It uses Trolltech's - * Qt toolkit. - * - * If you do not know what Qt is, you have two options: - * - Just forget about QuaZIP. - * - Learn more about Qt by downloading it and/or reading excellent official Qt documentation - * - * The choice is yours, but if you are really interested in - * cross-platform (Windows/Linux/BSD/UNIX/Mac/Others) software - * development, I would definitely recommend you the second choice ^_^ - * - * QuaZIP allows you to access files inside ZIP archives using QIODevice - * API, and - yes! - that means that you can also use QTextStream, - * QDataStream or whatever you would like to use on your zipped files. - * - * QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both - * reading from and writing to ZIP archives. - * - * \section platforms Platforms supported - * - * QuaZIP has been currently tested with Qt 4.0.0 on the following - * platforms: - * - linux-g++ - * - freebsd-g++ - * - hpux-acc - * - win32-g++ (MinGW) - * - * No testing has been done on other systems. Of course, patches to - * make it work on any platform that it currently does not work on are - * always welcome! - * - * \section whats-new What is new in this version of QuaZIP? - * - * See NEWS file supplied with the distribution. - * - * \section getting Getting latest version of QuaZIP - * - * Check QuaZIP - * project's page at SourceForge.net. Also, you may wish to read - * latest version documentation available at the QuaZIP web site. - * - * \section Requirements - * - * Just zlib and Qt 4. Well, Qt 4 - * depends on zlib anyway. - * - * \section building Building, testing and installing - * - * \note Instructions given in this section assume that you are - * using some UNIX dialect, but the build process should be very similar - * on win32-g++ platform too. Sorry, but other platforms are - * undocumented. I do not think it is a big deal, though - it is - * standard usage of the Qt's qmake, so you most probably already know - * everything that is required. - * - * To build it on some UNIX dialect: -\verbatim -$ cd /wherever/quazip/source/is/quazip-x.y.z/quazip -$ qmake [PREFIX=where-to-install] -$ make -\endverbatim - * - * Make sure that you have Qt 4 installed with all required headers and - * utilities (not just library) and that you run qmake utility of the Qt - * 4, not some other version you may have already installed (you may - * need to type full path to qmake like /usr/local/qt4/bin/qmake). - * - * To reconfigure (with another PREFIX, for example), just run qmake - * with appropriate arguments again. - * - * If you need to specify additional include path or libraries, use - * qmake features (see qmake reference in the Qt documentation). For - * example: - * -\verbatim -$ qmake LIBS+=-L/usr/local/zlib/lib INCLUDEPATH+=/usr/local/zlib/include -\endverbatim - * (note abscence of "-I" before include path) - * - * To check if QuaZIP's basic features work ok on your platform, you may - * wish to compile simple test programs provided in test directory. - * Look in the sources of the tests to find out about their - * requirements. Typically, the test looks something like this: -\verbatim -$ cd /wherever/quazip/source/is/quazip-x.y.z/test/zip -$ qmake -$ make -$ ./zip -$ cd ../unzip -$ cp ../zip/test.zip ./test.zip -$ mkdir out -$ qmake -$ make -$ ./unzip -\endverbatim - * - * You should see the zip contents with details as the output of the - * "./unzip". Ignore message saying you should check the file name for - * testCase() if you do not want to test - * \link QuaZip::CaseSensitivity locale-aware case-insensitivity\endlink. - * Otherwise, see the sources. In any case, this message appearing means - * that everything else was fine. Otherwise, you will get some other error - * message instead. Investigate it or send bug report including message, - * platform and QuaZIP version used. - * - * To install compiled library: -\verbatim -$ make install -\endverbatim - * - * By default, QuaZIP compiles as static library, but you have other - * options: - * - Just copy appropriate source files to your project and use them; - * - Compile QuaZIP as shared library by changing "staticlib" in - * quazip/quazip.pro to "dll". - * - * Latter is not recommended because future versions of QuaZIP most - * probably will be binary incompatible. - * - * \section using Using - * - * See \ref usage "usage page". - * - * \section bugs Bugs - * - * QuaZIP is currently at the initial development stage. Therefore, - * there are may be plenty of bugs and other bad things. Bug reports and - * patches are always welcome (see "contacts" below). - * - * \section contacts Authors and contacts - * - * This wrapper has been written by Sergey A. Tachenov, AKA Alqualos. - * This is my first open source project, so it may suck, but I did not - * find anything like that, so I just had no other choice but to write - * it. - * - * If you have anything to say to me about QuaZIP library, feel free to - * do so (read the \ref faq first, though). I can not promise, - * though, that I fix all the bugs you report in, add any features you - * want, or respond to your critics, or respond to your feedback at all. - * I may be busy, I may be tired of working on QuaZIP, I may be even - * dead already (you never know...). But regardless of this remark, any - * feedback is always welcome. This may seem like a paradox to you, but - * you do not have to understand it to write feedback. - * - * To report bugs or to post ideas about what should be done, use - * SourceForge.net's trackers. - * If you want to send me a private message, use my e-mail address - * laerel at yandex dot ru (but do not you dare to put it somewhere on - * the Web or wherever). - * - * Do not use e-mail to report bugs, please. Reporting bugs and problems - * with the SourceForge.net's bug report system has that advantage that - * it is visible to public. - * - * \section other-projects My other projects - * - * As of this moment, I did not write any other useful open source - * software (well, I am too lazy to do it) except for one little thing: - * - * Arcanum - * universal cap remover.

I did not alter it in any way to make it easier to - * port to the future ZIP/UNZIP versions. - * - * "ZIP", "ZIP archive" or "ZIP file" means any ZIP archive. Typically - * this is a plain file with ".zip" (or ".ZIP") file name suffix. - * - * "A file inside archive", "a file inside ZIP" or something like that - * means file either being read or written from/to some ZIP archive. - * - * \section error-handling Error handling - * - * Almost any call to ZIP/UNZIP API return some error code. Most of the - * original API's error checking could be done in this wrapper as well, - * but it would cause unnecessary code bloating without any benefit. So, - * QuaZIP only checks for situations that ZIP/UNZIP API can not check - * for. For example, ZIP/UNZIP API has no "ZIP open mode" concept - * because read and write modes are completely separated. On the other - * hand, to avoid creating classes like "QuaZipReader", "QuaZipWriter" - * or something like that, QuaZIP introduces "ZIP open mode" concept - * instead, thus making it possible to use one class (QuaZip) for both - * reading and writing. But this leads to additional open mode checks - * which are not done in ZIP/UNZIP package. - * - * Therefore, error checking is two-level (QuaZIP's level and ZIP/UNZIP - * API level), which sometimes can be confusing, so here are some - * advices on how the error checking should be properly done: - * - * - Both QuaZip and QuaZipFile have getZipError() function, which return - * error code of the last ZIP/UNZIP API call. Most function calls - * reset error code to UNZ_OK on success and set error code on - * failure. Some functions do not reset error code. Most of them are - * \c const and do not access ZIP archive in any way. Some, on the - * other hand, \em do access ZIP archive, but do not reset or set - * error code. For example, QuaZipFile::pos() function. Such functions - * are explicitly marked in the documentation. - * - Most functions have its own way to report errors, by returning a - * null string, negative value or \c false. If such a function returns - * error value, call getZipError() to get more information about - * error. See "zip.h" and "unzip.h" of the ZIP/UNZIP package for error - * codes. - * - If the function returns error-stating value (like \c false), but - * getZipError() returns UNZ_OK, it means that you did something - * obviously wrong. For example, tried to write in the archive open - * for reading or not open at all. You better just do not do that! - * Most functions also issue a warning using qWarning() function in - * such cases. See documentation for a specific function for details - * on when it should not be called. - * - * I know that this is somewhat messy, but I could not find a better way - * to do all the error handling. - **/ diff -r 845b5ae03841 -r 04dd8b7fb605 misc/quazip/ioapi.h --- a/misc/quazip/ioapi.h Sun Nov 18 00:37:23 2012 +0400 +++ /dev/null Thu Jan 01 00:00:00 1970 +0000 @@ -1,77 +0,0 @@ -/* ioapi.h -- IO base function header for compress/uncompress .zip - files using zlib + zip or unzip API - - Version 1.01e, February 12th, 2005 - - Copyright (C) 1998-2005 Gilles Vollant - - Modified by Sergey A.

