c++ - Why does google test ASSERT_FALSE not work in methods but EXPECT_FALSE does -


both assert_true , assert_false not compile in librarytest class error.

error c2664: 'std::basic_string<_elem,_traits,_alloc>::basic_string(const std::basic_string<_elem,_traits,_alloc> &)' : cannot convert parameter 1 'void' 'const std::basic_string<_elem,_traits,_alloc> &'

it works since in test_f use. expect_false compiles fine in both librarytest class , test_f methods.

how can use assert in method used test_f?

class librarytest : public ::testing::test { public:     string create_library(string libname)     {         string libpath = setup_library_file(libname);          librarybrowser::reload_models();          assert_false(library_exists_at_path(libpath));         new_library(libname, libpath);         assert_true(library_exists_at_path(libpath));         expect_false(library_exists_at_path(libpath));         return libpath;     } };  test_f(librarytest, libraries_changed) {     string libname = "1xevtestlibrary";     string libpath = create_library(libname); }

functions using of gtest assertions need return void. in case, change function thus:

void create_library(const string &libname, string &libpath) {   libpath = ...   assert_false(...) }

and use this:

test_f(librarytest, libraries_changed) {   string libname = "foo";   string libpath;   create_library(libname, libpath); }

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), ...
