Re: Email via IMAP with HTML body from a template

[Charles Warwick via use-livecode]

Sorry, the last line of the replacement code should have been:

put mimeEncodeAsMIMEMultipartDocument(tContent, “alernative”) into tBody

(It was missing the "into tBody" at the end of the line)

Re: Email via IMAP with HTML body from a template

[Charles Warwick via use-livecode]

Hi Sean,

After reading your second e-mail, I see that you don't want to use 
mimeEncodeFieldAsMIMEMultipartDocument to generate the HTML version of the 
e-mail body from a field as it does in that sample stack.

If you want to create your own HTML and plain text versions of the e-mail body, 
you can still use that sample stack.  Simply replace the following line:

put mimeEncodeFieldAsMIMEMultipartDocument(the long id of field 
"email_message") into tBody

With something like this:

put “Content-Type: text/plain; charset=UTF-8” & crlf into tHeadersPlain
put “Content-Transfer-Encoding: quoted-printable” after tHeadersPlain
put “” into tBodyPlain
put tHeadersPlain & crlf & crlf & \
mimeEncodeForMIMETransfer(tBodyPlain, “quoted-printable”) into tContent[1]

put “Content-Type: text/html; charset=UTF-8” & crlf into tHeadersHTML
put “Content-Transfer-Encoding: quoted-printable” after tHeadersHTML
put “” into tBodyHTML
put tHeadersHTML & crlf & crlf & \
mimeEncodeForMIMETransfer(tBodyHTML, “quoted-printable”) into tContent[2]

put mimeEncodeAsMIMEMultipartDocument(tContent, “alernative”)

Hope that helps,

Regards,

Charles

Re: Previous request not completed

[Charles Warwick via use-livecode]

Hi Jacque,

You can use tsNet without libURL by using tsNet functions (tsNetGet, tsNetPost, 
...) rather than the libURL syntax (get URL, put URL, ...).

tsNet includes a libURL wrapper so that if you choose to use libURL commands 
and tsNet is included then libURL will perform the requests using tsNet instead 
of its own internal methods.  However, you are also free to not include libURL 
and just use tsNet by itself.

Whether you are using tsNet or libUrl, you can get the "previous request not 
completed" error if you are not using pro features and you are performing 
synchronous transfers.  The "non-pro" version of tsNet acts the same as libURL 
by only allowing one synchronous request at a time (the pro version of tsNet 
allows multiple synchronous requests at the same time).

In order to fix this, you can use tsNet's asynchronous commands (e.g.  tsNetGet 
instead of tsNetGetSync, tsNetPost instead of tsNetPostSync, ...) or libURL's 
"load URL" command.  The "load URL" command only support HTTP GET requests 
which means that if you need to use other types of requests (e.g. POST) then 
use the tsNet functions directly.

The tsNetLibUrlReuseConnection command is used to control whether or not your 
application will try to re-use an open connection to perform another request 
against the same server or whether it will open a completely new connection 
each time.  You will still experience the "previous request not completed" if 
you try to make two synchronous requests against the same server at the same 
time regardless of this setting.

Hope that helps,

Charles

Re: "tsnet (1) Received HTTP/0.9 when not allowed"?

[Charles Warwick via use-livecode]

Hi Richard,

The curl version that is used in tsNet is regularly updated.  The latest 
version of tsNet is using curl 7.74.0.

My understanding of that particular issue is that if the first data line that 
is received back from the HTTP server doesn't match an appropriate response, it 
will assume HTTP/0.9.

Is there a test URL you can post that shows this problem so I can see what is 
coming back from the server?  Can you post what you are getting in the libURL 
debug?

Also, have you tried a version of LC that has a different version of tsNet 
included - just in case this happens to be a new bug in the curl library.

Thanks,

Charles

Re: tsNet mail message too slow!

[Charles Warwick via use-livecode]

Hi Rick,

What platform are you running LC server on?

There is an outstanding issue with tsNet running correctly in LC server on 
certain platforms.  The command executes quickly, but it doesn’t return control 
to the LC script for quite some time.

If this is what you are coming up against, I can have another look to see if 
there is something we can do about it.

Charles

Re: tsNet mail message not formatting

[Charles Warwick via use-livecode]

Hi Rick,

What code did you try to add the Bcc e-mail recipients?

The tRecipient variable to the tsNetSmtpSync command needs to be one e-mail 
address per line of all the recipients for the e-mail (To, Cc and Bcc) and that 
is what is used to determine who the e-mail is sent to.

The rest of that script (in the lesson) is about how to format the e-mail 
message, Bcc addresses don't get added to the header of the e-mail message.

So assuming your Bcc's addresses are stored in a variable called tBcc (one per 
line), then you need to simply adjust the script (from the lesson) as follows:

-- Make tRecipient a list of all recipients (To, Cc and Bcc)
put tTo & cr & tCc & cr & tBcc into tRecipient 

put tsNetSmtpSync(tUrl, tFrom, tRecipient, tEmailMessage, tResponseHeaders, 
tBytes, tSettings) into tResult

Regards,

Charles

Re: tsNet mail message not formatting

[Charles Warwick via use-livecode]

Hi Matthias,

I would not recommend sending e-mail this way.  It will create a new SMTP 
connection and send the e-mail message separately for every single recipient.

SMTP connections (and tsNetSMTP* commands) are designed to handle multiple 
recipients for one e-mail within a single SMTP transfer.

Charles

Re: Version 1.2 of the mail stack

[Charles Warwick via use-livecode]

Hi Rick,

Assuming you are using the code from the lesson, just add any Bcc e-mail 
addresses to the tRecipient variable before the call to tsNetSmtpSync.

