In the 0.x you can add extra dependencies by adding a ‘deps’ key to your 
zotonic config file.

http://docs.zotonic.com/en/0.x/ref/configuration/zotonic-configuration.html?highlight=deps#deps
 


Master is different, there we are using real OTP apps for all modules.

Ah, in that way.

I believe QuickCheck is a commercial product.
But there is a “mini” version that you can download from Quviq

Re: [Zotonic-Dev] How to correctly set the cookie when the ztonic starts?

['Marc Worrell' via Zotonic developers]

The session cookie?

There is a config for that.

You can change the name by adding a configuration “site.session_cookie_name”.
It defaults to “z_sid”.

Re: [Zotonic-Dev] zotonic CI deployment best practice for 2019

['Marc Worrell' via Zotonic developers]

Hi Eddie and Lloyd,

“It depends” is indeed the correct answer...

Most Zotonic installations fall in two categories:

1. Deployment via a Docker container, which is updated before deployment
2. Deployment via git (manual or automatic)

Some follow (1),  I follow (2).

Nice thing of (2) is that it allows for hot code upgrades and quick turnaround 
of small patches.
When we are i a development cycle for new features we might have 10 to 20 
deployments per day.
This goes very smooth, we even deploy minor updates to Zotonic and dependencies 
using hot code upgrades.

Zotonic itself can watch changes in the file system and dynamically load new 
files.

Most of the updates we deploy have only minor changes.
Think of changes to templates, css, or translations.
And minor Erlang changes (ie. not completely new apps or other dependencies).
That is why we can have updates-via-git without service interruption.

The orgs that deploy via Docker (option 1) - have typically less frequent 
updates and perform periodic major updates.
As the whole container is updated this also restarts the Zotonic server.

Of course it is also possible to deploy using the OTP release mechanism.
This is something that will be possible with the 1.0 (really soon now) of 
Zotonic, as that version is OTP compliant.
I personally never had the need to use OTP releases as the version control via 
git is good enough for us.
(Especially with rebar3 managing versions of dependencies.)


Cheers, Marc

Re: [Zotonic-Dev] zotonic CI deployment best practice for 2019

['Marc Worrell' via Zotonic developers]

Hi Lloyd (and rest of list),

For Zotonic I have seen two setups:

1. Only Zotonic (Erlang)  (single machine)

With this setup external port 80 is redirected (using iptables prerouting 
rules) to 127.0.0.1:8000.
And port 443 to 8433. Erlang is directly handling all (SSL) traffic.
Same is done with the SMTP port 25, which is usually mapped to 2525.

2. Using a proxy (one or more machines)

In this haproxy or nginx are used to terminate the SSL connections and proxy 
requests to Zotonic/Erlang.
The Zotonic node is either running locally or on some other host in local 
network.
In this setup it is also common to have a mail server running to forward 
incoming email to the Zotonic/Erlang node.


Setup 1 (direct) is the easiest for small single-server operations.
Setup 2 (proxy) is when you want to have multiple machines and a local network.


We have setup 1 running on a €50/month VPS, handling monthly traffic of 1.5+ TB 
(~2M monthly visitors).
Another company is running setup 1 on dedicated hardware with more than 1M 
hourly requests.
(That server is mostly idle…)

So for most (98%?) sites the simple setup is actually very realistic.
You just need to be sure that you have a good backup scheme, as it is a single 
machine.
I know of some people that are working on a “lukewarm” failover setup.

With the single VPS server solution we didn’t have any significant down time in 
the last years and
usually have 100% monthly uptime (according to pingdom).

So, for me, the single server solution works best.
Especially with a VPS where the hosting company moves the VPS in case of any 
hardware problems.

Cheers,

Marc

Re: [Zotonic-Dev] zotonic CI deployment best practice for 2019

['Marc Worrell' via Zotonic developers]

Hi Eddie,

Hope David (or someone else) can chime in on the docker question, as that is 
quite unknown territory for me.

For the 1.0, we are currently working on getting the sessions re-worked.
This would make the admin working again, and gets us a lot closer to merging 
cotonic into zotonic.

Then we would need to:

 - Merge in some changes from 0.x
 - Fix uploads of files
 - Tests
 - Update the docs (so people don’t get too confused)

At this point we are postponing major UI changes.
Only the logon/logout forms will see quite some changes, as they interact with 
the new transports and session management.

After the first release we will add deeper integration of the new UI (Cotonic) 
code and security system.

I still hope to get quite far by February.
However, got some high priority projects during this period which might push it 
to March.

Cheers, Marc

Re: [Zotonic-Dev] What kind of mistake I do not understand?

['Marc Worrell' via Zotonic developers]

I think this is a fresh compile and this is the master, which is now OTP.

The compile option will be removed and is currently only working for 
incremental compiles.

