Re: [Question] API Regions Report

[Daniel Klco]

FYI I took a crack at adding a webconsole status screen for this:
https://github.com/apache/sling-org-apache-sling-feature-apiregions/pull/16/files.
You can see the format in one of the test artifacts:
https://github.com/apache/sling-org-apache-sling-feature-apiregions/blob/268b43b50f66518a236f345607bdc40c530a780b/src/test/resources/printer/populated.txt

More than happy to take suggestions or improvements, but it seems like it
tells you what you'd want to know as a developer.

Re: [Question] API Regions Report

There's a reason for that. :-) I revised the script following your email.

Rev 1 used reflection to construct a new RegionConfiguration using the
BundleContext.

[Question] API Regions Report

[Daniel Klco]

All,

Is there a way to see a report on the API regions for an instance as a
consumer / extender of Sling?

It seems like all of the information you'd need is in the API Regions
Runtime RegionConfiguration[1] class, but that's not in an exposed package.

The case I'm thinking of is if you are a customizer of a Sling-based app
and are importing a package that was not exposed in the API region of your
bundle, how would you diagnose why the package is not resolving even though
it is exported? If you don't have direct access to the model used to create
that app (or if you aren't familiar with reading model files), I can't see
how you could diagnose the issue.

I wrote up a groovy script to dump this configuration, but, it's more than
a little hack-y:
https://gist.github.com/klcodanr/28385db0ce6df72be36a4f60b433a8ec

If there's not a good way currently, would others see value in having a
status web console to dump this information?

Re: Apache Sling Commons Messaging Mail

[Daniel Klco]

Hey Nicola,

The Apache Sling Commons Messaging Mail bundle uses Commons Crypto to
encrypt the password for the SMTP server. You'll need to provide the
configuration for Commons Crypto including:

   -
   
org.apache.sling.commons.crypto.jasypt.internal.JasyptRandomIvGeneratorRegistrar
   -
   
org.apache.sling.commons.crypto.jasypt.internal.JasyptRandomSaltGeneratorRegistrar
   -
   
org.apache.sling.commons.crypto.jasypt.internal.JasyptStandardPBEStringCryptoService
   - org.apache.sling.commons.crypto.internal.FilePasswordProvider

You can see the configuration (sans secrets) I use on my personal website
here:
https://github.com/klcodanr/danklco.com-site-cna/blob/cloud-native-sling/feature/src/main/features/site.json

Once that's set up correctly you should see an option under the 'Available
crypto service' here:
[serverhost:port]/system/console/sling-commons-crypto-encrypt

>From there you can enter your password to encrypt it and use it in
the org.apache.sling.commons.messaging.mail.internal.SimpleMailService
configuration.

Hope that helps!

Re: Session state management

[Daniel Klco]

I wouldn't _think_ so since the IDP should support re-authenticating
the user if they switch servers. I'd look to Cris Rockwell to comment
on this however as he's been driving this implementation.

Sling supports a pluggable authentication system[1] and includes
support for form based[2] authentication. You can invoke the
form-based authentication endpoints directly to login / out via JS.

> 2) extend (logged) user data with custom info (state management)

In Sling, each user has a Resource representation under /home/users.
You could create additional child resources underneath the user's home
resource to create profile data.

> 3) restore the session state in subsequent WS calls (without login
> again...)

In form-based authentication, Sling uses cookies to keep the Session
ID / Sling authentication between requests so this should be
transparent. This works well for "sticky" load balancing, but will be
challenging if you cannot ensure the user lands on the same server
between requests.

I would also note, it's best practice to not have Sling be the system
of record for user data. Another SSO / user data system will ensure
consistency across multiple Sling instances. There's a LDAP support
bundle[3] from Jackrabbit Oak (the underlying repository
implementation) which can be installed into recent versions of Sling.
We also have a work in progress implementation of SAML support in the
whiteboard (sandbox project).

