[RELEASED] zip / gzip native multiplatfrom plugin

Good to know.
Thanks.

 

I'm getting a crash while trying to run in the iOS Simulator with this library:

dyld: lazy symbol binding failed: Symbol not found: _zipCompressBuffer

dyld: Symbol not found: _zipCompressBuffer

I'm using the latest version, even though supposedly the simulator has been supported since v1.5

 

Hello.

In the Plugins/iOS folder, there is a libzipw.a-simulator.zip archive which includes a simulator version of the plugin.

Have you used this to replace the libzipw.a plugin?

 

Hi, I am trying to deploy for UWP using IL2CPP but am running into a DllNotFoundException for libzipw when I try running and my app tries to unzip a downloaded file.

I am currently running in Release for x86 in Visual Studio. Any help would be appreciated. Thanks!

 

Hello. Which version of Unity? So I can test here.

 

I am using Unity 2018.2.17f1. If you could check if it works for you on the device, as well as the settings you use to deploy, that would be helpful for me to debug.

 

Ok.
I will check this later and get back to you.

 

Found a resolution - the DLLs for UWP somehow went missing from my project so I just reimported the package. Thanks!

 

Hi!

OSX store is no longer accepting 32 bits, so your plugin gets automatically rejected when uploading to the Mac App Store. I can manually fix it after each build, but it will be great if you can update the plugin and remove the 32 bits.

Thanks!

Albert

 

Thx for the heads up.
I will update.
Meanwhile I will send a build through a private message.

 

Hi - I've run into a problem. I'm unzipping a file on Android using the decompress_File method - it unzips fine, but when I try to read the file I get an error - "Sharing violation on path". There is no problem reading the file if the program is reloaded - and I think perhaps a file stream is left open on the file after it has unzipped. Would appreciate any help in solving this.

 

Hello.

I will investigate this and get back to you.

 

Thanks - looking forward to hearing from you.

 

Google Play will soon requires arm 64bits support as mandatory, please update the library as soon as you can, much thanks!

 

Hello.

Yes I will update very soon. The plugin rewrite was holding me back.
I guess I will make an intermediate update now.

But I can send you the arm64 binaries.
PM me for the link.

 

update version 1.5

- Addded arm64-v8a Android plugin.

- Resolved some il2cpp issues.

- Unicode filenames on decompression should work now on Windows.

- Removed WSA support.

 

Hi, Can we have details of extracted file directory, such as its name and files inside that?

Regards,
Ben

 

Hello.

You can get all the details of a zip file by using the getFileInfo function. (see demo.)

The extracted directory contents I believe it is easy to read on your own. Unless I misunderstood and you mean something else.

 

UPDATE

I forgot to add in the latest release notes that now you can decompress split zip archives.

For example winrar creates such split zip files like:

myZip.zip
myZip.z01
myZip.z02
myZip.z03

 

Hi,
nice work!
getting the plugin I was hoping to be able to compress and uncompress from a buffer but with the encryption, is there anyway to get this? I cannot find an way point for this without having to create a zip file on disk,
thanks!

 

Hi.

Right now you can have an existing encrypted zip archive in a buffer and decompress from there.
But there is not yet a function to compress to a buffer with encryption.

I will try to add this in a next update.

 

Hello!

Need your Help, please!

Let us know what could be done to solve the issue..

 

can we get the same build as well. we are having the same issue.

 

Hello.

The update will be updated today.

Check your pm for the build.

 

update version 1.52

- Added the ability to create split zip archives.

- Fixed an issue with the iOS bitcode enabled plugin.

 

Hello.
i just wonder how to decompress zip file on the other thread without be a sharing violation？Is snippets blow safe?

void AsyncDecompressFile()

        {

            _fileProcess = new int[1];      // thread1: Unity Main thread Update UI

            Thread thread = new Thread(() =>

            {

                // thread2: decompress process

                lzip.decompress_File("myfile.zip", "extracePath", _fileProcess, null, null);

            });

            thread.Start();

        }

 

Yes this should be safe.
Look also in the demo script for threaded call.

 

Hi:
AFAIK, One thread WRITE a value, while another thread READ, may cause half write problem, or code path may optimized by the compiler。I don't know if am i right? maybe here should add keyword volatile. maybe?

 

update version 1.54

- buffer2File fix. (was adding modified time field when it was not needed.)
- Added Linux glibc 2.17 version plugins (useful for SteamOS).

update version 1.53

- Fixed some preprocessor directives.

 

Hello.