Since you don't include them in the variables passed to mimeEncodeAsMIMEEmail, 
the addresses won't be included in the e-mail headers.

Charles

Re: tsNet FTP help

[Charles Warwick via use-livecode]

Hi Scott,

This part of the server response is your clue:

> 421-Sorry, cleartext sessions and weak ciphers are not accepted on this 
> server.
> 421 Please reconnect using TLS security mechanisms.

You need to connect to the FTP server using SSL.  The following LC lesson 
should help:

Re: SSL Error - question from Stack Overflow

[Charles Warwick via use-livecode]

This seems to be an issue which has come up a few times over the years with 
the curl library.

It appears to be specific to when curl is compiled on OS X to use the Mac SSL 
library, rather than OpenSSL.

I am guessing you are trying this on a Mac?

I have tested a build of tsNet under OS X that uses OpenSSL instead, and the 
issue goes away.  Unfortunately, building tsNet to use OpenSSL on Mac would 
mean that it no longer uses the OS X certificate store for verifying SSL 
certificates.

Charles

Re: Which of the current FTP legends should I be using?

[Charles Warwick via use-livecode]

Hi,

If you are following the code from the lesson, what are you getting back in the 
tRecvHeaders variable?  Generally as part of the response stored in that 
variable, it will indicate whether it is using ascii or binary mode for 
transmission.

Re: LibURL and TSNet in LC Indy

[Charles Warwick via use-livecode]

Hi Tom,

Using unique URLs for multiple load URL requests against the same server with 
the standard libUrl library allows you to *initiate* multiple requests at once, 
but the requests will still only be sent to the server one at a time in the 
background.

tsNet will send the requests to the server in parallel, which can significantly 
decrease the time taken to perform the requests (assuming the server can cope 
with the load).

If you want to see what I mean, download the following stack:

https://downloads.techstrategies.com.au/tsNet/tsNet_libUrl_loadUrl.livecode

Open this up in LC Indy edition, and click the “Get Foreign Exchange Rates” 
button several times to get an average total time.

Then disable tsNet by running the following command in a message box:

dispatch “revunloadlibrary” to stack “tsnetliburl”

Then click the button several more times and compare the time difference.

Regards,

Charles

Re: LibURL and TSNet in LC Indy

[Charles Warwick via use-livecode]

Hi Tom,

If you want to stress test an API using the tsNet library, try adding a:

tsNetLibUrlReuseConnection false

Before issuing the loadUrl commands to see if that makes any difference.

Also note that with tsNet, multiple load URL commands can occur at the same 
time against a single server, where as without tsNet, I think that  libUrl will 
wait for one to complete before sending the next one.

So it is also possible that you are hitting the remote server harder when you 
are using tsNet than with the standard libUrl.

Regards,

Charles

Re: tsnetGetFile() example using HTTP?

You can use the same command with HTTP, just make sure you set any HTTP headers 
accordingly (similar to tsNetGet).

As for the issues with FTP, which version of LC are you using?

Hi Phil,

Does this lesson help you?

http://lessons.livecode.com/m/4071/l/853715-how-to-asynchronously-download-via-sftp-directly-to-a-file

It uses SFTP with tsNetGetFile, so while the protocol used is different, the 
concept is the same.

Re: SSH and SCP in LiveCode

[Charles Warwick via use-livecode]

Hi Mike,

tsNet does support file transfers via SSH, just use sftp:// at the start of the 
URL instead of ftp:// or ftps://, otherwise the commands are mostly identical.

Just note that not all SSH features are supported in the Indy version of LC - 
some require the Business edition.

What are you trying to do that you think tsNet doesn’t support?

Regards,

Charles

Re: DELETE url

[Charles Warwick via use-livecode]

Hi,

You can send a HTTP DELETE using tsNet.  There is a lesson here that shows you 
how:

http://lessons.livecode.com/m/4071/l/856543-how-to-send-a-custom-http-request-using-the-tsnet-external

All tsNet functions work on mobile, so no issue there either.

Regards,

Charles

Re: IMAP library, or support via tsNet?

Hi Ben,

Support for IMAP was added into tsNet a while ago. There are a few lessons that 
I’ve added to LiveCode’s website on IMAP.

Re: Websockets Problem on LiveCode

[Charles Warwick via use-livecode]

Hi Todd,

Did you try the sample LC stack that I sent you with the socket external?  It 
allows you to send basic websocket messages to a server.  If you did try it, 
what happened?

The beta version should work on Windows, Mac and iOS (Android version is easy 
to add if needed).

Regards,

Charles

Re: Example of Livecode function settings array syntax?

[Charles Warwick via use-livecode]

Hi Keith,

If you take a look at the following LC lesson for uploading a file via FTP with 
tsNet, it shows how to add a username and password to the settings parameter of 
a tsNet function (which in the example is the tsNetUploadSync command).

http://lessons.livecode.com/m/4071/l/851756-how-to-upload-a-file-using-FTP

The same method works for all tsNet functions that accept a settings parameter.

Please let me know if that answers your question,

Regards,

Charles

Re: Mastering TS Net

[Charles Warwick via use-livecode]

Hi BR,

There are a series of lessons on tsNet on the LiveCode website:

http://lessons.livecode.com/m/4071/c/235433

If you are looking for an example of how to download something direct to a 
file, the lesson called “How to asynchronously download via SFTP directly a 
file” should help.

The same concepts apply for downloading to a file regardless of the protocol 
being used.

If you can’t quite find an example lesson that answers what you need, let me 
know and I will get one organised.

