* Removed redundant scope calculation
* Add scope propagation code to insertToken
* Add relevant scope code to Token class
* Add code to calculate the scope of Tokens
* Add calculateScopes method to class
* Add missing include for shared_ptr
Since the number of test files is larger than the number of lib files,
this only caused an extra harmless '\' being printed after the last
header file in lib.pri. If the number of test files would have been
smaller than the number of lib files, the generated lib.pri would have
been broken.
* Fix#9225 (Crash on valid C++14 code)
This only fixes the crash. Specialization of nested templates is still
broken.
* fix cppcheck warnings
* fixed another cppcheck warning
* Use library for memleak checks
Change memleakOnRealloc and leakReturnValNotUsed to use library
configuration instead of hardcoding "realloc".
In order to do so, some care needs to be taken when matching for a
reallocation function, since it can no longer be assumed that the input
to be allocated is the first argument of the function. This complicates
getReallocationType() and checkReallocUsage() but is necessary in order
to handle for example freopen() properly.
Also, refactor memleakOnRealloc check to reduce duplicated code when
checking "a" and "*a". When doing so, extending the check to look for
arbitrary number of "*" can be done for free (just change an if
statement to a while statement). Most likely, this is an unusual case in
real world code.
* Remove redundant whitespace in Token::Match()
* Run on simplified checks
* Fix cppcheck warning
* Fix FP memory leak with unknown function call in condition
This was introduced in 8513fb81d2 when
fixing memory leaks for global variables allocated in condition. The
refactored code had an inconsistency where c and c++ code behaved
slightly differently when `var` is NULL. This seemed to not have an
impact as the code was written prior to 8513fb81d2,
but when the same code was used for conditions, FPs were introduced.
The introduced FPs were memleak warnings when there should have been an
information message about missing configurations for code like
void f() {
char *p = malloc(10);
if (set_data(p)) {}
}
Fix this by always returning true if varTok->Variable() is NULL for
both c and c++ code.
* Improve function name
This will diagnose more issues such as:
```cpp
void f(std::vector<int> &v) {
auto v0 = v.begin();
v.push_back(123);
std::cout << *v0 << std::endl;
}
```
* Fix adding unescaped slash token when splitting gcc case range.
Construction like case '!'...'~' converted to a list of separate case
tokens. When slas '\' symbol appears as a part of this list it was added
"as is", but it should be escaped like '\\' to be valid c++ code.
* Add test for switch-case range with slash
* Fix#9097 (Crash on thousands of "else ifs"s in gcc-avr package)
* increase recursion count maximum to 512 because cppcheck was hitting the 256 limit
* 512 was too much for windows
* Refactor Tokenizer::simplifyUsing to use continue to reduce indentation
added function findTemplateDeclarationEnd to skip template declarations
to reduce duplicate code
* fix travis build
This switches to use lifetime analysis to check for assigning to non-local variables:
```cpp
class test
{
public:
void f()
{
int x;
this->ptr = &x;
}
protected:
int *ptr;
};
```
* Partial fix for #9191 (simplifyTypedef: Problem when namespace is used)
This fixes simplifyUsing which has the same problem as simplifyTypedef.
simplifyUsing was designed to support using namespace but it was never
implemented. The changes are minor to add it.
simplifyTypedef requires much more work to support using namespace.
* reduce scope of variable
* make idx const
* Allow to configure realloc like functions
* memleakonrealloc: Bring back tests.
The old memleak checker was removed, and the tests for it was removed in
commit 9765a2dfab. This also removed the
tests for memleakOnRealloc. Bring back those tests, somewhat modified
since the checker no longer checks for memory leaks.
* Add realloc to mem leak check
* Add tests of realloc buffer size
* Configure realloc functions
* Add test of freopen
* Allow to configure which element is realloc argument
* Fix wrong close in test
cppcheck now warns for this
* Update manual
* Update docs
* Rename alloc/dalloc/realloc functions
Naming the member function realloc caused problems on appveyor. Rename
the alloc and dealloc functions as well for consistency.
* Change comparisson order
* Remove variable and use function call directly
* Create temporary variable to simplify
* Throw mismatchError on mismatching allocation/reallocation
* Refactor to separate function
* Fix potential nullptr dereference
As pointed out by cppcheck.
* Overlapping sprintf, improve handling of casts
If there is a cast of the argument buffer, cppcheck would print out the
expression including the cast, which looks a bit strange to talk about
Variable (char*)buf is used as...
Instead, only print the variable name without the cast.
Also, handle arbitrary many casts (the previous code only handled one).
Multiple casts of the input arguments is probably an unusual case in
real code, but can perhaps occur if macros are used.
* Fix printing of variable
... and add a test.
