Ref: #24638

IMO, parallelizing might run out server resources more quickly. Gitea shouldn't use a lot of go-routine in a web handler.

And add a comment about how many repositories there could be at most.

// at most there are dozens of repos (limited by MaxResponseItems), so it's not a big problem at the moment

(which is limited by RepoPagingNum)

Are you sure?

The PageSize comes from PageSize: convert.ToCorrectPageSize(ctx.FormInt("limit")),, and ToCorrectPageSize says:

else if size > setting.API.MaxResponseItems {
		size = setting.API.MaxResponseItems
	}

I see, limit is RepoPagingNum but this condition overrides it

Luckily it's checked, that's what I have double-checked.

Otherwise, attackers could to "limit=99999" to DoS the server.

It's fine if you want it serialized, there is such a small number of calls it doesn't matter you are right, the previous code was unsafe
