Important notes when upgrading to MS4W 5 from MS4W 4
REQUIREMENTS.txt
- always first follow the instructions in the file /ms4w/REQUIREMENTS.txt to install the updated "Microsoft Visual C++ Redistributable" on your server
ms4w.conf
- as of MS4W 5, you must configure the new /ms4w/ms4w.conf file, as the MapServer 8.0 release tightened security for the MAP= parameter
- see https://ms4w.com/README_INSTALL_MS4W_5.html#securing-your-ms4w-installation
SWIG MapScript
PHP
- test PHP MapScript at the commandline by executing:
setenv.bat php -dextension=C:/ms4w/Apache/php/ext/php_mapscript.dll -r "echo msGetVersion();"
- as of MS4W 5.0, there is no external file to include in your PHP scripts (the constants and functions are wrapped inside the MapScript PHP extension instead)
- see the updated example scripts here on the Wiki, such as:
- quickmap.php has also been updated (see locally at /ms4w/Apache/htdocs/quickmap.php)
- be aware that with the MapServer 8 release, many deprecated things have been removed and will now throw an error. For example, there is no longer a setMetaData() function for a Layer (or a getMetaData() function), in SWIG MapScript. Instead we must access the 'metadata' hashTableObj keys and values directly, here is a working example:
<?php //set metadata using the new 'metadata' hashTableObj keys and value directly $oWMSLayer->metadata->set("wms_name", "popplace"); $oWMSLayer->metadata->set("wms_title", "Cities"); $oWMSLayer->metadata->set("wms_srs", "EPSG:3978"); $oWMSLayer->metadata->set("wms_server_version", "1.1.1"); $oWMSLayer->metadata->set("wms_format", "image/png"); //set the PROCESSING directive on the layer (not beneficial for WMS layers, but useful for database layers, so set here only as an example) $oDBLayer->setProcessingKey("CLOSE_CONNECTION", "DEFER"); //get LAYER metadata using the new 'metadata' hashTableObj keys directly echo $oWMSLayer->metadata->get("wms_title"); //get WEB object metadata echo $oMap->web->metadata->get("wms_title"); ?>
Python
- test Python MapScript at the commandline by executing:
setenv.bat python -c "import mapscript; print (mapscript.msGetVersion())"
- quickmap.py has been included in /ms4w/msplugins/mapscript/python/ (follow the instructions at top of file)
- the GDAL Python utilities can be called at the commandline such as:
setenv.bat gdal_merge --help gdal2tiles --help
- test the GDAL Python module at the commandline by executing:
setenv.bat python -c "from osgeo import gdal;print(gdal.__version__)"
- upgrade pip
setenv.bat python -m pip install --upgrade pip
PROJ
- Apache's conf & setenv.bat now set the environment variable PROJ_DATA to PROJ's new location:
\ms4w\share\proj
If your mapfiles set a PROJ_DATA (which is not recommended, as MS4W's Apache does this for you) you will have to update your PROJ_DATA value - MS4W 5.0 includes PROJ 9, which (since PROJ 8) contains many changes:
- since the PROJ 9.1 release, for the former PROJ_LIB variable has been replaced with PROJ_DATA
- allowing to dynamically pull in various grids, to improve accuracy
- see settings in /ms4w/share/proj/proj.ini
- since we are involved in displaying maps over the internet, we should likely have these grids locally on the server
- execute the following to install the grids (into /ms4w/share/proj/)
setenv.bat proj-install-grids.bat
- execute the following to install the grids (into /ms4w/share/proj/)
- all EPSG codes are stored in proj.db, an SQLite database, stored in /ms4w/share/proj/, instead of the former epsg text file
Removed Mapfile Parameters
The following (formerly deprecated) popular mapfile parameters will now cause errors in your MS4W 5.x mapfile, so you MUST REMOVE them:
- DUMP TRUE
Instead, you can configure querying of your layer by using METADATA instead, such as:
LAYER ... METADATA "wms_title" "Populated Places" "wms_include_items" "all" "gml_include_items" "all" "gml_featureid" "ogc_fid" END #metadata ... END #layer
- OPACITY at the LAYER-level
Instead it must be inside a COMPOSITE object:
LAYER ... COMPOSITE OPACITY 40 END #composite END #layer
- COLOR at the CLASS-level
Instead it must be inside the class' STYLE object:
LAYER ... CLASS ... STYLE COLOR 120 120 120 END #style END #class END #layer
see the full list of removed parameters
map2img
The former shp2img commandline utility has been renamed to map2img.
