- implemented the backend for dynamic arrays. Still needs thorough testing but it should be complete. - use a memory arena to store flat pointers so that the messed up cleanup can be avoided by deallocating this in bulk. - added a new SO opcode to the VM to execute a write barrier. This is necessary for all objects that are not linked into one global table, i.e. everything except thinkers and class types. - always use the cheaper LOS opcode for reading pointers to classes and defaults because these cannot be destroyed during normal operation. - removed the pointless validation from String.Mid. If the values are read as unsigned the internal validation of FString::Mid will automatically ensure proper results.

- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

- added automatic type deduction capabilities for local variables. If you type 'let variable = value;' the type of 'variable' will be deduced from the given value. This is mostly of interest for type casting pointers, because 'let p = Classtype(objectvar);' does not require writing the class type name twice.

PPointer *TypeFont;
- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility. - let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests. - the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

PStruct *TypeVector2;

- added per-channel access for color variables. However, since they are locally stored in registers, it required a minor bit of fudging for this case. - make sure that a PFunction's implementation is always initialized before starting the code generator.
2016-11-21 11:38:39 +00:00
PStruct *TypeColorStruct;
- scriptified Strife's coins. - added a String class to allow attaching methods to the builtin string type. This works by checking if the left side of the member accessor is a string and just replacing the tyoe in this one place, all the rest is automatic.

- disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared. Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility. - let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests. - the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

- added automatic type deduction capabilities for local variables. If you type 'let variable = value;' the type of 'variable' will be deduced from the given value. This is mostly of interest for type casting pointers, because 'let p = Classtype(objectvar);' does not require writing the class type name twice.

some groundwork for the implementation of dynamic arrays - created script exports for all relevant functions with all integral types. - created script side definitions for the underlying data types. - added a void pointer type so that the prototype for the pointer array can use a generic type every pointer can be assigned to.

TypeVoidPtr = NewPointer(TypeVoid, false);
- scriptified Strife's coins. - added a String class to allow attaching methods to the builtin string type. This works by checking if the left side of the member accessor is a string and just replacing the tyoe in this one place, all the rest is automatic.

TypeColorStruct = NewStruct("@ColorStruct", nullptr); //This name is intentionally obfuscated so that it cannot be used explicitly. The point of this type is to gain access to the single channels of a color value.
- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

- allow defining native fields through scripts. Internally this only requires exporting the address, but not the entire field. - added new VARF_Transient flag so that the decision whether to serialize a field does not depend solely on its native status. It may actually make a lot of sense to use the auto-serializer for native fields, too, as this would eliminate a lot of maintenance code. - defined (u)int8/16 as aliases to the byte and short types (Can't we not just get rid of this naming convention already...?) - exporting the fields of Actor revealed a few name clashes between them and some global types, so Actor.Sector was renamed to CurSector and Actor.Inventory was renamed to Actor.Inv.

- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function.

- restrict 8 and 16 bit integer types to struct and class members - and I am not really sure if they should even be allowed there, aside from legacy readonly properties. For 32 bit floats the same would hold, but those are already mapped to 64 bit doubles silently. ZDoom only uses these types in a very few isolated places, and even those can be removed without problems, so it's very doubtful that having support for these types is of any benefit - on the other hand, having them will most likely introduce more code than is saved in the data by using them...

Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

Still needs thorough testing but it should be complete. - use a memory arena to store flat pointers so that the messed up cleanup can be avoided by deallocating this in bulk. - added a new SO opcode to the VM to execute a write barrier. This is necessary for all objects that are not linked into one global table, i.e. everything except thinkers and class types. - always use the cheaper LOS opcode for reading pointers to classes and defaults because these cannot be destroyed during normal operation. - removed the pointless validation from String.Mid. If the values are read as unsigned the internal validation of FString::Mid will automatically ensure proper results.

