Summary18697: Importing resources in IIS doesn't work.

With the correct structure of the package, it is not possible to import resources, it always returns the message "This ZIP archive contains no valid Resources files. Import failed."

Steps To Reproduce

The main problem is in the PclZip library, firstly it adds './' to the beginning of the path - which is not correctly interpreted by WindowsServer.

The second serious problem is setting the paths to: images and files (they contain an incorrect directory separator) already at the level of the SurveyAdministrationController and the FilterImportedResources library.

For the reasons mentioned above, in the 'privExtractByRule' method, the files return the status "path_creation_fail".

Seems broken on 3.27.26 (yes, i know : need to update)

Export resource from same server.

I performed tests in LS v5.6.13 (pure instance, without our dedicated plugins).

  1. I added two files to resources as in the screenshot.
  2. I made an export to a ZIP file (I'm sending a package)
  3. I go to the survey, I import the package, I get the message "This ZIP archive contains no valid resources files. Import failed."

I performed the tests on a new survey, as well as on the same one after deleting the resources, I always get the message from point 3.

After performing the fixes below, the issue was resolved.

  1. In these files I changed "/" to DIRECTORY_SEPARATOR
  2. delete the line:
    Only with a change in the pclzip.lib.php file - this solves the problem on windows but for linux it will generate error

@2BITS_PL : can you create a pull request ?


The pclzip.lib.php update are mandatory ?

This line in the pclzip.lib.php file adds "./" to the beginning of the path, creating the path: "./W:\code...\tmp\qCWfoZSMUQfn0RdqUCqGfCUqT7i62Ge4" and Windows cannot interpret it correctly.

I don't know if it makes sense to prepare a pull request, since the proposed solution is not comprehensive.
The problem with pczlib is that in the function privExtractByRule it goes to the first condition and changes the path to something IIS doesn't understand.

I actually don't know how to fix pczlib because I don't know enough about the project structure. The proposed solution is not good as it will solve the problem for windows but will create one for unix systems.
Here you need to change this code to work equally on both systems. Unfortunately, this library has slashes declared in many places, which can be problematic for IIS because it expects backslashes.
