Re: for everyone who complete the ruby on rails tutorial by M. hartl

[John McCaffrey]

Are you missing some css or something?

I would look in dev-tools in the browser to see if there are any errors.
Areas to investigate:
1. Are there any files that did not get checked in?
2. Are there any css/js files that did not get properly handled by the
asset pipeline?
3. Are there any errors in the browser? (does it render differently in
different browsers?)
4. Are there any errors in the heroku logs?


You might find that others have run into this same issue and posted

Re: 400 Bad Request When Sending Post Request

[John McCaffrey]

If you look at the logs do you see a difference in what you are sending in
when it works from the form vs server post?

Is it because of the security token (the hidden form value rails adds to
forms)

Re: Watir on heroku

[John McCaffrey]

I've never combined multiple buildpacks, but it is possible

https://github.com/ddollar/heroku-buildpack-multi

let us know how it works out!
I think there are others that want to use a scraper like phantomjs, and a
website in the same app.

Re: Watir on heroku

[John McCaffrey]

I like using phantomjs for scraping, though I haven't used it on heroku yet.

I see there is a buildpack
https://github.com/stomita/heroku-buildpack-phantomjs

this example might be helpful

Re: Headless Processing on Heroku

[John McCaffrey]

I use phantomJs to login/scrape data from a site, then I put that data in a
db.

It runs a full browser, with javascript events, ajax, etc.

1. login to a secure site, navigate to a list of orders
2. pull down data for each order and write it to a file
3. process each file and write to the database.

I use phantom for step 1 and step 2, and have multiple workers executing at
the same time (because of I/O and network delays)

I have a separate ruby process that picks up the new files and does the
processing. (and I can fire up multiple workers of this type if I need to)

CasperJs  is a nice addition that can make writing
your scripts even easier

Re: Issue with Google indexing caused by herokuapp domain

[John McCaffrey]

when I click or enter the naked/root domain dogiamsf.com, it resolves to
http://dogiamsf.herokuapp.com/ in the browser, so it makes sense that
google is seeing the same thing.

You probably just need to review your dns setup and double check everything
according to the docs for how to set up Root domains.

https://devcenter.heroku.com/articles/custom-domains

> host dogiamsf.com
dogiamsf.com has address 184.168.221.23
dogiamsf.com has address 75.101.145.87
dogiamsf.com has address 75.101.163.44
dogiamsf.com has address 174.129.212.2
dogiamsf.com mail is handled by 0 smtp.secureserver.net.
dogiamsf.com mail is handled by 10 mailstore1.secureserver.net.

> host  www.dogiamsf.com
www.dogiamsf.com is an alias for dogiamsf.herokuapp.com.
dogiamsf.herokuapp.com has address 50.17.218.27

Re: Search form works on local machine, but not on heroku!

[John McCaffrey]

Do you think it is the acts_as_indexed gem, and how it writes to the
filesystem?

https://github.com/dougal/acts_as_indexed/issues/29

try taking that out and see if you still get the error. It seems like a
good place to start (or any gem that does something outside of the heroku
norm)

Re: PDTFTK on Cedar stack

[John McCaffrey]

Thanks for sharing the info!

I figured that someone would have a public buildpack of pdftk, and figured
this out already.

I imagine you saw this:
http://stackoverflow.com/questions/7128855/statically-compile-pdftk-for-heroku-need-to-split-pdf-into-single-page-files


I have an app that is hosted on rackspace, but I have staging and qa
servers set up on heroku, so I can demo changes to my client prior to
pushing to prod. Right now I just disable the pdf functions in those
environments, but I'd really like to get it working.

Re: Heroku plugin for bug-tracking / code-review

[John McCaffrey]

There are other places besides github to host your code, if you are open to
them. (and it doesn't annoy the team to be on something else).

https://bitbucket.org has free private git repos, which might be worth a
quick look (free for up to 5 people).

Re: Diagnosing outage

Also, its good to follow @herokustatus on twitter

The new relic add-on has a ping feature which is useful.

The StillAlive add-on goes a bit further with a full functional test (but

Re: postgres query help

[John McCaffrey]

I would try to reproduce it locally, and see which index combinations are
best (pull down prod data if you can).

You can also run the explain from the heroku console, to get feedback about
how the postgres query planner is looking up the data.

Most likely you need to add an index on lastreport, if that index should
really only contain entries for the last 90 days (or whatever your interval
is), you can also use a special postgres feature called a partial index.
(the index only contains entries that match a constraint, like lastreport >
'01-01-2012', and can really speed things up. you update that index every
month or whatever to drop off stuff that isn't relevant)

The planner will tell you if it is able to combine your existing individual
indexes to get all the data it needs. If you always query these columns, it
might be better to do a single index, but you'll have to test that and see.
(which I think is just a lot easier to do locally)

Re: confused about best practices for CNAME records

[John McCaffrey]

I don't think of it as heroku suggesting that you have to do it with a
CNAME, but Neil's post highlights why you might want to.
 
http://neilmiddleton.com/the-**dangers-of-a-records-and-**heroku

I think of it like apple including their 'time machine' backup software
means you'd buy a backup drive. They aren't saying you absolutely have to
do it, but its a good idea for a variety of reasons.

