best you get gibberish.  Much worse things can happen depending
on the OS.

This can happen when autoindex isn't loaded.

On AIX, I had a directory file which was reported to be 1536 bytes
in size.  mmap() failed so we went to the fall-back logic.
The first read() got 624 bytes and the next read() got 0
(supposedly EOF).  This confused us greatly, we kept allocating
buffers and reading and exercised the paging space.

ap_add_output_filter_handle()

There are many places in the core modules where we do
ap_add_input_filter() or ap_add_output_filter() on a
hardcoded filter name (e.g., "CORE" or "BYTERANGE").
This requires a string-to-filter mapping that wastes
CPU time.  (Even though the string lookup uses a trie
for speed, it still ranks as a big consumer of CPU time
because of the large number of filters added per request.)

The new ap_add_*_filter_handle() functions will allow
us to skip the string-to-filter mapping in cases where
the module adding the filter happens to have the
ap_filter_rec_t* for the registered filter (e.g., because
it's the same module that registered the filter in the
first place).

  No.  I don't like this patch.  I like what it does [shared scoreboard
  for Windows, finally] but not how it's implemented.

  However it works, and is equally crufty to what already exists for
  win32 listeners and other exposed data within scoreboard.c.

  To do this right, we need to drop all the external references to data
  within the scoreboard, and add an accessor for remaining bits (such as
  Win32's need for direct access to the apr_shm_t.)  And within Win32,
  we need to stack all this _within_ the pre-mpm hook.  But those are
  missions in and of themselves.

to determine if MIME-continuation should occur.

Notes:
- ap_rgetline has a new prototype.
- ap_rgetline returns APR_ENOSPC when we are out of buffer space.

All direct callers of ap_rgetline are now adjusted to handle this new API.
ap_getline will mimic the old API for now.

separate from the input filter mode type.

We also no longer look at readbytes to determine the method of
filter operation.  This makes the use of filters more obvious and
allows a wider range of options for input filters modes.

To start with, the new input filter modes are:

AP_MODE_READBYTES (no more than *readbytes returned)
AP_MODE_GETLINE (old *readbytes == 0 case)
AP_MODE_EATCRLF (old AP_MODE_PEEK)
AP_MODE_SPECULATIVE (will be used in a future ap_getline rewrite)
AP_MODE_EXHAUSTIVE (old *readbytes == -1 case)
AP_MODE_INIT (special case for NNTP over SSL)

The block parameter is an apr_read_type_e: APR_BLOCK_READ, APR_NONBLOCK_READ

This also allows cleanup of mod_ssl's handling in the getline case.

You will not see ENOBUFS at 10.20 because the kernel

ENOBUFS at 11.0 TCP/IP is quite possible, and could

ingnore ENOBUFS.

  This patch eliminated from the _SHARED_ segment of the scoreboard all
  pointer math.  This is required for portable scoreboards.

  vhost becomes the 'vhost name string' so it now survives ap_generation
  clicks.  next was apparently never used.

  This patch also accounts for the changes to the apr_shm api, and gives
  Win32 the magic of a shared scoreboard.

  Breakage aplenty on non-win32 platforms, I suspect, but this radical
  surgery, and culling of unused functions, was really, really needed.