Charles

Usually I run Apache (with PHP/LiveCode) in docker these days.  I am not sure 
if you are familiar with it, but here is the contents of the Dockerfile which 
builds the image.  It is effectively just a script that builds a basic Ubuntu 
16:04 Linux server running Apache.

( I can successfully use the latest tsNet external with it.)

—

FROM ubuntu:16.04

EXPOSE 80

RUN apt-get update && \
apt-get install -y \
apache2 \
libc6-i386 \
libfontconfig \
libx11-6 \
libxext6 \
unzip \
wget

COPY apache2/apache2.conf /etc/apache2/apache2.conf
COPY livecode/LiveCodeIndyServer-9_0_0-Linux-x86_64.zip 
/LiveCodeIndyServer-9_0_0-Linux-x86_64.zip

RUN mkdir -p /usr/local/livecode && cd /usr/local/livecode && \
unzip /LiveCodeIndyServer-9_0_0-Linux-x86_64.zip && \
chmod 755 livecode-server && \
a2enmod actions && a2enmod cgi

COPY livecode/tsNet-x64.so /usr/local/livecode/externals/tsNet-x64.so

ENV APACHE_RUN_USER www-data
ENV APACHE_RUN_GROUP www-data
ENV APACHE_LOG_DIR /var/log/apache2
ENV APACHE_RUN_DIR=/var/run/apache2

ENTRYPOINT ["/usr/sbin/apache2"]
CMD ["-D", "FOREGROUND"]

—

The apache2.conf file that gets copied in simply sets up the livecode-server 
binary to handle .lc files - which I am guessing you are already familiar with.

Hope that helps,

Cheers,

Charles

Hi Ralf,

The issue is that any asynchronous tsNet function will fail on LC server.  I 
have not yet had time to go back and resolve the cause of this problem.

> - Although the business version licensing error is fixed the business

Are you referring to asynchronous functions that are only available in the 
business edition?  These will fail due to the same issue as tsNetGet and 
tsNetSendCmd, so no need to file a separate bug report for these.

If you are experiencing issues with other business only features, please file a 
report so that I can take a look at them.

Unfortunately, I need to find some time to look into the LC server 
implementation on platforms other than Linux before they will be viable for use 
with tsNet.

Re: Is anyone using tsNet external with LCserver?

[Charles Warwick via use-livecode]

Hi Matthias,

Up until 8.1.10, there was only one version of LC server.  It reports itself to 
the tsNet external as the “Indy” edition.  If you use the business edition of 
tsNet with it, it will fail.

You can use ‘the editionType’ to determine if LC server is Indy (commercial) or 
Business (professional).

Regards,

Charles

Re: Is anyone using tsNet external with LCserver?

[Charles Warwick via use-livecode]

Hi Matthias,

You should just need to copy the relevant tsNet external (for Linux x64 it is 
tsNet-x64.so) into the external directory from your normal commercial desktop 
installation.

After that, just make sure you call tsNetInit before making any other tsNet 
calls.

Regards,

Charles

Re: Internet library and LC9

[Charles Warwick via use-livecode]

Hi Paul,

TsNet tries to reuse existing connections where possible.  While this usually 
is very effective, it can sometimes cause delays like you were experiencing.

Try issuing the command:

 tsNetLibUrlReuseConnection false

Charles.

This gives us a clue.  It looks like your mail server is not detecting the line 
endings in the body of the e-mail.

Can you try add the following line just before the call to tsNetSmtpSync (line 
38) in the mouseUp handler of the “Send Email” button:

replace LF with CRLF in tPostData

And see if that makes any difference?

Re: tsNetSmtpSync (with attachment

[Charles Warwick via use-livecode]

Can you please download the following stack:

https://downloads.techstrategies.com.au/tsnet/debug_liburl.livecode

Open it while you have your LCMail stack open, click the “start debug” button 
in the above stack, try send an e-mail with an attachment and then click “stop 
debug” to stop the timer in the debug field.

That should generate some debug information about your SMTP connection.  If you 
can post the results of that (minus any private details) it might help us to 
work out what is going on.

Re: Not sure what to do.....can I run this by you guys?

[Charles Warwick via use-livecode]

 Hi Tom,

If the site you are trying to contact has CORS enabled appropriately, then you 
can do something like this...

With the LiveCode browser widget, you can call JavaScript functions from LC 
script and have the JavaScript functions call LC handlers in return.  
JavaScript has the capability to perform asynchronous HTTP requests.

You can create a HTML page that you automatically load up in the browser widget 
that has a small JavaScript function which you can call from LC with ‘do in 
widget’.   All this function needs to do is issue an asynchronous HTTP call to 
the URL passed to it as a parameter and when it receives the data, return it 
back to your LC script by calling a nominated LC handler and passing the 
returned data as a parameter.

The HTML page would look something like this:



Javascript Async Test


function httpGetAsync(theUrl)
{
var xmlHttp = new XMLHttpRequest();
xmlHttp.onreadystatechange = function() { 
if (xmlHttp.readyState == 4 && xmlHttp.status == 200)
liveCode.httpRequestComplete(theUrl, xmlHttp.responseText);
}
xmlHttp.open("GET", theUrl, true); // true for asynchronous 
xmlHttp.send(null);
}






You can either load that from a file into the browser widget’s URL or set its 
htmlText property accordingly...

