I am trying to inject the below script using frida
function main() {
Java.perform(function () {
let fhs = Java.use("com.tencent.mm.protocal.protobuf.fhs");
fhs.da.implementation = function (bArr) {
console.log('da is called' + ', ' + 'bArr: ' + bArr);
let ret = this.da(bArr);
console.log('da ret value is ' + ret);
return ret;
};
})}setImmediate(main)
Throws the below error
TypeError: cannot set property 'implementation' of undefined

Below one is the decompiled code of the apk file.
public final fhs da(byte[] bArr) {

I am using the calendar plugin for RoundCube Webmail, any time i am trying to create an event, I receive the following error:
[12-Apr-2022 17:56:08 UTC] PHP Fatal error: Uncaught TypeError: Sabre\VObject\Document::createProperty(): Argument #3 ($parameters) must be of type array, null given, called in /var/www/html/plugins/libcalendaring/libvcalendar.php on line 939 and defined in /usr/share/php/Sabre/VObject/Document.php:103
The functions:
public function createProperty($name, $value = null, array $parameters = null, $valueType = null){
// If there's a . in the name, it means it's prefixed by a groupname.
if (false !== ($i = strpos($name, '.'))) {
$group = substr($name, 0, $i);
$name = strtoupper(substr($name, $i + 1));
} else {
$name = strtoupper($name);
$group = null;
}
$class = null;
if ($valueType) {
// The valueType argument comes first to figure out the correct
// class.
$class = $this->getClassNameForPropertyValue($valueType);
}
if (is_null($class)) {
// If a VALUE parameter is supplied, we should use that.
if (isset($parameters['VALUE'])) {
$class = $this->getClassNameForPropertyValue($parameters['VALUE']);
if (is_null($class)) {
throw new InvalidDataException('Unsupported VALUE parameter for '.$name.' property. You supplied "'.$parameters['VALUE'].'"');
}
} else {
$class = $this->getClassNameForPropertyName($name);
}
}
if (is_null($parameters)) {
$parameters = [];
}
return new $class($this, $name, $value, $parameters, $group);
}
Call it:
$vdt = $cal->createProperty($name, $dt, null, $is_dateonly ? 'DATE' : 'DATE-TIME');
Does anyone know how to fix this?
I've created a Groovy script based Live Template for DataGrip, but it always throws a startup error but it works on online groove executor:
def result = '';
def i=1;
_1.split().eachWithIndex { item, index ->
def ans = '';
if (_2=='id' && index==0) {
return;
} else if (_2=='uuid' && index==0) {
ans = 'gen_random_uuid()';
} else {
ans = '$'+i;
i++;
}
if (index.next() != _1.split().size()) {
ans= ans + ','
}
result = result + ans
};
return result;
Here is the error:
startup failed:
Script1.groovy: 1: expecting '}', found 'if' # line 1, column 267.
'$' + i;
i++;
} if (index.

Solution is to put a semicolon after each if closes.
How would you call this library with Raku/Perl6's Native Call?
https://developer.gnome.org/gtk3/stable/gtk3-Clipboards.html#gtk-clipboard-request-text
void
gtk_clipboard_request_text (GtkClipboard *clipboard,
GtkClipboardTextReceivedFunc callback,
gpointer user_data);
Many thanks,
-T
Edit: this question was HOW to call the function. Not to troubleshoot a failed call. No code was written at this point.
The following seems to work:
use v6;
use NativeCall;
constant GdkAtom := uint64;
constant GDK_NONE = 0x0;
sub gtk_init(Pointer $argc, Pointer $argv) is native('gtk-3') { * };
sub gdk_display_get_default() returns Pointer is native('gdk-3') { * };
sub gtk_clipboard_get_for_display(Pointer $display, GdkAtom $selection)
returns Pointer is native('gtk-3') { * };
sub gtk_clipboard_request_text(
Pointer $clipboard,
&callback ( Pointer $clipbrd, Str $text, Pointer $data),
Pointer $user_data) is native('gtk-3') { * };
sub gtk_main() is native('gtk-3') { * };
sub gtk_main_quit() is native('gtk-3') { * };
gtk_init(Pointer, Pointer); # Pass NULL for arguments
my $display = gdk_display_get_default();
my $clipboard = gtk_clipboard_get_for_display( $display, GDK_NONE );
my $callback = my sub (Pointer $clipboard, Str $text, Pointer $data) {
say "In callback: Text = $text";
gtk_main_quit();
}
gtk_clipboard_request_text( $clipboard, &$callback, Pointer );
gtk_main();
This will print the text that is currently on the system's default clipboard.
I have a sample hive table created as
CREATE TABLE union_test(foo UNIONTYPE<int, double, array<string>, struct<a:int,b:string>>);
The data can be viewed as
SELECT foo FROM union_test;
The output is
{0:1}
{1:2.0}
{2:["three","four"]}
{3:{"a":5,"b":"five"}}
{2:["six","seven"]}
{3:{"a":8,"b":"eight"}}
{0:9}
{1:10.0}
the first field (tag) denotes the type of the union ( 0 for int, 1 for double, 2 for array etc).
My problem is if I found to select only those records where the union type is 2 (array), how should I frame my query?
There is no function in Hive to read data from UnionType. So i wrote 2 UDF´s. One to get Union tag (that you trying to do) and second to get struct from union as an example.
get_union_tag() function:

}
to use these UDF´s compile and create jar file. Than upload into hive (in my case HDInsight). Than just use
add jar wasb:///hive/HiveGUDF.jar;
CREATE TEMPORARY FUNCTION get_union_struct AS 'HiveUDF.GetUnionStruct';
before u run e.g.
SELECT get_union_tag(exposed) FROM test;
I'm try to make a sort delegate in C++/CLI, but, when I try to compile I recive this erro:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
here is the code sample of the error:
using namespace System;
using namespace System::Collections::Generic;
private ref class Program
{
private:
enum class tokens
{
teste,
lala,
blabla,
};
ref struct teste1
{
int linha;
tokens tk;
};
private:

return p1.tk.CompareTo(p2.tk);
}
public:

bool jump = false;
List<teste1^>^ lstTest = gcnew List<teste1^>();
Random ^rnd = gcnew Random();

}
};
int main(array<String^> ^args)
{

return 0;
}
I just whant to sort the list with the token 'lala' first, how I can make this, and, How I can solve this ???
Your List is of type List<test1^> (notice the ^ hat). So the Comparison<T> delegate you want is Comparison<teste1^>. Thus you'll want to change your AnonymousMethod1 as follows:
static int AnonymousMethod1(teste1 ^ p1, teste1 ^ p2)
{
return p1->tk.CompareTo(p2->tk);
}
And in C++/CLI you need to explicitly create your delegate:
Comparison<teste1 ^> ^ comparisonDelegate = gcnew Comparison<teste1 ^>(&AnonymousMethod1);
lstTest->Sort(comparisonDelegate);
