Re: [MapServer-users] Mapfile -> EMPTY-Parameter -> Migrate from MS 7.6 -> 8.0

[Steve Lime via MapServer-users]

Hi Georg: There was a regression in 8.0 that broke the EMPTY redirection.
It had to do with considering 0 results as a valid query result and not an
error. The functionality was fixed in 8.2 and is working fine for me at
least.

Re: [MapServer-users] OGC API Features Part4 CRUD

AFAIK nothing is planned. I think that’s probably a much more significant
effort relative to the initial implementation. —Steve

Re: [MapServer-users] Runtime substitution on MAP CONFIG environmental variables

[Steve Lime via MapServer-users]

The validation block would go in the WEB object. However, the runtime subs
don't operate with config options. There was a ticket related to this
message opened already (see
https://github.com/MapServer/MapServer/issues/6994), presumably based on
this thread. I'm curious what other devs think about the idea.

I do this all the time to create static versions of assets. Typically I

curl wouldn't work just fine. What does a curl call look like?

It won’t work. A configuration is loaded in entirety first, and then

Re: [MapServer-users] multiple shapepaths

[Steve Lime via MapServer-users]

One other thought, you can use multiple paths via runtime subs to
approximate what I think you’re looking for, so:

WEB
  VALIDATION
path1_default “/opt/path1”
path1 “^\/opt\/path1$”
path2_default “/opt/path2”
path2 “^\/opt\/path2$”
  END
END

Then in DATA values you’d use %path1% or %path2%. This is another use case
for variables that was suggested recently. We could, perhaps, define a way
to mark something as immutable via url so the regex could be simplified and
only the default would ever be used (e.g. “path2” “immutable”).

Hi Astrid: I noticed this too but in a slightly different way. It's a bug,
see the discussion here:

Basically the EMPTY keyword is being ignored. This will be fixed in 8.2...

Re: [mapserver-users] CGI variable "map" fails to validate.

[Steve Lime via mapserver-users]

I should note that 7.6.3 (also 7.4.5, 7.2.3 and 7.0.8) should make defining
a value for MS_MAP_PATTERN much simpler. We updated things to use two
filters instead of one. The first, MS_MAP_BAD_PATTERN, checks for
problematic character sequences in the map value, for example /./, /../ or
// and fails if there is a match. This means you don't have to account for
those with MS_MAP_PATTERN alone and you can just write something simple
like:

  MS_MAP_PATTERN "^\/etc\/mapserver"

You need to be running the latest version for this to work as intended and
of course that's strongly recommended.

Re: [mapserver-users] CGI variable "map" fails to validate.

[Steve Lime via mapserver-users]

Hi David: Presumably the Docker image is running the most recent version of
7.4 which would have that pull request applied. That said, I don't think
it's the culprit here and I have seen some issues with -'s where the
MS_MAP_PATTERN expression compiles fine but doesn't match as expected.
Re-writing the expression to move the - character can help. Try this:


MS_MAP_PATTERN=^\/etc\/mapserver\/([^\.][-_A-Za-z0-9\.]+\/{1})*([-_A-Za-z0-9\.]+\.map)$
