After upgrading to Mac OS X Catalina my parallel django tests cash.
With this in settings I get a crash, without them (when sqlite is used everything is fine)
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'xx',
'USER': 'xx',
'PASSWORD': 'xx',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
Execution command is:
python manage.py test --settings=app.settings.test --parallel
The crash report contains this:

I got this (not particularly helpful, in my eyes) crash message and was wondered what the usual suspect was for this/where I'm best to look? I'm getting this when I navigate using a NavigationLink to another View. I know from some research that this crash tends to have a different cause each time, but I wondered if the stack trace would give any clues?
Each crash companies about the same invalid attribute id: 83753. Any way I can track something down using this ID?

Any thoughts appreciated.
I am working on a program where I need to read ints from a file into an array and use the array to do work. not super complicated and shouldtm take next to no time at all.
i am still a student learning c++ and i've exhausted all my options trying to get this to function as I understand it.
The text file has 200 lines each line contains a int followed by a '\n' newline character.
When I read the file in the main function into an int it works as expected. when I pass the ifstream by reference into the function that does the exact same for loop it breaks giving me an uninitialized in as the only value.
#include<iostream> // required
#include<fstream>
#include<random>
#include<string>
using namespace std; // using standard namespace as for this entire program
void readNumbers(ifstream&, int[], int); // passing a input filestream by reference, c style array, and an integer for the array length
int totalInts(ifstream&); // this will read how many lines the file has
int main()
{
ifstream is("numbers.txt"); // this is the text file that we are reading from
int ar[200]; // the array of length 200 that everything will be read into
int temp; // temporary holding for our ints
if (!is) // error checking
cout << "somethings <expletive deleted>";
else {
for (int i = 0; i < 200; i++) // iterating through the file 200 times and inputting the int into the temp holding, this is being used to test if this method works as expected.
{
is >> temp;
cout << i << ' ' << temp << '\n'; // prints it out for troubleshooting
}
// cout << totalInts(is);
readNumbers(is, ar, 200);
}
return 0;
}
int totalInts(ifstream& file)
{
string i;
int intNum;
intNum = 0;
while (getline(file, i))
{
intNum++;
}
return intNum;
}
void readNumbers(ifstream &reading, int papi[], int rayLength) // where we really want to read the file
{
int temp; // for temp holding while we troubleshoot
if (!reading)
cout << "somethings fucked";
else
{
for (int i = 0; i < rayLength;i++) // reads the file for as many time as we have space in the array.
{
reading >> temp; // reads into temp
cout << temp; // outputs for troubleshooting
}
}
}
the program outputs below

Press any key to close this window . . .
as you can see the output for the first for loop is exactly as expected, however the function which has all the same functionality is not working and is showing an uninitialized int for temp.
this means that it is not reading from the ifstream which I passed to the function. so wrote another function that reads the file using a newly created ifstream as well as the passed ifstream and prints what is read from both streams.
totalInts(ifstream &file)
{
ifstream tester("numbers.txt");
string l,i;
int intNum;
intNum = 0;
for (int j = 0; j < 200; j++)
{
file >> l;
tester >> i;
intNum++;
cout << intNum << ' ' << i << ' ' << l << '\n';
}
file.close();
return intNum;
}
when this is used the output is as expected, so passing the ifstream as a param using reference is the issue, as when I make a new ifstream the program runs fine using that ifstream and reading the file as expected where as the passed ifstream shows no values read.

If this was up to me I would just be passing the filename through to the functions as a string param and making new ifstreams in these functions to get the thing to work, however the requirement for this is to have ad least one function that passes an ifstream through reference and utilize it. however after lots of troubleshooting and reading stackexange posts on the topic I cannot get it to function as expected.
what am I doing wrong?
any help would be appreciated.
I have two similar C++ implementations of Prim's algorithm for a minimum spanning tree, but one of them works in every situation, while the other fails in some. The difference is the method of comparison used within the priority queue.
This is the one that fails in a few situations (it uses a struct function in order to compare the cost of given arches):
#include <iostream>
#include <queue>
#include <vector>
#include <math.h>``
#include <fstream>
using namespace std;
#define NMax 200005
#define oo (1 << 30)
ifstream fin("apm.in");
ofstream fout("apm.out");
int T[NMax], n, m, C[NMax];
bool inmst[NMax];
struct comp{
bool operator()(int x, int y)
{
return C[x] > C[y];
}
};
vector <pair <int, int> > G[NMax];
priority_queue<int, vector <int>, comp> pq;
void Prim()
{
for(int i = 1; i <= n; i++)
C[i] = oo;
pq.push(1);
C[1] = 0;
while(!pq.empty())
{
int nod = pq.top();
pq.pop();
inmst[nod] = 1;
for(int i = 0; i < G[nod].size(); i++)
{
int v = G[nod][i].first;
int c = G[nod][i].second;
if(!inmst[v] && C[v] >= c)
{
C[v] = c;
pq.push(v);
T[v] = nod;
}
}
}
}
int main()
{
fin >> n >> m;
for(int i = 1; i <= m; i++)
{
int x, y, c;
fin >> x >> y >> c;
G[x].push_back(make_pair(y, c));
G[y].push_back(make_pair(x, c));
}
Prim();
int ct = 0;
for(int i = 1; i <= n; i++)
ct += C[i];
fout << ct << "\n" << n-1 << "\n";
for(int i = 1; i <= n; i++)
{
if(T[i] == 0) continue;
fout << i << " " << T[i] << "\n";
}
}
And this is the one that succeeds every time (it uses the greater within the priority queue and stores both the cost associated with a node and the node itself within the queue):
#include <iostream>
#include <queue>
#include <vector>
#include <math.h>
#include <fstream>
using namespace std;
#define NMax 200005
#define oo (1 << 30)
typedef pair<int, int> iPair;
ifstream fin("apm.in");
ofstream fout("apm.out");
int T[NMax], n, m, C[NMax];
bool inmst[NMax];
struct comp{
bool operator()(int x, int y)
{
return C[x] < C[y];
}
};
vector <pair <int, int> > G[NMax];
priority_queue< pair<int, int>, vector <pair<int, int> > , greater<pair<int, int> > > pq;
void Prim()
{
for(int i = 1; i <= n; i++)
C[i] = oo;
pq.push((make_pair(0, 1)));
C[1] = 0;
while(!pq.empty())
{
int nod = pq.top().second;
pq.pop();
inmst[nod] = 1;
for(int i = 0; i < G[nod].size(); i++)
{
int v = G[nod][i].first;
int c = G[nod][i].second;
if(!inmst[v] && C[v] > c)
{
C[v] = c;
pq.push(make_pair(C[v], v));
T[v] = nod;
}
}
}
}
int main()
{
fin >> n >> m;
for(int i = 1; i <= m; i++)
{
int x, y, c;
fin >> x >> y >> c;
G[x].push_back(make_pair(y, c));
G[y].push_back(make_pair(x, c));
}
Prim();
int ct = 0;
for(int i = 1; i <= n; i++)
ct += C[i];
fout << ct << "\n" << n-1 << "\n";
for(int i = 1; i <= n; i++)
{
if(T[i] == 0) continue;
fout << i << " " << T[i] << "\n";
}
}
Why doesn't the first one work as intended every time and how would I go about changing it while still using the struct function and the code basis I already have? I tried a similar implementation to the one I use for Dijkstra's algorithm.
The program reads the number of nodes and arches and all the given arches from a file and it's supposed to show the minimum cost of the spanning tree, the number of arches and the arches in any order.
The examples I have that fail for the 1st implementation are of pretty abnormal sizes, I don't know if they will be of any help:

