I want to insert lttng - tracepoint("traceprovider_name"tracepoint_name" "$1"$2") statements with same tracepoint_name and traceprovider_name but want to use different tracepoint signature in the code: for example:
TRACEPOINT_EVENT(
provider_name_test,
tp_name_tp,
TP_ARGS(
int, my_integer_arg, char*, my_string_arg
),
TP_FIELDS(
ctf_string(my_string_field, my_string_arg)
ctf_integer(int, my_integer_field, my_integer_arg)
)
)
------------------------------------------------------------------------
with the above defined traceprovider I can use:
tracepoint(provider_name_test, tp_name_tp,23, "hi there")
I want tracepoint() signatures as below
tracepoint(provider_name_test, tp_name_tp,23 )
tracepoint(provider_name_test, tp_name_tp,"hi there" )
The traceprovider name and tracepoint name have to unique in order to maintain fine granularity required for root cause analysis.So it should be unique but you can use the same tracepoints in multiple places.

Apologies for a length post. I have been trying to beat my head around reading about mock, MagicMock, and all the time getting confused. Hence, decided to write this post.
I know several questions, and pages have been written on this. But, still not able to wrap my head around this.
My Setup:
All the test code, and the 2 module files come under one "folder" mymodule
my_module_1.py file contains
class MyOuterClass(object):
MyInnerClass(object):
attribute1: str
attribute2: str
attribute3: str
def get(self) -> MyInnerClass:
'''
pseudocode
1. a call to AWS's service is made
2. the output from call in step 1 is used to set attributes of this InnerClass
3. return innerclass instance
'''
I use the OuterClass in another file(my_module_2.py), to set some values and return a string as follows:
class MyModule2():
def get_foo(self, some_boolean_predicate):
if some_boolean_predicate:
temp = my_module_1.OuterClass().get()
statement = f'''
WITH (
BAR (
FIELD_1 = '{temp.attribute1}',
FIELD_2 = '{temp.attribute2}',
FIELD_3 = '{temp.attribute3}'
)
)
'''
else:
statement = ''
return statement
I want to write the unit tests for the file my_module_2.py file, and test the function get_foo
How I am writing the tests(or planning on)
a test file by name test_my_module2.py
I started with creating a pytest.fixture for the MyOuterClass's get function as follows since I will be reusing this piece of info again in my other tests
#pytest.fixture
def mock_get(mocker: MockerFixture) -> MagicMock:
return mocker.patch.object(MyOuterClass, 'get')
Finally,
Then I proceeded to use this fixture in my test as follows:
from unittest import mock
from unittest.mock import MagicMock, Mock, patch, PropertyMock
import pytest
from pytest_mock import MockerFixture
from my_module.my_module_1 import myOuterClass
def test_should_get_from_inner_class(self, mock_get):
# mock call to get are made
output = mock_get.get
#update the values for the InnerClass's attributes here
output.attribute1.side_effect = 'attr1'
output.attribute2.side_effect = 'attr2'
output.attribute3.side_effect = 'attr3'
mock_output_str = '''
WITH (
BAR (
FIELD_1 = 'attr1',
FIELD_2 = 'attr2',
FIELD_3 = 'attr3'
)
)
'''
module2Obj = MyModule2()
response = module2Obj.get_foo(some_boolean_predicate=True)
# the following assertion passes
assert mock_get.get.called_once()
# I would like match `response to that with mock_output_str instance above
assert response == mock_output_str
But, the assertion as you might have guessed failed, and I know I am comparing completely different types, since I see
errors such as
FAILED [100%]
WITH (
BAR (
FIELD1 = '<MagicMock name='get().attr1' id='4937943120'>',
FIELD3 = '<MagicMock name='get().attr2' id='4937962976'>',
FIELD3 = '<MagicMock name='get().attr3' id='4937982928'>'
)
)
Thank you for being patient with me till here, i know its a really lengthy post, but stuck on this for a few days, ended up creating a post here.
How do i get to validate the mock's value with the mock_output_str?
yess! the hint was in the #gold_cy's answer. I was only calling my mock and never setting its values
this is what my test case ended up looking
mock_obj = OuterClass.InnerClass()
mock_obj.attribute1='some-1'
mock_obj.attribute2='some-2'
mock_obj.attribute3='some-3'
mock_get.return_value = mock_obj
once my mock was setup properly, then the validation became easy! Thank you!
