Which port does LibUrl use
Greetings two days in a row! Many of my clients have a variety of security systems or settings in place which block LibUrl's calls to put and get from our remote server. From time to time I get asked whether my standalone uses port 80 or not. I've also been asked if it could use http protocol instead of ftp (which is what I believe LibUrl is using). Can anybody shed some light on this for me? Thanks, Ray Horsley Developer, LinkIt! Software ___ metacard mailing list metacard@lists.runrev.com http://lists.runrev.com/mailman/listinfo/metacard

From time to time I get asked whether my standalone uses port 80 or not. I've also been asked if it could use http protocol instead of ftp (which is what I believe LibUrl is using). Ray, the protocol that libUrl uses depends on the url you supply. (i.e. does the url start with http://; or ftp://;?) You can use get url with either http or ftp. put ... into url ... is normally only used with an ftp url. To send data to an http url, use post ... to url ... Unless you specify otherwise, standard ports are used. (80 for http and 21 for ftp.) It's possible that your clients are using some kind of proxy server through which calls to the remote server have to be routed. You can set the httpProxy property for http urls to route calls through the proxy. If they are using a proxy server, you'll need to get the proxy details from your client and then set it in your program somewhere. For example, if the proxy server has an address of 10.0.0.128 on port 8080, you would do this: set the httpProxy to 10.0.0.128:8080 Cheers Dave ___ metacard mailing list metacard@lists.runrev.com http://lists.runrev.com/mailman/listinfo/metacard

libUrl documentation and download
Hi Until the RunRev site has the libUrl documentation back up again, you can view it here: http://www.lacscentre.co.uk/liburl/ You can also get an updater for the latest version (1.1.1 or 1.0.16) there as well. (Note that the previously announced betas of these versions introduced a bug that might affect POST commands to some http servers. So anyone using those betas should probably upgrade.) The updater is semi-intelligent in that it will install the appropriate version for the engine you currently have installed. But if you later swap engines, and keep the same mctools.mc stack, you may end up with the wrong version. So it's probably best to keep the updater around, and run it again if you ever swap engines. As discussed before, I was thinking about a more intelligent version that would keep two library stacks in custom properties, and load the appropriate one with a libraryStack handler. But I'm currently against the idea for two reasons; 1. It makes accessing/editing the script more difficult for developers, and I really want people to access the scripts and fix problems they find. 2. It's quite possible that future versions of libUrl will introduce more new syntax from newer engines, and therefore we'll need an even smarter (thus bug-prone) loading system. But as always, I'm open to opinions.

Re: new libURL?
Thank you for the summary and the URLs. Dave Cragg wrote: BTW, have you had any more thoughts on how to handle the split versions of libUrl we now have for the MC IDE? Yeah: have one version that's also backwardly compatible. :) But seriously, I've been giving it some thought and while it's easy to accomodate the IDE it's less easy to accomodate existing scripts that call start using liburl. We could do this: have libURL be just a shell whose libraryStack handler does a version check and inserts one of two button scripts into the backscripts. Can you folks think of any reason that wouldn't be a good idea? One downside is that if we continue to use Resource Mover for that it will move two copied of the script into the target stack, and only one of them is needed in a standalone.

Re: IDE and libUrl
I'd propose that we do with libURL what we did with the Standalone Builder: have two versions included in the IDE, and use the version appropriate to the engine being used in that session. Can anyone think of a downside to that? For the sake of simplicity I like being able to use one IDE build across all versions of the engine from the time the IDE went open source going forward. There may be a time when that goal is no longer supportable, but as long as it is I think it's worth doing. Any downsides to the approach for libURL proposed here? -- Richard Gaskin I think it is a good idea to have two different versions of libURL available if that is needed to support larger range of engines. The only addition to consider is being able to query the version number of the currently used one. May be it is already supported. This actually could be a common feature of all components (mainstacks as well as substacks) of IDE. In my opinion, aside from the overall release number, each component should have its own version number. Rather than creating a function for this, we could agree on all stacks having a custom property, for example, mcStackVersion, that could be queried by whatever means one desires. If we want to be more sophisticated, we could have a set with version, date, author, changes. By the way, when implementing both versions, are we going to have libURL inited at startup now or the current practice of each urlLib call librarizing it again will continue? The copy I got lately from Chipp is an installer with separate buttons for Rev and MC, so patching the code with missing libraryStack handler could be done in the installer. I am sure the author will agree with that. Robert Brenstein ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard

Re: IDE and libUrl
Ah, right. Yes that would cause extra difficulty. With that said, should the IDE generally be doing something along the lines of: try start using stack libURL catch tErr answer error Error loading libURL... version conflict? end try And would that relieve some of the problems with any incompatible library, in general? It may not be so straightforward. In the case of a new version of libUrl (= 1.1) with an old engine ( 2.6.1) I think a script error will pop up as soon as the engine tries to run/compile the script.

