Re: [twsocket] Skype like application
Because your question/topic is much broader than what is usually discussed in these simple mailing lists, mostly used for discussion/issues related to ICS itself rather than asking for extensive help in making an application. At Stack however you'll reach a much larger audience who often post code and lots of related information/related questions to raise their points/etc and it's a much better platform for discussion than this thread of mails.

Re: [twsocket] THttpCli - How to know what URL is requested?
You can use the OnLocationChange event to know when the URL changed. On Thu, Dec 20, 2012 at 4:10 PM, Albert Wiersch supp...@htmlvalidator.comwrote: How can I know what URL was last requested? The URL property seems to always be the original URL, so this doesn't work in the case of a redirection. The Location property seems to indicate the last value of the location property that was received, and is sometimes, but not always the URL of the current request. Is there an easy way to do always know the URL of the current request when redirections are used? Or do I have to use more complicated method than simply accessing a property? I would think this is very important for proper cookie handling, because cookies always need to be based on the current URL (as far as I know anyway).

[twsocket] Modify header before send
Hi, posted this a while ago, Feb 21st, 2011, and it had no response. Thought I'd bring it up again, as maybe I'm missing something and this is possible some other easier way? (though it doesn't seem like from looking at the code, there's nothing to allow custom headers besides the triggered event) Original message: (lines won't match with current version) I made a small modification to OverbyteIcsHttpProt, maybe it can be sorted for the next version. OverbyteIcsHttpProt : I made a small change to modify the headers before sending a request. I know there is an event for it, OnBeforeHeaderSend, however that's not quite handy. Usually you need add something to the header just before the call, so to use the event you would have to set a flag or something that adds the header only in case of certain calls.. like, let's say, you are gonna make a few gets or posts, but only need to modify the header for one of them, it's not really convenient then to use the event if you are using the same socket object for all the calls. Isn't it more handy if you can just modify it before your call? So I changed the following: 589: FExtraSendHeader : String; 914: property ExtraSendHeader : String read FExtraSendHeader write FExtraSendHeader; 2405:// 2011, before TriggerBeforeHeaderSend if FExtraSendHeader '' then begin Headers.Add(FExtraSendHeader); FExtraSendHeader := ''; end; -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

[twsocket] exception after THttpCli.ReqDone causes double trigger of RequestDone
Hi, been experiencing something kinda odd, not sure if this is on purpose
or a bug somewhere:
After RequestDone with THttpCli, if there is an -unhandled- exception
before the code is out of ReqDone stack, RequestDone is triggered again.
Try the following code:
httpcli1.RcvdStream := tmemorystream.Create;
httpcli1.URL := 'google.com';
httpcli1.Get;
procedure TForm1.HttpCli1RequestDone(Sender: TObject; RqType:
THttpRequest; ErrCode: Word);
var ts: tstringlist;
begin
if rqtype httpGET then exit;
memo1.Lines.Add('req done');
ts := tstringlist.Create;
ts.Add('sdfdsf'); // 0
caption := ts[1]; // list out of bounds, 0..1..2
end;
You will see RequestDone is triggered twice, and external exception
handlers or delphi's don't trigger at all (e.g madExcept).
I know I can solve this by using try/except on the final code, or using
BgException (canclose := False), but why is this happening?

Re: [twsocket] deflate for OverbyteIcsHttpCCodZLib
Hmm it may be an issue with the site then; the XML is part of an API used by some applications, I haven't see others have an issue with this however. From my testing: - Using only gzip: the XML is not encoded but ICS think it is, therefore trying to decode non-encoded data, resulting in an error. (tested with my user there, I get uncompressed xml with ~780 KB) - Using gzip, deflate: XML is encoded/compressed, size is around 67 KB On my end, I use this code with Zlib to decode after receiving the data (after Get request finished successfully) // 1 = utf8 failed, defaulted to ansi function LoadTSListFromGzipMS(var ts: TStringList; SrcMS: TStream; useUTF8: Boolean): byte; var ms: TMemoryStream; begin ms := TMemoryStream.Create; SrcMS.Seek(0,0); ZlibEx.ZDecompressStream2(SrcMS,ms,15+32); ms.Position := 0; Result := 0; if useUTF8 then ts.LoadFromStream(ms, TEncoding.UTF8) else ts.LoadFromStream(ms); if useUTF8 and (ts.Count = 0) then begin ms.Position := 0; ts.LoadFromStream(ms); Result := 1; end; ms.Free; end; On Mon, Oct 8, 2012 at 10:50 AM, Angus Robertson - Magenta Systems Ltd an...@magsys.co.uk wrote: Tested with this website http://myanimelist.net/malappinfo.php If I enable content encoding, then the data received isn't compressed unless I add deflate.

