A problem regarding QuaZip

Hi,

I'm using QuaZip to archive my files like the following;

Code:

---

QByteArray LoggerManager::packFiles(const QString& p_name, const QByteArray& p_BytesToBrCompressed)
{
	QString testZip = p_name;
    QuaZip zip(testZip);
 
    zip.setFileNameCodec("IBM866"); /* or Windows-1250 */
 
    if(!zip.open(QuaZip::mdCreate))
	{
        qWarning("testCreate(): zip.open(): %d", zip.getZipError());
		return NULL;
    }
 
	QString loc = qApp->applicationDirPath() + "/logs/error_log/";
 
    QFileInfoList files=QDir(loc).entryInfoList();
    QFile inFile;
    QFile inFileTmp;
    QuaZipFile outFile(&zip);
    char c;
	QByteArray compressedData = "";
 
    foreach(QFileInfo file, files)
	{
        if(!file.isFile())
			continue;
 
        inFileTmp.setFileName(file.fileName());
        inFile.setFileName(file.filePath());
 
        if(!inFile.open(QIODevice::ReadOnly))
		{
			qWarning("testCreate(): inFile.open(): %s", inFile.errorString().toLocal8Bit().constData());
			return NULL;
        }
 
        if(!outFile.open(QIODevice::WriteOnly, QuaZipNewInfo(inFileTmp.fileName(), inFile.fileName())))
		{
 
			qWarning("testCreate(): outFile.open(): %d", outFile.getZipError());
			return NULL;
        }
 
        while(inFile.getChar(&c)&&outFile.putChar(c));
 
        if(outFile.getZipError()!=UNZ_OK)
		{
			qWarning("testCreate(): outFile.putChar(): %d", outFile.getZipError());
			return NULL;
        }
 
	compressedData = outFile.readAll();
 
        outFile.close();
 
		if(outFile.getZipError()!=UNZ_OK)
		{
			qWarning("testCreate(): outFile.close(): %d", outFile.getZipError());
			return NULL;
        }
 
        inFile.close();
    }
 
    zip.close();
 
    if(zip.getZipError()!=0) 
	{
        qWarning("testCreate(): zip.close(): %d", zip.getZipError());
		return NULL;
    }
 
    return compressedData;
}

The problem is; I want to send this zipped content to an HTTP server. But

Code:

---

compressedData = outFile.readAll();

---

is non-sense since outFile is writeOnly which makes compressedData empty string.

I try the following to overcome this situation;

Code:

---

QFile reader(p_name);
		if(QFile::exists(reader.fileName()))
		{
			if(reader.open(QIODevice::ReadOnly))
			{
				compressedData.append(reader.readAll());
			}
		}

But it didn't work either..

Any ideas?

Does the server support only HTTP? FTP would be better.

Is the archive read-only file (in the file system) or do you mean its only the attribute with which you open the QFile object, but the file it self is not read-only?

By "not working" do you mean compressData is empty?

Yepp!

arcihive is opened write-only by default. That's why I can't read it. And I opened QFile object ad read-only by myself.

Sorry..Yes.

and you are sure (by means of stepping trough or debug message) that:
compressedData.append(reader.readAll());
is being called?

Yeah, definitely...

What is the size of the file when you look it up with a file manager?
What is the size of the file when you do reader.size()?

it's size seems completely logical to me. About 20000 bytes.

And you can't reopen it in read only mode after you're done creating the archive?

Hi,

I'm very sorry to take your time but my problem caused by VS 2010 debugger. I was actually reading the file contents properly but the debugger doesn't show me. When I did qDebug, I saw all the contents of the file that i'm reading.

thanks for your care.
