commit bdde5a1a970ddc9007b28de4aa29d60ffa588f08
Author: Yigit Boyar <yboyar@google.com>
Date:   Thu Apr 16 16:47:05 2020

    Re-factor how errors are dismissed when query is re-written
   
    This CL changes how we handle errors/warnings if query is
    re-written.
    There was a bug in expandProjection where we would report warnings
    for things that Room already fixes automatically (b/140759491).
    The solution to that problem (I7659002e5e0d1ef60fc1af2a625c0c36da0664d8)
    solved it by deferring validating of columns until after re-write
    decision is made. Unfortunately, this required changing PojoRowAdapter
    to have a dummy mapping until it is validating, make it hard to use
    as it does have a non-null mapping which is not useful.
   
    This CL partially reverts that change and instead rely on the log
    deferring logic we have in Context. This way, we don't need to break
    the stability of PojoRowAdapter while still having the ability to
    drop warnings that room fixes. This will also play nicer when we
    have different query re-writing options that can use more information
    about the query results.

    Bug: 140759491
    Test: existing tests pass

I'm having the same issue. Canary 8 / alpha8 with one app module.

My stack trace also mentions an IllegalArgumentException at the bottom - java.lang.IllegalArgumentException: Mandatory Manifest-Version attribute missing

Just an update, I tested my project with new release and problem still remains:

Android Studio 3.0 Canary 9
Build #AI-171.4220116, built on July 27, 2017
JRE: 1.8.0_152-release-884-b01 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Mac OS X 10.12.6

back to Canary 4 😉

Alex, can you have a look ?

What's happening is that the signing step of the APK building pipeline is presented with a pre-existing META-INF/MANIFEST.MF which, for some reason, does not contain the Manifest-Version attribute in its main section, making it an illegal/malformed manifest. Please assign to an owner of the APK building pipeline to investigate further.

Hung, could you have a look. thx

@#5 (Eliezer Graber): Is it possible that you cook up a small project and share with us?

I'm sorry, but I haven't been able to repro it.

I am not sure if this error is related to previous one, but after updating to recent Android Studio 3.0 Beta 1, I get this new error message and I am still unable to update my Android Studio to any new builds after Canary 4:

Android Studio 3.0 Beta 1
Build #AI-171.4243858, built on August 4, 2017
JRE: 1.8.0_152-release-915-b01 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Mac OS X 10.12.6

@#13: It's a different error. Please see our known issues at the top of this page: https://developer.android.com/studio/build/gradle-plugin-3-0-0.html

Yes you where right, I fixed this issue by cleaning and adding new Android support libraries and also adding google as project repository. but after all previous issue (java.io.IOException: Failed to generate v1 signature) back again.

Can you reproduce this issue consistently? It would be great if you could reproduce it without changing branches (e.g., by looking at the diff between the two branches and figuring out the smallest change that would trigger the issue).

After more investigation using "gradle assemble --stacktrace" I found that the issue is with zip process:

    Error:org.gradle.tooling.BuildException: Failed to generate v1 signature
    Error:java.io.IOException: Failed to generate v1 signature
    Error:com.android.apksig.apk.ApkFormatException: Unsupported character 0x0d in ZIP entry name "assets/.../Icon?"

There was a file named "Icon?" in my project which causes the crash.
I deleted the file and now everything is working fine.

This issue showed up in all versions after Android Studio Canary 4!
You can close this issue if there is nothing to do for fixing it!

3.0 Canary 4 is about the time we added that "Unsupported character" check, so that's why it happens from that version forward.

@Alex, it looks like we should not fail on the "?" character right? (Or maybe it is some encoded character that we fail to convert to a char type.) Could you look at the "CR, LF, and NUL are not permitted in ZIP entry names" change in V1SchemeSigner and confirm whether there is a bug in that code?

I'm confused. Why do you think that it is the '?' character which is to blame? The error message in comment #17 explicitly calls out the 0x0d character, not the '?' character.

From comment #17, it's true that the exception is thrown for the 0x0d character; but also from the same comment, if the reporter removes the file named "Icon?" then there is no exception. Therefore, I was wondering if if there could be anything problematic with the V1SchemeSigner.checkEntryNameValid method (I know it's unlikely, but it's worth checking).

@Mohsen Mirhoseini: Could you show us the full path of that "Icon?" file? Is there any irregular character in that file? And where do you think the '?' character come from? My best guess is that the '?' character is actually the '\0' character but the system has to show it in the form of a '?' character.

It is not `?` character, I think it is `Icon` end with two \r (according to my .gitignore_global -> Icon<CR><CR>), which is a mac file system icon you or other applications can assign to folders and according to this link, it is very easy to make one!
http://www.hongkiat.com/blog/customize-mac-folder-icon/

It is hidden and you should press command + shift + . to make it visible.

I see, in that case I'm afraid you will have to remove the file because we currently don't support file names with these characters during signing. (@Alex, please correct me if I'm wrong.)

I'm not sure how we can work around this issue, looks like I will have to close this as impossible to fix.

Thanks for your report and the prompt response!

I got this again when I disconnected the device I was deploying to while the app was building. Subsequent builds failed with the same error until I did a clean build.

Correct. JAR signatures (aka v1 APK signatures) do not support file names containing CR characters. The reason is that file names are listed in META/MANIFEST.MF and META-INF/*.SF files without any escaping, yet CR character is treated as a line delimiter in these files.

@Eliezer Graber: Are you also on a Mac and your assets contain "Icon\r" files? (If not, please consider filing another bug with us for better tracking.) Can you reproduce the issue consistently?

Good to know, as I mentioned I have solved my project issue by removing that file, but it could be a warning or an error with more details during build time from Android Studio in later versions.

Thanks

Please add to the list of known issues for 3.0.

I have the same error, tried a few things including removing every instance of "\n" in the project, I'm on Windows so I don't have any "Icon\r" file. If anyone knows how to fix this please share! Going back to v2 on this project in the meanwhile.

@João Sardinha: For better tracking, please leave your comments at Issue 67394465 (which reports the same exception but is not related to the use of "Icon\r" files). Also attach a sample project if you can. Thanks!