Re: [twsocket] TTwitter component
http://dev.twitter.com/pages/auth_overview http://dev.twitter.com/pages/auth_overviewThere's xAuth to skip the PIN step, but requires the twitter user/pass. Also I made a method in my lib to do almost like xAuth, simulating a browser login, catching the cookies and posting the form etc to retrieve the data, but that's prone to fail. I do like the PIN step to be honest, it's only required once and the user will feel more secure not giving their login details.

Re: [twsocket] TTwitter component

As I said, Twitter don't require the PIN, so you can ignore that step. User only need to authorize the application, and forget about the PIN. Instead of using the ShellExecute to open the browser, you can use the TTwitter approach. Start a modal Request Authorization form with a TWebBrowser pointed to that address. This way you can proceed with the RequestAccess after user close that authorization form. Using this idea, another thing you could do to make your component more user friendly, is to execute internally all the authentication steps, the first time they are needed. User will just need to create the component and call the SendTwit method. The callback will be used only to get the success/unsuccess of the send. ill most likely remove this alternate proc in next revision, and add XAuth support instead. With both methods you should use SSL, or you will be passing user and password in plain text. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] TTwitter component
I was actually 'open' for years, but I've been seeing users not able to
launch urls from my apps with that, cause the default browser may not have
defined that command, was still using it in the first versions of twitter
lib. I added the ShellExecute import to avoid adding another unit; I rather
not include entire units for things where I need only a couple procs and
such, it adds up to the exe unnecesarily.
As for webbrowser, hmm, I think I still prefer either the PIN or self-auth
approach, else, how we know the user actually allowed the app, we can't just
blindly assume they'll do and think we are now authorized, so the last PIN
step takes care of that.
I read somewhere about embedding a chromium window in delphi btw, heard
anything? I'm curious to test, gonna check for it. I really still dont like
the twebbrowser at all. But maybe I could have a compiler conditional so the
user can opt for a way or another.
Doesn't GPL allow your code to be included in closed source applications as
well? as long as the code hasnt been modified; unless I understood it all
wrong. Tbh it's the first time in over ~12 years programming Im opening up
to release and share source code, so I never looked much into open source
licenses until just now. Would appreciate some insight about it :)

The WebBrowser control works very well for this simple navigate to a page
task.
If you want to test, just replace your RequestPIN code with the next one.
uses
forms, ShDocVw, Controls;
...
procedure TwitterCli.RequestPIN;
var
AuthForm: TForm;
WebBrowser: TWebBrowser;
begin
AuthForm := TForm.create(application.MainForm);
with AuthForm do
begin
BorderStyle := bsDialog;
Caption := 'Twitter Authorization - Authorize and close this
dialog';
width := screen.width - screen.width div 5;
height := screen.height - screen.height div 5;
Position := poScreenCenter;
end;
WebBrowser := TWebBrowser.Create(authForm);
TWinControl(WebBrowser).Parent := authForm;
WebBrowser.Align := alClient;
WebBrowser.Navigate(RequestPinURL);
authForm.ShowModal;
authForm.free;
end;
Also, if you in the end decide to maintain the ShellExecute, then better
specify the 'Open' verb. Some system may have the default verb defined
differently.
ShellExecute(0, 'open', PChar('
https://twitter.com/oauth/authorize?oauth_token=' + OAuthToken), '', '',
SW_SHOWNORMAL);
And you don't need to declare the ShellExecute import, just use the one
defined in the ShellAPI unit.
---
Why you decided to use the GPL v3?
IMHO, for small , and simple, code projects like this one, better use a
license that can be used in closed code applications, or commercial users
will just grab/mangle the code and don't give you any credit.
If credit is given, they will need to open the code too, and that isn't
going to happen. On the other hand, if license permits closed code, they
have no problem to include the reference.

