remove a deployed artifact from clojars?

[Kyle R. Burton]

Hi,

I just published a project [1] to clojars and neglected to use an
organization.  I don't really want to claim a top-level name for the
project.  Is there a way to unpublish, remove or otherwise deprecate a
project that I've pushed to clojars.org?  Sorry if it's obvious and I'm not
seeing it in the clojars interface.

Re: Jobs in clojure.

[Kyle R. Burton]

There are at least two companies in Philadelphia that use Clojure:

* Relay Network (their engineering office is in center city Philly)
* RJ Metrics

I don't know if either is looking for interns, I think both are hiring.  I
used to be at Relay and can put you in touch with people there.  I've never
worked for RJ Metrics, but have worked with several of their people - I'd
be happy to put you in touch with them as well.

Best Regards,

Kyle

Re: Largest Clojure codebases?

[Kyle R. Burton]

At the last company I was with I used sloccount [1] to analyze the
codebase.  I concatenated all the clj files to a .lisp file so sloccount
could analyze it.  I was curious about the cost estimate that sloccount
performs to see how the team measured up (size varied from 2 to 7 over 5
years).  When I did the analysis (over a year ago) we had about 130k lines
of Clojure that represented about two dozen libraries and bout six
services.  Including the javascript, java, C, Ruby and other languages in
our repositories, sloccount estimated over 5x the person years we actually
spent.  This team was also responsible for the whole stack - production
operations, releases, etc.  If someone is doing research, I'd be happy to
reach out to a colleague to see if they would run the analysis again.

Understanding that this may break existing code (how much?), I think it

Looking for ideas for a hack-night to contribute back

[Kyle R. Burton]

All,

We run a Clojure group out of our company's office.  We want to put
together a hack night where we work on something meaningful.  To that end I
thought I'd put that question to the wider community: what could be
valuable to the community for us to work on?  The group has a pretty varied
amount of experience, some of us use Clojure every day, some are new to it.

[ANN] clj-xpath 1.3.3

[Kyle R. Burton]

clj-xpath is a library that makes it easier to with XPath from Clojure.

I've never announced this library before (or any for that matter).  Someone
recently sent me a pull request to fix an issue in the README (during the
Conj) so I thought I'd announce it to solicit feedback.

The Leiningen coordiates are:

  [org.clojars.kyleburton/clj-xpath 1.3.3]

An introduction and some documentation is available here:

  http://kyleburton.github.com/clj-xpath/site/

The project is on github here:

Looking for help with a deadlock issue

[Kyle R. Burton]

I encountered a deadlock on one of our production systems (one out of
3) last night.  Looking at a thread dump of the JVM, there are several
(over 200) threads that are all waiting on a
java.util.concurrent.locks.ReentrantLock from Keyword.intern.

I've put up the thread dump and information about the os and jvm versions here:

  https://github.com/relaynetwork/20120727-deadlock-issue

The part of our application that deadlocked is a web service that uses
Compjure and Jetty.  Other parts of the application did not deadlock
(we have AMQP consumers that were still processing successfully).

I have since restarted the service and it is processing again.  I'm
not sure what to look at next, can anyone suggest a next step for
determining the cause?

Re: Assuring avalaibility of ring web apps

[Kyle R. Burton]

 I'm not personally using this but people I trust recommend it highly.
 It has a free option plus fairly reasonable monthly options.

 http://www.pingdom.com/

We use a similar service: cloudkick

We have some custom plugins that we've written for it (to monitor
RabbitMQ consumers and queue sizes -- we have had consumers die and
need to be restarted).

As you are, we are using Nginx.  We have it set up to serve static
content and act as a load balancer and to do SSL termination.  We have
a cluster of app servers set up behind this Nginx load balancer.
Having multiple app servers helps significantly with issues like a
single box going out.  We have 3 configurations for the load balancer:
an A, a B and A+B.   Where each has 50% of the app servers configured.
 Nginx handles any one of the app servers being down, and we perform
releases, we split the cluster in to A, deploy to the boxes in B, wait
for the JVMs to warm up, the flip A and B and release to the A
partition.  When those JVMs have warmed up we put them all back into
rotation (A+B).  We use a symlink to point to the 3 configurations and
do a HUP on Nginx to have it reload its configuration without dropping
any connections.

We're not on AWS yet, if we were I think the same would be
accomplished with ELB instead of Nginx.

I think this is a pretty common set up -- we are following the books:
Scalable Internet Architectures, and Release IT (I highly recommend
both of those books).

Kyle

Re: Macros to help writing closures?