PName::PName()
- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility. - let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests. - the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility. - let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests. - the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

IMPLEMENT_POINTERS_START(PEnum)
- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

- disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared. Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

- removed the sequential processing of JSON objects because the benefit is too small. After testing with a savegame on ZDCMP2 which is probably the largest map in existence, timing both methods resulted in a speed difference of less than 40 ms (70 vs 110 ms for reading all sectory, linedefs, sidedefs and objects). This compares to an overall restoration time, including reloading the level, precaching all textures and setting everything up, of approx. 1.2 s, meaning an increase of 3% of the entire reloading time. That's simply not worth all the negative side effects that may happen with a method that highly depends on proper code construction. On the other hand, using random access means that a savegame version change is only needed now when the semantics of a field change, but not if some get added or deleted. - do not I_Error out in the serializer unless caused by a programming error. It is better to let the serializer finish, collect all the errors and I_Error out when the game is known to be in a stable enough state to allow unwinding.

- do not declare PNamedType::Outer as DObject. Ultimately we may have to get a fully qualified name out of this, so Outer should be a type that can handle this feature. The new class for this is currently used as base for PType and PSymbol so that PNamedType inherits from it and maybe later a namespace symbol can, too.

- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

Otherwise it would not be possible to reference a prototype during compilation of the function because it does not exist yet. * Give the variant a list of the function's argument's names, because these are also needed to compile the function. * create an anonymous function symbol when the function gets registered to the builder. At this point we have all the needed information to set it up correctly, but later this is no longer the case. This is the most convenient info to have here because it contains everything that's needed to compile the function in the proper context, so it has to be present when starting compilation. * added some preparations to implement special handling for weapons and custom inventory items, which can run action functions in another actor's context. This part is not active yet but the basics are present in SetImplicitArgs.

- disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared. Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

TypeTable.Clear();
- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

Unlike its native counterpart the script-side iterator is wrapped into a DObject to allow proper handling for memory management. - fixed: The VMFunctionBuilder only distinguished between member and action functions but failed on static ones. - fixed: FxAssign did not add all needed type casts. Except for purely numeric types it will now wrap the expression in an FxTypeCast. Numeric handling remains unchanged for both performance reasons and not altering semantics for DECORATE. - exported all internal flags as variables to scripting. They still cannot be used in an actor definition. - make ATAG_STATE the same as ATAG_GENERIC. Since state pointers exist as actual variables they can take both values which on occasion can trigger some asserts. - gave PClass a bExported flag, so that scripts cannot see purely internal classes.

- changed handling of duplicate classes in DECORATE. Instead of replacing the original, the second class will get renamed now, using the originating file as an identifier. In the vast majority of cases this should do exactly what is needed: Create an unconflicting second class that can coexist with the original. Unless the class is used by name this should eliminate all problems with this, but so far I haven't seen anything that used them by name. This is choosing the lesser of two evils. While some mod out there may get broken, the old setup meant that the first class of a given name could not be written out to a savegame because it was not retrievable when loading it back.

- removed an assert from APowerMorph::EndEffect. With some recent changes to DestroyAllInventory it appears that the asserted condition no longer is true at this point when ending a game. - fixed: When replacing a tentative class, the pointers in the morph objects were not replaced. Instead of adding more ReplaceClassRef methods I chose to integrate this part into the PointerSubstitution mechanism and delete ReplaceClassRef entirely. The code had some oversights anyway that would have caused problems, now that non-actors can be created.

- changed PClass:AddField so that it doesn't create defaults if none are present. The ZScript compiler will not create any defaults until after all fields have been added and this function created bad data if it was run on a class without defaults. - added checks for duplicate field names. - moved the tree node symbol tables out of PSymbolTreeNode to the worker data. That symbol is a bad location because it restricts the usefulness of the symbol class which is also needed for variables which use different AST structs. - fixed some memory management issues with the work classes for the compiler that became apparent after moving the symbol tables in there. In several places these were copied around, possibly losing data.

- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

- fixed: Class and struct name lookup was not context aware. If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files. Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed. Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values. Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class. Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore. - made PEnum inherit from PInt and not from PNamedType. The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.
