upgrade to Mapbender 3.2.2 release

[Jeff McKenna]

released today: ​https://lists.osgeo.org/pipermail/mapbender_users/2020-July/005813.html

[Jeff McKenna]

It seems that the entire directory structure was changed for this release, and the install docs still have not been updated for those changes (​https://doc.mapbender.org/en/installation/installation_windows.html), so this package update will have to wait.

[Jeff McKenna]

After trying to adjust to 3.2.0's new directory structure (/mapbender/web/ no longer exists, instead /mapbender/application/web/) and trying to load /app.php/ here are the errors:

Warning: require(D:\ms4w\apps\mapbender-starter-3.2.0\application\app/../vendor/autoload.php): failed to open stream: No such file or directory in D:\ms4w\apps\mapbender-starter-3.2.0\application\app\autoload.php on line 9

Using the correct archive for 3.2.0 (​https://mapbender.org/builds/mapbender-starter-current.zip) the demo app hangs forever and does not load, and the Apache log contains errors of "get overlap result error"

Milestone renamed

[Astrid Emde (WhereGroup)]

new Mapbedner configuration file for fcgi and mapbender 3.2.2

[Astrid Emde (WhereGroup)]

• added the new configuration file (see file attached)
• fixed fcgi-configuration
• reference to new mapbender 3.2.2.
• please download Mapbender 3.2.2 from: ​https://mapbender.org/builds/3.2.2/mapbender-starter-v3.2.2.zip

[Jeff McKenna]

I did much testing today on the MS4W build servers, unfortunately the same problems exist with the new FCGI settings in httpd_mapbender.conf (Internal Server Errors, or forever hanging)

I do notice that the changes work on 1 machine that doesn't have the usual read/write permissions on the C:/Windows/ directories.

Background: MS4W is specifically designed to not point to any "Windows" directories, to avoid write permission errors, "DLL hell" errors (same dll found in C:/Windows/System32 and inside MS4W causing crashes) etc. For example, MS4W also comes with its own writable "TMP" or "TEMP" directory, used by many applications: /ms4w/tmp/ms_tmp/

I will do more testing, avoiding any "WINROOT" or Windows path directories, with the new FCGI settings...

Thank-you so much for your feedback here (!!).

[Astrid Emde (WhereGroup)]

So maybe we change FcgidInitialEnv for the temp / tmp dir to /ms4w/tmp/ms_tmp/

FcgidInitialEnv TEMP "${WINROOT}/TEMP"
FcgidInitialEnv TMP "${WINROOT}/TEMP"

[Jeff McKenna]

Agreed, that's why I mentioned the TMP example, I was trying that yesterday but no success. My gut feeling is that this is about an access (write) violation, as it works on a Windows machine without all of the usual restrictions on C:/Windows directories. I think setting the writeable TMP path is part of it, but I need to do more testing. Ideas are welcomed.

[Astrid Emde (WhereGroup)]

Maybe we just write a comment in the httpd_mapbender.conf​ file that there has to be write access on the machine to the TEMP /TMP file.

Then the user has to take care about this.

Like this
# Please make sure that you have write access to the TEMP/TMP-directories.

[Jeff McKenna]

I meant: the TEMP/TMP writable directory for MS4W applications ( /ms4w/tmp/ms_tmp/) is not the solution to the Mapbender 3.2 problem. I can still trigger the errors when using the correct writable directory.

I believe it has to do with the other references to C:/Windows (WINROOT) etc, but more testing is needed to confirm. (I could be totally wrong)

Worst case, I will need to spend much effort running this through debuggers.

[Astrid Emde (WhereGroup)]

httpd_mapbender.conf version 2 with less env variables

[Astrid Emde (WhereGroup)]

I reduced the varibales in the httpd_mapbender.conf ( seeversion 2 with less env variables).

Mapbender is still slow but writes the tmp-files to /ms4w/tmp in the end. Maybe run F5 for the application if it is not there right away.

​http://localhost/mapbender/
​http://localhost/mapbender/app_dev.php/application/mapbender_user

/ms4w/tmp is also defined in the php.ini file

See also ​http://localhost/mapbender/app_dev.php/_profiler/phpinfo

[Jeff McKenna]

I also tried this (removed all mention of Windows paths)

Same errors.

(am aware of MS4W's tmp settings for PHP, as I created them)
(of course I am monitoring through browser's developer tools)

Will keep testing and likely have to spend a few days of effort running through debuggers to find what Mapbender 3.2 requires, where Mapbender 3.2 needs access, and its FCGI demands...

(if anything, we can see now that MS4W is relied upon heavily by organizations on their production servers, for Mapbender)

[Jeff McKenna]

There are many 500 errors (even after refreshing/F5), but one I frequently see is:

http://127.0.0.1/mapbender/app.php/application/mapbender_user/assets/trans

    500: Internal Server Error

[Jeff McKenna]

Will keep working on this.

If organizations can contact me to help fund all this effort, please do, as it seems very critical to so many organizations.

Thanks for the feedback!

[Astrid Emde (WhereGroup)]

Hi Jeff. Please gve me time to check. I will reach out to you tomorrow.

[Jeff McKenna]

I'm not sure what to say more now, other than it will take me time/effort to figure out what is causing these internal server errors, with Mapbender 3.x.

I'll keep this ticket updated with progress.

Thanks for those taking the time to test and provide feedback here.

[Jeff McKenna]

I spent much effort on this. The entire stack was rebuilt for Mapbender 3.2.x

Today's MS4W 4.0.5 release includes Mapbender 3.2.3 and PHP 7.4.13 etc. etc.

Thanks for the feedback here.
