[pmwiki-devel] RFC: Community poll for PageList link/category arguments
Petko Yotov
I hope you are all safe, and happy holidays if you're celebrating!
I've been working on some new features for version 2.3.0 and I'd like
your input.
If you have a few minutes, please look at this page:
https://www.pmwiki.org/wiki/PITS/01475
...and consider which ones of the proposed implementations may suit your
wiki and your editors best, and add your name.
I'd like to see some comments/votes and to release 2.3.0 by January 8.
2022, which will include implementing and documenting the new features.
If you have questions or suggestions, you can add them to the page, or
reply to the mailing list.
Thank you in advance.
Petko

First, this is a fabulous installation with 64817 pages! It will be
great indeed to benchmark the new feature.
Second, we need to look at the numbers between the start and end of the
functions, so the difference between the core and the recipe are even
greater:
422: 00,69 PageListTermsTargets begin count=64817
425: 01,09 PageListTermsTargets end count=164
1.09-0.69=0.4 seconds for the core processing
422: 00,76 PageListMultiTargets begin count=64817
425: 03,17 PageListMultiTargets end count=164
3.17-0.76=2.41 seconds for the recipe, that's about 6 times more
CPU-intensive.
Indeed, in 2.3.0, when you have link=SinglePage, then the original
scanning method is used, so the times should be very close to the
current ones.
When you're searching for links to multiple pages or to wildcards, the
new core algorithm is different from the one in the recipe, with fewer
loops, and I believe (hope) it will be faster than the current recipe.
Again, your installation will be a great place to verify this.

link=Year.199* or link=+Year.199* lists pages linking to any page with
the pattern, not to all pages, whether the target page exists or not.
The wildcard characters are about characters, not about existing pages:
? = exactly one character, any character
* = between zero and any number of any character(s)
The poll is more about a case like link=GroupA.*,GroupB.* then we need
to decide how we want it to behave.
Should it require at least one link to GroupA OR to GroupB like in the
recipe?
Should it require at least one link to GroupA AND at least one link to
GroupB? Or should this case be written as link=+GroupA.*,+GroupB.* ?

On PmWiki.org we only have about 10K pages, and here is our benchmark:
https://www.pmwiki.org/wiki/Test/CorePLMT2
Single page:
link=PmWiki.BasicEditing
17: 00.22 00.21 PageListTermsTargets begin count=10109
20: 00.25 00.24 PageListTermsTargets end count=70
That's 0.03 seconds.
Wildcard, multiple pages:
link=PmWiki.BasicEditin?,NoSuchGroup654.NoSuchPage987
52: 00.32 00.30 PageListTermsTargets begin count=10109
55: 00.39 00.37 PageListTermsTargets end count=72
That's 0.07 seconds, only 0.04s or 1/25th of a second slower than the
first one. I think it might be good enough for many people.
Note that the second search is case-insensitive, it returns 2 additional
pages which link to Pmwiki.BasicEditing (lowercase "w" in "Pmwiki")
which doesn't exist.
Not sure if I should do something about this case, or not.
