created issue #1

Jan 15, 2019 11:48AM

Trying to open large project, scanning files to index never ends and after running for a while, idea log shows out of memory error every 2 seconds.

There was also svn error, that said that my home folder was not in svn. Not sure if it tries to index my whole home folder now..

Everything works fast if I use experimental use active configuration only setting, but then I cant see my cpp files :(

Yes, kapt incremental compilation support is available since 1.3.40-dev-795
Is there already some plan to add support to Room?

Create integration test for Room that uses gradle test kit.

Useful for testing Room incremental annotation processing in Gradle.

Also consolidated some of the path definitions in various build.gradle
into methods in buildSrc/SupportConfig.

commit a68222dc929ae5e2a3445f9df69a63636854852e
Author: Hung Nguyen <hungnv@google.com>
Date: Fri Mar 29 11:39:50 2019

Prepare Room for incremental annotation processing.

In Java projects, with non-incremental annotation processing, the inputs
to an annotation processor includes only Java source files.

With incremental annotation processing, however, the inputs may include
both Java source files and class files (to avoid recompiling source
files that haven't changed).

Therefore, all Room annotations need to have retention policy CLASS or
RUNTIME (not SOURCE), so that Room can find the elements annotated with
those annotations from class files. This requirement is also stated at

https://docs.gradle.org/current/userguide/java_plugin.html#sec:incremental_annotation_processing.

Branch: androidx-master-dev

commit 6f65f09de487c04fa40b4734d88b92a79fe2c545
Author: Hung Nguyen <hungnv@google.com>
Date: Wed May 08 15:49:58 2019

Make Room an isolating incremental annotation processor.

This CL introduces an annotation processor option called
`room.incremental`
which the user can set to try out incremental annotation processing with
Room. It is currently off by default.

The user can pass the option through the Android Gradle plugin's DSL,
for example:

android {
defaultConfig
javaCompileOptions {
annotationProcessorOptions {
argument 'room.incremental', 'true'
}
}
}
}

Caveat: There is a JDK bug

https://bugs.openjdk.java.net/browse/JDK-8007720 that prevents Room from
being incremental (details are discussed in the code comment).
Therefore, if the JDK version being used does not already have this fix,
Room cannot be incremental and we will print out a warning to ask the
user to use a JDK version having the fix.

Note that Room currently does not track the annotation processor option
`room.schemaLocation` properly as an @OutputDirectory, and this could
impact build correctness. However, this issue impacts both
non-incremental and incremental builds, and it already existed before,
so we will fix it separately (tracked at

bug 132245929

).

Additionally, Room is currently not using the
javax.annotation.processing.Filer API to let Gradle know the originating
element of a generated schema file, so the schema files may not get
deleted properly when certain source files are deleted (tracked at bug
134472065).

Room 2.2.0 will be an incremental annotation processing when enabled via the option 'room.incremental = true'

ma...@gmail.com <ma...@gmail.com> #12Jan 16, 2019 09:17PM

When will be some alpha or at least snapshot build with this support, please?

ma...@gmail.com <ma...@gmail.com> #13Jan 16, 2019 09:28PM

in a couple of weeks, we should have it.

an...@supercell.com <an...@supercell.com> #14Jan 17, 2019 07:03AM

I updated to 2.2.0 stable release and added the option "room.incremental = true" to my gradle properties.
But I am still seeing this warning:
w: [kapt] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: androidx.room.RoomProcessor (DYNAMIC).

ex...@gmail.com <ex...@gmail.com> #15Jan 17, 2019 04:05PM

Sorry about my last comment. I just saw I configured it wrong. It is not supposed to be se tin the gradle.properties, but in the annotationProcessorOptions.

android {
...
defaultConfig {
...
javaCompileOptions {
annotationProcessorOptions {
arguments = [
"room.schemaLocation":"$projectDir/schemas".toString(),

Is it switched on by default in 2.2.5? Because I still got the message got a warning from kapt

[WARN] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: androidx.room.RoomProcessor (DYNAMIC).

Solved to adding "room.incremental"="true" in the annotation params.

