Hibernate Query Result view gets dramatically slow when query text has '\t' characters -------------------------------------------------------------------------------------- Key: JBIDE-11372 URL: https://issues.jboss.org/browse/JBIDE-11372 Project: Tools (JBoss Tools) Issue Type: Bug Components: hibernate Affects Versions: 3.3.0.Beta1 Reporter: Viacheslav Kabanovich Assignee: Dmitry Geraskov Fix For: 3.3.0.Beta3 EXECUTE: Open HQL Editor, and type some long query using tabs (\t) instead of usual whitespaces. EXECUTE: Send the query into Hibernate Query Result view. ASSERT: New tab folder is added to the view in 1-2 seconds even for queries as long as 1000 characters. ASSERT: Resize of the view goes without delays. FAILURE: For a query of 120 characters, including 15 \t characters, creation of new tab folder, and each subsequent resize of the view takes 7 seconds. Doubling text size increases time 8 times. SWT methods CTabFolderRenderer.shortenText(GC, String, int, String), TextLayout.getPreviousOffset(int,int), GC.textExtent(String,int) have poor performance for long strings with \t characters. I have created issue https://bugs.eclipse.org/bugs/show_bug.cgi?id=374987 Class HQLQueryPage sets tab name as {code} setTabName(getQueryString().replace('\n', ' ').replace('\r', ' ')); {code} This issue may be solved by modifying it as {code} setTabName(getQueryString().replace('\n', ' ').replace('\r', ' ').replace('\t', ' ')); {code}