Re: [twsocket] Why ICS prefers non-blocking sockets?
I much prefer non-blocking. While receiving data from a httpcli f.e or over a slow connection etc, my app keeps running while waiting for data. without having to complicate it all with extra threads for everything.

It is all nice line-by-line inline code. With ICS it uses events to reply to reply codes and non-blocking. But with this you lose - easy to follow code flow. If you really need to make it independent you simply put it in separate thread - both Indy and Synapse have their own way of solving this - Indy has special component for threading sockets and Synapse some kind of function that gets called every once in a while.

I prefer ICS for the control it gives me over everything that's going on, for the non-blocking calls, the performance, the extra stuff, and overall how it works, it's really a great piece of software, I use it in all my applications that required net access. I see Indy for example has components even to manage Cookies, leaving the user with no clue what's going on behind the scenes, I prefer handling that myself.

[twsocket] THttpCli modification request, and gzip fix
Hi, I made a small modification to OverbyteIcsHttpProt and OverbyteIcsHttpCCodZLib, maybe it can be sorted for the next version. OverbyteIcsHttpProt : I made a small change to modify the headers before sending a request. I know there is an event for it, OnBeforeHeaderSend, however that's not quite handy. Usually you need add something to the header just before the call, so to use the event you would have to set a flag or something that adds the header only in case of certain calls.. like, let's say, you are gonna make a few gets or posts, but only need to modify the header for one of them, it's not really convenient then to use the event if you are using the same socket object for all the calls. Isn't it more handy if you can just modify it before your call? So I changed the following: 589: FExtraSendHeader : String; 914: property ExtraSendHeader : String read FExtraSendHeader FExtraSendHeader; 2405:// 2011, before TriggerBeforeHeaderSend if FExtraSendHeader '' then begin Headers.Add(FExtraSendHeader); FExtraSendHeader := ''; end; This way you can do ExtraSendHeader := '..extra stuff', just before a GET or POST, so it will be added to the next request and cleared for further calls. OverbyteIcsHttpCCodZLib: I added deflate because otherwise it wasn't working when I was trying to retrieve a page with content-encoding on. Maybe I was doing something else wrong? This fixed it though: 55: Result := 'gzip, deflate'; I found something about this in the archives, someone sent in a modification to support deflate, but it still didn't work for me. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

[twsocket] Modifying headers before send in httpcli fails
Hi, I've been working on Twitter's OAuth implementation, for which I'm using THttpCli. There are various ways to do this, one of which is adding some Auth data in the http headers and not including the parameters int he GET call. However, there's no option in httpcli to manually modify the headers before a request, so I did a tiny modification on OverbyteIcsHttpProt as follows: 587: THttpCli = class(TIcsWndControl) protected FExtraSendHeader : String; 913: published property ExtraSendHeader : Stringread FExtraSendHeader write FExtraSendHeader; 2406: if FExtraSendHeader '' then begin Headers.Add(FExtraSendHeader); FExtraSendHeader := ''; end; I tested this with an event, which seems to be set properly: procedure TForm1.UpdatesSocketBeforeHeaderSend(Sender: TObject; const Method: string; Headers: TStrings); begin memo1.lines.Add(Headers.Text); end; so I fire my Get, and the headers all look correct: URL = http://api.twitter.com/oauth/request_token GET /oauth/request_token HTTP/1.0 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* User-Agent: Mozilla/4.0 (compatible; ICS) Host: api.twitter.com Authorization: OAuth oauth_callback=oob, realm=, oauth_nonce=5B2407849960FC2B4EC23007EA63E8ED, oauth_timestamp=1297549627, oauth_consumer_key=5BZYtiAzGvQTL0ZEhAn45w, oauth_signature_method=HMAC-SHA1, oauth_version=1.0, oauth_signature=RjpaedDdvs6n9yX1TFI%2FNzrnbcQ%3D However, this always fails with Failed to validate oauth signature and token. I made sure the data is 100% correct. If I use the parameters in the URL instead, it works just fine, so they are correct. Any ideas? anywhere else in the code where the added headers might not be going through?

