Jon Siwek commented on BIT-1338:
--------------------------------
The earliest point that new mime type information is available is in the
file_mime_type event which now comes after file_new/file_over_new_connection.
Can you extract what you need at that time? E.g.:
{code}
event file_mime_type(f: fa_file, mime_type: string)
{
if ( f?$http )
print "file_mime_type", f$http;
}
{code}
> http response mime types uninitialized in file_over_new_connection event

> Key: BIT-1338
> URL: https://bro-tracker.atlassian.net/browse/BIT-1338
> Project: Bro Issue Tracker
> Issue Type: Problem
> Components: Bro
> Affects Versions: git/master
> Reporter: Paul Pearce
> Labels: mime
>
> http resp_mime_types (accessed via: connection$http$resp_mime_types) are no
> longer initialized during the file_over_new_connection event. This is new
> behavior between Bro v2.3 and git/master.
> The following snippet shows the new behavior on one of the included bro test
> traces.
> {code:bash}
> $ bro_v23 -e 'event file_over_new_connection(f: fa_file, c:connection,
> is_orig:bool){ print c$http?$resp_mime_types; }' -r
> bro/testing/btest/Traces/http/get.trace
> T
> $ bro_git -e 'event file_over_new_connection(f: fa_file, c:connection,
> is_orig:bool){ print c$http?$resp_mime_types; }' -r
> bro/testing/btest/Traces/http/get.trace
> F
> {code}
> It's worth pointing out that ultimately the resp_mime_types field does get
> set for subsequent events.
> {code:bash}
> $ bro_v23 -e 'event http_message_done (c: connection, is_orig: bool, stat:
> http_message_stat){ if (!is_orig) print c$http?$resp_mime_types; }' -r
> bro/testing/btest/Traces/http/get.trace
> T
> $ bro_git -e 'event http_message_done (c: connection, is_orig: bool, stat:
> http_message_stat){ if (!is_orig) print c$http?$resp_mime_types; }' -r
> bro/testing/btest/Traces/http/get.trace
> T
> {code}
