From 716e748b2fe86beba88b390f4e6c81d2e268035a Mon Sep 17 00:00:00 2001 From: Michael Wetherell Date: Sun, 18 Dec 2005 13:58:55 +0000 Subject: [PATCH] In the past some streams returned Eof() before the end was read past rather after, and also some streams give an error instead of Eof(). Test the archive streams work with parent streams that have any of these behaviours. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@36429 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- tests/archive/archivetest.cpp | 62 +++++++++++++++++++++++------------ tests/archive/archivetest.h | 31 +++++++++++++++--- tests/archive/ziptest.cpp | 19 ++++++----- 3 files changed, 77 insertions(+), 35 deletions(-) diff --git a/tests/archive/archivetest.cpp b/tests/archive/archivetest.cpp index 4178574e86..379950a5d5 100644 --- a/tests/archive/archivetest.cpp +++ b/tests/archive/archivetest.cpp @@ -196,7 +196,8 @@ TestInputStream::TestInputStream(const TestInputStream& in) : wxInputStream(), m_options(in.m_options), m_pos(in.m_pos), - m_size(in.m_size) + m_size(in.m_size), + m_eoftype(in.m_eoftype) { m_data = new char[m_size]; memcpy(m_data, in.m_data, m_size); @@ -251,16 +252,28 @@ size_t TestInputStream::OnSysRead(void *buffer, size_t size) { if (!IsOk() || !size) return 0; - if (m_size <= m_pos) { - m_lasterror = wxSTREAM_EOF; - return 0; + + size_t count; + + if (m_pos >= m_size) + count = 0; + else if (m_size - m_pos < size) + count = m_size - m_pos; + else + count = size; + + if (count) { + memcpy(buffer, m_data + m_pos, count); + m_pos += count; } - if (m_size - m_pos < size) - size = m_size - m_pos; - memcpy(buffer, m_data + m_pos, size); - m_pos += size; - return size; + if (((m_eoftype & AtLast) != 0 && m_pos >= m_size) || count < size) + if ((m_eoftype & WithError) != 0) + m_lasterror = wxSTREAM_READ_ERROR; + else + m_lasterror = wxSTREAM_EOF; + + return count; } @@ -424,17 +437,16 @@ PFileOutputStream::~PFileOutputStream() template ArchiveTestCase::ArchiveTestCase( string name, - int id, ClassFactoryT *factory, int options, const wxString& archiver, const wxString& unarchiver) : - CppUnit::TestCase(name), + CppUnit::TestCase(TestId::MakeId() + name), m_factory(factory), m_options(options), m_timeStamp(1, wxDateTime::Mar, 2004, 12, 0), - m_id(id), + m_id(TestId::GetId()), m_archiver(archiver), m_unarchiver(unarchiver) { @@ -464,7 +476,7 @@ void ArchiveTestCase::runTest() // check archive could be created CPPUNIT_ASSERT(out.GetLength() > 0); - TestInputStream in(out); + TestInputStream in(out, m_id % ((m_options & PipeIn) ?
