[exonerator/release] Improve logging of database importer.
by karsten＠torproject.org 13 Apr '20

commit 54ad288276bd2313ff81a71406f027801e51fa55 Author: Karsten Loesing <karsten.loesing(a)gmx.net> Date: Sun Mar 15 14:31:10 2020 +0100 Improve logging of database importer. This patch focuses on providing more context in log messages and unify the use of log levels. It also adds counters and timestamps as far as they are being used in log messages. And in very few cases it contains minor changes like using try-with-resource when we're touching that code anyway. But most other refactorings are left as future work. Fixes the first part of #24542. The second part will be to improve logging of the web server parts. --- CHANGELOG.md | 3 + .../exonerator/ExoneraTorDatabaseImporter.java | 239 ++++++++++++++++----- 2 files changed, 186 insertions(+), 56 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 9c87922..ca10ec2 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -1,5 +1,8 @@ # Changes in version 4.?.? - 2020-0?-?? + * Minor changes + - Improve logging of the database importer. + # Changes in version 4.3.0 - 2020-01-15 diff --git a/src/main/java/org/torproject/metrics/exonerator/ExoneraTorDatabaseImporter.java b/src/main/java/org/torproject/metrics/exonerator/ExoneraTorDatabaseImporter.java index 3dbb119..53e58f7 100644 --- a/src/main/java/org/torproject/metrics/exonerator/ExoneraTorDatabaseImporter.java +++ b/src/main/java/org/torproject/metrics/exonerator/ExoneraTorDatabaseImporter.java @@ -11,6 +11,7 @@ import org.torproject.descriptor.ExitList; import org.torproject.descriptor.ExitList.Entry; import org.torproject.descriptor.NetworkStatusEntry; import org.torproject.descriptor.RelayNetworkStatusConsensus; +import org.torproject.descriptor.UnparseableDescriptor; import org.apache.commons.codec.DecoderException; import org.apache.commons.codec.binary.Base64; @@ -25,7 +26,9 @@ import java.io.File; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; +import java.io.LineNumberReader; import java.nio.file.Files; +import java.nio.file.Path; import java.nio.file.Paths; import java.sql.CallableStatement; import java.sql.Connection; @@ -49,46 +52,65 @@ public class ExoneraTorDatabaseImporter { /** Main function controlling the parsing process. */ public static void main(String[] args) { + logger.info("Starting ExoneraTor database importer."); readConfiguration(); openDatabaseConnection(); prepareDatabaseStatements(); createLockFile(); + logger.info("Fetching descriptors from CollecTor."); fetchDescriptors(); + logger.info("Importing descriptors into the database."); readImportHistoryToMemory(); parseDescriptors(); writeImportHistoryToDisk(); closeDatabaseConnection(); deleteLockFile(); + logger.info("Terminating ExoneraTor database importer."); } - /* JDBC string of the ExoneraTor database. */ + /* JDBC string of the ExoneraTor database.
