I've been constructing a packet analising system for wireshark with Lua script.
Now I'm managing three following lua files where VPS.lua and DSS.lua are importing some functions from DSS_function.lua by require module.
VPS.lua DSS.lua DSS_function.lua
Question is how to know which file, VPS.lua or DSS.lua, DSS_function.lua are imported from.
DSS_function.lua has to know this information, because each time it declares the protocol depending on the file which is importing itself.
Thank you.
You can use something along these lines to figure out where a library is required from:
local name = debug.getinfo(3).short_src
if name:find "foo.lua" then
print("Required from Foo")
elseif name:find "bar.lua" then
print("Required from Bar")
end
But the problem is that it will only work the first time because Lua caches modules after the first time they are required.
Setting that aside, what you are trying to build is an abomination and whatever reason you think you have for wanting this is just a sign of a deeper problem with your code structure.
If you use require("name_of_the_Lua_file") then the return of the required Lua file goes to...
package.loaded.name_of_the_Lua_file
The next require("name_of_the_Lua_file") looks for this name in package.loaded.name_of_the_Lua_file and if there it loads it from there.
Only if the Lua file dont return anything then package.loaded.name_of_the_Lua_file returns a: true
...and not what you expected.
Example what i mean...
package.loaded.example={test = function() print "Hi - I am a test" end}
require('example').test()
-- Output: Hi - I am a test
So, check what is allready required with a look in package.loaded.
It could look like...
if package.loaded.example ~= nil then
print("Already loaded")
return true
else
print("Not exists - Load it first")
return false
end
-- Output: Already loaded
-- true

I love testing-library, have used it a lot in a React project, and I'm trying to use it in an Angular project now - but I've always struggled with the enormous error output, including the HTML text of the render. Not only is this not usually helpful (I couldn't find an element, here's the HTML where it isn't); but it gets truncated, often before the interesting line if you're running in debug mode.
I simply added it as a library alongside the standard Angular Karma+Jasmine setup.
I'm sure you could say the components I'm testing are too large if the HTML output causes my console window to spool for ages, but I have a lot of integration tests in Protractor, and they are SO SLOW :(.
I would say the best solution would be to use the configure method and pass a custom function for getElementError which does what you want.
You can read about configuration here: https://testing-library.com/docs/dom-testing-library/api-configuration
An example of this might look like:
configure({
getElementError: (message: string, container) => {
const error = new Error(message);
error.name = 'TestingLibraryElementError';
error.stack = null;
return error;
},
});
You can then put this in any single test file or use Jest's setupFiles or setupFilesAfterEnv config options to have it run globally.
I am assuming you running jest with rtl in your project.
I personally wouldn't turn it off as it's there to help us, but everyone has a way so if you have your reasons, then fair enough.
1. If you want to disable errors for a specific test, you can mock the console.error.
it('disable error example', () => {
const errorObject = console.error; //store the state of the object
console.error = jest.fn(); // mock the object
// code
//assertion (expect)
console.error = errorObject; // assign it back so you can use it in the next test
});
2. If you want to silence it for all the test, you could use the jest --silent CLI option. Check the docs
The above might even disable the DOM printing that is done by rtl, I am not sure as I haven't tried this, but if you look at the docs I linked, it says
"Prevent tests from printing messages through the console."
Now you almost certainly have everything disabled except the DOM recommendations if the above doesn't work. On that case you might look into react-testing-library's source code and find out what is used for those print statements. Is it a console.log? is it a console.warn? When you got that, just mock it out like option 1 above.
UPDATE
After some digging, I found out that all testing-library DOM printing is built on prettyDOM();
While prettyDOM() can't be disabled you can limit the number of lines to 0, and that would just give you the error message and three dots ... below the message.
Here is an example printout, I messed around with:
TestingLibraryElementError: Unable to find an element with the text: Hello ther. This could be because the text is broken up by multiple elements. In this case, you can provide a function for your text matcher to make your matcher more flexible.
...
