Answered 2021-Jun-16 at 00:25

You should use cache.asMap().remove(key) as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.

The Cache interface is opinionated for how one should commonly use a cache, while the asMap() view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.

QUESTION

Using std::atomic with futex system call

Asked 2021-Jun-15 at 20:48

In C++20, we got the capability to sleep on atomic variables, waiting for their value to change. We do so by using the std::atomic::wait method.

Unfortunately, while wait has been standardized, wait_for and wait_until are not. Meaning that we cannot sleep on an atomic variable with a timeout.

Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.

Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic to WaitOnAddress on Windows and it will (kinda) work with no UB, as the function gets void* as a parameter, and it's valid to cast std::atomic to void*

On Linux, it is unclear whether it's ok to mix std::atomic with futex. futex gets either a uint32_t* or a int32_t* (depending which manual you read), and casting std::atomic to u/int* is UB. On the other hand, the manual says

The uaddr argument points to the futex word. On all platforms, futexes are four-byte integers that must be aligned on a four- byte boundary. The operation to perform on the futex is specified in the futex_op argument; val is a value whose meaning and purpose depends on futex_op.

Hinting that alignas(4) std::atomic should work, and it doesn't matter which integer type is it is as long as the type has the size of 4 bytes and the alignment of 4.

Also, I have seen many places where this trick of combining atomics and futexes is implemented, including boost and TBB.

So what is the best way to sleep on an atomic variable with a timeout in a non UB way? Do we have to implement our own atomic class with OS primitives to achieve it correctly?

(Solutions like mixing atomics and condition variables exist, but sub-optimal)

...

ANSWER

Answered 2021-Jun-15 at 20:48

You shouldn't necessarily have to implement a full custom atomic API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic and pass it to the system.

Since std::atomic does not offer some equivalent of native_handle like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.

For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T type -- at least for integral values ^[1]. This is an assurance that will make it possible to extract out this value.

... and casting std::atomic to u/int* is UB

This isn't actually the case.

std::atomic is guaranteed by the standard to be Standard-Layout Type. One helpful but often esoteric properties of standard layout types is that it is safe to reinterpret_cast a T to a value or reference of the first sub-object (e.g. the first member of the std::atomic).

As long as we can guarantee that the std::atomic contains only the u/int as a member (or at least, as its first member), then it's completely safe to extract out the type in this manner:

QUESTION

How to pass additional values to MVC client from Identity Server 4 after authenticating user

Asked 2021-Jun-15 at 19:18

How can we pass additional data to Client application from Identity Server 4 in response after successful authentication?

We are using Identity Server 4 as an Auth server for our application to have user authentication and SSO feature. User information is stored and is getting authenticated by an external service. IDS calls the external service for user authentication. On successful authentication, the service returns the response back to IDS with 2 parameters:

Authorization code
Additional information (a collection of attributes) for the user.

IDS further generates Id token and returns response back to MVC client with standard user claims. I want to pass the additional user information(attributes) to client application to display it on page. We tried adding the attributes as claims collection through context.IssuedClaims option but still I am not getting those attributes added and accessible to User.Claims collection in MVC client app.

Can anyone suggest an alternative way by which we can pass those custom attributes to client app. either through claims or any other mode (httpcontext.Items collection etc)

...

ANSWER

Answered 2021-Jun-15 at 19:18

Only some user claims provided by the IDS will be passed into the User.claims collection. You need to explicitly map those additional claims in the client application, using code like:

Starting with 6.4 RC5 (which is the version you run as of this writing and should provide this in your original post):

The collection of thymeleaf user interface template pages are no longer found in the context root of the web application resources. Instead, they are organized and grouped into logical folders for each feature category. For example, the pages that deal with login or logout functionality can now be found inside login or logout directories. The page names themselves remain unchecked. You should always cross-check the template locations with the CAS WAR Overlay and use the tooling provided by the build to locate or fetch the templates from the CAS web application context.

QUESTION

Accessing Aurora Postgres Materialized Views from Glue data catalog for Glue Jobs

Asked 2021-Jun-15 at 13:51

I have an Aurora Serverless instance which has data loaded across 3 tables (mixture of standard and jsonb data types). We currently use traditional views where some of the deeply nested elements are surfaced along with other columns for aggregations and such.

We have two materialized views that we'd like to send to Redshift. Both the Aurora Postgres and Redshift are in Glue Catalog and while I can see Postgres views as a selectable table, the crawler does not pick up the materialized views.

Currently exploring two options to get the data to redshift.

Output to parquet and use copy to load
Point the Materialized view to jdbc sink specifying redshift.

Wanted recommendations on what might be most efficient approach if anyone has done a similar use case.

Questions:

In option 1, would I be able to handle incremental loads?
Is bookmarking supported for JDBC (Aurora Postgres) to JDBC (Redshift) transactions even if through Glue?
Is there a better way (other than the options I am considering) to move the data from Aurora Postgres Serverless (10.14) to Redshift.

Thanks in advance for any guidance provided.

...

Answered 2021-Jun-15 at 13:51

Went with option 2. The Redshift Copy/Load process writes csv with manifest to S3 in any case so duplicating that is pointless.

Regarding the Questions:

N/A
Job Bookmarking does work. There is some gotchas though - ensure Connections both to RDS and Redshift are present in Glue Pyspark job, IAM self ref rules are in place and to identify a row that is unique [I chose the primary key of underlying table as an additional column in my materialized view] to use as the bookmark.
Using the primary key of core table may buy efficiencies in pruning materialized views during maintenance cycles. Just retrieve latest bookmark from cli using aws glue get-job-bookmark --job-name yourjobname and then just that in the where clause of the mv as where id >= idinbookmark

conn = glueContext.extract_jdbc_conf("yourGlueCatalogdBConnection") connection_options_source = { "url": conn['url'] + "/yourdB", "dbtable": "table in dB", "user": conn['user'], "password": conn['password'], "jobBookmarkKeys":["unique identifier from source table"], "jobBookmarkKeysSortOrder":"asc"}

datasource0 = glueContext.create_dynamic_frame.from_options(connection_type="postgresql", connection_options=connection_options_source, transformation_ctx="datasource0")

That's all, folks

ANSWER

Answered 2021-Jun-15 at 09:52

Based on the storage class spec, I think the problem is the volumeBindingMode being set as WaitForFirstConsumer which means the PV will remain unbound until there is a Pod to consume it.

You can change it Immediate to allow the PV to be bound immediately without requiring to create a Pod.

You can read about the different volume binding modes in detail in the docs.
