MediaWiki - restrict access to namespace - linux

Within MediaWiki 1.31.8, I need to restrict access to pages in a namespace so only members of a group would be able to use/view it.
The wiki has over 500 pages that begin with "MARKETING:"
I have created a namespace by adding this to LocalSettings.php:
"$wgExtraNamespaces =
array (104 => "MARKETING",
105 => "MARKETING_Talk");
I then installed Lockdown and added this line to LocalSettings.php:
$wgNamespacePermissionLockdown[MARKETING]['*'] = ['marketing'];
(I've seen some users have "marketing" as their group in the wiki "ListUsers" webpage)
I then went to test it in incognito (to avoid cookies error) with a dummy user that has no groups with the expectation that he won't have any privileges but it just didn't work. I've noticed that I can enter gibberish into the code above and it doesn't change anything or even throw logs. Would really appreciate the help, thanks ahead.
EDIT: SOLVED. Turns out since the marketing namespace is set with an array, I have had to use the syntax for an array:
$wgNamespacePermissionLockdown = array_fill( 104, 105, [ '*' => [ 'marketinhRW' ] ] );

You are confusing namespace names, IDs and constants. 104 is the namespace ID, MARKETING is the namespace name. Almost everything takes a namespace ID (not name) as key, $wgNamespacePermissionLockdown included.
Conventionally, you'd define a human-readable constant for the namespace ID, by putting define( 'NS_MARKETING', 104 ) somewhere in your configuration, and then write $wgNamespacePermissionLockdown[NS_MARKETING]['*'] = ['marketing']; which will index by ID. If you instead write $wgNamespacePermissionLockdown[MARKETING], since there is no MARKETING constant, PHP will assume you meant to write 'MARKETING', and treat it as a string, so there will be no permissions defined for the namespace ID.

Puppet - How to write yaml files based on Role/Profile method

I've added our infrastructure setup to puppet, and used roles and profiles method. Each profile resides inside a group, based on their nature. For example, Chronyd setup and Message of the day are in "base" group, nginx-related configuration is in "app" group. Also, on the roles, each profile is added to the corresponding group. For example for memcached we have the following:
class role::prod::memcache inherits role::base::debian {
include profile::app::memcache
}
The profile::app::memcached has been set up like this :
class profile::app::memcache {
service { 'memcached':
ensure => running,
enable => true,
hasrestart => true,
hasstatus => true,
}
}
and for role::base::debian I have :
class role::base::debian {
include profile::base::motd
include profile::base::chrony
}
The above structure has proved to be flexible enough for our infrastructure. Adding services and creating new roles could not been easier than this. But now I face a new problem. I've been trying to separate data from logic, write some yaml files to keep the data there, using Hiera version 5. Been looking through internet for a couple of days, but I cannot deduct how to write my hiera files based on the structure I have. I tried adding profile::base::motd to common.yaml and did a puppet lookup, it works fine, but I could not append chrony to common.yaml. Puppet lookup returns nothing with the following common.yaml contents :
---
profile::base::motd::content: This server access is restricted to authorized users only. All activities on this system are logged. Unauthorized access will be liable to prosecution.'
profile::base::chrony::servers: 'ntp.centos.org'
profile::base::chrony::service_enable: 'true'
profile::base::chrony::service_ensure: 'running'
Motd lookup works fine. But the rest, no luck. puppet lookup profile::base::chrony::servers returns with no output. Don't know what I'm missing here. Would really appreciate the community's help on this one.
Also, using hiera, is the following enough code for a service puppet file?
class profile::base::motd {
class { 'motd':
}
}
PS : I know I can add yaml files inside modules to keep the data, but I want my .yaml files to reside in one place (e.g. $PUPPET_HOME/environment/production/data) so I can manage the code with git.
The issue was that in init.pp file inside the puppet module itself, the variable $content was assigned a value. Removing the value fixed the problem.

