Out of Memory Error
hi , guys
I wrote the following codes to parse log files.
it's alright to parse small one.
But with big log files , i got the following error:
OutOfMemoryError GC overhead limit exceeded clojure.core/line-seq
(core.clj:2679)
(defn parse-file
[file]
(with-open [rdr (io/reader file)]
(println Statistic result : (parse-recur rdr
(defn parse-recur
[rdr]
(let [lines (line-seq rdr)
counts (count lines)]
(loop [len counts
res {}]
(if (zero? len)
res
(recur (dec len)
(update-res res (nth lines (- counts len
(defn update-res
[res line]
(let [params (string/split line #,)
id (if ( (count params) 1) (params 0) 0)]
(if (res id)
(update-in res [id] inc)
(assoc res id 1
How can fix this bug ?
and how to optimize this produce to run faster ?
Any suggestion will be appreciated~

Re: Out of Memory Error
Yeah, rewrite that to not hold the head of lines. In particular, get rid
of counts entirely, get rid of (nth lines ...), and use something like
(loop [lines (seq lines)
res {}]
(if lines
(recur (next lines) (update-res res (first lines)))
res))
as your loop.

Re: [ANN] Yesql 0.2.1 - Clojure SQL queries rethought.
Hi Kris,
I am not sure about that. On the other hand, it will be boring to write 20
query in 20 different files.
Could you please check:
https://developers.google.com/closure/templates/docs/helloworld_js
Here comment contains meta data for core part.
Similarly, query'd contain meta data in comment part. Query will be
identified based on meta data
(def query {:name-of-the-file {:name named-of-the-query :query
query-body :doc doc}})
Please find sql file example in bellow:
-- {:doc Counts the users in a given country. :name by_controry_code :query
SELECT count(*) AS count FROM user WHERE country_code = :country_code
-- }
-- {:doc Counts the users in a given country. :name by_id :query
SELECT count(*) AS count FROM user WHERE id = :id
-- }
Hi Mamun,
Hmm...I hadn't planned on it, but I could see it would suit some people's
development style. (It could get messy, but so can Clojure namespaces if
you're undisciplined. The developer should be allowed to take
responsibility.)
The tricky parts would be:
- How would you delimit the various queries? In a clear, portable way
that allowed for docstrings?
- How would you refer to the individual queries? Some kind of
mandatory '-- NAME: foo-query' syntax?
Any thoughts?
Kris

mean- I'd like to create one sql file and store all query on that file.

There's still plenty that can be done with the implementation, but
hopefully the world will look kindly on the design, and it can evolve from
there...

Re: [ANN] Yesql 0.2.1 - Clojure SQL queries rethought.
My primary motivation is for smoother development. Both the editors I use have good SQL modes that do more than just highlighting - they take care of schema exploration, autocomplete, indentation, memorising bind parameters, previewing results, etc. I want to use them to develop a SQL query as a separate entity, check it, and then wire it into the app later. (I also like keeping the file separate so that down the line I can easily do things like add EXPLAIN as the first line, and see what the query plan is.) Syntax highlighting is a nice to have. And I've looked in that directionhttps://github.com/krisajenkins/vim-java-sql in earlier explorations https://github.com/krisajenkins/vim-clojure-sql of the problem. For my money it's left wanting. It's better to make both languages first class citizens. There's no getting away from the fact that they're separate languages which are strong in their own domains, and are just begging for a cleaner connection point. On Monday, 11 November 2013 23:01:19 UTC, Brian Craft wrote: What prevents you from formatting the example with the clojure string of sql like the example with the separate file of sql?

Re: [ANN] Yesql 0.2.1 - Clojure SQL queries rethought.
It depends on which kind of composability you mean. If we're talking about a SELECT ... FROM ... here with a WHERE ... there, I don't see why not. It's a down-the-road feature, but I'm open to it. But the kind of composability that would get me excited is the cascalog/datalog kind. Where you could say, SELECT * FROM employee and mix that with SELECT * FROM deparment and get an automatic, sensibly-optimised join. That's real composibility, beyond mere string concatenation. No, I don't see Yesql ever supporting that. (There again, I haven't seen it from any of the Clojure-SQL-DSLs either. If you have, please point me to them. I'd be interested!)

