QUESTION
I have a C# project targeting .NET Core 3.1 where I resolved all compiler warnings and set TreatWarningsAsErrors
to true
. It builds just fine both from Visual Studio and the command line.
However, the build on the build server fails and reports one of the warnings as an error: CS8625. The only difference I can spot is the version of the MS build engine:
- 16.8.3 locally
- 16.7.2 on a build server
I failed to find the explicit information in the release notes, but it's my gut feeling that the changes between the mentioned versions are the root cause of such behavior.
Obviously, I can disable the mentioned warning in the .editorconfig
file, and it won't be reported both locally and on a build server, but I would prefer it to behave the other way around.
Is it possible to set things up the way the warnings are reported consistently disregarding the build engine version?
...ANSWER
Answered 2021-Jun-11 at 05:12It could also be a version of Roslyn, not related to MSBuild. Both MSBuild and Roslyn evolve rapidly, so it's hard to expect that their behavior will be identical across all versions. You can temporarily fix or ignore the warning so that your CI passes until it gets updated to a newer MSBuild.
See here for an example: https://github.com/dotnet/roslyn/issues/39906
QUESTION
I'm having a theoretical (non-deterministic, hard to test, never happened in practice) hardware issue reported by hardware vendor where double-word write to certain memory ranges may corrupt any future bus transfers.
While I don't have any double-word writes explicitly in C code, I'm worried the compiler is allowed (in current or future implementations) to coalesce multiple adjacent word assignments into a single double-word assignment.
The compiler is not allowed to reorder assignments of volatiles, but it is unclear (to me) whether coalescing counts as reordering. My gut says it is, but I've been corrected by language lawyers before!
Example:
...ANSWER
Answered 2021-May-20 at 08:01No, the compiler is absolutely not allowed to optimize those two writes into a single double word write. It's kind of hard to quote the standard since the part regarding optimizations and side effects is so fuzzily written. The relevant parts are found in C17 5.1.2.3:
The semantic descriptions in this International Standard describe the behavior of an abstract machine in which issues of optimization are irrelevant.
Accessing a volatile object, modifying an object, modifying a file, or calling a function that does any of those operations are all side effects, which are changes in the state of the execution environment.
In the abstract machine, all expressions are evaluated as specified by the semantics. An actual implementation need not evaluate part of an expression if it can deduce that its value is not used and that no needed side effects are produced (including any caused by calling a function or accessing a volatile object).
Accesses to volatile objects are evaluated strictly according to the rules of the abstract machine.
When you access part of a struct, that in itself is a side-effect, which may have consequences that the compiler can't determine. Suppose for example that your struct is a hardware register map and those registers need to be written in a certain order. Like for example some microcontroller documentation could be along the lines of: "reg0 enables the hardware peripheral and must be written to before you can configure the details in reg1".
A compiler that would merge the volatile
object writes into a single one would be non-conforming and plain broken.

QUESTION
Because I need to remove duplicate messages and delay processing some messages which are "too new" (as determined by the most recent copy of a message), I want to handle the entire contents of Service Bus Queue all at once.
I'm not sure how many messages I can expect, but I feel strongly optimistic that it shouldn't normally be in the hundreds, never mind that thousands which I thought could be the limit for ReceiveAsync (int maxMessageCount, TimeSpan operationTimeout)
. However, it turns out that no matter how high that value is, I'm only able to read about 30 to 50 messages in a single invocation of
ANSWER
Answered 2021-May-03 at 20:04A few foundational assumptions:
- Number of the requested message is not guaranteed to be the number of delivered messages.
- Messages received in
PeekLock
mode will have their lock expired at some point and will be delivered.
If your objective to drain all the messages, you should either complete the messages you've received or receive in ReceiveAndDelete
mode. That way you won't get the same messages again. If you trying to peek at the messages in the queue, then your LockDuration
would need to be long enough to ensure all messages have peeked.
I need to remove duplicate messages and delay processing some messages which are "too new" (as determined by the most recent copy of a message), I want to handle the entire contents of Service Bus Queue all at once.
The bigger issue seems to be the attempt to handle messages in the queue like records in a database. Duplicate detection is already a feature of Azure Service Bus. Deferring messages as well. But it would require a different approach than batch processing.
