I actually agree with him; it was a quick hack that is not at all elegant. It basically loops through every key in the cache comparing against the regex, blocking all other requests while it runs. On a large cache that means it locks up memcached for a long period of time, causing client timeouts and so forth.<br><br>We used it once or twice after I wrote it last year, then decided it was too painful and haven't touched it since. It is not something I have any interest in fielding support questions about (since I am fully aware that it sucks) so I haven't been inclined to publish it. Anyone who wants to can probably reproduce it pretty easily; go for the most naive implementation you can think of and you'll probably be pretty close.<br></span></blockquote></div><div><br class="webkit-block-placeholder"></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>What were you using as a regex engine?<br class="webkit-block-placeholder"></div><br><div> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div>-- </div><div>Dustin Sallings</div><br class="Apple-interchange-newline"></span> </div><br></body></html>
