5 Packages

Packages are listed by definition order.


5.1 http2

HTTP2 API on several levels.

First, it has some high level interface to facilitate making HTTP2 client and
server with some vanilla behaviour. The communication is done mostly by writing to and reading from (Lisp) streams and sending/parsing/receiving headers.

Then, there is an object oriented interface that allows to customize details on
how the client or server acts in some situations. This allows things such as sending pushes on the server side.

Then there is a low level frame oriented interface to read and write frames.

payload-streams.lisp.

Function: read-byte* (stream)
Package

http2/hpack.

Source

utils.lisp.

Function: read-frame (connection &optional stream)

All frames begin with a fixed 9-octet header followed by a variable- length payload.

#+begin_src artist +———————————————–+
| Length (24) | +—————+—————+—————+
| Type (8) | Flags (8) | +-+————-+—————+——————————-+ |R| Stream Identifier (31) | +=+=============================================================+ | Frame Payload (0...) ... +—————————————————————+ #+end_src

Length: The length of the frame payload expressed as an unsigned 24-bit integer. Values greater than 2^14 (16,384) MUST NOT be sent unless the receiver has set a larger value for SETTINGS_MAX_FRAME_SIZE.

The 9 octets of the frame header are not included in this value.

Type: The 8-bit type of the frame. The frame type determines the format and semantics of the frame. Implementations MUST ignore and discard any frame that has a type that is unknown.

Flags: An 8-bit field reserved for boolean flags specific to the frame type.

Flags are assigned semantics specific to the indicated frame type. Flags that have no defined semantics for a particular frame type MUST be ignored and MUST be left unset (0x0) when sending.

R: A reserved 1-bit field. The semantics of this bit are undefined, and the bit MUST remain unset (0x0) when sending and MUST be ignored when receiving.

Stream Identifier: A stream identifier (see Section 5.1.1) expressed as an unsigned 31-bit integer. The value 0x0 is reserved for frames that are associated with the connection as a whole as opposed to an individual stream.

Package

http2.

Source

frames.lisp.

Function: read-http-header (stream context)

Read header field from network stream associated with the CONNECTION.

Note that we can get missing-header-octets on first octet if we have zero length continuation frame.

The END-HEADERS and END-STREAM allow to set the appropriate flags.

Package

http2.

Source

classes.lisp.

Function: update-dynamic-table-size (context new-size)

Update dynamic table for new size that is smaller than the previous one.

Zero size means evict completely; in this case the new vector can be cleaned

Package

http2/hpack.

Source

hpack.lisp.

Function: write-ack-setting-frame (stream)

Write ACK settings frame.

ACK (0x1): When set, bit 0 indicates that this frame acknowledges receipt and application of the peer’s SETTINGS frame. When this bit is set, the payload of the SETTINGS frame MUST be empty. Receipt of a SETTINGS frame with the ACK flag set and a length field value other than 0 MUST be treated as a connection error (Section 5.4.1) of type FRAME_SIZE_ERROR. For more information, see Section 6.5.3 ("Settings Synchronization").

Package

http2.

Source

frames.lisp.

Function: write-altsvc-frame (http-connection-or-stream origin alt-svc-field-value &rest keys &key)

See RFC 7838. The ALTSVC HTTP/2 frame advertises the availability of an alternative service to an HTTP/2 client.

frames.lisp.

Function: write-continuation-frame (http-connection-or-stream headers &rest keys &key end-headers)

#+begin_src artist

+—————————————————————+
| Header Block Fragment (*) ... +—————————————————————+ #+end_src

The CONTINUATION frame (type=0x9) is used to continue a sequence of header block fragments (Section 4.3). Any number of CONTINUATION frames can be sent, as long as the preceding frame is on the same stream and is a HEADERS, PUSH_PROMISE, or CONTINUATION frame without the END_HEADERS flag set.

Package

frames.lisp.

Function: write-data-frame (http-connection-or-stream data &rest keys &key end-stream padded)

#+begin_src artist

+—————+———————————————–+ | Data (*) ... +—————————————————————+ #+end_src

DATA frames (type=0x0) convey arbitrary, variable-length sequences of octets associated with a stream. One or more DATA frames are used, for instance, to carry HTTP request or response payloads.

Package

http2.

Source

frames.lisp.

Function: write-frame-header (stream length type flags http-stream r)

All frames begin with a fixed 9-octet header followed by a variable- length payload.

#+begin_src artist +———————————————–+
| Length (24) | +—————+—————+—————+
| Type (8) | Flags (8) | +-+————-+—————+——————————-+ |R| Stream Identifier (31) | +=+=============================================================+ | Frame Payload (0...) ... +—————————————————————+ #+end_src

Length: The length of the frame payload expressed as an unsigned 24-bit integer. Values greater than 2^14 (16,384) MUST NOT be sent unless the receiver has set a larger value for SETTINGS_MAX_FRAME_SIZE.

The 9 octets of the frame header are not included in this value.

Type: The 8-bit type of the frame. The frame type determines the format and semantics of the frame.

