zlib

问题 I have a Python script where I need to extract the contents of a ZIP file. However, the zip file is over 6GB in size. There is a lot of information about zlib and zipfile modules, however, I can't find a single approach that works in my case. I have the code: with zipfile.ZipFile(fname, "r") as z: try: log.info("Extracting %s " %fname) head, tail = os.path.split(fname) z.extractall(folder + "/" + tail) except zipfile.BadZipfile: log.error("Bad Zip file") except zipfile.LargeZipFile: log.error

问题 I'm using the zlib.NET library to try and inflate files that are compressed by zlib (on a Linux box, perhaps). Here's what I'm doing: zlib.ZInputStream zinput = new zlib.ZInputStream(File.Open(path, FileMode.Open, FileAccess.Read)); while (stopByte != (data = zinput.ReadByte())) { // check data here } zinput.Close(); The data bytes match the compressed data bytes, so I must be doing something wrong. 回答1: Other than failing to use a "using" statement to close the stream even in the face of an

问题 In Python 2.5 I stored data using this code: def GLWriter(file_name, string): import cPickle import zlib data = zlib.compress(str(string)) file = open(file_name, 'w') cPickle.dump(data, file) It worked fine, I was able to read that data by doing that process in reverse. It didn't need to be secure, just something that wasn't readable to the human eye. If I put "test" into it and then opened the file it created, it looked like this: S'x\x9c+I-.\x01\x00\x04]\x01\xc1' p1 . For various reasons we

问题 I've been googling around for a zlib sample of how to decode gzip/deflate http encoding by only using ZLib unit (Delphi 7). I've been using Indy 10 for that but then I ran into an article saying many 3rd party components implemented their own zlib helpers eventually causing multiple zlib objects linked into the output file. I have this huge project and looking for ways to reduce the size. I did a search on the binary and turned out I had at least 4 copies of zlib linked in. Is there a way to

问题 I have a project I want to build with CMake and compile with MinGW. The project uses Zlib. When I build with CMake I get no errors but then when I run MinGW Make it gives the following output: C:\Projects\MultiMCBuild>C:\Qt\Tools\mingw492_32\bin\mingw32-make.exe . . . [ 50%] Linking CXX shared library ..\libMultiMC_logic.dll C:/Projects/MultiMCBuild/External/Install/QuaZIP/lib/libquazip.a(unzip.c.obj):unzip.c:(.text+0x1f6c): undefined reference to 'z_inflateEnd' C:/Projects/MultiMCBuild

问题 I've been supplied with a zipped file containing multiple individual streams of compressed XML. The compressed file is 833 mb. If I try to decompress it as a single object, I only get the first stream (about 19 kb). I've modified the following code supplied as a answer to an older question to decompress each stream and write it to a file: import zlib outfile = open('output.xml', 'w') def zipstreams(filename): """Return all zip streams and their positions in file.""" with open(filename, 'rb')

问题 I need to compile libxml2 32-bit and 64-bit binaries for my TeamSpeak 3 plugin because I could not find a dll/lib 64-bit download. When I use my compiled libxml2.dll as a dependency in a command prompt application, it works just fine. However, when I try to use it as a dependency in TeamSpeak 3, the program immediately crashes on launch. Specifically it crashes on this line: https://github.com/NobleUplift/TeamSpeak3WebsitePreview/blob/master/ts3websitepreview/plugin.c#L148 This is my batch

问题 I require zlib library for the development of Windows Store app. Has anyone converted Win32 zlib project to WinRT yet? Can anyone please describe the steps to convert the existing win32 static lib project to winRT? 回答1: Visual C++ is already a supported language for WinRT development, if you wan't to use zlib, just compile it together with your solution. There is nothing that is preventing you from reusing standard ISO C and C++ libraries from within the WinRT, if you are using the C++

问题 I am working on some code that builds simple palette based PNG files without libpng. The output file, at this stage only has IHDR, PLTE, IDAT(x3) and IEND chunks. The only thing which is possibly a bit different in that the pixel index values in the IDAT chunk are not compressed, that is the various zlib / block header bytes are as follows. CMF = 0x78. FLG = 0x9C (have also a few other values here but always with bit 5 clear). Block header byte = 0x01 (BFINAL = 1, BTYPE = 00). From what I can

问题 Greetings, I'm trying to analyze the output of the zlib(gzip) algorithm compared to the input. Determine stuff like dictionary size, the substring run-length pairs and where they correspond in the original plaintext. I'm using zlib to exchange many very small chunks of data (under 1K each), and want to determine overhead from the dictionary, a percentage of substring matches vs. dictionary-encoded plaintext in the results, that sort of thing. After a quick googling didn't yield results, I'm
