Re: [jetty-users] PathResource warn in 9.3

I commented out all the timing-failure tests, and filed a bug on the build as requested (Timeouts in BlockheadClient.readFrames()).

I wonder from the qa perspective if this could be boiled down to one sensitive test on the one point of failure.

Anyway, the build succeeds, but the documentation doesn't tell me what it created. (This is why I tried mvn compile instead of install - there is no mention of what the result is.) There is no build dir, nothing in my home dir, nothing system-installed. There is a target dir with nothing in it but an about.html and a .plxarc file, whatever that is.

What was installed, where?

Thanks,
Bill

Tried a git pull and got only java changes in the last 5 days - still looks
like a broken build -?

This is the code.

Maybe if you change line #133 from

LOG.warn("bad alias ({}) for {}", e.getClass().getName(), e.getMessage());

to

LOG.warn("bad alias [" + path + "]", e);

we can get a better stacktrace (and path indication) to know what's going
on.

It seems this is the first case of this warning on the web:

2015-07-02 13:16:57.019:WARN:oejur.PathResource:qtp1963387170-179: bad
alias (java.lang.IllegalArgumentException) for null

I'm not sure what to make of it. It is associated with a stutter
in the user experience of loading pictures.

I have web page javascript calling a servlet running under jetty
when the user clicks a 'next image' button. The servlet returns
an image file name, and the javascript loads the file via jetty
http, following a soft link ROOT/images->[...]. There is only one
user doing one thing at a time.

I am getting these warnings singly when operation seems ok, and in
clusters when the user hasn't clicked 'next image' for a while. In that
case on the browser side, in conjunction with a cluster of these
warnings, I see several images flip by in less than a second. So
images are being loaded. I need to figure out how to debug from the
javascript side and dig into the jetty source, but since PathResource
appears to be new, it seems this could be of interest.

Setup:

cd /opt/jetty-distribution-9.3.0.v20150612
java -jar start.jar \
     jetty.home=/opt/jetty-distribution-9.3.0.v20150612 \
     jetty.base=[...]/jetty-base

egrep -v '^#' [...]/jetty-base/start.ini|awk 'NF > 0'
--module=server
jetty.threadPool.minThreads=5
jetty.threadPool.maxThreads=50
--module=http
jetty.http.port=8080
jetty.server.stopAtShutdown=true
--module=servlets
