Subject: RFR: 8374535: IOS uses different path for modules
Message-ID: <0F-nq_wAdWnm6JDFjnqQvvEeLt0qi3VUGzq29tElFDM=.580dbaeb-3458-4e0a-846d-7397b64ce18a@github.com>

I spent like 20 hours debugging this. I am shipping an app for iOS which uses Java. The exploded modules works fine. But when I tried to publish my app I got this error https://github.com/openjdk-mobile/ios-tools/issues/61

So I then built a module file, but was getting this error that it couldn't find the module file. I read the code and found on iOS it looks at the `JAVA_HOME/Documents/lib/module` sure whatever I did that. And the JVM still failed to initialize. After debugging for what felt like forever

I found that https://github.com/openjdk/mobile/blob/205325c987df20d8d72372f45910137d61da0850/src/hotspot/share/classfile/classLoader.cpp#L1418-L1420 is hard code to search `Java_HOME/lib` which is what Default Java uses.

So I removed the custom pathing check for the module file for iOS which is seen in this PR diff and it worked ? . I don't know why that `ifndef` was added, but I don't think it should be there. I think we should use the defaults for Java, as Java's JVM initialization errors aren't that helpful, so we shouldn't be doing magic for iOS. If I want my modules in `Documents` I will set my `JAVA_HOME` myself. Anyways thought I would make a PR to help out this cause ?. Also I am SO HAPPY my java app works now on iOS. Thank you guys so much <3.

**TLDR** Jimage module file exists check for iOS is different then Jimage module path we read from.

Thanks for this PR. The location of the (exploded) modules is an issue indeed, and I'm unsure about the best approach here. I'll check my local notes to see why I added the ifndef regarding `Documents` being in the path.

I created https://bugs.openjdk.org/browse/JDK-8374535 for this. The PR should have the same name as the issue title.

Once OCA is processed (give that a week), this can be integrated.

This PR is related to non-exploaded modules, not exploaded modules

@johanvos the title is updated

@KolbyML I hate to say this, but the title needs to be prefixed by the bug id, so it has to be this:
8374535: IOS uses different path for modules
(see examples at https://github.com/openjdk/jdk/pulls)

This is needed for the skara tools, which will also automatically update the info in the JBS entry (https://bugs.openjdk.org/browse/JDK-8374535) with this. It's a bit of administration, but it allows for much easier tracking later.

Meanwhile, I looked into the PR and I agree with the change, so once Skara recognizes this as a valid PR, I can immediately approve.

I don't know how but Kotlin calls OperatingSystem.IOS, adding iOS as an OperatingSystem fixed my problems, it had something to do with Kotlin's logging library if I remember correctly during initialization it calls something with OperatingSystem.IOS then it panics because IOS isn't an option in the OperatingSystem Class

All good now.

Can you create a JBS issue for this? In order for Skara to deal with this PR, it needs to be linked to an issue in JBS (project JDK, OS iOS).
https://bugs.openjdk.org/issues/?jql=project%20%3D%20%2210100%22%20AND%20OS%20%3D%20iOS
Let me know if you need help with this.

Can you change the title of this PR into 
8374522: Mobile: Add iOS as a platform in OperatingSystem.java

src/java.base/share/classes/jdk/internal/util/OperatingSystem.java line 106:

> 104:     @ForceInline
> 105:     public static boolean isMacOS() {
> 106:         // Treat iOS as macOS for compatibility with existing libraries unless specific IOS checks exist

I don't think this is needed once the isIOS() call is added? (which is added in this PR)

My contributor agreement is under review right now

I run this jar on iOS https://github.com/Suwayomi/Suwayomi-Server and here is my iOS project https://github.com/KolbyML/Mangatan/tree/master/bin/mangatan_ios

Suwayomi-Server.jar initalizes Kotlin's logger which calls OperatingSystem.iOS, but then I got an error because the modules or static libs I built from openjdk/mobile OperatingSystem didn't have iOS as a member, when I added the member the panic went away

Sure I will submit an issue there

I submitted a bug report

Hi @johanvos it appears that I can't login because I don't have an account, and it looks like getting an account is an invite thing, so I don't think I am able to make an issue, although I want to!

If you could help me make an account that would be greatly appreciated!

@KolbyML  unfortunately, I can't create/modify accounts on JBS. If you don't have an account, you can still file an issue at https://bugs.java.com/bugdatabase/
It will then manually be triaged, and after that, it should be auto-assigned to me (hopefully).
While the triage can take a few days, it would help adding a code snippet here on how this would be intended to use.

@KolbyML fyi, I pinged someone at Oracle for getting the status of your OCA verification, but I didn't hear back yet. I hope it is fixed soon. Sorry about the delay this is causing.

Also, it looks really odd.  Why isn't it something like:

return current() == MACOS || current() == IOS;

or 

return PlatformProps.TARGET_OS_IS_MACOS || PlatformProps.TARGET_OS_IS_IOS;

?

Hi all,

this is an _automatically_ generated pull request to notify you that there is 1 commit from the branch `jdk:master`that can **not** be merged into the branch `master`:

The following file contains merge conflicts:

- make/autoconf/libraries.m4

All Committers in this [project](https://openjdk.org/census#mobile) have access to my [personal fork](https://github.com/openjdk-bots/mobile) and can therefore help resolve these merge conflicts (you may want to coordinate who should do this).
The following paragraphs will give an example on how to solve these merge conflicts and push the resulting merge commit to this pull request.
The below commands should be run in a local clone of your [personal fork](https://wiki.openjdk.org/display/skara#Skara-Personalforks) of the [openjdk/mobile](https://github.com/openjdk/mobile) repository.


# Ensure target branch is up to date
$ git checkout master
$ git pull https://github.com/openjdk/mobile.git master

# Fetch and checkout the branch for this pull request
$ git fetch https://github.com/openjdk-bots/mobile.git +12:openjdk-bot-12
$ git checkout openjdk-bot-12

# Merge the target branch
$ git merge master


When you have resolved the conflicts resulting from the `git merge` command above, run the following commands to create a merge commit:


$ git add paths/to/files/with/conflicts
$ git commit -m 'Merge jdk:master'



When you have created the merge commit, run the following command to push the merge commit to this pull request:


$ git push https://github.com/openjdk-bots/mobile.git openjdk-bot-12:12


_Note_: if you are using SSH to push commits to GitHub, then change the URL in the above `git push` command accordingly.

Thanks,
J. Duke
