Diagnostic tools for timely dataflow computations. Timely dataflows are data-parallel and scale from single threaded execution on your laptop to distributed execution across clusters of computers. Each thread of execution is called a worker. The tools in this repository have the shared goal of providing insights into timely dataflows of any scale, in order to understand the structure and resource usage of a dataflow. Each timely worker can be instructed to publish low-level event streams over a TCP socket, by setting the TIMELY_WORKER_LOG_ADDR environment variable. In order to cope with the high volume of these logging streams the diagnostic tools in this repository are themselves timely computations that we can scale out. In order to avoid confusion, we will refer to the workers of the dataflow that is being analysed as the source peers. The workers of the diagnostic computation we will refer to as inspector peers. This repository contains a library, tdiag-connect, and a command line interface to the diagnostic tools, tdiag. tdiag-connect (in /connect) is a library of utiltities that can be used by inspector peers to source event streams from source peers. tdiag (in /tdiag) is an unified command line interface to all diagnostic tools (only one is currently available, more are coming).

            As Lasse V. Karslen already commented, your code will trigger a compiler error CS0182. Next problem is the required format for AssemblyVersion - major[.minor[.build[.revision]]], there are other assembly metadata fields that can be used for strings - e.g. InformationalVersion.

            There is more than one way to add assembly meta data while building... there are probably more then these five:

            • assembly attribute
            • dotnet-cli parameter
            • msbuild parameter
            • csproj config entry
            • Build Events / Scripting is also a way to reach your goal, but is more fiddeling.
            Using assembly attribute

            The problem with the assembly attribute is that it need to be constant expression. That is not straight forward to achieve, but Gitinfo managed to serve a solution. An other disadvantage is the need to disable the compiler to generate the AssemblyInfo.cs that will break writing some values configured in csproj to the final assembly.

            You can add a dummy property that is used during serialization that handles this.

            • Add a new property with the same signature, but flag it with JsonPropertyNameAttribute to ensure it is being serialized with the correct name, and also with the JsonIgnoreAttribute so that it will not be serialized when it returns null.
            • The original property you mark with JsonIgnore, unconditionally, so that it will never be serialized itself
            • This dummy property would return null (and thus be ignored) when the actual property contains an empty list, otherwise it would return that (non-empty) list
            • Writes to the dummy property just writes to the actual property

            Looks like you have resolved the embedding part of your question and are left with just the deletion of the extracted DLLs.

            Because the DLL is inuse but your own process, unless you are able to uload the DLL successfully, I dont think you will be able to delete the DLL.

            1st Potential Option

            One thing you could try and do is schedule the deletion of the file after reboot. This SO post explains how to do that using P/Invoke and MoveFileEx.

            How to measure energy usage in Xcode 13 / iOS15?
            Asked 2022-Feb-23 at 00:43

            I'd like to confirm the battery usage of an app I am developing on iOS, specifically on Xcode 13 and iOS 15. (Note: This app previously showed no issues with battery usage on previous versions of iOS.)

            Previously, it seems that there were two ways to gather energy usage information:

            #1. On the device under Settings > Developer > Logging

            • As per Apple's documentation described in the section titled "Log Energy Usage Directly on an iOS Device".
            • However, on iOS15, I can't find any options for logging under Developer or anywhere under settings even when searching.

            #2. Profiling via Instruments using the "Energy Log" template

            • As per the same documentation from Apple described in the section "Use the Energy Diagnostics Profiling Template".
            • While it is still available in Xcode 12, this template is missing in Xcode 13. Naturally, it's also not possible to profile an iOS15 device with Xcode 12.

            Digging through the Xcode 13 release notes, I found the following:

            Instruments no longer includes the Energy template; use metrics reporting in the Xcode Organizer instead. (74161279)

            When I access the Organizer in Xcode (12 or 13), select an app and click "Energy" for all versions of the app, it shows the following:

            Apple's documentation for "Analyzing the Performance of Your Shipping App" says:

            "In some cases the pane shows “Insufficient usage data available,” because there may not be enough anonymized data reported by participating user devices. When this happens, try checking back in a few days."