Re: Localized Content

[Daniel Klco]

Thanks for clarifying the use case. Sling CMS uses the Sling i18n library
as Robert provided.

The Sling GET servlet which is serving the JSON response is simply reading
the resource value, it will not invoke i18n.

To get your message localized, you would need to either write a script and
use the fmt:[1] tags in JSP or @i18n attribute[2] in HTL or write a servlet
/ Sling Model with the Exporter framework[3] and then use the i18n provider
to retrieve the localized content as shown in the
HTMLValdiatorInsightProvider[4]

Depending on your use case, you may also be interested in Sling Resource
SuperImposing[5] which mirrors a resource structure but allows you to
"superimpose" properties (such as translated values) in that structure. I
have gotten it to work in Sling CMS, but haven't figured out (due to time
constraints) how to get the Sling POST servlet to post to the
*Absolute* resource
rather than the *SuperImposed *one.

Hope that helps!

Dan

Re: Resource to json serializing

[Daniel Klco]

Sounds like a use case for Sling Models Exporter:

https://sling.apache.org/documentation/bundles/models.html#exporter-framework-since-130-1

https://blogs.perficient.com/2018/07/26/no-servlets-required-exporting-data-with-sling-models/

The only caveat is that it's designed for named parameters, if you really
need it to be completely configurable at runtime, I'd suggest creating a
servlet attached to a resource type that filters the current resources
value map and uses Jackson to convert it to a JSON.

Interesting, what version of Composum? I'm seeing the following in Composum
1.12.0:

Re: Nodetype management

[Daniel Klco]

Juerg,

Try changing the filter (the second icon to the right on below the tree) to
"unfiltered". The jcr:system node should appear.

Re: Nodetype management

[Daniel Klco]

Juerg,

In Sling 11, there's a status console in the OSGi Console which shows the
JCR namespaces:
http://localhost:8080/system/console/status-JCR%20Namespaces

And you can see the node types via the Composum Node Browser:
http://localhost:8080/bin/browser.html/_jcr_system/jcr%3AnodeTypes

Re: Sling Slack Channel

[Daniel Klco]

Chris,

I agree, I'd be 100% on board with a Slack channel for Sling. A couple
thoughts:

 - There is already a slack org for the ASF: the-asf.slack.com we could use
rather than setting up another slack org
 - We probably should call a formal vote rather than asking for replies in
this thread

Dan

Repoinit Classpath

[Daniel Klco]

I'm looking into executing a Repoinit script from the classpath of a bundle
upon installation using the references property, but can't work out the
correct format.

According to the docs:
https://sling.apache.org/documentation/bundles/repository-initialization.html

It looks like I should be able to specify any URL, but I'm not seeing how
it would be possible to get a reference to a resource in a bundle.

I tried a couple variants, such as:

references=["jar:[pid]-[version].jar!/provisioning/model.txt"]
references=["jar:inputstream:[pid]-[version].jar!/provisioning/model.txt"]
references=["classpath:/provisioning/model.txt"]

I could think of how to reference it by a file:// URL, but that wouldn't be
stable between different instances.

Re: OIDC or SAML2 for Sling

[Daniel Klco]

Hey Chris,

This looks like a really good start! A couple of thoughts:

   - It looks like a lot of exceptions are re-thrown as Runtime exceptions
   which IMO tends to obscure expected exception handling, it looks like this
   is WIP, but wanted to call it out
   - You may want to look at the Dynamic Class Loader Manager:
   
https://sling.apache.org/apidocs/sling8/org/apache/sling/commons/classloader/DynamicClassLoaderManager.html
   - One thing to think about is how to store group membership. Due to a
   certain project that some of the Jackrabbit folks are aware of, I've found
   out quite painfully that the default Jackrabbit group membership has a hard
   limit to the number of user -> group associations before performance gets
   geometrically worse. You'll want to make sure your implementation supports
   dynamic group membership if your user count is going to get into the
   hundreds of thousands:
   
https://jackrabbit.apache.org/oak/docs/security/authentication/external/dynamic.html

Hope this helps and thanks for taking this on!

