I have just updated my favourite XMPP server - ejabberd - from 17.01 to 17.04.

After rebuilding fresh ports in poudriere, upgrading was as easy as typing pkg upgrade, followed with service ejabberd restart (underlying OS is FreeBSD, of course). Service came back completely functional after restart, but I have noticed some warnings in my ejabberd.log:

2017-06-29 14:10:33.147 [warning] <0.62.0>@ejabberd_s2s_out:maybe_report_huge_timeout:455 value '10000' of option 'outgoing_s2s_timeout' is too big, are you sure you have set seconds?
2017-06-29 14:10:33.177 [warning] <0.62.0>@ejabberd_config:emit_deprecation_warning:1436 Module mod_http_bind is deprecated, use mod_bosh instead
2017-06-29 14:10:33.232 [warning] <0.62.0>@ejabberd_config:emit_deprecation_warning:1428 Module mod_vcard_ldap is deprecated, use mod_vcard with 'db_type: ldap' instead

None of the above warnings seem to have negative impact in ejabberd-17.04, but I don't like warnings in my logs, so I corrected them anyway.

As for outgoing_s2s_timeout, since 17.04 it should be specified in seconds, not in milliseconds, as confirmed here. I have changed value from 10000 to 10 to retain the old behaviour.

As for mod_http_bind, all I needed to do is to rename it, so mod_http_bind: {} becomes mod_bosh: {}

Finally, my mod_vcard_ldap config section used to look as follows on 17.01:

  mod_vcard_ldap:
    search: false
    ldap_vcard_map:
      "NICKNAME": {"%u": []}
      "FN": {"%s": ["displayName"]}
      "FAMILY": {"%s": ["sn"]}
      "GIVEN": {"%s": ["givenName"]}
      "ORGNAME": {"%s": ["company"]}
      "ORGUNIT": {"%s": ["department"]}
      "LOCALITY": {"%s": ["l"]}
      "DESC": {"%s": ["description"]}
      "TEL": {"%s": ["mobile"]}
      "EMAIL": {"%s": ["mail"]}

Renaming mod_vcard_ldap to mod_vcard and inserting db_type: ldap was enough to get rid of the warning. Here's how related config section looks now:

  mod_vcard:
    db_type: ldap
    search: false
    ldap_vcard_map:
      "NICKNAME": {"%u": []}
      "FN": {"%s": ["displayName"]}
      "FAMILY": {"%s": ["sn"]}
      "GIVEN": {"%s": ["givenName"]}
      "ORGNAME": {"%s": ["company"]}
      "ORGUNIT": {"%s": ["department"]}
      "LOCALITY": {"%s": ["l"]}
      "DESC": {"%s": ["description"]}
      "TEL": {"%s": ["mobile"]}
      "EMAIL": {"%s": ["mail"]}

Now my ejabberd logs are sparkling clean once again :)
