I have been running a SAP UI5 application for a year with out any problems. But today it changed and gave me Access-Control-Allow-Origin.
This the code. I have only tried to change the version but it does not help.
<script

data-sap-ui-xx-bindingSyntax="complex"
data-sap-ui-resourceroots='{"VendorApprovalComponent.DO_OrgTransord" : "./" }' >
</script>
The errors that I'm getting is the following.
XMLHttpRequest cannot load sapui5.netweaver.ondemand.com/1.38.12/resources/sap/ui/layout/library-preload.json.
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'CUSTOMERURL' is therefore not allowed access.

I am trying to install net-snmp from scratch to make snmpv3 to work on my computer.
I did install net-snmp and create the user, but when I want to make snmpget it reject me with snmpget: Unknown user name
To install net-snmp I followed the official guide
I did install the packages libperl-dev, snmp-mibs-downloader and snmp too using sudo apt-get install

Here is my persistant configuration file /var/net-snmp/snmpd.conf
createUser neutg SHA "password" AES passphrase
The command I run is :
snmpget -u neutg -A password -a SHA -X 'passphrase'
-x AES -l authPriv localhost -v 3 1.3.6.1.2.1.1
I don't understand why it do not take in count my user. (I did restart the snmpd after entering the user - multiple times!)
The version of net-snmp I use :
Thanks in advance :)
After many research I've found what the problem is.
snmpd was not taking in count my configuration files. I saw it using the command :
snmpd -Dread_config -H 2>&1 | grep "Reading" | sort -u
Which tells you which configurations files are loaded by snmpd.
You can see it as well looking at the configuration file /var/lib/snmp/snmpd.conf. When snmpd handle your users it creates special lines in the file. It looks like :
usmUser 1 3 0x80001f888074336938f74f7c5a00000000 "neutg" "neutg" NULL .1.3.6.1.6.3.10.1.1.3 0xf965e4ab0f35eebb3f0e3b30\
6bc0797c025821c5 .1.3.6.1.6.3.10.1.2.4 0xe277044beccd9991d70144c4c8f4b672 0x
usmUser 1 3 0x80001f888074336938f74f7c5a00000000 "myuser" "myuser" NULL .1.3.6.1.6.3.10.1.1.2 0x2223c2d00758353b7c3076\

setserialno 1424757026
So if you do not see any usmUser it's probably that your badly added your users.
The soluce
sudo /usr/local/sbin/snmpd -c /var/net-snmp/snmpd.conf -c /usr/local/share/snmp/snmpd.conf
When I run tests which fail I get a huge output with a lot of markup hiding the error.
Example:
$ perl script/my_prove.pl t/2410-topinfo.t
t/2410-topinfo.t .. 1/?
# Failed test '200 OK'
# at t/2410-topinfo.t line 12.

