Fails to build on systems with OpenSSL 1.1.1

[Fanael]

See sfackler/rust-openssl#994.

Serenity pulls in native-tls 0.1.5, which depends on an old version of openssl that doesn't build on systems with OpenSSL 1.1.1.

[Celti]

There's a compat branch that's working just fine (for me) with openssl v1.1.1 at ishitatsuyuki/rust-openssl, with a PR open against rust-openssl v0.9.x.

Try it yourself with a patch entry in Cargo.toml:

[patch.crates-io]
openssl = { git = "https://github.com/ishitatsuyuki/rust-openssl", branch = "0.9.x" }

[Lymia]

The PR has been closed, because apparently "0.9 is no longer supported" means "even if someone else does the work for us". :|

Gonna start digging into upgrading some stuff on the serenity side to fix this, because as of now you can't build Serenity under Arch Linux, which is a huge pain.

Unfortunately there's another dependency that pulls in the old native-tls code: a crate called evzht9h3nznqzwl, which hasn't been updated in a year and has a description that makes you question why it was even used in the first place. Looks like it's an implementation of websockets.

That crate is a fork of a websocket crate that fixed several issues at the time of its creation. The current solution until dependencies are worked out is to use the patch mentioned by @Celti. Said patch allows serenity to work as expected on platforms using newer OpenSSL versions.

@Mishio595 What particular issues?

Just swapped it for websockets and all the tests pass. Gonna try running it.

This causes any large payloads to often fail, for example GUILD_CREATEs of medium-large size guilds.

Fixed in v0.6.0. Should be closed when it releases.

How about 0.5.x users? I can't upgrade to 0.6 right now because the API is completely changed and it would take more time than I have in the immediate future (I'm looking at an upgrade later this month though).

I just ran apt update && apt full-upgrade on Ubuntu, it upgraded me to OpenSSL 1.1.1, and my Serenity-based bot is down. Even without recompiling, the TLS handshake code fails and it bombs. I'm afraid that's not OK, but the breakage is apparently on the OpenSSL side more than anything, since it breaks code that compiles and runs. I grabbed the hackaround from Celti above (thanks!) so stuff is compiling for now, but oof that isn't pretty.

Since openssl 0.9 doesn't support OpenSSL 1.1.1,so that OpenSSL with old ver is needed
I fix this by manually set OPENSSL_DIR,OPENSSL_LIB_DIR,OPENSSL_INCLUDE_DIR to OpenSSL 1.0.1
