这是典型的复制粘贴错误:
如果复制粘贴了一些包含带有 GUID 的接口声明的 Delphi 代码,Delphi 将不会抱怨和编译在不同地方重用相同 GUID 的代码。
“支持”功能基于其 GUID 与接口一起使用,因此可能会出错。
是否有可用的“质量保证”工具(可能是 Peganza 或 Delphi Sonar 插件)可以检测到它们?
仅适用于最新版本的 Delphi。您可以使用以下代码在运行时检测到这一点:
unit uInterfaces.Duplicates;
interface
uses
System.Rtti,
Spring,
Spring.Collections;
type
/// <summary>
/// Class allows to list the interfaces which are not implemented by any class in your module.
/// </summary>
InterfacesWithDuplicateGUID = class
private class var
/// <summary>
/// Reference to the RTTI context.
/// </summary>
FCtx: TRttiContext;
public
/// <summary>
/// Function returns the list of interfaces with duplicate GUID.
/// </summary>
/// <param name="AFilter">
/// A filter predicate for types to process.
/// </param>
class function Map(AFilter: TPredicate<TRttiInterfaceType> = nil): IMultiMap<TGUID, TRttiInterfaceType>;
class constructor Create;
class destructor Destroy;
end;
implementation
uses
System.TypInfo;
{ InterfacesNotImplemented }
class constructor InterfacesWithDuplicateGUID.Create;
begin
FCtx := TRttiContext.Create;
end;
class destructor InterfacesWithDuplicateGUID.Destroy;
begin
FCtx.Free;
end;
class function InterfacesWithDuplicateGUID.Map(AFilter: TPredicate<TRttiInterfaceType> = nil): IMultiMap<TGUID, TRttiInterfaceType>;
var
LType: TRttiType;
LIntf: TRttiInterfaceType;
LTypes: IList<TRttiInterfaceType>;
begin
{ Create the result instance }
Result := TCollections.CreateMultiMap<TGUID, TRttiInterfaceType>;
{ Get all the types }
LTypes := TCollections.CreateList<TRttiInterfaceType>;
{ Build the multimap }
for LType in FCtx.GetTypes do
{ Add only classes and interfaces }
if LType.TypeKind = tkInterface then
{ Skip interfaces which does not have GUID }
if TRttiInterfaceType(LType).GUID <> TGUID.Empty then
begin
{ Handle user filter }
if Assigned(AFilter) then
if not AFilter(TRttiInterfaceType(LType)) then
Continue;
LTypes.Add(TRttiInterfaceType(LType));
end;
{ For all interaces }
for LIntf in LTypes do
if LTypes.Any(
function (const AType: TRttiInterfaceType): Boolean
begin
Result := (AType.GUID = LIntf.GUID) and (LIntf.QualifiedName <> AType.QualifiedName);
end) then
Result.Add(LIntf.GUID, LIntf);
end;
end.
当然,如果它符合您的需求。因为将其包含到生产代码中并不是最好的主意。但是可以包含在测试代码中。
如果你在 unix/mac 上试试这个 - 或者你的电脑上有cygwin
find . -name '*.pas' -exec awk "/\['{.*}'\]/ {print $1}" {} \; | sed 's/ //g' | sort | uniq -d
然后找到单独的重复项
find . -name '*.pas' -exec grep -i -l 'XXXX-XXX-XXX' {} \;
在mac上测试