# Failed test 'similar match for selector "h1"'

# </pre>
#
# .... lots of lines follow here ............
The error seems to be a single line:
Can't call method "name" on an undefined value at template extern/topinfo/show.html.ep line 2
The test-script producing this output is:
use Mojo::Base -strict;
use Test::More;
use Test::Mojo;
use FindBin;
require "$FindBin::Bin/../script/ba_db";
my $t = Test::Mojo->new( 'BaDb' );
$t->ua->max_redirects(1);
$t->get_ok('/info/penx2')
->status_is(200)
->text_like('h1' => qr/\QFlatinfo Business-Apartment Hietzing\E/)
->content_like( qr/\QSelected language: German\E/ )
# ...
;
done_testing();
Is there a way to tell Mojolicious to respond without all this HTML-Markup so that I can see the error-mesage immediately?
There are two things at play here.
The large debug output with the full page source is because the content_like method from Test::Mojo didn't find a match, and it's telling you in which string it was looking. That's a convenience method, but if the page is large, it's a lot of text. This might tell you that the test failed because the content was wrong. But in this specific case it didn't.
The real problem is that the test failed because you had a syntax error. You can already see that from the very first test.
$t->get_ok('/info/penx2')
->status_is(200)
This test also failed. (It's a bit confusing for people who are used to Test::WWW::Mechanize because there get_ok will also check if the response was 200 OK).
# Failed test '200 OK'
# at t/2410-topinfo.t line 12.
# got: '500'
# expected: '200'
The actual error message should be there without all that HTML markup somewhere else, because while it was doing the get_ok it would have encountered the error, which should have gone to the application log. In a unit-test, that probably is STDERR.
I don't know if you've not included it, or if it's omitted. The log should be there too I believe.
Getting back to the HTML and the actual question, the reason it's output is because Test::Mojo's content_like (and most other of its methods) uses Test::More under hood. It just dispatches to like from Test::More and passes along the page content. This in turn will always display the full string it was matching against.
In recent Test::More versions, it already uses Test2 under the hood. The relevant part that outputs the full string is here.
Unfortunately there is not much you can do about it. I'd focus on finding out why it doesn't show a proper log during the unit tests (possibly because you didn't run prove with -v), and maybe find a way to make errors come out in color, which would make it easier to read. There is a color logger for the Dancer2 framework (which I maintain), but I can't find one for Mojo there wasn't one for Mojo.
Now there is Mojo::Log::Colored, which can color individual log lines based on their log level.
use Mojo::Log::Colored;
# Log to STDERR
$app->log(
Mojo::Log::Colored->new(
# optionally set the colors
colors => {
debug => "bold bright_white",
info => "bold bright_blue",
warn => "bold green",
error => "bold yellow",
fatal => "bold yellow on_red",
}
)
);
This will give you nice colorful output to the console. Here's an example script.
$ MOJO_LOG_LEVEL=debug perl -Mojo -MMojo::Log::Colored \
-e 'a(
"/" => sub {
app->log->$_("hello world") for qw/debug info warn error fatal/;
shift->render(text=>"ok");
})->log( Mojo::Log::Colored->new )->start' \
daemon
And the output if called with $ curl localhost:3000.
I'm having a hard time setting up the replication between PouchDB and Sync Gateway.
I tried to follow Couchbase's blog post, but I wasn't successfull, either.
I'm building an Ionic application with angular-pouchdb and ng-pouchdb.
Here's what I got figured out so far:
every time I call pouchCollection it either creates a new database with the given name, or gives you a reference of the already created database;
the Sync Gateway is responsible for authorization of each document. I'm running it now with the GUEST user enabled, with "admin_channels": ["*"], so everyone should be able to access everything, right?
CORS should be enable, since both the app and the server are running on the same machine (localhost)
to get replication in both ways, I should use db.sync(URL) (angular-pouchdb), where URL is something like http://localhost:4984/prospect/ (and prospect could be the DB name)
Here's my Sync Gateway config.json file:
{
"log": ["CRUD", "REST+", "Access"],
"facebook": {"register": true},
"CORS": {
"Origin": ["http://localhost:8100"],
"LoginOrigin": ["http://localhost:8100"],
"Headers": ["Content-Type"],
"MaxAge": 17280000
},
"databases": {
"prospect": {
"server": "walrus:",
"users": {
"GUEST": {"disabled": false, "admin_channels": ["*"]}
},
"sync":
`
function(doc, oldDoc) {
channel("everything");
}
`
}
}
}
Here's my Ionic code:
app.controller('MyCtrl', function($scope, pouchCollection) {
$scope.students = pouchCollection('students');
var URL = 'http://localhost:4984/prospect/';
$scope.students.$db.replicate.sync(URL);
// ...list the array in the view
}
Whenever I try to make the replication work, I get the following in the console when running for the first time:

(index):28 The above 404 is totally normal. PouchDB is just checking if a remote checkpoint exists.
Since the last line says it is normal, I assume everything is fine.
When I run the app in the browser and in the emulator, Sync Gateway says things like:
2015-09-14T19:54:04.913-03:00 HTTP: #001: GET /prospect/?_nonce=1442271244612
2015-09-14T19:54:18.730-03:00 HTTP: #002: GET /prospect/?_nonce=1442271258729
...

2015-09-14T19:56:13.376-03:00 HTTP: #050: PUT /prospect/_local/2_QcxPjLD.zmtOXa7VM8Gw==
To me, it looks like everything is working. But I can't get it to sync with the iOS emulator or in a different browser.
What am I missing?
For your Questions..
[2]: The * Star channel is the channel where every document is automatically added to that channel. Example, a guest user will be granted the * star channel where that gives you the open ended access so any user that gets * (star) will be able to see everything in the system.
[3]: You do not need to enable CORS as sync gateway is running on the same domain as your webapp. Enabling CORS allows web apps to access resources on other domains rather than the origin domain.
The LoginOrigin list protects access to the _session and _facebook endpoints.
[4]: To replicate your data, within the app.js file you would define a URL variable for sync, like:
var SYNC_GATEWAY_URL = 'http://127.0.0.1:4984/prospect/';
