545 | =head3 VERSION CHECKING |
|
|
546 | |
|
|
547 | BerkeleyDB comes in various versions, many of them have minor |
|
|
548 | incompatibilities. This means that traditional "at least version x.x" |
|
|
549 | checks are often not sufficient. |
|
|
550 | |
|
|
551 | Example: set the log_autoremove option in a way compatible with <v.47 and |
|
|
552 | v4.7. Note the use of & on the constants to avoid triggering a compiletime |
|
|
553 | bug when the symbol isn't available. |

|
|
561 | |
|
|
562 | The C<BDB::VERSION> function, when called without arguments, returns the |
|
|
563 | Berkeley DB version as a v-string (usually with 3 components). You should |
|
|
564 | use C<lt> and C<ge> operators exclusively to make comparisons. |
|
|
565 | |
|
|
566 | Example: check for at least version 4.7. |
|
|
567 | |
|
|
568 | BDB::VERSION ge v4.7 or die; |
|
|
569 | |
|
|
570 | =item BDB::VERSION min-version |
|
|
571 | |
|
|
572 | Returns true if the BDB version is at least the given version (specified |
|
|
573 | as a v-string), false otherwise. |
|
|
574 | |
|
|
575 | Example: check for at least version 4.5. |
|
|
576 | |
|
|
577 | BDB::VERSION v4.7 or die; |
|
|
578 | |
|
|
579 | =item BDB::VERSION min-version, max-version |
|
|
580 | |
|
|
581 | Returns true of the BDB version is at least version C<min-version> (specify C<undef> or C<v0> for any minimum version) |
|
|
582 | and less then C<max-version>. |
|
|
583 | |
|
|
584 | Example: check wether version is strictly less then v4.7. |
|
|
585 | |
|
|
586 | BDB::VERSION v0, v4.7 |
|
|
587 | or die "version 4.7 is not yet supported"; |
