Daniel Marjamäki 5d1b4e6dbb Tokenizer: Remove redundant '+' 2012-11-28 07:09:56 +01:00
Frank Zingsheim f23ce8d254 Fixed #4180 (false positive: (style) Variable is assigned a value that is never used (inside loop)) 2012-11-28 06:11:33 +01:00
Daniel Marjamäki 4e92f8dfcd Fixed #4295 (False positive: Expression '(X & 0xFF00000000000000LL)==0xa00000000000000' always evaluates to false (64-bit value)) 2012-11-27 17:37:49 +01:00
Edoardo Prezioso f3029ce6bb Fixed a bug in Tokenizer::simplifyKnownVariables.
When we find constant variables, check if there's a usage of its reference in the code (for example: don't simplify 'f(&x)' to 'f(&100)').
2012-11-26 17:06:52 +01:00
Robert Reif bbc1747919 Fixed #3702 (False negative: fail to detect constructor implementation with slightly different (irrelevant) signatures) 2012-11-26 16:34:44 +01:00

Differentiate between the new cppcheck:r variables by appending a number to the name, like 'cppcheck:r1', 'cppcheck:r2' and more.

Robert Reif ffe657128f Fixed #4364 (Segfault in CheckStl::stlBoundries) 2012-11-20 06:12:14 +01:00
Edoardo Prezioso e0c10efdce Add a 'prepend' bool option to Token::InsertToken.
If it's true, add a new token before this. Except when this is the first one in the list, because there's not a way to update the list.front (I noticed some Token functions can potentially delete the list.front(), I don't know which effects does it cause).

PKEuS e5ebb49312 Added support for sizeof(wchar_t). Improved <Windows.h> type testing for Win64 platform. 2012-11-11 16:16:17 +01:00
PKEuS 5555e055f1 Refactorized <Windows.h> type support:
- Changed some more Win32 simplifications of wide-character/string types to use wchar_t
- Added support for LPWSTR
- Fixed test case to ensure that simplifications also work for Win32W
2012-11-11 15:40:06 +01:00
PKEuS 4ea2df8671 Changed handling of type wchar_t:
- Don't simplify wchar_t to unsigned short on Win32 platforms to ensure that checking of strings and nullpointer dereferences works.
- Added it as standard type
2012-11-11 14:47:16 +01:00
PKEuS 17b720ef7d Refactorization: Removed unnecessary code. Variable::typeStartToken() and Variable::typeEndToken() never point to "const".
Ran AStyle
2012-11-11 13:32:19 +01:00
PKEuS 704f285c90 Refactorized CheckStl::pushback():
- insert(), reserve() and clear() also invalidate iterators
- Properly support return and throw statements: Bailout after semicolon
- "." is also bad usage of invalid iterator.
2012-11-11 13:03:58 +01:00
Jose Roquette e8d3a4300d Fixed #4197 - False negative: invalidIterator2 not detected 2012-11-11 12:01:52 +01:00

2012-11-10 19:53:20 +01:00
PKEuS 3e03838025 Fixed verbose messages in CheckOther::incorrectLogicOperatorError which didn't contain all information of the short message. 2012-11-10 11:31:36 +01:00
PKEuS f75826c3e2 Added wstring to pattern where I forgot in bbe06c65c0 2012-11-09 20:25:50 +01:00
PKEuS 58fe7105f4 Remove C++11 keywords "override", "final" and "constexpr" 2012-11-09 19:53:10 +01:00
PKEuS ce961578c2 New checks (inconclusive): Suspicious calculation with sizeof()
- Check for sizeof(ptr)/something: This indicates that programmer was trying to calculate array size, but sizeof(ptr) doesn't return the length of the memory area, but size of a pointer.
- Check for sizeof()*sizeof(): This indicates that programmer misunderstood what sizeof() does: It does return the length in bytes of the given variable, not e.g. the number of elements in an array.
2012-11-09 18:08:20 +01:00
Edoardo Prezioso 119ab519a4 Support GNU extension of '?:' operator:
"x ? : y" is equivalent to "x ? x : y". I found a lot of code with this extension, probably we should warn a user to not use this.
2012-11-08 17:49:43 +01:00
Edoardo Prezioso 9556634ee7 Revert 1c0617c504. 2012-11-07 18:34:25 +01:00
Edoardo Prezioso 061a5e1ad7 Run astyle. 2012-11-07 02:24:46 +01:00
Edoardo Prezioso 1c0617c504 change some Token::Match patterns used in code:
replace '||' with '%oror%', where possible.
2012-11-07 02:23:09 +01:00
PKEuS aa2ad41629 Print message "Found calculation inside sizeof()" also for increment/decrement operator. 2012-11-06 11:39:47 -08:00