Then in LC, make sure you register the httpRequestComplete handler so that the 
widget can call it:

set the javascriptHandlers of widget “browser” to “httpRequestComplete”

After that, add a httpRequestComplete handler to the card script to handle the 
returned data:

on httpRequestComplete pUrl, pData
   — pUrl will be the URL requested
   — pData will be the data returned from the URL requested
end httpRequestComplete

Lastly, make your async requests

do (“httpGetAsync(‘http://www.livecode.com’);” in widget “browser”

Since the JavaScript in the browser widget is issuing the requests and sending 
the data back to LC, it doesn’t need to display anything related to it in the 
browser widget itself - it can be a blank canvas.

Just be aware that the browser widget can cache URLs and there is no easy way 
(that I know of?) in LC to clear the browser’s cache... so if you see very 
quick responses on a second or subsequent request to the same URL, it is likely 
pulling it all from the browser’s cache.

Cheers,

Charles

Re: TSNet updated to include PUT and PATCH

[Charles Warwick via use-livecode]

Hi Todd,

You can use the tsNetCustom* functions to issue any HTTP(S) request type you 
require (including PATCH and PUT).  The tsNetUpload* functions are also 
effectively just a PUT request when using the HTTP(S) protocols.

Let me know if you need any more info.

Re: tsNet and Digest Authentication - some problems or better said: missing knowledge

[Charles Warwick via use-livecode]

Hi Matthias,

It looks to me that you are issuing a put URL request to the same URL each 
time?  Are you using the latest version of LC?

I think I know what is going on, but will need to generate a new tsNet build 
and get you to test to see if it resolves the issue.

Can you please raise a bug report and I will follow up there.

Re: tsNet woes

[Charles Warwick via use-livecode]

Hi Dan,

If tsNetIsSyncBlocked() is always returning true then a connection must be 
stalled.

The latest version of tsNet defaults to timing out stalled connections after 30 
seconds.  If you want to stay with LC 8.1.5 then just add the following code in 
your application’s startup:

tsNetSetTimeouts 60,0,30,6,30,1000

The last two parameters of this command mean timeout the connection in 30 
seconds if less than 1000 bytes per second are transferred over this period.

You can adjust those values to suit your application.

Regards,

Charles

Re: is tsnet downwards compatible?

Hi Tiemo,

Unless you are deploying to iOS devices, you should be ok to use the latest 
version of tsNet with LC 8.1.4.  Each build of tsNet contains iOS binaries 
specifically for the version of LC it relates to.

Re: tsNet and Digest Authentication - some problems or better said: missing knowledge

[Charles Warwick via use-livecode]

Hi Matthias,

That does sound strange.

If you download the following stack:

https://downloads.techstrategies.com.au/tsnet/debug_liburl.livecode

Open that stack at the same time as you have your application stack open in the 
IDE, click the “Start Debug” button, and try your PUT requests.

That will display some debug information that might help us work out what is 
going on.

On a related note, ‘tsNetLibUrlReuseConnection false’ should create a fresh 
connection to the server for the 2nd request, so debug with and without that 
set would be useful.

Yes, it supports digest authentication.  tsNet will automatically use the most

Using delete via HTTP will generally fail unless the HTTP server and website 
are specifically configured to allow it (it would usually also require 
credentials).  Some HTTP APIs do allow the DELETE method.  I expect this is not 
what you are after. :-)

As you mentioned above, Transmit would be doing this via FTP, but you would 
need to send your credentials as part of the request.  You can do this with put 
URL and delete URL (for any supported protocol) by encoding them into the URL 
that you use like this:

put urlEncode(“username”) into tUser
put urlEncode(“password”) into tPass
put “ftp://“ & tUser & “:” & tPass & “@ftp.mydomain.com/path/to/file.txt” into 
tUrl

I expect that would likely solve your issue, but as Richard has mentioned, 
there are security issues to be considered that are all dependant on the 
environment that you are using your application in.

Cheers.

Charles

You can use ‘delete URL’ to delete an FTP file.  If the result is not empty, 
then it failed to delete it.

You could always try the ‘put’ first, and if you get a 405 error, try the 
‘delete’.  If the delete is successful, you can ‘put’ again.  If the delete is 
unsuccessful, advise the user.

Cheers,

Charles

I would recommend using:

put URL t1 into tData

The contents of ‘it’ can be changed by other commands, so if you are having 
issues in a more complex app, maybe something else is overwriting that value?

Re: tsNet or not tsNet?

[Charles Warwick via use-livecode]

Hi Graham,

In commercial versions of LiveCode, the default behaviour of the Internet 
library (libUrl) is to include and use tsNet.

It calls tsNetInit on startup so that you don’t need to do that separately.

Hope that helps,

Charles

Re: non-blocking http ... will tsnet end up in community?

[Charles Warwick via use-livecode]

Hi Richard,

> Is it?

> DDoS tools aside , what APIs need more than one call at a time?

Not that I am Tom, but many APIs need different calls to retrieve various 
pieces of information.  Just as a simple example, if you are writing a weather 
app and you want to display on one screen the temperatures for multiple cities, 
you may have to make an API call for each city before you can render the entire 
screen.

> And since LC is single-threaded, what do you anticipate doing with the data 
> from the multiple requests as it comes in?

The issue is usually that API calls can take time for the server to respond.  
By executing them in series, if you had to make 10 calls and each one takes 
500ms, that is 5 seconds of delay.

If you can send all 10 requests at once, you are likely to be waiting less than 
1 second in total - which makes a significant improvement for user experience.

This may not be the problem Tom is facing, but it is one I deal with regularly.

Re: libUrl tsNet and socketTimeoutInterval

[Charles Warwick via use-livecode]

BR,

You can definitely monitor all of your connections that use tsNet by setting a 
status callback like you have mentioned below.

The overhead of doing this will be determined by the amount of processing you 
do within the callback function.

