Support floats in valid config ( #1297 )
...
* Add tests for invalid ranges
* Refactor loadLibErrors
This reduces the amount of code slightly and will simplify adding
more tests.
* Handle empty valid field
Before this change, the sequence <valid></valid> in a config file would
result in a segmentation fault. Now an empty field results in the error
message:
cppcheck: Failed to load library configuration file 'mycfg.cfg'. Bad attribute value '""'
* Add support for valid for floating point arguments
Previously, it was not possible to add valid ranges to floating point
arguments since it only handled integers. This made ranges not work well
for floating point arguments since arguments were cast to integers
before the ranges were handled.
Fix this by using doubles instead of integers if the argument is a float.
Add some tests for this and make sure errors are printed with enough
precision (somewhat arbitrarily chosen).
Note that it is still only possible to add integer ranges (i.e. -1:1).
* Add support for floats in configuration valid range
Now that it is possible to handle decimal arguments, there is no reason
to not allow non-integer ranges. Take care to not allow broken
configurations.
* Move check to within if-clause
* Move asin{,f,l} and acos{,f,l} input checks to config file

Fix crash bug #8579 ( #1238 )
...
* Added declaration for deletePrevious function
* Added definition for deletePrevious function
* Fixed crash from deleteThis invalidating pointers
The crash was caused by deleteThis() invalidating the pointer to a constant variable usage. This happened when a usage followed an assignment. This fixes bug #8579 .
* Added tokensFront to match tokensBack
This means deletePrevious can set the list's front if necessary.
* Initialised tokensFront in appropriate places
* Switched to using default Token constructor

* Switched to using default constructor for Token
* Added missing argument to Token constructor

* Added missing explicit keyword
* Fixing stylistic nits
Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.
Renamed listEnds to tokensFrontBack.

Optimised simplifyKnownVariables ( #1205 )
...
* Optimised simplifyKnownVariables
Changed the check for references to constant variables so instead of iterating through all tokens looking for references (which is very slow for large files), usages of each known variable are recorded so each usage can be checked for whether or not it is a reference. Just checking known usages is a lot quicker than checking through all tokens.
* Fixed test error caused by incorrect code
* Fixes to constant variable simplification optimisation
Indexing variables by varId is easier than by Token pointer, but means we also have to store a reference to the constant variable Token in another collection.
Switched to using unordered_map over map as it has slightly better find performance.
* Fixed incorrect simplification behaviour
This should remove constant variables correctly and efficiently. Requires additional functions, Token::deleteThisInPlace() and TokenList::front(Token*).
* Added setter for TokenList::first
This allows code that adds and removes Tokens from the list to do so without copying nodes into other nodes, which sometimes create difficulties.
* Added deleteThisInPlace function
This allows a token to delete itself without invalidating pointers to the node after it. If this token is the first or last in a list the calling code will have to remember to change the list's front or back.
* Added declaration for deleteThisInPlace()
* Removed premature MatchCompiler optimisation
* Added and removed some functions
Added declaration for deleteToken(Token*) which deletes a single token from the list
Removed public front(Token*) because it broke encapsulation
* Implemented deleteToken(Token*) function
* Removed 'delete this' from deleteThisInPlace
* Switched to using safer function
TokenList::deleteToken is better than calling straight into Token::deleteThisInPlace because it doesn't call delete this and doesn't break the TokenList's encapsulation.
* Replace constant variables in reverse order
This fixes the problem where you have two constant value assignment statements in a row. Replacing and deleting them in reverse order means we avoid the problem of deleteThis() potentially invalidating the pointer to the start of the next assignment statement
* Removed unneeded and unsafe deleteThisInPlace
* Removed unneeded and unsafe deleteThisInPlace

checkunusedfunctions.cpp: Fix files.txt parsing ( #1197 )
...
On Windows searching for the last colon finds the colon which is part of
the path of the source file (e.g. "C:/projects/a.cpp"). Thus the path is
saved incomplete. This fix searches for the second instead of the last
colon and uses the data after the second colon as the path of the source
file.

Add suppressions to the XML dump ( #1166 )
...
* Added parsing suppressions from dump xml.
* Added code to dump suppressions to an xml file
* Added declaration for dump function
* Suppressions will now be written to the xml file when a dump is requested
* Fixed syntax error
* Removed excess whitespace
* Fixed indentation to be consistent
* Fixed indentation to be consistent
* Fixed indentation to be consistent
* Added missing include for ErrorLogger::toXml
* Fixed suggestions from pull request #1166
Switched to using ranged for loop to iterate through suppressions.
Made the line number attribute optional, rather than 0 if not specified. This means when Python deserialises it it will be None, which is more pythonic.
* Implemented checking suppressions in reportError
This modification expects suppressions and a function to be called to write a line of output to be passed in. The function checks if any of the suppressions match the warning (with the new Suppression.isMatch function) and if so returns None. This change maintains the old behaviour of returning the warning text, but adds the possibility of returning None if the warning was suppressed.
* Fixed code quality warnings
* Removed more extraneous whitespace

Whenever simplifyFunctionParameters was called on a templated class'
templated member function (and probably any nested template), the
tokenizer would recognise it as a syntax error, assuming that return
type *must* come after a template<> token.

symboldatabase: Fix potential null pointer dereference ( #1072 )
...
There is a potential `nullPointer` dereference in symboldatabase. This PR attempts to fix this. Additionally, this could be detected by Cppcheck as well.
Here is a reduced and compilable testcase, where Cppcheck fails to detect a potential `nullPointer` dereference:
```
class Scope
{
public:
bool bar();
int *definedType;
};
int f(Scope *new_scope)
{
int ret = 1;
if (new_scope)
{
if (new_scope->bar())
{
if (!new_scope->definedType) {} // check for null
ret = *new_scope->definedType; // dereference
}
}
return ret;
}
```

construct is used in several libraries, i.e. Google Test.