Do (should?) these core.async utilities exist?
I've been playing with core.async, and have come across a couple of things that it seemed would probably be common use cases, but can't find anything in the library that addresses them. I'd be grateful for pointers if any of these do exist and I'm just missing them, or suggestions for reasons why I don't really want them and should be tackling the problem in a different way: A way to convert a channel to a lazy sequence (i.e. build the sequence by repeatedly reading from a channel until it's closed). It seems odd that core.async provides a means to turn a lazy sequence into a channel (to-chan) but not the inverse? An equivalent of doseq for a channel, which repeatedly reads from the channel and calls its body with the result of doing so, terminating when the channel is closed. Of course, both of these are easy enough to write, but I'm wondering whether the fact that they aren't provided as standard is telling me something? -- paul.butcher-msgCount++ Silverstone, Brands Hatch, Donington Park...

The macro that's presented there is called break. What it does is it traps the existing locals in a Clojure map when the macro is called and uses their values to eval the forms you input in the breaking repl. The version in the book uses clojure.main/repl with some options to cange the prompt, the reader and the evaler. This is exciting but is there any way to get (break) to be called when an unexpected exception is raised (in the context in which it is raised)? That would be my own #1 wish for Clojure debugging. Also nice, and FWIW also common in Common Lisp environments from ancient times, would be the ability to force a within-context call to (break) from the keyboard, e.g. when your code might be stuck in an infinite loop and you want to know why. -Lee -- -- You received this message because you are subscribed to the Google Groups Clojure group.

After saving the edited project.clj, the dependencies should be downloaded, placed in the local repository, and linked inside the Leiningen Dependencies section of your project.

cider status
The last (non-authoritative) word on cider on this mailing list[1] was that it is unstable. Is that really the case? Is it just a matter of many packages that depend on it not being updated?

[ANN] Pocheshiro 0.1.1 (wrapper for Apache Shiro)
Pocheshiro (https://github.com/inventiLT/Pocheshiro) is a Clojure wrapper for the Apache Shiro[1] security library tailored for use with Ring/Compojure. Pocheshiro is a viable alternative for Friend if you're running in a servlet container and/or already know Apache Shiro. It's a thin wrapper over Apache Shiro, the only external addition being a password hashing service with Bcrypt. This is the first public release. Any comments, reviews or pull requests are welcome! :) See https://github.com/inventiLT/Pocheshiro for more information and a user guide.

Re: cider status
I have tried it a couple of times and keep reverting back to nrepl. One of the biggest issues is nrepl-ritz which depends on nrepl and not nrepl-client. So switching to cider appears to mean ditching ritz. Name changes always cause a significant amount of distruption. I understand the rationale but only a short time after the slime/swank split it's a little unwelcome. Especially as I have code (https://github.com/phillord/tawny-owl/blob/master/emacs/tawny-mode.el) that I use daily and which depends on nrepl. Phil John D.

Re: Regarding Clojure's license
I think his main intention was to keep the traffic up on the Clojure mailing list.

Re: Regarding Clojure's license
As James said, you've misunderstood the rationale. It's also worth pointing out that a lot of US companies won't use GPL-licensed software (and won't pay for a closed source version), and many aren't comfortable with LGPL either. EPL, Apache and others are more acceptable to many commercial organizations. And, yes, I speak as someone who has had to endure the legal team of a large corporation conducting open source software audits across projects I've worked on. If you Google for differences between EPL and GPL you'll find several interesting discussions since this seems to crop up for almost every EPL-licensed project... The differences between EPL and LGPL are more subtle but still important.

Both licenses allow the creation of derived works under GPL, a license I cannot use in my work. Allowing derived works I cannot use is not reciprocal and make no sense for me. 1. First, the license allow proprietary derivative works anyway. 2. That's also the point of the GPL. It is intended to make any derivative work available to the author usable to the author. Thus, Rich Hickey's choice of the EPL has the same rationale as the GPL. That violates the principle of free software. License incompatibilities like this divide the open-source community.

