Phil Daintree's shameless lies - Part 5

Phil's claim to own the copyright of all the webERP code.

The Berne convention asserts that the copyright is owned by the author of a work unless they have explicitly handed over that ownership to a second party. It further states that no copyright message is needed to assert this right, and that proof of authorship is sufficient. Some free software projects (most notably the GNU project) ask that the copyright on all contributions be physically signed over to them. This has never been done with webERP and given that as he himself has said he has fallen out with most contributors it is unlikely that he would retrospectively given this permission.

In September 2012 Phil Daintree unilaterally took the decision to alter the footer on webERP to state that the copyright to all the code was owned by weberp.org, a domain name owned by himself. This was, in the words of Fred Schuettler (a contributor to webERP) an adolescent attempt by Phil Daintree to goad me into an argument on the subject.

However it is important to those of us who have contribute significantly to webERP (my contribution can be found by following the link Phil Daintree suggests in this email). Phil has suggested in the past that he wished to change the license to the Apache license, which would mean that anybody could take my code and turn it into a commercial closed source application. I am certainly not alone in the world of Free software by being opposed to my code being licensed in this way as a simple Google search will show you. Phil Daintree says he will swear in court to the fact that "Tim is violently opposed to this for his own reasons". This implies that:

1 - I have been violent on the subject. Even in writing I have merely stated that I don't like permissive licenses. Can Phil Daintree produce any example of violence, or would this be perjury if he swore to it in court?
2 - That my reasons are somehow devious. Is he stating that the libreoffice developers antipathy to the apache license devious?

When I queried why Phil Daintree had decided to make this change without speaking to any of the other contributors, he initially claimed that he was not the owner of weberp.org and that weberp.org was owned and controlled by all the contributors. However while trying to get the launchpad site set up by Zhiguo Yuan removed he asserts that "I am the owner of the weberp domain.". Also a simple whois search shows that Phil Daintree is the owner of weberp.org. If the contributors have any control of weberp.org then how come Phil Daintree has asserted that only content that he agrees with will be included? How come only he gets to decide who can help people on the forum? Come on Phil get real!

I then pointed out that weberp.org did not exist as a legal entity and so could not own the copyright. Phil countered here by saying that "weberp.org did exist as a legal entity by vitue of the statement ol intent". However his recent statement on this issue says "To even suggest that a domain name could actually own anything is foolishness in any event". Who is the fool Phil? It appears that he has done a 180 degree turn on this and still ended up pointing the same way!!

In English law there is a concept (and most countries have a similar concept in their law) called the man on the Clapham omnibus. This basically asks what the ordinary reasonable person approaching an issue would think. I assert that any reasonable person on viewing webERP would believe that the copyright is owned by weberp.org, and on looking up that domain name would believe it was owned by Phil Daintree, and thus the copyright was owned by Phil Daintree.

Phil Daintree now asserts that when he is saying that weberp.org owns the copyright then "any idiot" would see that he meant that the copyright was owned by the contributors. Obviously I am not an idiot then!! If this is what Phil Daintree means then why the subterfuge? Why not just say that? All I have ever asked him to do is to clarify his motives for making that change at that point in time.

Phil Daintree likes to pretend that the only person who is upset by his claims to own the copyright of all the code. Not so. This has been an going issue with other developers since that start of the project.

So I say, "Come on Phil tell us the reason you made this change".

+Phil Daintree

that he creates a COPYRIGHT.txt file in webERP he clearly lays out that the copyright of the contributions belongs to the author of those contributions, which if he wants he can then link to from the footer of every page. +Phil Daintree refuses to even consider this. People can decide for themselves why he will not make a clear and unequivocal statement like this>

Who does he think he is punishing?

Programming the KwaMoja API - Error codes

In the last couple of parts of this tutorial which can be found here

API Client Part 1 and API Client Part 2

we produced a simple client application where a user selected a location, typed in a part code and the application fetched the info about how much stock was available from that location from our KwaMoja implementation.

This code can be fetched from here:

http://www.kwamoja.com/documentation/xml-rpc_tutorial.zip

However we did not touch on what would happen if something goes wrong. Load up the application, and you should see a screen similar to this one:

Now load index.php into our editor and change the password on line 38 from 'kwamoja' to 'wrong'. Now if we reload index.php we get this screen.

As you can see it cannot fetch any locations as the authentication does not work on this kwamoja instance. However it provides us with no information about why this has happened. If you recall from the tutorials regarding the writing of the client, the XML-RPC call returns an array containing two elements, the first - $Response[0] in our client - contains an integer code, and the second the result of the inquiry, if one is expected. If the integer code is zero, this indicates success. Any other code indicates an error. These error code can be found listed here. As you can see error code 1 indicates 'NoAuthorisation' which will be the error returned if the user name or password is incorrect.

