Re: [ANN] Clojure 1.8.0-RC2

[Alex Miller]

Hey Serzh,

Rich just pushed a change to master that removes unused interns in the 
static initializers - we are doing some further testing on it before 
creating an RC but if you wanted to check it out as a snapshot, I'd be 
interested in hearing your feedback in particular as you have a specific 
need for it. 

You can see info on how to use a snapshot build of Clojure here (you need 
to add the snapshot Maven repository):

Hi Serzh,

Re: [ANN] Clojure 1.8.0-RC2

[Serzh Nechyporchuk]

Hello, Alex. Thank you for your work.

Direct linking is a feature that we wait for a long. We need to obfuscate 
our code, so direct linking is really helps us.
But I wonder, why there is keyword and symbols interning left in the static 
initalizer in the class:

L1 {
 ldc "clojure.core" (java.lang.String)
 ldc "float?" (java.lang.String)
 invokestatic clojure/lang/RT 
var((Ljava/lang/String;Ljava/lang/String;)Lclojure/lang/Var;);
 checkcast clojure/lang/Var
 putstatic malt/utils$string_to_double.const__0:clojure.lang.Var
 ...
}

But neither *invoke* nor *invokeStatic *doesn't use them.
We want to get rid of this interns because they undermine code obfuscation.

Thank you

Re: [ANN] Clojure 1.8.0-RC2

[Ambrose Bonnaire-Sergeant]

I'm missing something, alter-var-root'ing *clojure-version* works just fine
when calling (clojure-version).

(alter-var-root #'*clojure-version* assoc :qualifier "patched")
(clojure-version)
;=> "1.8.0-patched"

Thanks,
Ambrose

I see the same and I suspect it's because of the forward declare.  :(

Thanks.

Here's a good test, feel free to use it.

(deftest direct-linking-for-load
  (let [original-load load
called? (atom nil)
logger (fn [& args]
 (reset! called? true)
 nil)]
(with-redefs [load logger]
  ;; doesn't actually load clojure.repl, but should
  ;; eventually call `load` and reset called?.
  (require 'clojure.repl :reload))
(is @called?)))

Thanks,
Ambrose

I reopened the ticket. You can hold on the patch - I think we're going to 
make another change that will affect what the patch will be.

 I was expected "patched" to be printed with each call to `load` via

 Do others observe this also?

Re: [ANN] Clojure 1.8.0-RC2

[Ambrose Bonnaire-Sergeant]

I don't think CLJ-1845  had
the intended effect.

user=> (alter-var-root #'load (fn [f] (fn [& args] (prn "patched") (apply f
args
#object[user$eval1241$fn__1242$fn__1243 0x1c857e6
"user$eval1241$fn__1242$fn__1243@1c857e6"]
user=> (load)
"patched"
nil
user=> (require 'clojure.core :reload)
nil
user=> (require 'clojure.tools.analyzer :reload)
nil
user=> (require 'clojure.tools.analyzer :reload-all)
nil

I was expected "patched" to be printed with each call to `load` via
`require`.

Do others observe this also?

Thanks,
Ambrose

[ANN] Clojure 1.8.0-RC2

[Alex Miller]

Clojure 1.8.0-RC2 is now available. *This build is a "release candidate"!* We 
would appreciate any and all testing you can do on your own libraries or 
internal projects to find problems. 

Try it via

   - Download: https://repo1.maven.org/maven2/org/clojure/clojure/1.8.0-RC2
   - Leiningen: [org.clojure/clojure "1.8.0-RC2"]

Below are the changes since 1.8.0-RC1. See the full 1.8 change log here: 
https://github.com/clojure/clojure/blob/master/changes.md.

   - CLJ-1846  Fix VerifyError 
   when primitive type hints are incorrect. These cases now throw compiler 
   errors.
  - Example: (defn foo ^long [] 1)  (Integer/bitCount ^int (foo))
  - In this example, foo returns a long but is type hinted 
  (incorrectly) as an int. This case will now throw a compilation error. 
The 
  correct way to do this is with a cast:  (Integer/bitCount (int (foo)))
   - CLJ-1825  Fix compilation 
   errors on direct linking of anonymous recursive functions
