Key: COMPRESS-7 (was: SANDBOX-170)
Project: Commons Compress (was: Commons Sandbox)
> Creating TAR archive of an 8 GB file causes IOException
> -------------------------------------------------------
>
> Key: COMPRESS-7
> URL: https://issues.apache.org/jira/browse/COMPRESS-7
> Project: Commons Compress
> Issue Type: Bug
> Environment: Win xp pro sp2; JDK 1.5.0_07
> Reporter: Sam Smith
>
> Yesterday I reported a bug with extraction of TAR archives:
> https://issues.apache.org/jira/browse/SANDBOX-168
> Today I found that when I tried to creat a TAR archive of a file that is
> exactly 8 GB, that is,
> (8L * 1024L * 1024L * 1024L) - 1
> that it failed with the following strange error:
> Exception in thread "main" java.io.IOException: request to write '32768'
> bytes exceeds size in header of '-1' bytes
> at
> org.apache.commons.compress.archivers.tar.TarOutputStream.write(TarOutputStream.java:341)
> at bb.io.StreamUtil.transfer(StreamUtil.java:312)
> at bb.io.StreamUtil.transfer(StreamUtil.java:290)
> at bb.io.TarUtil.writeFileData(TarUtil.java:404)
> at bb.io.TarUtil.archive(TarUtil.java:382)
> at bb.io.TarUtil.archive(TarUtil.java:334)
> at
> bb.io.TarUtil$Test.test_archive_extract_fileLengthLimit(TarUtil.java:610)
> at bb.io.TarUtil$Test.main(TarUtil.java:542)
> The code that I used to try and create the TAR archive was the same described
> in that previous bug report, so I will not repeat it here.
> I was doing this in an attempt to discern if the org.apache.commons.compress
> TAR code has any file size limits, since classic TAR is limited to 8 BG files
> but org.apache.commons.compress supports GNU TAR long path names, so maybe it
> has no file size limits either. (There appears to be no documentation about
> this in the TAR code.)
> What is strange is that the code first DID apparently succeed in TARing a 10
> GB file, albeit, when I tried to see if a third party piece of software
> (7-zip) would extract it, that program objected saying that it did not
> support the TAR format type encpuntered in the file.
> Since I need to use a file size limit that is consistent with other programs,
> I then tried to TAR a file of exactly 8 GB in size. This is when I
> encountered the above error.