To catch the errors we create a session variable (not the best way I know, but convenient for this tutorial) to hold any error messages that happen, so that we can show the to the user. So the initialisation code at the top of index.php becomes:

<?php
    include 'xmlrpc/lib/xmlrpc.inc';
    $xmlrpc_internalencoding='UTF-8';
    include 'xmlrpc/lib/xmlrpcs.inc';
    $_SESSION['Errors'] = array();
?>

and then at the bottom of the output we have a loop to output these errors:

foreach ($_SESSION['Errors'] as $Error) {
    echo $Error;
}

Now we just need to capture that error. We need to put this code at the bottom of the GetLocations() function so that it now reads:

if ($ReturnValue[0] == 0) {
    return $ReturnValue[1];
} elseif ($ReturnValue[0] == 1) {
    $_SESSION['Errors'][] = 'Incorrect login/password credentials used';
}

Now run the index.php script again in your browser and you should get out put similar to this:

We just need to put this code at the bottom of our other functions, and then they will all be able to catch this error.

Now if we put the proper password back in index.php should work as before.

Now try entering a stock code that you know doesn't exist and see what happens. I entered a part code called 'wrong' and this is what I see.

This is not very helpful output so we need catch this error. A quick look here shows that error code 1047 is 'StockCodeDoesntExist' and this should be returned if the code we entered is wrong. So we need to capture error 1047 in the GetStockQuantity() function. The code at the end of this function now becomes:

} elseif ($ReturnValue[0] == 1) {
$_SESSION['Errors'][] = 'Incorrect login/password credentials used';
} elseif ($ReturnValue[0] == 1047) {
$_SESSION['Errors'][] = 'The stock code you entered does not exist';
}

So now the function is checking that the user/password is correct and also checking that the stock code is correct and providing useful feedback in the case of any problems. We could go on and check for other errors but this should be enough for now.

I have uploaded the new tutorial files to here.

Next time I will have a look at debugging the application when an error we haven't caught occurs.

An open letter to Phil Daintree of webERP

This page is written in response to the lies that +Phil Daintree has written about me, and spread on the internet. Despite years of searching he has been unable to find anything I have written that is untrue, and he has had to resort to vague generalities, faked emails, and badly fabricated screenshots (you can see the joins if you zoom in using any bit mapped image editor). +Phil Daintree is welcome to make any comments to these pages, as he has done in the past. If I agree with what he says I will amend my writings, if I do not agree I have allowed his comments to stand next to mine so that people can make their own judgements. I have every confidence in the intelligence of readers to make a sensible judgement based on the facts. +Phil Daintree will not allow me the right of reply to any of the lies he has told about me. It seems to me significant that he realises that if people see both sides of the argument they will see through his lies.

As with anything I publish, anybody (except the viagara salesmen) can comment on my blog. I make a public commitment that I will not attempt to forge or censor any posts, as goes on in all the communication channels on webERP. If +Phil Daintree wishes to dispute anything in this blog he is free to do so. If I am wrong I will alter my post. I trust in the common sense and intelligence of people to read the facts and to make up their own minds.

Phil Daintree was forced into issuing a public apology for his lies regarding me on the webERP developers list. I tried to post a reply to the mailing list but as always happens to my posts it was immediately rejected. I believe it makes some valid points so I publish it in full here:

Phil,
Thanks for the apology, which I accept in the spirit that it was sent.
I do think you are wrong on one matter though. You say "It is a sad reflection of the state of our relationship that I automatically assume the worst". I would rather say that "It is a sad reflection on
your perception of the state of our relationship that you
automatically assume the worst". You see every action of mine (and
anyone who has disagreed with something you have said) through a prism
of hatred that means you only want to assume that the action was in
some way aimed to get at you. It is not. There is no conspiracy to get
at you. No conspiracy to make your life hard. In all the cases where
you have read this into someone's actions there is a much simpler
explanation than that, as was the case here.
All I want is to be able to develop software in a community where
anything can be discussed without fear of threats or abuse if I say
something you don't agree with. I just want to develop software in a
community where the ownership rights of contributors are honoured. I
want to develop software in a community where all contributors are
treated with respect, not where they will be publicly belittled for
weeks when you don't like their contributions. A community where if
their contributions need improving, then they are politely helped to
improve so that they can get better.
You seem to have made it clear that this is not the sort of community
you want, and there is nothing I can do about that. You control all
the means of communication in the community and you have shown that
you are determined to use that control to eliminate any dissent. That
is why I also contribute to other projects, where the community is
more like the one I talked about above.
When I feel that the work is not going to be controversial I also
include it in webERP, and all other work is immediately available for
you to decide for yourself.
You have said before that your banning me means you no longer have to
defend your decisions. I think this is wrong. I think as the leader of
the community you have an obligation to defend your decisions if
members of the community ask for reasons.
In conclusion Phil, there are no plots or counter plots. There never
were. The state of our relationship is only within you, and you are
the only one who can break that cycle.

Thanks
Tim

Phil Daintree's shameless lies - Part 4

Lie number 6 - Phil Daintree's outrageous libel against Kalmer Piiskop and myself

I didn't intend to write another of these so quickly after the last one, but I am very annoyed on behalf of Kalmer and myself. At 12.56 pm BST on the 31/3/2013 Kalmer sent a bug fix into the webERP developers mailing list. As it was a serious problem I immediately applied the fix, and updated the webERP subversion repository.