I'm porting my Swift app to Flutter and for localising it I'm following this https://github.com/billylev/flutter_localizations but I can't see how to insert placeholder to insert a value in the translated values.
Basically the guide uses
String text(String key) {
return _localisedValues[key] ?? "$key not found";
}
to get the corresponding key:value pair from a .json file as
{
"Shop": "Negozio",
}
I just pass it in the Textwidget as :
Text(AppLocalizations.instance.text('Shop')).
How to modify text to insert one or more placeholders and how would be the .json be constructed?
Say for the value "User": "User" I'd like to insert a value after the transaction I can simply use a string sum and add the value as `Text(
AppLocalizations.instance.text('User') + ' ${widget.user.name}', but if I need to insert a value in the middle of the translated sentence, eg a message, I don't see how to accomplish it.
I need it to make localised versions of incoming push notification, and they have args.
In Swift I have it like this:
"ORDER_RECEIVED_PUSH_TITLE" = "Order number: %#";
"ORDER_RECEIVED_PUSH_SUBTITLE" = "Shop: %#";
"ORDER_RECEIVED_PUSH_BODY" = "Thank you %#! We received your order and we'll let you know when we start preparing it and when it's ready. Bye";
Any suggestions on how to accomplish that in Flutter?
Many thanks
I was suggested this package https://pub.dev/packages/sprintf#-installing-tab- and it works just as I needed. Sprintf just lets you specify one or more placeholders in a String and pass an array of args.
https://developermemos.com/posts/using-sprintf-flutter-dart. for more info, even this is pretty much it. So for example
"ORDER_RECEIVED_PUSH_TITLE" = "Order number: %#";
in the .json file would be :
{
"ORDER_RECEIVED_PUSH_TITLE": "Oder number: %s"
}
and using it would be
String orderNumber = 'some uuid';
Text(Sprintf(AppLocalitazions.instance.text('ORDER_RECEIVED_PUSH_TITLE'),[orderNumber]);
Hope this helps others.
we have a scala application that read lines from text file and process them using Akka Stream. for better performance we set parallelism to 5. the problem is if the multiple lines contains the same email we only keep one of the line and treated others as duplicated and throw error. I tried to use a java concurrentHashMap to detect duplication but it didn't work, here is my code:
allIdentifiers = new ConcurrentHashMap[String, Int]()
Source(rows)
.mapAsync(config.parallelism.value) {
case (dataRow, index) => {
val eventResendResult: EitherT[Future, NonEmptyList[ResendError], ResendResult] =
for {
cleanedRow <- EitherT.cond[Future](
!allIdentifiers.containsKey(dataRow.lift(emailIndex)), {
allIdentifiers.put(dataRow.lift(emailIndex),index)
dataRow
}, {
NonEmptyList.of(
DuplicatedError(
s"Duplicated record at row $index",
List(identifier)
)
)
}
)
_ = logger.debug(
LoggingMessage(
requestId = RequestId(),
message = s"allIdentifiers: $allIdentifiers"
)
)
... more process step ...
} yield foldResponses(sent)
eventResendResult
.leftMap(errors => ResendResult(errors.toList, List.empty))
.merge
}
}
.runWith(Sink.reduce { (result1: ResendResult, result2: ResendResult) =>
ResendResult(
result1.errors ++ result2.errors,
result1.results ++ result2.results
)
})
we have config.parallelism.value set to 5, means any moment it'll process up to 5 lines concurrently. what I observed is if there are duplicated lines right next to each other, it didn't work, example:
line 0 contains email1
line 1 contains email1
line 2 contains email2
line 3 contains email2
line 4 contains email3
from the log i see the concurrentHashMap was populated with entries, but all lines passed the duplication detect and moved to the next process step.
so Akka Stream's parallelism is not the same thing as java's multithreads? how can i detect duplicated line in this case?
The problem is in the following snippet:
cleanedRow <- EitherT.cond[Future](
!allIdentifiers.containsKey(dataRow.lift(emailIndex)), {
allIdentifiers.put(dataRow.lift(emailIndex),index)
dataRow
}, {
NonEmptyList.of(
DuplicatedError(
s"Duplicated record at row $index",
List(identifier)
)
)
}
)
In particular: imagine two threads simultaneously processing an email which should be deduplicated. It is possible for the following to happen (in order)
The first thread checks containsKey and finds the email is not in the map
The second thread checks containsKey and finds the email is not in the map
The first thread adds the email to the map (based on results from step 1.) and passes the email through
The second thread adds the email to the map (based on results from step 3.) and passes the email through
In other words: you need to atomically check the map for the key and update it. This is a pretty common sort of thing to want, so it is exactly what ConcurrentHashMap's put does: it updates the value at the key and returns the previous value it replaced, if there was one.
