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>"
