add a bit of error checking to the mod_cgid daemon's logic to read

it isn't perfect (EINTR, partial reads) but it is good enough to
avoid segfaulting if some code tries to verify that cgid is active

implement a common function for getting a socket and trying to connect
to the target host; use that common function for proxy HTTP and proxy
CONNECT
In that new function, fix this problem:
Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
when we can't get a socket in the specified address family. We may
have gotten back an IPv6 address first and yet our system is not
configured to allow IPv6 sockets.
An example host is www.ipv6.org. The first address I get back is
an IPv6 address, but my machine may not be configured to allow an
AF_INET6 socket.
Before the fix: The apr_socket() failure was fatal.
After the fix: When apr_socket() fails, we go to the next address from
the resolver, successfully create a socket in the
specified family (AF_INET), and all is well.

As hinted on dev@httpd, change filter naming schemes to match our
expectations of their usage.
The reason that we should make this change now is that we have changed
the implied meaning of AP_FTYPE_HTTP_HEADER - some users of this should
be PROTOCOL while others should be CONTENT_SET. In order to clarify it,
toss all of the bogus names and force the filter writers to make sure
they understand what they are doing.
CONTENT_SET is new (horrible name - change if you have better idea), but
it indicates that it should run between RESOURCE and PROTOCOL.
mod_deflate is the ideal CONTENT_SET filter.
The changed type names are:
CONTENT is now RESOURCE.
HTTP_HEADER is now PROTOCOL. However, most filters that used HTTP_HEADER
may want CONTENT_SET. (Only things like POP and HTTP belong as PROTOCOL.)
MMN bump since all filters need to be recompiled due to filter reordering.

We need to setup protocol filters for the fake request. If we don't,

There is no reason to insert the protocol filters in the insert_filters
phase. This moves us to inserting the filters in the create_request
phase. This makes more sense, because now the protocol filters are attached
to the request as soon as possible. Previously, some requests never
called the insert_filters phase, so they don't get the filters. Think
redirects for reqeusts that never call insert_filters.

Remove the prev pointer from the filter chain. This removes
the complexity of trying to set the filter chain correctly, with the
side-effect of forcing us to walk the entire chain whenever we add
a filter. Since the filter chains are small, the decrease in
complexity is worth it.

Bail on computing the amount of bytes in a brigade if any of the buckets
have indeterminate length (e.g., a pipe bucket). Passing an invalid length
into mod_mem_cache can cause it to overflow its cache buffer.
Ensure that net_time filter isn't added on subreqs - we assume that it is
added on !r->main requests. This led to infinite loop/SEGV when dealing
with anything that created a subreq.
(I don't think core_create_req is a good place for adding this filter.)

Adding the same filters over and over again used to be okay, because
we would lose the extra filters. Now, if a filter is added, it is run.
Unfortunately, this can cause an infinite loop, or it can cause request
headers to appear twice. This commit removes two instances in the core
where we were inserting filters for a second and third time. The bug
was that error responses were causing infinite loops.
This also removes the reset_filters function, which did the exact
same thing as add_required_filters. The two functions were both called
in error conditions, which was part of what caused this bug.

If we insert a protocol filter before we insert a request filter, we
must set the r->output_filter to r->proto_output_filter. If we don't,
then as soon as we insert the request filter, the protocol filter will

Classify some of the input filters as the correct types. Previous to
this patch, the type wasn't too important, because all filters were
put on the same list. After this patch, the filter type is very important,
because there are three different types of filters, and they are all treated
differently, namely:
CONNECTION: Filters of this type are valid for the lifetime of this
connection.
PROTOCOL: Filters of this type are valid for the lifetime of this
request from the point of view of the client, this means
that the request is valid from the time that the request
is sent until the time that the response is received.
CONTENT: Filters of this type are valid for the time that this
content is used to satisfy a request. For simple requests,
this is identical to PROTOCOL, but internal redirects
and sub-requests can change the content without ending
the request.
It is important to realize that the three major types above are actually
broken down into smaller groups in the code, to ensure that the ordering
of filters is always correct.

This finishes the mod_dir/mod_negotiation bug. This final part of the
solution ensures that we don't lose filters if they are added later than
we expect. The problem could be seen if a connection filter was added
after a request-based filter was added in the past. The problem was that
the request-based filters pointed to the first filter in the connection
record, so the new connection filter was never called. Now, all filters
are put on their correct filter lists, and we are sure to always update
all pointers when adding a filter.
Ryan Bloom [Sun, 3 Mar 2002 02:15:52 +0000 (02:15 +0000)]
Fix the mod_dir/mod_negotiation bug, where redirects and sub requests
were not getting the correct filters. This is done by creating a location
in the request rec that holds protocol level filters. Protocol level
filters survive for one request, from the time the request is received
from the user to the time the response is sent. r->output_filters now
stores the request level filters, which are only valid for the lifetime
of one request_rec.
This patch works, but it is not complete. The second half of the problem
is that add_any_filter doesn't check where it puts the filters that it
adds, so it is possible for filters to be put on this wrong list, and
for filters to be lost completely during request processing. That half
of the fix will be coming in the next day or so.