You can use an A record and the ip addresses, it will work fine, but if
there is an outage and they have to bring your app up on other IPs, you'll
at least have a heads up for what you can do about it.

Personally I like dnsimple.com, so I don't think of it as an extra thing I
have to do, but as an extra reason I like their service, like they are
helping me manage my app in a way that stays current with hosting on a
cloud solution like heroku, openshift, cloudbees, etc.

Re: Assets Precompile: Works Locally, Heroku Skips Some Files

[John McCaffrey]

thanks for posting the resolution!

I did not know about that difference in behavior for the .slugignore file
(that's going in my notes).

I also have not played around with making a buildpack yet, so my note on
that is "you can create a custom buildpack to help you debug issues".

Actually, if you don't mind pushing that verbose buildpack out to github,
I'd love to check it out, and see how it works.

I've been helping students with a variety of technical backgrounds with
their heroku deployments, and sometimes they get themselves into some
interesting situations that are not easy to tease out at first, and having
a verbose buildpack like this might really cut down on the amount of time
spent trying to 'guess' at what the issue is.

Also, I wonder what questions we could have asked you that would have lead
us to your .slugignore situation.

"Do you have any other projects using these tools that are working ok?"
Followed by "What is different about this project vs. those?"

"If you create a new project from scratch, using the same versions of these
tools, do you have the same problem?"

Thanks again for posting the outcome, its enormously valuable for the rest
of us.

 However, the same project when pushed to Heroku skips some of the asset
 files. Just so I'm clear, these assets files are specified using
 'config.assets.precompile += []'. Here is the exact code in production.rb:


   config.assets.precompile += [ 'print.css',

 'not_auto_loaded/installation.**js',

 Print.css, api_docs.css, installation.js, and token_recover.js compile
 just fine and asset sync sends them on their merry way to S3. But *
 nothing* I have tried over the past two days will get
 unauth_web_connect.js or tester.js to compile on heroku. No errors are
 reported during slug compilation or in the logs.

 Token_recovery.js.coffee and installation.js.coffee compile just fine,
 and appear on S3 as expected, digests and all.

 Unauth_web_connect.js is a coffeescript file
 (unauth_web_connect.js.coffee) that resides in '
 app/assets/javascript/not_**auto_loaded/'.

 I have tried, and it did not fix:

- changing the names of the xxx.js.coffee files
- reducing the javascript in xxx.js.coffee files down to just
'alert "home"'
- changing the order in config.assets.precompile
- removing the xxx.js.coffee file and re-creating it

 I'm out of ideas.

To rule out a heroku specific issue, try running locally in production
mode. This usually reveals an issue.

if not, then try

Re: Keeping your Heroku app awake

[John McCaffrey]

I think this is a good discussion to have, in terms of appropriate use of
'free resources' to keep the plan sustainable, and "reasonable pricing for
the 'little guy'" with tons of small apps that don't get daily usage.

Those topics are important, but not something that will be resolved any
time soon, the more tractable computing problem is how to best optimize a
site on the free plan, so as to minimize the impact of spinning up a dyno.

A few strategies:
1. use browser and http caching for as much as you can
2. use a cdn like cloudflare.com or others
3. reduce dependencies for your app?
4. figure out what is slow, and how to improve it

I'm not really sure what is happening in the spin up of a dyno, and what I
could do to make it better. I just hit an idle app of mine and looked in
the logs to see what it was doing.

So if I'm reading this right, a request came in at 18:22:35, and woke up
the dyno, and that request passed through to the app at 18:22:56, meaning
there was about a 21 second delay.

There seems to be some time in between each
" Cannot find or read /app/config/newrelic.yml"
I wonder if putting that config in there would make the spin up faster?

I'm also spinning up 4 unicorn workers, would it be faster to start with
only 1 or 2, and then add the others later (is that something that
could/should be done programmatically?)

I'm curious what other people are seeing for dyno spin up times, and any
strategies for making things go faster. (Wonder if I'm including any gems
that are not needed in prod, and if that has an impact)

Run heroku logs for one of your idled dynos, then hit the url and see how
long it takes, is there a lot of variation? (bamboo vs cedar, thin vs.
unicorn, rails vs. sinatra, etc)

Re: Keeping your Heroku app awake

[John McCaffrey]

Once you pay for a dyno, its up all the time, so this strategy is only
necessary when you are not yet paying to host your site on heroku.

So I think it makes sense to take the idea of "ping the server every X
min", and add a bit more to the logic of asserting that the response is
correct and timely. Implementing even a basic strategy for monitoring your
application's uptime, performance, and consistent functionality is an
important component in how you manage your site, and there are a variety of
tools out there that can help.

New relic can ping your app and alert you when it is not responding and
passing your assertion test. (specific words on a page)

You can have a simple ping and report from http://www.internetvista.com

BrowserMob.com and others can do multistep flows like logging in and
navigating to a page.

StillAlive.com and the heroku add on is great for defining a full
cucumber-like test suite to ensure that not only is your site up, but it is
still functional.

