Description Aurimas Fišeras 2006-10-21 21:15:28 UTC
Extend this option, by adding the timestamp that changes behavior to:
"Skips all but the last revision before the specified timestamp"

Patch to extend --filter:latest

A patch to add such behavior.
Comment 2 Aurimas Fišeras 2006-10-21 21:21:29 UTC

Patch to extend --filter:latest (fixed)

Comment 3 Aurimas Fišeras 2006-10-22 10:12:44 UTC
Created attachment 2535 [details]
Patch to extend --filter:latest

fixed a serious bug.
Comment 4 Brion Vibber 2006-10-24 11:32:04 UTC
It might be cleaner to instead have a 'before' or 'up to' filter that passes *all* revisions up to the given time.
With the latest filter applied after it on the pipe, this would perform the desired function while also being more flexible.

mwdump -filter=before:<timestamp>

Good suggestion. Filter rewritten.
You can get the previous effect using these filters:
--filter=latest --filter=before:<timestamp>
Comment 6 Aurimas Fišeras 2006-10-25 06:51:03 UTC

mwdump -filter=after:<timestamp> -filter=before:<timestamp>


Enables to create possibly useful dumps for statistical analysis, etc.

--filter=after:2004-01-01T00:00:00Z --filter=before:2005-01-01T00:00:00Z
Comment 7 Brion Vibber 2006-10-25 08:23:09 UTC
The two filter classes look identical except for one method call. :)
Duplicated code always increases the risks of bugs being introduced when things are changed;
it would be cleaner to avoid the duplicated code and make these on one base class.
Comment 8 Aurimas Fišeras 2006-10-25 08:42:35 UTC
Created attachment 2553 [details]
mwdump -filter=after:<timestamp> -filter=before:<timestamp>

Properly rewritten.
Comment 9 Brion Vibber 2006-10-25 12:55:54 UTC