I'm not too familiar with the combinators in Cats, so the following might not be idiomatic. However, note how it inserts and checks for a previous value in one atomic step.
cleanedRow <- EitherT(Future.successful {
val previous = allIdentifiers.put(dataRow.lift(emailIndex), index)
Either.cond(
previous != null,
dataRow,
NonEmptyList.of(
DuplicatedError(
s"Duplicated record at row $index",
List(identifier)
)
)
)
})
I am trying to write a macro for debug print in the Nim language.
Currently this macro adds filename andline to the output by instantiationInfo().
import macros
macro debugPrint(msg: untyped): typed =
result = quote do:
let pos = instantiationInfo()
echo pos.filename, ":", pos.line, ": ", `msg`
proc hello() =
debugPrint "foo bar"
hello()
currently output:
debug_print.nim:9: foo bar
I would like to add the name of the procedure (or iterator) of the place where the macro was called.
desired output:
debug_print.nim:9(proc hello): foo bar
How can I get the name of procedure (or iterator) in Nim, like __func__ in C?
At runtime you can do getFrame().procname, but it only works with stacktrace enabled (not in release builds).
At compile-time surprisingly I can't find a way to do it. There is callsite() in macros module, but it doesn't go far enough. It sounds like something that might fit into the macros.LineInfo object.
A hacky solution would be to also use __func__ and parse that back into the Nim proc name:
template procName: string =
var name: cstring
{.emit: "`name` = __func__;".}
($name).rsplit('_', 1)[0]
building on answer from #def- but making it more robust to handle edge cases of functions containing underscores, and hashes containing trailing _N or not
also using more unique names as otherwise macro would fail if proc defines a variable name
import strutils
proc procNameAux*(name:cstring): string =
let temp=($name).rsplit('_', 2)
#CHECKME: IMPROVE; the magic '4' chosen to be enough for most cases
# EG: bar_baz_9c8JPzPvtM9azO6OB23bjc3Q_3
if temp.len>=3 and temp[2].len < 4:
($name).rsplit('_', 2)[0]
else:
# EG: foo_9c8JPzPvtM9azO6OB23bjc3Q
($name).rsplit('_', 1)[0]
template procName*: string =
var name2: cstring
{.emit: "`name2` = __func__;".}
procNameAux(name2)
proc foo_bar()=
echo procName # prints foo_bar
foo_bar()
NOTE: this still has some issues that trigger in complex edge cases, see https://github.com/nim-lang/Nim/issues/8212

FailureHandling.STOP_ON_FAILURE)
println(TC_1_called[inlinetextofusername])
println(TC_1_called[inlinetextofpassword]
I am getting following error:-
12-11-2017 04:31:40 PM - [ERROR] - Test Cases/01_UserManagement/Logout FAILED because (of) Variable 'inlinetextofusername' is not defined for test case.
How to take the values which is stored in Map in Test case 1 and to use in Test Case 2.
Map TC_1_called = WebUI.callTestCase(findTestCase('01_UserManagement/Login'), [('username') : 'Anna', ('password') : 'Analyst_2017',('map'):''],
FailureHandling.STOP_ON_FAILURE)
This returns values..
If you want to pass values from one test case to another in Katalon Studio, you should pass these values from Test Case A to Test Case B
Imagine you have these test cases Log in test and Dashboard test and you need to pass username and email from Log in testto Dashboard test
Go to script mode in Log in test and at the end of script add this line of code
WebUI.callTestCase( findTestCase('Test Cases/dashboard test') , [('username'): username, ('email'):email] )
This will pass local variables username and email from Log in test script to dashboard test
Notice: before applying this method, you should create test case variables to the second test case dashboard test from variables tab beside script tab in the lower section of test case editor.
Hope this comes in handy
I have issue on passing variable that has a random value to another test case.
Solution: I created a Global Variable with empty string then I set that Global Variable on my testCase_1 with a random value. I can now call that Global Variable to my testCase_2 without calling testCase_1. But you must execute testCase_1 first on your test suite.
testCase_1:
GlobalVariable.randomString = yourRandomValue
testCase_2:
String variableFromTestCase_1 = GlobalVariable.randomString
