Curl plugin problems

Anything that goes beyond a basic up or download leads to a primitive failure:

Curl new
url: 'http://somedomain.com/foo';
request: 'DELETE'; "<-- primitive error here"
perform

In the debugger #easyStatusString returns 'no error'.

Even

Curl curlVersion

gives a primitive failure.

Any idea what I am doing wrong?

I am using the plugin that comes shipped with the latest Mac VM.

Re: [squeak-dev] Curl plugin problems

MMm the curlplugin is oh what 3 year, 6 months old. I guess interest means compiling up a new one.

A new version would be super cool, indeed :-)

Re: [squeak-dev] Curl plugin problems

Alien could be used, for reifying the Curl library in the system.

I don't have the time to do it, but i could give pointers on how to start.

Re: [squeak-dev] Curl plugin problems - CurlPlugin.1.1.0.bundle.zip

In reply to this post by Lukas Renggli

Ok, I build a new CurlPlugin.bundle for os-x Version 1.1.0

Find that via http://www.smalltalkconsulting.com/squeak.html

http://homepage.mac.com/johnmci/FileSharing.html
or
ftp://ftp.smalltalkconsulting.com

look in the experimental folder for
CurlPlugin.1.1.0.bundle.zip

Now first it's 2:00am in the morning here, and I didn't bother to test it! So we'll run on blind luck since it *compiles & links* must be ok then?

The 1.0.0 version was compiled in 2006 and statically linked to a version of curl from MacPorts for running on os-x 10.2.8

The 1.1.0 version is compiled for 10.5 (ppc, macintel 32) and is dynamically linked to libcurl supply by your operating system.

No doubt someone in Europe can let me know if the SUnits pass? If there is a lack of SUnits, then I'd suggest someone add some more
if we want to make Curl a more important part of the network transport layer in Squeak.

Yeah, that's a good idea too. Is there an Alien tutorial somewhere?

In reply to this post by johnmci

Wow, that was quick.

This works definitely much better. No more primitive failures for the
examples I gave in my mail.

Curl curlVersion --> 'libcurl/7.19.4 OpenSSL/0.9.8l zlib/1.2.3'

I'll experiment a bit more tonight and let you know if there are any problems.

The current interface of Curl is barely useable because it is
basically at the level of C. What I am trying to do is to have it
integrated with the Filesystem package of Colin.

Re: [squeak-dev] Curl plugin problems

In reply to this post by Lukas Renggli

I began working on an Alien-Curl-Wrapper too. The main problem (for me) was the missing Alien support under WIN32/LINUX. Without Alien support it is easier to use the current CurlPlugin (with the changes to add header fields to the http requests). A long time ago I requested the integration of these changes in the squeak-vm list (see http://n4.nabble.com/CurlPlugin-23-under-Linux-td276117.html#a276117)...

Re: [squeak-dev] Curl plugin problems

In reply to this post by Lukas Renggli

Unfortunately there isnt, but you have these pdf's.

I think i should do one, using AlienOpenGLLibrary as an example.

When i started working with Alien, i made a class AlienLibrary, with convenience methods for starting up.
My idea was to provide the concept of an external Library reified in the image.

You could start by looking at the class AlienLibrary and overrides of its subclass AlienOpenGLLibrary.
Create the AlienCurlLibrary, subclass of AlienLibrary and start from there.

For example an AlienLibrary needs to tell the Alien plugin ( built in the lastest MacOS vm) the location of the library. Implementing the method #libraryName .
Then you would have to provide behavior for AlienCurlLibrary, by hand, for each library method you want to call.
Again, look at AlienOpenGLLibrary for examples ( methods with no arguments, with multiple arguments ,with no result and with a result ).

Please let me know if i can help you with something else,

Fernando

So is that part fixed now?

Re: [squeak-dev] Curl plugin problems

The curl plugin works very well and is very fast for the parts that it
is supposed to work on.

The problem is, that it does not provide a complete API to all the
functionality of libcurl. For example, it is impossible to perform
more sophisticated operations on protocols other than HTTP (like FTP).
Worst of all, there is no way to work around this, because the plugin
provides no direct access to the few low-level functions of libcurl
(like curl_easy_setopt). Instead it wraps many (but by large not all)
possible parameter combinations into an army of rigid primitives :-(

I guess I'll to wait for CurlAlien to come alive.

Re: [squeak-dev] Curl plugin problems

Just a lil question: why you using curl, when you can do everything in
smalltalk,
using sockets?

Sure, that could be done if I had several years of free time and if I
wouldn't be bored reading and implementing dozens of RFC standards.
Properly supporting protocols (this is definitely not what HTTPSocket
and FTPClient do) like FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP,
TELNET, DICT, LDAP, LDAPS and FILE means a lot of work.

Re: [squeak-dev] Curl plugin problems - CurlPlugin.1.1.0.bundle.zip

In reply to this post by johnmci

Hi,

I tested a 2.0.0 version of the plugin sent to me by John, and it passes all the tests except for the timeout option test in CurlTests>>testApiOptions, which fails.

I also tested the 1.1.0 version of the plugin, but that does not pass most of the tests. I fails on primitive 'primSetOptLong'.

I use Pharo 1.0 (oneclick) on a MBP running Snow Leopard (10.6.3).
The libcurl version reported by Curl>>curlVersion is 'libcurl/7.19.7 OpenSSL/0.9.8l zlib/1.2.3'.

Kind regards,

Hein