IDE and libUrl
Hi all First, apologies for not making a bigger contribution to the IDE. (weak excuses about other commitments, new dog ate my e-mail, etc.) As an almost full-time user of the IDE, I'm grateful to everyone involved, and especially the great poohbah. Of course, there have been times when it looked like the whole IDE might fall prey to creeping eye candy (that modernistic splash screen for example, and older users probably think things started going south when the image icon changed some years back, was that you Rossi? grin). Anyway, to more serious things... The version of libUrl (1.1a3) currently being distributed with the Rev 2.5 beta (engine 2.6.1) is not backwards compatible with earlier engines. This is because of syntax added to support secure sockets in https URLs. I plan to make future updaters aware of the engine version, and install the appropriate version. However, this might not be enough to keep confusion away. I'm not sure if the plan is to release new MC IDEs with each engine release (if so, then there mau be no problem), but I'm guessing people are hoping to be able to use the same IDE over a range of engine releases. There could be problems if people swap engines about liberally without being sure to have an appropriate version of libUrl in place. I can't think of an easy way round this problem right now. But if anyone has any thoughts, please let me know. Cheers Dave ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard

[ANN] libUrl 1.0.15 beta
Hi All A beta of the latest version of libUrl is available at the following url: http://www.runrev.com/revolution/developers/interimreleases/liburl/releases.shtml In addition to some bug fixes, it has a number of new features: It provides support for emulating htmls forms of types application/x-www-form-urlencoded and multipart/form-data. (The latter is commonly used for uploading files from html forms to web servers.) There is also support for setting callbacks to handle authentication on http and proxy servers. Except in the case of the Basic authentication scheme, this will probably require an external to implement fully. However, Chipp Walters has agrred to make available a dll that handles Windows NTLM authentication. Expect more information to be forthcoming. Note: this a beta version, so test before trusting important data to it. Cheers Dave ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard

Moving Resources (LibURL)
My question has to do with using Resource Mover to delete resources and then using it to add them back to a stack. This is happening in the context of migrating to a newer version of MetaCard and converting from Mac classic to OS X. In particular, my question relates to bringing in LibURL. Here are the specifics. My Permutation Puzzles Package was developed under MetaCard 2.3.2 for the Macintosh classic and Windows platforms. The publication of this package has been delayed long enough, so that I decided I needed to have a Mac OS X version as well. This OS X version is being developed in MetaCard 2.4.3. I have gotten everything to work under OS X and MetaCard 2.4.3 except for my system for online registration of the package. The system makes use of the MetaCard post command. Everything works fine under MetaCard 2.3.2 in Mac classic and Windows environments, and also under MetaCard 2.4.3 when the development environment is running and my program is still a stack. However once I build a standalone under MetaCard 2.4.3, the post command no longer makes contact with the server. The problem is that in the conversion to the new version of MetaCard, as I understand it, is that the handling of Internet functionality has been taken over by the libURL system. In order to incorporate this funcionality into my program, I think that I should delete resources from my stack with Resource Mover, and then add them back again. However when I do this, many other details in the package break down. I have noted this problem in the past. When I have to delete resources with Resource Mover and then add them back, things get broken that were previously working just fine. Is there a solution to this problem? Have I given enough information to make it clear? In case not, here is the script for my registration routine that uses the post command, taken from a button that the user presses after filling in a form: global gPostInfo on mouseUp if the platform is MacOS then put MacToISO(gPostInfo) into postThisNow else put gPostInfo into postThisNow end if try post postThisNow to url http://math.nmu.edu/~registrar/post.cgi; catch errornum answer Error number errornum in attempt to send your data. exit mouseUp finally put it into CheckWhatHappened if matchText(CheckWhatHappened, SUCCESS) then put You are now registered.

