db_file's Issues

DB_File leaks handle on croak

In bleadperl under Address Sanitizer, 3 of the test files (db-btree, db-hash, db-recno) report leaks. This appears to be because a croak doesn't close the recently-opened DB handle, thus not freeing its resources. The attached proof-of-concept diff makes the issue apparently go away (tested only
on DB 5.3.28)

db_file.txt

ParseOpenInfo() leaks if it croaks

ParseOpenInfo() initially mallocs a DB_File_type buf. If it then croaks for any reason, this buffer leaks. This shows up in bleadperl as failing tests under clang's Address Sanitizer. A sample failure script (reduced from db-btree.t) is

use DB_File; 
my $filename = "xyz";
my @x;
eval { tie @x, 'DB_File', $filename, 0x42, 0640, $DB_BTREE } ;
unlink $filename;

Can a LICENSE file be added?

Hello!

I'm submitting a recipe for DB_File to conda-forge. I was wondering if you could include a LICENSE file in your repo.

Or, would you rather I manually include a license for Perl_5 (https://dev.perl.org/licenses/) (e.g. text for Artistic License or GPLv1+, or both)

Thank you!

Building with gcc12 emits build-time warnings -- but only in Perl 5 blead, not in DB_File's own repo

When compiling Perl 5 blead (here, a threaded build on FreeBSD-12) using gcc12 as the C-compiler, make test_prep emits build-time warnings during compilation of cpan/DB_File/DB_File.xs. But when I use that same perl to build DB_File in a checkout from its own repository, I do not get those warnings.

Here is the relevant part of the output from make test_prep run in Perl 5 blead at commit 765cd54646, using gcc12 on FreeBSD-12 and building with threads:

$ cat DB_File.blead.gcc12.make.output.txt 
./miniperl -Ilib make_ext.pl lib/auto/DB_File/DB_File.so  MAKE="make" LIBPERL_A=libperl.a LINKTYPE=dynamic

I always like to eliminate build-time warnings from Perl 5's make as much as possible. If I apply the following patch to Perl 5 blead, those warnings are eliminated:

     } while (0)

... and perl builds and tests successfully, as in this smoke-me branch.

But I concede that I find the absence of build-time warnings when I build in DB_File's own repository surprising.

DB_File-1.858 does not build on Rocky Linux 8.8 (aarch64)

DB_File-1.858 does not build on Rocky Linux 8.8 due to an error caused by an unknown architectural extension called ssbs when compiled with GCC-12.2.0 on an AWS c6g-class instance.

This doesn't seem to be an issue for x86_64.

Any insights you could offer would be appreciated.

Difficulty building on HPC (Linux)

Hi, I've referenced previous resolved issue #14 to cpan DB_File using:

Any help/insight would be greatly appreciated, I am not the best at perl but I did try to troubleshoot but to no avail, thank you!

Licence confusion

The COPYRIGHT section of DB_File's main man page (https://metacpan.org/pod/DB_File#COPYRIGHT) refers to "the Berkeley DB FAQ (at http://www.oracle.com/technology/products/berkeley-db/db/index.html)," quoting some text from it which explains that it is not necessary to license Berkeley DB to use it in Perl scripts.

Unfortunately, that link now goes somewhere else (https://www.oracle.com/database/technologies/related/berkeleydb.html), which isn't an FAQ page. There is a "Berkeley DB FAQ" link on that page, which goes to https://www.oracle.com/database/technologies/berkeleydb-db-faq.html, but there is no sign of the text quoted in DB_File's man page...

That very much leaves one wondering what the licence situation now is, since Berkeley DB's own licences (a choice of two are available) do not sound as friendly as the text quoted in DB_File's man page would suggest.

Please could you clarify what the current situation is, and update the man page link and/or text appropriately.

Can't build on OS X (arm)

Not sure if this requires homebrew berkeley-db. In any case, I do have that package installed, but this doesn't help

export LDFLAGS="-L/opt/homebrew/opt/berkeley-db/lib"
export CPPFLAGS="-I/opt/homebrew/opt/berkeley-db/include"
