gzip and zlib use slightly different headers. See How can I decompress a gzip stream with zlib? Try d = zlib.decompressobj(16+zlib.MAX_WBITS). And you might try changing your chunk size to a power of 2 (say CHUNKSIZE=1024) for possible performance reasons.
Try to re-install libtool by: brew reinstall libtool –universal && brew unlink libtool && brew link libtool If that doesn’t help, try removing libtool completely, and then retry the steps above: brew uninstall libtool If it still doesn’t work after trying the steps above, check to see if you have the DYLD_FALLBACK_LIBRARY_PATH variable defined somewhere … Read more
zlib.h has all the functions you need: compress (or compress2) and uncompress. See the source code of zlib for an answer. ZEXTERN int ZEXPORT compress OF((Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen)); /* Compresses the source buffer into the destination buffer. sourceLen is the byte length of the source buffer. Upon entry, destLen … Read more
response.on(‘data’, …) can accept a Buffer, not just plain strings. When concatenating you are converting to string incorrectly, and then later can’t gunzip. You have 2 options: 1) Collect all the buffers in an array, and in the end event concatentate them using Buffer.concat(). Then call gunzip on the result. 2) Use .pipe() and pipe … Read more
Try using the zip:// wrapper: $handle = fopen(‘zip://test.zip#test.txt’, ‘r’); $result=””; while (!feof($handle)) { $result .= fread($handle, 8192); } fclose($handle); echo $result; You can use file_get_contents too: $result = file_get_contents(‘zip://test.zip#test.txt’); echo $result;
For anybody stumbling on this in 2016 (and also wondering how to serialize compressed data to a string rather than a file or a buffer) – it looks like zlib (since node 0.11) now provides synchronous versions of its functions that do not require callbacks: var zlib = require(‘zlib’); var input = “Hellow world”; var … Read more
zlib handles the deflate compression/decompression algorithm, but there is more than that in a ZIP file. You can try libzip. It is free, portable and easy to use. UPDATE: Here I attach quick’n’dirty example of libzip, with all the error controls ommited: #include <zip.h> int main() { //Open the ZIP archive int err = 0; … Read more
Openssl on mac is compiled without zlib support. Alternative method described in this article works on my Yosemite: dd if=backup.ab bs=1 skip=24 | python -c “import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))” | tar -xvf – Optionaly, if you just want to convert it into tar archive: dd if=backup.ab bs=1 skip=24 | python -c “import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))” > backup.tar It skips … Read more
On Mojave, after installing Xcode command line tools, had to run the following: sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Just run in the command line: xcode-select –install In OS X 10.9+, the command line developer tools are now installed on demand. So after running this also zlib and zlib-devel should be available (no need for brew install zlib…)