Cheers,

Charles

Re: TSNet error (18)

[Charles Warwick via use-livecode]

Hi Jacque,

An error code of 18 generally indicates that the server reported the transfer 
would be a certain length, and then it ended up being shorter or longer than 
expected.

In your user’s case, it sounds like the actual downloaded amount is smaller 
than it should be?  As you have said, given that other users are not having 
this issue, it doesn’t sound like a problem on the server end...

Is there possibly a proxy being used that might be getting in the way?

Regards,

Charles

Re: libUrl tsNet and socketTimeoutInterval

[Charles Warwick via use-livecode]

Hi Ralph,

There currently isn’t any ability to query the existing timeout values, though 
the default values are listed in the dictionary.  I will look to add that 
ability in an upcoming release.

If the Internet library is included in your application, it will automatically 
call tsNetInit for you on startup (which is what happens in the IDE) as it uses 
tsNet if it is available (and not disabled).

If your application does not include the Internet library, but does include 
tsNet, you will need to call tsNetInit.

Regards,

Charles

Sorry for the confusion, tsNet does handle the ‘load’ function, effectively 
using its own asynchronous functions to replicate standard libUrl behaviour.

Re: AW: tsNet and proxy servers? Charles?

[Charles Warwick via use-livecode]

Hi Tiemo,

I think it is included in LC 8.1.5 - definitely in 8.1.6.

You could also use 8.1.7 which includes a newer tsNet version (1.3.2).

To check which version you are using, open the message box and type ‘put 
tsNetVersion()’

Cheers,

Charles

Re: tsNet and proxy servers? Charles?

[Charles Warwick via use-livecode]

Hi Tiemo,

I am not aware of any issues in the latest version of tsNet with regards to 
proxy servers, however there were some fixes for proxy NTLM authentication 
addressed in tsNet 1.2.10.

Without knowing the specifics of the networks your application is being used 
in, I cannot say if that would address the issue your customers are 
experiencing.  I would recommend trying the latest version of LC and seeing if 
that resolves their issues.

You could also try get a copy of the output of the debug output from tsNet (see 
the tsNetSetDebugCallback command) from your application in one of these 
environments - it may assist in finding out what the actual issue is.

Regards,

Charles

At this point, if the speed drops below 12kbps, then the get URL command will 
return with the result set to indicate failure.

tsNet does not use standard LiveCode sockets, so socketTimeout does not affect 
connections using it.

I will get that fixed in the dictionary in the next version, thanks for letting 
me know.

tsNetSetTimeouts uses the last two parameters to determine if a connection 
should be dropped if the “average” speed of the transfer falls below the values 
set.

To use your example, if you want to ensure that the average speed of the 
transfer does not fall below 96kbps, calculating the average speed over a 3 
second period, you would specify a value of 3 for the second last parameter and 
96000 (96kbps x 1000 bytes per kB) for the last parameter to tsNetSetTimeouts.

If you are using a standard synchronous libUrl request (put URL, post x to URL, 
etc...) then the request will abort as soon as the connection speed falls below 
the threshold specified and an error will be stored in the result.

For asynchronous tsNet requests, the callback message will be sent with an 
error code indicating the failure.

Hope that helps,

Cheers.

Re: libUrl tsNet and socketTimeoutInterval

[Charles Warwick via use-livecode]

Hi Ralph,

You are correct, as tsNet does not use the standard LiveCode sockets, it does 
not pay attention to the socketTimeoutInterval.

However, rather than disabling tsNet, you can resolve any app hangs related to 
socket timeouts by using the tsNetSetTimeouts command which allows you to 
control how long the external will wait before considering a connection lost.

Have a look at the following bug report which is about a similar issue:

http://quality.livecode.com/show_bug.cgi?id=20627

Effectively the last two parameters to that command allow you to set a minimum 
amount of data that must be transferred across a connection within a specified 
period of time to consider a connection still active.

Having said that, when tsNet is disabled, libUrl should continue to pay 
attention to the socketTimeoutInterval property.

I have just done quick test on LC8.2.0dp2 and if I set the 
socketTimeoutInterval before making a “put URL xxx” call to a script that 
deliberately doesn’t respond in time, the request times out after the time 
specified by the socketTimeoutInterval call and returns a result of “socket 
timeout”.

Regards,

Charles

Re: Testing Bandwidth with new TSNet Functions

[Charles Warwick via use-livecode]

Have a look in the dictionary at the tsNetSetTimeouts command.

In particular, the last two parameters allow you to define a minimum transfer 
speed so that if a transfer falls below that speed, tsNet will abort the 
connection.

For example, if you issue the following command:

tsNetSetTimeouts 30, 0, 30, 6, 30, 1

Then tsNet will abort any connection that is transferring at a rate slower than 
1 bytes per 30 seconds.

Cheers,

Charles

Both are safe.  Generally, if you are going to be making multiple 
connections to the same server (in this case, sending a number of 
e-mails) fairly quickly, then allowing tsNet to reuse an existing 
SSL/TLS connection to the server will be quicker (it doesn't have to 
establish the SSL connection each time).

Hi Thierry,

Hi all,

I've worked hard with tsNetSmtpSync() these last days,
on macOS Sierra with the latest LC 8.1.6
and have 2 questions which bothers me:

Executing it again (same code and context) and all is fine then.


What is the error message that you get?


- about the ResponseHeaders out parameter:
tsNet will try re-use an existing connection if there is one available, 
so this first example:

Sometimes I get:

Indicates that there was no existing SMTP connection to the server, so 
it needed to establish a new connection.


