Note: rrdtool counts do not include HTTP/2 protocol overhead.
Continue to count mod_rrdtool per request rather than per connection
so that data is updated after each request, rather than aggregated
to the end of a potentially long-lived connection with many keep-alives.
reset connection counters per connection, not per request
adjust mod_accesslog and mod_rrdtool usage

NB: r->tmp_buf == srv->tmp_buf (pointer is copied for quicker access)
NB: request read and write chunkqueues currently point to connection
chunkqueues; per-request and per-connection chunkqueues are
not distinct from one another
con->read_queue == r->read_queue
con->write_queue == r->write_queue
NB: in the future, a separate connection config may be needed for
connection-level module hooks. Similarly, might need to have
per-request chunkqueues separate from per-connection chunkqueues.
Should probably also have a request_reset() which is distinct from
connection_reset().
convert all log_error_write() to log_error() and pass (log_error_st *)
use con->errh in preference to srv->errh (even though currently same)
avoid passing (server *) when previously used only for logging (errh)
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
handle_trigger should return HANDLER_GO_ON even on error,
since we want other trigger funcs from other modules to
be able to perform periodic maintenance
centralize most waitpid() handling in core server, with hooks for
modules to be informed of pid and status when a process exits.
This enables faster discovery (and restart) of exited processes,
and also allows for lighttpd to manage backend processes in the
parent (master) process when server.max-worker > 0.
silence compiler warnings if HAVE_FORK is not set
However, if HAVE_FORK is not set, then -Werror was probably passed to
./configure, which is currently a mistake. lighttpd can successfully
compiles src/ with -Werror on many platforms, but ./configure tests
should not be run with -Werror. [gstrauss]
github: closes #81
x-ref:
"Fix warnings"
https://github.com/lighttpd/lighttpd1.4/pull/81
- a lot of code tried to handle manually adding terminating zeroes and
keeping track of the correct "used" count.
Replaced all "external" usages with simple wrapper functions:
* buffer_string_is_empty (used <= 1), buffer_is_empty (used == 0);
prefer buffer_string_is_empty
* buffer_string_set_length
* buffer_string_length
* CONST_BUF_LEN() macro
- removed "static" buffer hacks (buffers pointing to constant/stack
memory instead of malloc()ed data)
- buffer_append_strftime(): refactor buffer+strftime uses
- li_tohex(): no need for a buffer for binary-to-hex conversion:
the output data length is easy to predict
- remove "-Winline" from extra warnings: the "inline" keyword just
supresses the warning about unused but defined (static) functions;
don't care whether it actually gets inlined or not.

* removed almost all usages of buffer as "memory" (without terminating
zero)
* refactored cgi variable name encoding

* remove unused structs and functions
(buffer_array, read_buffer)
* change return type from int to void for many functions,
as the return value (indicating error/success) was never checked,
and the function would only fail on programming errors and not on
invalid input; changed functions to use force_assert instead of
returning an error.
* all "len" parameters now are the real size of the memory to be read.
the length of strings is given always without the terminating 0.
* the "buffer" struct still counts the terminating 0 in ->used,
provide buffer_string_length() to get the length of a string in a
buffer.
unset config "strings" have used == 0, which is used in some places
to distinguish unset values from "" (empty string) values.
* most buffer usages should now use it as string container.
* optimise some buffer copying by "moving" data to other buffers
* use (u)intmax_t for generic int-to-string functions
* remove unused enum values: UNUSED_CHUNK, ENCODING_UNSET
* converted BUFFER_APPEND_SLASH to inline function (no macro feature
needed)
* refactor: create chunkqueue_steal: moving (partial) chunks into another
queue
* http_chunk: added separate function to terminate chunked body instead of
magic handling in http_chunk_append_mem().
http_chunk_append_* now handle empty chunks, and never terminate the
chunked body.

These should all be non critical:
* memory leaks on startup in error cases (which lead to
immediate shutdowns anyway)
* http_auth/ldap: passing uninitialized "ret" to ldap_err2string
* sizeof(T) not matching the target pointer in malloc/calloc calls;
those cases were either:
* T being the wrong pointer type - shouldn't matter as long as all
pointers have same size
* T being larger than the type needed
* mod_accesslog: direct use after free in cleanup (server shutdown);
could crash before "clean" shutdown
* some false positives (mod_compress, mod_expire)
* assert(srv->config_context->used > 0); - this is always the case,
as there is always a global config block

* The breakage-log simply replaces stderr (the old stderr is moved away if needed for errorlog),
and stderr isn't closed after forking.
It defaults to stderr if started with -n (no daemonize), otherwise it defaults to /dev/null.
It is _not_ reopened in log_error_cycle, as there may be many long running childs which have it
still open anyway. Use a pipe-logger with cycle-support if you need it.

- as stderr gets redirected to /dev/null before exec in childs, we cannot
write to the log afterwards, so disabled that log messages too.

i hope it helps with merging stuff back to 1.5