At 22.06pm on the same day Phil Daintree then wrote a nasty and abusive email to the same list accusing Kalmer and I of trying to undermine the project by deliberately making Phil Daintree's life more difficult. He threatened me with the removal of my commit access. The basis of his accusations seemed to be that the commit produced a large diff (actually only 166 lines that takes a few seconds to scan if you view the code side by side as is possible with sourceforge). I sent the reply below to the mailing list but Phil Daintree has rejected it:

Phil,

This email is deeply offensive both to Kalmer and myself. You sent
this email accusing us of playing silly tricks and trying to make your
life difficult, whilst all that had happened was Kalmer sent a patch
to improve webERP and I committed it.

The email was sent at 22.06 BST on 31/3/13. Then at 22.17 BST on
31/3/13 you applied Kalmer's patch yourself and got precisely the same
diff back that I had got.

Both Kalmer and I are way too busy for the sort of silly games you
play. If you spent your time developing instead of trying to come up
with ever more bizarre ways to stop me helping people on the forums
webERP would be the gainer.

Where is your apology to us? Have you really sunk this low that you
should make allegations like this on a public mailing list?

Any forks I contribute to, (and for that matter the one you help
sponsor) are not in competition with us at webERP. They share code
freely. We are all after the same thing. There is no hiding code till
after the release has been done. We can (and do) take their code and
include it when we want. Please either start behaving respectfully to
the contributors to webERP or leave the project.

Thanks
Tim

As I have stated in previous blog posts I am perfectly happy to debate any issue with Phil Daintree, with no forgeries or censorship. It seems he is not so honourable as he makes these libels against webERP contributors, and then refuses that person the opportunity to respond. This is a truly despicable way to behave.

I have never, and will never do anything to harm the project. I have spent many thousands of hours working on webERP and many thousands of pounds promoting it. I find it cowardly and despicable for Phil Daintree to use his absolute control of all the project resources to spread his lies about me like this. It is about time he moved on.

Here is a screenshot of my editor showing Phil Daintree's windows line endings on his file.

Please note that Phil has now apologised for this lie. The full text of his apology is as follows:

Sorry Tim, I apologise unreservedly - I can see this is not a silly trick to make life deliberately more difficult for me. It is a sad reflection of the state of our relationship that I automatically assume the worst. I should check my facts in future.

Phil

Phil Daintree's shameless lies - Part 3

Lie number 5 - Phil Daintree makes untrue statements about me on the mailing list, and refuses me the right to reply

This is more than one lie, but to save space (there are so many lies to get through) I will combine them all into one. Here are a selected few of his untrue statements:

Phil Daintree said here http://weberp-accounting.1478800.n4.nabble.com/Copyright-td4655625i20.html#a4655722 that "I understand Tim is ranting to everyone he can off list now". This was totally untrue. The only emails I had sent to people off list were helping them with webERP queries that they had put on the list, and that Phil Daintree had rejected my replies to them on the list. I challenge Phil Daintree to find one person who had received a "rant" from me. Why does this upset me? Because Phil Daintree has sent this to a publicly archived mailing list. He refuses me the right to reply to that list to challenge this assertion. This gives credibility to his lie.
Phil Daintree said in a post to the mailing list here http://weberp-accounting.1478800.n4.nabble.com/Fwd-Web-erp-svn-SF-net-SVN-web-erp-5765-trunk-tt4656055.html that I was "..hell bent on destroying the project..". This because I had removed the trailing white space that he had put onto the end of the lines. The interesting thing here is that Phil Daintree reversed my patch, and then immediately applied it as his own work, and then in some of his recent web pages about me has even included it to prove that he has written "most of the code in webERP". If that patch shows I am "hell bent on destroying the project" then obviously so is he!! Again I was not given the right of reply. Why does this upset me? Because Phil Daintree has sent this to a publicly archived mailing list. He refuses me the right to reply to that list to challenge this assertion. This gives credibility to his lie.
Phil Daintree says in a post here http://weberp-accounting.1478800.n4.nabble.com/Fwd-Re-WebERP-developers-Tag-tt4656191.html#a4656194 that "... I get these silly emails almost daily!..". On that particular day I had just returned from nearly three weeks away trying out the new golf clubs! I hadn't even taken a laptop with me! I couldn't have been sending him any emails let alone silly ones. I do occasionally write to Phil Daintree when he has posted a lie about me, and if I send an email to anyone that mentions Phil Daintree I do copy him on it, so that he can be sure there is no rant, and so that he has the opportunity to reply! Can Phil Daintree say that he copies me on emails that refer to me? Has anyone received an email about me from him that mentions me that doesn't include me in the address? I know that many have as they have forwarded them to me. Why does this upset me? Because Phil Daintree has sent this to a publicly archived mailing list. He refuses me the right to reply to that list to challenge this assertion. This gives credibility to his lie.

On the subject of right to reply Phil Daintree can make any comments on this blog that he wants, and I publicly promise that I wont interfere with them in any way. I am more than happy to debate any issue with him, and to let others decide on the basis of the facts. Unlike him I see no need for forgery or censorship to push my point of view, I am happy for the facts to be debated and for others to decide.

As this post is basically three lies rolled into one, and its longer than I intended I will leave it there for this time.
