Fix #6115 (Add support to realloc to cfg files) ( #1953 )
...
* 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.

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 Token default constructor
* Switched to using default constructor for Token
* Added missing argument to Token constructor
* Changed to use default constructor for Tokens
* Switched to using default constructor for Tokens
* Switched to using default constructor for Token
* Added new test for deleting front Token
Also made sure to use the correct constructor for Token in other tests.
* Syntax error
* Replaced tokensFront and tokensBack with a struct
This decreases the size of the Token class for performance purposes.
* Replaced tokensFront and tokensBack with a struct
* Added tokensFrontBack to destructor
* Reworked to use TokensBackFront struct
Also ran astyle.
* Reworked to use TokenList's TokensFrontBack member
* Reworked to use TokensFrontBack struct
* Reworked to use TokensFrontBack struct
* Reworked to work with TokensFrontBack struct
* Removed unnecessary scope operator
* Added missing parentheses
* Fixed syntax error
* Removed unnecessary constructor
* Default constructor now 0-initialises everything
This is safer for not using a temporary TokensFrontBack object, and doesn't use delegating constructors which aren't supported yet.
* Fixed unsafe null check
* 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.
Fixed if statement that was supposed to be adding safety but would actually cause a crash if tokensFrontBack was null.
* Fixing stylistic nits
Removed default constructor and replaced it with a single-argument constructor with a default value.
* Fixing stylistic nits
Renamed _listEnds to _tokensFrontBack.
* Fixing stylistic nits
Renamed _listEnds to _tokensFrontBack.