Where in the following example:

or this:

250 OK
250 Accepted
250 Accepted
354 Enter message, ending with "." on a line by itself
250 OK id=1dsSmD-003WQr-2l
This indicates that tsNet found an existing SMTP connection to the 
server you are connecting to, so could just send the message across the 
already open connection.


You can add the "no_reuse" element with a value of true to the settings 
array (last parameter to tsNetSmtpSync) if you want to establish a fresh 
connection for each e-mail that is sent rather than allowing tsNet to 
reuse an existing connection.


Hope that helps,

Regards,

Charles



In both cases, the email is sent and received correctly.

Thanks for some hints.

Re: TSNet error 6

[Charles Warwick via use-livecode]

Hi Jacque,

Any of those error codes (6, 7 or 35) are reasonable if you are 
operating in an area with a really poor connection.


When you are operating on a public wifi, it could have a lot to do with 
how the wifi is configured, as Bob mentioned below.  How these are 
configured can vary greatly.


Depending on how far you want to go with testing, you could try see if 
your app can communicate with other sites when at these coffee shops.  
Does it only have trouble with HTTPS sites, or just certain sites?  If 
you browse to a site first with Chrome, does your app then work 
afterwards?  Does it have trouble if you try connect via the IP address 
rather than the hostname?


Cheers,

Charles

Short answer yes. Long answer Charles is going to write some docs or a demo to

IMAP and POP3 support in tsNet under Linux is only available in tsNet 
1.3.0+ which will be bundled with the next LC release.


All other platforms have had support for those protocols for a while.  I 
hope to have some documentation available in the next two weeks.

Re: AW: load URL is broken in 8.1.4

Hi Tiemo,

My apologies if there was a regression due to tsNet in those particular 
versions.


Between tsNet 1.2.7 and tsNet 1.2.8, the only change to the Windows 
build was an update of the underlying curl library that tsNet uses.


While that does open the possibility for a regression, the underlying 
curl library remained the same between tsNet 1.2.8 and tsNet 1.2.9 
(which I believe you are not having the issue with).

Hi Tiemo,

The "load url" call does use tsNet if you are on Indy or Business. In fact
every network-related operation does use tsNet on Indy and Business.
Moreover, the tsNet external was updated in LiveCode 8.1.4 rc2 (to fix bug
http://quality.livecode.com/show_bug.cgi?id=19026), so it quite possible
that this update has caused the regression you experienced in 8.1.4 stable.

For reference, those are the tsNet versions that are included in the LC
recent versions:

LC 8.1.4 rc-1 : tsNet 1.2.7
LC 8.1.4-rc-2 until 8.1.4 stable: tsNet 1.2.8
LC 8.1.5 stable: tsNet 1.2.9
LC 8.1.6 rc-1 until 8.1.6 stable (to be released very soon): tsNet 1.2.10

When a LC release includes a new tsNet version, this is mentioned in the
release email.

So I would guess that tsNet 1.2.9 has caused this bug for you in 8.1.4,
which was fixed in tsNet 1.2.10 (included in LC 8.1.5).

Hi Mark,
thank you for your explanations. What I can understand are the
regressions switching from 6 to 7/8, because of widely new underlying
architecture and components. That was a huge step. There I had a lot of
sympathy. What is much more harder to understand and acceptable are the
regressions within version 8. I would think that there is not such a
general exchange of components under the hood from 8.1.4rc1 to 8.1.4, which
would make a total test of every detail necessary. My first idea was a bug
in tsNet.dll, but this "load URL" bug is not caused by the different
versions of tsnet, but definitively by LC 8.1.4.

I don't think there is anyway we can deny that the transition from 6.x to
7.x caused a lot of regressions.

This is why we have a strict policy of handling maintenance releases now
- i.e. we work very hard to ensure each maintenance version is strictly
better than before.

I know of a number of users who have had similar difficulties moving from
6 straight to 8 - however, barring the occasional error (e.g. The backdrop
fiasco and the load URL one you mention directly) 8.1.(x+1) has had less
regressions relative to 6 - and no regressions relative to 8.1.x.

Also (as far as we can) regressions relative to older versions get very
high priority in our bug fixing queue.

So things might not yet be perfect but I'd hope that everyone can see
that we've made great strides (indeed, we've made good progress on fixing
issues which have been around a lot longer recently - even back to the very
early days of the MetaCard engine).

No-one likes encountering regressions - however in a system as complex
and broad as ours they are often unavoidable.

Every one sees a different view of the elephant so to speak - and we try
to act as quickly as we can when issues are reported (usually seeeing them
fixed in the next maintenance release).

Warmest Regards,

Mark.

If it has been unloaded, then you would need to specifically include the 
tsNet inclusion to be able to use tsNet commands directly.


If the tsNet is actually loaded, then including the Internet library 
will automatically include tsNet as well (as tsNetInit will 
automatically be called on startup of revLibURL).

Re: [ANN] Release 8.1.5 -- tsneterr

[Charles Warwick via use-livecode]

Hi Dan,

The resetAll command is very destructive, in that it closes all 
currently open connections.  In certain circumstances it has been 
required when using the traditional libUrl library to work around 
network errors and in order to maintain feature parity, it does also 
work with tsNet.


However I generally would not recommend using it with tsNet as there are 
other mechanisms available in tsNet to enable it to handle network 
problems more gracefully.


I recommend taking a look at the tsNetSetTimeouts function that is 
available in tsNet 1.2.10 (which is included in LC 8.1.5).  In 
particular, have a look at the pLowSpeedTime and pLowSpeedLimit 
parameters to that function.  They allow you to set a minimum number of 
bytes that must be sent/received within a specified time period for the 
connection to be considered acceptable by tsNet. If the speed of 
transfer falls below that amount, the connection will be timed out 
returning control to your script.


