New subject: Strange behaviour: HTML output window - loading non-existing css leads to a timeout

26 Jan 2015

Hi,

I bumped into a problem while checking the R bundle.

There's a command which outputs HTML source to display the result within TM's HTML
output window.

If I start TM and execute this command everything will be displayed correctly. Then I
close the HTML window, I modify some code, and invoke the same command again to come up
with an HTML output window I only see the spinning wheel and a blank window. After ~30s
the HTML window displays the correct picture.

I was able to narrow down the problem and attached is a test environment (as a tmCommand).
The problem is a non-existing CSS resource. If you invoke this command for the very first
time, the HTML output window machinery simply ignores the non-existing CSS file and
displays the content correctly. Fine. If you re-invoke the same command the HTML output
keeps blank for half a minute. If you then delete the 4th "echo"-line containing
R.css everything works perfectly.

Here the test code

#!/usr/bin/env bash
[[ -f "${TM_SUPPORT_PATH}/lib/bash_init.sh" ]] && .
"${TM_SUPPORT_PATH}/lib/bash_init.sh"

echo "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01
Transitional//EN\">"
echo "<html><head><title>R: Phonetic
algorithms</title>"
echo "<meta http-equiv=\"Content-Type\" content=\"text/html;
charset=utf-8\">"
echo "<link rel=\"stylesheet\" type=\"text/css\"
href=\"R.css\">"
echo "</head><body>"
echo "TEST"
echo "</body><html>"
