New post creation fails in some browsers when it has a duplicate title

[Nao]

When you create a new post with a title that already exists in the past posts, the post creation fails.
After a while this error appears:

Fatal error: Maximum execution time of 30 seconds exceeded in /path_to_wp_install/wp-includes/wp-db.php on line 170

So far this has occured in these environments:

• Windows: Firefox 2.0.0.13 / IE 7.0.5
• Mac: Firefox 2.0.0.13 / Flock 1.1

I didn't have this problem with Safari 3.1 (Mac).

Works for me, this is not a browser related problem, otherwise you wouldn't have gotten the PHP timeout message. This seems to be a server environment error, your php, mysql, and http server versions would be more helpful.

My environment is:

• PHP 5.2.3
• MySQL 5.0.41
• Apache 2.0.59
• APC 3.0.14

There are at least two other sets of environment that reported the same issue (apache version unknown).

• MySQL 5.1.22-rc
• PHP 5.2.4
• Browser (all on Windows): Firefox2.0.0.13 / IE 7.0.5 / Safari 3.1

• PHP 4.4.4
• MySQL 4.0.25
• Browser: ?

We all were able to post a new duped-title entry after posting it with a completely different name, then changing to the intended title.

I thought this may be specific to Japanese text (all of the above use WP 2.5 + Japanese language file), but the same thing happens with roman-numeral titles.

I also found this post in the forum:

Let me know if there's any other information I can provide.

Fix for duplicate title post error

[Nao]

Upon further testing, this problem was replicated in these situations:

• The title includes multibyte character (new 2.5 install can take duped title if it's all alpha-numeral) OR
• WP is Upgraded from v.2.3.3 (duped alpha-numeral title also fails with this)

Mmtek, maybe you were testing w/ new install of WP 2.5? Could you test it again and see if you can see this happen.

If you want to test w/ multibyte title, please paste this: 日本語
or paste random text from any multibyte code site (Japanese/Korean/Chinese). thanks.

I've also attached a patch.

Looks like like it. Marking this one as a duplicate.