But I hope that people use some restraint when deciding which of their apps
they want to 'artificially keep awake', and find a nice balance that uses
resources wisely.

Using the free plan on cloudflare.com CDN might be useful, particularly if
your main pages and most of the assets can be cached. (the page will load
quickly in the browser, from the cdn, then fire an uncacheable request to
wake up the server, without the user feeling like its slow).

Actually using cloudflare is a win-win even after you're off the free
heroku plan, because it allows you to handle more concurrent users and load
things faster.

Re: Heroku Labs git_submodules private repos

[John McCaffrey]

can you move your config variables out of the submodule, and load them via
heroku config?

Getting important authentication params out of a repo is usually one of the
first things you have to do after a security analysis, so you may as well
just do it now.

Re: retrieve an old slug..?

[John McCaffrey]

If you committed your sqlite db locally, it might be in your git repo.
If you have db backups on, you might be able to restore from a previous
deployment

Re: Pure cloud publishing workflow GitHub/BitBucket <-> Heroku?

[John McCaffrey]

I tried cloud9 IDE and was able to make changes and push directly to
heroku. I found it very cool as an emergency "I'm not at my machine, but
need to make a quick fix" tool, but not something I'd want to do as part of
my regular dev cycle. (yes, even with the concept of pushing to a staging
server first. I'd still prefer to run and test things locally, but that's
just me)

Re: When pushing to Heroku it crashes on Installing do_sqlite3 (0.10.7)

[John McCaffrey]

You may want to just skip ahead and set up postgres locally, so that your
dev environment is as close to heroku as possible.

34% of problems that people have when starting with Heroku are due entirely
to not running postgres locally**
And when the problems do come up, its usually in a non-obvious, total pain
in the ass way

**This statistic is totally made up, but feels about right, given this
mailing list, StackOverflow, and other people I've helped get set up on
Heroku. Maybe a more accurate number would be 34% of the issues I've dealt
with when helping people get set up...

Re: Very simple line is not working on heroku but is fine locally

[John McCaffrey]

Is there anything special about the hierarchy for that class? is it related
to any plugins?

Are there other classes that you can't instantiate? Is there a commonality
among them? (if its just this one, is there something special about it? can
you strip out that difference and try again?)

I saw a similar issue someone complained of, when loading a plugin that had
submodules. If this class is related to some other plugins or libraries,
see what is going on there. (and post back)

Re: heroku rake db:migrate - Internal Server Error

[John McCaffrey]

I used to just get 'internal server error' in the console when I had
various syntax issues, until i updated to the latest heroku gem, now I see
more useful info.

See if that helps your migration.

Does your migration work locally? Is it complex? (eg. doing something more
than just changing table def)

Re: Anyone else have a problem with status.heroku lack of information?`

[John McCaffrey]

Along those lines, is there a way to get alerts from heroku when there is
an issue? This last issue had my site down for a bit, but thankfully the
NewRelic alert let me know quickly, so I could get to work on routing to a
backup server.

Is there some heroku notification checkbox I missed somewhere?

Re: i can't able to deploy my database backup b004.dump file to my heroku app

[John McCaffrey]

Yeah I do a similar thing to back up my data from a production site to my
staging/test site.

on prod account
  # grab temp URL of the recent backup
  heroku pgbackups:url b016

on staging account
  # use that URL from above as source to restore from
  heroku pgbackups:restore DATABASE 'https://s3.amazonaws.com/'

but I also keep a sep copy of the backup, just in case.

Re: i can't able to deploy my database backup b004.dump file to my heroku app

[John McCaffrey]

Are you restoring a dump from the same app, or trying to move data from one
heroku app to another, or from a non-heroku app up to heroku?

did you try adding it from the heroku website?
wouldn't the command be heroku addons:add pgbackups:basic

if you've tried that, and still get account issues, is this the case when
adding other addons?

if b004 is the most recent, then heroku pgbackups:restore will default to it

Re: Can I issue a "heroku restart" from within my app that's running on Heroku?

[John McCaffrey]

Some of the 
posts<http://stackoverflow.com/questions/6510203/eoferror-when-issueing-http-requests-with-ruby>
mention
https, content-length, and redirects, so If you could track the urls that
cause the problem, that might be helpful. (you may have to track the url
BEFORE the one that gets the EOF)

If you could then fire the same request from the heroku console, or write a
little bit of code that you can invoke on heroku or locally to fire against
known 'bad' or 'good' urls, as a test case, it might help you get to a
solution faster.

Have you looked into faraday or httparty?

I'm not saying you should completely bail on the idea of doing an app
restart, I'm just wondering if you could also explore a more direct fix at
the same time.

Good luck!

Re: Can I issue a "heroku restart" from within my app that's running on Heroku?

[John McCaffrey]

Again, I would suggest that you try to find the real heart of the issue and
find ways to debug/instrument the code to figure out what is happening that
gets it stuck.

Maybe opening a ticket with the heroku team may help (maybe its something
they've seen, or they have a good suggestion for how to dig in to it). They
read the mailing list, but an actual support ticket may be the way to go
for you.

