The "file" produced by the text back end is a directory with one
|
|
file per group.
|
|
</p>
|
|
|
|
<p>
|
|
When the file is open, it is locked by the current process. No other
|
|
process can read/write the same file. This guarantees that the
|
|
representation in memory is consistent with the file and avoid
|
|
re-reading the file before writing.
|
|
To lock the file, we lock the <code>.lock</code> file which is present in the
|
|
directory.
|
|
</p>
|
|
|
|
<p>
|
|
The file is written when closed, or when the flush function is called.
