Who owns a php exec tar extracted file?

it helps some times It appears the 267 is an "invalid directory" error.
Are you sure the Exec is pointing to the proper location?

[code]
function PrepareToInstall(var NeedsRestart: Boolean): String;
var
  ResultCode:   Integer;
begin
   if Exec(ExpandConstant('{app}\myapplication.exe'), 'quit', '', SW_HIDE, ewWaitUntilTerminated, ResultCode) then
   begin
      msgbox('True: C:\myapplication\myapplication.exe : ' + IntToStr(ResultCode), mbInformation, MB_OK);
   end
   else begin
      msgbox('False: C:\myapplication\myapplication.exe : ' + SysErrorMessage(ResultCode), mbInformation, MB_OK);      
   end;
end;

[code]
function PrepareToInstall(var NeedsRestart: Boolean): String;
var
  ResultCode:   Integer;
begin
   ExtractTemporaryFile('myapplication.exe'); 
   if Exec(ExpandConstant('{tmp}\myapplication.exe'), 'quit', '', SW_HIDE, ewWaitUntilTerminated, ResultCode) then
   begin
      msgbox('True: myapplication.exe : ' + IntToStr(ResultCode), mbInformation, MB_OK);
   end
   else begin
      msgbox('False: myapplication.exe : ' + SysErrorMessage(ResultCode), mbInformation, MB_OK);      
   end;
end;

I hope this helps . The difference should be nothing in modern shells (both should be POSIX compatible), with some caveats: There are likely thousands of unique shell binaries in use, some of which are missing common features or simply buggy. Only the first version will behave as expected in an interactive shell, since the shell will close as soon as standard input gets EOF, which will happen once it finishes reading file. The while loop reads from FD 0 in both cases, making the exec pointless if the shell supports < redirection to while loops. To read from FD 9 you have to use done <&9 (POSIX) or read -u 9 (in Bash). exec (in this case, see help exec/man exec) applies the redirections following it to the current shell, and they are applied left-to-right. For example, exec 9<&0 < file points FD 9 to where FD 0 (standard input) is currently pointing, effectively making FD 9 a "copy" of FD 0. After that file is sent to standard input (both FD 0 and 9).
Run a shell within a shell to see the difference between the two (commented to explain):

$ echo foo > file
$ exec "$SHELL"
$ exec 9<&0 < file
$ foo # The contents of the file is executed in the shell
bash: foo: command not found
$ exit # Because the end of file, equivalent to pressing Ctrl-d
$ exec "$SHELL"
$ exec 9< file # Nothing happens, simply sends file to FD 9

it helps some times Owns (effective) shows numbers where replication factor is taken into account.
Thus in case of nodetool status keyspacetest it shows how much data with replicas each node is holding.

it fixes the issue Unity DI doesn't have a way to Dispose the objects when their lifetime has finished, and you cannot leave them there until the GC decides to collect them.
Theoretically there are DI frameworks that implement the Register/Resolve/Release, and Release would be the place to call dispose, but Unity doesn't implement the Release part. I don't know if there are other frameworks which can do that in .NET.

using(var ctx = container.Resolve<MyDbContext>())
{
}

using(var ctx = DbContextFactory.GetContex())
{
}

public class DbContextFactory : IDbContextFactory
{
   public DbContext GetDbContext()
   {
      ...
   }
}

public MyService(IDbContextFactory dbContextFactory)
{
}

public class DbContextFactory : IDbContextFactory
{
   public IDbContext GetDbContext()
   {
      ...
   }
}