Re: org.apache.sling.api.resource.Resource from Image File

John, to clarify, the provided link was just an example of how one might
import files into a mock Sling repository for Unit testing with Sling
Mocks. I would not expect you to import it as a dependency in your project.

Re: org.apache.sling.api.resource.Resource from Image File

[Daniel Klco]

Assuming you are using Sling Mocks, you can load the file in as a resource
into the Sling Context, see:
https://github.com/apache/sling-org-apache-sling-app-cms/blob/master/transformer/src/test/java/org/apache/sling/cms/transformer/helpers/SlingCMSContextHelper.java

Re: Content Security Policy Headers

[Daniel Klco]

Jason,

Rather than putting the headers in Sling, I'd recommend supplying the CSP
in your caching (httpd etc) layer. Something like this:

Header set X-Frame-Options "ALLOW-FROM https://launch.adobe.com;

   Header set X-XSS-Protection "1; mode=block"

   Header set X-Content-Type-Options "nosniff"

   Header set Feature-Policy "sync-xhr 'self' https://www.danklco.com;

   Header set Content-Security-Policy "default-src https: data:
'unsafe-inline'"


I use this on my personal site and have an A rating:
https://securityheaders.com/?q=https%3A%2F%2Fwww.danklco.com%2F

Dan

Re: Hosting Sling

[Daniel Klco]

I have a bit, honestly I'd just run it in the cloud.

I'm using a reserved t3a.micro instance for my personal website. I would
say you need at least 1 vCPU and 1GB of memory to keep it up and stable any
less than that and you have to do swapping and that's bad. With a
1-year reservation it's only ~$50 / year.

I'd recommend taking a look at the Vagrant setup for Sling CMS as there's
some good stuff in there around configuring Apache httpd to act as a proxy
and caching layer. I'd also just recommend taking a look at Sling CMS as
it's a pretty nice quickstart to getting a working website in Sling.

Re: A maven archetype for apache sling cms

[Daniel Klco]

I have created a first run at a Sling CMS project archetype:
https://github.com/apache/sling-org-apache-sling-app-cms/tree/master/archetype

You should be able to build it with:
mvn clean install

And then use it with:
mvn archetype:generate -DarchetypeGroupId=org.apache.sling
-DarchetypeArtifactId=org.apache.sling.cms.archetype
-DarchetypeVersion=0.12.1-SNAPSHOT

Ruben Reusser has brought up a good point, however, there's an effort to
consolidate the number of archetypes for the Apache Sling project. Before I
release this, I'm going to check with the rest of the team if this is
sufficiently different or should be incorporated into the consolidated
archetype.

Re: A maven archetype for apache sling cms

[Daniel Klco]

Thanks Chris for bringing this back up. I'd meant to implement such an
archetype earlier and unfortunately I got distracted. More or less, the
sling-bundle-archetype or the sling-initial-content-archetype would be good
starting points, but neither are quite tailored to use with Sling CMS.

I'll put something together, I've been planning on doing a release with the
most recent updates for awhile now. I've created a ticket to make sure it's
tracked:
https://issues.apache.org/jira/browse/SLING-8762

Re: Different Login Landing Page

[Daniel Klco]

For the Sling CMS reference, I was able to set the jcr:root with
Sling-Initial-Content in an OSGi bundle:
https://github.com/apache/sling-org-apache-sling-app-cms/blob/master/ui/pom.xml
https://github.com/apache/sling-org-apache-sling-app-cms/blob/master/ui/src/main/resources/jcr_root/ROOT.json

For the reference CMS app I put together a vagrant script with Apache httpd
proxying and caching content from Apache Sling using mod_proxy and
mod_cache. You can find it here:

Re: [DISCUSSION] markdown support for Sling CMS

[Daniel Klco]

I just provided a PR against Flexmark to add OSGi support. Assuming that
gets merged and released, adding markdown support to Sling will be pretty
easy as it's just installing the flexmark-osgi and jsoup bundles and then
whatever code we want to wrap around it:

Re: [DISCUSSION] markdown support for Sling CMS

[Daniel Klco]

Unfortunately, I'm not going to be at adapt.to :-( wrong side of the pond.