libUrl updates
Hi Two new updates to libUrl are available at the url below: http://www.runrev.com/revolution/developers/interimreleases/liburl/releases.shtml Please note that Starter Kit users won't be able to apply these updates. (This is not a marketing ploy; it's just because the script limits make it impossible to update your current libUrl script. Sorry!) Why two updates? Version 1.0.7b5 is a relatively minor update (one small bug fix) over 1.0.7b4 which was included with the Metacard 2.4.3 release. (More details are on the site.) Version 1.0.8a1 involves a lot of behind-the-scenes script changes, mainly affecting the way ftp commands are handled. Because of this, it hasn't been tested in the wild as extensively as the earlier versions, so you are encouraged to test it thoroughly before distributing it with your applications. However, to encourage you to try it out, it includes a couple of new features: 1. There is a callback feature that lets you get the status of downloads/uploads. It is similar in some ways to the current urlStatus function, but it will work with blocking calls such as get url. This makes it possible to report download/upload progress for these blocking calls. It should also make it easier to set up something such as a url status panel once, and then have it work automatically for all uploads and downloads without any further scripting. 2. There is now a way to switch the way that ftp directory listings are returned. You can have libUrl use the conventional LIST command (the default) which for most servers returns the conventional Unix-style directory listings. Or you can switch to the NLST comand which returns a list of file names only. Details of these features are on the website.

libUrl update and documentation
Hi An updated version of the libUrl library is available at the following url: http://www.runrev.com/revolution/developers/interimreleases/liburl/index.shtml Note that this is the same version that is included with the 2.4.3b1 Metacard release, so there's no need to update if you're running that version. However, there are notes on the site about using the library, so it's worth a visit. The new version adds commands for file-to-file transfers: libUrlFtpUploadFile libUrlDownloadToFile Notes on how to use these commands, as well as the exisiting commands and functions, are also on the site. The update also adds a few behind-the-scenes improvements and fixes. However, unless you need the above commands, or are having problems currently with ftp and http urls, you should be fine with the present library.

libURL-use in other stack/security
Aloha, I made an FTP widget for one of the editors that simply uploads an html string to a specific directory/file. Of course... (duh) when I gave it to him with the 2,4 engine and no home stack, it failed...obviously...libURL absent.. This leads to several questions: 1) it seems when in the IDE (home stack open) that the use of start using stack libURL is not required. Was this eliminated? Or is it still a good idea to uses it? But I don't think that would have solved it because: 2) Since libURL is a substack of the mctools.mc I presume that one must clone it and make the clone a substack of any stack in which you are going to use these scripts. Correct? (note, would be really handy to put this in the resource mover!) 3) How does one go about implementing progress bars and feedback from the libURL handlers?

But MC 2.4 allows that, with the help of libURL. Right ? LibURL allows you to edit it. Wht you need to edit is doProcess in libURL, not getFormat. Just add put lineOffset(Set-Cookie:,thHeader[tUrl[nX[x]]])... and deal with the data later. Normally to see the whole header you would just add a put y after on doProcess x,y. Anyway, I still don't understand everything relative to the handlers in libURL, especially getFormat, which seems to be able to do what I want. GetFormat splits the url into components: address, file name, etc. Could anyone give me a hint on how exactly use that handler to get the header in a variable ?

Re: cookie info libURL
Could libURL be extended to allow users of it to customise the headers of outgoing HTTP requests, and read the headers of incoming HTTP responses, without losing the benefits of having the library (ie, without requiring each developer to customise the library themselves). A crude (but effective) solution would be to declare a couple of global variables or properties; eg gHTTPrequestExtraHeaders and gHTTPresponse. Each call to get URL xxx would consult the first global, and set the second. It might be up to the user to empty the gHTTPrequestExtraHeaders after use, or libURL could empty it after each call. No doubt more expert MC users could propose a more sophisticated syntax (eg is it possible to make the URL support a syntax such as get URL xx with headers yy?)

Re: cookie info libURL
Could libURL be extended to allow users of it to customise the headers of outgoing HTTP requests, and read the headers of incoming HTTP responses, without losing the benefits of having the library (ie, without requiring each developer to customise the library themselves). The easiest way is to manipulate the custom properties of libURL (the headers): get the list of them, choose which one you want to change and set it to whatever you want. A replacement to the old httpHeaders I sugested is to have the library use a totally new custom header as opposed to adding to an existing one, similar to what you propose bellow. A crude (but effective) solution would be to declare a couple of global variables or properties; eg gHTTPrequestExtraHeaders and gHTTPresponse. Each call to get URL xxx would consult the first global, and set the second. It might be up to the user to empty the gHTTPrequestExtraHeaders after use, or libURL could empty it after each call.