But see QuaZipFile::QuaZipFile(QuaZip*, QObject*) - * for the possible pitfalls. - * - * This class is indended to provide interface to the ZIP subpackage of - * the ZIP/UNZIP package as well as to the UNZIP subpackage. But - * currently it supports only UNZIP. - * - * The use of this class is simple - just create instance using - * constructor, then set ZIP archive file name using setFile() function - * (if you did not passed the name to the constructor), then open() and - * then use different functions to work with it! Well, if you are - * paranoid, you may also wish to call close before destructing the - * instance, to check for errors on close. - * - * You may also use getUnzFile() and getZipFile() functions to get the - * ZIP archive handle and use it with ZIP/UNZIP package API directly. - * - * This class supports localized file names inside ZIP archive, but you - * have to set up proper codec with setCodec() function. By default, - * locale codec will be used, which is probably ok for UNIX systems, but - * will almost certainly fail with ZIP archives created in Windows. This - * is because Windows ZIP programs have strange habit of using DOS - * encoding for file names in ZIP archives. For example, ZIP archive - * with cyrillic names created in Windows will have file names in \c - * IBM866 encoding instead of \c WINDOWS-1251. I think that calling one - * function is not much trouble, but for true platform independency it - * would be nice to have some mechanism for file name encoding auto - * detection using locale information.

Not only it provides C++ - * interface to the ZIP/UNZIP package, but also integrates it with Qt by - * subclassing QIODevice. This makes possible to access files inside ZIP - * archive using QTextStream or QDataStream, for example. Actually, this - * is the main purpose of the whole QuaZIP library. - * - * You can either use existing QuaZip instance to create instance of - * this class or pass ZIP archive file name to this class, in which case - * it will create internal QuaZip object. See constructors' descriptions - * for details. Writing is only possible with the existing instance. - * - * Note that due to the underlying library's limitation it is not - * possible to use multiple QuaZipFile instances to open several files - * in the same archive at the same time. If you need to write to - * multiple files in parallel, then you should write to temporary files - * first, then pack them all at once when you have finished writing. If - * you need to read multiple files inside the same archive in parallel, - * you should extract them all into a temporary directory first. - * - * \section quazipfile-sequential Sequential or random-access? - * - * At the first thought, QuaZipFile has fixed size, the start and the - * end and should be therefore considered random-access device. But - * there is one major obstacle to making it random-access: ZIP/UNZIP API - * does not support seek() operation and the only way to implement it is - * through reopening the file and re-reading to the required position, - * but this is prohibitively slow. - * - * Therefore, QuaZipFile is considered to be a sequential device. This - * has advantage of availability of the ungetChar() operation (QIODevice - * does not implement it properly for non-sequential devices unless they - * support seek()). Disadvantage is a somewhat strange behaviour of the - * size() and pos() functions. This should be kept in mind while using - * this class. - * - **/ -class QUAZIP_EXPORT QuaZipFile: public QIODevice { - friend class QuaZipFilePrivate; - Q_OBJECT - private: - QuaZipFilePrivate *p; - // these are not supported nor implemented - QuaZipFile(const QuaZipFile& that); - QuaZipFile& operator=(const QuaZipFile& that); - protected: - /// Implementation of the QIODevice::readData(). - qint64 readData(char *data, qint64 maxSize); - /// Implementation of the QIODevice::writeData(). - qint64 writeData(const char *data, qint64 maxSize); - public: - /// Constructs a QuaZipFile instance. - /** You should use setZipName() and setFileName() or setZip() before - * trying to call open() on the constructed object. - **/ - QuaZipFile(); - /// Constructs a QuaZipFile instance. - /** \a parent argument specifies this object's parent object. - * - * You should use setZipName() and setFileName() or setZip() before - * trying to call open() on the constructed object. - **/ - QuaZipFile(QObject *parent); - /// Constructs a QuaZipFile instance. - /** \a parent argument specifies this object's parent object and \a - * zipName specifies ZIP archive file name. - * - * You should use setFileName() before trying to call open() on the - * constructed object. - * - * QuaZipFile constructed by this constructor can be used for read - * only access.

