-------------------------------------
Summary: Buffer not read first time for entries with STORED
compression method
Key: COMPRESS-268
URL: https://issues.apache.org/jira/browse/COMPRESS-268
Project: Commons Compress
Issue Type: Bug
Components: Archivers
Environment: * Fedora 20 x64
* Java 1.7.0_51 x64
* archive created with Nautilus' context menu
Reporter: Radu Almășan
Trying to extract a ZIP archive that contains entries with {{STORED}}
compression method, the {{ZipArchiveInputStream.readStored(byte[], int, int)}}
method is called. At this point, because the {{buf}} array has not had a chance
to be populated with values from the underlying input stream and because
there's no condition to detect this, the resulting content is prefixed with the
buffer's length (512) of 0 bytes.
I've found that chancing:
bq. if (buf.position() >= buf.limit()) {
with
bq. if (buf.position() >= buf.limit() || current.bytesReadFromStream == 0) {
solves the issue.
