuS fb4709f1be Refactorizations in checkmemoryleak:
- Replaced two indendation counters and one variable storage by symboldatabase functions
- Removed zero-element at end of two static arrays
- More accurate algorithm for finding a parameter by varid
- Replaced some simple tokens by direct string comparision
- Made some functions in checkmemoryleak.h private to improve encapsulation

Pierre Schweitzer 81318b3f4a Detect and display an error on leaks due to return of a function that allocates something is ignored.
This fixes #3439

Daniel Marjamäki 45759f6f7d CheckMemoryLeak: report debug warning when variable id is 0. Ticket #3527 2012-03-14 18:54:34 +01:00
Daniel Marjamäki 9df6088ddd Revert "really fix #3527 (Internal error. Token::Match called with varid 0. Please report this to Cppcheck developers)"
This reverts commit a37031944e.

I don't want this hard coding of macro names. Feel free to come with a more generic solution if you want.

PKEuS 167a7e3e51 Various code cleanups 2011-12-08 21:28:34 +01:00
Edoardo Prezioso 4de5d87078 1)Remove newly copy of 'eraseTokens' and replace every occurrence with 'deleteNext' with right parameter.
2)General improvements to code.
2011-12-08 01:44:18 +01:00
Edoardo Prezioso 612b3c59ca 1)Implement another declaration of 'Token::eraseTokens' with parameters: the starting token and the number of times needed to call 'deleteNext'.
2)Use the overloaded 'eraseTokens' where needed instead of using consecutively 'deleteNext'.
3)Tokenizer: general optimizations about the deletion of some tokens.
4)Run astyle.
2011-12-07 02:29:03 +01:00
Edoardo Prezioso c8bbb77776 CheckMemoryLeakInFunction::simplifycode : use properly 'deleteNext' instead of 'deleteThis' or 'eraseTokens' and remove redundant conversion to 'std::string'. 2011-12-05 15:50:11 +01:00
Daniel Marjamäki fb3115a199 Fixed #3267 (False positive: resource leak in vdr-xinelib) 2011-12-03 09:53:36 +01:00
Edoardo Prezioso 767413adad 1)internal check found a 'findmatch' with simple string argument;
2)Style: uniform 'while (...)' when inside it there's an assignment;
3)Replace '0' with 'NULL' where there's comparison with a pointer.
2011-12-01 12:04:47 +01:00
Edoardo Prezioso 1084e4bece 1) Shut up GCC compiler for 'missing braces around assignment';
2) Tokenizer::simplifyGoto: Code refactoring in order to skip code inside '()|[]' parentheses without counting.

Edoardo Prezioso a32b05197d Change every 'tokAt(1)' to 'next()' and every 'tokAt(-1)' to 'previous()'.
Added a safety check to ensure that a 'previous()' call doesn't crash (not sure if it's needed or not).
2011-11-20 15:59:37 +01:00
Edoardo Prezioso 11dd3c09ce Change every 'tokAt(1)->' to 'next()->' because 'tokAt(1) == 0' is equivalent to 'next() == 0', hence the equivalent cppcheck crash. 2011-11-20 15:09:57 +01:00
