It works correctly with FileOutputStream with parameter 'true'. result = item.extractSlow(new ISequentialOutStream() { @SneakyThrows public int write(byte[] data) throws SevenZipException { FileOutputStream wr = null; try { wr = new FileOutputStream("c:\\Users\\1\\tt.pdf", true); wr.write(data); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally { if (wr != null) {...

Hi Boris. In case, thank you very much for all your contribution with this solution. I have been facing a problem in the simultaneous execution of my project when trying to compress different files in different executions. And getting a FATAL ERROR that doesn't let me catch the error or be able to do anything. I have tried these 2 actions. 1) Instantiate the 7Zip object only once when starting my project.

Boris Brodski posted a comment on discussion Help
Hey, how did you solve it? There is nothing to solve. It works like this: You have test.txt file When you compress your file to bzip2 you get test.txt.bz2 In the file content there is no name "test.txt" encoded This means, if you rename your file to abc.bz2 it will be not possible to recover the original name "test.txt". Extracting "abc.bz2" with 7z would you give file "abc", not "test.txt". I hope, it helps clarify situation.
-
Actually, it should be pretty straight forward. Just extract gz into a temporary file, then open it and extract again.
-
It would be cool to write such code and share it. But don't have something working out of the box yet. I created an issue https://github.com/borisbrodski/sevenzipjbinding/issues/53

"You have to extract this Gzip archive first and then open the result again." can you share code for this?

Hi Ami, I don't see any good alternative. what you can do: you can start the extraction of one item, then throw an exception after some bytes were extracted and passed to write () method to stop the process. Then try the next item. Cheers Boris

Ok, your code has a big problem. The method write of the ISequentialOutStream get called multiple times for one archive item. Imagine, you have a file 1T in size that you want to extract. It is impossible to put 1T in one Java array. So the write() method get called many times passing chunks of the file to you.

You asked about ZIP files :) is there any method which check given zip file is password protected or not For 7z and RAR archives this approach should be extended as following: - Use your own implementation of IArchiveOpenCallback that also implements ICryptoGetTextPassword - Try to open archive - If successful, the 7z or RAR archive itself is not password protected - If cryptoGetTextPassword() get called, the entire archive is password protected Now proceed with the same stratagy extracting archive...
-
please find 7z file, i tried above mentioned approach but unable to open this file because this 7z file itself password protected . if 7z file contains any Password protected files then we can go for this approach . but if 7z file itself is password protected , how can check for this ByteArrayStream byteStream = new ByteArrayStream(IOUtils.toByteArray(is), true); inArchive = SevenZip.openInArchive(null, // autodetect archive type byteStream); System.out.println(" Hash | Size | Filename"); System.out.println("----------+------------+---------");...
-
Hello, hm, I might be useful, but no, we don't have it. But you can just try to open an archive and then extract first item (implementing both IArchiveExtractCallback and ICryptoGetTextPassword in your callback ) . If you get asked for the password, the archive item is password protected and you can cancel the extraction process by throwing an exception. Keep in mind, that some archive items might be password protected and some not. Cheers, Boris
-
Hello Akanksha, you don't need to have a file on the system in order to extract an archive with 7-Zip-JBinding. But InputStream is not enough. Extracting archives, like RAR, involves jumping through data. Java InputStream unfortunatelly allows only sequential access to the data. The best way is to implement InStream interface with read and seek method. Cheers, Boris

Hi, Is there an option or will be to use 7-zip-JBinding to open files packed with tar with option J (meaning xz)? Cuz I have a code just like examples and unpacking tar files is OK, but files packed this way: tar -cJvf archive.tar.xz file it is impossible. Would be greatful for reply.

Hi Rob, BlockingQueue sounds good for me. Just be careful with the read and write methods of sequential streams. These methods are not always consume or produce the entire given array. Here is a quote from the read()-docs: This function is allowed to read less than number of remaining bytes in stream and less then data.length. You must call read() function in loop, if you need exact amount of data. Best regards, Boris
-
Hi Boris, First of all, thank you for your quick reply. Moreover, the library is very useful especially now that unrar has been removed from centos/redhat distros. This morning, after my post, I read one of your replies and thought of using BlockingQueue to implement Producer/Consumer logic with two different threads. In this way, I'll extract and compress the first chunk creating the first version of the compressed file (createArchive function), then I'll append the following chunks using the updateArchive...
-
Hi, yes, 7-Zip-JBinding was designed with such capabilities in mind. In order to do this you don't need ByteArrayStream. The trick is to use two threads: producer and consumer. Producer thread extracts your original archive and produces 4096 bytes of extracted content. Consumer wait for 4096 bytes to become ready, then it compresses it. You have to keep track of overall process, stop the threads on the end-of-file and also pass some properties around, like file names and file sizes. Please, read...

William Rantis posted a comment on ticket #12
Ah, sorry. I tried extracting with 7z and found that the dataerror I was getting was the same as with 7-zip-JBinding. I was previously getting unsupportedmethod when I tried to open the password protected archive without a password. Getting a dataerror must be because using of using a wrong password with an encrypted file while the file headers aren't encrypted.
-
Hello William, LZMA2 is supported. If you have any extraction issues, please: try the last version: 16.02-2.01. try to manually extract your file with the corresponding 7z version (16.02) If it is a 7-Zip-JBinding and not 7z problem: Upload your file, so I can reproduce the problem (or create another one showing the same effect) Post relevant code snippets Cheers, Boris

Hello Vladimir, sorry for late response. Just read your post. There is no close method on the call back. "sevenZip.ExtractCallbackFromSevenZip" is your class, right.

Hello Boris, I think you can just use an URLClassloader (to load the sevenzip jars), set it as the context classloader from the current thread and then let it load SevenZip things from another class afterwards? Just make sure your classes are not on the system classloader classpath? That should trigger the crash without spring? If you want, I can try to come up with something as well. A check in the init routines would definitely be a good start to prevent the jvm crashing afterwards. Can the 'no...

Hi Silas, good questions. I think it all depends on compressors. Using lzma or zip or other compression you may get different behavior. But I would expect following behavior: getStream(int index) get called at most ones for each index All streams CAN be closed in setOperationResult() both in OK and ERROR case Due to some errors setOperationResult() may be not called, all stream SHOULD be closed in the "finally" block around the 7-zip createArchive() or updateArchive() call. In OK case all streams...

Hello, you are right. A better error message is needed here. Although there are also other reasons possible. If no classes can be found, not crashing JVM and returning control to the java code can be very tricky. I could add an simple class loading test in the initialization routine, where detecting such errors is easier. Any idea how I could test it in a simple way and without using spring? (I could implement my own classloader, but may be you are aware of some existing simple implementations) Thank...

Hello Boris, Thanks for your response. This workaround is kind of ok, but would it be possible to give a more sensible error or exception? Currently, this issue crashes the JVM, and I saw in your source code that you do that to get a stacktrace from the jvm? However, here it only crashes with that text "Crash jvm to get a stack trace" and then the process exits. Would be nice to have an exception, or initialization check, or callback to handle this properly from the java side? Kind regards, Silas...
