Matthias Krüger e187fdb696 tokenlist::iscast(): save a few pointer dereferences. 2018-06-02 13:19:22 +02:00
rebnridgway 42a65c5160 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Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.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.

PKEuS ec1bd420a7 Refactorizations optimizing std::string usage:
1) Added global static const std::string emptyString; object:
-> Replaces some static variables in functions which might be not threadsafe
-> Avoids constructor call (std::string::string(""))
-> Even functions that return an empty string in some branches can return by reference now.
Added to config.h to ensure that it is available everywhere

2) Added overloads for TestFixture::assertEquals for the most common use cases:
-> Moves conversion from const char[] to std::string into a function, reducing code duplication in binary.

2014-06-24 17:42:39 +02:00
PKEuS 8b9daadd25 Replaced static variable isCPP in Token (was not threadsafe):
- Encapsulate parameters passed through AST compiler functions in a struct
-> Reduces maintenance overhead when changing them
-> Contains parameter indicating if the file is C or C++
- Added eKeyword Token type (at the moment, only true for C++ keyword "delete", but should be set for other keywords as well)