Re: [twsocket] Modifying headers before send in httpcli fails
Oh yeah, dunno why I thought that was read only same effect anyway, the output headers are the same and still OAuth fails. Maybe something to do with the way httpcli sends the headers?

If you call Abort, OnRequestdone will be triggered.
You can set a flag when you call abort, and then you can take action in
OnRequestdone.
You problably have to free some streams anyway, which are usually freed in

Re: [twsocket] UDP question...
I think with UDP you get can get packets in different order, not get them at all, get them repeated.. but as opposed to TCP you get entire packets, if you send 100 bytes at once, you get 100 at once. Someone correct me if I'm wrong.. Hi, This is the first time I am writing a UDP server. The other UDP was a client. It was fairly straight forward. As the server lets say I have 2 clients, A and B, that will be sending me unsolicited data of 100 bytes per message. If I understand, when TWSocket.OnDataAvailable fires the data source can be mixed. For example I could get 10 bytes from A, then 19 bytes from B, then 14 bytes from B and then 56 bytes from A, etc. And I might not get the hundred bytes. I might only get 45. This lead to keeping separate state machines for each client. With TCP I normally read the data to the client buffer and post a message so that OnDataAvailable is as short as possible. In this case it appears I need to read it to a buffer, determine the client, move the data to the clients buffer and post a message. Sound about right?

Re: [twsocket] Delphi2007,UDP, 2x packets
Yeah, I've worked a lot with TCP and it was really no problem requesting a next packet after each, it was very fast. UDP offers some other valuable features though. How do you manage missed/double/wrong ordered packets? I thought of making a buffer to store a certain amount of packets.. say... maybe 100, and have a thread analyze the buffer and request any missing packets until all are complete, then process the data. However requests for missing packets might also be lost.. so shrug, what a pita to work with UDP :p -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Hi, I checked it out, that's quite confusing heh. I'd appreciate it if you could show me a simple code for a UDP wsocket to Listen; and send data back to the host it received from.

Re: [twsocket] Delphi2007,UDP, 2x packets
Thanks, that's really helpful!

[twsocket] Sever architecture
This is less of a socket question and more of an implementation question. Imagine a server with many concurrent connections but that only allows one connection at a time to submit a request, access/manipulate data and then send the results back to all other connections. In other words all requests (regardless of which connection it's coming from) must be serialized. Is the proper architecture to have one thread contain all the connections and then, when an socket event fires, assign the request to a worker thread (from a pool) which in turn attempts to access a critical section of another thread (the data manipulation thread)? Thanks for the input. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Twsocketserver
You could use a custom small header on every packet you send, i.e. first 2-4 bytes being the packet size, so when you receive data you add to a buffer and check if it reached the total size of the packet. If it has not, do nothing, if it has, complete the buffer and send the data packet to a processing routine. If the last data amount received exceeds the packet lenght you specified in the header, you can cut it and move it into a new clean buffer. I have some sources for that if you need - Original Message - From: Igor Pokorny [EMAIL PROTECTED] To: twsocket@elists.org Sent: Monday, August 15, 2005 00:50 Subject: [twsocket] Twsocketserver Hi guys, I do have a realtime application communicates to one side by USB and to the other acts as http server and/or TCPserver.

Re: [twsocket] FTP as system service: Cannot convert port 'ftp-data'
You are right. I tried to run the ftp server demo as a normal app and it failed to resolve ftp port. Something happened in the last few days since it was working earlier. I am quite sure I haven't been infected by a virus though, I keep a good security profile on my system. I don't have norton, don't like it either. As for an antivirus I use Kaspersky. How could I debug this problem to find where the error lies in the system ? Maybe some registry setting ?
