Add an error condition to the filter code. Basically, if somehow we get
to the very bottom of the filter stack and nobody has written anything to
the network, then we need to return an error.

Initial Filtering code. This uses a bucket brigade scheme to allow modules
to add and modify data while processing a request. The docs still need
to be updated, and a simple html page needs to be created explaining all
of this.
The only filter currently in the code is the core filter. This filter
takes a bucket brigade and writes it to the network through the buff
structure. In time, the buff will go away completely.
More filters will need to be written.

- Log proper error message instead of error code on failure
- In case of error caused by an invalid file name, don't return an empty

Finish (almost) Ryan's change of apr_filter_t back to ap_filter_t so
that apache builds again.
AFAICT, there is one last occurrence of apr_filter_t in ryan.patch.
After this config file is parsed, the only statement in the config
tree is the last statement in the IfModule container ("RewriteRule blah
blah").
The problem is that when ap_build_config_sub() handles this type of
construct, it moves *current to the end of the list before returning.
If this construct were the first thing in the file, the caller would
set conftree to *current, not realizing that there were list elements
before *current. The caller doesn't have addressability to those list
elements.
With this change, ap_build_config_sub() sets *conftree before
walking *current to the end of the list.

Fix the Perchild MPM. This does work now. This change has us using
socketpair instead of sockets created with AF_UNIX. There is very little
chance this will work anywhere other than Linux, but it is a start. I
have a machine with two virtual hosts, which are started as two different
users. When I make requests for each virtual host, they pass the request
to the correct child process. It is possible for a virtual host to have
multiple child processes all with the same user ID, and they all share
the responsability for answering requests.
There are a lot of bugs in this code, and it is not for the faint
hearted, but it works, and that's saying quite a bit in my mind.
Docs coming tomorrow. Right now, it's time to sleep.

More progress with the perchild MPM. This is serving pages again, but
only when the request is accepted by the server that supposed to serve the
result. The biggest problem right now is descriptor passing. This isn't
likely to work anyplace other than Linux right now either.

Update the perchild MPM. This does not work, but that is because Linux
doesn't use any of the standard methods for passing around file
descriptors. I am setting this aside for a day or two, and then I will
come back and finish the implementation on a new OS. This is highlighting
the need for descriptor passing in APR.
Ryan Bloom [Tue, 1 Aug 2000 18:58:19 +0000 (18:58 +0000)]
Complete redesign of this MPM. This is almost working now.
HOW IT WORKS:
In the config file, the sysadmin specified:
ChildPerUserID uid gid num_processes
and in each virtual host:
AssignUserID uid gid
The MPM creates a unix domain socket for each uid/gid pair, and if any
child processes are left over, one for the default user and group
specified in the main config.
When a child process is started, it looks at what it's user id and group
id are supposed to be. It then inserts the correct socket into it's
listen array, and switches to the uid and gid specified.
When a request comes in, whichever child gets the request looks at which
child process it is actually for, and if it isn't for the current
process, the request gets forwarded through the unix domain socket to the
correct child process. From there, processing continues normally.
Currently, no requests are forwarded, but everything seems to be working.
Ryan Bloom [Tue, 1 Aug 2000 17:36:13 +0000 (17:36 +0000)]
Add a NO_DETACH environment variable to all MPMs that understand
ONE_PROCESS. This allows Apache to start up without detaching from
the controlling terminal, but also not going into single process mode.
The main purpose of this patch is to make it very easy to debug the
child process startup code.
