(expansion of buffer_string_lenth() inline function and CONST_BUF_LEN()
macro, which always check for NULL, appears to cause the analyzer to
believe that a pointer might be NULL in cases where it otherwise can
not be NULL)
stream request body using HTTP/1.1 Transfer-Encoding: chunked
(Note: if backend proxy target does not support HTTP/1.1,
then do not use server.stream-request-body = 1 or 2)
If not streaming to backend, collect request body
(now supporting Transfer-Encoding: chunked from client
and then sending with Content-Length to backend)
"Lighty returns HTTP 411 Length Required with proxy and streaming requests/reponses body"
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
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)
reduce initial buffer size if large POST to backend stored in temp files
regression in lighttpd 1.4.52
"[regression] lighttpd gets killed after uploading a big file"
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)
