From d54e3a36492aa00a36523e964c453762f062bd89 Mon Sep 17 00:00:00 2001 From: Dave Roussel Date: Fri, 8 Jun 2018 11:44:11 +0100 Subject: [PATCH 1/5] Fix for #141 At the end of LargeText.writeLogTo() the size size is returned back as a long, but the calculation is done with int math, not long. So we get a problem for large files. This fix enables files longer than Integer.MAX_VALUE to be handled. Unfortunately the only way to test this is by writing out a file that is larger than Integer.MAX_VALUE. This test takes 24 seconds to run on my MacBookPro 15" (2015), which has a very fast SSD. To test in any other way would mean much larger changes to LargeFile, just for test purposes. --- .../stapler/framework/io/LargeText.java | 2 +- .../stapler/framework/io/LargeTextTest.java | 57 +++++++++++++++++-- 2 files changed, 54 insertions(+), 5 deletions(-) diff --git a/core/src/main/java/org/kohsuke/stapler/framework/io/LargeText.java b/core/src/main/java/org/kohsuke/stapler/framework/io/LargeText.java index b91fa1a439..b83af09459 100644 --- a/core/src/main/java/org/kohsuke/stapler/framework/io/LargeText.java +++ b/core/src/main/java/org/kohsuke/stapler/framework/io/LargeText.java @@ -234,7 +234,7 @@ public long writeLogTo(long start, OutputStream out) throws IOException { f.close();
