QUESTION
I am trying to create a component for a popover using Bootstrap4 in Vue:
...ANSWER
Answered 2021-Jun-14 at 21:58You're losing reactivity because your content option to bootstrap.Popover is returning a string of your element's HTML, not the element itself. The popover just copies the HTML as it exists when it is opened. If you pass the element, Bootstrap will reparent the element itself into the popover, so changes to the element's children should be reflected. (Note that this could still be disrupted by a virtual DOM change that rewrote the element itself, which is why Bootstrap-Vue would still be better here.) If the popover might be reused, you'll need to reparent the element back into your component's own tree each time the popover is closed. You'll also need to make provision for the _Content element to only be hidden while it isn't reparented.
Here's how it all would look:
QUESTION
I am currently designing a web server with Typescript and have hit a dead end. The target is to have an interface or something similar that lets any other developer without a deep knowledge of the rest of the system just come in, implement their own version of the parser and have it work with the rest of the system. Additionally, I would like to have the option to add more return types without modifying the original code.
Currently, I have the shape of the data defined and I am trying to wrap my head around the parser itself. The data looks like this:
...ANSWER
Answered 2021-Jun-14 at 18:23Since the string type property inside your source arg should determine the overall return type, there is a TypeScript paradigm that can handle this mapping. It's the same one used by addEventListener and its kin in TypeScript's DOM declarations, if you want to consult a broader example.
In your case, you'll need to create a map interface between type string values and the actual types that will be returned for them. The return type of getSource will then be a lookup from that map. Unfortunately, due to some limitations in TypeScript described here, there's an inelegant cast needed when returning each of the possible types. Here's how it all might look (with simpler structures for example purposes):

I am using the system c++ call to execute the shell script the caller program is running as root but the shell sctipt which is called form the c++ code is running as different user.
How can I make sure the shell script should also run as root user like the c++ binary. I don't want to rely on using sudo command as it can ask for password.

ANSWER
Answered 2021-Jun-14 at 18:03A few bits of documentation to start:
From man 3 system's caveats section:
Do not use
system()from a privileged program (a set-user-ID or set-group-ID program, or a program with capabilities) because strange values for some environment variables might be used to subvert system integrity. For example,PATHcould be manipulated so that an arbitrary program is executed with privilege. Use theexec(3)family of functions instead, but notexeclp(3)orexecvp(3)(which also use thePATHenvironment variable to search for an executable).
system()will not, in fact, work properly from programs with set-user-ID or set-group-ID privileges on systems on which/bin/shis bash version 2: as a security measure, bash 2 drops privileges on startup. Debian uses a different shell,dash(1), which does not do this when invoked as sh.)
And from the bash manual's description of the -p command line argument (Emphasis added):
Turn on privileged mode. In this mode, the
$BASH_ENVand$ENVfiles are not processed, shell functions are not inherited from the environment, and theSHELLOPTS,BASHOPTS,CDPATHandGLOBIGNOREvariables, if they appear in the environment, are ignored. If the shell is started with the effective user (group) id not equal to the real user (group) id, and the -p option is not supplied, these actions are taken and the effective user id is set to the real user id. If the -p option is supplied at startup, the effective user id is not reset. Turning this option off causes the effective user and group ids to be set to the real user and group ids.
So even if your /bin/sh doesn't drop privileges when run, bash will when it's run in turn without explicitly telling it not to.
So one option is to scrap using system(), and do a lower-level fork()/exec() of bash -p your-script-name.
Some other approaches to allowing scripts to run at elevated privileges are mentioned in Allow suid on shell scripts. In particular the answer using setuid() to change the real UID looks like it's worth investigating.
Or configure sudo to not require a password for a particular script for a given user.

I am building an api which is supposed to send message to an IBM MQ and receive the response from another queue. But the operation has to appear synchronous to the caller of the api. I'm using Mule 3.9.2.
Seems Mule 4 has a connector called IBM MQ connector which has a publish conume operation to achieve this - https://docs.mulesoft.com/ibm-mq-connector/1.6/ibm-mq-publish-consume.

Got this error run time error 445 object doesn't support this action while trying to launch thise code . Macros works, but everytime i run it gives me this error, can i somehow get rid of it?
...ANSWER
Answered 2021-Jun-13 at 07:41You are getting the error because you are declaring an OLEobject as shape, as OLEobjectdoes not has the property of Fill.Forecolor as following:
In order to use the property of Fill.Forecolor you should draw a shape and assign the VBA code to the shape, the red one is Shape while the grey one is OLEobject
So the moment I click the shape, it will change color and also remove the pivot field as per your expectation:

For some reason, whenever the "addToData" method reaches its end, it wont return to its original caller in the main method, but instead just stops all together.

...ANSWER
Answered 2021-Jun-11 at 14:51In case of problems with valgrind, it is always recommended to try with a recent version, either the last release or the git version.
Note that it is quite easy to recompile valgrind from sources, at it has very few dependencies.
In case of specific problems with stack traces, it is always useful to compare the stack traces produced by valgrind and gdb by using valgrind + gdb + vgdb.
Put a breakpoint in gdb at relevant places, and you can then compare the gdb stacktrace produced by the gdb backtrace command and the valgrind stacktrace produced by the monitoring command:

I've been testing $MyInvocation, $MyCommand and inspecting some other variables but would like a good example of how to do the following:
- Get the name of the current script file
- Get the name of the caller script file that included the current script file
- Get the name of the original script file that ultimately resulted in #1 being executed
I have used this for original but maybe it will also be caller?
