QUESTION
In the second level of my game I made a wave system with 3 different types of zombies. This wave system spawns in three different waves. My problem is that I cannot think of a way to start the next scene because whatever I try makes it start the next scene within 1 wave. I have tried using the bools that check if the waves have ran but the problem is that I have to have one of the true or else the second and third wave spawns together. I tried putting it in the spawner for the third wave but that didn't work. I tried adding ZKLeft.Length == 0 but that didn't work. Do you know any possible ways to prevent the next scene starting early without starting a wave early? Thanks!
Sorry if the code is bad I am a student

Full questionIs it defined behavior to have an object b
placed in the coroutine state
(by e.g. having it as a parameter,
or preserving it across a suspension point),
where alignof(b) > __STDCPP_DEFAULT_NEW_ALIGNMENT__?
Example:
...ANSWER
Answered 2021-Mar-13 at 05:58From my reading, this would be undefined behavior.
dcl.fct.def.coroutine/9 covers the lookup order for determining the allocation function that will be used should the coroutine need additional storage. The lookup order is quite clear:
An implementation may need to allocate additional storage for a coroutine. This storage is known as the coroutine state and is obtained by calling a non-array allocation function ([basic.stc.dynamic.allocation]).
The allocation function's name is looked up in the scope of the promise type. If this lookup fails, the allocation function's name is looked up in the global scope. If the lookup finds an allocation function in the scope of the promise type, overload resolution is performed on a function call created by assembling an argument list. The first argument is the amount of space requested, and has type std::size_t. The lvalues
p1…pnare the succeeding arguments.If no viable function is found ([over.match.viable]), overload resolution is performed again on a function call created by passing just the amount of space required as an argument of type std::size_t.
(Emphasis mine)
This explicitly mentions that the new overload it will call must start with a std::size_t argument, and may optionally operate on a list of lvalue references p1, p2, ..., pn (if its found in the scope of the promise).
Since in your above example there is no custom operator new defined for the promise type, that means it must select ::operator new(std::size_t) as the overload.
As you already know, ::operator new is only guaranteed to be aligned to __STDCPP_DEFAULT_NEW_ALIGNMENT__ -- which is below the extended alignment required for the coroutine storage. This effectively makes any extended-aligned type in a coroutine be undefined behavior due to misalignment.
Because of how strict the wording is that it must call ::operator new(std::size_t), this should be consistent on any system that implements c++20 correctly. If an implementation chose to support extended-aligned types, it would technically be violating the standard by calling the wrong new overload (which would be an observable deviation).
Judging by the wording on the overload resolution for the allocation function, I think in a case where you require extended-alignment, you should be defining a member-based operator new for your promise that is aware of the possible alignment requirement.
QUESTION
Next to master, I have another remote repository remote/master from where I want to pull the changes then and again. This happens only about after every 20 commits or so. Consequently, it always generates these big behemoths of merge conflicts, where git wants me to resolve all 20 possible conflicts from 20 commits at once, without any further guidance.
Is there a way to be able to merge the branch, going through the commits one by one? So I can cross-check the individual conflicts with the commit messages and act accordingly. I understand that this could introduce unnecessary work when a commit undoes the changes from a previous one, but that is a very acceptable trade-off.
I know I can git cherry-pick them all, but how would I know since when to cherry-pick? Manually checking the log before every fake-"merge" process? Also, I'm not actually cherry-picking here. I want to combine two branches into one, but not all at once, as in
ANSWER
Answered 2021-Mar-05 at 13:18Is there a way to be able to merge the branch, going through the commits one by one?
Not really, that's not how git does its thing. I guess you could merge each intermediate commit one by one, then take the resulting tree and create a synthetic "merge" commit.
I know I can git cherry-pick them all, but how would I know since when to cherry-pick?
There's git merge-base, but I don't think that makes any sense. remote/master would usually be the "blessed" upstream, by cherrypicking its contents you're going to create completely unrelated commits in your branch (with similar content but not actually matching).
Most people would instead rebase their local changes onto the upstream.
This happens only about after every 20 commits or so. Consequently, it always generates these big behemoths of merge conflicts
That sounds like some seriously weird development methodology.
QUESTION
I'm using Node + Express (running locally) and connecting to a MongoDB hosted on MongoDB Atlas. My project is a behemoth that started a while back using MDN's Local Library tutorial, and it grew as I learned how to use Express, sockets, mongo, etc. So some code in it is very bad, some is less so. Now, with a mostly feature-ready product, it's having high memory usage when multiple people connect.
