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).

  Use of uninitialized value $value in string eq at cpan/DB_File/t/db= -hash.t line 224.   Use of uninitialized value $values[0] in string eq at cpan/DB_File/= t/db-hash.t line 224.   Use of uninitialized value $value in lc at cpan/DB_File/t/db-hash.t= line 224.   Use of uninitialized value $h{""} in string eq at cpan/DB_File/t/db= -hash.t line 243.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value in numeric eq (=3D=3D) at cpan/DB_File/t= /db-hash.t line 252.   Use of uninitialized value $foo[18] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[36] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[48] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[58] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[59] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[60] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[62] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[63] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[92] in join or string at cpan/DB_Fi= le/t/db-hash.t line 261.   Use of uninitialized value $foo[114] in join or string at cpan/DB_F= ile/t/db-hash.t line 261.   Use of uninitialized value $foo[140] in join or string at cpan/DB_F= ile/t/db-hash.t line 261.   Use of uninitialized value $foo[187] in join or string at cpan/DB_F= ile/t/db-hash.t line 261.   Use of uninitialized value $foo[188] in join or string at cpan/DB_F= ile/t/db-hash.t line 261.   Use of uninitialized value $foo[189] in join or string at cpan/DB_F= ile/t/db-hash.t line 261.   1..166   ok 1   ok 2   ok 3   ok 4   ok 5   ok 6   ok 7   ok 8   ok 9   ok 10   ok 11   ok 12   ok 13   ok 14   ok 15   ok 16   ok 17   ok 18   ok 19   ok 20   ok 21   ok 22   not ok 23   not ok 24   not ok 25   ok 26   not ok 27   not ok 28   ok 29   not ok 30   ok 31   ok 32   ok 33   ok 34   ok 35   ok 36   not ok 37   ok 38   ok 39   ok 40   ok 41   ok 42   ok 43   ok 44   not ok 45   not ok 46   ok 47   ok 48   ok 49   ok 50   ok 51   ok 52   ok 53   ok 54   ok 55   ok 56   ok 57   ok 58   ok 59   ok 60   ok 61   ok 62   ok 63   ok 64   ok 65   ok 66   ok 67   not ok 68   ok 69   #

----------------------------------------------------------------- [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

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.

Thanks\,

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}'

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.