So for commonmark, I'm assuming you're referring to this one here:

https://github.com/atlassian/commonmark-java

We could embed the JAR into a bundle to provide markdown support and the
implementation of the Sling Models and any other services. Let me take a
look at it in my copious free time ;-)

Re: [DISCUSSION] markdown support for Sling CMS

[Daniel Klco]

Hey Eugen,

Now that Sling CMS 0.9.0 is out I was thinking adding markdown support to
Sling CMS would be a great addition (in part because I have a use case for
it for filtered user generated content)

I've created an issue for it:

https://issues.apache.org/jira/browse/SLING-7819

Do you want to create a PR for integrating this? How can I help?

Thanks,
Dan

I've used markdown a fair bit and agree for text heavy use cases.

Totally. It'd seem like we'd need to include a markdown editor, script and
model to render the markdown content. That way we could show a HTML editor
and a markdown editor which might be nice from anyone coming from a
markdown too such as Jekyll.

That'd be great!

Re: SQL Resource Provider?

[Daniel Klco]

I've been down the path BTW Jason, fun may not be the best description ;-)
Granted this was about 4 years ago now so who knows what has changed. The
biggest problem I had, by far, was that the proprietary API I needed to use
was based on the assumption that it was dealing with JCR backed resources.

Re: Daily content sync between environments

[Daniel Klco]

On a similar vein, another fun one we did a while back was to vlt co into a
git repo and then blanket add and commit any changes on the hour. That way
we had a snapshot of exactly what was going on in the repository and the
ability to snapshot back any portion of the tree at any time (at a
reasonable granularity level). Very useful in the throes of authoring where
we were training up authors and trying to get a bunch of site content added
at the same time.

Re: Daily content sync between environments

[Daniel Klco]

I've used VLT for this as well. It's nice as you can target the path to
update but it is clunky. From a speed perspective, you could also use an S3
bucket to transfer the content if you are using AWS so each script only
cares about its local environment and you don't need to allow direct access
between servers.

Re: Bundle based JCR File

[Daniel Klco]

Hey Andreas,

Have you checked the log files? The Sling Content Importer will log any
errors encountered in installing content when the bundle is installed. In
general, that concept should be fine, but it would depend on the exact
structure.

There are a couple of Sling-based apps out there which do leverage bundle
content you may want to check out as examples:

https://github.com/auniverseaway/slick-2/tree/master/ui.apps
https://github.com/nateyolles/publick-sling-blog/tree/master/ui

Re: json support

[Daniel Klco]

Yep, this is supported via the Sling Content Importer:
https://sling.apache.org/documentation/bundles/content-loading-jcr-contentloader.html

As a note, you can do this via bundles or it is also supported via the
import operation in the Sling Post Servlet:
https://sling.apache.org/documentation/bundles/manipulating-content-the-slingpostservlet-servlets-post.html#importing-content-structures

Re: Sling Model and Request Parameters

[Daniel Klco]

Agreed, it'd be nice to have, but request parameters cannot be included in
the default injectors list for the reason which Stefan lists. Would it make
sense to use the @Source annotation and add support for injectors which are
not considered by default?

Re: Sling models adaptTo taglib

[Daniel Klco]

Roy,

You can pretty safely upgrade the version of Sling Taglibs without
upgrading the overall application version. If you include the newer version
of the bundle into your build package in a folder like
/apps/[app-name]/install, Sling will pick up the more recent version of the
bundle and install it. If you have any issues, you can force Sling to
recompile the JSP's from the OSGi console.

Regards,
Dan
