Fixed continuous config appending #83
Conversation

On Heroku the filesystem is ephemeral, so previous run's configs won't exist any more. |

Ah there's a dupe of this, #70 which gives an example scenario. |

The change described in the title is fine, but I am suspicious of the change in connection string parsing. As we don't have tests for this, I don't know how this was validated or how it would work with odd input.
I suggest breaking that change into another pr so we can test and qualify it without blocking the config appending.

@gregburek I split this into two separate pull requests. |
The users.txt file must be appended to as multiple postgres dbs in POSTGRES_URLS, we need to add all the creds to the users.txt file, not reset it for every entry in POSTGRES_URLS.

yeah this is inside the for loop, so it must be append only. Fixed in #89
Otherwise running `start-stunnel <COMMAND>` multiple times (such as in a one-off dyno when running a command and then killing it) will result in an stunnel.conf that has invalid syntax due to the global options being appended after the per-server header. Based on: heroku/heroku-buildpack-pgbouncer#83
Fixed the issue where the stunnel-pgbouncer.conf, user.txt and pgbouncer.ini files are being repeatedly appended on server restarts, instead of erasing and restarting.
Also fixed the DATABASE_URL parse to not fail on missing passwords.
