Hi, I'm the package maintainer for Arch Linux and got this warning after the GCC 8.1 upgrade: ```cpp /home/gizdov/Packages/builds/xrootd/src/xrootd-4.8.3/src/XrdApps/XrdCpFile.cc: In constructor ‘XrdCpFile::XrdCpFile(const char*, int&)’: /home/gizdov/Packages/builds/xrootd/src/xrootd-4.8.3/src/XrdApps/XrdCpFile.cc:91:20: error: ‘char* strncpy(char*, const char*, size_t)’ output may be truncated copying 8 bytes from a string of length 8 [-Werror=stringop-truncation] strncpy(ProtName, pTab[i].pHdr, sizeof(ProtName)); ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1plus: all warnings being treated as errors ``` which prevents the build. I could overwrite the `-Werror` flag, but I'd rather keep it as the dev intended. For the moment, I have patched the issue with the following: ```diff diff -aur xrootd-4.8.3-old/src/XrdApps/XrdCpFile.cc xrootd-4.8.3-new/src/XrdApps/XrdCpFile.cc --- xrootd-4.8.3-old/src/XrdApps/XrdCpFile.cc 2018-05-13 19:01:03.602433537 +0200 +++ xrootd-4.8.3-new/src/XrdApps/XrdCpFile.cc 2018-05-13 19:01:48.269454421 +0200 @@ -88,7 +88,7 @@ for (i = 0; i < pTnum; i++) {if (!strncmp(FSpec, pTab[i].pHdr, pTab[i].pHsz)) {Protocol = pTab[i].pVal; - strncpy(ProtName, pTab[i].pHdr, pTab[i].pHsz-3); + memcpy(ProtName, pTab[i].pHdr, pTab[i].pHsz-3); return; } } ``` Just wanted to make sure this is appropriate and then I can submit a pull request. Thanks. -- You are receiving this because you are subscribed to this thread.
