Glenn Strauss dbdab5dbc9 [core] server.error-handler new directive for error pages (fixes #2702)
server.error-handler preserves HTTP status error code when error page
is static, and allows dynamic handlers to change HTTP status code
when error page is provided by dynamic handler.  server.error-handler
intercepts all HTTP status codes >= 400 except when the content is
generated by a dynamic handler (cgi, ssi, fastcgi, scgi, proxy, lua).
The request method is unconditionally changed to GET for the request
to service the error handler, and the original request method is
later restored (for logging purposes).  request body from the
original request, if present, is discarded.

server.error-handler is somewhat similar to server.error-handler-404,
but server.error-handler-404 is now deprecated, intercepts only 404
and 403 HTTP status codes, and returns 200 OK for static error pages,
a source of confusion for some admins.  On the other hand, the new
server.error-handler, when set, will intercept all HTTP status error
codes >= 400.  server.error-handler takes precedence over
server.error-handler-404 when both are set.

NOTE: a major difference between server.error-handler and the
now-deprecated server.error-handler-404 is that the values of the
non-standard CGI environment variables REQUEST_URI and REDIRECT_URI
have been swapped.  Since REDIRECT_STATUS is the original HTTP
status code, REDIRECT_URI is now the original request, and REQUEST_URI
is the current request (e.g. the URI/URL to the error handler).
The prior behavior -- which reversed REQUEST_URI and REDIRECT_URI values
from those described above -- is preserved for server.error-handler-404.

Additionally, REDIRECT_STATUS is now available to mod_magnet, which
continues to have access to request.uri and request.orig_uri.

handlers for PHP compiled with --force-redirect.  Set to "200"
if (0 == con->error_handler_saved_status)

FYI: setting REDIRECT_STATUS in con->environment allows access and

Glenn Strauss 2f21aaa973 handlers can read response before sending req body (fixes #131, #2566)
dynamic handlers mod_fastcgi, mod_scgi, and mod_proxy can now read
response from backend prior to finishing sending request body.

If the backend closes the connections (or shuts down socket write
end so that lighttpd read() 0 to indicate EOF), then lighttpd will
abort attempting to send request body to backend.

Glenn Strauss 4b0c822ed0 always poll for client POLLHUP/POLLERR events (fixes #399)
to detect client disconnect.  Do so even when waiting on backend,
and not polling for POLLRD or POLLWR on client connection.

This reduces unnecessary load on backends when backends are slow
to respond and client has given up waiting.

the main logic to handle_subrequest hook, where the main logic is
for other dynamic handlers.

Glenn Strauss c263bc6a11 defer reading request body until handle subrequest (fixes #2541)
read request body right before calling subrequest handler,
allowing request to be handled prior to reading request body,
e.g. to send 401 Unauthorized response when authentication is required

(In the future, this might move into each dynamic handler which supports
 request body (mod_cgi, mod_fastcgi, mod_proxy, mod_scgi, mod_webdav) so
 that each dynamic handler can choose whether or not to buffer request
 body or to stream request body to backend as request body is received.)

Glenn Strauss bbbbfb3de0 untangle overly complex control flow logic
for dynamic handlers mod_cgi, mod_fastcgi, mod_scgi, mod_proxy
(mod_cgi control flow logic simplification began in a prior commit)

- connection state machine calls the subrequest handler
- subrequest handler sets up the connection to the backend
  and registers fdevent handler to handle backend events
- fdevent handler handles backend events and then schedules
  a call to connection state machine
- when retrying an alternate backend, backend state is reset
  and then response state is reset so that the connection state
  machine will call back into the subrequest handler to retry

Dynamic handlers no longer directly modify connection state
(calls to connection_set_state() from dynamic handlers were removed)

Dynamic handlers no longer reset con->physical.path, and they
preserve con->mode when retrying alternate backends.  This is done
to skip repeated processing in response.c:http_response_prepare()

While this patch increases consistency in control flow handling,
there is more work to be done that can further improve upon this.

Kyle J. McKay b0ecb4d44b [mod_fastcgi/mod_scgi] zero sockaddr structs before use (fixes #2691)
When a sockaddr_un, sockaddr_in or sockaddr_in6 structure
is allocated on the stack or heap, it may contain random
byte values.

The "unused" and "reserved" parts must be zerod otherwise
unexpected failures may occur.  The simplest way to do
this and be compatible with various platforms' struct
layouts is just to memset them to 0.

Stefan Bühler ad3e93ea96 Use buffer API to read and modify "used" member
- 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.

Stefan Bühler 1be163b44a Remove chunkqueue_get_{append,prepend}* API
Although those were "easy" to use, they violated the abstraction:
  content of the chunkqueue should only be modified via the API.
  Replace with chunkqueue_get_memory() and chunkqueue_use_memory() for
  functions that read data from network (reusing large buffers),
  chunkqueue_steal_with_tempfiles() to store request bodies on disk
  temporarily.
  Modules that were generating content and need a buffer maintain the
  buffer manually (have to be careful to free the buffer on errors, as
  it isn't part of the chunkqueue yet).

Stefan Bühler 6afad87d2e fix buffer, chunk and http_chunk API
* 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.

 * http_auth/ldap: passing uninitialized "ret" to ldap_err2string
 * sizeof(T) not matching the target pointer in malloc/calloc calls;

   * 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);

Stefan Bühler 05858f6cf2 [ssl] Fix $HTTP["scheme"] conditional, could be "http" for ssl connections if the ssl $SERVER["socket"] conditional was nested (fixes #2501)
con->conf.is_ssl got removed and replaced by:
 * con->conf.ssl_enabled for the config var "ssl.engine" - it is only
   used to determine which server-sockets should use ssl. (usually not
   needed as it is mandatory and enough to set ssl.pemfile anyway)
 * con->srv_socket->is_ssl to detect the actual ssl status of the
   bound socket, which is the same as the ssl status of the connection
 * con->uri.scheme for the actual $HTTP["scheme"] value, also used for
   the CGI "HTTPS=ON" variable. This defaults to "https" if the
   connection uses ssl, but can be changed for example by mod_extforward
   if X-Forwarded-Proto: is set to either "http" or "https" (other values
   are ignored right now)

Also removed the broken srv_socket->is_proxy_ssl as it was a connection
value in a server_socket struct...

Stefan Bühler fbdb305f8a Add server.breakagelog, a "special" stderr (fixes #1863)
* 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.