[Kyle R. Burton]

 (defmacro foo [fname  body]
   `(defn ~fname []
  (let [~'log (~'makeLogger ~fname)]
    ~@body)))


You may be able to do this as:



(defmacro foo [fname  body]
  `(defn ~fname []
 (let [~'log (~'makeLogger ~(str fname))]
   ~@body)))

Macros can call other functions - so you may be able to just stringify
the function name.

HTH,

Kyle

Re: Creating Java array of specific type

[Kyle R. Burton]

 If I have a seq of NameValuePair (a class in Apache HttpClient), how
 do I get an array of that type (NameValuePair[])? I've tried a few
 things but always got Object[].

Two quick ways are make-array and into-array:

   (make-array String 10)

  (into-array String [this that])

These both result in a type of String[].


HTH,

sql and cursors

[Kyle R. Burton]

As far as I can tell, contrib.sql's functions do not use database
cursors (at least for PostgreSQL, again as far as I can tell).  For
result sets that are larger than you'd like to load into the running
process, but rather step through the results and have them fetched on
demand from the server, I've tried creating a version of
with-query-results that does this:

(ns db-utils
  (:require [clojure.contrib.sql :as sql]))

(def *default-fetch-size* 50)

(defn with-query-results-cursor [[sql  params :as sql-params] func]
  (sql/transaction
   (with-open [stmt (.prepareStatement (sql/connection) sql)]
 (doseq [[index value] (map vector (iterate inc 1) params)]
   (.setObject stmt index value))
 (.setFetchSize stmt *default-fetch-size*)
 (with-open [rset (.executeQuery stmt)]
   (func (resultset-seq rset))

  ;; example usage:
  (sql/with-connection db-conn-info
(with-query-results-cursor [SELECT * FROM table_name]
  (fn [rs]
(doseq [rec rs]
  (printf rec: %s\n rec)

The Postgres documentation states that auto-commit must be off and the
fetch size must be non-zero for the cursor to work correctly.  Is
there any interest in folding this into contrib.sql?

Best Regards,

Kyle Burton

sql utilities

[Kyle R. Burton]

I've written some sql helper functions that will do things like list
the objects in the database and describe a table.  I've found these
handy when doing interactive development as I don't have to jump over
to another app to see what the make up of tables are.  I've also used
it in some scenarios when generating code from the database schema.

The functions are below, they make use only of standard JDK java.sql
functions and classes.  I'd like to see if there is any interest in
adding these to one of the contrib libraries - I'd be happy to clean
them up, create a patch or send a pull request (I've already submitted
a contributor agreement).

Best Regards,

Kyle Burton

Re: sql utilities

[Kyle R. Burton]

 This is fantastic! Does it work reliably for most JDBC drivers? Some
 drivers may not implement meta data API very well, and some drivers
 may have their own idiosyncrasies. You can perhaps setup a GitHub
 project and push to Clojars if this doesn't get into contrib any time
 soon.

I have made an attempt to use only standard SQL and standard JDK api's
- I have tested it against MySQL and PostgreSQL successfully.  I don't
have access to other databases.  I'd be happy to put it into a github
project, but thought I'd offer it to the group first.

Kyle

Re: A simple csv parsing library

[Kyle R. Burton]

 I've added my work on the csv reader/writer library to github
 (http://github.com/jonase/cljcsv). Please let me know If anyone finds
 it useful.

Thanks for the implementation, I'm very encouraged that you followed
the RFC (I've seen lots of implementations that haven't).

I took a quick look at both yours and clojure-csv [1].  I'm not using
the 1.2 snapshots so I wasn't able to try out your implementation, but
I did notice clojure-csv is lax about invalidly formatted files - if a
quoted field ends the file but is not terminated before eof, it does
not signal an error.  I think I recognize the same behavior in cljcsv
as well (though as I said I could not try it).  It might be nice to at
least have an option which allows an unterminated field to be
recognized.

Best Regards,

Kyle

 Hi there

 I built a simple csv parsing library[1] last weekend which I want to
 show you guys. It follows the RFC 4180[2] pretty closely but it allows
 for any character as separator and quote mark. It would be great if
 someone would take time and read the code. I would like to know:

 a) Can performance still be improved?
 b) Is it idiomatically written?
 c) What should an idiomatic csv parsing API look like in Clojure?
 Currently there is only one public function, 'parse' (like
 clojure.xml).

