From a4feeb01945e039b39a246f96a1a91b0e4836f01 Mon Sep 17 00:00:00 2001 From: Matthias Sohn Date: Sat, 28 Jan 2017 15:06:15 +0100 Subject: [PATCH] Don't rely on default locale when using toUpperCase() and toLowerCase() Otherwise these methods may produce unexpected results if used for strings that are intended to be interpreted locale independently. Examples are programming language identifiers, protocol keys, and HTML tags. For instance, "TITLE".toLowerCase() in a Turkish locale returns "t\u0131tle", where '\u0131' is the LATIN SMALL LETTER DOTLESS I character. See https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#toLowerCase-- http://blog.thetaphi.de/2012/07/default-locales-default-charsets-and.html Bug: 511238 Change-Id: Id8d8f37d84d62239c918b81f8d883ed798d87656 Signed-off-by: Matthias Sohn --- .../src/org/eclipse/jgit/lfs/server/s3/SignerV4.java | 6 ++++-- .../tst/org/eclipse/jgit/lfs/lib/LongObjectIdTest.java | 3 ++- .../src/org/eclipse/jgit/lfs/LfsPointer.java | 3 ++- org.eclipse.jgit.pgm/src/org/eclipse/jgit/pgm/Log.java | 5 +++-- org.eclipse.jgit.pgm/src/org/eclipse/jgit/pgm/Main.java | 4 +++- .../tst/org/eclipse/jgit/lib/ObjectIdTest.java | 4 +++- .../tst/org/eclipse/jgit/transport/WalkEncryptionTest.java | 5 +++-- .../src/org/eclipse/jgit/api/MergeCommand.java | 3 ++- .../eclipse/jgit/internal/storage/file/FileRepository.java | 3 ++- org.eclipse.jgit/src/org/eclipse/jgit/lib/Config.java | 3 ++- .../src/org/eclipse/jgit/patch/FormatError.java | 4 +++- .../src/org/eclipse/jgit/revwalk/FooterKey.java | 4 +++- .../src/org/eclipse/jgit/submodule/SubmoduleWalk.java | 4 +++- .../src/org/eclipse/jgit/transport/HttpAuthMethod.java | 6 ++++-- org.eclipse.jgit/src/org/eclipse/jgit/transport/NetRC.java | 3 ++- .../src/org/eclipse/jgit/transport/TransportGitSsh.java | 6 ++++-- .../src/org/eclipse/jgit/transport/WalkEncryption.java | 7 ++++--- org.eclipse.jgit/src/org/eclipse/jgit/util/FileUtils.java | 4 +++- 18 files changed, 52 insertions(+), 25 deletions(-) diff --git a/org.eclipse.jgit.lfs.server/src/org/eclipse/jgit/lfs/server/s3/SignerV4.java b/org.eclipse.jgit.lfs.server/src/org/eclipse/jgit/lfs/server/s3/SignerV4.java index f95b605c8..4149484c8 100644 --- a/org.eclipse.jgit.lfs.server/src/org/eclipse/jgit/lfs/server/s3/SignerV4.java +++ b/org.eclipse.jgit.lfs.server/src/org/eclipse/jgit/lfs/server/s3/SignerV4.java @@ -57,6 +57,7 @@ import java.util.Collections;
