Do you know if a custom Firefox extension can read values setted calling GM_setValue() from a GraseMonkey user script?
These values exists in about:config, (enter "greasemonkey" in the filter).
Perhaps there exists an easier way to get them, though...
Since Greasemonkey 1.13 GM_setValue() uses an SQLite db to persist values.
This DB can be accessed directly (see https://github.com/greasemonkey/greasemonkey/blob/master/modules/miscapis.js).

Having an issue with the <distributed-cache> tag and Redis.
We have a <partial> Razor view that displays results of a long-running query. We acquire the data from a service injected in using #inject. The data updates very rarely, hence we wrap the content in a <distributed-cache> tag helper, with a long expires-after attribute.
However, when the data is finally updated (in another part of our app), we need to delete that key from the distributed cache, in order to force the page to update on next execution. (It's not possible for us to predict when the data will change - we can only respond to an external event.)
The problem we're having is that, despite having a fixed name attribute, the cache key appears to be impossible to predict. For example <distributed-cache name='_myQuery' vary-by-user='true'> creates a key something along the lines 7/za/Bc/ZRn/MsR/hG69TYTx1LEzqBvlyH1OLJgrpk4= in Redis.
How can I either:
Predict/calculate what the cache key is going to be in redis, so that I can delete it in another part of our application?;
Force the <distributed-cache> tag to ignore the cached value this one time? I know we have the enabled property, because this isn't going to work because the page doesn't know when to invalidate the cache.
After digging into the ASP.NET Core source I've found the CacheTagKey.cs file, which contains the GenerateKey() and GenerateHaskedKey() methods. These methods create the key from a bunch of params, then SHA256 hashes the key and returns base64.
So it looks like I can use this to predict the cache key and solve the issue.
I guess it's a simple question, but i still couldn't figure out how can i change the PDATA1/MiscData(0) property of an element via Add-In (and not by SQL Update). The problem is that the documentation says the MiscData is read-only.
Basically i am trying to make a hyper-link on a diagram with the help of an Add-In.
I create a simple Text typed EA.Element, then an EA.DiagramObject, connect them via ElementID and i need this Text typed object to point to an exact diagram.
What i know is that a hyper-link is a Text typed object with PDATA1 filled in with the wanted diagram's ID. The created element's Notes is already filled with a valid hyperlink's value like: packageName : diagramName.
I'm interested in any other ways to make a working hyper-link with the help of an Add-In.
Thanks in advance for the answer!

You need to call
Repository.Execute("UPDATE t_object set PDATA1 ...")
Execute is an undocumented but ever since working last resort. Nobody knows why MiscData is r/o.
In oder to make the changes visible on the diagram you need to call
Repository.ReloadDiagram (diagram.DiagramID)
Since EA will eventually pop-up a save-window for modified diagrams you should eventually call
Repository.SaveDiagram (diagram.DiagramID)
prior to the reload.
Important note: You need to remember that the Execute bypasses the API. If you have diagram changes and call Execute on diagram objects they need to be saved before. EA only updates all changed diagram objects in the database when the whole diagram is saved (manually or via SaveDiagram).
I have a User's information which I have stored in a Hash. I have his permission information stored in a Set.
I want to test for a condition on the Set, retrieve the Key and then fetch the actual Value using the retrieved Key from the Hash.
How can I do this?
Do I have to use Lua scripting to achieve the above goal or is there any other way?
You'll have to do it using multiple requests in that case. While Lua appears to be the way, your requirements - namely fetch a key based on the value of another key - rule out a single script since key names should be passed explicitly.
I had the same requirement and I couldn't find any other way to do this. Redis pipeline and transaction functions are other tools to execute multiple commands in single step but for your situation where you want to get a value and execute a command based on it, the only way remains is LUA!!
you can use a hash to handle user information and his permissions (in the same hash). In this case, when you have a userId you can retrieve the permissions with one shot by using userId and permissionKey. See example below, I put the permissions as string (in your case put it as Set):
redis> HSET userId permissionKey "perm1, perm2, perm3"
redis> HGET userId permissionKey
"perm1, perm2, perm3"
Hope this help you.
From the research I've done, it appears I need to send a special OID with my request (1.2.840.113556.1.4.417) in order to access the Deleted Objects container.
I couldn't find a way to send a specific control with a request using the "net-ldap" gem. Does anyone know if this is possible?
There is another gem, ruby-ldap, which appears to be more flexible and it seems I can send controls with my request (e.g. using the search_ext2() method).
However, no matter what I try, I am not getting back any objects, even though I know they haven't been garbage collected yet.
I'm including the filter "isDeleted=TRUE" with my requests as well.
OK, I finally figured it out. One will need to use the ruby-ldap gem. The reason my controls were not being sent was because the LDAP Protocol Version (LDAP::LDAP_OPT_PROTOCOL_VERSION) had defaulted to v2 and apparently it must be v3.
The following is a snippet that works:
require 'ldap'
conn = LDAP::Conn.new('yourserver.example.com', 389)
conn.set_option(LDAP::LDAP_OPT_PROTOCOL_VERSION, 3)
conn.bind("CN=Administrator,CN=Users,DC=example,DC=com", "sekritpass")
# controlType: 1.2.840.113556.1.4.417 (LDAP_SERVER_SHOW_DELETED_OID)
control = LDAP::Control.new('1.2.840.113556.1.4.417')
conn.search_ext2('CN=Deleted Objects,DC=example,DC=com', LDAP::LDAP_SCOPE_SUBTREE, "(isDeleted=*)", nil, false, [control], nil)
The filter (isDeleted=*) isn't necessarily required, you could also simply use (objectClass=*). You can also use the scope LDAP::LDAP_SCOPE_ONELEVEL if desired.
Have you tried isDeleted=* instead?

I have a table called settings, when I would change or enter data into the form it did not change the data in the table. In addition on form an image upload file is not running, There may be the wrong code below.
(Solved by me)
Maybe someone can help me Related to this.
What you are doing here is tottaly in secure and your data can be hacked / manipulate really fast.
Why dont you use a framework like codeignighter there are about 100 easy frameworks that will help you manage database a lot easyer.
Are you sure that you are updating the wrond ID? where id = 1, seems to be not dynamic.
Please post your error http://www.w3schools.com/php/func_mysql_error.asp
I know it is not so related to your question, but you should see these light frameworks:
http://kohanaframework.org/
https://github.com/ElbertF/Swiftlet
http://ellislab.com/codeigniter
You're not checking the return status of of your query, so if it's not working you wouldn't know. Do this:
mysql_query("UPDATE settings SET site='$name',keywords='$keys',descrp='$desc',email='$email',fbpage='$fbpage',twitter='$twitter',gplus='$gplus',disclaimer='$disclaimer',template='$template' WHERE id=1")
or die(mysql_error());
Note: mysql_*() is deprecated: you shouldn't use it. Use mysqli_*() or PDO instead.
Also: You are susceptible to an SQL Injection attack. You should escape your input variables with mysql_real_escape_string() (or the equivalent if you switch to mysqli), or consider moving to prepared statements.