 The end of the file contains a few usage examples.

jrclj: library for calling clojure from JRuby

[Kyle R. Burton]

Hello,

We've been using Clojure and JRuby on a project at work.  For that
project we've got libraries we implemented in clojure and an
application in JRuby - so that we can call the clojure libraries from
the JRuby code I wrote a library, JRClj, to make api easier to deal
with.  The project is installable via jgem, and is on github here:

 http://github.com/kyleburton/jrclj

The JRuby code then looks like this:

  clj = JRClj.new clojure.contrib.str-utils
  puts clj.str_join :, [1,2,3]
  # prints '1:2:3'

I know cross JVM language invocation has come up on the list before so
I thought the list would be interested in the library.

Best Regards,

Kyle Burton

Thank you!

I have not yet picked a license for the library, I am open to any of

Re: Remote swank cannot recconnect

[Kyle R. Burton]

 I've setup slime to remote repl according to
 http://asymmetrical-view.com/2009/08/20/emacs-slime-remote-repl.html
 So far so good (there are some issues, but that other time).

 There is a problem with reconnecting to the remote machine after the
 connection is broken (running on wifi). I have tried also to telnet (at the
 remote machine) to the specified port and connection refused :(

 So I have kill the REPL every time is happens and of course I am loosing all
 the testing stuff in repl.

 Anyone having same problems? Solutions?

Lukas,

If you've lost your network connection, you will probably need to both
re-establish the ssh port forward (i.e. kill the ssh connection -- try
enter ~ .), and run M-x slime-disconnect from your local Emacs.
When the network connection is lost you will likely have to set up all
the parts again - though when I've done it before swank continues to
listen and I can re-establish the port forward and connect again.

In that article I advise against making the swank listener bind to a
port that is open to the internet, which is why I have the example off
using ssh port forwarding.

After your network connectivity returns, can you ssh into the remote
machine again?


Let us know how it goes.

Regards,

Kyle

Clojure, Maven and Swank

[Kyle R. Burton]

Hello,

I was wondering if anyone else had run into these issues or might know
what we're experiencing.

Our project is using the maven clojure plugin (works superbly) and
swank.  We have a long running service that both runs a swank listener
and a Repl when it starts (so we can connect to and interact with it).
 We've listed swank-clojure as a dependency in the pom.xml file, but
if we require swank.swank from the ns definition in clojure, then
something strange happens: the maven compilation hangs just after the
clojure compiler prints out that it's compiling the last of our
clojure files.  As far as we can tell, neither mvn, or java are doing
anything useful - strace shows that the parent java process (mvn) is
in a call to futex and the child process is in the same system call.
Whatever they are awaiting eventually happens and the compile finishes
- though it takes a significant amount of time.  Removing the require
eliminates the mysterious hang.

We've worked around this by not doing the require in the ns
definition, still mentioning swank as a dependency in the pom, using
assembly:assembly to build a full jar (which includes swank correctly)
and then a simple runner clojure script to require swank and then run
our serivces.

Has anyone else seen this or know what we might be experiencing?

clj-xpath

[Kyle R. Burton]

Hello all,

We needed to use xpath at work, and though zip-filter is nice, it
isn't actually xpath and that's what we wanted in this case - so we
wrote a little wrapper library to make using xpath from Clojure
simpler.  I've put the library up on github here:

  http://github.com/kyleburton/clj-xpath

I may not have searched well enough, but I was unable to find anything
that looked like it fit our needs before we embarked on writing this
(admittedly lightweight wrapper library).  We found it useful and
wanted to offer it back to the community.

Any feedback, pointers to other libraries or suggestions will be
greatly appreciated.

Best Regards,

Kyle Burton

Re: binary serialization

[Kyle R. Burton]

 Is there a way to do binary serialization of Clojure/Java values?
 ASCII (read) and (write) are nice, but they are wasting space,
 truncating floats and are probably slow compared to binary
 serialization.

The following utility functions have worked in many cases for me:

(defn object-file [obj file]
  (with-open [outp (java.io.ObjectOutputStream.
(java.io.FileOutputStream. file))]
(.writeObject outp obj)))


(defn file-object [file]
  (with-open [inp (java.io.ObjectInputStream. (java.io.FileInputStream. file))]
(.readObject inp)))

(defn freeze
  ([obj]
 (with-open [baos (java.io.ByteArrayOutputStream. 1024)
 oos  (java.io.ObjectOutputStream. baos)]
   (.writeObject oos obj)
   (.toByteArray baos)))
  ([obj  objs]
 (freeze (vec (cons obj objs)

One caveat though is that currently some of the clojure data types
(like Symbols) that I thought would have been serializable are not.  I
think that in the case of Clojure symbols it is being addressed
though.