* Simplify testcase
* Update symbol database such that the override keyword implies that the function is also virtual
* Add test case for implicit override
* change isVirtual to hasVirtualSpecifier
* fix method documentation for getVirtualFunctionCalls and getFirstVirtualFunctionCallStack
* Fix isImplicitlyVirtual to consider the override keyword and document logic
* Fix getFirstVirtualFunctionCallStack and getVirtualFunctionCalls to use isImplicitlyVirtual instead of isVirtual so new test case passes
* Fix#9047 (c-style casts before malloc)
Note that there are still no warnings for c++-style casts
* Fix memleak check with casts of assignments in if-statements
* Fix possible null pointer dereference
As pointed out by cppcheck.
* Add check of astOperand2 when removing casts
This is similar to how it is done in other checks.
Sources were built with Clang but with increased verbosity of error detection.
A number of syntax and semantic warnings were encountered. Commit adds
changes to correct these warnings.
Some changes involve removing extra, and unncessary, semi-colons at EOL
(e.g. at end of switch clause).
Project astyle settings are not currently setup to detect if a file is to
have an extra carriage return after the last line of data. Two files were
altered to ensure an extra carriage return.
An advisory to enhance code was encountered in triage code. Clang advisory
on a for-loop interation value suggested that:
`use reference type 'const QString &' to prevent copying`
Building with enhanced clang warnings indicated a large number of
instances with the warning:
`warning: zero as null pointer constant`
Recommended practice in C++11 is to use `nullptr` as value for
a NULL or empty pointer value. All instances where this warning
was encountered were corrected in this commit.
Where warning was encountered in dependency code (i.e. external library)
no chnages were made. Patching will be offered upstream.
Increasing the verbosity in Clang, warnings were produced that identified
differences in code and doxygen-formatted comments.
Corrections applied to silence warnings yet still convey intent of original comments.
* Added scopeinfo member to token class
Moved ScopeInfo2 declaration here as well because that's where it needs to be now.
* Added scopeinfo accessors and declaration to class
* Add new method for calculating scopes
This replaces the methods in the TemplateSimplifier which calculate the current scope as the token list is iterated. The old method required checking if the scope had changed for every token multiple times (for multiple iterations), which was surprisingly costly. Calculating scopes in advance like this decreases runtime on a worst-case file by around thirty percent.
ScopeInfo objects are disposed of when the TemplateSimplification is done as they are not used later.
* Add calculateScopes method to header
* Removed code that calculated current scope
This has been replaced by code that calculates the scopes up front and stores them with each token, which is much faster.
* Fixed compile errors from extra parentheses
* Added missing code to fix memory leak
* Added code to actually clean up ScopeInfo structs
* Tidy up a dodgy for loop
* Convert argument to const ref
* Calculate missing scopes
As the templatesimplificator expands templates and does multiple passes it needs to make sure all scopes are calculated.
* Remove copying the scope to the next token
This is now done properly when scopes are calculated.
* Remove call to calculateScopes
This is now done by the TemplateSimplifier.
* Recalculate scopes for every pass of simplifyTemplates
* Add code to calculate extra scopes as they are added
I thought that this might be useful for calculating scopes when Tokens are created, but as there are several ways of creating Tokens that don't guarantee that they are placed in a list it is easier to just calculate scopes when you know you have a list and when you know you're adding to a list.
* Fix several bugs and poorly designed code
Remove the global scopes collection, and clean them up instead by iterating through the tokenlist to find them. This means scopes can be calculated by functions in the Token class as well as in the Tokenizer class without leaking the scope object.
Fix a couple of bugs in the calculateScopes method and make it more efficient.
* Remove unnecessary calls to calculateScopes
* Move brace to correct position
Calculating scopes during insertToken only needs to happen if we created a new Token.
* Handle 'using namespace' declarations separately
This fixes a bug caused by a statement matching 'struct B < 0 > ;'
* Fix argument name mismatch
* Actually use newScopeInfo when inserting Token
* Switch to using shared_ptr to hold scopeInfos
This means ScopeInfo2 objects get properly cleaned up when they are no longer needed.
* Change ScopeInfo member to be a shared_ptr
* Update code to use shared_ptr
* Add missing include for shared_ptr
* Remove unnecessary cleanup code
This has been replaced by shared_ptr for ScopeInfo2 objects
* fix adding instantiation of first argument to an instantiation
* add support for function pointer template variables
* fix more cases where templates ending in ">>" are changed to end in "> >"
* fix travis build
* standard types can't be a template parameter name
* remove redundant level == 0 checks
* fix lambda in template variable
* fix a test
* lib: isNonBoolStdType no longer needed
lib/checkbool.cpp:50:13: warning: unused function 'isNonBoolStdType'
[-Wunused-function]
static bool isNonBoolStdType(const Variable* var)
* cmake: C++11 is required
also change instructions to a more common syntax
