Missing miva pages

Well, its not miva that is giving you a page/script not found error...its the web server.
Typicially this is defined by the web server's main config script. You could define it as
not_found.mv and run Miva script inside that file...

No Bruce - I already know how to run a mivascript for a standard 404 error
from the webserver.
But this is not the case I am talking about. If you request an url for
foo.mv and foo.mv does not exist, Miva generates a one line syntax error:
Unable to open path/foo.mv
Of course it also does the same thing if you make an MvDO call to a
nonexistant script in the middle of a script.
It is indeed curious that the server doesn't check the existence of the
URL before handing it to Empresa (or Miva Mia where the same thing
happens) but it has happened to me on every server where I've used Miva
for the past 6 years.
It prevents a graceful death.
Since my initial post, I've been right through the Empresa config
documentation, but I can't see anything which would help.

Missing miva pages

Just put in some basic error checking routine to the calling script. It
the missing URL is called by a browser, they will get a 404 error. If it
is MvCALLed you need to trap it with an error check routine. Like (typed
freehand, might need fix):

<MvCALL this sucker>
<MvIF EXPR="{ MvCALL_Error }">
<MvASSIGN NAME="g.Error_Message" VALUE="{ MvCALL_Error }">
<MvEVAL EXPR="{ g.Error_Message }">

<MvEXIT>
</MvIF>

But I'm not talking about MvCALL, I'm talking about any link typed into
the browser or a link on any web page (not necessarily on your site). Can
you confirm that if you follow
<A HREF ="http://www.firework.co.nz/fireworks/stage_pyro_cannon.mv you don't get a ">http://www.firework.co.nz/fireworks/...pyro_cannon.mv you don't get a </A>
404 page, only the error message from miva?

Checking the existence of every link before writing the link would be a
huge performance hit on a site. (That's why Wikipedia is so slow!)

Missing miva pages

The sample you offer is not giving a 404 error. But it is because of
server config, nothing to do with Miva Script.

Look closely at your Apache error page definitions for the site, or what
might be there munging the results.

The link you offered generates a 200 result instead of the 404 it should.

Missing miva pages

Well, first it's not the web servers responsibility to know
if the file exists or not. All it knows is that whatever is
that the file requested ends in .mv (or .mvc) and it should
turn over processing to something configured in it's .conf
file.

That being said, you need to put in some error checking.

If someone is typing in the missing file to the URL bar, or
a remote file calling you, then you have to have a backup
plan with 404 processing.
If it's a script you're running and MvGOing a local file,
use sexists().
If it's a script you're running and MvCALLing a remote
file, then check for MvCALL_ERROR.

Hmm, this gets more interesting. After a discussion with my hosts I tried
a whole lot of nonexistant urls on miva powered sites

HOST SERVER RESULT CODE OUTPUT
miva.com Apache/2.0.40 (Red Hat Linux) 404 error page
driftwood.net Microsoft-IIS/5.0 404 miva's
error message
paen.net Apache/2.0.50 (Fedora) 404 error page
[1]
firework.co.nz Apache 200 miva's
error message [2]
amnet.com Apache/1.3.6 (Unix) 404 error page
+ 404 for error document
truxoft.com Server: Apache/1.3.27 (Unix) 200 miva's
error message
phosphormedia.com Apache/1.3.31 (Unix) 200 miva's
error message
gilliganonline.com Apache/1.3.27 (Red-Hat/Linux) 200 miva's
error message
scotsscripts.com Apache/2.0.46 (Red Hat) 404 error page
mvcentral.com Apache/1.3.27 (Red-Hat/Linux) 200 miva's
error message

[1] A recent server from my host, running Ensim management
[2] A legacy server from my host, running plusmail management

Conclusion: It's starting to look like a bug in Apache prior to 1.3.6 - it
would be rather a coincidence if miva was returning different codes to
apache on precisely that mix of servers.

It matters to me because my CMS uses "real" urls (page calls cms script
which then includes page) and I need missing pages to die a lot more
gracefully. Looks like time to convince the client to upgrade servers.