Using Artillery, I have 5 users/second hit my /join_session endpoint for 20 seconds. This spikes memory usage from ~35MB to ~450MB. Full disclosure, I'm terrible at reading Chrome's Node.js Devtools for memory usage. But here's what I see under system/Context:
Object Origin Distance Shallow Size Retained Size this::ConnectionPool @2726315 connection_pool.js:147 17 184 0% 351324152 79% ::Denque @3436241 index.js:6 18 56 0% 351320592 79% _list::Array @3436499 19 32 0% 351320536 79%That array has 1024 elements. Here's the statistics tab from Chrome's inspector
So it seems like mongoose's connection pool is the problem. I haven't changed my pool size, so that's the default of 5. I set up my connection in an external file that I require in App.js.
App.js
require("./mongo.js");
mongo.js
...ANSWER
Answered 2021-Mar-03 at 13:02So, as it turns out, the memory usage on the above test isn't that far off of normal. It's about 6MB per client, which isn't the worst, I just need a better server if I expect ~200 concurrent clients, and in particular I need more than the free tier of mongo cloud to serve DB requests more quickly. In production, the real memory spike I was seeing had NOTHING to do with the above. Instead, it was because I was repeatedly fetching an entire collection with ~10k records, each of which was a JSON object with props. Parsing that takes lots of memory, really fast, and will need to be the subject of a different post!

Answered 2021-Jan-05 at 10:12You are not taking into account the scope of the variables within a function.
If you want "settings" available inside the nested function you need to pass it as a parameter:
Inside your for loop, if you want settings to be available, you need to pass $settings as a parameter to the anonymous function you are introducing into spl_autoload_register:

ANSWER
Answered 2020-Feb-18 at 14:08So this boiled down to two issues.
The first problem was that the global flag for RegExes causes the JS engine to track a lastIndex property from which the next search will start when myRegex.test() is called again. Since the regex object is the same throughout the validation process, that lastIndex is updated and referenced as you type, and the form re-validates.
The second problem is that without global, the form would be considered valid as long as one line is correct. So my input could be
QUESTION
I am currently looking at diagnosing some reoccurring issues within a BizTalk environment and currently that is the issue of zombie messages. I am aware of the conditions that create these errors and whilst diagnosing the orchestration and making use of the Orchestration Debugger, I see that when a message has hit a terminate shape, it is followed by an initialisation.
The general structure of the orchestration is as follows:
The first scope is a long-running transaction and within the loop after that scope, there is a listen shape that waits for a message for 10 seconds. If a message comes in time, it enters another long-running transaction. It's like a singleton in a way? Both scopes share the same logical receive port and are correlated, only odd part is how the first scope is repeated within the loop that's inside the listen shape. (Orchestration is part of a behemoth of an application that wasn't written by myself.)
Would this initialisation after a termination (what actually causes this to happen?) cause zombies, if so is the structure of the orchestration and the transactions a cause of this? Or am I looking in the wrong place?.
Let me know if there's any extra information that can help!
...ANSWER
Answered 2020-Jan-23 at 23:50In the Orchestration debugger it will show when something start and also when it ends with slightly different icons. So what you are seeing is the end of the Orchestration.
No, that will not cause zombies. Zombies occur after it ends the logical receive location that listens for something (and it is tearing down the instance subscription) and another message arrives that matched that subscription before the Orchestration has fully ended.
QUESTION
We have inherited a large suite of code that has minimal testing. I'm looking to update and create tests.
We have a simple bean that has a private field that uses @value to inject a constant. This bean is constructed and passed around by numerous pieces of code which use the private @value. I want to set up a test suit to always inject some constant into the @value for any instantiated version of the bean.
I know how to inject a @value to a single bean, but considering how often the bean will be instantiated by spy in my test I don't want to have to inject mocks and inject @value into that mock for every case, I'd rather do this on a class level.
I'm aware that it's not good to abuse @value on private variables. We will hopefully fix this at some point, but at this point I don't want to mess with complicated number of constructors for an untestable behemoth of a class if I can avoid it. I'd like a way to test @value on a private field for now, and I'll look to moving how @value is utilized later once we have more stable/testable code base.
Can I configure this injection so it happens to all instantiated instances of the class automatically?
...ANSWER
Answered 2019-Aug-22 at 19:14Create a custom test configuration that includes your normal configuration and define the spy as a bean in there with @Primary with the custom @Value value injected in. You can include this as a class file directly in your test folder. That way, anywhere it's being autowired by the spring context, it will get the one from the test configuration instead of the one defined in your normal context.
QUESTION
What is the point of having this rectangular thingy like https://www.microsemi.com/images/soc/partners/solution/ip/Trace_small.jpg? How comes that gdbserver is able to debug over the Ethernet without any additional H/W and this TRACE32 behemoth S/W itself cannot decode/encode signals coming out of and to JTAG port? Isn't JTAG a port itself? Doesn't it send signals? Why cannot this piece of S/W interpret them? Why is this thingy needed (which BTW once works, once doesn't and in general is black magic). Is there a reason for existing of a specific device between JTAG and USB port (having in mind that TRACE32 installations has 800 MB...)
