python - Import package from unit test code -


i keep source code separate test code. so, have project organized this:

my_package/    module1.py    module2.py tests/   units/     test_a.py     test_b.py   perf_tests.py

how should test_a.py import my_package?

note: i've googled (including so) , not satisfied answers:

  • i don't want use setup.py, because want run development; testing, after all
  • i don't want use symlinks or other hacks
  • i've tried sys.path.append('../') , sys.path.append(os.path.realpath('../')). both result in importerror: no module named my_package. perhaps similar can done pythonpath - syntax?
  • i want write proper import statement can find correct files

first have include __init__.py file inside folder my_package in order allow python recognize folder valid module. can create empty __init__.py file 1 line pass, example.

then, can in test_a.py:

import os bkp = os.getcwd() os.chdir(r'..\..') import my_package os.chdir(bkp)

or use other options pythonpath or sys.path.append().

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
