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().
e.g. different server.errorlog for different virtual hosts
Also, support different server.breakagelog to have separate script
error logs, applicable to mod_cgi and mod_ssi exec.
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)
While slightly more memory use in 64-bit (though same memory use as
prior versions of lighttpd), avoids bouncing through second array
when searching in sorted list. Most use of arrays in lighttpd is to
build a list once, and elements are not removed from the list.
This reverts commit 2260a8062ee599ecf28d9b52b981603fd2084aff.
original ordering of array elements is significant
e.g. in lighttpd.conf lists where first match to request is applied
array_get_element_klen() is now intended for read-only access
array_get_data_unset() is used by config processing for r/w access
array_get_buf_ptr() is used for r/w access to ds->value (string buffer)
mark array_get_index() as hot, rewrite to be pure and return sorted pos
mark routines as pure, as appropriate
mark routines as cold if used only at startup for config processing
mark params const, as appropriate
array_get_buf_ptr() for modifiable value buffer after insert into array
uint32_t used and size members instead of size_t
remove a->unique_ndx member; simply add to end of array for value lists
remove du->is_index_key member; simply check buffer_is_empty(du->key)
array_insert_key_value() used to be a hint that lookup could be skipped,
but the state from array_get_index() is now saved and reused internally,
so the distinction is no longer needed. Use array_set_key_value().
specialized buffer_eq_icase_ssn func replace strncasecmp()
in cases where string lengths are known to be at least as
large as the len being compared case-insensitively
fdevent_open_cloexec() opens files O_BINARY for consistency,
and with O_NONBLOCK, so that the server will not block if the
target file to open is a fifo.
validate UTF-8 in url-decoded paths obtained elsewhere than from request
(burl_normalize(), if enabled with server.http-parseopts, checks url for
overlong encodings of ASCII chars in the HTTP request-line)
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)