Edoardo Prezioso ca2a6e6054 Add '%char%' as a CheckInternal known pattern. 2012-11-05 17:25:36 +01:00
Edoardo Prezioso 63307c5db2 Remove the now useless fix for #4245.
The fix for #4276 made completely useless that branch, so remove it until someone shows a testcase which breaks this commit.
2012-11-05 00:13:04 +01:00
Edoardo Prezioso 7293fcfa9b Remove redundant code in simplifyVarDecl:
TokenList::insertTokens adds the missing braces links when needed. The function does not add links to '<>', though, hence the TODO.
2012-11-05 00:12:22 +01:00
Edoardo Prezioso 4e25ffa948 Remove unexecuted branch in duplicateTypedef:
If the code is intended to be used, please revert + provide a valid testcase.
2012-11-04 23:03:14 +01:00
Edoardo Prezioso 333711ae4f Remove dead branch in simplifySizeof:
the code in that branch won't ever be executed because simplifySizeOf is called after arraySize, which adds the string length inside the '[]' parenthesis.
2012-11-04 22:41:38 +01:00
Edoardo Prezioso 24bf6f99e1 More simplifyRedundantParenthesis changes:
simplify also '( var . var . ... . var )' parenthesis.
2012-11-04 22:38:18 +01:00
Edoardo Prezioso b6b359d1c6 Tokenizer::simplifyRedundantParenthesis refactor:
Change useless 'while' to 'if' where possible; unify duplicate 'delete [| ]| var' handling code.
2012-11-04 20:51:40 +01:00
Edoardo Prezioso 93f1fed205 Tokenizer '?:' handling code refactorization:
move '=|,|(|[|{|}|;|case|return (%bool%) ?' code handling from simplifyConditionOperator in simplifyConstTernaryOp in order to use a more efficient code, thus to remove code duplication.
2012-11-04 19:18:11 +01:00
Edoardo Prezioso 18e1eb7c70 Add missing hunks in the previous commit. 2012-11-04 19:08:54 +01:00

Edoardo Prezioso 87c931b74b Add '%char%' as pattern to match in Token::Match.
All and only those single characters enclosed in "'" are accepted.

Andrew Martin 7c370ec873 Fixed #4305 (improve check: 'vector.size() < 1' should result in 'inefficient checking for '...' emptiness.') 2012-11-04 16:15:26 +01:00

Daniel Marjamäki 24e71c479c Fixed #4301 (htmlreport broken) 2012-11-03 11:25:40 +01:00
PKEuS a36e008967 Fixed #4314: Using CheckNullPointer::isPointerDeRef() here is overkill and doesn't work as intended, since this function is designed to return 'false' if it isn't sure. 2012-11-03 10:25:32 +01:00
Edoardo Prezioso c9e0089546 Change Tokenizer member function name.
From 'simplifyQuestionMark' to 'simplifyConstTernaryOp' (the older name was not clear). Adjusted the doxy comment.
2012-11-02 14:57:12 +01:00

Edoardo Prezioso 39a5768e9d Fixed cppcheck message found in lib:
[lib/checkmemoryleak.cpp:869]: (style) The scope of the variable 'realloc' can be reduced.
And since realloc is never used, for now I commented all the lines where 'realloc' is declared/used.
2012-10-25 14:05:53 +02:00
Edoardo Prezioso 8271d63744 Forgot to fix another clang analyzer message.