Discord.js - Command to Remove All Users Containing Role

I know that you can remove certain roles from users, and remove all roles from a user, but I was thinking of doing the reverse. I looked at this guide, which provides a way to retrieve all of the people who have a specific role. It seems like you could manipulate the collection/map to go through each member and remove the role. However, I cannot seem to achieve this.
I've hard-coded the one specific role that I am targeting as well as the message that should trigger the command.
Current code that I've been trying out (only seems to be working if there's just one person assigned the role):
if (msg.startsWith('!new round')) {
//check for everyone and remove the role
//roleID is just the roleID number string; I've stated it outside the if loop, for other command use cases as well
let membersWithRole = message.guild.roles.cache.get(roleID).members;
console.log(membersWithRole);
for (let member of membersWithRole) {
let mem = member[1]
mem.roles.remove(role).catch(console.error);
message.reply("Everyone with the jail role is now back in the game!");
}
}
Bottom line: Given a collection of the list of "guild" members that have the specified role (provided in the guide), could I iterate through a list* in order to remove the role from each member?
*I haven't found said list containing the members, but it's probably the objects themselves, so the whole collection
you need to learn documentation of discord.js
and yes you can do it by looping through all members.
if(msg.startsWith('!new round')){
console.log('command used by '+msg.author);
let role =msg.guild.roles.cache.get(roleId);
role.members.each(member=>{
member.roles.remove(role);
});
console.log('removed role from all members');
}
and also if you want to remove role from all members, so why you are not just deleting the role?
delete role:
msg.guild.roles.cache.get(roleId).delete();

Active Directory/Ldap Get DataType or Syntax of specific attributes in NodeJS

I am able to query active-directory/ldap to get the user information along with custom attributes. However I would to know the underlying DataType/attributeSyntax for each of those attribute returned.
Another the problem is that the query will not return the attribute itself if it does not contain any value.
So if can get fetch the attributes and their respective DataTypes then it provides me flexibility to set a default value basing on the DataType while preparing the final output object.
Eg:
1. I query AD to find foo user with attributes givenName, mail, myCustom1, myCustom2
{
givenName : "foo foo",
mail : "foo#boo.com",
myCustom1 : "TRUE"
}
but may not contain myCustom2 because it is not holding the value in AD.
get syntax for attributes givenName, mail, myCustom1, myCustom2
{
givenName : unistring,
mail : unistring,
myCustom1 : boolean,
myCustom2 : integer,
}
using above I can map the first result and prepare the final object as
{
givenName : "foo foo"
mail : "foo#boo.com"
myCustom1 : "TRUE"
myCustom2 : //usingHelperFunctionGetDefaultValueFor -> myCustom2
}
Active Director does not return attributes that do not have values, so that's not just the LDAPjs library, that's just how AD works.
Every object has an attribute called allowedAttributes that will show you every valid attribute that the object can potentially have.
If you need it, allowedAttributesEffective will list every attribute that the current user has permissions to modify.
These are both constructed attributes, meaning you have to ask for them specifically, or else you won't get them. For example, when searching, you have the option to specify the attributes you want to get back. If you specify nothing, you will get every non-constructed attribute that has a value. If you want any constructed attributes, you have to add it specifically to that list.
That's just a list of attributes. It won't tell you the type. You have to look to the schema for that, which is more difficult. You have to do a search using the base DN of CN=Schema,CN=Configuration,DC=domain,DC=com, where "domain.com" is the root domain of your forest, which may or may not be the same as the domain you're searching. You could look at the subSchemaSubEntry attribute of any object to find the location of the schema, although it will usually be CN=Aggregate,CN=Schema,CN=Configuration,DC=domain,DC=com (note the added CN=Aggregate).
But anyway, each object in there will have an attribute called ldapDisplayName, which is the name of the attribute as it appears on objects.
So if you want to find details on the givenName attribute, you would search the schema for (ldapDisplayName=givenName). Then the oMSyntax attribute is an enum that will tell you the type. The enum values are shown here. For givenName, that would be 64, which is a Unicode string.
The only benefit to looking up the types like this is if you are expecting your code to be run on any AD environment. If your code will only ever be run in one environment, then you can save coding time and run time by just hard-coding the attributes you are looking for and their types.

