Question on attributes
Hi,
I am considering the use of extra attributes to store the result of a process that is executed as part of the build, just before we publish the new version. I think it would meet our needs and allow us to optimize the process of recovering this information (since we will later have to recover the module anyway).
My concern though is this paragraph in the Ivy documentation (from http://ant.apache.org/ivy/history/trunk/concept.html)
Example:
Here is an ivy file with the attribute 'color' set to blue:
<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
<info organisation="apache"
module="foo"
e:color="blue"
status="integration"
revision="1.59"
/>
</ivy-module>
Then you must use the extra attribute when you declare a dependency on foo. Those extra attributes
will indeed be used as identifier for the module like the org the name and the revision:
<dependency org="apache" name="foo" e:color="blue" rev="1.5+" />
And you can define your repository pattern as:
${repository.dir}/[organisation]/[module]/[color]/[revision]/[artifact].[ext]
It says that I “must use the extra attribute”, but what if I don’t want to? I don’t want to change the layout of my repository or change all my ivy.xml dependencies, I just want to use an extra attribute as an annotation or a tag, that I might (or not) refer to later after resolving the module.
Would that be possible?
Thanks,
Nascif

Re: Ivy 2 resolve time over a WAN
Posted by pa...@targetgroup.net.
OK, it seems to be caused by some sort of DNS problem I guess, as if you
read here:
http://www.developer.com/java/other/article.php/1551421
it says:
"So far, I have covered the most common situations where HttpURLConnection
works properly. However, I have encountered a few networks where
HttpURLConnection is not usable.
It appears that the problem is linked to a faulty configuration of the DNS
server. For some reason, HttpURLConnection always attempts to resolve the
host name against the DNS server. Normally, it fails gracefully and the
connection goes is rerouted through the proxy server. A few DNS servers
return an inappropriate answer that results in a UnknownHostException.
There's an interesting theoretical debate as to whether the DNS server
behaviour is acceptable. Although I am no expert on the topic, it would
appear it is not. However, as a developer, you seldom have the option to
reconfigure the DNS server, so you have to find a workaround."

Not sure if I sent this so will send again:
I've profiled my test case and the bottle neck is on
"getURLInfo(java.net.URL, int) org.apache.ivy.util.url.URLHandler$URLInfo"
When profiling I see that the vast majority of the time taken is in the
above method, taking on average 20 seconds per call ( I killed the profile
after a few minutes, at which time it had done 4 calls, totalling 80
seconds).

You just need to put commons-httpclient jar in your classpath and Ivy will
detect it and use it. Then to configure the logging check this page:

the other trick (on unix, anyway), is while the program is sitting

There were some issues with ivy not liking networks where the host didnt
know its own name, that made things crawl, but should be fixed now.

Presumably there is a way to turn on extra logging on in httpclient, by
using the right commons-logging settings. So when ivy uses httpclient
for its work, the log shows where it is going. I don't know the specific
log settings though.

that's the thing. Normally a host does that automatically, but for some
reason my home box is broken. If I knew what I'd done, I'd be able to
fix it, but instead I get to file bugreps against Ivy, Hadoop,
SmartFrog, etc. then the patches, as nobody else usually sees it.
If you get a hung system, do a stack trace and see if it is hung in any
InetAddress.getLocalHost() or InetAddress.getHostName() call, or any
other InetAddress operation, as they seem to be signs of DNS problems

How do I do this ? I'm fine with setting up commons logging, but my little
test case that does an install doesn't even have commons-httpclient on the
classpath.
"There were some issues with ivy not liking networks where the host didnt

What would I need to do to allow the host to know its own name ?

I have no idea what's going on, and don't even know how 27 minutes compare
to how Ivy 1.4 performed in similar environment. You can track down Ivy http
communications by using commons-httpclient and activate the logs. You may
better understand what's slowing down the process.

Could you try out a trunk version of Ivy? You're problem may be related to
slow DNS causing slow answer to InetAddress.getLocalHost().getHostName(),
that is now cached (see IVY-817)

Re: Ivy 2 resolve time over a WAN
Posted by pa...@targetgroup.net.
Here's the output of the logging produced by the triggers for an install of
"org.richfaces-library" into a local repository. It took 60 minutes in
total to run, and although the logging doesn't show it, most of the time
was taken resolving. The very slow artifact downloads are due to our
firewall software virus checking every jar, so that is a different issue.
The dependency resolution time though is very very slow. It's very fast in
the same network infrastructure using Ivy 1. If I run this install from
home it's lightning fast, so it must be something to do with the network
configuration that is highlighting a difference between Ivy 1 and 2.

It's rather difficult to evaluate performance when part of the process
involves accessing resources over the internet, served by servers which do
not always give the same response time. A better test would involve only
resources that you master, to be sure the server performance is the same
between your tests. So I can't say much on what you see, except that Ivy 2
shouldn't be much slower than Ivy 1.
There's also a way with Ivy 2 to audit some performance, by adding this to
your settings:
<triggers>
<log file="${ivy.log}" append="true"
message='resolving,,,"${module}"'
event="pre-resolve" />
<log file="${ivy.log}" append="true"
message='dependency,${duration},,"${module}","${revision}","${req-revision}"'
event="post-resolve-dependency" filter="resolved=true"/>
<log file="${ivy.log}" append="true"
message='resolved,${resolve-duration},,"${module}"'
event="post-resolve" />
<log file="${ivy.log}" append="true"
message='downloaded,${download-duration},${download-size},"${module}"'
event="post-resolve" />
<log file="${ivy.log}" append="true"
message='artifact,${duration},${size},"${module}","${revision}","${origin}","${file}"'
event="post-download-artifact" filter="status=successful"/>
<log file="${ivy.log}" append="true"
message='retrieved,${duration},${size},"${module}",,${nbCopied}'
event="post-retrieve" />
</triggers>
You will get information on where the time is spent, the file can be loaded
as a csv file. If you find one particular performance bottleneck, we are
interested!

Ivy 2 resolve time over a WAN
Posted by pa...@targetgroup.net.
Here's an example output of an Ivy 2 beta install I did earlier today. I am
on the end of a WAN. At the other end there is a firewall between me and
the internet. It seems the resolve part of the install takes ages - look at
the total time, 17 and a half minutes. How much http traffic does a resolve
involve ?
If I do the same thing in ivy 1 the resolve and install is massively
quicker.

RE: Question on attributes
Posted by Nascif Abousalh-Neto <Na...@sas.com>.
Hi Xavier,
Thanks for your reply.
Yes, that would be perfect. We already do our own parsing of the resolve reports, this step was already part of the plan.
I tried using the info attribute yesterday but didn't get very far. Although the documentation said that if I used namespaces I wouldn't have to set validate to false, the schema validation did fail the build. I just found out that this was added in beta2 as part of IVY-553, but unfortunately we are still in beta1. Hopefully we will upgrade soon.
Thanks again,
Nascif

Well, extra attributes on the info tag are considered as identifying
attributes, and as such do not really fit what you want. But if all you need
is adding data, you can put it as a subelement of the info element:
<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
<info organisation="apache"
module="foo"
status="integration"
revision="1.59" >
<e:color>blue</e:color>
</info>
</ivy-module>
Then you can use xml parsing to get the value of your extra element. Note
that this won't be parsed by Ivy itself, if you want to parse it, you can
create a custom Ivy parser extending the default one.
Does this match your need?
