allow URL-unsafe characters inside raw JDBC connection-uri

[gerrit-hntschl]

ragtime.core/connection tries to parse the raw-connection-string as a URI which fails if the string contains unsafe characters like %.
Our password contained such characters which lead to java.net.URISyntaxException: Malformed escape pair ... when trying to run lein ragtime migrate.
Not sure if proposed fix is a hack, otherwise unsafe characters would have to be percent-encoded inside the project.clj/profiles.clj and parsed inside ragtime, which only adds confusion IMHO.

Cheers!

What happens when the password is percent-encoded? In theory JDBC should be decoding any percent-encoded passwords.

Received an error because of AUTHENTICATION FAILED and so on. Didn't dig a lot deeper though.

What database are you using?

[gerrit-hntschl]

Actually calling (map->SqlDatabase {:connection-uri url}) with the url containing the unencoded % worked just fine.

PostgreSQL

[weavejester]

Which version of Postgres?

[gerrit-hntschl]

9.3.3 and driver [postgresql "9.1-901-1.jdbc4"]

[weavejester]

Okay, I'll run some tests when I get a spare minute. I want to ensure that Postgres really does handle URLs incorrectly before adding any hacks to get around this.

In the meantime, you can use map->SqlDatabase, correct?

[gerrit-hntschl]

Yeah, we just changed the password 🙈 so we can use lein ragtime migrate during deployments.

Thanks!
