Free pascal java windows 10#
Test with Delphi 2009 and Free Pascal 3.2.0 (Lazarus 2.0.12) on Windows 10 If you want to reproduce it with your version of Delphi (or Free Pascal), you may take a small test project from and configure it to connect with a local or public FTP server. Reportedly the timeout also occurs with Delphi 10.4. It is possible to reproduce the bug not only with Delphi 11 but also with Free Pascal. In the Indy issue tracker, a bug was reported which first appeared with Delphi 11.įTP LIST timeout with latest Delphi 11 (and idFTP) In the next part, we will implement a continuos data stream. This must initially be an implementation-defined value, probably in the region of a few seconds. As specified in the HTML spec for EventSource, the client will retry after some seconds:Įach EventSource object has the following associated with it: When the browser navigates to the server will provide the HTML and the embedded JavaScript will start reading data from the address (and receive only one event). S := TFileStream.Create('index.html', fmOpenRead)

To see the full response of the server to the GET request, you may useĪRequestInfo: TIdHTTPRequestInfo AResponseInfo: TIdHTTPResponseInfo) The client will only retry (reconnect and send a new request), if the the server disconnects its end of the connection, or no data is received and the connection times out.The connection will not be closed after sending one or more events.The length of the response is unknown (it is virtually unlimited), therefore the HTTP response must not contain a content-length header.The server sends a continuous stream of events as response to the HTTP GET request to the /sse resource.When the browser navigates to the server will provide the HTML and the embedded JavaScript will start reading event data from Notable difference from the previous version: Procedure TMySSEServer.DoCommandGet(AContext: TIdContext ĪResponseInfo.ContentType := 'text/event-stream' ĪResponseInfo.CacheControl := 'no-store' Ī(Data) ĪResponseInfo.ContentType := 'text/html' ĪResponseInfo.ContentStream := TFileStream.Create('index.html', fmOpenRead) The clients are tested with a small console application (see below). Note: terminators with three or more bytes are supported by the provided code, but very unusual: every additional byte will slow down the request processing considerably. A notable example is STOMP, which specifies that the content must be terminated with a NULL byte 2.ġ) In UTF-8 encoding, Snowman is the byte sequence 0圎2 0x98 0x83.Ģ) See Stomp Protocol Specification Version 1.2. However, some (text-oriented) protocols use a different terminator. Therefore, some of the TCP socket libraries offer read methods with a configurable line terminator, but limited to these two. Some background: many Internet protocols use carriage return (octet 13) and/or line feed (octet 10) as line terminator. Encoded in UTF-8 it is three bytes long 1. The Unicode Character “☃” (U+2603), named Snowman, is not used in any protocol I am aware of. This is the second part in a series which explores basic TCP socket use cases and presents them in minimal examples.įor this part, I selected an unusual string terminator byte sequence.