This should prevent connections from stalling and not returning - which 
is generally where the use of resetAll comes into play.


If you are using apps within a mobile environment where network 
connectivity can come and go frequently, it may also be worth setting 
"tsNetLibUrlReuseConnection false" at the start of your application.


Having said all of that, it is still possible to use resetAll, though 
some care must be taken.  With tsNet, it briefly disables the external 
and then re-enables it.  My guess is that another handler is trying to 
process a URL request while the resetAll is being performed.


The easiest way to see if tsNet is in use by libUrl is:

putthebehaviorofstack"revLibUrl"intotLibUrlDriver
if tLibUrlDriver isemptythen
answer"tsNet is disabled"
else
answer"tsNet in use"
end if

Best Regards,

Charles

It seems to be happening when one network connection isn’t finished and it

 So, I’m pretty confident it’s something with tsNet.

If it’s because tsNet calls are crashing into each other, and If all calls [by 
default] are blocking, how could one connection be started before the previous 
one is completed?

I had this problem with previous versions of 8.1, but I was hoping it would be 
fixed in 8.1.5.

Anyone have any insight?   I would very much like to move forward with tsNet, 
but if this isn’t resolved, I can’t.  Is it possible to continue with 8.1.5, 
and still use the old libURL?

I'd do an initial version for that which would handle Ubuntu 14.04 and

Do we want VPS, or should we consider versions for shared hosts? There

not sure if he needed asynchronous put, post or delete but that’s also 
something libURL doesn’t do. So the sockets are fine it’s just libURL 
implementation that would need some help to meet Todd’s requirements.
In Todd's application there was a requirement for asynchronous HTTP POST 
requests which aren't supported in libURL.


Without tsNet, POST requests need to be sent in series "post tData 
to url xxx", wait for the response and then issue the next post.   From 
memory, his application sends over 1000 POSTs to perform a sync and 
running them "one at a time" really slowed the process down.


By using the asynchronous POST capabilities of tsNet, a lot of these 
requests could be sent without waiting for others to complete.  This is 
what provided the dramatic performance improvement he saw.

No.  tsNetInit is automatically called on startup as part of libUrl 
initialisation.

tsNet has a number of different settings related to determining if a

Having said that, I am in the process of adding the ability to change

Re: urgent iOS internet issue (url request timeout setting?)

[Charles Warwick via use-livecode]

Hi Terry,

I think this is the same issue as has been reported here that I am 
looking into:


http://quality.livecode.com/show_bug.cgi?id=19656

At this point in time, issuing "tsNetLibUrlReuseConnection false" is the 
best solution, as this will stop tsNet from trying to re-use an existing 
open connection to a server.


If you are using tsNet functions directly, the equivalent option can be 
set by using tSettings["no_reuse"] to true and passing that to the 
function.  For example:


local tHeaders, tRecvHeaders, tResult, tBytes, tSettings
put true into tSettings["no_reuse"]
put tsNetGetSync("http://www.livecode.com;, tHeaders, tRecvHeaders, 
tResult, tBytes, tSettings) into tData

Charles

Thanks Dan, but that is not what I am after…

I have a server side liveCode application, which needs to talk to a couple of

not do so on Server, as Server lacks some libURL functionality. First 
workaround was to shell out to cURL. This works nicely on Mac and Linux

support. So the next thought was to call a liveCode executable -ui when needed, 
but I do not get a result back there. I will not want to have a liveCode

simply kill off the idea to treat liveCode server as a replacement for PHP and 
just bite the bullet and build everything in PHP instead. Or start an 
initiative to get libURL ported to server. I already talked to the guys in

could afford alone. I might just go with having the single command implemented 
I would need for the project (libURLLastRHHeaders), which then would also lift 
the requirements for having to use cURL or any other helper app in my case, but 
I am not quite sure if that makes sense…

Would anybody else like to see libURL feature parity between Desktop and Server

Question:  libURL has a VERY convenient feature in which if you're uploading to 
a path that includes a folder that doesn't yet exist, it'll create that folder 
for you.

If tsNet doesn't provide that, is there any better method for doing that than 
obtaining a list of directories for even folder level and explicitly creating 
one if not found?

I can write code for that, and probably cache results as I go to minimize the 
number of times I need to do that, but it would sure be more convenient to 
discover that there's some means of getting that libURL convenience in tsNet.

Re: tsNet docs?

[Charles Warwick via use-livecode]

Hi Richard,

I think I am noticing a potentially related bug when an invalid path is 
used in the SFTP transfer - I am looking into it now.


Can you confirm that you are using the complete path for the destination 
path in the URL?  Unlike FTP, SFTP paths are not relative to the user's 
home directory.


For example, if a user's home directory is /home/bob and you want to 
upload a file "test.txt" to the /home/bob/uploaddir/ directory, the URL 
would need to look something like this:


sftp://my.sftp.server.host/home/bob/uploaddir/test.txt

Please file a bug report and I will get an updated version out for you 
to test and see if we can confirm this is the same issue.


Cheers,

Charles

Thanks.  I'm no longer getting the license error with either FTPS or 
SFTP, and indeed I was able to upload a file with FTPS so that much is 
good.


With SFTP, however, I'm getting weird results, something I've never 
seen before, like LC is in some sort of semi-hung state.


I fill in the relevant fields, click "SFTP Upload Example", but then I 
don't get anything in the Results field and as long as I care to wait 
my CPU monitor shows LC churning up about 23%, but there's no visible 
indication that anything's happening.


