QUESTION
While testing handling of const object members I ran into this apparent bug in clang. The code works in msvc and gcc. However, the bug only appears with non-consts which is certainly the most common use. Am I doing something wrong or is this a real bug?
ANSWER
Answered 2022-Apr-15 at 19:32Your game of "construct a new object in place of the old one" is the problem.
- It is completely forbidden if the object is
constor contains anyconstmember subobjects.
due to the following rule in [basic.life] (note that a rewrite1 of this rule is proposed in post-C++17 drafts)
If, after the lifetime of an object has ended and before the storage which the object occupied is reused or released, a new object is created at the storage location which the original object occupied, a pointer that pointed to the original object, a reference that referred to the original object, or the name of the original object will automatically refer to the new object and, once the lifetime of the new object has started, can be used to manipulate the new object, if:
- the storage for the new object exactly overlays the storage location which the original object occupied,
and
- the new object is of the same type as the original object (ignoring the top-level cv-qualifiers)
and
- the type of the original object is not const-qualified, and, if a class type, does not contain any non-static data member whose type is const-qualified or a reference type
and
- the original object was a most derived object of type
Tand the new object is a most derived object of typeT(that is, they are not base class subobjects).
You have to abide by this rule for the purposes both of return *this; and also the implicit destructor call.
- It also doesn't work during
constexprevaluation.
... this one is specific to the fact that std::string small-string optimization may be implemented using a union, and changing an active union member has been forbidden during constexpr evaluation, although this rule too seems to have changed post-C++17.
1 I consider said change to be misguided (it doesn't even permit the pattern it was supposed to fix) and break legitimate coding patterns. While it's true that a pointer to const-qualified object only made my view readonly and did not let me assume that the object wasn't being changed by someone else holding a pointer/reference that wasn't so qualified, in the past if I was given a pointer (qualified or not) to an object with a const member, I was assured that no one was changing that member and I (or my optimizing compiler) could safely use a cached copy of that member (or data derived from that member value, such as a hash or a comparison result).
Apparently this is no longer true.
While changing the language rule may automatically remove all compiler optimizations that would have assumed immutability of a const member, there's no automatic patch to user-written code which was correct and bug-free under the old rules, for example std::map and std::unordered_map code using std::pair. Yet the DR doesn't appear to have considered this as a breaking change...
I was asked for a code snippet that illustrates a behavior change of existing valid code, here it is. This code was formerly illegal, under the new rules it's legal, and the map will fail to maintain its invariants.
QUESTION
I have class city:
...ANSWER
Answered 2022-Mar-06 at 13:22It's because when you start the WebApi, and send a real request to it, behind the scenes it calls several methods in which it's validating your request, before it calls your controller action. In those methods it's setting the ModelState.IsValid property to false. On the other hand when you call your controller action directly from tests, nothing validates your request, hence your ModelState.IsValid is set to true by default.

UPDATE: I have added the dput() input at the bottom of the post.
I have a large dataset of tweets that I would like to subset by month and year.
data_cleaning$date <- as.Date(data_cleaning$created_at, tryFormats = c("%Y-%m-%d", "%Y/%m/%d"), optional = FALSE)
I used the line of code above to format the date variable in the dataframe below.
ANSWER
Answered 2022-Feb-07 at 21:17# set as data.table
setDT(data_cleaning)
# create year month column
data_cleaning[, year_month := substr(date, 1, 7)]
# split and put into list
split(data_cleaning, data_cleaning$year_month)

Objective:
I want to create a stack histogram of a PaperlessBilling categorical feature (Telco Customer Churn dataset), display the Y axis as a percentage and display the churn distribution as the hue. But, the percentage is not from the accumulative calculation.
Here is what I expected if using R:
...ANSWER
Answered 2021-Dec-05 at 14:56With stat="percent", all bars sum up to 100. To have the bars belonging to the same x-value summing up to 100, you can use multiple='fill'. Note that in the latter case, the sum is 1.0. The PercentFormatter shows the y-axis as percentages.
QUESTION
I'm using CMake in my project, as does one of my project's third-party library (included with add_subdirectory() for convenience). I have been having strange build issues, and I think I've tracked them down to the following line in the third-party library's top-level CMakeLists.txt:
ANSWER
Answered 2021-Nov-28 at 23:54For libraries that intend to be usable as a subproject (via add_subdirectory or FetchContent), I would say it is a bug to set such cache variables without a check that the project is top-level. On the other hand, a project that does not intend to be usable this way should explicitly check and issue a fatal error (or maybe an author warning) in this case. So either way, I would argue there's a bug and you should notify the maintainers.
In CMake 3.21+ the variable PROJECT_IS_TOP_LEVEL works. In earlier versions, you can write:

When using some CAM software, the CNC code is usually generated properly with spaces. But for example when moved to "Citizen Cincom L20" machine via USB or network and edited there it lose spaces and also lose semicolons while preserving new lines which does work as semicolons anyway.
But since editing of CNC program happens in 3 places: CAM Software(ESPRIT in this case), CNC machine controller and also via text editor on the computer as postprocessor in ESPRIT is garbage.I've come up with this regex
...ANSWER
Answered 2021-Nov-12 at 16:29First, go to View -> Tool Views -> Show Search and Replace. You will see
Make sure you:
- Enable
{}regex option on the right as you are using a regex - Enable "AB" option on the right that enables case sensitive matching
- Select
In Foldervalue from the dropdown on the right - Fill out the regex, replacement, Folder and the Filter fields with the appropriate values
- Click Search button.
You will see the results in a separate pane and Replace / Replace Checked buttons will become enabled.
Review the replacements and click Replace Checked:
Then you may check the updated file contents, and if you are satisifed with the results, use Save All, also by pressing CTRL+L.
QUESTION
I am new to Spring Boot and Microservices. I have created RestController and tried to check using RequestMapping test but it give us error as 404, whitelabel error page.
Below is pom.xml :
...ANSWER
Answered 2021-Nov-07 at 16:18If you are getting a 404 error page, it means that SpringBoot does not have a request mapping from this URI path to a specific controller method.
This can happen for 2 main reasons ...
- You are using the wrong request URI
- You did not create a controller bean, which is mapped to this URI
Given that I see the code for the controller bean, this means its a wrong URI.
If you did not change any of the configurations in application.properties the path you should be using to get the data should be http://localhost:8080/citizen/test. Try it out with this one ... if it does not work ... please add the output, which SpringBoot prints when starting the app to the original question. Also add a comment to this answer, so I get notified and can respond.
