Reporter: Alvaro Livraghi
Starting with v1.11.4, the Perl porting fails to dinamically set the
{{$VERSION}} variable when installing from CPAN or from {{{}.tar.gz{}}}.
After a bit of investigation, I noticed that the
{{[build.sh|https://github.com/apache/avro/blob/release-1.11.4/lang/perl/build.sh]}}
script no longer copies {{VERSION.txt}} (from {{{}../../share{}}}) as in
previous versions.
At the same time, the
{{[Makefile.PL|https://github.com/apache/avro/blob/release-1.11.4/lang/perl/Makefile.PL]}}
expects the version file to be in {{{}../../share/VERSION.txt{}}}, which, when
installing from CPAN or directly from {{{}.tar.gz{}}}, cannot exist.
This results in an unversioned Avro Perl installation as shown in the follow:
{code:bash}
cpanm Avro{code}
{noformat}
--> Working on Avro
Fetching http://www.cpan.org/authors/id/R/RS/RSKRABA/Avro-1.12.1.tar.gz ... OK
Configuring Avro-1.12.1 ... OK
Building and testing Avro-1.12.1 ... OK
Successfully installed Avro-1.12.1
1 distribution installed{noformat}
Indeed, checking the version reveals that it is not available:
{code:bash}
perl -MAvro\ v1.12.1{code}
{noformat}
Invalid version format (version required).
BEGIN failed--compilation aborted.
{noformat}
Even looking at the module file, I notice that the {{$VERSION}} variable isn't
initialized with the expected version number (v1.12.1) but it is empty:
{code:bash}
find ~/perl5/ -type f -name Avro.pm -exec grep -n '$VERSION' {} \;{code}
{noformat}
22:our $VERSION = '';{noformat}
This creates potential inconsistencies when installing libraries that depend on
{{{}Avro{}}}, as they can't verify its version.
Is it possible to revert to the previous approach?
