QUESTION
I just saw that C++23 plans to deprecate both std::aligned_storage and std::aligned_storage_t as well as std::aligned_union and std::aligned_union_t.
Placement new'd objects in aligned storage are not particularly constexpr friendly as far as I understand, but that doesn't appear to be a good reason to throw out the type completely. This leads me to assume that there is some other fundamental problem with using std::aligned_storage and friends that I am not aware of. What would that be?
And is there a proposed alternative to these types?
...ANSWER
Answered 2022-Apr-11 at 14:18Here are three excerpts from P1413R3:
Background
aligned_*are harmful to codebases and should not be used. At a high level:
- Using
aligned_*invokes undefined behavior (The types cannot provide storage.)- The guarantees are incorrect (The standard only requires that the type be at least as large as requested but does not put an upper bound on the size.)
- The API is wrong for a plethora of reasons (See "On the API".)
- Because the API is wrong, almost all usage involves the same repeated pre-work (See "Existing usage".)
On the API
std::aligned_*suffer from many poor API design decisions. Some of these are shared, and some are specific to each. As for what is shared, there are three main problems [only one is included here for brevity]:
- Using
reinterpret_castis required to access the valueThere is no
.data()or even.dataonstd::aligned_*instances. Instead, the API requires you to take the address of the object, callreinterpret_cast(...)with it, and then finally indirect the resulting pointer giving you aT&. Not only does this mean that it cannot be used inconstexpr, but at runtime it's much easier to accidentally invoke undefined behavior.reinterpret_castbeing a requirement for use of an API is unacceptable.
Suggested replacementThe easiest replacement for
aligned_*is actually not a library feature. Instead, users should use a properly-aligned array ofstd::byte, potentially with a call tostd::max(std::initializer_list). These can be found in theandheaders, respectively (with examples at the end of this section). Unfortunately, this replacement is not ideal. To access the value ofaligned_*, users must callreinterpret_caston the address to read the bytes asTinstances. Using a byte array as a replacement does not avoid this problem. That said, it's important to recognize that continuing to usereinterpret_castwhere it already exists is not nearly as bad as newly introducing it where it was previously not present. ...
The above section from the accepted proposal to retire aligned_* is then followed with a number of examples, like these two replacement suggestions:

I recently upgraded all of my dependencies in package.json to the latest. I went from Angular 12.2.0 to 13.0.1 and github is now rejecting my push with the following file size error. Is there some setting I need to define in angular.json build profile that will help minimize these cache file sizes?

Answered 2021-Nov-24 at 16:53Make sure your .gitignore is in the parent folder of .angular.
In that .gitignore file, a simple .angular/cache/ should be enough to ignore that subfolder content.

I have added android:exported="true" to my only activity in manifest but still getting below error after updating compile sdk and target sdk version to 31.I also tried rebuilding the project , invalidating cache and restart but that didn't helped
Error- Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
ANSWER
Answered 2021-Oct-05 at 10:38After the build has failed go to AndroidManifest.xml and in the bottom click merged manifest see which activities which have intent-filter but don't have exported=true attribute. Or you can just get the activities which are giving error.
Add these activities to your App manifest with android:exported="true" and app tools:node="merge" this will add exported attribute to the activities giving error.

QUESTION
To the internal content of an optional, doesn't the optional require placement new in order to reconstruct the internal in place storage or union? Is there some new feature like placement new in C++ 20 that allows for constexpr assignment of std::optional?
...ANSWER
Answered 2021-Dec-26 at 03:03To the internal content of an optional, doesn't the optional require placement new in order to reconstruct the internal in place storage or union?
For assignment, yes it does.
But while we still cannot do actual placement new during constexpr time, we did get a workaround for its absence: std::construct_at (from P0784). This is a very limited form of placement new, but it's enough to get optional assignment working.
The other change was that we also needed to be able to actually change the active member of a union - since it wouldn't matter if we could construct the new object if we couldn't actually switch. That also happened in C++20 (P1330).
Put those together, and you get a functional implementation of optional assignment: P2231. An abbreviated implementation would look like this:

I am using the Google Tag Manager with a single tag referencing a default Google Analytics script. My solution is based on the information from these resources:

index.html: define gtag() and set denied as a default for all storages
ANSWER
Answered 2021-Dec-08 at 10:11From your screenshot, gtm.js is executed before the update of the consent mode so the pageview continues to be sent to Google Analytics as denied.
The update must take place before gtm.js
QUESTION
It appears that by default, Rails Active Storage nests your file uploads by means of the associated active_storage_blob key.
The rules appear to be as follows for the default behavior. Within the /storage/ directory:
- take the first two characters of the
keyand make a directory- within that directory, take the next two characters of the
keyand make another directory- store the file there, and the file name is the entire
key
- store the file there, and the file name is the entire
- within that directory, take the next two characters of the
For example: where the key of a particular file's associated active_storage_blob is: 2HadGpe3G4r5ygdgdfh5534346, It would look like the following:
I do not want this nesting behavior. I want to store the files flat within the storage directory. So I simply want it to look like this:
How can I do that? A google search and a read through of the Active Storage Rails Guides didn't reveal a solution.
