0001727: Wordpress blog view fails after install

Notes
(0001897) urubatan 05-07-07 12:42	I found the bug that causes this, it is a bug in the StringModule, more exactly in the class com.caucho.quercus.lib.string.StringModule.PrintfSegment. the two methods that parse formated strings had little problems, I have changed both and now I have wordpress 2.1 running OK on quercus. I do not know how to send a patch, since we do not have CVS access to the sources, so the fix is here: remove the break in the method getIndex, it will look like this: static int getIndex(String format) { int value = 0; for (int i = 0; i <format.length(); i++) { char ch; if ('0' <= (ch = format.charAt(i)) && ch <= '9') value = 10 * value + ch - '0'; } return value - 1; } the original version had a problem parsing strings in the format: " %2$d" change the expression parsing in the getIndexFormat method, that has a problem parsing the format above too. static String getIndexFormat(String format) { //int p = format.indexOf('$'); return format.replaceAll("[0-9]*\\$", ""); } after this corrections, I found an exception while listing the history of the blog, and found it to be caused by an unimplemented cmpObject method in the class com.caucho.quercus.env.ObjectValue, I have changed the method to return "0" instead of throwing an exception (it looks like this now) public int cmpObject(ObjectValue rValue) { return 0; //throw new Run timeException("not implemented"); } and now I have the wordpress 2.1 fully functional with Tomcat 6 and Quercus. I hope Caucho people can use this "patch" for the next version of Quercus, and if is there a way to get access to the CVS or SVN I can send a .patch file next time. Thanks for the great software.

(0001914) nam 05-15-07 09:20	I think objects comparison is not yet implemented. But I have analyzed the function have_posts() and it never compares objects. It is a quercus bug if it did. Therefore, I am reluctant to fix the "not implemented" exception because it would just mask the underlying problem. urubatan, are you seeing the issue from a fresh install? What are the exact steps to reproduce it because I have been unable to reproduce this issue.
