Glenn Strauss 7c7f8c467c [multiple] split con, request (very large change)
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

Glenn Strauss fda01e3305 [core] support multiple error logs
e.g. different server.errorlog for different virtual hosts

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)

Glenn Strauss e3dc34d142 [core] array a->sorted[] as ptrs rather than pos
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.

Glenn Strauss a762402da5 [core] keep a->data[] sorted (REVERT)
This reverts commit 2260a8062ee599ecf28d9b52b981603fd2084aff.

original ordering of array elements is significant
e.g. in lighttpd.conf lists where first match to request is applied

Glenn Strauss 83535bbef3 [core] differentiate array_get_* for ro and rw
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)

Glenn Strauss c9f1b612f1 [core] keep a->data[] sorted; remove a->sorted[] 2020-02-24 11:15:32 -05:00
Glenn Strauss b2991c686d [core] perf: array.c performance enhancements
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().

Glenn Strauss a15f40a569 [core] replace open() with fdevent_open_cloexec()
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.

Glenn Strauss f69bd9cdb8 [core] perf: simple, quick buffer_clear()
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)
