bug in club members endpoint: members in "all_time" who have been online in the last week

I'm seeing some club members show up in the "all_time" group or "monthly" whom I expected to be in "weekly". At first I put it down to caching (one had been away and returned ~24-36 hours ago) but this one is plain wrong.

Documentation:

https://www.chess.com/news/view/published-data-api#pubapi-endpoint-club-members

Endpoint:

https://api.chess.com/pub/club/asger-s-great-viking-warriors/members

A big chunk of data, but I don't want a cache refresh to render this bug report "well, maybe he was confused ... let's see if it happens again"   (Been there, done that, both sides.)

A little different to turning up in "all_time" as he is shown to be in post #2.

If the profile is trustworthy I can use it, and sometimes I need data from it anyway in which case it's free, but if I don't need data from the profile looking up a few hundred member profiles for the size of teams I'm working with is unattractive. Which is news to nobody I guess as I suppose I'm stating the obvious.

@skelos We have updated how often the Club Members endpoint is refreshed. It should happen every time a member visits the Club. This should help to keep the data fresh.

Updated for everyone, or only for that member? Because I'm still seeing dubious data, and believe I'll have to switch to per-member profile data and last_login.

My current example is @bulletheadbilly and Black Stone:

Have I been caught by unfortunate caching? If I recall correctly it was originally documented that the category a player would show in could be out of date by up to 24 hours. Thus if @bulletheadbilly had not been online for a week but came back today ... maybe the output is correct to show him in "monthly".

Thoughts, please?

Rather than continue to chase this, perhaps the weekly/monthly/all_time divisions should simply be dropped?

As originally documented they were going to be up to 24 hours behind, and I didn't really see the use. Then I decided it was a rough-and-ready breakdown and might be useful, but it's actually bitten me once now when I relied on it before I realised it was broken, and now that it's supposedly unbroken I've either chanced on awkward caching on my very first test, or it's not fixed.

Other than runtime, once I code to go and use the player's profile and last_login (which on minimal testing to date looks OK) there won't be much reason to come back to this.

I regret to inform you that whatever the improved updating method is, it doesn't appear to work. At all, I suspect.

My test group this time is Battle For Victory. All the "weekly" values look sensible. The "monthly" values most emphatically do not, even allowing for the data to be 24 hours old. I have highlighted values that are clearly >24 hours old, and indeed in the "monthly" data there is only one member who hasn't been online in the last week!

"monthly"

The "all_time" data is  bit big to post, but selected excerpts which should clearly be reported earlier include:

Right now I don't – and can't – trust this data at all. It looks like it's not 24 hours old but 72 hours old, at least.

A cursory look shows data that should be in "monthly" but is in "all_time":

Rather than fix this, I now propose biting the bullet and making a breaking change. Just give us the member list, with or without last_online time and not the tri-part split we have now but can't use.

If you wish to see if a player is active on the website, then the "last_online" of the player profile is the correct endpoint to hit. That seems to be what you are doing.

The club activity groups (weekly, monthly, all_time) are based solely on the player's interaction with club content — forums, news, the club homepage (notes), and so forth. Many people will be online (livechess, a mobile app, tactics) and will never view much of the website and only rarely visit a club. Many players rely on notifications for their club interactions, and do not visit the club pages at all. As such, last_online is only rarely going to be coordinated with the club activity groupings.

I have just reviewed the code. I believe that the activity that counts toward resetting the player's club-activity date are

• Viewing the club homepage
• Viewing the clubs news index or a specific news article (but not the notification message received that the news was published)
• Viewing the club's forums or a specific forum thread
• Changing their club settings, including modifying their membership; for admins, this includes inviting or authorizing new members
• Viewing the club's tournament, team match, or votechess lists (but not, it appears, viewing or participating in those games!)
• Viewing club membership lists or running a related search, or viewing the leaderboards for the club

Does that help? We can add this to the documentation.

Please, add those details to the documentation.

I had totally the wrong idea about what the split was. It now makes sense and might be useful to me.

If after you've added that information you'd like me to review it and see if I can still come up with a way to interpret it and confuse it with last_online, I will, but I doubt very much that it will be possible. Perhaps I didn't read carefully enough in the first place.

Sorry for the confusion, but that's good information, so it's not all loss. (Or I'm looking for the silver lining in the cloud, or both.)

I'm on the way to having a small USA locate virtual server that won't go through Wi-Fi, VPN and across the Pacific. It will be interesting to see how that speeds things up for me because I think latency is the killer at the moment even with persistent connections.
