hmm, try me, but that's changed a bit since I was deeply familiar
<weeb1e>
I just started looking at the source, and I presume starting a transaction for each update query delays setting the attribute with the setter method until the transaction has started
<weeb1e>
Which would explain a bunch of my race conditionms
<weeb1e>
*conditions
mansi has quit [Remote host closed the connection]

I basically want to patch it to set those attributes on the model instance before even starting the transaction, since being the only single threaded application accessing the database, transactions will never fail

Firstly I'm presuming with_transaction_returning_status starts a transaction, which delays assign_attributes until the database responds
mary5030 has joined #ruby
<weeb1e>
Which means that another fiber that checks the attribute between an update being called, and the transaction starting does not see the attribute as been set yet
mansi has quit [Ping timeout: 248 seconds]
<weeb1e>
The instance of the model is cached and read from without a query, so I want the attribute set instantly, without any delay
<rjhunter>
gotcha
i8igmac has quit [Quit: Leaving]

Maybe it would make more sense to just disable transactions completely?

Flashmasterson1, it's just that most people think you should know a bit about the command line before programming ruby

so you know the folder the code is in, don't add the ~, cd to it, run the command you need to run
<jrobeson>
that is.. you're a step too deep atm

is that an rvm setting or extension of some sort?

one day I'll find something that zsh helps me with

ctrl-r history in zsh is much better out of the box, tab completion of files and directories is better tuned to the application you're using. It's nice that it can implement fish shell features while still maintaining sh compatibility.

MySQL seems to become pretty slow as a basic select query filtering within a created_at range with 1.6 million records in a table
<weeb1e>
I wonder what will happen when it reaches a few million
<jrobeson>
and your indexing is good?

<weeb1e>
This is the only legacy platform of mine that uses MySQL, all my other platforms are strictly MongoDB
<jrobeson>
no, fields that you query by should be, but only an EXPLAIN will tell lyou the right way
<weeb1e>
Well that's what I mean
<weeb1e>
All fields that are used in the WHERE part of queries
<weeb1e>
I should add created_at to the indexed fields in that case

Surely explain only helps you see what indexes are being used and how many rows there are to check, which means you still have to add indexes before using explain?

I have a test set up to see if the method works. two string (hex-ed) xored together should produce a third, which I know is correct. your solution prints false. the only one that prints true is the one with the to_i(16) conversions...

a change in ruby 2.0 has highlighted a design flaw in something i wrote, but i'm unsure of how to fix it, i have a process that upon receiving a USR1 signal, kills child processes, forks and loads a new version of the child process, unfortunately since ruby 2.0 it's illegal to call require inside a trap, since my fork was inside a trap, my entire child process ends up being inside the trap

hey.
<robert_>
so I'm looking at writing a ruby SOAP/WSDL server, however I'm getting "undefined method `upcase' for nil:NilClass (NoMethodError)" when I try to access the server from .NET :/
<Morrolan>
Well, somewhere in your code (the stacktrace will tell you where) you're calling 'upcase' on an object which happens to be 'nil'.

mantas322, line 11: create a new object, contents '15', and create a new reference to it, called 'a'. line 14: create a copy of that reference (so there are two references to the object '15'), and pass that to 'something'. line 2, create a new object '12', assign that to something's 'a' reference, leaving the one created on line 11 pointing to the old '15' object

same with 'b', *except* that on line 7, we mutate the object pointed to by somethingelse's 'b', rather than creating a new one. the 'b' from line 12 still point to that object, so line 21 prints the mutated one

not the best explanation, but hopefully you get the drift
<mantas322>
I get it .map! mutates the original object
francisfish has joined #ruby
<canton7>
'a = a.map...' would not mutate the original object

pilotte: Though looks like you're using apt Ruby, so i guess just: sudo apt-get install -y ruby1.9.1-full
<havenwood>
pilotte: Switch to chruby or rvm when the apt packaged Ruby drives you mad. :P

what do chruby or rbenv do that rvm doesn't ? I've never had any problems with it ...

in Ruby 2.0, how can I encode a degree sign (ASCII 176) from unicode string to ASCII-8BIT? "\u00B0".encode("ASCII-8BIT") gives "UndefinedConversionError: U+00B0 from UTF-8 to ASCII-8BIT"

what they call 'Extended ASCII Codes' could be codepage 437, aka 'IBM437' in ruby. not sure though, I didn't go around comparing all characters.