A solution where you restart your app just doesn't seem like it will scale
to me, unless you are firing it off like a cron/delayed job, that has a
natural restart flow. (would it make sense for the scraping part of the app
to be a background job?)

Re: Can I issue a "heroku restart" from within my app that's running on Heroku?

[John McCaffrey]

I'm interested in that as well, but if the answer ends up being 'no',
perhaps your app could just capture the current state (eg. what caused it)
and send out an alert.

when I've had problems in the past, I've been helped by
logging (logs --tail and the loggly add on)
new relic
exception notification
google analytics (see traffic patterns and urls)


If you see the pattern and can fix it, you won't need to do the restart
business.

Re: How do you tell which of your Heroku apps are which?

[John McCaffrey]

if you open up the git info for the locally cloned app, you can see when it
was updated.

When I met with some of the Heroku people at RailsConf, I asked if they
could add just a little notes field, and the date that the app was created
or updated last...but apparently they have bigger fish to fry.

I make it a habit now to keep track of what the apps are or change their
name as soon as I create them. (and deleting old projects that don't have
meaningful names or aren't loading anymore)

Clean up your old, unused heroku apps, it'll be easier to find what you're
looking for.

Re: What exactly is a dyno?

[John McCaffrey]

I don't know the specific type of process it is, but maybe we could figure
out what you are looking for a different way.

What will you do differently if you found out it was a daemon vs. a short
process?
Is there a concern you have about how one vs. the other would perform?

Bonus Points: Is there a test you could create to expose the underlying
issue you are trying to mitigate?

People on this list are very helpful, but if a question is looking for exact
answers, no one will step up and answer because they don't know for sure.

Give us some more details and I bet you'll find someone else that has the
info, or pursued the same idea.

Re: Permission Denied (publickey) Error

This just means that your ssh info is not set up correctly.

try:

heroku keys

to see if your ssh keys are setup properly. You may just have to go back
through the instructions on getting you ssh keys created and available to
heroku. (if the heroku docs don't help, try stackoverflow.com)

Re: Java apps

[John McCaffrey]

Also, isn't that how things are deployed on google app engine? (just push up
a war file)

 It would be nice if the deployment process was similar, so that users of
other hosting systems could easily give heroku a try, and see how awesome it
is.

You may also want to checkout CloudFoundry  and
keep an eye on how they do things. (I just pushed out a rails app to their
beta product, and ran some performance tests. They are still adding
features, but my app is running fine, so I'll definitely keep them on my
radar)

Re: rack 1.3.2 conflict on bamboo

[John McCaffrey]

ok, so after reading through everything I could find on this, I determined
the following:

   1. While I have all my gems specified by bundler, I had a .gems file,
   which until today wasn't causing any issues, but once I removed it, and
   ensured that heroku was loading my gem properly, it was all good.

rack 1.3.2 conflict on bamboo

[John McCaffrey]

I redeployed an app today, and started getting a "You have already activated
rack 1.3.2, but your Gemfile requires rack 1.2.3. Consider using bundle
exec. (Gem::LoadError)"

I have a rails 3.0.3 app, and according to my Gemfile

  rack (~> 1.2.1)

I looked back at my Gemfile.lock, between these deployments, and rack has
been set to 1.2.1 the whole time.

Did something change?  is there a way to execute a bundle exec command on
the bamboo stack (I know you can on cedar, but I'm in the middle of pushing

I'd be curious if you can run the http://tryruby.org/ app on heroku, or

Re: Latency of writing in the DB

[John McCaffrey]

I would pull your prod data down locally and play with the queries to
optimize them in your local postgres. (rule out any difference in behavior
on the heroku stack)

grab your explain output and throw it in http://explain.depesz.com/

if your conditions are easy, you can add a uniqueness constraint at the db
level, which would be faster than doing it at the ORM/application level.

How to get New Relic 'Real User Monitoring' to work on Heroku?

[John McCaffrey]

I installed the new relic add on through the heroku site (not as a plugin or
via bundler), and its been working fine, but now I'd like to see the end
user monitoring feature they have, but it says I have to update the gem.

What is the best approach for this?

Technically I didn't setup the new_relic config file, heroku did that for
me. I realize I could uninstall the heroku add-on, install the gem via
bundler, and have it point to a new relic account outside of heroku, but
that seems odd to have to do that just to get the latest version of the gem.

Re: Gzip not available on Cedar?

[John McCaffrey]

Thanks for the play by play!

 I didn't get a chance to try out any of my apps on it yet, but I appreciate
the heads up on some of the things I might run into.

At first the lack of varnish seemed like a big loss, and that it would now
mean that your app server is requests that used to be served by varnish.

I read through this post on rack
cache,
which might not be the most up to date, but it eased my concern somewhat.

Getting the official word on the gzip thing would be nice.

thanks
-John

Thanks for posting the conclusion!

Posting the resolution only takes a few minutes, but its so helpful for

Most of my apps are back up...2 of them are having issues

[John McCaffrey]

I have a lot of single dyno free apps on heroku, and they are all reachable
except for 2.

http://simple-captcha-demo.heroku.com/  is a live demo of the different
captcha tools available in Rails.

