archive

I'm using Perl's Archive::Tar module. Problem with it is it pulls everything on to the memory and the does archiving and then writes on to the file system so there is limitation on the maximum file size that can be archived. Most of the times it says out of memory. In case of GNU tar, it takes chunk of file, archives it and writes it on to the memory so it can handle files of any size. How can I do that using Perl's Archive::Tar module. It looks like there is a different module that doesn't use an in-memory structure: Archive::Tar::Streamed . The downside is that it requires tar to be

I'm working on a commercial project that requires a couple of files to be bundled (packed) into an archive and then compressed. Right now we have zlib in our utility library, but it doesn't look like zlib has the functionality to compress multiple files into one archive. Does anyone know of free libraries I'd be able to use for this? Amber Perhaps libtar ? Also under a BSD license. 7Zip has a full SDK for several languages including C and C++. The compression is extremely good, albeit not very fast. The code is licensed under the LGPL. You could use libzip - it's under a BSD-like licence so it

I have several folders with files, some folders contain non-latin symbols in their names (russian in my case). This folders are sending to zip archive (by windows explorer) in "D:\test.zip". Then I execute method ZipFile.ExtractToDirectory(@"D:\test.zip", @"D:\result"); and it successfully unzip all content, but all non-latin symbols turn into something wrong. For example, instead of "D:\result\каскады\file.txt" I got "D:\result\Є бЄ ¤л\file.txt" . Default encoding of my system is windows-1251 which I verified by involving Encoding.GetEncoding("windows-1251") into third parameter of

I have to frequently search through a couple of .7z (zipped with LZMA) files. I don't have enough memory to have them unpacked at the same time or to change the archive to .gz. At the moment I unpack one, search for what I need, delete what was extracted, unpack the next. I want to go through the archives in the same way as with gzip: f = gzip.open('archive.gz') for i in f: do stuff Is there a module/way to do this with .7z files? There is a built in module in Python >= 3.3: http://docs.python.org/3.3/library/lzma And there is also a backport of the module on the PyPI: https://pypi.python.org

I'm looking for a solution to archive data that exists in my database. My database is SQL Server 2008 and have approximately 250 tables. I search web and find the below link : http://www.dbazine.com/sql/sql-articles/charran13/ but this solution is not clear I don't know that is there a direct way for doing this in sql server. please give me a solution. The solution that you choose to rollout will be dependent on your reasons for implementing data archival. For example you will need to consider: What data is to be archived? For example all data or data older than a certain date? This has

I am integrating XMPP functionality in my ios app and i came across a problem i cannot solve. The problem is i cannot get archived messages from the server. My client is able to log in and i have tested several service calls (send, receive messages, getting info about a user) with success. Upon sending <iq type='get' id='pref1'> <pref xmlns='urn:xmpp:archive'/> </iq> The response is SEND: <iq type="get"><pref xmlns="urn:xmpp:archive"/></iq> RECV: <iq xmlns="jabber:client" type="error" to="1@iis2/ae76edc"><error code="501" type="cancel"><feature-not-implemented xmlns="urn:ietf:params:xml:ns

I use 7zip to create the SFX as follows: 7z.exe a -r archive.7z * Then I do a binary copy with the 7zS.sfx file (used to create a self extracting installer), config file "build.config", and the archive. The contents of config file are as follows: ;!@Install@!UTF-8! RunProgram="setup.exe" GUIMode="1" Path="%tmp%\\mytemp" ;!@InstallEnd@! Binary copy command is as follows: copy /b 7zS.sfx + build.config + archive.7z sfxInstaller.exe Problem is that the result SFX "sfxInstaller.exe" requires admin privileges for executing. Is it possible to generate Self Extracting Archives using 7-Zip that do not
