Daniel Marjamäki d7be62a6f9 Fixed #3221 (FP: Array 'arr[2147483648]' index 0 out of bounds in loop when size unknown to cppcheck) 2011-10-29 20:26:24 +02:00
Daniel Marjamäki 24a2b6e6ba Fixed #3195 (operator() from a functor-struct is never used) 2011-10-29 20:04:43 +02:00
Thomas Jarosch 09bdacf31f FileLister (linux): Refactor code to keep only one list of seen directory entries 
The list contains filenames and directories now
and is only used for duplicate detection.

Thomas Jarosch a09011630d FileLister (linux): Handle cyclic symbolic links 
Keep a list of already seen directories.

The "udev" project f.e. has a directory with
a subdirectory that contains a symbolic link
back to the parent directory.

Thomas Jarosch 0f299aa9bf FileLister (linux): Move absolute path determination to own function

Daniel Marjamäki 316aa920eb Fixed #3245 (False positive: Dangerous usage of 'string' (strncpy doesn't always 0-terminate it)) 2011-10-29 19:11:42 +02:00
Richard Quirk a0a5b36667 Ensure single-argument constructors are explicit 2011-10-29 18:24:30 +02:00
Richard Quirk 2ca932a3ae Add checks for explicit constructors 
Single-argument constructors should be explicit. Constructors with
multiple arguments should not be marked explicit.

Marek Zmysłowski 950460c0a7 Fixed #3261 (Function 'find' useless call. The variable 'str' is using function 'find' against itself) 2011-10-29 09:24:05 +02:00
Edoardo Prezioso 5d868766c7 Tokenizer time improvements (time says real: -1 second) 
1)change tokAt(1|-1) with next()|previous() with conditions where necessary;
2)change strAt(1|-1) with next()|previous()->str() with conditions where necessary;
3)change tokAt(n)->str(), with n != -1,1, to strat(n);
4)change simplifyFuncInWhile implementation because it was too slow and stupid.
 2011-10-29 01:57:53 +02:00
Edoardo Prezioso dd719b41bf Definitely check correctly 'sizeof %num%' when '%num%' has '-' sign. 2011-10-29 00:11:38 +02:00
Thomas Jarosch dee03a09e4 Fix logic glitch 
Reported by Pc-Lint 9.x :o)

The code was working before as the AND operation
also matched in that specific case.

I verified that code is in use by commenting
it out and checked how many tests failed.

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!

Richard Quirk 665cdfabdc Warn when sizeof is used in strncmp ticket #2095 
This checks for the case where the user thought sizeof(buf) gave the
size in bytes of 'buf' in code like the following:

  const char *buf = "Hello World";
  strncmp(buf, other, sizeof(buf));

Edoardo Prezioso bab740289c Complete todo: convert 'for' into 'while'. 
It's not possible to enable this code because of the disaster it will be created for all the checks with the 'for' pattern.

Thomas Jarosch 22251d50bb Bugfix: Use Token::Match instead of Token::simpleMatch because it's a complex pattern

(And yes, I wrote a check for cppcheck's Token::Match invocation ;))
