This script postprocesses XML dumps from dumpBackup.php to add
page text which was stubbed out (using --stub).
Usage: php dumpTextPass.php [<options>]
Options:
- --prefetch <file> Use a prior dump file as a text source where possible.
- (Requires PHP 5.0+ and the XMLReader PECL extension)
- --quiet Don't dump status reports to stderr.
+ --stub=<type>:<file> To load a compressed stub dump instead of stdin
+ --prefetch=<type>:<file> Use a prior dump file as a text source, to save
+ pressure on the database.
+ (Requires the XMLReader extension)
+ --maxtime=<minutes> Write out checkpoint file after this many minutes (writing
+ out complete page, closing xml file properly, and opening new one
+ with header). This option requires the checkpointfile option.
+ --checkpointfile=<filenamepattern> Use this string for checkpoint filenames,
+ substituting first pageid written for the first %s (required) and the
+ last pageid written for the second %s if it exists.
+ --quiet Don't dump status reports to stderr.
--report=n Report position and speed after every n pages processed.
- (Default: 100)
-END
+ (Default: 100)
+ --server=h Force reading from MySQL server h
+ --current Base ETA on number of pages in database instead of all revisions
+ --spawn Spawn a subprocess for loading text records
+ --help Display this help message
+ENDS