You can use ‘make’ to compile (which calls rebar etc)

Erlang crashes?

Which OTP version are you using?
And is it a clean build (maybe it doesn’t like a beam file from another OTP 
version).

Seems like something is going wrong with Hex and fetching bcrypt.

What you could try is to delete the ‘./rebar3’ application and let the Makefile 
fetch a new version.

Re: [Zotonic-Dev] Re: What kind of mistake I do not understand?

['Marc Worrell' via Zotonic developers]

This is the tip of the master?

I just tried a clean build on my machine (macOS 10.13, Erlang OTP-19 via kerl) 
and everything compiled.
Also the Travis-CI builds work.

So I am wondering what the difference could be with your setup.

You are also in the “zotonic” directory when running ‘make’?

In which file was it?

Then I can check the master.

Still strange that it does compile on Travis-CI.
Which Erlang version are you using?

Re: [Zotonic-Dev] Will zotonic run in alpine linux?

Hi Ed,

Is there something special with Alpine?

In principle Zotonic runs on any Unix-alike that supports:

 - Erlang
 - PostgreSQL
 - ImageMagick

I guess Alpine supports those?

['Marc Worrell' via Zotonic developers]

OTP-20 should be ok.

As this  is master, could you try:

rm -rf _build
rm ./rebar3
make

This forces a complete rebuild and a fresh install or rebar3.

I once had a problem with a version of rebar3, that was resolved by removing it.
The Makefile will fetch the newest rebar3 release.

I see "smp:1:1” in the system version.

Hi,

This gives you 4 schedulers.

Check where ‘erl’ is started in the following files:

If you start with ‘debug’ (like with ./start.sh):

src/scripts/zotonic-debug

If you start in the background (./bin/zotonic start):

src/scripts/zotonic-start

Re: [Zotonic-Dev] Zotonic fails to startup after make and bin/zotonic debug

['Marc Worrell' via Zotonic developers]

Hi Eddie,

This error about the ‘port program’ is caused by running then beam.smp (erlang) 
as root user.

There is an explanation here:

https://github.com/aeternity/aeternity/wiki/Troubleshooting#node-wont-start-with-privileged-user
 


In short: try to run zotonic as a “normal” user, and not as root.

Re: [Zotonic-Dev] Make fails after installing zotonic on ubuntu 16.04.5

['Marc Worrell' via Zotonic developers]

Hi,

I think cowboy is now OTP-19+ only.

Can you check with OTP-19 or 20?

Cheers, Marc

Re: [Zotonic-Dev] Make fails after installing zotonic on ubuntu 16.04.5

['Marc Worrell' via Zotonic developers]

We are using Ubuntu and Debian servers.
And for dev Mac OS X.

For switching Erlang releases we are using kerl.
That works fine, in fact I use it now even in production.

My own servers are running at TransIP.
But others are running servers at many other places.

I might try to get a demo server up & running with Scaleway.
They are pretty cheap, but no idea if there is a catch to that price.

Did you try with stock Ubuntu or Debian?

Maybe others have some suggestions?

Cheers, 

Marc

Hi Eddie,

I pushed an update to our letsencrypt version.

It now works on our cotonic branch, and I merged that change into the master.

Can you check again?
(Don’t forget to enable ‘cron’)

Please check the log files if anything goes wrong.

Did you just try git pull and then make?
That should update the dependencies.

Re: [Zotonic-Dev] Any sample example for REST API example

['Marc Worrell' via Zotonic developers]

Hi Kulveer,

The master (1.0-dev) has a new implementation for the API methods.

Previously you would make a service module.
This has been replaced with direct access to the models.

The API calls get mapped on m_get. m_post, and m_delete.

The url for a model is:

https://example.com/api/model/yourmodel/get/some/path 


This calls your model in the same way as:

{{ m.yourmodel.some.path }}

In a template.

For a delete (calls m_yourmodel:m_delete/3):

https://example.com/api/model/yourmodel/delete/some/path 


And post (calls m_yourmodel:m_post/3):

https://example.com/api/model/yourmodel/post/some/path 


The payload on a post can be anything that the model accepts.
It will be packed in a MQTT message that is delivered to the model.

The models will send their result back in the HTTP response (as JSON).
If you don’t expect an answer then you can tag an empty response topic to your
request:

https://example.com/api/model/yourmodel/post/some/path?response_topic= 


Or, alternatively, you can route the response to some other topic:

https://example.com/api/model/yourmodel/post/some/path?response_topic= 
some/topic/foo/bar

We will document this in the master documentation which is being adapted to the 
new
capabilities.

Note that the 0.x uses the special service modules (as documented in the 0.x 
documentation).

We have changed this behavior so that the API methods (models) are accessed in 
the same way via:

 * HTTP
 * MQTT
 * templates

And also give access to the MQTT topics via a normal HTTP POST with payload.

