Re: Stuart Sierra's Component: retries & restarts in production

I'm using components to encapsulate Langohr/RabbitMQ interactions in cases where Langohr auto-recovery wasn't happy with what was going on. I make sure the Lifecycle methods are idempotent, built the component stack in the correct order. To make sure that I can deal with the exceptions that

Re: Stuart Sierra's Component: retries & restarts in production

Caveat: my approach may have been all wrong. It's the first time I tried stuartsierra components. Frankly I'd have been happier with some CLOS objects and before and after methods, I'm still getting the hang of this clojure stuff. On Fri, Sep 4, 2015 at 7:57 AM, Dave Tenny

Ok, so to give myself a safe and consistent way to reason about this the addition operator, and probably other arithmetic operator dont promote ouput so long+ long = long or exception long + bigint = bigint if i need outpout promition i can use +' hmmm, a bit tricky On Friday, September 4,

supporting metadata caret reader syntax with deftype

I have a deftype that supports with-meta, but I can't figure out how to support caret reader syntax. To support with-meta, I include a "meta" field and implement IObj methods "meta" and "withMeta". Seems to work just fine: (with-meta (entity-map [:A/B] {:a 1}) {:foo "metadata here"}) But

Re: Stuart Sierra's Component: retries & restarts in production

We make sure the components we build know how to restart themselves. This avoids the use of start/stop. -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email to clojure@googlegroups.com Note that posts from new members

I've now finished an initial draft of AA Tree Map and it passes collection-check: (deftest tests (assert-map-like (create-aamap) gen-element gen-element ; {:base (sorted-map) :ordered? true} )) Unfortunately I had to comment

Re: some guidance sought

Fixed. I left out the n argument, which is not optional when specifying options: (deftest tests (assert-map-like 100 (create-aamap) gen-element gen-element {:base (sorted-map) :ordered? true})) Runs great. :-) On Friday, September 4, 2015 at 2:29:49 PM UTC-4, William la Forge

You can use *unchecked-math* if you want unchecked arithmetic behaviour: => (set! *unchecked-math* true) true => (+ Long/MAX_VALUE Long/MAX_VALUE) -2 On Friday, 4 September 2015 23:04:27 UTC+8, Ali M wrote: > > Ok, so to give myself a safe and consistent way to reason about this > the addition

Re: supporting metadata caret reader syntax with deftype

This has came up numerous times in other posts here. I can't hunt them down currently but the quoted symbol issue you showed is just a misunderstanding of how the reader macro for metadata works. Try (meta '^{:foo :bar} a) When you put the reader macro in front of the quote it is applied to