All you need to do is to pass in an environment variable before executing your test suite, so for example with an npm script it would look like:
DEBUG_PRINT_LIMIT=0 npm run test
Here is the doc
UPDATE 2:
As per the OP's FR on github this can also be achieved without injecting in a global variable to limit the PrettyDOM line output (in case if it's used elsewhere). The getElementError config option need to be changed:
dom-testing-library/src/config.js
// called when getBy* queries fail. (message, container) => Error
getElementError(message, container) {
const error = new Error(
[message, prettyDOM(container)].filter(Boolean).join('\n\n'),
)
error.name = 'TestingLibraryElementError'
return error
},
The callstack can also be removed
You can change how the message is built by setting the DOM testing library message building function with config. In my Angular project I added this to test.js:
configure({
getElementError: (message: string, container) => {
const error = new Error(message);
error.name = 'TestingLibraryElementError';
error.stack = null;
return error;
},
});
This was answered here: https://github.com/testing-library/dom-testing-library/issues/773 by https://github.com/wyze.
I have added a custom locator in protractor, below is the code
const customLocaterFunc = function (locater: string, parentElement?: Element, rootSelector?: any) {
var using = parentElement || (rootSelector && document.querySelector(rootSelector)) || document;
return using.querySelector("[custom-locater='" + locater + "']");
}
by.addLocator('customLocater', customLocaterFunc);
And then, I have configured it inside protractor.conf.js file, in onPrepare method like this:
...
onPrepare() {
require('./path-to-above-file/');
...
}
...
When I run my tests on the localhost, using browser.get('http://localhost:4200/login'), the custom locator function works absolutely fine. But when I use browser.get('http://11.15.10.111/login'), the same code fails to locate the element.
Please note, that the test runs, the browser gets open, user input gets provided, the user gets logged-in successfully as well, but the element which is referred via this custom locator is not found.
FYI, 11.15.10.111 is the remote machine (a virtual machine) where the application is deployed. So, in short the custom locator works as expected on localhost, but fails on production.
Not an answer, but something you'll want to consider.
I remember adding this custom locator, and encounter some problems with it and realised it's just an attribute name... nothing fancy, so I thought it's actually much faster to write
let elem = $('[custom-locator="locator"]')
which is equivalent to
let elem = element(by.css('[custom-locator="locator"]'))
than
let elem = element(by.customLocator('locator'))
And I gave up on this idea. So maybe you'll want to go this way too
I was able to find a solution to this problem, I used data- prefix for the custom attribute in the HTML. Using which I can find that custom attribute on the production build as well.
This is an HTML5 principle to prepend data- for any custom attribute.
Apart from this, another mistake that I was doing, is with the selector's name. In my code, the selector name is in camelCase (loginBtn), but in the production build, it was replaced with loginbtn (all small case), that's why my custom locater was not able to find it on the production build.
I am working on a project which incorporates C code, as well as (MASM-like) assembly. I want to be able to compile it on Linux, as well as Windows, thus I am using a third-party assembler (jwasm) as follows:
QMAKE_PRE_LINK += jwasm -coff -Fo$$assembly_obj $$PWD/assembly.asm
(here, assembly_obj holds the directory I want jwasm to save the output. Oh, by the way: when using jwasm it is critical to first specify all the parameters, and only at the end the input files, otherwise it will ignore the parameters)
To make it easier for other people to compile the project, I would like to be able to check if jwasm is in their path, and if not, emit an error() telling them how to fix this. However, I am not sure if this is even possible using qmake. I have tried:
exists("jwasm") { # Always false
message("jwasm found!")
}
as well as:
packagesExist(jwasm) { # Always true
message("jwasm found!")
}
I have looked around in the qmake docs, but couldn't find any other alternatives...
I need to customize other's code,
so I found they used
Mage::getSingleton('core/session')->getMyCustomBlockInfo();
in Order.php file for custom order email
so I can't find this function getMyCustomBlockInfo();
Can anyone tell me where this function reside?