The end-of-block will not be indicated until all of the - uncompressed data from that block has been written to strm->next_out. The - number of unused bits may in general be greater than seven, except when - bit 7 of data_type is set, in which case the number of unused bits will be - less than eight. - - inflate() should normally be called until it returns Z_STREAM_END or an - error. However if all decompression is to be performed in a single step - (a single call of inflate), the parameter flush should be set to - Z_FINISH. In this case all pending input is processed and all pending - output is flushed; avail_out must be large enough to hold all the - uncompressed data. (The size of the uncompressed data may have been saved - by the compressor for this purpose.) The next operation on this stream must - be inflateEnd to deallocate the decompression state. The use of Z_FINISH - is never required, but can be used to inform inflate that a faster approach - may be used for the single inflate() call. - - In this implementation, inflate() always flushes as much output as - possible to the output buffer, and always uses the faster approach on the - first call. So the only effect of the flush parameter in this implementation - is on the return value of inflate(), as noted below, or when it returns early - because Z_BLOCK is used. - - If a preset dictionary is needed after this call (see inflateSetDictionary - below), inflate sets strm->adler to the adler32 checksum of the dictionary - chosen by the compressor and returns Z_NEED_DICT; otherwise it sets - strm->adler to the adler32 checksum of all output produced so far (that is, - total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described - below. At the end of the stream, inflate() checks that its computed adler32 - checksum is equal to that saved by the compressor and returns Z_STREAM_END - only if the checksum is correct. - - inflate() will decompress and check either zlib-wrapped or gzip-wrapped - deflate data.

The - fields next_in, zalloc, zfree and opaque must be initialized before by - the caller. - - The method parameter is the compression method. It must be Z_DEFLATED in - this version of the library. - - The windowBits parameter is the base two logarithm of the window size - (the size of the history buffer). It should be in the range 8..15 for this - version of the library. Larger values of this parameter result in better - compression at the expense of memory usage. The default value is 15 if - deflateInit is used instead. - - windowBits can also be -8..-15 for raw deflate. In this case, -windowBits - determines the window size. deflate() will then generate raw deflate data - with no zlib header or trailer, and will not compute an adler32 check value. - - windowBits can also be greater than 15 for optional gzip encoding. Add - 16 to windowBits to write a simple gzip header and trailer around the - compressed data instead of a zlib wrapper. The gzip header will have no - file name, no extra data, no comment, no modification time (set to zero), - no header crc, and the operating system will be set to 255 (unknown). If a - gzip stream is being written, strm->adler is a crc32 instead of an adler32. - - The memLevel parameter specifies how much memory should be allocated - for the internal compression state. memLevel=1 uses minimum memory but - is slow and reduces compression ratio; memLevel=9 uses maximum memory - for optimal speed. The default value is 8. See zconf.h for total memory - usage as a function of windowBits and memLevel. - - The strategy parameter is used to tune the compression algorithm. Use the - value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a - filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no - string match), or Z_RLE to limit match distances to one (run-length - encoding).
