When trying to build perl from git on a new laptop, I get test
failures in cpan/DB_File/t/db-hash.t​:

The test output contained a few lines with a few million NULs -- they
have been replaced (otherwise, perlbug would not accept the report).

-----------------------------------------------------------------
[Please describe your issue here]

When trying to build perl from git on a new laptop, I get test
failures in cpan/DB_File/t/db-hash.t​:

The test output contained a few lines with a few million NULs -- they
have been replaced (otherwise, perlbug would not accept the report).
...

This appears to be a duplicate of https://rt.cpan.org/Ticket/Display.html?id=125238.

That report suggests that the BerkelyDB library in MacOS is in a place that DB_File hasn't been configured to use. In the section "Let's make libdb work" from #125238, it says that the BerkeleyDB library is installed in /opt/local/lib/db48.

If that is the case here, edit the config.in file for DB_File and set

INCLUDE = /opt/local/include/db48
LIB = /opt/local/lib/db48

the rebuild & test DB_File.

Alternatively set the environment variables DB_FILE_INCLUDE to /opt/local/include/db48 and DB_FILE_LIB to /opt/local/lib/db48, the rebuild & test DB_File.

If this works, I'll add a note to the Troubleshooting section in the README

That seems to do the trick.

Do you know if MacOS ships with the Berkeley DB include file, db.h? Otherwise DB_File.xs wouldn’t compile at all.

Seems strange to have that include file, but not the library.

Actually – looking at your bug report again, most of the DB_File test harness passed. That means there needs to be a version of the Berkeley DB library available.

If you get a chance, could you see what this gives you when run in the DB_File source directory after you’ve run “make test” (without setting any of the INCLUDE/LIB variables to point to /opt/local/lib/db48)

  perl -Mblib -MDB_File -e 'print qq{Built with Berkeley DB ver $DB_File​::db_ver\n}'
  perl -Mblib -MDB_File -e 'print qq{Running with Berkeley DB ver $DB_File​::db_version\n}'

Built with Berkeley DB version 1

Version 1 ! Now I'm confused.

Running that test without messing with DB_File INCLUDE/LIB variables implies there already is a copy of the original version 1 Berkeley DB library (the one that DB_File was originally written for) on MacOS.

Why it is failing only one of the test is weird. Need to think about what to do nest.

I get the same thing, but after "brew install berkeley-db" get​:

$ cd cpan/DB_File
$ ../../perl -I../../lib -Iblib -MDB_File -E 'say "Built with Berkeley
DB ver $DB_File​::db_ver"'
Built with Berkeley DB ver 6.002032
$ ../../perl -I../../lib -Iblib -MDB_File -E 'say "Built with
Berkeley DB version $DB_File​::db_version"'
Built with Berkeley DB version 6.2

and all tests passing, so that is a workaround for people who need
DB​::File working.

Now back to the default situation. Apparently Berkeley DB is present
on macOS High Sierra but is located in libSystem.B.dylib rather than
in its own library​:

<https://discussions.apple.com/thread/8125401>

and it's buggy. Not sure how to work around that.

Actually, the Berkeley v1 functions appear to be in libsystem_c​:

$ nm /usr/lib/system/libsystem_c.dylib | egrep
'dbpanic|dbopen|bt_open|hash_open|rec_open|dbpanic'
00000000000142d8 T ___bt_open
0000000000016eab T ___dbpanic
0000000000016ee4 T ___hash_open
000000000001bbd0 T ___rec_open
0000000000016e39 T _dbopen

and the /usr/include/db.h appears to be consistent with that (ancient
BSD license with no mention of Sleepycat or Oracle). Apple includes
much later versions of Berkeley DB in its open source listings​:

<https://opensource.apple.com/source/BerkeleyDB/>

but where that gets installed (or if it does) is something I have not
managed to figure out. It may only be used as part of some other
package.

Where things go obviously wrong with the db-hash.t test is right here​:

# tie to the same file again, do not supply a type - should default to HASH
ok(22, $X = tie(%h,'DB_File',$Dfile, O_RDWR, 0640) );

Right before this %h is empty, and right after it, %h has 10 entries.
The keys are each 4128769 bytes long consisting mostly or entirely of
NULs (hard to tell with the debugger) and the values are undef. But
there is probably something wrong before that as the file referenced
by $Dfile is over 200MB​:

$ ls -l dbhash.tmp
-rw-r----- 1 craig staff 205520896 Jun 21 17​:31 dbhash.tmp

That zips down to about 200K, but that's still a bit big to attach here.

I don't know if or when I'll be able to debug this further.