Re: [ANN] Parkour: Hadoop MapReduce in idiomatic Clojure
Sam Ritchie sritchi...@gmail.com writes: Great stuff! Thanks! Just as a note, Cascalog 2.0 has a lower-level DSL that lets you write Cascading in idiomatic clojure. Here are some test examples: https://github.com/nathanmarz/cascalog/blob/develop/cascalog-core/test/cascalog/cascading/operations_test.clj Cool. I did not know about that part of the API, which does look nifty. I’m working on a blog post digging into this some, and I’m hoping to snag one of the lightning talk spots at the Conj, but – I do think there’s a big difference between writing job-flows which use a `map`-like `map*` function and literally calling `map` in a literal plain function[1]. Want a state-bearing sequence-mapping transformation? With Parkour, you can just grab bbloom’s `transduce` library[2] and it works just as well in a remote task as it does in local code, because it does in fact do literally the same thing in both scenarios. You can get similar results in Cascalog/Cascading, but need to first re-express the functionality in terms of Cascalog/Cascading’s abstractions vs just leaning directly on Clojure’s. The algebraic execution planners backing Cascading- and FlumeJava-likes allow powerful optimization of cross-task operations, but do require all transformations to be expressed in terms of primitives the planners understand. Parkour loses the cross-task awareness, but allows MapReduce tasks to do anything which can be expressed as operations on a Clojure reducible collection. This can include repeated partial reductions (even map-side), full task-partition reductions, and arbitrary numbers of disjoint task outputs. It’s not a perfect example of what I’m talking about, but Parkour does include an example implementation of the MapReduce algorithm for transforming a graph into a sparse matrix of absolute-indexed cells: https://github.atl.damballa/rnd/parkour/blob/master/examples/parkour/examples/matrixify.clj I’ll see if I can distill out a more compelling example from some real jobs prior to the Conj :-). [1] It admittedly hurts this point a bit that Parkour exclusively uses reducers instead of lazy sequences, but I’m hoping shortly to add the necessary glue to allow tasks to work via seqs too when desired.

Re: gemacl: Scientific computing application written in Clojure
It is hard to say where the root of your problem lies without looking at the code more. I would look closely at laziness. I find that lazy evaluation really kills parallelization.

Re: gemacl: Scientific computing application written in Clojure
Sounds like some form of overhead is dominating the computation. How are the infinite sequences being consumed? Is it 1 thread per sequence? How compute-intensive is (move particle) ? What kind of numbers of are talking about in terms of steps, particles? If move is fast, you probably need to batch up your computation. If move is a simple arithmetic operation or otherwise something without an inner loop, I'd make it perform at least 100 iterations per invocation. If you have many particles, I'd pay attention to how the threads are switching between them, and eliminate any switching if possible. I'd definitely recommend removing the global recording to reduce complexity for now. On Fri, Nov 8, 2013 at 4:42 PM, Jose M.

Re: Do (should?) these core.async utilities exist?
Hi Paul, Two different reasons: The channel-to-sequence conversion seems like a questionable idea, making seqs that block.

Re: Step by step debugging
Sounds like a fun project, but probably non-trivial. Too bad... unless someone wants to have that fun and then share it with the rest of us :-) I have started a project that does this: a browser based debugger that breaks on exceptions (it attaches to a dt_socket port): https://github.com/prismofeverything/schmetterling I should have locals displaying this week sometime (you can currently get their value, it just doesn't show them to you by default yet). I am planning on adding breakpoints, stepping and source viewing. Just started this... looking for feedback!

Releasing Caribou today: Open Source Clojure Web Ecosystem
Hello Clojure, Excited to announce today the release of Caribou! http://let-caribou.in/ We have been building web sites and web applications with it for over two years now and improving it every day. Currently we have four people working on it and another ten using it to build things, so it is getting a lot of real world testing. It has been designed as a collection of independent libraries that could each be useful on their own, but which come together as a meaningful whole. We have been spending the last couple months getting it ready for a full open source release, and I am happy to say it is finally ready. Funded and supported by Instrument in Portland, OR: http://weareinstrument.com/ We have four projects using it in production, and several more about to be launched (as well as over a dozen internal things). Documentation is here: http://caribou.github.io/caribou/docs/outline.html Source is here: http://github.com/caribou/caribou (use this for issues, you don't actually need the source as it is installed through a lein template). Some of the independently useful libraries Caribou is built on are: * Polaris -- Routing with data (not macros) and reverse routing! : https://github.com/caribou/polaris * Lichen -- Image resizing to and from s3 or on disk: https://github.com/caribou/lichen * Schmetterling -- Debugging Clojure processes from the browser: https://github.com/prismofeverything/schmetterling * Antlers -- Useful extensions to mustache templating (helpers and blocks, among other things): https://github.com/caribou/antlers * Groundhog -- Replay http requests: https://github.com/noisesmith/groundhog And many others. Basically this is an Alpha release, and I am announcing it here first in order to get as much feedback from the community as possible. We have made it as useful as we can for our purposes and recognize that for it to improve from here, we really need as many people using it and building things with it as possible. The documentation also needs to be put through its paces: we need to see how well people are able to use it who know nothing about it, based only on the existing docs. All feedback welcome! Thanks for reading! I hope you find it useful. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Do (should?) these core.async utilities exist?
I think the whole idea is event-driven and async.

