- Received an account on linux 2 to install my own local installation of devmo wiki for testing.
- Problem: After checking out the wiki source from devmo, I used sancus's devmo configuration file to get this running, but it kept redirecting to his installation for some reason. Browsing the setting files, etc. didn't reveal any solution.
- Solution: sancus and shaver suggested using a hostname instead of a user directory link (ie. /~melz). Strangely, that fixed it. A mystery.

- Checked out devmo's css files (it was in a different path) and moved it so that everything loads up properly.
- Everything looks great so I'm getting my own dump of devmo's wiki contents instead of pointing to sancus's installation
- Problem: Had issues getting 'mysqlimport' to populate my database.
- Solution: Ended up using just 'mysql' and the errors stopped. 'mysqlimport' seems more picky for some reason.
- All set up and ready to go.
October 25, 2006
- Applied patch for bug #352411. Didn't work first time, no output from the search engine was displayed. Spoke to sancus about it and he managed to debug the issue so it's working now.
- New bugs to look at: 358112, 357682, 347924 or 353210/353208
- Discussed bug #357682 with sancus and got it narrowed down to a server configuration problem rather than on Nutch's side. (Update: sancus has closed this bug)
- Working on #358112 now...

Wrapping things up:
- Original test case works correctly again (output link - takes awhile to finish). My last modification while working on bug #358112 included a strange edit to the SpecialNutch_class.php file which redefined the $language variable (I have no idea how/when I added that line) causing the search engine to break - thus, my failure to demo the actual search engine working from the test site during the presentation. This really stumped me for awhile because I'm not supposed to edit that file in the first place.
- My fix for #358112 is here: SpecialNutch.php diff file. What it does: When you access the Nutch search form directly, it should only show a field for you to enter your search term. Since we are using English, the output automatically sets the language to 'en' (English) and no longer displays the drop down box (as seen on MDC currently).
- Thanks to Erin's help, I managed to write a basic test case to test my code. However, it only tests the 'en' language - (demo | code). The reason is because the code obtains the language from the URL that calls it ($_SERVER['PHP_SELF']). After reading up on a lot of documention, the only way to test other languages was create install the wiki for every language and test the URL string - which isn't feasible.
- Since there is no direct way that I can test every language, I decided to write a unit test that tests the code I used SpecialNutch.php. This tests constructs a URL for every language, eg. for Korean, the URL will be http://developer.mozilla.org/ko/docs/Special:Nutch. Then the code (being tested) will extra out 'ko' as the language and tests to make sure that is correct (demo | code).
- Wrote a short guide to getting started on this project, and avoiding the problems I had.