Flags: An 8-bit field reserved for boolean flags specific to the frame type.

Flags are assigned semantics specific to the indicated frame type. Flags that have no defined semantics for a particular frame type MUST be ignored and MUST be left unset (0x0) when sending.

R: A reserved 1-bit field. The semantics of this bit are undefined, and the bit MUST remain unset (0x0) when sending and MUST be ignored when receiving.

Stream Identifier: A stream identifier (see Section 5.1.1) expressed as an unsigned 31-bit integer. The value 0x0 is reserved for frames that are associated with the connection as a whole as opposed to an individual stream.

Package

http2.

Source

frames.lisp.

Function: write-goaway-frame (http-connection-or-stream last-stream-id error-code debug-data &rest keys &key reserved)

#+begin_src artist +-+————————————————————-+ |R| Last-Stream-ID (31) | +-+————————————————————-+ | Error Code (32) | +—————————————————————+ | Additional Debug Data (*) | +—————————————————————+ #+end_src

The GOAWAY frame (type=0x7) is used to initiate shutdown of a connection or to signal serious error conditions. GOAWAY allows an endpoint to gracefully stop accepting new streams while still finishing processing of previously established streams. This enables administrative actions, like server maintenance.

Package

http2.

Source

frames.lisp.

Function: write-headers-frame (http-connection-or-stream headers &rest keys &key end-headers end-stream padded priority)

#+begin_src artist

+-+————-+———————————————–+ |E| Stream Dependency? (31) | +-+————-+———————————————–+ | Weight? (8) | +-+————-+———————————————–+ | Header Block Fragment (*) ... +—————————————————————+ #+end_src

The HEADERS frame (type=0x1) is used to open a stream (Section 5.1), and additionally carries a header block fragment. HEADERS frames can be sent on a stream in the "idle", "reserved (local)", "open", or "half-closed (remote)" state.

Package

http2.

Source

frames.lisp.

Function: write-ping-frame (http-connection-or-stream opaque-data &rest keys &key ack)

The PING frame (type=0x6) is a mechanism for measuring a minimal round-trip time from the sender, as well as determining whether an idle connection is still functional. PING frames can be sent from any endpoint.

#+begin_src artist +—————————————————————+ | | | Opaque Data (64) | | | +—————————————————————+ #+end_src

Figure 12: PING Payload Format

In addition to the frame header, PING frames MUST contain 8 octets of opaque data in the payload. A sender can include any value it chooses and use those octets in any fashion.

Receivers of a PING frame that does not include an ACK flag MUST send a PING frame with the ACK flag set in response, with an identical payload. PING responses SHOULD be given higher priority than any other frame.

The PING frame defines the following flags:

ACK (0x1): When set, bit 0 indicates that this PING frame is a PING response. An endpoint MUST set this flag in PING responses. An endpoint MUST NOT respond to PING frames containing this flag.

Package

http2.

Source

frames.lisp.

Function: write-priority-frame (http-connection-or-stream priority &rest keys &key)

The PRIORITY frame (type=0x2) specifies the sender-advised priority of a stream (Section 5.3).

#+begin_src artist +-+————————————————————-+ |E| Stream Dependency (31) | +-+————-+———————————————–+ | Weight (8) |
+-+————-+
#+end_src

The payload of a PRIORITY frame contains the following fields:

E: A single-bit flag indicating that the stream dependency is exclusive (see Section 5.3).

Stream Dependency: A 31-bit stream identifier for the stream that this stream depends on (see Section 5.3).

Weight: An unsigned 8-bit integer representing a priority weight for the stream (see Section 5.3). Add one to the value to obtain a weight between 1 and 256.

Package

http2.

Source

frames.lisp.

Function: write-push-promise-frame (http-connection-or-stream headers promised-stream-id &rest keys &key end-headers padded reserved)

The PUSH_PROMISE frame (type=0x5) is used to notify the peer endpoint in advance of streams the sender intends to initiate. The PUSH_PROMISE frame includes the unsigned 31-bit identifier of the stream the endpoint plans to create along with a set of headers that provide additional context for the stream. Section 8.2 contains a thorough description of the use of PUSH_PROMISE frames.

#+begin_src artist +-+————-+———————————————–+ |R| Promised Stream ID (31) | +-+—————————–+——————————-+ | Header Block Fragment (*) ... +—————————————————————+ #+end_src

The PUSH_PROMISE frame payload has the following fields:

R: A single reserved bit.

Promised Stream ID: An unsigned 31-bit integer that identifies the stream that is reserved by the PUSH_PROMISE. The promised stream identifier MUST be a valid choice for the next stream sent by the sender (see "new stream identifier" in Section 5.1.1).

Header Block Fragment: A header block fragment (Section 4.3) containing request header fields.

The PUSH_PROMISE frame defines the following flags:

END_HEADERS (0x4): When set, bit 2 indicates that this frame contains an entire header block (Section 4.3) and is not followed by any CONTINUATION frames.

