            QUESTION

            Does opening a file in a child process create a separate entry in the system open file table in the kernel?
            Asked 2021-Jun-15 at 23:17

            I understand that after calling fork() the child process inherits the per-process file descriptor table of its parent (pointing to the same system-wide open file tables). Hence, when opening a file in a parent process and then calling fork(), both the child and parent can write to that file without overwriting one another's output (due to a shared offset in the open-file table entry).

            However, suppose that, we call open() on some file after a fork (in both the parent and the child). Will this create a separate entries in the system-wide open file table, with a separate set of offsets and read-write permission flags for the child (despite the fact that it's technically the same file)? I've tried looking this up and I don't seem to be able to find a clear answer.

            I'm asking this mainly since I was playing around with writing to files, and it seems like only one the outputs of the parent and child ends up in the file in the aforementioned situation. This seemed to imply that there are separate entries in the open file table for the two separate open calls, and hence separate offsets, so the slower process overwrites the output of the other process.

            To illustrate this, consider the following code:

            ANSWER

            Answered 2021-May-03 at 20:22

            There is a difference between a file and a file descriptor (FD).

            All processes share the same files. They don't necessarily have access to the same files, and a file is not its name, either; two different processes which open the same name might not actually open the same file, for example if the first file were renamed or unlinked and a new file were associated with the name. But if they do open the same file, it's necessarily shared, and changes will be mutually visible.

            But a file descriptor is not a file. It refers to a file (not a filename, see above), but it also contains other information, including a file position used for and updated by calls to read and write. (You can use "positioned" read and write, pread and pwrite, if you don't want to use the position in the FD.) File descriptors are shared between parent and child processes, and so the file position in the FD is also shared.

            Another thing stored in the file descriptor (in the kernel, where user processes can't get at it) is the list of permitted actions (on Unix, read, write, and/or execute, and possibly others). Permissions are stored in the file directory, not in the file itself, and the requested permissions are copied into the file descriptor when the file is opened (if the permissions are available.) It's possible for a child process to have a different user or group than the parent, particularly if the parent is started with augmented permissions but drops them before spawning the child. A file descriptor for a file opened in this manner still has the same permissions uf it is shared with a child, even if the child would itself be able to open the file.

            Application Insights starttrackevent stopstrackevent across pages in a single session
            Asked 2021-Jun-15 at 22:35

            I am having trouble tracking down documentation on this, so hoping someone knows as I am not able to get application insights to capture telemetry on starttrackevent and stopstrackevent across pages. This is an asp.net mvc application, so SPA is not in play here.

            I am worried I may be doing something incorrectly, however the likely case is it doesn't support it.

            Flow:

            • user hits site for the first time
            • user does action that triggers startTrackEvent("eventName");
            • user navigates to a new page
            • user does action that triggers stopTrackEvent("eventName");

            -- from the appInsights readme https://github.com/microsoft/ApplicationInsights-JS/blob/master/README.md

            appInsights.startTrackEvent("event");

            appInsights.stopTrackEvent("event", null, {customProp1: "some value"});

            Within the function you need to find each element in the passed array. However the type of the array is unknown. You only know the size of each element of the array and the starting address of the array that is passed through the parameter base0. of the type const void *..

            To access an element of the array you need to use the pointer arithmetic. But the type void is incomplete type. Its size is unknown/ So you may not use the pointer of the type (const) void *` in expressions with the pointer arithmetic.

            let returns the result of last expression inside it, in this case the value of builder.create(), a non-nullable AlertDialog.

            Since you use ?.let, if activity is null, let won't be called, and you will effectively have null ?: throw....

            builder.create() never returns null, so this throw expression is only reached when activity is null, so the error message doesn't make sense.

            Qt - trying to align two GroupBoxes in a layout
            Asked 2021-Jun-15 at 17:18

            A part of my form contains QGroupBox (Status Box) with 4 child QGroupBoxes arranged in a grid layout (2x2). Two bottom QGroupBoxes (Widget 1 Box and Widget 2 Box) contain widgets of fixed size (with set minimumSize and maximumSize) so they're non-resizable at all in both directions. Because of that rigid size constraints top row of QGroupBoxes (Summary Box and Helper Box) can only be resized in vertical direction.

            And here comes the troublesome part. Top-left QGroupBox (Summary Box) have grid layout 5x3 while top-right (Helper Box) have vertical layout with 6 rows. If I have naive widget placement as shown on picture 1 Qt is enlarging vertical size of both labels in top row to make height of both QGroupBoxes equal (see red arrows on picture 1).

            This is definitely that I don't want so I've added vertical spacer to the bottom of Summary Box and from the first glance it worked (picture 2). But only from the first glance... What you see is the minimum height of my whole form and the bottom side of spacer and last QCheckBox in the Helper Box seems to be aligned.

            If I'm expanding my form vertically this spacer grows a bit and that causes the increase of height of both top QGroupBoxes. As a result spacing between QCheckBoxes increases too and we can also see that top and bottom spacing are unequal for the top-right box (see red arrows on picture 3).

            I've tried to play with sizeType for my vertical spacer. If I set it to Minimum or MinimumExpanding then the spacer doesn't grow on resize (and doesn't shrink, too) but it appears to be expanded to the size as on picture 3 (corrupting spacings between QCheckBoxes too). If I set it to Maximum, Preferred or Expanding then I observe the same behavior as described above for picture 3.

            What is the proper way to achieve alignment for two QGroupBoxes in a row of grid without affecting spacing between elements (e. g. in that case make vertical spacer to fit only single row of grid layout and never expand/shrink)?

            ...

            ANSWER

            Answered 2021-Jun-15 at 17:18

            Items will be aligned if both QGroupBoxes have same count of children and each row have at least one child with Expanding vertical policy. Instead of spacer use QWidget

            I removed unrelated widgets and reduces number of rows to 4 for demonstration purposes (less xml).

            The Problem

            Basically, the problem at hand is that rodio::Decoder::new consumes the value which it reads from (well, actually it is already consumed by BufReader::new). So, if you have a loop or a closure that can be called multiple times, you have to come up with a fresh value each time. This what File::open does in your first code snipped.

            In your second code snipped, you only create a File once, and then try to consume it multiple times, which Rust's ownership concept prevents you from doing.

            Also notice, that using reference is sadly not really an option with rodio since the decoders must be 'static (see for instance the Sink::append trait bound on S).

            The Solution

            If you think your file system is a bit slow, and you want to optimize this, then you might actually want to read the entire file up-front (which File::open doesn't do). Doing this should also provide you with a buffer (e.g. a Vec) that you can clone, and thus allows to repeatedly create fresh values that can be consumed by the Decoder. Here is an example doing this:

            I'm not familiar with Discord bots but I don't think your endHandler will ever run the else if part the way it is because your code is always creating a new dispatcher when it plays the next song, but never sets up a finish handler for it.