Every times you pop a node u from priority_queue, you need to update C[v] with v is adjacent node with u. These v may be already in the queue, so technically, you indirectly update the value of some elements in priority_queue (since value of an element is expressed via C[]). It will break the structure of the queue and lead to incorrect answer.
In the correct version, you push 2 int to queue, and these values never change. Therefore you do not get the above problem.
Looking through the exposed sample codes, I got a suspicion about an essential difference of comparison behaviors. To prove that suspicion, I put both versions of the sample codes into WinMerge and compared them. They look really similar. So, I'm quite sure I'm on the right track:
The first version uses this for comparison:
struct comp{
bool operator()(int x, int y)
{
return C[x] > C[y];
}
};
The second version uses this instead:
std::greater<pair<int, int> >
The big difference: std::greater considers both members of std::pair in comparison but the comparison function in first sample only C[x] and C[y] (but not x and y).
According to cppreference.com
template< class T1, class T2 >
constexpr bool operator>(const pair<T1,T2>& lhs, const pair<T1,T2>& rhs);
is defined as rhs < lhs and
template< class T1, class T2 >
constexpr bool operator<(const pair<T1,T2>& lhs, const pair<T1,T2>& rhs);
does
If lhs.first<rhs.first, returns true. Otherwise, if rhs.first<lhs.first, returns false. Otherwise, if lhs.second<rhs.second, returns true. Otherwise, returns false.
So, if the first comparison shall resemble the second, the comparison functor of first sample has to be changed to e.g.:
struct comp{
bool operator()(int x, int y)
{
return x == y ? C[x] > C[y] : x > y;
}
};
That looks a bit stupid as x == y surely results in C[x] == C[y]. However, it should return the exact same results as the std::greater<std::pair<int, int> > for the second sample code.
Concerning the original problem of the OP, the first version may actually be the correct one (and there is yet another mistake or a wrong expectation about output). In this case, the comparison of second sample had to be adjusted, e.g. introducing a resp. functor for std::pair:
struct comp{
bool operator()(
const std::pair<int, int> &xCx, const std::pair<int, int> &yCy) const
{
return xCx.second > yCy.second;
}
};
As I do not know Prim's algorithm, I cannot decide which one is the actually correct solution. The OP might leave a note regarding this (and I'm would be glad to edit this in).
I installed gnuradio via macports. I have been able to install the majority of the other blocks via macports, however I was wanting to start playing with DECT and the block was not listed on macports. So I manually went to install it via the following git location:https://github.com/pavelyazev/gr-dect2
When I installed with the standard install, gnuradio did not see the block at all. After researching I found others having success by modifying the cmake call like that below.
cd gr-dect2/
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/local ..
make
sudo make install
I was then able to see the dect2 block in gnuradio, however when I went to run the example dect2.grc project I was getting the below message:
Traceback (most recent call last):
File "/Users/krotovd/gr-dect2/grc/top_block.py", line 32, in <module>
import dect2
ImportError: No module named dect2
So I found where the other modules were installed, deleted the build directory and called the original build/install commands with a modification on cmake as shown below.
cmake -DCMAKE_INSTALL_PREFIX=/opt/local/Library/Frameworks/Python.framework/Versions/2.7
Now when I open gnuradio-companion and proceed to open the detc2.grc project it crashes with the error in the title:
Loading: "/Users/krotovd/gr-dect2/grc/dect2.grc"
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6
Has anyone been able to successfully install a dect2 block for gnuradio in Mac? Seems like this has been an issue for some time now. Anyone have any ideas on how I might be able to resolve this issue?
Below is a excerpt of my error report. I am inserting the except due to the size, but I beleive what is important should be listed.

Please help me. What's wrong with my code? Or how to fix that? I ready to disable any user-controls, css, images and ect. Advise me how to make it work
I know the answer! To fix this problem, enable autoload images!