I'd be grateful for pointers if any of these do exist and I'm just missing them, or suggestions for reasons why I don't really want them and should be tackling the problem in a different way: - A way to convert a channel to a lazy sequence (i.e. build the sequence by repeatedly reading from a channel until it's closed). It seems odd that core.async provides a means to turn a lazy sequence into a channel (to-chan) but not the inverse? - An equivalent of doseq for a channel, which repeatedly reads from the channel and calls its body with the result of doing so, terminating when the channel is closed.

Re: SuperShuttle sharing, 7 pm 11/13 from IAD?
So far, it's just two of us (Juan Martin Facorro and me), but we'd be happy to have others join in. Here's some contact information: Juan: Virgin (VX) 84, getting in (nominally) at 5:30 pm Rich: UNITED (UA) 727, getting in (nominally) at 6:39 pm Juan and I will meet at the Washington Flyer Shared Van kiosk (on the Ground Transportation level). There are two of these, so we'll meet at the one near the low-numbered baggage areas (eg, 4). We're taking SuperShuttle straight to the Alexandria Embassy Suites. My cell number is +1 650-291-8332. Calling it won't do much good until I land, but SMS might work well... Juan's cell number is (+54 11) 53769362 (where 54 is Argentina's code and 11 is the Buenos Aires' code). Once Juan and I meet up (about 7 pm), we'll be ready to check in and get on a shuttle. So, be there or be elsewhere... -r On Nov 11, 2013, at 18:18, Rich Morin wrote: Does anyone want to split a SuperShuttle ticket from IAD to the Embassy Suites in Alexandria, VA, about 7 pm on 11/13?

Re: Step by step debugging
Colin (or anyone), for a Clojure newbie, could you spell out what you're saying about *compiler-options* and -Dblahblah a little bit further? I think you're saying that if *compiler-options* is set to :disable-locals-clearing , then values of local variables are available, somehow. Can I see them from the lein REPL, somehow? If not, what do I get from :disable-locals-clearing ? It also sounds as if the only way to set *compiler-options* to :disable-locals-clearing is to use -Dclojure.compile.disable-locals-clearing=true . Where would I put that in a Leiningen project file?

Re: Releasing Caribou today: Open Source Clojure Web Ecosystem
Prasanna, It supports Ring as well. You should be able to just lein ring server in the root of your new project and it will boot up. The ring options are in the project.clj so you can change the port etc. It also supports Immutant, Tomcat, HTTPKit, Heroku and Beanstalk. If you know of another good target let me know and we'll support that too! As for NoSQL, a lot of the Model and Association stuff in Caribou is naturally relational, but all of the db interactions are abstracted by a DbAdapter protocol, so we (or someone) would just have to write an adapter for it. Maybe some of the Association stuff would be trickier, but there's no reason it couldn't be done. We are planning to support many more backends in the future, but for now it just supports Postgres, Mysql and H2. There has been talk of supporting Datomic as well, we will see what the future holds. All that said, there is no reason why you couldn't put a NoSQL db in front of the various model queries right now as a kind of caching layer. As a primary data store, that would take some work. I will see how much interest there is! On Tuesday, November 12, 2013 9:19:27 PM UTC-8, Prasanna Gautam wrote: This is really cool. Very easy to get up and running for first try.

Re: Releasing Caribou today: Open Source Clojure Web Ecosystem
Justin, As far as I know, Immutant is not a dependency, but an option. Let me know if that is not true however.

Re: Do (should?) these core.async utilities exist?
Hi Paul, I have implemented at least the doseq equivalent in a library of my own called state-node: https://github.com/lgrapenthin/state-node. It implements gochan and gochan-and. gochan lets you bind a binding-form to a channel but also lets you recur (if you bind things aside from the channel). It terminates the loop when the channel is closed. With gochan-and you can specify one form that will be evaluated after the channel is closed (e. g. close a target channel). E. g.: (gochan-and (close! out-chan) [taken-val in-chan] (println Value read from in-chan: taken-val) (! out-chan taken-val)) Please feel free to copy the macro directly from the library if you have any use for it :) Maybe also have a look at reducep-hidden (adapted from hidden automatons from ELM) which kinda lets you do the same if you aren't going for side-effects or custom looping conditions. One problem with the lazy-sequence thing would be that such sequences would only work in go-blocks if I my thinking is right this morning. Best regards, Leon.

