I'd first try increasing the connection pool size and see if that affects things. That should tell you if the issue is an issue with blocked connections. On Sat, 19 Jan 2019 at 21:25, wrote: > I'm looking for advice about how to debug this. > > I wrote a small web app. It has about 1,200 lines o

How should I debug a poorly performing small web app, using Jetty?

I'm looking for advice about how to debug this. I wrote a small web app. It has about 1,200 lines of code. It is fairly standard for a Clojure app, it uses Jetty, and Compojure. It uses MongoDB. I'm just working on my MacBook Pro right now, so there is no issue such as using Nginx or load bala

Re: Learn Clojure - Syntax Test your knowledge No4. question.

If in a Clojure REPL session you type `(doc find-doc)`, you should see this (I'm using Clojure 1.10 here, in case the doc string has changed in a recent Clojure version): ser=> (doc find-doc) - clojure.repl/find-doc ([re-string-or-pattern]) Prints documentation for any va

Re: Any way to replace function body?

dispacio has a shadow-extend-like capability: (defp assoc string? [s i c] (str (subs s 0 i) c (subs s (inc i And then (assoc "abc" 2 'x);#_=> "abx" Using alter-var-root in dispacio correctly would prevent var replacement warnings I

Yes, the alter-var-root function allows you to change a var's definition: (alter-var-root #'fetch-data (fn [original-fetch-data] (fn [& args] (let [result (apply original-fetch-data args)] (transform-result result)) On Sat, 19 Jan 2019 at 14:58, Janko Muzykant wr

Re: Any way to replace function body?

There has to be. Trace, profile, and debugging libraries for clojure do it all the time. I might check the source for some of those. On Sat, Jan 19, 2019 at 9:06 AM jason poage wrote: > Why would you want to overwrite a function if you need reference to the > original function? Why not just re

Re: Any way to replace function body?

Why would you want to overwrite a function if you need reference to the original function? Why not just rename the wrapper function to something else? Or you could use (source function-name) to get the function body and essentially rename the function. Sent from my iPhone > On Jan 19, 2019, at

Checkout multi-arity functions in clojure. On Sat, 19 Jan 2019 at 8:28 PM, Janko Muzykant wrote: > Hi, > > Is there an way to replace body of existing (interned) function with own > code still being able to call original fn? > Suppose, I have a function: > > (defn fetch-data [arg1 arg2] >

Any way to replace function body?

Hi, Is there an way to replace body of existing (interned) function with own code still being able to call original fn? Suppose, I have a function: (defn fetch-data [arg1 arg2] (db/fetch-data ...)) I would like to intern a slightly modified version of this fn. Something like this:
