10bdd912d6 Treat meta[property] as a space-separated list (#10604)
The @property attribute in HTML is a space-separated list of values.
This change normalizes whitespace and finds the desired value in
the list instead of requiring an exact single-value match.

40e5d2303b Validate HTTP response length while receiving (#6891)
to_s method of HTTP::Response keeps blocking while it receives the whole
content, no matter how it is big. This means it may waste time to receive
unacceptably large files. It may also consume memory and disk in the
process. This solves the inefficency by checking response length while
receiving.

54b273bf99 Close http connection in perform method of Request class (#6889)
HTTP connections must be explicitly closed in many cases, and letting
perform method close connections makes its callers less redundant and
prevent them from forgetting to close connections.

3bc8924940 Don't capture scheme-less URLs in the status (#5435)
Specifically, this fixes status length calculation to be same as JS side.

BTW, since this pattern used in not only preview card fetching, we
should extract it (with twitter-regex?) and write tests I think.

35ec1c91e3 Fix some failure cases on FetchLinkCardService (#5347)
* If OEmbed response doesn't have a required property `type`, ignore it.
  e.g. `NoMethodError: undefined method 'type' for ...`
* If we failed to detect encoding, fallback to default behavior of Nokogiri.
  e.g. `KeyError: key not found: :encoding`

596dab06e9 Support OpenGraph video embeds (#4897)
* Support OpenGraph video embeds

It's not really OpenGraph, it's twitter:player property, but it's
not OEmbed so that fits. For example, this allows Twitch clips to
be displayed as embeds.

Also, fixes glitch-soc/mastodon#135

revisit URLs after 14 days

f8fe394e7a Fix an error when TagManager.local_url? is called with a bad URI (#3701)
TagManager.local_url? was sometimes called with an URI with a nil host,
leading to a crash in TagManager.local_url?. This fixes moves the
already-existing uri.host.blank? check in front to avoid this case.