Hoping to explore the script to guess what might be happening, I found 
I could switch tool modes and right-click on the button, but when I 
select "Edit Script" in the popup button nothing happens.


At that point some things are unresponsive, others eventually become 
responsive after long delays, and -- weirdest of all - after I quit C 
it's still shown as a process in my process list.


This is on Ubuntu 14.04, with LC v9 DP6.

Any other info I can provide?  Should I file a formal bug report on this?

Re: tsNet docs?

[Charles Warwick via use-livecode]

Hi Richard,

Firstly my apologies on the lack of documentation, it is definitely on 
my todo list and I am working on some Livecode lessons for tsNet at the 
moment.


I have just double checked that stack and noticed that the call to 
tsNetUploadSync is using the wrong syntax (it changed at one point) 
which could be causing you issues.


An updated version is now available at that same URL with the corrected 
the syntax for that call and another button so that there are now 
examples for both uploading via SFTP and FTPS.


These should work correctly on Indy and I have confirmed that here.  Are 
you by any chance trying to use the tsNetUploadFileSync command instead 
of tsNetUploadSync?


If so, these are only supported in the business edition if you are 
trying to use SFTP.


Regards,

Charles

I'd like to test uploading a file via SFTP and also FTPS, synchronous

After hunting around via Google I manage to turn up this stack from a 
blog post:
 



But when I run a modified version of the "SFTP Upload example" button 
I get an error complaining about it being unlicensed.


I'm using Indy, and I believe synchonrous upload vis SFTP is supported 
with Indy, no?


Anyone here have a concise example of synchronous uploading via tsNet?

Hi Bob,

tsNet calculates the public key from the private key, so you only need 
to pass the private key to the tsNet functions.

Re: SFTP with .PPK file

[Charles Warwick via use-livecode]

Hi Steve,

Ahh... it's been a while since I wrote the SSH component of tsNet and 
I've been unfortunately relying on the documentation I wrote when 
checking your code!


tSettings["ssh_private_key"] must provide the "path" to the private key, 
not the contents of the private key (another documentation issue for me 
to fix!).


So your code should actually look like

on mouseUp
  local tHeaders, tResult, tSettings
  put “" into tSettings["username"]
  put "D:\private.ppk" into tSettings["ssh_private_key"]
  tsNetInit
  put tsNetGet("1", "sftp://secure..us/;, tHeaders, 
"transferComplete", tSettings) into tResult

end mouseUp

Hopefully that will get it working for you!

Cheers,

Charles

I made the change below, and indeed didn’t get the error any more. However, I

I ran your debug stack along side it and got this:

Not sure about were to go from here… I redid the export of the .ppk in PuttyGen 
and still get the same thing. There is no password protecting the key.

The array element for the SSH private key should be tSettings["ssh_private_key"], not

Re: SFTP with .PPK file

[Charles Warwick via use-livecode]

Hi Steve,

It looks like you are using a SSH private key in PuTTY format (.ppk).  
tsNet requires it to be in OpenSSH format.


That is easy to fix though, you can convert the .ppk with PuttyGen.

To do this, open PuttyGen and load the .ppk file.  Then select 
"Conversions" -> "Export OpenSSH key".


Apart from that, just make sure that your call to tsNetGet includes the 
full path of the file you want to download.


Hope that helps,

Cheers,

Charles

Well, still no luck in getting it to work, but getting closer…

I found a sample file linked to on livecode.com . 
Modifying it to use the key file, I have:

on mouseUp
local tHeaders, tResult, tSettings
put “" into tSettings["username"]
put URL "binfile:D:\private.ppk" into tPrivKey
put tPrivKey into tSettings["ssh_priv_key"]
tsNetInit
put tsNetGet("1", "sftp://secure..us/;, tHeaders, 
"transferComplete", tSettings) into tResult
end mouseUp

However, it returns:

  tsneterr: (67) Authentication failure

Again, I can access the sftp site with no problems using the WinSCP ftp client 
and the key file.

Any suggestions??

Thanks,

Steve MacLean

Hi All,

Looking to use tsNet to connect to a SFTP server that uses username and a 
private key instead of a password. The private key is contained in a file.

I use WinSCP and can link the connection to the file and can connect fine.

In LC, I’ve set the CABundle to the file, but am not sure this is how it’s 
supposed to work. Getting an auth error when doing tsNetGet.

Any help would be appreciated.

Thanks,

Steve MacLean

Re: ulExtIsBlocked

[Charles Warwick via use-livecode]

Sounds like the tsNetLibUrl stack may have been unloaded.

Is it possible this bug is affecting you?

I keep getting this message, both in the IDE and in a standalone:

 Message execution error:
 Error description: Function: error in function handler
 Hint: ulExtIsBlocked

It's either a libURL or TSNet error, so it looks like a thing for 
Charles W. Thoughts? I need a workaround.

Re: TS Net for Indy vs Business

[Charles Warwick via use-livecode]

Hi Bill and others,

I appreciate the feedback regarding the feature breakdown between the 
different licenses.


The decision to split the features (and how they were split) across 
Business and Indy was decided on by the LiveCode team.


I expect that some of them may have seen this thread, however I 
recommend contacting them directly if you want to ensure that they hear 
your thoughts.


Regards,

Charles

It also seems to me like this is a vital feature that could cripple some 
applications. I agree with the other posters that the Indy version will 
probably be purchased by the great majority of those who purchase licenses. It 
“should” be a big market.

Best,
Bill

LC needs to reconsider breaking up functionality based upon licensing.
