Re: [twsocket] How to install V8?

 I have V8 Beta installed, but how to install the Firemonkey version?
 
 Seems like I need to install the CommonXE4Design   but I cannot
 install that one.
 Unless I am missing something here
 I am able to compile the XE4Run project.

At first remove the VCL-only design-time package from the IDE if any
(Component | Install Packages).

Open DXe4InstallVclFmx.groupproj located in the Ics\Install folder.
In the project manager make sure that the Windows 32 target platform is
selected for each of the three run-time packages. Activate IcsCommonDXE4Run
and from the context menu select From Here.. | Build All From Here

Repeat this for all three platforms.

Finally install the three design-time packages in the order they appear
in program manager. Set the library path to the dcu output directory.
For instance: $(ICSRoot)\lib\$(Config)\$(Platform)\XE4,
where $(ICSRoot) is a custom environment variable set to ICS' root
directory.

Re: [twsocket] ICS Stable for 64bits?

2013-05-17 Thread Arno Garrels
On Thursday, May 16, 2013 11:05 PM [GMT+1=CET],
Eric Fleming Bonilha schrob:

 Hello!
 
 I would like to know if ICS is already stable for 64bits development.

I'm pretty sure it is. Try the the demos including SSL/TLS they do work.


 I`m porting my system to 64bits and I updated to ICS8, but I´m having
 many issues (ICS is in the core of my system) that looks like memory
 overflow or overwrite, so, I´m trying to find out the problems and I
 want to eliminate the possibility of errors on 3th party libraries

At first read this: 
http://docwiki.embarcadero.com/RADStudio/XE4/en/Converting_32-bit_Delphi_Applications_to_64-bit_Windows

From my own experience, the old Win-API header translations are often
the problem, from wrong declarations of the functions to wrong record
field alignment.

Note: The 64-bit compiler is actually quite usable, however the
64-bit debugger is still very buggy.

 The Finalization
 section calls DeleteCriticalSection(SslCritSect).
 TComponent.DestroyComponent calls the destructor of all its

 method uses EnterCriticalSection(SslCritSect) and
 LeaveCriticalSection(SslCritSect), which causes an access violation
 and prevents the app from closing. 

Do you use multiple threads with ICS?
If so, make sure all threads are closed before the application
exits.

Indeed, most likely.

 What does

It is main thread's message loop.

 specifically cleaning up, that could be missing?

When main thread's message loop quits the application

 Thanks for the quick and helpful response!

You are welcome, in ICSv8 we want to support IPv6 that requires
the winsock2 API. EMBT's Winsock.pas just supports old winsock1 
and even the newer Winapi.Winsock2.pas doesn't support IPv6, so
we had to write our own custom header translation named
OverbyteIcsWinsock.pas. In ICSv8 applications you should replace
any occurence of winsock.pas with OverbyteIcsWinsock.pas.

When I try to Post some nonsense data to your URL it

to initiate a SSL/TLS renegotiation so there are two  
OnSslHandshakeDone events for me.
 
The first handshake in _your log succeeds however the second fails:

{code}

Maybe a newer OpenSSL libraries will help since some older versions
did not support renegotiation due to some security issue that was 
fixed in newer versions. In my test above I used Openssl v0.9.8x 
32-bits from: http://wiki.overbyte.be/wiki/index.php/ICS_Download
with latest ICSv8, latest ICSv7 should make no difference in this

From what you posted in your previous mail there's no SSL stuff included
in the log, check your IcsLogger LogOptions. Best results when you include
every LogOption except just one of the loDest.. opts, choose loDestFile
and LogFileOption = lfoOverwrite. That's the fastest way to get it all
logged. If you send that file to me as PM I'll take a look at it when
I have some minutes, either today or tomorrow evening.

 Now I am incorporating the code into another project, and I would

 know who else the message is being sent to. 
 
 Is Blind carbon copy possible with this component?

Of course it is. The easiest way is to use method 
RcptNameAdd(const ToList, CcList, BccList: string) as shown
in MailSnd demo in order to specify the recipients.
List separator is either ; or ,.
A Bcc recipient simply isn't listed in the email header.
Means do neither assign Bcc recipients to property HdrTo nor
to HdrCc.

 likely to be a server issue? 

I don't know what the problem is, the only way to know is to try to 
reproduce the reported problem. 
Do your users connect thru a proxy with HTTP authentication and if yes,
what type of proxy authentication? There are AFAIK some old proxies 
that require HTTP/1.0. What type of authentication is provided and 
actually used for the protected page? Is HTTPS the proto?  

 Some users are reporting that the
 authentication doesn't work in my recent releases, which default to
 HTTP/1.1 now instead of HTTP/1.0. 

Maybe it is due to my latest, just briefly tested, bugfix? Though I
don't think so.

This is definately not the way to use ICS components.
Either use the events or, if available, the synchronous methods.