   1. The app is running, (not getting the generic heroku  'Application
   Error') page, but is failing on db access
   2. tailing the logs shows the error is 'PGError: FATAL:  sorry, too many
   clients already'
   3. I can get into heroku console, but if I try to access the db I also
   get 'PGError: FATAL:  sorry, too many clients already'

I have another app that is a beta site for a client (so its pretty important
that it functions)

   1. I get generic 'Application Error' when hitting home page
   2. heroku logs --tail shows 'heroku[router]: Error H10 (App crashed) ->
   GET / dyno=none queue=0 wait=0ms service=0ms bytes=0
   3. attempting to increase the number of dynos did not help
   4. I can't get in to the console, I get the error

 Your application is too busy to open a console session.
 Console sessions require an open dyno to use for execution.

I'm not freaking out about this, and I haven't opened a ticket. I'm not
paying for this dyno yet, so I don't expect too much, and I realize the
Heroku team has been working like crazy to resolve this. (last year at
RailsConf they had a big outage, and had to explain it there at the
conference, and I bet its going to be a big topic this year as well.
Hopefully they'll be in a good position to give some pointers on how we
could architect our apps to be ready for this)

I just wanted to report that almost all of my free dynos are working, which
is great, and I'm sure these last 2 will come back soon.

As a side note, I learned that you can configure new relic to ping your app
at a specified interval, and notify you if the app is not up. Thanks New
Relic! (wish I would have had this installed 2 days ago!)

Re: Varnish and conditional GET

[John McCaffrey]

taking a look at that page using redbot.org

http://redbot.org/?uri=http%3A%2F%2Fhigh-night-436.heroku.com%2Fthingies%2F1

I
see that the cache is set to private, so varnish can't cache it and the max
age and age are both 0, so the browser thinks its stale, and has to
revalidate it.

For more info on this, check out the super-awesome 'Scaling
Rails'
series by Gregg Pollack and New Relic.

Leveraging client side caching, and varnish is the best strategy to get the
single free dyno to take you as far as possible. (heroku is great in that
they encourage your 'inner cheapskate' because you really can run a full
site on a single dyno pretty well if you tune things well)

Heroku demo: Captcha tools for rails

[John McCaffrey]

I've been doing a lot of security work lately, making sure a rails app meets
the security standards of a major financial institution.

In addition to input scrubbing, output escaping, and making sure exceptions
don't reveal too much data, I've had to implement basic captcha, to make it
harder for a bot to post forms.

Here's a post on 3 captcha plugins that I tested out and deployed to heroku

Re: Monitoring Server Load

[John McCaffrey]

Tom,

You can start with the new relic add on, and watch response times, and queue
depth.

What I've done in the past is run some load tests through a local deployment
to get a sense of how many requests the app can handle on a 'similar' stack
(postgres, thin, etc).

Then I run the same load tests against the app deployed on heroku, while
monitoring with new relic, to see if the times are close, and where the time
is being spent.

Based on that you get a rough idea of how many requests a single dyno can
handle for your app, and what you might need to do if you are expecting a
significant uptick in requests.

Before you look to purchase more dynos, see if you can leverage the browser
cache more effectively, and then look for what can be put in the varnish
cache.

You want to make sure that you aren't wasting your dyno by having it serve
up requests for static assets like css, js, images, etc. Then you want to
use page caching if you have places where that will work.

Good luck!
-John

Re: New Relic Bronze - how to install

[John McCaffrey]

try the ui.

If it seems like its not working for your app, create a vanilla rails app,
throw it up to heroku, add new relic to it from the UI, and see if that
works.  (attempting to rule out any conflict in gems from your other app.
Though I've never heard of any conflicts with new Relic before)

I've only added it using the UI interface though, so maybe there is a step

Re: App creation failing

[John McCaffrey]

basic questions that must be asked:

   1. Does the app work fine for you locally?
   2. Are there any gems that you think might not be registered or loading
   correctly?
   3. did you check the logs? (heroku restart)
   4. try restarting it? (heroku logs)
   5. remove parts of the app, or deploy another app with less stuff in it
   (to narrow down which thing its getting stuck on)

Maybe just an odd timing issue, give it another shot.

Re: How to get Ruby 1.9.2, Rails3, and PostgreSQL going?

[John McCaffrey]

Jay,

I'm in the process of going through the railstutorial.org chapters and
providing some coaching for some clients of mine that want to get up to
speed on rails. (and the railstutorial is a great way to do that!)

I would start with the most basic steps you can, and make sure that you use
rvm to keep your gems from conflicting.

