AJAX viewer does not load map in Firefox 3 RC 1

[jng]

Using Firefox 3.0 beta 2 (Ubuntu Linux 7.10). Load any sample site at http://mapguide.osgeo.org/livegallery.html

The AJAX viewer will load without a problem, but the map itself will not load at all, and the zoom slider will be stuck at 0.0

[jng]

Still get the same problems with beta 3

[jng]

Using the following environment:

• Windows XP SP2
• MGOS 2.0.0 w/ Apache/PHP configuration w/ Shebpygan dataset
• Firefox 3 Beta 3

The following happens:

1. This POST operation fails

OPERATION=GETVISIBLEMAPEXTENT&VERSION=1.0.0&SESSION=1eef8b10-0000-1000-8001-000c292b5017_en_7F0000010AFC0AFB0AFA&MAPNAME=Sheboygan&SEQ=0.8608854176114282&SETDISPLAYDPI=96&SETDISPLAYWIDTH=824&SETDISPLAYHEIGHT=453&SETVIEWSCALE=98563.34333416916&SETVIEWCENTERX=-87.7302542509315&SETVIEWCENTERY=43.744459064634

2. That POST operation also kills/crashes the Apache service. Error logs show the following:

The Apache service named reported the following error:

Using mapguide 2.0.1, this crashed also my apache ticket:557

Both tiled and untiled maps in the basic viewer don't work in Firefox 3.0 RC 1. Firefox loads and then shows the following error in firebug

parent.InMeasure is not a function [Break on this error] if(!parent.InMeasure())

mapframe.php line 1115

I have seen any problem's with fusion layouts so far.

[tomfukushima]

Perhaps it is Sarrisa.js, can you try updating that to 0.9.9.4 and see if that resolves the problem? The file is in the viewerfiles directory of the web server extensions.

Also, can you try running Fiddler on the client and see which HTTP request is crashing Apache?

[zspitzer]

updating sarrissa.js made no difference..

using fiddler, there was no response to this request (#16)

which was done as a HTTP POST... POST ​http://localhost:8008/mapguide/mapagent/mapagent.fcgi

OPERATION=GETVISIBLEMAPEXTENT&VERSION=1.0.0&SESSION=c7c1dc7a-ffff-ffff-8000-005056c00001_en_7F0000010AFC0AFB0AFA&MAPNAME=Sheboygan&SEQ=0.3653077422034543&SETDISPLAYDPI=96&SETDISPLAYWIDTH=805&SETDISPLAYHEIGHT=570&SETVIEWSCALE=78331.92022873442&SETVIEWCENTERX=-87.7302542509315&SETVIEWCENTERY=43.744459064634

trying it as a HTTP GET doesn't crash...

[zspitzer]

ignore the ticket 16 link, i was just referring to the number of http requests logged whilst loading the viewer

[tomfukushima]

Would you be able to use Fiddler to see what the difference in requests is between FF2 and FF3? Thanks, Tom

[zspitzer]

Firefox 3 is sending a slightly different Content-Type

FF3: Content-Type: application/x-www-form-urlencoded; charset=UTF-8 FF2: Content-Type: application/x-www-form-urlencoded

apart from that the requests are pretty much the same, the post variables are slightly different ( but i think that's rounding stuff )

Interestingly, whilst FF2 will render the map, using live http headers replay function, the same request will crash apache when it's called by itself

While waiting mapguide team fix this, I suggest following workaround for time being. Add to WebServerExtensions/Apache2/conf/httpd.conf . At least works for me, YMMV

<Directory "C:/Program Files/MapGuideOpenSource2.0/WebServerExtensions/www/mapagent/">

<Files mapagent.fcgi>

SetEnvIf Content-Type "application/x-www-form-urlencoded" truef3 RequestHeader set Content-Type "application/x-www-form-urlencoded" env=truef3

</Files>

</Directory>

@tomfukushima

I'm not sure to have understood your words correctly. Do you mean that with your workaround you are able to view the map in the ajax viewer with Firefox 3?

[macieks]

i try this fix but still don't see map on FF3.