Hope this explains a bit.

Cheers, Marc

Hi,

Looks like the ipv6 listener can’t start.

We check if ipv6 is available and if it is we start the listener.
This is in zotonic_sup.erl:

Apparently the system pretend there is ip6 but doesn’t really support it.

You can disable starting the ipv6 listener by providing a specific listener 
port instead of ‘any’ in the zotonic.config

Replace this

> %%% IP address on which Zotonic will listen for HTTP requests.
> %%% Always overridden by the ZOTONIC_IP environment variable.
> %%% Use 'any' for all IP addresses.

With this:

> %%% IP address on which Zotonic will listen for HTTP requests.
> %%% Always overridden by the ZOTONIC_IP environment variable.
> %%% Use 'any' for all IP addresses.
>{listen_ip, {0,0,0,0}},

If this fixes the problem then we can look into a better ipv6 detection method.
One of the methods I am thinking of is by actually opening the port before 
proceeding.

Cheers, Marc

Re: [Zotonic-Dev] installing zotonic on Freebsd jail

['Marc Worrell' via Zotonic developers]

Hi,

Do you also see some messages on the Erlang command line?

Did you try to connect with http to :8000 and see if there is a redirect to 
https :8443?
If so then Zotonic is listening and responding.

If there are errors on the erlang command line and you are on OTP21, then you 
might need to get a patched OTP install.
I just saw someone referring to TLS handshake errors on OTP 21.3.
That problem was fixed in 21.3.8.5

Cheers, Marc

Interesting, how & where do we crash on IPv6 addresses?

Maybe there is a difference between Linux and BSD here.

Re: [Zotonic-Dev] Zotonic 0.57.0 - ssl Inssuficient Security - no_suitable_cipher error

['Marc Worrell' via Zotonic developers]

Hi Alvaro,

That is strange.

I also did a clean build on OTP-22 without problems.
And our Travis-CI build on 22 also works.

I am also using OTP 22.3
(Quite recent build)

Which version of erlware_commons do you end up with?

I am at a8b46e077034938fd82f57876103270311e6835b

Maybe your rebar needs updating?

I have:

> zotonic-0.x marc$ ./rebar --version
> rebar 2.6.4 17 20160831_145136 git 2.6.4-dirty

Cheers,

Marc

Re: [Zotonic-Dev] Zotonic 0.57.0 - ssl Inssuficient Security - no_suitable_cipher error

['Marc Worrell' via Zotonic developers]

Great!

Will release the 0.57.1 today, was waiting on your test result.

We have a rule that we follow the last 3 OTP releases.

That is, there is some work to do for OTP-23, especially in some dependencies.

For the 0.x we are supporting 19+ due to production servers.
For the 1.x series (aka master) we are supporting 20+, and might change that to 
21+.

At the moment I am not too concerned about the deprecation warnings.
We can fix those in due time.

Happy that you got everything up & running,

Cheers, Marc

Re: [Zotonic-Dev] Lost access to website admin panel

['Marc Worrell' via Zotonic developers]

Hi Rishit,

Sorry for that email - something went wrong there.

You can find the passwords for the admin users in two different files.

Is it a 0.x version?  For now I assume it is.

The admin password for the zotonic status site can be found in:

~/.zotonic/0/zotonic.config

The admin password for the site can be found in:

zotonic/user/sites//config

Where “zotonic” is the directory of zotonic.

Hope this helps.

Cheers, Marc

That is easy, especially if your data is a resource (aka page).
In that case you can use the generic resource and query routines.

If your data is a special table then you can directly access your models from 
the templates.

> - Render links to RUD actions for each record

We use mostly async messages for this kind of actions.
The messages are posted over the MQTT message bus to the server (and back to 
the client).

You can use “wired” events for which we have all kinds of actions.

Or you can use (or bind) topics to post messages to the server (models).

> - Render forms to CRU the Resource Category

We don’t have routines to automatically generate forms.

Our philosophy is that everything is a thing.

That is until it isn’t.  For example with payments, which need specific 
administration and access.
For those we add extra pages and menu items in the admin.

No it is a generic content management framework, geared towards semantic data.

See some examples here:

You are welcome :-)

Any example templates we provide are very simple, so they don’t provide signup

Maybe we should just remove (or discourage to use) those docker images - we

We have a init file that can be used for Hetzner instances.

https://github.com/zotonic/zotonic/blob/master/cloud-init/zotonic-cloudinit.yml


We have still to update it for Ubuntu 22 - currently you can do an upgrade 
after installation.

What we often do is:

- The above script
- Checkout the website repo on the correct branch into ~zotonic/
- Symlink from ~zotonic/zotonic/apps_user/  to the website repo
- We also make sure that there is a local priv/zotonic_site.config or that in 
priv/config.d/ there is a config with the local information.
- Just run Zotonic from ~zotonic/zotonic with "bin/zotonic start"

You can also add this start command to the startup scripts of the server, so 
that after reboot the site will start.