Indexing Sitecore Item security and restricting returned search results

I have several roles defined, each with different restrictions to content and media items and I would like to restrict the search results that are returned based on the access rights of the currently logged in user, rather than displaying the result and the user then presented with an "Access Denied" page. Some content will obviously be accessible to extranet\anonymous so they should be returned for all users regardless.
The security follows the standard Sitecore practices so Role inheritance (roles within roles) will be used, so it will need to take this into account also.
I couldn't see anything in the Advanced Database Crawler module that would help and I've looked through the Sitecore Search and Indexing Guide (version 6.6 and version 7) but couldn't find any information about indexing the security applied to items. The following articles have some suggestions:
How can I set up a Lucene index in Sitecore that handles security correctly?
This feels "dirty" and has the potential for performance issues, particularly when there are a large number of items returned. Also, (see in the comments) the issue with paging results.
Security (aka Permissions) and Lucene - How ? Should it be done?
The above looks more realistic, and would filter out the results based on indexed security roles, there would obviously be a need to expand the roles to handle roles within roles. My concern here would be that we would need to handle denied permissions, when we specifically need to deny/restrict access for certain roles to content items (I know this is not recommended practice, but there is a very specific need to always deny).
I'm at the planning stage at the moment so with the release of Sitecore 7 today there is also the possibility to use the updated Lucene libraries and/or SOLR if that makes life easier - assuming of course that some of the modules like WebForms for Marketers and Email Campaign Manager are updated before too long.
What are the solutions that people are using for returning search results taking into account security? Any alternatives than the linked questions above? Maybe something in Sitecore 7 that I can leverage, the updated Lucene libraries or SOLR?
I'd prefer to keep this all "out of the box" Sitecore and not use other third party search products if at all possible.
A slight alternative to the suggestion from Klaus:
In Sitecore.ContentSeach.config you'll find a pipeline called contentSearch.getGlobalSearchFilters
Processors added to this pipeline will be applied to any query, so if we drop in one that applies a filter based on roles we're good.
ComputedField
To start, we want a computed field added to our index configuration:
<fields hint="raw:AddComputedIndexField">
<field fieldName="read_roles" returnType="stringCollection">Sitecore.ContentSearch.ComputedFields.ReadItemRoles,Sitecore.ContentSearch</field>
</fields>
NOTE the stored type is a collection of strings. We'll use it to index all the names of roles that can read an item.
Implementation
We have a base abstract class to handle the extraction of item security details
public abstract class ItemPermissions: IComputedIndexField
{
public string FieldName { get; set; }
public string ReturnType { get; set; }
public object ComputeFieldValue(IIndexable indexable)
{
var indexableItem = indexable as SitecoreIndexableItem;
if (indexableItem == null) return null;
var security = indexableItem.Item.Security;
return GetPermissibles(security);
}
protected abstract object GetPermissibles(ItemSecurity security);
}
We implement the above with the abstracted method
public class ReadItemRoles : ItemPermissions
{
protected override object GetPermissibles(ItemSecurity security)
{
var roles = RolesInRolesManager.GetAllRoles();
return roles.Where(security.CanRead).Select(r => r.Name);
}
}
NOTE There's obviously a performance impact here, this will reduce your indexing speed.
To reduce the impact, only add the the computed field to the index configuration for the index that contains secured content. E.g. If your web content is only accessed by the anonymous user it will add no benefit.
Pipeline
Add the entry in to the config
<contentSearch.getGlobalSearchFilters>
<processor type="Sitecore.ContentSearch.Pipelines.GetGlobalFilters.ApplyGlobalReadRolesFilter, Sitecore.ContentSearch" />
</contentSearch.getGlobalSearchFilters>
Implementation
Implement the pipeline filter to check the roles of the context user
public class ApplyGlobalReadRolesFilter : GetGlobalFiltersProcessor
{
public override void Process(GetGlobalFiltersArgs args)
{
var query = (IQueryable<SitecoreUISearchResultItem>)args.Query;
var userRoles = Context.User.Roles.Select(r => r.Name.Replace(#"\", #"\\"));
var predicate = PredicateBuilder.True<SitecoreUISearchResultItem>();
predicate = userRoles.Aggregate(predicate, (current, role) => current.Or(i => i["read_roles"].Contains(role)));
if(predicate.Body.NodeType != ExpressionType.Constant)
args.Query = query.Filter(predicate);
}
}
Summary
Create a ComputedField that returns a list of all valid roles for a given access right
Apply a pipeline processor to contentSearch.getGlobalSearchFilters to add a query filter to each search request.
Use the PredicateBuilder class to ensure the role names are OR'ed together
