Subject Re: [VOTE] Camel MUST use valid URIs for identifying and configuring Endpoints
Date Thu, 21 Jun 2012 06:23:16 GMT

a)
I am happy with the current model, and DO NOT want any changes / implications
upon the Camel 2.x codebase. Its important for me that the current 2.x
codebase is kept stable as is.
Camel 2.10 is on the doorsteps, and Camel 2.x is now 3 years old. I
want to give reasurance to the community
that the 2.x is being kept as is (stability over changes).

Camel 3.0 is IMHO the place where changes can be discussed and
considered. Not the 2.x codebase.


b)
I have not yet seen any *real* end users call out on this and having issues etc.
In fact the current model is very successful, and people build many
Camel custom components
without any troubles. And likewise using these components with the
current model is
easy for people to understand and do. People dont complain about the
style/syntax of the endpoint uris.
They are readable, easy to configure etc. And people just type what
they want, without considering
if its a spec valid URI, or that they need to % decimal escape certain
chars etc.

See: http://en.wikipedia.org/wiki/Percent-encoding

c)
Reading the reasons that Guillaume Nodet posted makes me even more
convinced to keep the current model.

d)
I want components to be as compatible with as many Camel versions as possible.
And this change causes incompatibility.

e)
Others dont mind either; In fact if you type this URL in your webbrowser
http://www.google.dk/?q={{bla}}

or I type the URL valid with the other curly brackets decimal encoded
http://www.google.dk/?q=%7B%7Bbar%7D%7D

Then Google dont mind either, it gives me the same page, and result


Lets use on of the Camel examples then (from this page:
http://camel.apache.org/file2), by typing in our web-browser
http://www.google.dk/?q=file:bar?doneFileName=${file:name}.done

And then press ENTER. Google search result is shown, and the address
bar URL is changed to:

http://www.google.dk/?q=file:bar?doneFileName=${file:name}.done#hl=da&output=search&sclient=psy-ab&q=file%3Abar%3FdoneFileName%3D%24%7Bfile%3Aname%7D.done&oq=file:bar%3FdoneFileName%3D%24%7Bfile%3Aname%7D.done&aq=f&aqi=&aql=&gs_l=hp.12...0.0.0.9447.0.0.0.0.0.0.0.0..0.0...0.0.CdzGN56g1qA&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&fp=1deded84056d2bf9&biw=1593&bih=951


If you look then the escaped URL returned from the .
file:bar%3FdoneFileName%3D%24%7Bfile%3Aname%7D.done

And that is really ugly. People should not need to type that.


And a good read about URL encoding is wikipedia
http://en.wikipedia.org/wiki/Percent-encoding

Quote from Wikipedia: Other characters in a URI must be percent encoded.
Reading that page (from wikipedia), says that other characters *must*
be encoded, and hence forcing people to use the ugly %NN style is
seriously reducing the ease of use with Camel.