(I assume you are talking about just getting the basic app he is describing
to work, not upgrading some other app you already had...with various
dependencies and issues not yet revealed to us)

It looks like you are not having a problem with heroku, but rather your
local setup. (so you might not get much response from this mailing list)

Here are the steps that I recommend

  rvm install 1.9.2  # if you hadn't already
  mkdir rails_tutorial
  cd rails_tutorial
  rvm use 1.9.2

#create a gemset that will hold all the gems for the rails_tutorial chapters

   rvm gemset create rails3tutorial

# write out a .rvmrc file that will ensure that whenever you are in this
directory, you use this gemset

   echo 'rvm use 1.9.2-p0@rails3tutorial' > .rvmrc

# cd out, and then back in again to have rvm ask you if you want to use this
gemset
cd ../
cd rails_tutorial
  # answer yes

# now we can install gems, and they will go into that gemset
  gem install bundler heroku
  gem install rails --version 3.0.3

# now let's build an app
  rails new first_app
  cd first_app
# start it up
  rails server
#just check that you have the index page
  open http://localhost:3000

# if we have something that works, lets create a local repo to keep track of
our changes
  git init
  git add .
  git commit -am 'initial commit'

# push it to heroku and see it live
  heroku create
  git push heroku master
 heroku open

#from there I'd do the scaffold step, check it locally and then push to
heroku and heroku rake db:migrate

Now I'm not on ubuntu, so maybe you are running into an issue I haven't
seen. At this point you may get better help from other people that are doing
the tutorial, and just follow what they do step by step.

Also, if you ever do 'sudo' gem install while using rvm you may cause issues
that can be hard to untangle. (gems not in the right place, wrong gems
loading, conflicts, etc)

good luck

Re: rake db:migrate appeared to start migrating from the very beginning on two different apps.

[John McCaffrey]

Are you the same guy that is having one app point to the DATABASE_URL of
another heroku app?

these wouldn't be the same apps, right? (cuz, well that would be the first
thing I would suspect)

Prior to running your migrations you can check the migration version with:
heroku rake db:version

Re: Running build on heroku using Integrity

[John McCaffrey]

So I gave it a try, and I don't see anything actually building (I added the
actual integrity project as a build target)

In the logs I see
Could not create directory '/home/slugs//.ssh'.
Failed to add the host to the list of known hosts
(/home/slugs/.ssh/known_hosts).
Permission denied (publickey).
fatal: The remote end hung up unexpectedly


I'm guessing this is because I copied the git:.. url which is gonna go out
over ssh
duh, that's not gonna work!

I then grabbed the https: version of the integrity repo, and tried that
I was able to build, but got an error that 'rr' was not found. I guess I'd
have to add any of the gems for any sub project into the main Gemfile, so
they are present when everything is executed.

I played around with a few variations and felt that:

   1. it would be nice to get some better feedback on the page, or in the
   logs. Most of the time I felt like it wasn't doing anything, but I would
   wait just to see.
   2. It would be nice to 'disable' a project so it wouldn't attempt to run.
   (I was testing public and private projects, and assuming that only one
   process would run on heroku, I wasn't sure if my other projects were even
   running, or if just the first one, which may have been misconfigured, was
   hanging the rest). If I could disable some projects then I'd know whats
   actually running. (Instead of having to delete them)


I then tried a private project of mine to see how that works.

On the http://integrityapp.com/ page, it shows how to set your github token,
so that you can access your private stuff. I tried this and it doesn't seem
to be fetching properly

I added the expanded logging addon
heroku addons:add logging:expanded

and was able to see more info when tailing the log
heroku logs --tail

at this point I still haven't gotten a private project to build, and it
doesn't seem like the integrity tests are running, even after adding 'rr' to
a Gemfile.

I tried to build the prawn project, and I at least got a 'success' message,
though I'm not sure it really built.
https://github.com/sandal/prawn.git

will play around with it more at a later time. I am interested in all of the
apps you can run on heroku, integrity, refinery, redmine, etc., and would be
interested in hearing any experiences people have had with it.

I just ran into an issue with this. I had an older version of the heroku

gem update heroku

now heroku logs --tail works

Re: Running build on heroku using Integrity

[John McCaffrey]

I tried getting integrity running on heroku a few weeks ago and ran into
various issues with gem dependencies, and bailed after various trial and
error attempts.


the error I got was
Bundler could not find compatible versions for gem "json":
 In Gemfile:
   broach depends on
 json (~> 1.4)

   json (1.1.9)

I don't think I was pulling from the same github project you were, so I'll
give this one a quick try and see what happens.

As this may be an issue with that project, and not heroku, you may find more
success in pining that author through github.

Re: postgres tuning

[John McCaffrey]

I've been working on postgres tuning for an app recently, and I was
wondering if you were able to change these configs locally and see a
meaningful improvement.

I've seen improvements of large queries with sorts, by increasing work_mem
(which can be done within your session), but other settings always seem to
take a good deal of fiddling with, in order to get them to make a
difference, so I'm wondering if you've already proven that this change will
help or not.

(it might be bold of me to assume that you'd pull down your prod data from
heroku, and fire up a local postgres to tune your queries against)

Here's a good list of postgres tuning options that you can do now
http://robots.thoughtbot.com/post/2638538135/postgresql-performance-considerations

I'd be interested in any of the things you've already done to improve your
performance on heroku, The more we share the better things are for all of
us.

