murderous net access during XML validation [message #140299]

I'm currently using a dialup connection, and going through the painful
process of converting an existing project to a WTP project. What's
making it most painful is that, apparently, as I move XML resources
around, in some cases I'm changing the filesystem/workspace locations of
schemas and DTDs. This means, I'm guessing, that when validation
starts, since it cannot find my local schemas and DTDs, there are
attempts to retrieve the schemas and DTDs from the namespace URIs and/or
the specified schema locations. But those of you who remember the DDD
(Dark Days of Dialup) will know what that means for me. It can easily
happen that, after one false move, I'm forced to wait ten minutes
watching "workspace rebuilding" while this process plays out.

What would make this a lot better, from my point of view:

1. Display some useful information about what's going on in the
"details" view of the progress dialog. For instance, tell me that
you're trying to retrieve the schema from whatever URL, tell me that you
did or didn't get it, show me download progress, etc.

2. Offer me the ability to prohibit network access for getting schemas
or DTDs, like the "--nonet" option on xmllint. (Or is this available
somewhere in a preferences tab?)

Most of all, and I'd call this a bug:

3. Allow me to cancel this process! (I mean "Validation of <project
name> by XML Validator") I simply cannot kill it from inside Eclipse.
I have to forcibly kill Eclipse ("killall eclipse") to escape. Hitting
the little red "stop" box doesn't do it. It greys out, but the
"building workspace" thing still seems to go on forever, and I'm
prevented from doing even basic things like moving or deleting files.

But listen, thanks for this project -- what a fantastic and ambitious
collection of tools!

Thanks,
Noel

This does sound painful and I've heard other reports. There was a bug in
0.7 that caused the XML validator not to use the DTD and schema files in
the cache. The fix that allows the XML validator to use the cache should
make things easier for you.

Hmm. I think easier said then done but open a defect and I'll investigate
into this.

Another interesting one. This is an enhancement and will probably be
difficult to implement consistenly in the tooling but please open an
enhancement request (a bug with priority set to enhancement).

Absolutely! It would be really good to get this into M9 and some of the
fixes in the validation framework should make this easier to accomplish. I
don't think there is an open bug for this so please open another one for
this.

You're welcome. Thanks for the feedback!
