> Performance in ImageHtmlEmail
> -----------------------------
>
> Key: EMAIL-198
> URL: https://issues.apache.org/jira/browse/EMAIL-198
> Project: Commons Email
> Issue Type: Improvement
> Affects Versions: 1.5
> Reporter: Jochen Wiedmann
> Assignee: Jochen Wiedmann
> Priority: Minor
> Fix For: 1.6.0
>
>
> In the class ImageHtmlEmail, there are two regular expressions
> (REGEX_SCRIPT_SRC, and
> REGEX_IMAGE_SRC), which can behave rather slow in exceptional cases, as
> evidenced by
> the following code snippet:
>
> @Test
> public void testSlowRegularExpressions() throws Exception {
> ImageHtmlEmail mail = new ImageHtmlEmail();
> mail.setHostName("example.com");
> mail.setFrom("[email protected]");
> mail.addTo("[email protected]");
> StringBuilder text = new StringBuilder("<img");
> for (int i = 0; i < 3000; i++) {
> text.append(" ");
> }
> mail.setMsg("<html><body><pre>" + text + "</pre></body></html>");
> long startTime = System.currentTimeMillis();
> mail.buildMimeMessage();
> long duration = System.currentTimeMillis() - startTime;
> assertTrue("Run time exceeds permitted duration of 50 seconds: " +
> duration,
> duration < 100*1000);
> }