            Well over a year into production and having sufficient install numbers, I have a feeling that waiting a few days might not do much.

            I would like to determine if this is a bug in my app or a bug in iOS15. How can energy usage data be gathered using Xcode 13 on iOS 15?

            ...

            Answered 2022-Feb-23 at 00:43

            After contacting Apple Developer Technical Support (DTS) regarding this issue, they provided me with the following guidance.

            Regarding "insufficient usage data available" for energy logs accessible via the Xcode organizer:

            DTS indicated that they do not publish the thresholds for active users and usage logs would be expected to be present if you have more that a few thousand active users consistently on each version of your app. If your app meets this criteria and still does not show energy logs, DTS recommended opening a bug report with them.

            Regarding how to collect energy log data for your app:

            DTS recommended using MetricKit to get daily metric payloads. Payloads are delivered to your app every 24 hours and it is then possible to consume them and send them off device.

            -Wconversion diagnostic from gcc-trunk when -fsanitize=undefined is passed
            Asked 2022-Feb-21 at 19:34

            This is about the correct diagnostics when short ints get promoted during "usual arithmetic conversions". During operation / a diagnostic could be reasonably emitted, but during /= none should be emitted.

            Behaviour for gcc-trunk and clang-trunk seems OK (neither emits diagnostic for first or second case below)... until...

            we add the entirely unrelated -fsanitize=undefined ... after which, completely bizarrely:

            gcc-trunk emits a diagnostic for both cases. It really shouldn't for the 2nd case, at least.

            Is this a bug in gcc?

            For a built-in compound assignment operator $= the expression A $= B behaves identical to an expression A = A $ B, except that A is evaluated only once. All promotions and other usual arithmetic conversions and converting back to the original type still happen.

            Therefore it shouldn't be expected that the warnings differ between short avg1 = sum / count; and tmp /= count;.

            A conversion from int to short happens in each case. So a conversion warning would be appropriate in either case.

            However, the documentation of GCC warning flags says specifically that conversions back from arithmetic on small types which are promoted is excluded from the -Wconversion flag. GCC offers the -Warith-conversion flag to include such cases nonetheless. With it all arithmetic in your examples generates a warning.

            Also note that this exception to -Wconversion has been introduced only with GCC 10. For some more context on it, the bug report from which it was introduced is here.

            It seems that Clang has always been more lenient on these cases than GCC. See for example this issue and this issue.

            For / in GCC -fsanitize=undefined seems to break the exception that -Wconversion is supposed to have. It seems to me that this is related to the undefined behavior sanitizer adding a null-value check specifically for division. Maybe, after this transformation, the warning flag logic doesn't recognize it as direct arithmetic on the smaller type anymore.

            If my understanding of the intended behavior of the warning flags is correct, I would say that this looks unintended and thus is a bug.

            Wrong result of multiplication: Undefined behavior or compiler bug?
            Asked 2022-Feb-18 at 23:52
            Background

            While debugging a problem in a numerical library, I was able to pinpoint the first place where the numbers started to become incorrect. However, the C++ code itself seemed correct. So I looked at the assembly produced by Visual Studio's C++ compiler and started suspecting a compiler bug.

            Code

            I was able to reproduce the behavior in a strongly simplified, isolated version of the code:

            Even though nobody posted an answer, from the comment section I could conclude that:

            • Nobody found any undefined behavior in the bug repro code.
            • At least some of you were able to reproduce the undesired behavior.

            So I filed a bug report against Visual Studio 2019.

            The Microsoft team confirmed the problem.

            However, unfortunately it seems like Visual Studio 2019 will not receive a bug fix because Visual Studio 2022 seemingly does not have the bug. Apparently, the most recent version not having that particular bug is good enough for Microsoft's quality standards.

            I find this disappointing because I think that the correctness of a compiler is essential and Visual Studio 2022 has just been released with new features and therefore probably contains new bugs. So there is no real "stable version" (one is cutting edge, the other one doesn't get bug fixes). But I guess we have to live with that or choose a different, more stable compiler.
