cl-emb speedup

Tomasz Skutnik — 2008-06-09T22:00:16

Hi. I've started some serious development using cl-emb, and found that it's template parsing/compilation was unbearably slow. Even simple few character template parsing and compilation results in massive CPU and memory burn. So I've profiled it a bit using SBCL statistical profiler and found that it was all due to very suboptimal use of ppcre:regex-replace-all. Long story short (well, not so long) regex-replace-all was alway passed strings, which resulted in very costly ppcre scanner building every time any template was parsed. Simple memoization in expand-template-tags did the trick - scanner object is built only on first use. Below you will find patch that modifies cl-emb accordingly. Code heavily borrows from Edi Weitz's Hunchentoot's scanner-for-get-param and Tim Bradshaw's memoize library. Thanks guys. Additionally patch exports new external function clear-expand-template-tag-hash, that clears internal cache. It's provided because template tags expansion depends on *emb-start-marker* and *emb-end-mark

In order to get CL-EMB's output to the browser, you need to call it from within your favorite web framework/tool and feed the results the way (stream, string) it's needed. CL-EMB isn't PHP. You could compare it to one aspect of PHP: templating and embedding code into text files. CLHP wants to be more like PHP. But the project seems to be a bit more quiet than CL-EMB. If you like Hunchentoot you could modify the test code and replace CL-WHO with CL-EMB, just to get a feel how to work this way. There's some code in CL-WIKI that uses CL-EMB, too. But I don't know if it's working with Hunchentoot. Regards, Stefan

Stefan, You are right, the CL-PPCRE included in Lispbox is an older version (much older, it would seem, given the changelog you quoted). I downloaded and installed the latest version (1.2.14) and the error no longer occurs. Thank you!

The locking function gets called whenever CL-EMB accesses a global hash table. IMPORTANT: The locking function must return the value of the function it calls! Example: (defvar *emb-lock* (kmrcl::make-lock "emb-lock") "Lock for CL-EMB.") (defun emb-lock-function (func) "Lock function for CL-EMB."
