<p>In previous releases of Berkeley DB, Recno access method backing source text
|
|||
|
|
files were opened using the ANSI C fopen function with the "r" and "w"
|
|||
|
|
modes. This caused Windows systems to translate carriage-return and
|
|||
|
|
linefeed characters on input and output and could lead to database
|
|||
|
|
corruption.</p>
|
|||
|
|
<p>In the current release, Berkeley DB opens the backing source text files using
|
|||
|
|
the "rb" and "wb" modes, consequently carriage-return and linefeed
|
|||
|
|
characters will not be translated on Windows systems.</p>
|
|||
|
|
<p>Applications using the backing source text file feature on systems where
|
|||
|
|
the "r/w" and "rb/wb" modes differ should evaluate their application as part
|
|||
|
|
of upgrading to the 4.5 release. There is the possibility that
|
|||
|
|
characters have been translated or stripped and the backing source file
|
|||
|
|
has been corrupted. (Applications on other systems, for example,
|
|||
|
|
POSIX-like systems, should not require any changes related to this
|
|||
|
|
issue.)</p>