Hope this helps,

Regards,

Kyle Burton

Re: creating classes in Clojure

 Is there a way to create a Java class (not instance) in Clojure

Yes, tho perhaps not according to the example you have there.  You can
complie a clojure file by using gen-class:

  http://clojure.org/compilation

gen-class does support a state declaration, but it doesn't seem to map
cleanly to member variables as in your example. What is probably more
idiomatic on the clojure side is to use a map for such a data object.

I wrote up an example that uses gen-class and ant to create executable
jars here:

Re: binary serialization

[Kyle R. Burton]

 Does all this work with cycles, Java arrays, etc.?


It will work with anything that implements the Serializable interface
in Java.  Arrays do implement that interface, as do all the
primitives.  With respect to cycles, I'd suspect it does, but would
test it.  If you have a repl handy it should be pretty easy to test
those functions out on your data structures.

What class has the cycle?  Is it a standard collection?

Kyle

Re: executing tasks on a schedule

[Kyle R. Burton]

I wrote a basic quartz adapter for calling clojure functions by
submitting a job to call a clojure function by namespace/name or
submitting a closure.  My write-up is here:

  http://asymmetrical-view.com/2009/05/19/quartz-and-clojure.html

The example quartz code is in my github sandbox:

http://github.com/kyleburton/sandbox/tree/master

For me the advantage of using quartz and clojure is that it's in the
same JVM as other parts of the application - I don't need to create a
separate command line runner which can be invoked by cron.  I'm also
exploring creating a scheduling service using Quartz listening on an
AMQP message queue - where you can send it a message with the
scheduling details (one off or recurring) a return queue and an
embedded message body.  At the triggering time it sends the embedded
message back.  This is also more flexible than Cron - it's all handled
within the application and I can register and unregister the triggers.
 Cron would be more difficult to use for cases where I want to defer
some activity by sending it to the scheduler to be returned in say 10
minutes.

The scheduler service isn't in my sandbox yet, but I do plan on
publishing it when its complete and I have the time.

HTH,

Kyle

Re: timing for map

[Kyle R. Burton]

I map produces a lazy sequence, time doesn't force it, if you wrap it
in either a dorun or doall, you should get what you expect:

user (time (map #(Thread/sleep %) '(1000 1000 1000)))
Elapsed time: 0.156 msecs
(nil nil nil)
user (time (doall (map #(Thread/sleep %) '(1000 1000 1000
Elapsed time: 3000.383 msecs
(nil nil nil)
user



I think that is what you're running into.

Clojure Talk @ Philly Java Users Gropu Tonight

[Kyle R. Burton]

I realize this is late notice (didn't think of it till now), there is
a Clojure talk tonight at the Philadelphia Java Users Group - to
attend you'll need to RSVP (see: http://phillyjug.jsync.com/ to sign
up).

The announcement is below.

Regards,

Kyle

Agenda:
6:30 – 7:00  Grab a good seat, some pizza, soft drinks, enjoy life
7:00 – 7:15  Announcements, raffles and giveaways, stretching exercises
7:15 - ??  Scott Fraser on Clojure

Speaker Bio:
Scott Fraser – co-founder, CTO of Portico Systems

Scott has worked professionally in the information technology sector
for more than twenty one years. One of the three original founders of
Portico Systems, he continues to have hands-on involvement with the
company’s Java-based platform. Previously he worked as an independent
consultant specializing in UNIX/Windows C/C++ programming, and
networking.

Scott started working with Java in 1996, and looks forward to 10 more
years with the language that single-handedly saved him from memory
leaks, Win16/32 API’s, and General Protection Faults.

He has a BS in Environmental Biology from Eastern University in St.
David’s PA, and is an avid birder.

Abstract:
Scott has always known about the coming Robot Apocalypse. But only
recently was he convinced, by a Functional Programming evangelist,
that the deconstruction of the Imperative and Object Oriented
programming paradigms that had dominated Scott's career for over 22
years might be imminent. Always paranoid about staying relevant, sure
that the JVM was here to stay, and with many years of highly
multithreaded high performance Java applications behind him, he sought
a functional language that would work for him... and was led to
Clojure.

Clojure is an exciting lisp dialect with baked in concurrency support.
It's creator, Rich Hickey, was inspired by Haskell and ML, and hopes
the language will play as a dynamic language like Python, Ruby and
Groovy, that is as accessible as those languages, but also as
performant as Java and as useful in any context as you would Java. It
sounded perfect. But could it subdue the robots?

Join Scott to learn about Clojure, and what it's creator calls it's Four Legs:

* functional programming
* lisp
* being hosted on the JVM
* direct support for concurrency

And finally, see Real World Examples (tm) of using Clojure to control
robots, for purposes of self defense, amusement of conference
attendees, and otherwise.

