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 ##################################################################### */ /*}}}*/ #include <system.h> #include <apt-pkg/error.h> #include <apt-pkg/version.h> #include <iostream.h> #include <fstream.h> static int verrevcmp(const char *val, const char *ref) { int vc, rc; long vl, rl; const char *vp, *rp; if (!val) val = ""; if (!ref) ref = ""; for (;;) { vp = val; while (*vp && !isdigit(*vp)) vp++; rp = ref; while (*rp && !isdigit(*rp)) rp++; for (;;) { vc= val == vp ? 0 : *val++; rc= ref == rp ? 0 : *ref++; if (!rc && !vc) break; if (vc && !isalpha(vc)) vc += 256; /* assumes ASCII character set */ if (rc && !isalpha(rc)) rc += 256; if (vc != rc) return vc - rc; } val = vp; ref = rp; vl = 0; if (isdigit(*vp)) vl = strtol(val,(char**)&val,10); rl = 0; if (isdigit(*rp)) rl = strtol(ref,(char**)&ref,10); if (vl != rl) return vl - rl; if (!*val && !*ref) return 0; if (!*val) return -1; if (!*ref) return +1; } } #if 0 static int verrevcmp(const char *val, const char *ref) { int vc, rc; long vl, rl; const char *vp, *rp; if (!val) val= ""; if (!ref) ref= ""; for (;;) { vp= val; while (*vp && !isdigit(*vp) && *vp != '~') vp++; rp= ref; while (*rp && !isdigit(*rp) && *rp != '~') rp++; for (;;) { vc= val == vp ? 0 : *val++; rc= ref == rp ? 0 : *ref++; if (!rc && !vc) break; if (vc && !isalpha(vc)) vc += 256; /* assumes ASCII character set */ if (rc && !isalpha(rc)) rc += 256; if (vc != rc) return vc - rc; } val= vp; ref= rp; if (*vp == '~') val++; if (*rp == '~') ref++; vl=0; if (isdigit(*val)) vl= strtol(val,(char**)&val,10); rl=0; if (isdigit(*ref)) rl= strtol(ref,(char**)&ref,10); if (vl == 0 && rl == 0) { if (*vp == '~' && *rp != '~') return -1; if (*vp != '~' && *rp == '~') return +1; } if (*vp == '~') vl *= -1; if (*rp == '~') rl *= -1; if (vl != rl) return vl - rl; if (!*val && !*ref) return 0; if (!*val) { if (*ref == '~') return +1; else return -1; } if (!*ref) { if (*val == '~') return -1; else return +1; } } } #endif bool RunTest(const char *File) { ifstream F(File,ios::in | ios::nocreate); if (!F != 0) return false; char Buffer[300]; int CurLine = 0; while (1) { F.getline(Buffer,sizeof(Buffer)); CurLine++; if (F.eof() != 0) return true; if (!F != 0) return _error->Error("Line %u in %s is too long",CurLine,File); // Comment if (Buffer[0] == '#' || Buffer[0] == 0) continue; // First version char *I; char *Start = Buffer; for (I = Buffer; *I != 0 && *I != ' '; I++); string A(Start, I - Start); if (*I == 0) return _error->Error("Invalid line %u",CurLine); // Second version I++; Start = I; for (I = Start; *I != 0 && *I != ' '; I++); string B(Start,I - Start); if (*I == 0 || I[1] == 0) return _error->Error("Invalid line %u",CurLine); // Result I++; int Expected = atoi(I); int Res = pkgVersionCompare(A.c_str(),B.c_str()); int Res2 = verrevcmp(A.c_str(),B.c_str()); cout << "'" << A << "' ?