...ANSWER
Answered 2019-Jul-31 at 09:07There are probably certain aspects to consider:
- Run mode debugging vs. Stop mode debugging
- Simple signal converter vs. Smart debug probe
- Pure JTAG debugger vs. Debug & Trace tool
"Run mode debugging" means "Debug an application on a system running an operating system". That is what is also happening when you debug an application on your Windows/Linux/Mac machine. When you hit a breakpoint in your application the CPU is still running. It is only the debugged application which is stopped.
So if your embedded system is running an operating system you GDB might be able to connect via Ethernet to a gdbserver running on your target OS, which allows your to debug an application on your device.
"Stop mode debugging" means "Debugging all software on a CPU by controlling the run-state of the CPU". So if you hit a breakpoint on a CPU with stop mode debugging, you entire CPU will stop. This allows you debug bare metal applications or an operation system itself or an application in the context of the operation system or even hypervisor.
For stop mode debugging you usually need a chip with a JTAG interface (or SWD or similar) and an in-circuit debugger. Basically something which allows you to control the CPU on a very low level. In former times this was done by using an in-circuit emulator (instead of JTAG) which replaced the CPU with a special bond-out chip, which allowed also to control the chip on a very low level. To make thinks more confusing some vendors call their JTAG probes also "in-circuit emulator".
For stop mode debugging you need a probe which converts the interfaces of your PC to the low level debug interface of your chip. So basically some USB to JTAG converter. Or and Ethernet to JTAG converter.
The simplest probe I can think of is simply some device which allows you to control some GPIOs (General Purpose Input Output) pins via USB. Then all the JTAG communication protocol and higher debug protocol is totally done in software. Advantage: Very flexible. Disadvantage: Very slow.
More advanced probes know how to do JTAG and thus, only the high level debug protocol has to be handled via USB, while and the low level JTAG communication is done by the probe itself. These probes are often still quite slow, since USB is not so efficient when you need short latencies.
High end probes usually handle the debug protocol itself, which is individual for each CPU architecture or sometimes even for a single chip. So the host PC running the debug software sends only a high level command like "do a single step", while all the rest is handled by the probe itself. This boosts performance especially with complex multicore chips which required often a lot of JTAG communication until even a simple task completes.
Simple USB to JTAG converters are often already on the PCB of cheap evaluation boards. In theory you could also integrate such a converter directly in the chip itself, but this is usually not done by the chip manufacturers, since it would increase the costs of every single chip. In the professional sector high end debuggers are pretty common, because companies don't want to have their developers sitting in front of their PC just waiting for a slow debugger to finish an application download.
In general I assume that the faster, more flexible and more feature-rich a debugger is, the bigger and more expensive it gets. So it depends a lot on your needs.
Pure JTAG debugger vs. Debug & Trace toolAll JTAG debuggers allow you to stop and restart your CPU, set breakpoints and read and write memory and CPU registers. That is the stop more debugging I've mentioned above.
Some debug probes allow you also to record the code execution and data accesses by the CPU while the CPU is running and without stopping it. This is called a Real Time Trace. For such a trace recording you need both a debug probe and a chip which supports this.
E.g. on ARM Cortex chips this feature is called the ETM, which is not available with Cortex-M0/M0+ chips but usually available with Cortex-A/R chips and Cortex-M3 (and bigger) chips when the chip has 100 pins and more.
Tools which support trace are usually bigger and more expensive than debug probes without trace support.
Things which have an influence on the price of a debugger with trace recorder:
- Size of internal memory to save the trace data
- Supported maximum speed on one target trace pin (for parallel trace).
- Number of supported trace pins (for parallel trace) (e.g. single pin SWO trace is usually much cheaper than ETM trace).
- Support of high speed serial trace ports/maximum speed per lane/number of supported lanes.
- Upload speed to the host PC (Does the probe have a USB 3 and/or Gigabit Ehternet inteface or just USB 2?)
The device from Lauterbach, which you are referring to, supports the tracing of Cortex-M chips with a total of 1600 MBit/s on the trace port. The official product page is here https://www.lauterbach.com/microtrace.html
You wrote
which BTW once works, once doesn't and in general is black magic
If your tool is not working, I suggest to request support from your tool vendor. For Lauterbach visit https://www.lauterbach.com/tsupport.html
JTAG debugging itself is really not black magic: The JTAG protocol itself is an IEEE standard and the debug protocol (on the next level) is often described in the chip manufacturers manuals accessible to the public. However it is of course a lot of engineering.