As the site is now checked out from git, a deploy is just a click on the update 
button in /admin/status

We periodically just update zotonic from upstream, also with git pull.
Normally this can be done as a hot code upgrade, otherwise a quick stop, pull, 
make, start will do the trick.

The above is the lazy and low-tech approach.
At Driebit they work with Docker images.
And on our wish list for this year is to start making real releases (looking 
into some rebar3 issue for that…)

If you enable and configure mod_filestore and mod_backup, then you can have 
extra backups of all your data on a storage box.
(Besides the backups that Hetzner is doing for you.)

If the rebar3 issue is resolved then we can release Zotonic 1.0 and will update 
all Hex packages.

Cheers!

Marc

Re: [Zotonic-Dev] Dmain Name Change

['Marc Worrell' via Zotonic developers]

Hi,

You can just change the hostname in your config.
We mostly add the old hostnames to the hostalias, so that previous domain names 
still redirect to the new one.

No need to change databases.

Don’t forget to request a new SSL certificate.

Cheers, Marc

Re: [Zotonic-Dev] Content Blocks

['Marc Worrell' via Zotonic developers]

Hi Seann,

I would expect it to be:

> {% for blk in id.blocks %}
> {% include "blocks/_block_view_text.tpl" %}
> {% endfor %}


But that renders only blocks of the type ’text’.

The suffix _text is the type of the block, we added different templates for the 
different types.
You can see in the mod_survey how we use those to render the different 
questions.

That is also why we add the type of the block when including using the 
“_blocks.tpl”:

> {% for blk in m.rsc[id].blocks %}
> {% optional include ["blocks/_block_view_",blk.type,".tpl"]|join blk=blk 
> id=id %}
> {% endfor %}

(id.blocks is shorthand for m.rsc[id].blocks)

Cheers, Marc

Re: [Zotonic-Dev] To Proxy or not to Proxy...

['Marc Worrell' via Zotonic developers]

Hi Seann,

We are generally running Zotonic directly on port 80/443 or just with firewall 
redirect rules.
In our cloud-init file we are now using the direct approach, as Maas-Maarten 
found that there is a problem with the firewall-redirecting taking up too many 
resources and not being able to handle the amount of connections they need.

Having a proxy indeed kind of doubles the request overhead.
We confirmed that in tests for ping-like requests and files.

There are a couple of reasons people do use a proxy:

- Being able to (with standard tools) block requesting IPs
- Manage certificates in a central way (if you have a sysop person)
- Separate responsibilities between sysop and devop.
- Extra logging via the proxy

There are a couple of reasons people do NOT use a proxy:

- Simple setup - less moving parts
- Let Zotonic handle all certificates
- Performance (useful for smaller servers)

Zotonic can log as well, we just don’t do it per default as the millions of log 
lines do not help.

We have been thinking about a simple access-log-counting thing.
Just didn’t have a customer yet that wanted it, and wanted to pay for it :-)

The email is almost always sent by Zotonic directly.

Unless there is a sysop responsible for all email, then sometimes the email is 
sent via a relay.
We also sent email via (for example) mailgun, which gives us better control of 
inbox placement with especially hotmail/outlook and still good email-address 
status via mod_mailgun.

We also receive email, sometimes via a relay on a central server (that also 
manages the corporate email addresses).
Most often just by directly listening on port 25.

Cheers,

Marc

Re: [Zotonic-Dev] mod_payment(_stripe)

['Marc Worrell' via Zotonic developers]

Hi!

Indeed paysub is in active development at the moment.
And it is geared for paid subscriptions.

The mod_payment (and friends) is more for one-off payments and simple recurring 
payments.
I think Driebit is using it - at least the 0.x version of the module(s).
As they are moving sites over to the 1.x they will definitely start using the 
new versions soon (if they don’t already).

Cheers, Marc

Re: [Zotonic-Dev] mod_payment(_stripe)

['Marc Worrell' via Zotonic developers]

Hi,

Actually, that sounds like a kind of “eternal” membership :-)
Maybe Stripe has a type of one-time-payment subscriptions?

The paysub module can dynamically assign a user group depending on the 
subscriptions.
The user group could then allow access to the content groups of your paid 
content.

Cheers, Marc

Re: [Zotonic-Dev] SSL

['Marc Worrell' via Zotonic developers]

We are using the library:

https://github.com/zotonic/zotonic_ssl

For the SSL certificate inspection.
Could you file an issue there?

If you want to use Let’s Encrypt with Zotonic 1.x (master), then you can also 
just enable mod_ssl_letsencrypt.
It will handle requesting certificates and also extending them before they 
expire.

Cheers,

Marc
