80% of Peril is available today in GitHub Actions. Key things which are not:. Is this enough to warrant self-hosting? Maybe, but it's pushing it a bit if you aren't comfortable hosting a JS project. Danger got extended with a lot of Peril's features in order to better support GitHub Actions during the alpha. Given that I, Orta, can't install Peril on the Microsoft GitHub org, and GitHub Actions has most of Peril's features - it's unlikely that I'll be building much more into the core. I'll keep it ticking though, it's not much work.

QUESTION
I'm a bit confused about how to manage state withing a StatefulWidget. The following is a simplified example of a problem I am running into:
I have a StatefulWidget designed to display a list of things. It is constructed with a list that was retrieved from an API. The widget also allows the user to add new items to the list, hitting the API to do so. The API in turn returns the entire list after adding the item.
The challenge I'm running into is that the widget is constructed with an api.List object. Dart requires StatefulWdigets to be immutable (and therefore all of the fields final), and therefore the list cannot be replaced with a new list returned by the API when a user adds an item to it. That part makes sense to me: mutable state should live in the state object, not the widget. So that would suggest that the state object should keep track of the list. That leads to two different problems:
The state object is created in the
createStatemethod of theStatefulWidget. If we wanted to pass in the list to the constructor of the state object, the list would need to be stored as a final field on theStatefulWidgetas well. Now both the widget and it's state object would have a reference to the list. As the user adds items to the list, and the state object replaces its list with the new copy returned from the API, the two would be out of sync.Even if you did this, the linter will complain about including logic in the
createStatemethod: https://dart-lang.github.io/linter/lints/no_logic_in_create_state.html. It appears that they strongly suggest state objects should always have 0-argument constructors and you should never passing anything from theStatefulWidgetto theStateobject. They suggest always accessing such data via thewidgetof theStateobject. But that leads you back to the problem of theStatefulWidgetbeing immutable: you won't be able to replace the list if it is a final field on theStatefulWidgetobject.
Here, we avoid the linting issue of having logic in the createState method. But you cannot replace widget.list with newList since it is final.
ANSWER
Answered 2022-Mar-29 at 16:01The second snippet is closer the solution. Essentially, nothing makes it necessary for the list in ListWidget and the list in _ListWidgetState to be in "sync". In fact, the best way to look at it is that the list in the ListWidget is the initial data and the list in _ListWidgetState is the updated data, if there is any change made by the user. You can rely upon the data in the second list as you maintain it when the user makes changes.

QUESTION
I am currently writing a class for a polygon that will be drawn onto the screen. My problem however, is that I am unable to figure out how to create an array of structs from an array of arrays (which hold integers, for x and y of each vertex). I am passing this array through the constructor. I assume my error is to do with trying to pass a pointer as an integer, although, after perilous research I can not seem to get my head around how to solve my error. I come from a background of dynamically typed languages (Js and Python mainly) and this is my first large project in a statically typed language. Any help is greatly appreciated.

QUESTION
git and a workflow where I have many loose changes that are not intended for check-in. Is there a good git way to manage those not-for-check-in modified files?
In my project, we have about 700,000 source files. I'd call it a larger project.
When I am working on fixing a bug or implementing a feature, I will quite frequently end up with many files that I have made ancillary edits. Such as debugging instrumentation, or alternative implementation, or an expensive check for a never-happen situation that once appears to have happened in the wild and I want to catch it if it ever happens on my machine, or clang-format because the original had goofy formatting.
To commit my good changes, I'll branch, I carefully add the relevant files and commit those. (Followed by a push of my changes. Make a PR. Get code review approval. Jenkins builds on all the dozen different target platforms, and runs the test suite. Then I merge my branch into main.)
Probably a fairly typical workflow... except for that I have many (1000+) not-for-check-in files that I want to keep modified in my worktree, but not merge those into main. That latter part is probably atypical.
With Perforce, I would add my not-for-check-in files into a not-for-check-in changelist and park them there. They'd be out of the way, and I could not accidentally pull one of those "tainted" files without taking steps to move it out of the not-for-check-in changelist.
So far, my git tactic of being super-duper careful has worked, but seems fraught with peril. I maintain a stash.txt file that has a list of my not-for-check-in files, and frequently stash them to temporarily get them out of the way, do my git things (making branches, fetch, merge, push, whatever), and stash pop them back in my worktree. Seems janky, manual, and error prone; high cognitive load. Has to be a better way.
(I have not run into the scenario when I have a single file that has both good changes and not-for-check-in changes. If/when I do, I am aware of how to add-and-commit hunks of changes.)
I have tried the tactic of making a branch, add-and-commit both my good changes and not-for-check-in changes. Then cherry pick the good changes for what should go into main. That scales poorly with the 1000s of not-for-check-in files that need to be sifted through.
Any advice or guidance is appreciated.
...ANSWER
Answered 2021-Nov-11 at 15:36Using git worktree, I would work with two separate working tree (from the same cloned repository: no need to clone twice)
- one for the work in progress, with many files not to be added
- one for reporting the work which needs to be added: no stash to maintain in this one.
Does Git support multiple concurrent index (or staging), which would be the analog to Perforce changelist?
Not really: it would be easier to make multiple commits:
- one your PR
- one for the rest
And push only the first commit (for PR).
From the discussion:
"How can I make Git "forget" about a file that was tracked, but is now in .gitignore?" uses
git update-index --skip-worktree, which I don't find very practical, or easier thangit stash.git rebase -ifollwoed bygit push :should be enough
QUESTION
At great peril, I am trying to combine the use of a native query, @SqlResultSetMapper + non-entity POJO (MyDto), and a repository method that takes a Pageable as a param and returns Page. After overcoming a number of hurdles, it's almost working:
- My entity class is called
Order, as is the database table - My DTO class, to which I am mapping the results of the query, is
MyDto - My repository is defined as
public interface MyRepository extends JpaRepository
In my repository, if I use:
List findResults(Pageable page) I get a list of 1 page of results; everything works fine.
However, if I use:
Page findResults(Pageable page), this happens:

QUESTION
ANSWER
Answered 2021-Aug-07 at 11:23In an SQL database system, NULL is not equal to NULL (usually NULL = NULL returns NULL), therefore if the fields are nullable, it means that the other field can be repeated an arbitrary number of times.
What we can do is implement three constraints: uniques on the two fields, uniqness on one field if the other is NULL and vice-versa, so then the constraints look like:

QUESTION
I'm about 1 month into learning Go and I've read quite a bit about range and slices and all of the perils that come along with this complex topic. Unfortunately, I'm sort of stumped on this particular issue. I'm hoping this example isn't too contrived, but I tried to come up with a minimal example.
The issue is that the first time I add bird via addNoise, the bird gets added, but it doesn't make a sound. If I call addNoise a second time with bird, then it seems to work OK. However, I'm still missing the first sound I tried to add.
I think the problem lies solely in how I'm returning the animal in getOrCreateAnimal, but I don't see what I'm doing wrong. I suspect that the return address of the newly created animal is different than the one that is stored in the slice.
I probably overlooked an important fact about slices and I truly appreciate somebody helping me understand what I'm missing.
I'm running this example on Go 1.15.
...ANSWER
Answered 2021-Feb-18 at 07:06The Animal instance you're returning and the one you're adding to your slice aren't the same. Try returning a pointer to the instance in the slice and you should be fine
