Willy Tarreau 94b9abe200 MINOR: pattern: add pat_ref_purge_older() to purge old entries ... This function will be usable to purge at most a specified number of old entries from a reference. Entries are declared old if their generation number is in the past compared to the one passed in argument. This will ease removal of early entries when new ones have been appended. We also call malloc_trim() when available, at the end of the series, because this is one place where there is a lot of memory to save. Reloads of 1M IP addresses used in an ACL made the process grow up to 1.7 GB RSS after 10 reloads and roughly stabilize there without this call, versus only 260 MB when the call is present. Sadly there is no direct equivalent for jemalloc, which stabilizes around 800MB-1GB.		2020-11-05 19:27:09 +01:00