Yes you can. Using the FileBuffer pointer parameter you can handle a buffer as a zip archive and extract from there to a buffer or to the file system.

See attached doc file.

 

Hi,

We are currently using your plugin in our project but an error occured when built for Android on ARM64 IL2CPP. Application can be launched but game never starts. The error is the following :

Unity : Unable to find zipw
Unity : DllNotFoundException: Unable to load DLL 'zipw': The specified module could not be found.

It works well when built for Android on ARMv7 IL2CPP though. We checked that plugins are assigned for the appropriate platforms. (see screenshot below). We are using Unity 2018.4.5f1.

Do you know where it could come from ?

Thanks.

EDIT: We've made changes on the lib/arm64-v8a/libzipw.so file to put only android available in ARM64 and it's now working. Changes look weird in file code though. (see new screenshots below). We never changed this file before.

 

Hi,
thank you, shortly after sending my last question, I found the soloution by myself. It works . But now I want to do the reverse way to compress a buffer into a zip archive without using the file system. There is a function "compressBuffer" but there is no parameter to specify the filename. And "buffer2File" needs a path to the file system. Is there a way to do this?

best regards, Meinolf

 

I have finished today the feature to create in memory zip files and decompress from there to memory or the file system.

It should be up in the store in a few days.

 

update version 1.55

- Added the ability to create In Memory zip archives and manipulate them.
- MacOS: removed the 32bit only bundle.
- Replaced the www functions with UnityWebRequest.
- Removed the watchOS plugins.
- Docs updated.

 

Hi!
I have an issue with lzip.gzip() method. I use it from UnityEditor on my PC.

I'm trying to gzip stream with 4 Texture2D files, sometimes it works, but sometimes - not. Depends on the map I put, but I can't definitely say what is the technical difference between them (the same BitDepth, the same TextureFormat and etc). I convert Texture2D to byte[] with the help of EncodeToPNG(), and if it doesn't like any of my maps the final gzip file will be doomed. It has uncompressed size and I can't read it properly: for example, I successfully read the first map, but the second failed. If I comment the lines of creating gzip, I will be able to read all the stream without difficulties.

My current solution is using EncodeToJPG() instead, but I don't like it very much.

Really appreciate any ideas about this case

 

Hello.

Sorry for the late reply but I was away for 3 days.

The issue here I imagine is that encoding to png makes the byte array un-compressible in terms that the final gzip is larger then the original data.

But please send me in a private message a sample texture and the code you are using so that we can work something out.

-------

Also try to use the lzip.unGzip2 function instead of lzip.unGzip.

 

update version 1.56

- tvOS has its own plugin folder now.
- iOS/tvOS plugins are provided by default as bitcode enabled. (non bitcode versions are still provided.)

update version 1.57

- tvOS plugin was accidentally not set as bitcode by default.

 

Thank you for the answer! I've sent email to elias_t@yahoo.com

 

decompress_File failed on IOS, Xcode11, Unity2018.4.9!

 

Hello.

It seems something went wrong with the downloaded zip file.
If you can send me the sample project using a personal message so I can check it.

Thank you.

 

This is sample scene "testZip", (error after update Xcode11)

 

Ok.

I will check with xcode 11 and get back to you.

 

Hello.

I have made various tests with Unity 2019.1 and Xcode 11.1 and all seems fine.

 

update version 1.58

- iOS: fixed some conflict issues with the Facebook SDK.

 

Hi,

the current version works very well. Are there plans to support more platforms like Switch, XBox and PS4? I would pay for an expanded version with pleasure again

 

Hello. Not for now. Although I am investigating the Switch option.

 

Hi!

I having one error with the new version of xCode and the new version of the library. Unity version is 2018.4.10. Here is the error:

duplicate symbol '_zipCloseFileInZipRaw64' in:

/Users/path/Libraries/libiPhone-lib.a(zip.o)
/Users/path/Libraries/ADL-Plugins/Plugins/iOS/libzipw.a(zip.o)

ld: 2 duplicate symbols for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

So, it seems that the symbol '_zipCloseFileInZipRaw64' exists in the 2 libraries? Anyone has encountered the same error?

Thanks!

Albert

 

Hello.

Although this is not happening on Unity 2019 I will make an update asap and send the plugins to you via pm.
Later I will update the asset store projects.

 

update version 1.59

- iOS/tvOS: fixed duplicate symbol issue with Unity2018.

 

update version 1.60

- fixed some C# issues with the compress_dir and compress_file_list functions
