Work with page cache, not instead of it

Description
My client wants Drupal to keep accurate hit counts for their articles and therefore cannot use Boost for them. However, their tag-based search page is fairly expensive to generate and we would love to use Boost for it. So what I want is to enable Boost for a subset of paths and leave the database-backed page cache enabled for everything else. However, enabling Boost disables the built in page cache complete.
For now this client has moved away from Boost so I am unlikely to implement this in the near term.
#1
I'll likely implement this in the 6.x branch.
#2
Need to see if this module can help out.
http://drupal.org/project/cacheexclude
#3
Looked at the above module and all it does is set
$GLOBALS['conf']['cache'] = FALSE;for pages it doesn't want cached, which corresponds tovariable_set('cache', CACHE_DISABLED).This is inside boost_admin_settings_submit()
// Forcibly disable Drupal's built-in SQL caching to prevent any conflicts of interest:variable_set('cache', CACHE_DISABLED);
Drupal's cache gets set via drupal_page_footer() => page_set_cache(). boost_exit() and _boost_ob_handler() are to late in terms of doing
$GLOBALS['conf']['cache'] = TRUE;. Need to see if I can move the drupal_get_headers() out of _boost_ob_handler() and into an earlier stage; via boost_preprocess_page(). Main goal is to enable drupal's cache when boost won't cache that page. Need to see if CACHE_AGGRESSIVE is compatible with boost; it gets evaluated in _drupal_bootstrap(), controls the calling of bootstrap_invoke_all('boot') (hook_boot()), bootstrap_invoke_all('exit') (hook_exit()). Boost has a hoox_exit() call but this only gets bypassed if the cache is set for that page & CACHE_AGGRESSIVE. So my guess is boost is compatible with CACHE_AGGRESSIVE.Long story short:
Inside new function boost_preprocess_page() IF boost is going to cache page THEN set $GLOBALS['conf']['cache'] = FALSE. Re-enable normal cache settings on performance page.
#4
man this is an annoying bug... #484756: Page Cache
#5
here is the initial patch for this
#6
More refined patch, decided to enable aggressive caching with boost.
#7
#8
committed.
#9
Display # of pages for each cache & ability to flush entire cache (core or boost) on performance page.
#10
moving additional things to #453426: Merge Cache Static into boost - Create GUI for database operations.
Main issue was fixed so marking this as fixed.
