Hello BBO :
About several months ago,occasionally I found there are some wrong results on the Click Rate .
For example:
After I post a new topic just now, I know there are 9 plus spectators who are looking on my post, and then I have a reply at once in this thread.However,a strange thing happened,when I visited my topics again on the second day, topic list showed me only One People who had visited my topic,so I know this count of click rate must be wrong.so I wonder what had happened?

The number of views display for a topic isn't updated every time someone views the topic. So, the counter is right, but the text doesn't always reflect the value of the counter.

update?How many time do it update for once ? now I have to tell you I had ever seen 20 spectators in my eyes,and after 24 hours,the numbers of views display are less than 20!

Do you not believe what I said? I have observed this kind of counter for two months at least,but I don't know its wrong reasons.

Which thread are you talking about?

[barmar]

It's supposed to update the view count every 3 hours. There's a configuration option to update it immediately, but we have it turned off for performance reasons.

But I think you're saying that it's not updated long after 3 hours.

Dear barmar:

Most of the threads posted on Chinese Forum and China Entertainment World Forum ,its counts of views display are very wrong,I had ever seen 20 spectators in my eyes,and after 24 hours,the numbers of views display are more less than 20! this results are nothing with updated time in reality.there are something wrongs with your BBO counter of Click Rate.

It's not a BBO counter, it's part of IP.Board from Invision Power Services.

In Chinese Forum I see:

I only see one thread with less than 20 views:

复习超级转移叫 11 Views

This thread just started today.

Are you seeing different numbers of views for these threads?

[lycier]

For new posts,it is not so one thing.I found the view counts are wrong on the second day.

The thread with 11 views yesterday has 38 views today.

I'm pretty sure this is working correctly. The view counter for a thread is updated any time someone makes a reply to the thread, and every 3 hours for all threads. I just performed a couple of tests of both.

Test 1: I went to the Chinese Forum and added a reply to the thread with 38 views. The view count jumped immediately to 44. (I've deleted the reply.)

Test 2: I looked at a thread in this forum. I manually ran the "Update Topic Views" task (this is the same task that is normally run automatically every 3 hours). The thread's view count increased by 1.

I looked at how this all works. There's a small chance for occasional views not to be counted. When someone views a thread, an entry is added to a "topic_views" table in the database. The "Update Topic Views" task works by counting the number of entries for each thread, and adding this to the view count of the threads. After it does this, it clears out the topic views table. Any views that take place between those two steps will be lost. But the task only takes a few seconds (and has a limit of 30 seconds), so this should not be a big problem. While there are database techniques that can be used to prevent this type of problem, I suspect the programmers decided that precise view counters are not so important that they need it; there are performance implications.

Thank you very much.
And I hope it will be more and more better from now on.

Hi BBO:


I'm perfectly sure it is working correctly on the BBO view count now., and I can't find any problem about it.
Thank you,and again

Best Regards

It looks like this is happening again. This thread:

http://www.bridgebas...-bbo-td-ruling/

has been around for several days, and I know I viewed it, but it says 0 views. I guess it's a bug, but I don't know what to do about it. When I looked at the code, it seemed like it should work.

[barmar]

I ran the "Update Topic Views" task manually, and it took 3 tries before this view counter updated. It limits itself to 30 seconds, so it wasn't able to update all the topics in one run, and I think the problem is that it was never catching up during the scheduled runs.

I've changed it to run every hour instead of every 3 hours, I hope this should allow it to keep up.
