Description

It seems that WStreamResource does not work correctly under wthttpd. I have attached simplified version of my WStreamResource class.

Hope you will compile it and test it.

Hey,

There was indeed a regression in resource continuations.

This is fixed in git.

The following patch will also fix this:

diff --git a/src/Wt/WResource.C b/src/Wt/WResource.C
index 23ec176..04f0e49 100644
--- a/src/Wt/WResource.C
+++ b/src/Wt/WResource.C
@@ -128,6 +128,9 @@ void WResource::handle(WebRequest *webRequest, WebResponse *
   Http::Request request(*webRequest, continuation);
   Http::Response response(this, webResponse, continuation);

+  if (!continuation)
+    response.setStatus(200);
+
   handleRequest(request, response);

   if (!response.continuation_ || !response.continuation_->resource_) {

By the way, as you will notice, the HTML renderer implementation does not (yet) attempt to be efficient when laying out tables (or even in general): each time a column needs to be widened because of cell contents, it will cause the whole table to be re-layout. If you can't live with that, his should either be fixed, or you can work around it by imposing the column widths in the first row.

Regards,

Thanks again twice: for patch and suggestion...

I will have fixed widths in the first row.

How can i impose the column widths in the first row ? Can you provide working example (which is faster) ? I tried some solutions but failed (still need loong time to produce PDF).

Hey,

That was the theory indeed, in practice it turned out that widths were ignored.

Here is a patch that fixes that (also in git).

With this patch, css widths set on a table cells (td or th) will be taken into account.

e.g.

...

diff --git a/src/Wt/Render/Block.C b/src/Wt/Render/Block.C
index ddd2129..18575ea 100644
--- a/src/Wt/Render/Block.C

       switch (hAlign) {

        break;
