Changed behaviour of Token::is*Op() functions:
...
- Rename Token::isOp() to Token::isConstOp() (indicating that the operator does _not_ modify the input variables)
- Create new Token::isOp(), returning true also for ++, -- and assignment operators
- Make Token::isExtendedOp() returning also true for all assignment and ++/-- operators

fix misspellings & gcc v3.4.6 warnings
...
1. fix typos / misspellings
- Fix misspelling within comments, variable/function names, stdout messages
- changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```. Alias old name (```stlBoundries```) to the new one.
2. fix gcc v3.4.6 32bit & 64bit warnings
- fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html

- in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others

Small refactoring to compile more matches
...
*** Timing of the test suite ***
Four runs were used to calculate the average run time.
Before: ~1,103s
After: ~1,066s
Speed up: 3,35%
*** Timing of internal projects using STL ***
Before: ~8,301s
After: ~8,207s
Speed up: 1,13%
So the real world speed up is roughly 1%.

- fix word misspellings (mostly comments, a few output lines)
- Parenthesis => Parentheses (both variations were used in the codebase)
- fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

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.

Change every 'tokAt(1)' to 'next()' and every 'tokAt(-1)' to 'previous()'.

2011-11-20 15:59:37 +01:00

Change every 'tokAt(1)->' to 'next()->' because 'tokAt(1) == 0' is equivalent to 'next() == 0', hence the equivalent cppcheck crash.

Fix for same expression separated by commas

The code branch tested by the previous check for && is now different, so
I've changed the test to use == instead. There was also a missing case
when the expression was followed by a comma instead of being preceded by
one.

Improved same expression check for ticket #3274
...
Expand the logic for the check for the same expression on both sides of
the || and && operators. Now expressions can be more complex, with the
"alt" variable helping to fudge operator precedence to avoid false
positives.

Move "information" errors to "style" errors.
...
"information" severity is documented in lib/errorlogger.h as:
Checking information.
Information message about the checking (process) itself. These
messages inform about header files not found etc issues that are
not errors in the code but something user needs to know.
It IS NOT for errors in the code. All the current "information"-
severity errors fit nicely into description of the "style"-
severity.
We definitely need to separate processing information and actual
errors in the code. It is highly confusing for users to mix these
two different things. Hence all current "information" code error
messages are moved to "style" category.
Ticket: #3165 (Stop misusing the 'information' error severity!)

Use "enabled" list for the style checking.
...
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.
Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.

Fixed #1132 (Detection of misused scope objects in functions)
...
Emits error in the form:
[useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately
...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.
Only checks for misused scope objects within functions.
Optimised isIdentifierObjectType() by memoizing.

Fixed #1132 (Detection of misused scope objects)
...
Emits error in the form:
[useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately
...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.
Removed "internal error" from token.cpp, since in this case varid would be NULL.

Redundant conditions: some refactorings
...
* removed the 'redundant null pointer' check. sometimes it's unsafe to delete NULL pointer. and this check doesn't point out errors anyway.
* moved the 'redundant condition' check for set::remove. Moved it to CheckStl.
2010-09-16 18:49:23 +02:00
