From bb93178b8b5c2f8021977dbc34066f0d0fb8b9b9 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Tue, 15 Apr 2014 10:21:52 +0200 Subject: clear HitEof flag in FileFd::Seek fseek and co do this to their eof-flags and it is more logic this way as we will usually seek away from the end (e.g. to re-read the file). The commit also improves the testcase further and adds a test for the binary compressor codepath (as gz, bzip2 and xz are handled by libraries) via the use of 'rev' as a 'compressor'. --- apt-pkg/contrib/fileutl.cc | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'apt-pkg/contrib') diff --git a/apt-pkg/contrib/fileutl.cc b/apt-pkg/contrib/fileutl.cc index c9d419fc4..de73a7fd8 100644 --- a/apt-pkg/contrib/fileutl.cc +++ b/apt-pkg/contrib/fileutl.cc @@ -1360,7 +1360,10 @@ bool FileFd::OpenInternDescriptor(unsigned int const Mode, APT::Configuration::C Args.push_back(a->c_str()); if (Comp == false && FileName.empty() == false) { - Args.push_back("--stdout"); + // commands not needing arguments, do not need to be told about using standard output + // in reality, only testcases with tools like cat, rev, rot13, … are able to trigger this + if (compressor.CompressArgs.empty() == false && compressor.UncompressArgs.empty() == false) + Args.push_back("--stdout"); if (TemporaryFileName.empty() == false) Args.push_back(TemporaryFileName.c_str()); else @@ -1653,6 +1656,8 @@ bool FileFd::Write(int Fd, const void *From, unsigned long long Size) /* */ bool FileFd::Seek(unsigned long long To) { + Flags &= ~HitEof; + if (d != NULL && (d->pipe == true || d->InternalStream() == true)) { // Our poor man seeking in pipes is costly, so try to avoid it -- cgit v1.2.3