libURL and Revolution 1.0?
I'd like to get some experience with libURL; but I'm one of those newbie types who's using Revolution. If I can work out where to download it from, should it in principle be possible to use libURL from Revolution 1.0 (which of course is based on the 2.3.2 MetaCard engine)? Are there any special things I should do or watch out for? If that's not going to work, can I ask a couple of questions about http headers - both for the request and response. Q1: As I understand it, in MC 2.3.2 you can customise the header of a request to some extent, by specifying additional text in the httpHeaders property. But I've read a message from andu (17/7/01) in which he said: No need for httpHeaders (obsolete for now) since the library implements a full header on its own. Surely there needs to be some way to specify additional headers - you can't predict what developers are going to use this for. (For example, they may need to pass authorisation through; some servers may need a host header; an app might want to specify a referrer, or a user-agent identity, etc) Is there a way to customise the request header for an http request in libURL? If not could there be, please? Q2: AFAIK, there is no way in MC 2.3.2 (ie in current Rev) to access the header of an http response. At least, I asked a couple of times on the Rev list, and nobody ever replied. I find this really restrictive - does libURL give a better solution to this? If not, could it, please?

Are there any special things I should do or watch out for? You can't use libURL with a 2.3.2 engine because the main handlers are built-in the engine and instead of having the library do the work you have the engine. You can of course get the library from 2.4 (it's a substack of MetaCard Menu Bar stack), modify the handlers so they are different from the built-in stuff and use it. Don't forget to call the library when you want to use it: start using libURL. If that's not going to work, can I ask a couple of questions about http headers - both for the request and response. Q1: As I understand it, in MC 2.3.2 you can customise the header of a request to some extent, by specifying additional text in the httpHeaders property.

(For example, they may need to pass authorisation through; some servers may need a host header; an app might want to specify a referrer, or a user-agent identity, etc) Absolutely, the headers are custom properties of the stack libURL so you can edit them at your convenience, I just didn't implement httpHeaders as a direct way to add to the existing headers, for now. Is there a way to customise the request header for an http request in libURL? If not could there be, please? Q2: AFAIK, there is no way in MC 2.3.2 (ie in current Rev) to access the header of an http response. At least, I asked a couple of times on the Rev list, and nobody ever replied. I find this really restrictive - does libURL give a better solution to this? If not, could it, please? The 2.3.x engines don't return headers in the response but you can edit libURL to do that (it deletes them at some point but you can change that). Also remember, if you are into it, you can learn to use sockets and build your own handlers for network communication and have all the control.

libURL update available!!!
I uploaded 2 stacks: update-lib.mc and liburl_update_1.mc at ftp.archeopterix.com. Start up MC 2.4B4, open update-lib.mc and just click. You'll be prompted to find the second stack and update the library in your MetaCard Menu Bar. Please keep testing and bug reporting. Scott Rossi, see if it does anything for you and let me know.

Re: Fun with LibURL! (ie, problems..)
Reed Martin wrote: Okay, Remember our pal LibURL, and how Andu told us all how to comment out the line that was unnecessary since it would leave sockets open? Well I'm now using the modified LibURL that came with 2.4B3, and having a problem... Using the post command, it seems to cut off a good fraction of the end of the file, while not closing the socket. Let's say the contents of myURL (http://www.myurl.com/mycgi.cgi) is supposed to be a\b\c\d\e\f\g\h\i (where \ is a return)... When I do: post myStuff to url myUrl put it into urlReply urlReply isn't complete (eg, it looks like: a\b\c\d\e\f\g) and answer openSockets() reveals that the socket is still open. Trying the above script with post a second time does nothing. So I close the open socket, and then try the above script using post again. This time, the last part of urlReply that was missing is at the beginning, followed by the actual urlReply data, but missing the last part again. (eg, it looks like: h\i\a\b\c\d\e\f\g) This time, interestingly, there is no remaining open socket. However, doing the post script a third time results in the above, plus the same again. (urlReply gets progressively longer with each subsequent post attempt... eg, it looks like: \h\i\a\b\c\d\e\f\g\h\i\a\b\c\d\e\f\g) Any ideas? I looked through the libURL stack script but I can't locate where the problem is. I'm guessing it's in the readmore script, but I'm just not sure. Thanks for your help!

It's technically possible to have the engine do this automatically, but I'm not sure if this is a good idea or not. It would better preserve backward compatibility (though you will still have to move the library into your application with the Resource Mover), but means hard-coding the library name into the engine, making it impossible to ever rename it or for people to add their own libraries to handle certain types of URLs differently from others.
