Add more possible letters to simplifyInitVar patterns.
Replace 'tokAt(1)' with 'next()' and 'linkAt(1)' with 'next()->link()'.
Little optimizing improvements to simplifyAsm.

Edoardo Prezioso 4cad5d4df4 Workaround fixes to shut up some cppcheck '--inconclusive' whinings. 2011-12-13 00:24:34 +01:00
Edoardo Prezioso 81a2e62abd Tokenizer::simplifyGoto: fix another memory read error reported by Valgrind.
Also improvements to Tokenizer are done.
2011-12-12 22:03:25 +01:00
Edoardo Prezioso 79b82f115f Tokenizer: some changes to line numbers of some tokens:
simplifyAsm: change line number of newly added 'asm ( )' in order to be the same as next ';'.
simplifyIfAddBraces: Change line number of newly added '}' in order to be the same as next 'else', except for '{ ; } else'.

Edoardo Prezioso 626f13ae7e Tokenizer: Fix another Valgrind error in simplifyErrNoInWhile. Add more jumping patterns to simplifyIfAddBraces and simplifyDoWhileAddBraces. 2011-12-12 13:15:35 +01:00
Daniel Marjamäki 5f5c912f3f temporary fix for inconclusive false warnings. there is not sufficient logic for determining when there is NOT a pointer dereference. 2011-12-12 07:43:33 +01:00
Daniel Marjamäki 2dbe7ca196 CheckNullPointer::isPointerDeRef: Skip inconclusive checking when --inconclusive hasn't been given. 2011-12-12 07:35:53 +01:00
Edoardo Prezioso 99d8ce3732 Fix Valgrind error in arraySize():
if there's code like: 'int [ ] a = { 1 , 5 , }', 'end' is last '}', when 'tok2' arrives to second ',' and cppcheck finds out that next token to 'tok2' is '}', remove this ',' with 'tok2->deleteThis()' but it causes (maybe) a memory corruption to 'end' which will gave problems later because 'tok' will be assigned to it or its next token.
2011-12-12 02:23:49 +01:00
Edoardo Prezioso 52620e6493 Tokenizer::simplifyDoWhileAddBraces:
1)rewrite fix for ticket #988 (just don't simplify inside macro parenthesis);
2)use a different organization of the code: start from last token and proceed backwards. This way 'simplifyDoWhileAddBracesHelper' can be called just once, hence the 'Helper' code can be improved and moved in the main function.
2011-12-12 00:20:46 +01:00
Edoardo Prezioso cf574072b6 Tokenizer::arraySize(): improve code structure, fixed 'tok2' for-looping which didn't stop to the ending '}' parenthesis. 2011-12-11 23:13:37 +01:00
Edoardo Prezioso 3c098839d1 simplifyIfAddBraces: Remove restriction for jumping opening parenthesis '(' as a fix to #2873, because even without this the original test case doesn't crash anymore. Add more jumping patterns.
simplifyFunctionParameters: Add more jumping patterns and an observation related to error message for equal parameter names, help needed.
Fix grammar mistake in comment.

Edoardo Prezioso 27801b35eb Other improvements to tokenizer code.
Handle SQL code better, even when there's no ';' after 'EXEC SQL'.
simplifyVarDecl: Check with 'Token::Match' once when you have to check a pattern inside which there should be a number or a variable. Use '%any%' and after that check if that string is a number or a variable name later.
simplifyGoto: process also anonymous structs and unions which should have 'indentspecial' incremented, skip code like 'var = { ... }'.

Edoardo Prezioso 5f522fb841 Tokenizer: improve code and remove redundant checks.
In particular: improve 'double sharp' concatenation by handling also code which begins without the [{};]. Do the same with C# code. Also, in the labels simplification function, skip also '{}' when the open bracket is after a '='.

Richard Quirk a880469c5a Refactor the same expression check
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.

The pointer to symbol database and ref to list of const functions are
temporarily stored in  the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.

Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.

Whitespace was removed from the append data for every configuration
and every file: n(configuration) * n(files).

Removing whitespace immediately after the append data was read can
significantly reduce the execution time and memory usage.
It also allows further improvement because copies to the temporary
object appendCode are no longer needed.

This fixes false negatives for code such as:

the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.

Richard Quirk 2ca932a3ae Add checks for explicit constructors
Single-argument constructors should be explicit. Constructors with
multiple arguments should not be marked explicit.

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.

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.
2011-10-28 23:36:30 +02:00
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