Re: My Clojure Emacs Setup (I'll show mine if you show yours)

[Kyle R. Burton]

I was wondering, since Emacs knows the file name (or at least the
buffer name) and line number it's sending a form from, and Clojure
represents that as meta-data (I think), could C-x C-e send that along
somehow wrapped in a form that sets these particular values for the
form that was shipped over?  Some kind of equivalent to #line and
#file (form C/C++/Perl)?

Is that possible?

Re: pattern matching in function parameters

I have no idea how much effort it would be, but I've found the common
lisp pcond library to be useful for pattern matching and a few other

Clojure, Emacs and Slime on Windows

[Kyle R. Burton]

I've followed the straightforward instructions that BC put together:

  http://bc.tech.coop/blog/081023.html

It worked flawlessly under Linux.  I have lispbox installed on a
windows machine and have been trying to get it to work on that
platform as well.  Emacs + slime + clisp does work.

I created a clojure.bat

--
@set CLOJURE_JAR=c:\Documents and
Settings\kburton\personal\projects\clojure-svn\clojure\trunk\clojure.jar
@set CONTRIB_JAR=c:\Documents and
Settings\kburton\personal\projects\clojure-svn\clojure-contrib\trunk\clojure-contrib.jar
@set CLASSPATH=%CLOJURE_JAR%;%CONTRIB_JAR%;.
@java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=
-server -cp %CLASSPATH% clojure.lang.Repl %*
--

and put it into C:\WINDOWS so it was on the PATH.  I then updated my
dot emacs file:

--
(add-to-list 'load-path C:\\Documents and
Settings\\kburton\\personal\\projects\\clojure-svn\\clojure-mode)
(add-to-list 'load-path C:\\Documents and
Settings\\kburton\\personal\\projects\\clojure-svn\\swank-clojure)
(setq swank-clojure-binary C:\\WINDOWS\\clojure.bat)
; (file-exists-p C:\\WINDOWS\\clojure.bat)
; (setq swank-clojure-binary C:\\Documents and
Settings\\kburton\\bin\\clojure)

(require 'clojure-auto)
(require 'swank-clojure-autoload)
--

Running M-- M-slime clojure^M executes the batch file, so things are
close, but I get the following in the *inferior-lisp* buffer:

--
(clojure/add-classpath file:///c:/Documents and
Settings/kburton/personal/projects/clojure-svn/swank-clojure/)

(clojure/require (quote swank))

nil

(swank/start-server c:/DOCUME~1/kburton/LOCALS~1/Temp/slime.15196
:encoding iso-latin-1-unix)

Listening for transport dt_socket at address: 
Clojure
user= java.lang.Exception: No such namespace: clojure (NO_SOURCE_FILE:1)
user= java.lang.Exception: No such namespace: clojure (NO_SOURCE_FILE:3)
user= nil
user= java.lang.Exception: No such namespace: swank (NO_SOURCE_FILE:7)
user=
user= (resolve 'map)
#'clojure.core/map
user=
--

Resolve finds a standard name, but it finds it in clojure.core.  I'm
not sure what to try next, this implies to me that the Repl is active,
but somehow didn't get bootstrapped?

Any help, advice, questions or suggestions are appreciated.

Regards,

Kyle R. Burton

Re: string interpolation

[Kyle R. Burton]

 Thanks for the macro. =)
 The str function is really a good replacement for interpolation.

Yes, thank you for the macro.  I anticipate using this approach (I'm
accustomed to it from Ruby, Perl and JScheme), but wanted to support a
way of stopping the parser (by backslashing the opening brace:
$\\{x} ).  I think adding the zero-width assertion in the re-matcher
and the replaceAll to knock the backslash out gets me there:

(defn tokenize [s]
 (let [positions (let [mm (re-matcher #\\$(?!)\\{.*?\\} s)]
   (loop [acc []]
 (if (.find mm)
   (recur (conj acc [(.start mm) (.end mm)]))
   acc)))
   intermed (conj (apply vector 0 (apply concat positions))
  (.length s))
   textposns (partition 2 intermed)]
   (my-interleave (map (fn [[a b]] [:text (. (.substring s a b)
 (replaceAll \\$\\{ \\${))])
   textposns)
  (map (fn [[a b]] [:pat (.substring s (+ a 2) (- b 1))])
   positions

Regards,

Kyle Burton

 Haha, nor did I spell- or grammar-check very thoroughly!

 I meant: I didn't test the code very thoroughly, so I hope it works at all.
