// -*- mode: cpp; mode: fold -*- // Description /*{{{*/ /* ###################################################################### Version Test - Simple program to run through a file and comare versions. Each version is compared and the result is checked against an expected result in the file. The format of the file is a b Res Where Res is -1, 1, 0. dpkg -D=1 --compare-versions a "<" b can be used to determine what Res should be. # at the start of the line is a comment and blank lines are skipped The runner will also call dpkg --compare-versions to check if APT and dpkg have (still) the same idea. ##################################################################### */ /*}}}*/ #include <config.h> #include <apt-pkg/debversion.h> #include <apt-pkg/error.h> #include <apt-pkg/fileutl.h> #include <fstream> #include <string> #include <stdlib.h> #include <sys/wait.h> #include <unistd.h> #include <gtest/gtest.h> using namespace std; static bool callDPKG(const char * const val, const char * const ref, char const * const op) { pid_t Process = ExecFork(); if (Process == 0) { const char * args[] = { BIN_DIR "/dpkg", "--compare-versions", val, op, ref, nullptr }; execv(args[0], (char**) args); exit(1); } int Ret; waitpid(Process, &Ret, 0); return WIFEXITED(Ret) == true && WEXITSTATUS(Ret) == 0; } #define EXPECT_VERSION_PART(A, compare, B) \ { \ int Res = debVS.CmpVersion(A, B); \ Res = (Res < 0) ? -1 : ( (Res > 0) ? 1 : Res); \ EXPECT_EQ(compare, Res) << "APT: A: »" << A << "« B: »" << B << "«"; \ EXPECT_PRED3(callDPKG, A, B, ((compare == 1) ?
