Hi Guys,
While away on training last week, we came across the Windows debug
build reporting problem in std::sort and find calls, and
investigations into the issue suggested that it was down to the cull

those same fields were being u
Hi James,
I tried to look to this problem but can't find anything, moreover it seems
to work without problems in release (I'll try to make some stress tests soon
to be sure).

I'm having a similar issue with DatabasePager::RequestQueue::takeFirst()
(osg trunk, Debug build, windows XP VS2005). I'm getting some assertion
errors at _requestList.sort ("sequence not ordered"). Even after adding
the updateBlock().

Hi Csaba,
Thanks for spotting the missing updateBlock(). I've now added this
and checked it in. I put the updateBlock() inside the if () {} code
block, but other than that is identical to your own change.
Must admit I hadn't spotted the problem, the downside of having a four
core machine...

Hi Robert,
Have you already updated the pager with these changes ?
I was looking to the debug crash, but I'll wait for these modifications to
see if it changes something.

Hi Pagees,
I've been looking into the problem of memory growth in the new rev of
the DatabasePager and I've tracked the problem down to the new
mechanism of attached DatabaseRequest's via a ref_ptr<> to
PagedLOD/ProxyNode nodes. The DatabaseRequest themselves had a
ref_ptr<> which creates a circu

Hi All,
Looking at the enthusiasm all around new improved DatabasePager I would
also like to try my hands on it by reading data from http, but have not
much idea about how to do that. Will my node look like this for using

Hi Robert,
Yes, I also wish there was an easy wrapper around OpenThreads to help one
debug the multi-threaded execution.
What do you have in mind w.r.t an "easy wrapper around OpenThreads"?

and OpenGL and can trace all c

Hi Serge,
I test the new DatabasePager with a regular pagedLOD database.
Like you : all seems to work fine in release mode but I have a crash in
debug mode.
I work with Visual studio 2005 under Windows 2000.

Hi Serge,
Curious. The particular bit of code does actually acquire the mutex
lock - the whole method is:
void DatabasePager::RequestQueue::takeFirst(osg::ref_ptr&
databaseRequest)
{
OpenThreads::ScopedLock lock(_requestMutex);
if (!_requestList.empty())
{
_requestList.sort(
Forget what I've said, I found a workaround.
My custom PagedLOD works juste fine with the new DatabasePager, but only
in release mode.
In debug, Visual Studio spot an error in :
DatabasePager.cpp line 272 :
if (!_requestList.empty())
{
_requestList.sort(SortFileRequestFunctor());

I now wonder if the PerRangeData shouldn't be a base class that you

Hi Robert,
All these things are good news ! :)
I am currently building and I'll let you know how it works here (I have a

Hi All,
Over the last week I've been working on improving the performance of
the DatabasePager when paging data over http, and storing the tiles in
a local file cache, I checked in the first cut of the work last night.
Previous rev of the DatabasePager had only a single thread for
reading tiles,
35 matches
