self_update

hello world.

I am trying to do a self updating script.  I see several examples which use a batch file and taskkill to end the current script and copy the new one.  however, with windows 7 the batch file has to run with elevated rights to taskkill the process successfully and the user running the script may not necessarily have those rights.

has anyone found another way to get around this?

thanks =>

Is it necessary to update the running script?

You should separate data and code. Data should be changeable by the user, code changes should only be made and tested by a coder/scripter/programmer.

Can you describe your problem in more detail?

there really isnt data.. so the script changes reflect bug fixes or enhancements to the functionality.

i think i may have thought of a way.

Func Check_Updates()
 
$remote_version = FileGetVersion($tools_dir & "\" & @ScriptName)
$local_version = FileGetVersion(@ScriptFullPath)
 
$compare_versions = _VersionCompare($local_version, $remote_version)
 
If Not @error Then
If $compare_versions = -1 Then
Get_Update()
EndIf
EndIf
 
EndFunc   ;==>Check_Updates
 
Func Get_Update()
 
$remote_file = $tools_dir & "\" & @ScriptName
 
$script_name = StringReplace(@ScriptName, ".exe", "")
$script_name = StringStripWS($script_name, 8)
$batch_file = @TempDir & "\update_" & $script_name & ".cmd"
 
If FileExists($batch_file) Then
FileDelete($batch_file)
EndIf
 
$command = '@echo off' & @CRLF
$command &= '' & @CRLF
$command &= 'ping localhost -n 5 > nul' & @CRLF
$command &= 'del /f /q "' & @ScriptFullPath & '"' & @CRLF
$command &= 'copy /y "' & $remote_file & '" "'& @ScriptFullPath & '"' & @CRLF
$command &= @ScriptFullPath & @CRLF
$command &= 'del %0'
 
FileWrite($batch_file, $command)
 
Run($batch_file, @ScriptDir, @SW_HIDE)
 
_Exit()
 
EndFunc   ;==>Get_Update

Better idea would be to have a separate script that downloads the updates and then copies the files to the installation location. Run the update script, and exit the current script right after you do that. Then you don't need to force close the main script as it's already closed.

where would the seperate script reside?  copy it to the pc using fileinstall and just leave it there?  thats an idea too..

That would be a simple and reliable way to solve your problem.

If needed you could delete the update script if no update is needed. So no traces are left on the users PC.

self delete?  thats through batch file tho right?  need the elevated rights to taskkill it first?

or

delete through parent script.  and only delete it if theres no updates - otherwise let it linger on their pc ;-)

The idea is:

Check if an update is available

If yes:

  • Fileinstall the Update script
  • start the update script
  • exit the main script
  • Now the update is being done by the update script
  • call >_SelfDelete to delete the update script

There are other SelfDelete solutions available that simple write a BAT file to disk, call this bat file and exit.

Shouldn't need elevated permissions.

Your _SelfUpdate uses TaskKill which needs elevated permissions which isn't possible for gcue according to his OP.

Here's what I do if it helps at all :)

I have an installer, packed in the installer is the main script.

The main script (when installed) can search for updates by downloading a txt file in my dropbox and comparing the current version with the last version listed in my text file. 

If there is a newer version in the text file, the main program prompts a download.

The new download is the main program packed in an installer.

The installer (when run) ProcessCloses any instances of the main program running and extracts the new files.

Then it starts the (new) main program and exits itself.

Update done.

I do a version updating script here for our users for launching our in house web based accounting system and our legacy term window system.

I have two files, the launcher and an update script. I tossed a file (ini file which includes the versions of both on the network, just for information.  If this file exists I allow the script to version check both).  This allows me to remove this file to stop any updating if it goes bonkers.

On startup I check the local update.exe version against the server - this is just a filecopy.  I also check the launcher file against the server version, if the server one is new I copy it over to a temp name, launch the update.exe with a parameter (just so you can't run it by itself) and close out of the launcher.  When update.exe starts, it looks for the process that you pass to it, when that terms, It replaces the launcher file with the temp file it downloaded.  I cache the version in an ini file local as well so I can version compare to find out if it's first run, that way I can do first run versioning stuff (sometimes they download a new icon or I change an ODBC connection).

Works really well, i've done over a dozen version changes with no oddball behavior.

  • call >_SelfDelete to delete the update script

Why not

Parent fileinstall update script

parent close

update script updates

update starts parent

update script closes as parent sleeps for an amount of time (~200ms)

parent deletes update script

Or you could have the update script launch the parent script with a command line peram that tells the parent to delete it and then close, otherwise parent runs normally

hmm i am getting "update failed to download" (from updater script) approximately 1 out of 10 attempts.  in addition to the error, the parent script dissapears and the updater script remains.

the log shows the right paths as expected.  so based off the return values, the parent process is terminated successfully and the copy command fails twice.

makes sense that the updater file remains because it never goes through the self_delete function but dont understand why the parent script disappears.

if the copy fails when replacing a file, does it delete the original one anyway?
