Problems upgrading to 4.6.1 or 4.8.0-beta2 from 3.6.6 (Not about the foundation :)

[Doyon, Jean-Francois]

Hello,

So we've bitten the bullet and started the process to upgrade from 3.6.6 to
4.6.1 (And possibly 4.8).

Mostly, things came across as expected, knowing what has changed and so on.

Problem 1: REQUIRES.

I'm aware of the bug in 4.6.1, so I'd backported the fix into it, and things
were working ok for little while.

Now however, it just won't work :(

I've tried my version of 4.6.1 AND a "stock" 4.8.0-beta2, without success.

Here's an example:

Layer 1:

        LAYER
                NAME vegetation_250K_legend_zoom_3_4
                STATUS OFF
                GROUP base
                TYPE POINT
                MINSCALE 42001
                MAXSCALE 300001
                METADATA
                        "nolaydesclink" "2"
                        "lay_title"    "Vegetation"
                        "checkable"    "2"
                        "legend_order"    "40"
                END
                CLASS
                        NAME "Cut Line: Firebreak"
                        SYMBOL cutline_firebreak_alt
                        SIZE 20
                END
                CLASS
                        NAME "Cut Line: Other"
                        SYMBOL cutline_other_alt
                        SIZE 20
                END
                CLASS
                        NAME "Wooded Area"
                        SYMBOL wooded_alt
                        SIZE 20
                END
        END

Layer 2:

        LAYER
                NAME vegetation_polygon_250K_map_zoom_3
                STATUS DEFAULT
                GROUP base
                TYPE RASTER
                MINSCALE 80001
                MAXSCALE 300001
                REQUIRES "[vegetation_250K_legend_zoom_3_4]"
                METADATA
                        "legend_order"    "-2"
                        "wms_srs"             "EPSG:42304"
                        "wms_name"
"VEGETATION_2:BNDT_250K/NTDB_250K"
                        "wms_server_version"  "1.1.0"
                        "wms_formatlist"
"image/gif,image/png,image/jpeg,image/wbmp"
                        "wms_format"          "image/gif"
                END
                CONNECTIONTYPE WMS
                CONNECTION "http://mydomain.com"
        END

Unfortunately, turning on layer 1 does not make layer 2 appear, even though
it's "DEFAULT" ... The only way this works is if we comment out the REQUIRES
in Layer 2 ... Then it'll appear.

I have no idea what happened to either make my custom 4.6.1, or even worst,
the 4.8 beta, NOT work :(

I upgraded libcurl to 7.15.0 ... Could that be a problem? I also use
gdal/ogr 1.3.0 and gd 2.0.28 ...

Problem 2:

Pixmap symbols don't appear in the legend (An HTML legend).  The symbols are
just white or transparent gif's (Of the right size, 20x20 in this case).
Vector symbology still works fine, other symbols are gif files, these are
the problematic ones.

Problem 3:

Intermittent "no index item defined" errors.  I have to try and track this
down further ... But if anyone has already run into this?
I saw a few discussions on the topic, but nothing that seemed relevant in my
case.

One problem we had where mapserver would die without an error message (well,
an empty one) was solved by re-generating the data (shapefiles) ... Are
these versions of mapserver more data sensitive somehow?

Thanks in advance for any help! I'm dying here :P
