Drupal Answers is a question and answer site for Drupal developers and administrators. It's 100% free, no registration required.

I have some problem when using the "Update manager" on the GUI. Some directories get locked by php-cgi.exe, and thus the replacement of the original directories with the newly downloaded ones (which are fresher) is not successful.
BUT I have to mention that it's not a permission issue, because the modules can get installed via "Install from a URL" on /admin/modules/install, and work without a problem.

Let's take an example:

  1. Available updates page (/admin/reports/updates/update):

    Available updates

    Now I check Select (or other) module to be updated (it doesn't matter which module I choose, the results are the same!! so it's just an example).

  2. I hit "Download these updates" button.

  3. OK, the module's updated instance gets downloaded without a problem:
    "Updates downloaded successfully": Updates downloaded successfully
  4. Now I click on Continue.
  5. Here comes the error. The result:
    "Update failed! See the log below for more information.
    *select_or_other*
    • Error installing / updating
    • File Transfer failed, reason: Cannot copy D:/Projects/web/drupal-7/tmp/update-extraction-6d8993ac/select_or_other/LICENSE.txt to /Projects/web/drupal-7/htdocs/sites/all/modules/select_or_other/LICENSE.txt." Update failed!
  6. OK, I'm starting to try to inspect the possible reasons.
    • Here's what my Drupal directory structure looks like: TC directory structure. I set ../tmp to be the temporary directory (in /admin/config/media/file-system), the Drupal files are in htdocs. This is correct, as I can install modules via the GUI, as I mentioned above.
    • When I try to enter the htdocs/sites/all/modules/select_or_other directory, I can't, because I get an "Access denied on file ......sites/all/modules/select_or_other!" when opening in Total Commander, and "...sites/all/modules/select_or_other is not accessible. Access is denied" when opening in Windows Explorer: trying to open directory in Total Commander, trying to open directory in Windows Explorer
    • OK, I right click the folder, and open Unlocker via its assistant in the context menu. It says this directory is locked by php-cgi.exe: Unlocker - directory locked by php-cgi.exe I click on "Unlock All", and the folder can now get deleted of itself (as it's not locked anymore by php-cgi.exe), so it simply
    • I can find the updated select_or_other module's directory in tmp: updated module's directory in <code>tmp</code>
    • so I have to manually move it to sites/all/modules directory.

What can be the possible reasons of the lockup of the directory by php-cgi.exe? (Maybe Windows Cache Extension 1.1 for PHP 5.3 installed via Web Platform Installer? But if yes, why is that for example the deletion of images or similar via the GUI works correctly?)
What can I do to avoid this problem, and let "Update manager" work?

I'm seeing exactly the same behaviour with Drupal 7.15 on IIS7/2008R2. It would be great to fix this. –  Nic Aug 14 '12 at 20:45
    
@Nic: I agree! :) –  Sk8erPeter Aug 14 '12 at 22:31
    
I've seen this intermittently. Out of curiosity does refreshing your app pool unlock as well? –  Brent Sep 11 '12 at 18:54

I know it's off topic, but I have to say it - run away from Drupal on IIS. As I can see on the screenshots, you might be using it for local development. Check out WAMP or Acquia Dev Desktop. If you simply have to use it on a production server, ignore my comment :) I have to use IIS for certain sites and so far it hasn't been a good experience. –  Ivanhoe123 Sep 11 '12 at 19:17
    
@Brent: I don't know. After running a page in Drupal, the files and directories seem to get locked for an unknown period. By the way, I'm using Drush too, and when I want to update a module using drush up -y, I experience the same problem: I have to unlock these files and directories with Unlocker to make it work, otherwise I get the error message that these directories cannot be written/removed, and the update process gets interrupted. If I use Unlocker BEFORE running this process, the update is successful. –  Sk8erPeter Sep 11 '12 at 22:45
