<div dir="ltr">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:<div><br></div><div> MS_MAP_PATTERN "^\/etc\/mapserver"</div><div><br></div><div>You need to be running the latest version for this to work as intended and of course that's strongly recommended.</div><div><br></div><div>--Steve</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jun 3, 2021 at 8:12 AM Jeff McKenna via mapserver-users <<a href="mailto:mapserver-users@lists.osgeo.org">mapserver-users@lists.osgeo.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi David,<br>
<br>
MS4W also uses PCRE for its regex engine, so Windows users will soon be <br>
facing these same issues as you (I'll be making this as easy as possible <br>
for the new Windows users).<br>
<br>
So to answer your question: I believe most users aren't yet aware of <br>
what regex engine they use, and, also I believe that the PCRE regex <br>
engine is used more frequently in the MapServer community than what is <br>
believed. (most automated tests do not use PCRE, for example, even <br>
though it is so commonly used)<br>
<br>
I'm not sure if I have the answer that you need, but I wanted to give a <br>
perspective from the Windows side.<br>