FF3 and firebug

FF3 and firebug

[gabrimonfa]

I think this bug is extremely important.

Firefox 3 is out, no possibility to download FF2 anymore. Firefox is by far the most used browser apart from IE. Not supporting Firefox3 cuts out a lot of users and destroys one of the major pros of this product, the fact that it is not available only for legacy, proprietary ActiveX enabled browser.

This bug was opened 6 month ago, and was here since the very first beta of FF3. In my opinion 6 month are enough to try to fix such an important bug!

[guest]

I was also able to get it working by applying the workaround suggested. Please make sure the following line is not commented out in your httpd.conf:

LoadModule headers_module modules/mod_headers.so

Hope it helps. Dário Oliveros

[tomfukushima]

OK, it looks like we're not getting much progress on this. I compiled the code and debugged and sure enough it looks like FF3 is sending the content type in the extended format that Zac mentions. And sure enough the code expects it in the FF2 format and that is causing the failures. Can you try using the attached files (FixedFiles.zip, MD5: 1339dedef68a59cc2646c4caa6ee0663) to see if it fixes your problems and doesn't introduce new ones?

This will only work for MGOS 2.0.1 on Windows. To do this: Stop your web server. Find occurrences of the file in your webserverextensions install and replace them with the attached (you should really also make copies of the originals in case you need to restore things). Restart your web server. Test.

If you test this please post a note in this ticket with the configuration you tested and the results.

I'll post a patch (called FF3Fix.path or something like that) for those who are compiling from source.

Thanks, Tom.

[zspitzer]

The patch files worked successfully for me :)

Using MG 2.0.1 & XP SP3 FF 3.0 & Apache

[zspitzer]

I tried applying the patch on Linux against the 2.0.x branch.

The basic viewer now works on linux as well, but fusion isn't working for against my linux server with Firefox now. It does, however, work with IE.

It just seems to hang silently.. digging with fiddler I saw an error which looks like an ELF binary (mapguide.fcgi ?) is being passed by fusion as the sessionid

[zspitzer]

Must of been some weekend gremlins at play, I just tested this again and it's all now working fine with Fusion and the Basic Viewer with FF3

[tomfukushima]

Thanks Zac for the update. I was in the process of building on Linux (and having problems) but I'll put that on the back burner now. Tom

[sledhead45]

Has anyone found where to apply these fixes for 1.2.x? I dont mind upgrading to 2.0 to simply use the provided patches, but following these instructions ​http://trac.osgeo.org/mapguide/wiki/1.2to2.0MigrationInstructions my RestoreRepositories.sh fails on step 4. Thanks. --travis

[gingerbbm]

I'm using MapGuide Enterprise 2009 on IIS and Firefox 3 isn't working. I'm afraid I don't know how different the commercial product and the open source product is. Should I expect the files provided in FixedFiles.zip to work for me?

Thanks, Stuart

[tomfukushima]

Hi Stuart, I briefly tried dropping these DLLs into some other configurations but they only seemed to work on MGOS 2.0.1. For other versions of MG, perhaps the fix posted on the MapGuide Users mailing list to change some of the POST requests into GET requests will work. Tom

[gingerbbm]

Thanks Tom, I since found the POST/GET discussions and will try it out.

[amathos]

The patch don't work. My configuration is: Windows 2k3 Sp2,Firefox 3.0.1,IIS 6,Map Guide Open Source 2.0.1

[tomfukushima]

Can anyone else confirm or deny amathos' problem? Thanks, Tom

[sledhead45]

I'd like to help, but how would I go about checking my version installed? I installed according to ​This Guide from early july 08, and mapguide looks good in firefox3 for me. My demo is running ​here.
--travis

[sledhead45]

woops, the working link is ​here .

[amathos]

I tryed with files in FixedFiles.zip, but unfortunately isn't work :( Is possible an incompatibility with IIS?

Tanks.

[amathos]

Ok, the problem is outdated with new version of Mozilla Firefox (3.0.2)

[zspitzer]

This fix is included in mapguide 2.0.2
