卸载顺序

Question

我可以在某个地方找到实际顺序，卸载期间执行哪些事件和部分？例如，UninstallDelete 会早于usPostUninstall 卸载步骤吗？

Inno Setup 手册中有“安装顺序”一文，但它看起来更像是编译顺序，而不是执行。

Answer 1

卸载顺序与installation order相反，正如手册所说（实际上是安装顺序，而不是编译顺序）。

这仅仅是因为没有程序化的卸载顺序。安装程序将其步骤记录到卸载日志中，卸载程序只是以相反的顺序处理日志，没有任何更改顺序的选项。

event functions 适合如下卸载过程（仅显示主要卸载步骤）：

• CurUninstallStepChanged(usAppMutexCheck)
• InitializeUninstallProgressForm
• CurUninstallStepChanged(usUninstall)
• 处理卸载日志：
  • [UninstallRun]
  • 注册表项
  • 图标
  • 文件
  • 应用程序目录
  • [UninstallDelete]
• 第二次尝试删除目录（例如，之前不为空的目录）
• CurUninstallStepChanged(usPostUninstall)
• CurUninstallStepChanged(usDone)
• DeinitializeUninstall

我已经在一个简单的安装程序上对此进行了测试：

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program
DefaultGroupName=My Program
UninstallDisplayIcon={app}\MyProg.exe
OutputDir=.

[Files]
Source: "MyProg.exe"; DestDir: "{app}"

[Icons]
Name: "{group}\My Program"; Filename: "{app}\MyProg.exe"

[UninstallRun]
FileName: "{app}\MyProg.exe"

[UninstallDelete]
Type: files; Name: "{app}\test.dat"

[Code]

function InitializeUninstall(): Boolean;
begin
  Log('InitializeUninstall');
  Result := True;
end;

procedure InitializeUninstallProgressForm;
begin
  Log('InitializeUninstallProgressForm');
end;

procedure DeinitializeUninstall;
begin
  Log('DeinitializeUninstall');
end;

procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
begin
  Log('CurUninstallStepChanged + ' + IntToStr(Integer(CurUninstallStep)));
end;

卸载程序日志是这样的（它没有显示所有步骤）：
