even 2 billion is way larger than even extreme operating values
expected for the members in base.h
include some structs directly in struct server, rather than by ptr
code reuse, simplification, and inlining
remove excess calls to chunkqueue_remove_finished_chunks()
(it may still be possible for there to be an empty chunk in chunkqueue
if nothing were written to a temporary file (need to verify this), so
preserve some calls to chunkqueue_remove_finished_chunks() for now)
quickly clear buffer instead of buffer_string_set_length(b, 0) or
buffer_reset(b). Avoids free() of large buffers about to be reused,
or buffers that are module-scoped, persistent, and reused.
(buffer_reset() should still be used with buffers in connection *con
when the data in the buffers is supplied by external, untrusted source)
provide standard types in first.h instead of base.h
provide lighttpd types in base_decls.h instead of settings.h
reduce headers exposed by headers for core data structures
do not expose <pcre.h> or <stdlib.h> in headers
move stat_cache_entry to stat_cache.h
reduce use of "server.h" and "base.h" in headers
move write throttling code from network.c:network_write_chunkqueue()
to connections-glue.c:connection_write_chunkqueue() and fix the code
to use TCP_CORK only on TCP sockets.
large code move, but minimal changes made to code (besides whitespace),
so that code builds
next: need to isolate openssl data structures and config parsing
new directive ssl.read-ahead = "enable"/"disable" to control
SSL_CTX_set_read_ahead(). Default "enable". The "disable" setting
is intended for use on low memory systems with a slow CPU which is
unable to keep up with decryption of large request bodies.

support Transfer-Encoding: chunked request body in conjunction with
server.stream-request-body = 0
dynamic handlers will still return 411 Length Required if
server.stream-request-body = 1 or 2 (!= 0)
since CGI-like env requires CONTENT_LENGTH be set
(and mod_proxy currently sends HTTP/1.0 requests to backends,
and Content-Length recommended for robust interaction with backend)

"request: support Chunked Transfer Coding for HTTP PUT"

fix potential NULL pointer dereference in mod_deflate.c
remove logically dead code in connection-glue.c
add coverity annotations to see if some issues will be reclassified
read all available records from SSL_read(), even if larger than
MAX_READ_LIMIT, since the data is already in memory. openssl is
configured with SSL_MODE_RELEASE_BUFFERS and will release openssl
buffers once records have been read.
Without reading available data, there was a chance that the connection
would hang waiting for a read event on the fd, even though all the
data had already been read from kernel socket buffers and was in openssl
memory waiting to be read with SSL_read().

Set server.stream-request-body = 1 or server.stream-request-body = 2
to have lighttpd connect to backend (CGI, FastCGI, SCGI, proxy)
immediately after parsing request headers, and to stream request body
as it arrives.
default: buffer entire request body before connecting to backend,
in order to avoid tying up (limited) backend resources which are often
implemented using libraries which wait for entire request body before
proceeding.

This allows admin to configure if response is collected in entirety
prior to sending data to client
For compatibility with existing configs, default is existing behavior:
buffer entire response prior to sending data to client
The following are config options, though not all implemented yet
// default: buffer entire request body before connecting to backend
server.stream-request-body = 0
// stream request body to backend; buffer to temp files
server.stream-request-body = 1
// stream request body to backend; minimal buffering might block upload
server.stream-request-body = 2
// default: buffer entire response body before sending to client
server.stream-request-body = 0
// stream response body to client; buffer to temp files
server.stream-request-body = 1
// stream response body to client; minimal buffering might block backend
server.stream-request-body = 2

connection_handle_read()
connection_handle_read_ssl()
connection_handle_read_post_state()
no code changes besides making connection_handle_read() public
(by removing 'static' and adding to connections.h)
i hope it helps with merging stuff back to 1.5