Thanks
those are magic functions get() and set() and you are asking a session variable there that is set as
Mage::getSingleton('core/session')->setMyCustomBlockInfo();
somewhere in your code. If you use terminal you can easily find by making a following grep:
grep '>setMyCustomBlockInfo(' . -rsni
and it will list the files where your variable is set to session.
example :
Mage::getModel('catalog/product'); //or
Mage::getSingleton('catalog/product');
the code must be in '../app/core/Mage/Catalog/Model/Product.php' file
then
Mage::getSingleton('core/session');
the code must be in '../app/core/Mage/Core/Model/Session.php' file
because the class Mage_Core_Model_Session's parent::parent is Varien_Object, then you can do all magic functions and you can ->getData() to see the Data inside.
Mage::getSingleton('core/session')->getData();
on your problem when go call ->getData() you can see data : [my_custom_block_info]
you can set it with call
Mage::getSingleton('core/session')->setMyCustomBlockInfo('what');
Mage::getSingleton('core/session')->getMyCustomBlockInfo();
// will return 'what'
I am looking to utilize the ICU library for transliteration, but I would like to provide a custom transliteration file for a set of specific custom transliterations, to be incorporated into the ICU core at compile time for use in binary form elsewhere. I am working with the source of ICU 4.2 for compatibility reasons.
As I understand it, from the ICU Data page of their website, one way of going about this is to create the file trnslocal.mk within ICUHOME/source/data/translit/ , and within this file have the single line TRANSLIT_SOURCE_LOCAL=custom.txt.
For the custom.txt file itself, I used the following format, based on the master file root.txt:
custom{
RuleBasedTransliteratorIDs {
Kanji-Romaji {
file {
resource:process(transliterator){"custom/Kanji_Romaji.txt"}
direction{"FORWARD"}
}
}
}
TransliteratorNamePattern {
// Format for the display name of a Transliterator.
// This is the language-neutral form of this resource.
"{0,choice,0#|1#{1}|2#{1}-{2}}" // Display name
}
// Transliterator display names
// This is the English form of this resource.
"%Translit%Hex" { "%Translit%Hex" }
"%Translit%UnicodeName" { "%Translit%UnicodeName" }
"%Translit%UnicodeChar" { "%Translit%UnicodeChar" }
TransliterateLATIN{
"",
""
}
}
I then store within the directory custom the file Kanji_Romaji.txt, as found here. Because it uses > instead of the → I have seen in other files, I converted each entry appropriately, so they now look like:
丁 → Tei ;
七 → Shichi ;
When I compile the ICU project, I am presented with no errors.
When I attempt to utilize this custom transliterator within a testfile, however (a testfile that works fine with the in-built transliterators), I am met with the error error: 65569:U_INVALID_ID.
I am using the following code to construct the transliterator and output the error:
UErrorCode status = U_ZERO_ERROR;
Transliterator *K_R = Transliterator::createInstance("Kanji-Romaji", UTRANS_FORWARD, status);
if (U_FAILURE(status))
{
std::cout << "error: " << status << ":" << u_errorName(status) << std::endl;
return 0;
}
Additionally, a loop through to Transliterator::countAvailableIDs() and Transliterator::getAvailableID(i) does not list my custom transliteration. I remember reading with regard to custom converters that they must be registered within /source/data/mappings/convrtrs.txt . Is there a similar file for transliterators?
It seems that my custom transliterator is either not being built into the appropriate packages (though there are no compile errors), is improperly formatted, or somehow not being registered for use. Incidentally, I am aware of the RuleBasedTransliterator route at runtime, but I would prefer to be able to compile the custom transliterations for use in any produced binary.
Let me know if any additional clarification is necessary. I know there is at least one ICU programmer on here, who has been quite helpful in other posts I have written and seen elsewhere as well. I would appreciate any help I can find. Thank you in advance!
Transliterators are sourced from CLDR - you could add your transliterator to CLDR (the crosswire directory contains it in XML format in the cldr/ directory) and rebuild ICU data. ICU doesn't have a simple mechanism for adding transliterators as you are trying to do. What I would do is forget about trnslocal.mk or custom.txt as you don't need to add any files, and simply modify root.txt - you might file a bug if you have a suggested improvement.