I'd be grateful for pointers if any of these do exist and I'm just missing them, or suggestions for reasons why I don't really want them and should be tackling the problem in a different way: - A way to convert a channel to a lazy sequence (i.e. build the sequence by repeatedly reading from a channel until it's closed). It seems odd that core.async provides a means to turn a lazy sequence into a channel (to-chan) but not the inverse? - An equivalent of doseq for a channel, which repeatedly reads from the channel and calls its body with the result of doing so, terminating when the channel is closed. Of course, both of these are easy enough to write, but I'm wondering whether the fact that they aren't provided as standard is telling me something? -- paul.butcher-msgCount++ Silverstone, Brands Hatch, Donington Park...

[ANN] Troncle: Emacs convenience functions for tracing clojure code
troncle Troncle https://github.com/coventry/troncle is a proof-of-concept integration of clojure's tracing tools with emacs, built around technomancy's innovative nrepl-discoverhttps://github.com/technomancy/nrepl-discover and a robust (very simple) code-walking/wrapping macrohttps://github.com/coventry/troncle/blob/master/src/troncle/macroshka.clj I've developed. It's available for download at https://github.com/coventry/troncle clojure.tools.trace is super-handy for exploring how code is executing, but wrapping and unwrapping subforms with (ctt/trace ...) gets tedious. The main idea with troncle is to take most of that tedium away by letting you use emacs to point at the forms you want to wrap and then doing the wrapping for you automatically during compilation. In the end, I hope to turn this into a stepping debugger, in the spirit of elisp's edebughttp://www.gnu.org/software/emacs/manual/html_node/elisp/Edebug.html . This release is a very rough first cut, which I've published mostly because I'm hoping to talk to people at the Clojure Conj about what directions to take it in. If this seems like an interesting project to you, please take a look at the roadmap https://github.com/coventry/troncle#roadmap and let me know what you think. (Whether you're at the Conj or not, of course.) If it seems useless or otherwise misguided, please also let me know what you think. :-) All feedback is welcome. https://github.com/coventry/troncle#usageUsage Currently, troncle has one function: You mark a region of your code, hitM-x troncle-trace-region(C-c t R), and troncle sends the top-level defun containing point to clojure for compilation. Any forms contained in the marked region, as well as any forms generated by their macroexpansion, are wrapped in a call to clojure.tools.trace/trace so that the results of their evaluation during execution are reported in the repl buffer. In order to do this, you have to let troncle know how to execute the code it's compiled. You tell it using the function troncle.traces/st (for set test.) For instance, suppose that you have the following code in tst.clj open in emacs and have selected the cyan region: (ns troncle.tst) (defn ^String capitalize [^CharSequence s] (let [s (.toString s)] (if ( (count s) 2) (.toUpperCase s) (str (.toUpperCase (subs s 0 1)) (.toLowerCase (subs s 1)) After installing https://github.com/coventry/troncle#installation troncle and compiling this file with C-c C-k, type the following into the nrepl buffer to tell troncle how you want to test this function: user (troncle.traces/st #(println (troncle.tst/capitalize foo))) Now go to the tst.clj buffer, and highlight the region with the cyan background shown above. TypeC-c t R, and the following should appear in the nrepl buffer: TRACE [4 11] (.toString s): fooTRACE [5 12] (count s): 3TRACE [5 9] ( (count s) 2): falseFoo [4 11] gives the line/column position of the form (.toString s) in the buffer.foo` is the result of its evaluation. Only three forms are traced, because those are the only forms in the selected region. https://github.com/coventry/troncle#installationRoadmaphttps://github.com/coventry/troncle#extended-functionalityExtended functionality This is a very simple application at the moment, but I think it has a lot of potential. The core functionality is introncle.macroshka, which is a very robust code-walking scheme. (I've run it over the entire clojure source code.) These are the directions I'd like to move it in: 1. Emacs convenience functions for passing load this file and run this test functions totronce.traces/st. 2. Tracing instrumentation for multiple regions within a top-level form. 3. Filtered tracing: Only report a trace when a given predicate returns true. Predicate can be specified in terms of return values of the forms under consideration. 4. Save and restore current tracing configuration. 5. Tracing of bindings to local variables. 6. Send trace reports to a clojure list, rather than/as well as the repl, so that they can be queried programmatically. 7. Replay a series of trace reports using emacs overlays (nrepl-discover's overlay facility should make this easy.) 8. Replace the tracing with source-level step debugging.
