How to use bucket more efficient?

[贾晓建 <jx...@cn.fujitsu.com>]

Hello everyone!

     In the article Introduction to Buckets and
<http://www.apachetutor.org/dev/brigades>  Brigades, the author mentions 

“””Note that we created a new bucket every time we replaced a character.
Couldn't we have prepared four buckets in advance - one for each of the
characters to be replaced - and then re-used them whenever the character
occurred?

The problem here is that each bucket is linked to its neighbours. So if we
re-use the same bucket, we lose the links, so that the brigade now jumps
over any data between the two instances of it. Hence we do need a new bucket
every time. That means this technique becomes inefficient when a high
proportion of input data has to be changed. We will show alternative
techniques for such cases in other articles.

“””

But I did not find the “other articles” the author mentioned! Would anyone
please tell me where to find this article or how to do when we want to
improve the efficiency of using buckets in such situation?

 

Thanks a lot!

Two answers to that:
 1. The work that started out as articles at apachetutor got diverted
    into my book (see sig), so there are far fewer articles than I
    no doubt envisaged when I wrote that.
 2. You should probably look at
    http://httpd.apache.org/docs/trunk/developer/output-filters.html
    which is not by me, but is more recent/up-to-date than the
    article you mention.