Re: free vs. paid heroku app performance

[John McCaffrey]

If you think that its dying when the slug is being compiled, or you just
want to improve your slug loading time, you might want to tell it which
parts of your repo are not needed during runtime.

some common things to add to your .slugignore file
  *.psd
  *.pdf
  test
  spec
  doc

you might also check if any of your vendored gems/plugins are not needed
during runtime (testing related stuff most likely)

The point is not that having these components is slowing down runtime
(though they might, slightly), but rather that including them in the slug
will slow down the spin-up time for no good reason.

you can find out more at:
http://docs.heroku.com/slug-compiler

Re: Crazy slow AJAX performance

[John McCaffrey]

Sounds like an interesting problem.

To recap:
1. You do not see this behavior locally in Firefox or Safari, but only when
deployed to Heroku (and that's why you posted to this group)
2. Its always been this way, and nothing changed recently (new version of
jquery, etc)

Is this something that we can test ourselves on a public URL?

I could take a look at it using some of the low level tools that work in IE
(VRTA, fiddler, httpwatch, etc), as well as google speed tracer, which will
show you a breakdown of the events from dns lookup, request, download,
parse, render.

Is the payload large? Is it possible that it takes forever for it to be
parsed?

Not sure how easy it would be to take a completed response and then mock the
xhr call to see if taking the network out of the equation displays the same
problem (mocking the xhr states might be something that's already covered in
any of the javascript testing frameworks)

I've been evaluating a few of the browser tools, and would welcome a good
use case to test them against, and see which one helps identify the problem,
so go ahead and give us the url so we can try it out and give you a hand
with this.  (I know how frustrating a problem like this can be)

Re: Scaling limits and biggest app examples?

[John McCaffrey]

Its a good question, and one that you would want to ask of any platform you
plan to host on.

I just saw the heroku team at RailsConf, and they laid out some info that
was pretty interesting.

Here are my raw notes on their largest sites:

some of their bigger apps

   http://www.scvngr.com
explosive growth
featured on major sites
 millions of users

   http://www.syphir.com
   rules and smart push for gmail to your phone
anti-social, delay emails from facebook/twitter until the end of the
day, so I can get work done
they got huge spike in traffic
 spun up more dynos from the command line
brought them down ofter spike

   http://getcloudapp.com
   mac based, file sharing
shift cmd / enter takes screenshot
 pushes to cloudapp, heroku -> s3, short url, copies to clipboard
>4k req/min
 20% week over week growth
dedicated db

When you start to think about the performance of your application, there are
a few points I woud want to make:

   1. Scalability does not equal performance. While they are related, its
   possible to have a scalable app that is actually pretty slow (facebook
   doesn't feel all that fast to me, but it scales to handle its users). Heroku
   gives you a scalable platform, you tune your app to be as performant as
   possible, and spin up more dynos as needed. This lets you handle growth over
   time, or in bursts, in a balanced progressive way.
   2. What kind of performance issues do you expect? Heavy writes, mostly
   reads, lots of background processing, CPU intense activities, consistent
   usage or month-end spikes? Facebook and google are very different apps, with
   very different architectures, once an app gets to that size, I think the
   hosting solution becomes very custom.
   3. Heroku speeds up the development and deployment process, making it
   easier to get an app out and get critical feedback before the 'cement'
   dries. Its more important to launch a functional, but slow, application than
   to delay the launch or prematurely tune an app in the name of performance.
   (tune it once your users tell you which features they actually care about)

There is an overhead that is added by the heroku system, and it would be
interesting to see what impact it has. It might be as simple as having an
app deployed on two hosts, run some performance tests and see what the
differences are.

Has anyone done anything like this yet?

Re: sass_on_heroku / hassle

[John McCaffrey]

I threw a quick app together to show how haml and sass can work on heroku,
along with formtastic and a nice jquery dynamic styles changer here:
http://mccaffrey-formtastic.heroku.com/

The project is on github here
http://github.com/jmccaffrey/formtastic_sass_on_heroku

Let me know if you have any questions, I did this a few months ago...

I hadn't heard of hassle, I'll have to check it out.

Re: App Monitoring

[John McCaffrey]

Also, the new relic add-on will give you alerts for failures and changes in
response times.

While this isn't the same as url monitoring, it does provide some very
critical diagnostic info, including your heroku queue depth (which is very
cool), and its free!

I wonder if anyone has had success with any of the free url monitoring sites
out there?
I found this one
(intervista)which
will ping your site every 60mins from different locations, for free.
(though it looks like they want you to put an image banner on the page you
want them to monitor, which could just be some other unimportant page you
have)

I was also wondering if anyone has used a url monitoring site like this to
trigger a 'cron-like' server process? (Have the site monitor hit a specific
url that will trigger some task or process that you need.)

