mod_http_oauth2: Allow revoking a token without OAuth client credentials
If you have a valid token, and you're not supposed to have it, revoking
it seems the most responsible thing to do with it, so it should be
allowed, while if you are supposed to have it, you should also be
allowed to revoke it.

--- summary: JSON Log Sink --- Conifiguration ============== Here we log to `/var/log/prosody/prosody.json`: ``` {.lua} log = { -- your other log sinks info = "/var/log/prosody/prosody.log" -- add this: { to = "json", filename = "/var/log/prosody/prosody.json" }; } ``` ## UDP Alternatively, it can send logs via UDP: ```lua log = { { to = "json", udp_host = "10.1.2.3", udp_port = "9999" }; } ``` Format ====== JSON log files consist of a series of `\n`-separated JSON objects, suitable for mangling with tools like [`jq`](https://stedolan.github.io/jq/). Example (with whitespace and indentation for readability): ``` {.json} { "args" : [], "datetime" : "2019-11-03T13:38:28Z", "level" : "info", "message" : "Client connected", "source" : "c2s55f267f5b9d0" } { "args" : [ "user@example.net" ], "datetime" : "2019-11-03T13:38:28Z", "level" : "debug", "message" : "load_roster: asked for: %s", "source" : "rostermanager" } ``` `datetime` : [XEP-0082]-formatted timestamp. `source` : Log source, usually a module or a connected session. `level` : `debug`, `info`, `warn` or `error` `message` : The log message in `printf` format. Combine with `args` to get the final message. `args` : Array of extra arguments, corresponding to `printf`-style `%s` formatting in the `message`. Formatted message ----------------- If desired, at the obvious expense of performance, the formatted version of the string can be included in the JSON object by specifying the `formatted_as` key in the logger config: ``` {.lua} log = { -- ... other sinks ... { to = "json", formatted_as = "msg_formatted", filename = "/var/log/prosody/prosody.json" }; } ``` This will expose the formatted message in the JSON as separate `msg_formatted` key. It is possible to override existing keys using this (for example, the `message` key), but not advisible.
