Knut Anders Hatlen commented on DERBY-2839:
-------------------------------------------
Re 2)
GNU tar uses a (non-standard) format to store file names longer than 100
characters. For instance, using Solaris tar to extract the src-tar
distribution, I get lots of messages like this
tar: ././@LongLink: typeflag 'L' not recognized, converting to regular file
tar: ././@LongLink: typeflag 'L' not recognized, converting to regular file
tar: ././@LongLink: typeflag 'L' not recognized, converting to regular file
tar: ././@LongLink: typeflag 'L' not recognized, converting to regular file
....
and long names get truncated, for instance
db-derby-10.3.1.0-src/java/client/org/apache/derby/client/am/UpdateSensitiveBlobLocatorInputStream.java
->
db-derby-10.3.1.0-src/java/client/org/apache/derby/client/am/UpdateSensitiveBlobLocatorInputStream.j
Extracting the archive with GNU tar does not truncate the names.
If I recreate the archive with GNU tar and tells it to use a standard format
with "--format=ustar", Solaris tar has no problem with the long names.
According to the GNU tar manual, --format=ustar will produce a POSIX.1-1988
compatible archive, which supports file names up to 256 characters. As far as I
can see, 256 characters is sufficient for the source distribution.
Probably not a big problem since GNU tar is available on most platforms, but
generally I think using a standards-compliant format is better.

> Reporter: Rick Hillegas
> Assignee: Myrna van Lunteren

> 1) Problem unzipping derby_doc_plugin_1.1.0.zip and derby_ui_plugin_1.1.0.zip:
> rick doc-plugin (1.4) > unzip derby_doc_plugin_1.1.0.zip
> Archive: derby_doc_plugin_1.1.0.zip
> End-of-central-directory signature not found. Either this file is not
> a zipfile, or it constitutes one disk of a multi-part archive. In the
> latter case the central directory and zipfile comment will be found on
> the last disk(s) of this archive.
> unzip: cannot find zipfile directory in one of derby_doc_plugin_1.1.0.zip or
> derby_doc_plugin_1.1.0.zip.zip, and cannot find
> derby_doc_plugin_1.1.0.zip.ZIP, period.
> 2) Old problem: Filenames in the src-tar distribution are truncated. What
> is the use of this distribution?
> 3) Broken links in index.html:
> - Could not find link to pdf for Getting Started. The file is called
> getstartderby.pdf but the link references getstart.pdf
> - Could not find link to either of the html files for Working with Derby.
> The actual directory
> is workingwithderbytemp but should be workingwithderby
> - Could not find the pdf for Working with Derby either. The
> workingwithderby subdirectory doesn't exist under the pdf branch.
> - Could not find pdf for Admin Guide. The file is called
> derbyadmin.pdf but the link specifies adminguide.pdf