A PUSH_PROMISE frame without the END_HEADERS flag set MUST be followed by a CONTINUATION frame for the same stream. A receiver MUST treat the receipt of any other type of frame or a frame on a different stream as a connection error (Section 5.4.1) of type PROTOCOL_ERROR.

Package

http2.

Source

frames.lisp.

Function: write-rst-stream-frame (http-connection-or-stream error-code &rest keys &key)

The RST_STREAM frame (type=0x3) allows for immediate termination of a stream. RST_STREAM is sent to request cancellation of a stream or to indicate that an error condition has occurred.

#+begin_src artist +—————————————————————+ | Error Code (32) | +—————————————————————+ #+end_src

The RST_STREAM frame contains a single unsigned, 32-bit integer identifying the error code (Section 7). The error code indicates why the stream is being terminated.

The RST_STREAM frame does not define any flags.

Package

http2.

Source

frames.lisp.

Function: write-settings-frame (http-connection-or-stream settings &rest keys &key ack)

#+begin_src artist
+——————————-+
| Identifier (16) | +——————————-+——————————-+ | Value (32) | +—————————————————————+ #+end_src

The SETTINGS frame (type=0x4) conveys configuration parameters that affect how endpoints communicate, such as preferences and constraints on peer behavior. The SETTINGS frame is also used to acknowledge the receipt of those parameters. Individually, a SETTINGS parameter can also be referred to as a "setting".

Package

http2.

Source

frames.lisp.

Function: write-window-update-frame (http-connection-or-stream window-size-increment &rest keys &key reserved)

#+begin_src artist +-+————————————————————-+ |R| Window Size Increment (31) | +-+————————————————————-+ #+end_src

The WINDOW_UPDATE frame (type=0x8) is used to implement flow control; see Section 5.2 for an overview. Flow control operates at two levels: on each individual stream and on the entire connection.

Method: initialize-instance :after ((connection client-http2-connection) &key &allow-other-keys)

In HTTP/2, each endpoint is required to send a connection preface as a final confirmation of the protocol in use and to establish the initial settings for the HTTP/2 connection. The client and server each send a different connection preface.

The client connection preface starts with a sequence of 24 octets. This sequence MUST be followed by a SETTINGS frame (Section 6.5), which MAY be empty.

Special Variable: +client-preface-start+

The client connection preface starts with a sequence of 24 octets, which in hex notation is this. That is, the connection preface starts with the string "PRI * HTTP/2.0rnrnSMrnrn").

Package

http2.

Source

classes.lisp.

Special Variable: static-headers-table

Static headers table. Each element is either list of header name and value, or just header name. The content is defined in the RFC7541, and is supposed to start at index 1, so leading nil.

6.2.3 Macros

Macro: check-place-empty-and-set-it (new-value accessor)

All HTTP/2 requests MUST include exactly one valid value for the :method, :scheme, and :path pseudo-header fields, unless it is a CONNECT request (Section 8.3). An HTTP request that omits mandatory pseudo-header fields is malformed (Section 8.1.2.6).

Macro: define-frame-type (type-code frame-type-name documentation (&rest parameters) (&key flags length must-have-stream-in may-have-connection must-have-connection new-stream-state bad-state-error has-reserved) writer (&body reader))

Define:
- A frame type object that allows to read frame of given type,
- a constant named ‘+foo+‘ that translates to TYPE-CODE,
- a writer function WRITE-FOO that takes CONNECTION or HTTP-STREAM and possibly other PARAMETERS and FLAGSs and writes appropriate frame.

Each PARAMETER is a list of name, size in bits or type specifier and documentation.

Package

Function: check-stream-state-ok (connection http-stream ok-states bad-state-error)

Throw BAD-STATE-ERROR when the stream state is not appropriate for the frame type.

Return the HTTP-STREAM.

Package

http2.

Source

frames.lisp.

Function: close-http2-stream (stream)

Close the http2 stream.

It marks the stream as closed, which is maybe unnecessary, as the stream is immediately removed from the list of streams of its connection. This is consistent with the concept that any stream not in the connection streams explicitly is either idle (if above last-id-seen or id-to-use, depending on even/odd) or closed - see FIND-HTTP-STREAM-BY-ID.

The removal of unused streams is necessary to prevent leakage for big requests - other solution would be to send go-away after the number of streams is too high; however some clients (e.g., h2load) do not retry when they receive this.

This stream removal should be done with lock on the appropriate stream when in multiple threads. When this is called from the read-frame callbacks it is done automatically, otherwise caller must ensure it.

6.2.7 Structures

Structure: frame-type

Description of a frame type.

Apart from name and documentation, each frame type keeps this:
- RECEIVE-FN :: How to handle reading of received frames
- NEW-STREAM-STATE :: whether it can be used to create new streams (i.e., is allowed on streams in IDLE state) and if so what is new state of such stream
- OLD-STREAM-OK :: in what stream states the frame can be received
- CONNECTION-OK :: whether the frame can have STREAM-ID equal to zero, that is, act on connections.
