Any way to throttle calls to get_status?

[RichardMN]

It's more of a question than a comment...

I have a frame with a number of toot ids generated from elsewhere and I want to try to pull additional information from them. This ends up looking something like...

  icymibot_expanded <- icymibot_data |>
    top_n(500,created_at) |>
    rowwise() |>
    mutate(details=get_status(toot_id)) |>
       ...

But it crashes out after 300 rows (as far as I can tell). Is there a way to tell rtoot as a whole to back-off and that I'd rather that it chill a bit between requests rather than it hammer the server in an asocial manner and get told to stop (Status code: 429)?

hmm interesting so 300 calls is the 5 minute rate limit but we do have rate limit checks implemented(i.e. sleep until reset of rate limit). Can you share a reproducible example so I can check whats going on?

[RichardMN]

It'll be about a week before I can put together a reproducible example but I'll try to do so when I can.

Dont worry, I am moving house atm so take your time

This isn't a reprex but an outline of how I appear to be working around it for now. The following code managed to pull all 500 lines of what I was trying - or at least it managed to return a tibble with 500 rows, though some of them have NAs which I'll deal with later. I think that it may have been that I had a problematic id which made get_status fail with an error. Wrapping it with slowly means I'm less worried about hammering the server, and possibly lets it fail in a controlled manner.

slow_get_status <- slowly(possibly(get_status, otherwise = NA), rate_delay(2.5), quiet=FALSE)
icymibot_rowwise <- icymibot_data |>
  top_n(500,created_at) |>
  rowwise()
icymibot_details <- icymibot_rowwise |>
  mutate(details=slow_get_status(toot_id))

[schochastics]

Could you try to run this "unvectorized", something like:

icymibot_rowwise <- list()
for(i in seq_len(nrow(icymibot_rowwise)){
    icymibot_rowwise$details[[i]] <- get_status(icymibot_rowwise$toot_id[[i]])
}

If this bugs out after 300, then I think there might be an issue with our rate limit checking

I can confirm that error "Status Code: 429" persists if you use a for loop as the one above.
When I wrapped the statement in a tryCatch block to skip a line upon error, it had the same
error for all subsequent lines (suggesting that it is indeed the ratelimit).

[schochastics]

Did you use the current version 0.3.4? We attempted to implement a better 429 handling there, which apparently needs more work if you are on the most recent version

[fjnitsch]

Sorry my bad. Updated the package and now get the "too many requests. Sleeping for 5 minutes". Thank you!

[RichardMN]

Sorry not to come back on this. I ended up wrapping my calls in slowly and possibly and this has been slow but steady and works:

slow_get_status <- slowly(possibly(get_status, otherwise = NA), rate_delay(2.5), quiet=FALSE)
slow_get_reblogged_by <- slowly(possibly(get_reblogged_by, otherwise = NA), rate_delay(2), quiet=FALSE)

I may look at trying to run it without this wrapping again but I worry about hammering my server with repeated runs.

I'm getting this 429 status multiple times within a single function, get_account_following() or get_account_followers(), when the limit is larger than 300 * 40, that is, trying to get all the followings / followers of highly connected accounts. I wonder this is because the server itself is overloaded, or if the functions should sleep between pages. (Honest question, I don't know about writing API clients.)

Update: I ended up doing something like this and still get occasional rate limit messages (and 503 errors) even though I'm not using the API through other means, so I guess the problem is the instance itself is struggling.

max_id = NULL
for (i in seq.int(ceiling(40L/page.size))) {
  api_response = get_account_followers(id, max_id, ...)
  # do stuff with api_response
  Sys.sleep(1)
  if (rtoot:::break_process_request(api_response, TRUE, verbose)) break
  max_id = attr(api_response, "headers")$max_id
}
