We switch to using iterators introduced in Go 1.23 to make iteration alloc-free and fast. And since element removal is allowed while iterating a map, this also means we don't need to even copy the slice any more. While here, we also address the comment https://github.com/mattermost/mattermost/pull/30178#discussion_r1954862151. I have simply gone back to using []string as the map entry rather than a type alias or a redirection with a struct. https://mattermost.atlassian.net/browse/MM-63130 ```release-note NONE ``` * Changed back nil to len ```release-note NONE ``` * fixing unused assignment ```release-note NONE ``` * add benchmark ``` goos: linux goarch: amd64 pkg: github.com/mattermost/mattermost/server/v8/channels/app/platform cpu: Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz │ old.txt │ new.txt │ │ sec/op │ sec/op vs base │ HubConnIndexIterator/2_users-8 93.53n ± 1% 38.09n ± 1% -59.27% (p=0.000 n=10) HubConnIndexIterator/3_users-8 106.30n ± 0% 38.41n ± 1% -63.86% (p=0.000 n=10) HubConnIndexIterator/4_users-8 111.30n ± 1% 38.66n ± 1% -65.27% (p=0.000 n=10) geomean 103.4n 38.39n -62.89% │ old.txt │ new.txt │ │ B/op │ B/op vs base │ HubConnIndexIterator/2_users-8 16.00 ± 0% 24.00 ± 0% +50.00% (p=0.000 n=10) HubConnIndexIterator/3_users-8 24.00 ± 0% 24.00 ± 0% ~ (p=1.000 n=10) ¹ HubConnIndexIterator/4_users-8 32.00 ± 0% 24.00 ± 0% -25.00% (p=0.000 n=10) geomean 23.08 24.00 +4.00% ¹ all samples are equal │ old.txt │ new.txt │ │ allocs/op │ allocs/op vs base │ HubConnIndexIterator/2_users-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=10) ¹ HubConnIndexIterator/3_users-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=10) ¹ HubConnIndexIterator/4_users-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=10) ¹ geomean 1.000 1.000 +0.00% ¹ all samples are equal ``` ```release-note NONE ``` * ForChannel test as well ```release-note NONE ``` * review comments ```release-note NONE ``` * fix lint errors ```release-note NONE ``` --------- Co-authored-by: Mattermost Build <build@mattermost.com>