The big benefit here is that you take the hit at index time and the handling of item restriction is handled through a search query as normal. No need to worry about the facet numbers or search counts being incorrect.
You can restrict the roles you are checking to compute the field and you can vary the application of the pipeline filter. You can even take out the pipeline filter and just update your queries to filter when you require it.
NOTE The biggest problem with this set up is the requirement to re-index your content when security restrictions change. Should you be applying security restrictions to users themselves, you'll have to include additional computed fields.
Edit 02/06/2013
I was just tinkering with this in a project and realised that it was AND'ing the roles in the query. If a user had multiple roles assigned then both roles would have to have declared rights to the item. I've updated the pipeline processor to use the PredicateBuilder class to OR the roles. A check is also added to ensure the predicate is not a constant, this ensures the query is updated only if we have a filter to apply.
After some more searching around, the Linq to Sitecore article pointed me to the following lines of code:
var index = SearchManager.GetIndex("sitecore_master_index");
var context = index.CreateSearchContext(SearchSecurityOptions.EnableSecurityCheck))
Digging through Sitecore.ContentSearch.dll and Sitecore.ContentSearch.LuceneProvider.dll in dotPeek decompiler and the mention of the indexing.filterIndex.outbound pipeline in the Sitecore 7 Search document I found the following code:
Sitecore.ContentSearch.LuceneProvider.LuceneSearchReults
public IEnumerable<SearchHit<TElement>> GetSearchHits()
{
for (int idx = this.startIndex; idx <= this.endIndex; ++idx)
{
Document doc = this.context.Searcher.IndexReader.Document(this.searchHits.ScoreDocs[idx].Doc, (FieldSelector) this.fieldSelector);
if (!this.context.SecurityOptions.HasFlag((Enum) SearchSecurityOptions.DisableSecurityCheck))
{
string secToken = doc.GetField("_uniqueid").StringValue;
string dataSource = doc.GetField("_datasource").StringValue;
if (!string.IsNullOrEmpty(secToken))
{
bool isExcluded = OutboundIndexFilterPipeline.CheckItemSecurity(new OutboundIndexFilterArgs(secToken, dataSource));
if (!isExcluded)
yield return new SearchHit<TElement>(this.searchHits.ScoreDocs[idx].Score, this.configuration.IndexDocumentPropertyMapper.MapToType<TElement>(doc, this.selectMethod, this.virtualFieldProcessors, this.context.SecurityOptions));
}
}
else
yield return new SearchHit<TElement>(this.searchHits.ScoreDocs[idx].Score, this.configuration.IndexDocumentPropertyMapper.MapToType<TElement>(doc, this.selectMethod, this.virtualFieldProcessors, this.context.SecurityOptions));
}
}
Sitecore.ContentSearch.Pipelines.IndexingFilters
public class ApplyOutboundSecurityFilter : OutboundIndexFilterProcessor
{
public override void Process(OutboundIndexFilterArgs args)
{
if (args.IndexableUniqueId == null || !(args.IndexableDataSource == "Sitecore"))
return;
ItemUri uri = new ItemUri(args.IndexableUniqueId);
if (args.AccessRight != AccessRight.ItemRead || Database.GetItem(uri) != null)
return;
args.IsExcluded = true;
}
}
So it looks like Sitecore 7 gives us the ability to filter the the search results using the security rights of the context user straight out of the box, albeit using a very similar method of checking the item read permissions that Mark Cassidy suggested. Which is good news, since if this is a requirement for Sitecore 6 implementations then we can easily update the Advanced Database Crawler to do the same thing.
I'm still not convinced on the performance of this though, given that Sitecore 7 comes with Item Buckets and the possibility of storing millions of items. It should be possible to create several indexes though, and only EnableSecurityCheck on indexes with security enabled content, but then we need to think about combining the results from several indexes for "global search" results and also take into acccount Boosting which will mean re-ordering the combined results.
well - your considerations seems quite on target.
The easy implementation is to check the item through the database lookup - but paging, facetting and other statistics will fail in that.
The approach we do is to index security tokens for roles - having an inclusion field for allow and an exclusion field for deny rights. You then need to build a query for this - and expand all roles in roles for the query.
There are two issues you might be facing.
One is very complex OR queries for all roles in roles memberships. Might be less then well-performing.
The other is indexing congestion - as you will need to index major parts of the contentitems when security and permissions change as then are inherited.
The alternative is to use join queries - but normally that would be bad performing.
Sitecore developers made a silly mistake, it will never work, because of that statement:
if ((args.IndexableUniqueId != null) && (args.IndexableDataSource == "Sitecore"))
as args.IndexableDataSource will always be equal to "sitecore" not "Sitecore".
I'm currently upgrading big project to latest 7.2 Update and found out that silly mistake, oh Sitecore Devs usual mistakes :)

