This commit is a flag day, your old modules will almost certainly
need to be updated in order to build properly with these changes.
Summary of changes:
- Offload HTTP bodies to disk if they are large (inspired by #100).
(disabled by default)
- The http_argument_get* macros now takes an explicit http_request parameter.
- Kore will now throw 404 errors almost immediately after an HTTP request
has come in instead of waiting until all data has arrived.
API changes:
- http_argument_get* macros now require an explicit http_request parameter.
(no more magic invokations).
- http_generic_404() is gone
- http_populate_arguments() is gone
- http_body_bytes() is gone
- http_body_text() is gone
- http_body_read() has been added
- http_populate_post() has been added
- http_populate_get() has been added
- http_file_read() has been added
- http_file_rewind() has been added
- http_file_lookup() no longer takes name, fname, data and len parameters.
- http_file_lookup() now returns a struct http_file pointer.
- http_populate_multipart_form() no longer takes an secondary parameter.
New configuration options:
- http_body_disk_offload:
Number of bytes after which Kore will offload the HTTP body to
disk instead of retaining it in memory. If 0 this feature is
disabled. (Default: 0)
- http_body_disk_path:
The path where Kore will store temporary HTTP body files.
(this directory does not get created if http_body_disk_offload is 0).
New example:
The upload example has been added, demonstrating how to deal with file
uploads from a multipart form.
Kore pre-allocates a kore_buf for the full size of the
incoming HTTP body ... but also was passing the full
size to the net_recv_reset() function.
Instead of this, properly read smaller chunks from the
network and append them to the body buffer as they roll in.
Allow setting it to 0 which will disable HTTP requests
that have a body (POST/PUT).
Reduce default http_body_max to 1MB by default, 10MB seems large.
Revisit to this code inspired by #100.
Semantics for using pgsql API have changed quite heavily
with this commit. See the examples for more information.
Based on Github issue #95 by PauloMelo (paulo.melo@vintageform.pt)
with several modifications by me.
Setting the handle callback allows your application
to take care of network events for the connection.
Look at the connection state and flags to determine
if read/write is possible and go from there.
See kore_connection_handle() for more details.
* The cli tools must know when building as KORE_NO_HTTP.
* Reshuffle some structs around to avoid forward declarations.
* Move wscbs under !KORE_NO_HTTP as its for websockets.
* Remove unused members from struct connection.
Applications that use the connect callbacks for new connections
must now set the connection state themselves, see nohttp example.