Of course, never call sleep() (at least in 99.99% of the casses) since

Yes it is, provided that port 26 isn't blocked and the SMTP server is

 Hi,
 I'm using an API to send files to a VOD platform through the

 My problem is that my connection is closed by the server due to a

 The server seems not responding to my GET request before he has
 finished to download the file from my web server. So when the
 filesize is bigger than 2MB the timeout is raised.  
 
 Does the probleme can come from settings in the TSslHttpCli ?

I don't think so, since you use async methods there's no client-side
timeout by default.

 Can I desactivate any connection timeout (I used
 SslHttpCli.Connection := 'Keep-Alive';) ? 

With HTTP v1.1 Keep-Alive is the default, it just *asks* the 
server to keep the connection alive, however most servers close
connections after a short idle period nevertheless which is legal.

I do not see the logging is wrong, actually it's logged

 It should redirect to:

I tested with current ICSv8/v7 and it works perfectly (checked with Wireshark).
The only problem is that property Location doesn't include the non-default

 But THttpCli seems to ignore the port 

No it doesn't with a recent ICS, only property Location is a bit buggy IMO.

 You will see RequestDone is triggered twice, and external exception

If you want MadExcept handle those exceptions add i.e. these lines
 
initialization
  SetIcsThreadLocalFinalBgExceptionHandling(fehAppHandleException);

This tells ICS to call the global Application's exception handler
for any unhandled background exception in main thread context rather 
than eat unhandled exceptions. 

 I know I can solve this by using try/except on the final code, or
 using BgException (canclose := False),

Indeed it's best practice to catch and handle all exceptions in the
event handlers. 

 but why is this happening?

It happens because Abort is called by default on unhandled exceptions
which in turn calls OnRequestDone() again.

 Hello
 
Using either MagFTP or the ICS FTP Client how can I determine
 if a File Exists on an FTP Server? 
 
 I do not want to download it, just check if it exists.
 

Method Ls is what you are looking for.

 It would appear that this FTP site does not send a FTP 226 Transfer
 Complete for large files. 
 
 So it's a faulty FTP server, not a problem with the FTP client.

Or only that server is behind a router or it is the slowest. I still think
it's likely a faulty router that times out the control connection, hence the
FTP 226 Transfer Complete response is very likely sent however dropped by
the router, so not logged in Wireshark.

received. From how I read OP's messages the response to the PUT request
is sometimes and sometimes not included in the Wireshark logs, which is

 I have an odd effect that I'm sure one of you clever guys will

 I am using the FTP client to put a file on the a web site. The file

 files to/from the hard drive.
 Apart from the first 4 bytes in the file, the data is stored as
 Unicode. So in the case of English text every other byte is zero. Now
 when I putAsync the file and look at the result it has stored every
 carriage return with the two bytes in reverse order. So $0D, $00 is
 stored as $00, $0D. Line feeds and all the other text are stored
 correctly. 
 
 Am I doing something wrong? The FTP component is as per the default
 settings.

Note, that if you call Connect with a host name TWSocket performs a 
blocking DNS lookup that cannot be canceled. Such blocking DNS lookup
also prevents the timeout timer from working. In order to be able to
cancel the DNS lookup request one has to use nonblocking method DnsLookup
first and call Connect with an IP address. The TimeoutConnect works
for Connect calls with IP address only, so it's a bit useless.

That is normal behaviour. After a Connect two select messages are received from

Then after a Send DataSent triggers again.

 Because the program is ending when the leak occurs that is exactly

 So, after I close all the clients, I call now server.ProcessMessages
 and that seems to handle the leak.
 
 Do you see any problem with that solution?

Don't know, generaly I try to avoid calling the message pump,
in case of destroying the TWSocketServer object it's better to abort all
clients, have you tried method DisconnectAll already?

The leak happens when the call to PostMessage() succeeds however

Re: [twsocket] Shutdown without OnClientDisconnect

Josh Leder wrote:
 Hello
 
 I'm using ICS v7 as a SOCKS4 server. I've got a TWSocketServer
 component that accepts clients, and performs beautifully in most
 circumstances. The issue I'm having is that often an HTTP client will
 send its request and then perform a shutdown(SD_SEND), waiting to
 receive response data from the HTTP server which will then perform
 its own shutdown(SD_SEND). 
 
 The TWSocketServer seems to process this as an OnClientDisconnect
 event, while the TWSocketClient class just performs an
 OnDataAvailable, and Client.Receive returns 0 which is the standard
 behaviour to indicate a shutdown(SD_SEND) event from the SOCKS peer.
 
 Is there any way to prevent the Server.OnClientDisconnect in this
 case? 

Yes, I think so.

 I'd like to pass the shutdown(SD_SEND) to the remote (proxied)
 host and maintain the TWSocketClient connection open until both sides
 have closed the connection normally.

You could override procedure TCustomWSocket.Do_FD_CLOSE(var msg: TMessage); 
in your custom TWSocketClient class in order to delay the shutdown.
However make sure that you call TriggerSessionClosed() (later on) otherwise
TWSocketClient objects would leak.

