http://issues.apache.org/bugzilla/show_bug.cgi?id=29852 CacheGcInterval values to stop GC Summary: CacheGcInterval values to stop GC Product: Apache httpd-1.3 Version: 1.3.29 Platform: Other OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: mod_proxy AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] The documentation for mod_proxy says that if CacheGcInterval is not set, no garbage collection will be performed, and the cache will grow indefinitely. But, it's behaviour doesn't seem to be as specified. The default CacheGcInterval of 1 hour is used if no value is specified. Line #110 mod_proxy.h #define DEFAULT_CACHE_GCINTERVAL SEC_ONE_HR Ofcourse, the above can be easily resolved by updating the documentation. Now, to the issue I have. How do you stop apache mod_proxy GC (if necessary)? See the related code below... mod_proxy.c static const char * set_cache_gcint(cmd_parms *parms, void *dummy, char *arg) { ... if (sscanf(arg, "%lg", &val) != 1) return "CacheGcInterval value must be a float"; psf->cache.gcinterval = (int)(val * (double)SEC_ONE_HR); ... } proxy_cache.c static int should_proxy_garbage_coll(request_rec *r) { ... time_t every = conf->gcinterval; if (cachedir == NULL || every == -1) return 0; // do GC ... } In order to make *every* variable to a value of -1, we need to specify CacheGcInterval to a value in the range -0.00055 to -0.00028. Very obscure values. My suggestion would be stop all apache mod_proxy GC if the user specifies any negative value for CacheGcInterval. The code change involved would be minor as shown below - proxy_cache.c static int should_proxy_garbage_coll(request_rec *r) { if (cachedir == NULL || every < 0) return 0; // do GC } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