It seems a little convoluted, but depending on the nature of the task, it
might not be that bad. (update an rss feed, publish some results, do some
cleanup of old session data or something)

Re: Sass_on_heroku compiled css shows line number

[John McCaffrey]

so I went back to my project and tried to push it out to heroku again

Here's what I did, (not sure which step made it work exactly)
1. made sure my .gems file had these
haml --version '>= 2.2.0'
chriseppstein-compass --version '>= 0.8.7' --source gems.github.com
2. removed .gitignore entries for tmp/ and public/stylesheets/compiled
3. made sure all stylesheets were compiled and in the right dir
4. added this to config/initializers/compass.rb
Sass::Plugin.options[:never_update] = true

So  I figured this should take care of it all, and I should be ready to
rock. I  mean I did everything I found on every blog, right?

Wrong, still not working.  Why?  Cuz I'm an idiot, that's why.
At some point I must have decided to get all fancy and tell rails to cache
multiple css files together, and i added this (in haml syntax)
   = stylesheet_link_tag 'formtastic', 'formtastic_changes.css' ,  :cache =>
'formtastic_base'

well heroku doesn't like that, so I took off the cache part (plus I'm not
sure that it really makes sense to combine those two files as they are
intended to be loaded separately, and in a particular order)

now I have a version of my app deployed and working. Under this current
plan, I'd have to make sure that I am pushing all of the compiled css files,
which I'm not keen on, but we'll try it out and see.

but it was worth the 20 mins to give it another try

Re: Missing table error with db:push

[John McCaffrey]

I don't have a specific answer for you, but in general I would suggest using
postgres locally, to make it easier to debug issues like this.

That way you can rule out 'postgres'  issues vs 'heroku postgres'. You'll
see in other threads some various tips when migrating from mysql to
postgresql, and you'll find it a lot easier to go through that stuff and
being able to verify it locally.

Re: Postgres tools?

[John McCaffrey]

The standard setup described on postgresql.org should work for linux or
windows  (mac is a
different story)

I'm currently in the process of trying to keep a rails app working with
mysql and postgres, in an effort to stay db agnostic, 'heroku ready', and
because I like postgres more for lots of other reasons..

If you are converting an existing app, here are some things I've run into::

   1. Case sensitivity (mysql is case insensitive, postgres is not)
   2. convert to sql standard functions: use coalesce instead of IFNULL,
   case instead of if
   3. Mysql lets you do 'limit 10,10' in postgres you have to do 'limit 10
   offset 10'
   4. string escape syntax is different

there are similar client/gui tools for postgres. (though, I've recently gone
back to using Netbeans built in query tool, as it saves all my recent
queries and just makes life easier)

Google for: rails ~move mysql to postgres   to see what others have said
about general differences (also, keep searching through this heroku list, as
many people have gone through this)

One of the better write ups comes from the guys over at the very awesome
real estate site www.redfin.com
 http://blog.redfin.com/devblog/2008/02/mysql_to_postgres.html

Best of luck,
and welcome to Heroku!

Re: Sass_on_heroku compiled css shows line number

[John McCaffrey]

I tried to deploy an app with compass, and wasn't able to get it to work. I
didn't dig into it enough, (well I tried a lot of stuff, but wasn't able to
get it to work), so I took a step back to make sure I could get the basic
sass stuff to work.

Once you get your issue taken care of, I'd like to know what steps you took
to get compass to work, as it seems your issues are more related to compass
than sass on heroku.

The css files for my http://mccaffrey-formtastic.heroku.com/  site do not
have line numbers, even in development.

My other project for work, which is using compass, does have line numbers in
development, but not in production.

Re: Sass_on_heroku compiled css shows line number

[John McCaffrey]

I don't know if you are referring to a different plugin, but I'm using the
one mentioned on the heroku blog
http://blog.heroku.com/archives/2009/8/18/heroku_sass/

I put together a
quick demo to show how awesome sass, haml, and formtastic are, so some
people on my team could start 'drinking the koolaid' with me!

http://mccaffrey-formtastic.heroku.com/

my application.sass includes these

@import scaffold.sass
@import formtastic_base.sass
@import skintastic.sass

but the final compiled css doesn't have any line numbers or unexpected
artifacts

Re: HTTP Caching / Rails / etag / last modifed / varnish

[John McCaffrey]

Thanks for pointing out redbot.org, its very handy. I used it against my own
heroku site prawn.heroku.com  (examples of how to generate pdfs in rails
with the Prawn, prawn-to libraries), and I noticed that the server times
would vary as I refreshed the page.

http://redbot.org/?uri=http://prawn.heroku.com

the first time I hit it, the server time was considered to be correct, but
subsequent refreshes returned anywhere from 5mins ahead to 6hrs ahead. I
assume this is just at the nginx server, and doesn't mean that the server
time on my rails server is out of sync.

Am I reading this right?

thanks,
-John

Re: herokugarden is down again

[John McCaffrey]

ok, you've convinced me that its worth moving over. (I hope you're not like
my older brother telling me 'the water's fine', only to find out that its
freezing, or 'this pepper isn't hot at all')
I was really excited about herokugarden, but when I was trying to convince
some other people on the team about how awesome it was, the site wouldn't
load.

So did someone say the online editor isn't available on heroku? what about
being able to get to the rails console? (I guess I'll need to set aside some
time and dive in)

Re: Spam

[John McCaffrey]

I triple vote for that. I want to keep up to date on heroku, but the spam
really sucks.
