Thanks Joe for the info, my input filter is now behaving itself again.
I've not seen any FLUSH buckets yet so I doubt I will as we are running
the bare minimum of modules. I'll let you know if I do though.
One last question, when I don't see the EOS bucket should I return a
certain APR_ error code to say the POST request hasn't finished yet. I'm
currently return APR_OK and this seems to work.
Cheers,
Martin.

this expected?
You should definitely expect that. Don't assume that the entire
content will always come in the same way. In this kind of development
architecture (where anyone can build a module), we should expect the
unexpected.
I assume it is so I have to alter my filter to handle partial
bucket brigades.
If so, I take it I can infer a partial brigade by the fact that the
EOS bucket is not present?
Whilst looking through other input filters I notice they handle FLUSH
buckets, for my input filter I take it I can ignore these buckets as
all I'm trying to do is extract the POST data to a buffer and then
process it without altering it.
If the brigade doesn't have that EOS, there is more to the stream to
be read. When you see the FLUSH bucket, you should really be passing
the brigade on to the next chain (FLUSH buckets are created when the
brigade needs to be split).
I had originally thought that FLUSH buckets were output buckets to
prevent the client from waiting too long. Are you seeing these on an
input chain? If so, what other modules are involved? I'm curious for
my own understanding of how other modules might effect some of the
stuff I have written.
I noticed that one module's input filter ignored sub requests, does
anyone know when sub requests occur within the input filter phase and
whether I can ignore these too.
The input's have already been done when a sub request is created.
Usually, a sub request is happening when an output filter or a content
generator are being called, so I'm not sure a sub-request will see the
input from the parent filter.
Many Thanks,
Martin.
That is what the list is for. Hope you can get things straightened out!
