Warnings about "closing unused connection"

[juliasilge]

I have started seeing warnings about "closing unused connection" when I read/write pins:

Warning messages:
1: In for (i in seq_along(specs)) { :
  closing unused connection 8 (/private/var/folders/hv/hzsmmyk9393_m7q3nscx1slc0000gn/T/RtmpbFtlMX/file2ae6ad2a5fe.tar.gz)

I looked at this a little today, and I believe this is only happening for pins on Connect and it's these local files in the temp directory that end up with connections that do not get closed:

pins-r/R/board_connect.R

Lines 293 to 294 in 45c1634

	bundle_dir <- rsc_bundle(board, name, paths, metadata, x, preview_data = preview_data)
	bundle_file <- fs::file_temp(ext = "tar.gz")

The connections for files like filea970b3016d7 are getting opened here:

pins-r/R/board_connect.R

Lines 308 to 311 in 45c1634

	json <- rsc_POST(
	board, rsc_v1("content", content_guid, "bundles"),
	body = httr::upload_file(bundle_file)
	)

The connections for files like filea97019f844d7.tar.gz are getting opened here:

pins-r/R/board_connect.R

Lines 316 to 319 in 45c1634

	json <- rsc_POST(
	board, rsc_v1("content", content_guid, "deploy"),
	body = list(bundle_id = bundle_id),
	)

I think something similar is reported in https://stackoverflow.com/questions/79584832/resource-busy-error-when-using-pins-package-with-google-cloud-storage-in-r

I think it's httr actually: r-lib/httr#761
