(was: Could FileUtils.copyFile not be flushed and synced when comparing file sizes?) > Should FileUtils.copyFile be flushed and synced before comparing file sizes? > ---------------------------------------------------------------------------- > > Key: IO-544 > URL: https://issues.apache.org/jira/browse/IO-544 > Project: Commons IO > Issue Type: Bug > Components: Utilities > Affects Versions: 2.5 > Environment: Win Server 2008, x86 > Reporter: Sean Poulter > > I've been struggling to troubleshoot intermittent {{IOExceptions}} thrown from {{FileUtils.doCopyFile}} when copying 2-4KB files from a local temporary file to a network drive. Despite the error, the file appears on the network drive when I check. Should the output channel/buffer be forced/flushed before closing, and synchronized before comparing the file lengths? It's a rather intermittent issue on a relatively high throughput PC so I'd expect there to be more IO latency than normal. > I found myself referencing: > * [The source code for FileUtils v2.5|https://commons.apache.org/proper/commons-io/javadocs/api-2.5/src-html/org/apache/commons/io/FileUtils.html] > * [FileChannel#force(boolean)|https://docs.oracle.com/javase/8/docs/api/java/nio/channels/FileChannel.html#force-boolean-] > * [IO-443 - FileUtils.copyFile methods throw an unnecessary "Failed to copy full contents from" exception|https://issues.apache.org/jira/browse/IO-443] > Thanks, > Sean -- This message was sent by Atlassian JIRA (v6.4.14#64029)