Codeigniter routing URL with product name to product id

I need to redirect the URLs like this http://mysite.com/store/store-name to http://mysite.com/stores/products/store-id. Note that i need to get the store id from the database. So is it possible to do db operations in routes.php?
And in documentation the syntax is give as $route['store/:any']. How to get the value of second parameter here which is mentioned as :any.
There's not really any good nor simple way of running database queries through the routes. You can however have in the beginning of the controller function a validation.
I asume your store-name is some sort of slug for the product? Basicly you can validate if value is numeric or not, and if not find by slug and then redirect.
config/routes.php
$route["store/(.*)"] = 'stores/products/$1';
/* () and $1 together passes the values */
controllers/stores.php
/* Class etc. */
function products($mix) {
if (is_numeric($mix))
$int_id = $mix;
else {
$row = $this->get_where('products', array('slug' => $mix))->row();
$this->load->helper('url');
redirect("stores/products/{$row->id}");
}
/* Do stuff with the $int_id */
}
This asumes that you have:
A table named products
A column named id that's your products id
A column named slug that that's based on your store-name
I may be a little late to the party, but I may have an alternative suggestion.
I use the following for my routes:
http://mysite.com/store/1/store-name
Reason being... Based on your method, if you create
http://mysite.com/store/store-name
but then after a period of time (of which no doubt Google has indexed your page) you decide for what ever reason you have to change the name of the store to "Wonderful store name", you would naturally change your link to
http://mysite.com/store/wonderful-store-name
Which kills your SEO and any index links.
My solution of using http://mysite.com/store/1/store-name means that you can change store-name to anything you want, but it will always reference 1 meaning the user will still see the related page.
Anything is possible with CodeIgniter routes. Its all in the way you code it. Routing in CI is really flexible. You can use regular expressions besides the standard CI wildcards (:any)(:num). You can even add prefixes or suffixes to the path variables if you have to like:
$route['store/(:any)'] = "redircontroller/redirfunction/$1";
// for instance the namelookup method of the mystores controller
$route['stores/products/(:any)'] = "mystores/namelookup/$1";
You get the second parameter(and third and so on) by defining the variables in your route value which get passed to the controller method you define. If 'products' in you new url is also a variant you should start your wildcard expression there instead. You could also pull parameters out of the url using the URI class ($this->uri->segment(n)).
You don't, however, do database operations in routes.php. You do your database operations in the controller where you route to. My guess is that you'll have to match the store id using whatever is used in the url in a query.
In any case the path that you are using the routes file for is the path the user will see. To do the redirect you have to accept the original path and then redirect the user to the new path like so:
// in some controller that's attached to the original url
public function redirfunct($var){
$this->load->helper('url');
redirect(base_url('stores/products/' . $var));
}
I hope this helps you.
Yes that is easy, you only need to show the ID instead of the name,
you must be doing like storeName> Click to view details
Make it as
storeId> Click to view details
and when you are passing the parameter to the database, change the check of mysql, change it to id instead of name , that can be some like
" select yourRequiredColumn from table_name where id=".parameter."
Thanks
