From 2128d3fce44da34ecb1f0d784b703807f66b20f9 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sun, 9 Jun 2013 18:33:48 +0200 Subject: fail in CopyFile if the FileFds have error flag set Testing for global PendingErrors in users of CopyFile is incorrect in so far as unrelated errors will prevent us from copying perfectly fine files and checking for the validity of the files is just better in CopyFiles as it already checks if files are at least opened. Add also a higher-level error message to the error stack if it fails. --- apt-pkg/contrib/fileutl.cc | 3 ++- apt-pkg/indexcopy.cc | 6 ++---- debian/changelog | 1 + 3 files changed, 5 insertions(+), 5 deletions(-) diff --git a/apt-pkg/contrib/fileutl.cc b/apt-pkg/contrib/fileutl.cc index 7c3a302e2..0f88923cf 100644 --- a/apt-pkg/contrib/fileutl.cc +++ b/apt-pkg/contrib/fileutl.cc @@ -184,7 +184,8 @@ bool RunScripts(const char *Cnf) /* The caller is expected to set things so that failure causes erasure */ bool CopyFile(FileFd &From,FileFd &To) { - if (From.IsOpen() == false || To.IsOpen() == false) + if (From.IsOpen() == false || To.IsOpen() == false || + From.Failed() == true || To.Failed() == true) return false; // Buffered copy between fds diff --git a/apt-pkg/indexcopy.cc b/apt-pkg/indexcopy.cc index 0e36b3ded..1d61b974d 100644 --- a/apt-pkg/indexcopy.cc +++ b/apt-pkg/indexcopy.cc @@ -544,11 +544,9 @@ bool SigVerify::CopyMetaIndex(string CDROM, string CDName, /*{{{*/ FileFd Rel; Target.Open(TargetF,FileFd::WriteAtomic); Rel.Open(prefix + file,FileFd::ReadOnly); - if (_error->PendingError() == true) - return false; if (CopyFile(Rel,Target) == false) - return false; - + return _error->Error("Copying of '%s' for '%s' from '%s' failed", file.c_str(), CDName.c_str(), prefix.c_str()); + return true; } /*}}}*/ diff --git a/debian/changelog b/debian/changelog index 42a8e540e..cde0aba2f 100644 --- a/debian/changelog +++ b/debian/changelog @@ -13,6 +13,7 @@ apt (0.9.8.3) UNRELEASED; urgency=low * set Fail flag in FileFd on all errors consistently * don't explicitly init ExtractTar InFd with invalid fd * OpenDescriptor should autoclose fd always on error (Closes: #704608) + * fail in CopyFile if the FileFds have error flag set -- David Kalnischkies Sun, 09 Jun 2013 15:06:24 +0200 -- cgit v1.2.3
