I think this also fixes #4131
I don't suppose anybody has published a build with this PR in it somewhere? We really need this in order to use Jib and are having trouble pinning commons-compress in our Gradle build.
@bjornbugge Thanks so much for this fix! It appears that the test jobs are failing with the following error:
Task :jib-core:checkstyleTest FAILED
Build cache key for task ':jib-core:checkstyleTest' is 1e2bdbced948a9c01563c97b77fe87b3
Task ':jib-core:checkstyleTest' is not up-to-date because:

Removing the extra space in the import statements in ReproducibleLayerBuilderTest
should hopefully help resolve this.

@mpeddada1 Thanks for taking a look at this. I've fixed the three tests that failed -- I thought I'd run the entire test suite locally, but clearly I had forgot :P (I guess I was in a hurry to make a local version of jib that we can use in our internal tooling)
Looks like the format check is failing

Thanks for the observation @diegomarquezp! @bjornbugge try running ./gradlew googleJavaFormat
to address the google formatting issues.
Additionally, to @chanseokoh's suggestion in https://github.com/GoogleContainerTools/jib/pull/4142#discussion_r1469684533, we haven't heard back from you on this so to reiterate - We learned that clearing the PAX header isn't sufficient and since the mtime
represent the modification time of the file, it would make more sense for it to be set to whatever value Jib sets it to. So if we set the modification time (using setModTime()
) to the default value, we set the pax header to the same value and if we use a user configured value then we just set the header to that value. Let us know if you have any questions after trying it out!
Could someone review this, please? Having reproducible builds again after 3+ months would be nice.
@izogfif it has been reviewed. It's waiting on the PR author.
@chanseokoh I see, this "Review required" message at the bottom of this issue page on GitHub made me misunderstand what's happening.
Previously in this comment you wrote:
167 is the user-configured value. Just set both the PAX headers and setModTime() to the same timestamp. For the (Jib-created) directiories, it is not customizable and always set to epoch+1.
To recap, just set the same value as Jib does now.
Where "167" is the number of line in ReproducibleLayerBuilder.kt
file which I was unable to find. If you were actually talking about file jib-core/src/main/java/com/google/cloud/tools/jib/image/ReproducibleLayerBuilder.java
, then do I understand you correctly that we need to:
add
of com.google.cloud.tools.jib.image.ReproducibleLayerBuilder.UniqueTarArchiveEntries
class and take tarArchiveEntry.getModTime().toInstant()
from there;build
of com.google.cloud.tools.jib.image.ReproducibleLayerBuilder
class and take layerEntry.getModificationTime()
from there;and pass this value into method clearTimeHeaders
. This will change this method from this:
private static void clearTimeHeaders(TarArchiveEntry entry) {
entry.setModTime(FileEntriesLayer.DEFAULT_MODIFICATION_TIME.toEpochMilli());
entry.addPaxHeader("mtime", "1");
entry.addPaxHeader("atime", "1");
entry.addPaxHeader("ctime", "1");
entry.addPaxHeader("LIBARCHIVE.creationtime", "1");
}
to this:
private static void clearTimeHeaders(TarArchiveEntry entry, Instant modTime) {
entry.setModTime(modTime.toEpochMilli());
// PAX headers use <seconds>.<nanoseconds> format
String headerTime = Long.toString(modTime.getEpochSecond());
final long nanos = modTime.getNano();
if (nanos > 0) {
headerTime += "." + nanos;
}
entry.addPaxHeader("mtime", headerTime);
entry.addPaxHeader("atime", headerTime);
entry.addPaxHeader("ctime", headerTime);
entry.addPaxHeader("LIBARCHIVE.creationtime", headerTime);
}
? This way:
FileEntry
.clearTimeHeaders
propagates this modification time to TarArchiveEntry
and corresponding PAX headers.@izogfif I cannot confirm the correctness of the implementation details of yours, but you got the right idea.
@chanseokoh I've made some changes and created a pull request with one extra commit. Please take a look here.
This PR is obsolete in favor of #4204.
Closing in favor of #4204. Thanks for getting us started with this fix!
Thanks for taking this over for me, @izogfif. Looking forward to a new release with this included :)
Fixes #4141 🛠️