Re: [twsocket] Timeout during 'put' with TFtpClient

 I have an application which uploads a small file every 10 seconds
 using a TFtpClient. I have the timeout set to 15 seconds. One
 installation is getting a timeout every couple of minutes:

The server does not seem to close the data connection after the client
did send Shutdown(1) hence the timeout, that is a server bug IMO.

Re: [twsocket] TSslSmtpCli won't complete TLS on port 25

 That's been the mystery for me, Arno!

Same for me, especially since both port numbers do work for me and 
my customers.

 01:58:30:254 022C2400 BIO_ctrl_get_write_guarantee(nbio) = 4096   [23]
 02:08:29:657 022C2400 TCustomSslWSocket.Do_FD_CLOSE error #0 556

Here's the problem, there's nothing more received but a connection close
after around 10 seconds?

 Hi Arno,
 
 I'm sorry to say, I couldn't run the demo in cbuilder 2007. But I
 put together a quick demo based on the SslMailSnd project to test
 for the problem. It's a very small project _only_ intended to test
 for failed handshake--nothing more.
 
 My demo resulted in the same problem that my program has. It fails
 the handshake. Here are my results.
 
 Make sure that property TSslContext-SslVersionMethod is set to
 sslV23_CLIENT and that you use recent SSL libraries from here (
 supported version depends on the version of your source code):
 http://wiki.overbyte.be/wiki/index.php/ICS_Download
 
 Gee, I had hopes for that! But it still fails the handshake. Just as
 a test I set the port to 587 in my little demo and then the handshake
 succeeded. But on port 25, fails.

If it does work with port 587 it should work with port 25 the same
way since both support the STARTTLS command. 
I've no idea why it doesn't work for you?

 
 If the handshake still fails drop a TIcsLogger onto the form,
 tick all options and log the failure, post the log to this
 list.
 
 Well, I didn't get much:
 
 12:51:02:198 InitCtx OpenSSL version: OpenSSL 1.0.0d 8 Feb 2011
 
 That's it. 

Sorry for my bad advise. The TSslContext has a published property 
IcsLogger, simply assign it in object inspector. Also assign 
TSslSmtpClient-CtrlSocket-IcsLogger the same IcsLogger instance at
runtime.

 This happens regardless of the server.

 I use STARTTLS with smtp.gmail.com on port 25 without any problems,

 It's not clear how you fixed it?
 You should specify UTF-8 as the charset if you convert mail body
 and subject line etc. to UTF-8. Also set Allow8BitChars to FALSE so
 any 8-bit char will be quoted printable encoded.
 
 
 yes I specified UTF-8 as charset and converted body and subject via
 AnsiToUTF8 and that looks good now. I also thing I did set
 Allow8BitChars to FALSE, but out of my head I'm not sure.
 
 For me it looks this will be ok until I completely convert to Unicode.

Very likely, yes. However consider the port to Unicode soon, V7 includes
countless bugfixes, I'm unable to enumerate all fixes here (they are plenty).

Re: [twsocket] SmtpCli and sending mails in international context

2012-08-01 Thread Arno Garrels
Markus Humm wrote:
 Hello,
 
 I used SmtpCli in one of my applications (ok still ICS V5 under D2007)


ICS V7 supports D7+, so unless you have to support Windows 2000- 
you should upgrade ASAP.

 and today I found out that I send all mails with charset set to
 iso8859-1, even when the message body later on contains japanese
 (ANSI). This is of course not well displayed in Outlook on the
 receiving site. Even changing the view/charset doesn't change
 anything for those far eastern languages. For russion setting this to
 russian (windows) does at least change the chars so they're proper
 and result in readable text.

In Ansi Delphi the Charset property must match the message text 
encoding.
In oder to get the current code page call Win API GetAcp() and assign
the matching mime charset name from 
http://www.iana.org/assignments/character-sets.

In V7 if you assign an empty string to property Charset the component
assigns the correct mime charset according to current system Ansi code
page automatically.

 
 Allow8BitChars  is left on it's default value 

This should be turned **off** when you use the MailMessage property
it's just on by default for backward compat.

(remember: I'm still on
 V5, I will move as soon as I get the time to move this project from
 D2007 to something newer).

Again, ICS v7 does support D7+. 
 
 DefaultEncoding is set to smtpEnc7bit

That's OK as long as Allow8BitChars is also set to false at the same
time, since that will automatically encode the strings quoted printable
if required (if any 8-bit chars).   

 
 Any hints for me how to do this the correct way? e.g. find out the
 user's charset and use that? Or sending UTF8? (does this work with all
 mail clients?)

UTF-8 is the charset to use, that should work with all common mail clients
today. In Delphi 2009+ the component automatically converts the 
MailMessage.Text to the Charset specified, in D2007 you have to encode
the mail message text manually.

If your library path points to the ICS\Vc32 directory you have to 
rebuild your project if the output directories are the same for 
32 and 64-bit in order to enforce a .dcu rebuild, a compile won't
be enough.
