'''Changes do not appear in article 2002/05/10'''

I made substantial changes to the article for [[Earth]] and though they appear in the most recent diffs, they do not appear in the article. It doesn't look like normal counter-editing (which would show in the diffs, right?). I tried deleting my browser's history files, and there was still no effect.

:Known cache problems. Edit and resave the page to clear the old cached version, or wait until Jimbo clears all the old cached pages. [[user:Brion VIBBER|Brion VIBBER]], Saturday, May 11, 2002

'''+ or _'''<br>

The &action=history for http://www.wikipedia.com/wiki/adrenal+gland refers to a number of http://www.wikipedia.com/wiki/Adrenal_gland pages. Are these pages the same?

:Yes, those are the same. The "+" is just a URL-encoding for a space, which is canonically changed to "_" for the internal database. The first letter is always capitalized internally so that a link at the beginning of a sentence and in the middle will not go to different pages.

'''Diff colors'''

Line 14 ⟶ 23:

'''Zero disappearing from diffs'''

The numeral "0" doesn't show up in the text of a diff when it comes immediately after a bracketing delimiter ("(", "[", "{"). See the history of [[unit interval]] for examples of each of these. In the HTML source of the diff file, the "0" simply isn't there. The problem doesn't happen with other numerals. -- [[userUser:Toby Bartels|Toby Bartels]] (2002/04/17)

:There's a fun "feature" in PHP whereby the string "0" is sometimes considered to be equal to the empty string "" because, as far as I can tell, a numerical comparison is being used. This sounds suspiciously like an instance of that problem; I'll look into it... [[user:Brion VIBBER|Brion VIBBER]], Wednesday, April 17, 2002

Line 20 ⟶ 29:

Here's another bug that I suspect is related. A less than symbol ("&lt;") that's the beginning of an HTML tag will sometimes be displayed in the diff as "&amp;lt;" instead of "&lt;". This again occurs after a bracketing delimiter. As for &gt;, an analogous effect occurs ''before'' a bracketing delimiter. For an example of this, see the diff for my edit today of [[ring ideal]]. -- [[user:Toby Bartels|Toby Bartels]] again (2002/05/05)

PS: I did a little experimenting -- see the history of [[user:Toby Bartels/sandbox]] -- and found it amazingly difficult to reproduce the effect. I could reproduce it with "0" only when the "0" was in red, and couldn't manage to reproduce it with "&lt;" and "&gt;" at all under a general condition. Take a look, if this might help.

'''Diff crashes on [[Separation_axioms]]'''

The latest (08:29 today) diff on this page returns the result:

:'''Line 188''':

:'''Fatal error''':

:Maximum execution

:time of 30 seconds

:exceeded in '''/home/wiki-'''

:'''newest/work-'''

:'''http/difflib.php''' on

:line '''267'''

:&nbsp;&lt;table border="1"&gt;

This seems to be coming from the PHP script.

Other diffs from earlier histories of that page are OK.

Update:

I've just made an edit to the article.

The diff for my new edit shows up fine, but the 08:29 diff still fails.

(The only difference is that it's now line '''258''' instead of line '''267'''.)

'''History of vote pages misses many edits'''

I suppose that the intended behaviour was not to mark in the history automatic votes, only hand edits.

Fair enough; only hand edits have useful commentary in the Summary.

Unfortunately, what actually happens is that the history records only the edits immediately ''before'' the hand edits.

If the hand edit is followed by an automatic vote, then it doesn't show up in the history; an automatic vote followed by a hand edit does.

Especially when the Summary of a hand edit explains why something was removed from a list, this is problematic.
