Problem with zip64 on native Xiaomi archiver utility #18

Open dmkl opened 1 year ago

dmkl commented 1 year ago

We are streaming lots of archives with zstream. It works very well except the native Xiaomi archiver utility, that fails to unzip a zip64 archive. The first idea was that this is a bug in that utility, but it handles zip64 archives from another streaming solution mod_zip with no issues.

Another hint that something might be wrong with zip64 format is that zipdetails mac/linux util fails to display zstreams zip64 details. Here is an example script and files.

Zstream.zip([
  Zstream.entry("test/10.txt", File.stream!("10.txt", [], 512), coder: Zstream.Coder.Stored)
])
|> Stream.into(File.stream!("/tmp/test.zip"))
|> Stream.run

Zstream.zip([
  Zstream.entry("test/10.txt", File.stream!("10.txt", [], 512), coder: Zstream.Coder.Stored)
], zip64: true)
|> Stream.into(File.stream!("/tmp/test_zip64.zip"))
|> Stream.run
$ zipdetails /tmp/test.zip

Please confirm if the mod_zip generated files are actually in zip64 format. From a quick look at the code, mod_zip only uses zip64 if the file size is > 4GB. If you have zip64 file encoded using the data descriptor method (stream) that works in Xiaomi, please upload it here, then it would be easier to debug the issue.

dmkl commented 1 year ago

Yes, we are talking about 4Gb+ files that mod_zip streams as zip64. I've attached smaller files just as an example, because the problem is reproducible with them both with the native Xiaomi-phones archiver utility and with zipdetails.

ananthakumaran commented 1 year ago

I meant, I want a file that works in Xiaomi, I am assuming the above one is not working in Xiaomi?

dmkl commented 1 year ago

Sorry for the confusion. All mod_zip files are working on Xiaomi, test.zip works on Xiaomi as well, test_zip64.zip doesn't work on Xiaomi.

Broken zstreams zip64 files (both under and over 4Gb) either do not unpack on Xiaomi or extract files with 0 bytes content like on the screenshot below.

ananthakumaran commented 1 year ago

All mod_zip files are working on Xiaomi, test.zip works on Xiaomi as well, test_zip64.zip doesn't work on Xiaomi.

I want a zip64 file (with data descriptor encoding) that works on Xiaomi. The test.zip is non zip64 file generated by zstream.

ananthakumaran commented 1 year ago

I built the mod_zip locally and modified it to use zip64 for all file sizes. Since it knows the file size, it is setting the correct size in the local header itself

This is not possible in zstream case, as it works on stream abstraction and doesn't know the file size. Full output below

Here are some more examples:

Working file from mod_zip https://dmkl.s3.eu-west-1.amazonaws.com/zip/4gb_mod_zip.zip (works on Xiaomi)

Broken file with the same content from zstream https://dmkl.s3.eu-west-1.amazonaws.com/zip/4gb_zstream.zip

Is there a way to extend zstream in the similar manner to fix the issue if we know file sizes upfront?

ananthakumaran commented 1 year ago

test_zip64_1.zip

test_zip64_2.zip

test_zip64_3.zip

could you check if any of the following variation works?

Is there a way to extend zstream in the similar manner to fix the issue if we know file sizes upfront?

if crc and size available, this is possible, but might require a bit of work on zstream side

dmkl commented 1 year ago

None of the three work on Xiaomi :\

dmkl commented 1 year ago

We have the CRC and the size for all files. It would be fantastic to support this case!

ananthakumaran commented 1 year ago

if CRC and file size are available, and the coder is Zstream.Coder.Stored, then yes, it should be possible to drop the data descriptor and put all the details in the local header itself. I will see if I can get something out this weekend

dmkl commented 1 year ago

Thanks a lot! Looking forward to it. Please let me know if I can help with anything.

ananthakumaran commented 1 year ago

could you try https://github.com/ananthakumaran/zstream/pull/19

dmkl commented 1 year ago

Archives > 4Gb are still broken on Xiaomi 😢 zipdetails shows this error:

▶ zipdetails ~/Desktop/4Gb.zip

Done

Here is a test archive https://take.ms/Z58ua

ananthakumaran commented 1 year ago

@dmkl I have pushed some changes which seem to remove the warnings messages I used to get on zipdetails. Can you give it another try. If it doesn't work, I need to find a way to run Xiaomi or something equivalent so I can test it.

dmkl commented 1 year ago

Thanks for another attempt! It didn't fix the issue, unfortunatelly 😕 All is the same. Here is a test archive. Please let me know if I can help with any other tests or info.

ananthakumaran commented 1 year ago

Working file from mod_zip https://dmkl.s3.eu-west-1.amazonaws.com/zip/4gb_mod_zip.zip (works on Xiaomi)

I checked this file, you can find the zipdetails output below. This is not a zip64 file. My guess is, Xiaomi doesn't support zip64 at all? As per zip spec, zip64 is really needed if size/offset used in the file exceeds the 32 bit range. I am guessing, in this case individual file size didn't exceed 32 bit range and mod_zip decided to not use zip64. Anyways, We need to verify if Xioami archive utility supports zip64 at all. Also, is this something I can download? I have android phone and can check it, but can't figure out how to get the utility. Google search doesn't return anything useful.

dmkl commented 1 year ago

I've done another test.

1) Created an archive on my mac with two 4.7Gb files, so the file size and the offset exceed 32 bit range. This file has no problem on Xiaomi and everything opens fine. It seems that the Xiaomi util supports zip64 (maybe still not in a streaming fashion?)

2) Created a similar archive with mod_zip and Xiaomi cannot handle it.

The fact that Xiaomi can handle mac's archive makes me think that it supports zip64. Wdyt?

Interesting, could you share the zipdetails -v of the first file?

Hi Anantha, do you have any further ideas on this topic?

ananthakumaran commented 1 year ago

I haven't looked at the issue since my last comment. I have been working on a few other things. The main issue is, I don't know how much time would be needed to figure out the root cause. I also don't have a way to reproduce it locally (and verify the fix), which makes it very time-consuming.