Oops, spoke too soon. First appears in the release notes for 2.3.0:

KNOWN ISSUE: Note that incremental Room is currently broken in some cases (Issue 159501719), so we may need to revert this change or send out a patch to at least provide workarounds to users. https://issuetracker.google.com//159501719#comment18 lists the possible fixes.

Seems related to this issue

https://issuetracker.google.com/123131649

Somehow the home directory is being added as a source root:

<component name="NewModuleRootManager" LANGUAGE_LEVEL="JDK_1_7">
<output url="file://$MODULE_DIR$/build/intermediates/javac/debug/compileDebugJavaWithJavac/classes" />
<output-test url="file://$MODULE_DIR$/build/intermediates/javac/debugUnitTest/compileDebugUnitTestJavaWithJavac/classes" />
<exclude-output />
<content url="file://$USER_HOME$">
<sourceFolder url="file://$USER_HOME$" isTestSource="false" /> <------ Bad
....

Which forces the entire contents of the user's home directory to be scanned and indexed. We are using C++ libraries outside of the project's root - namely prebuilt Conan packages located in ~/.conan. Is there any workaround?

qu...@gmail.com <qu...@gmail.com> #25Jan 29, 2019 07:00AM

A workaround that I have found is that when I see that is indexing "C:\" in the "Project Source Files" pane. I go to the app.iml file and remove the content tag that has the "C:\" and save the file. That does that it stops the indexation of "C:\" and continue with the correct source directories.

But that makes that when the indexation "ends", it gets "stuck" (actually looks like is loading something, but never ends), in order to solve that I go to the Gradle pane and refresh the gradle project. When it is finally done, the indexing also ends and Android Studio allows me to build the project.

Marked as fixed.

ma...@gmail.com <ma...@gmail.com> #26Feb 6, 2019 10:13PM

This particular issue is confirmed as fixed in 3.3.1. The scanning and indexing is still an order of magnitude slower than 3.2.1 (as is Android Studio overall), but at least now it completes in minutes vs. hours and doesn't crash or run out of memory anymore as per this ticket.

ar...@google.com <ar...@google.com> #27Feb 6, 2019 11:22PM

Thanks for verifying!
Can you provide more context around the scanning and indexing slowness you observed with 3.3.1 compared to 3.2.1?
Is it the same as

https://issuetracker.google.com/issues/121340427 or something else?
Thanks!

ro...@gmail.com <ro...@gmail.com> #28Apr 30, 2019 02:56PM

Although the bug is fixed, I still experiment the same problem in Android Studio 3.2.2 and 3.4.

When opening a project with a large amount of .h files (webrtc library), It takes around 10 mins in the indexing phase (long time but ok). The problem comes in the Building Symbols stage, it eats all the RAM avaiable and ends with a Low memory warning that makes the IDE unusable.
You can see in the attached screenshot where I configured the IDE to use 8Gb of RAM. If you increase the value it doesn't solve anything, it just does not stop consiming RAM until it hits the limit, no matter how high it is.

3.2 works ""ok"" (at least it doesn't freeze, but no code completion, syntax highlighting... )

Is there any workaround that could mitigate the issue?

Hi, can you give us some idea about the scale of the number of .h files in your library?
And if it's open source, where we can try to repro it ourselves, that would be even better.

[Deleted User] <[Deleted User]> #30May 2, 2019 11:37PM

This bug is still showing in 3.4......

comment #29

Thanks for answering!

Our project has around 60.000 .h/.hpp files.
Unfortunately our project is not open source, however, our biggest dependency is webrtc which is.

I would say that if you create a project that depends on webrtc, you will see the same problem.

tg...@google.com <tg...@google.com> #32May 3, 2019 07:18PM

Hi, I tried downloading the WebRTC source code following instructions from

https://webrtc.org/native-code/android/. There seems to be no CMakeLists.txt in the project and there are ~2300 headers in it. Do you create custom CMakeLists in order to include WebRTC as a dependency for your project?

Also, do you by any chance use Android Studio to open the generated gradle file in step

ho...@gmail.com <ho...@gmail.com> #33Jun 5, 2019 11:07PM

Hello, I am experiencing the same problem on 3.4. My project has around 2,000 .h, .c, and .cpp files. They are located across many different paths on my hard drive. Is there any progress on this issue? Thank you.
