Revision 52733b44984b67584121efb6730a9020cab3a67c authored by Maysam Yabandeh on 05 November 2019, 00:22:26 UTC, committed by Facebook Github Bot on 05 November 2019, 00:23:57 UTC
Summary: MaxCatchupWithNewSnapshot tests that the snapshot sequence number will be larger than the max sequence number when the snapshot was taken. However since the test does not have access to the max sequence number when the snapshot was taken, it uses max sequence number after that, which could have advanced the snapshot by then, thus making the test flaky. The fix is to compare with max sequence number before the snapshot was taken, which is a lower bound for the value when the snapshot was taken.

RELEASE.md
## Cross-building
RocksDB can be built as a single self contained cross-platform JAR. The cross-platform jar can be usd on any 64-bit OSX system, 32-bit Linux system, or 64-bit Linux system.
Building a cross-platform JAR requires:
* [Vagrant](https://www.vagrantup.com/)
* [Virtualbox](https://www.virtualbox.org/)
* A Mac OSX machine that can compile RocksDB.
* Java 7 set as JAVA_HOME.
Once you have these items, run this make command from RocksDB's root source directory:
make jclean clean rocksdbjavastaticrelease
This command will build RocksDB natively on OSX, and will then spin up two Vagrant Virtualbox Ubuntu images to build RocksDB for both 32-bit and 64-bit Linux.
You can find all native binaries and JARs in the java/target directory upon completion:
librocksdbjni-linux32.so
librocksdbjni-linux64.so
librocksdbjni-osx.jnilib
rocksdbjni-3.5.0-javadoc.jar
rocksdbjni-3.5.0-linux32.jar
rocksdbjni-3.5.0-linux64.jar
rocksdbjni-3.5.0-osx.jar
rocksdbjni-3.5.0-sources.jar
rocksdbjni-3.5.0.jar
## Maven publication
Set ~/.m2/settings.xml to contain:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

<server>
<id>sonatype-nexus-staging</id>
<username>your-sonatype-jira-username</username>
<password>your-sonatype-jira-password</password>
</server>
</servers>
</settings>
From RocksDB's root directory, first build the Java static JARs:
make jclean clean rocksdbjavastaticpublish
This command will [stage the JAR artifacts on the Sonatype staging repository](http://central.sonatype.org/pages/manual-staging-bundle-creation-and-deployment.html). To release the staged artifacts.
1. Go to [https://oss.sonatype.org/#stagingRepositories](https://oss.sonatype.org/#stagingRepositories) and search for "rocksdb" in the upper right hand search box.
2. Select the rocksdb staging repository, and inspect its contents.
3. If all is well, follow [these steps](https://oss.sonatype.org/#stagingRepositories) to close the repository and release it.
After the release has occurred, the artifacts will be synced to Maven central within 24-48 hours.
