Synopsis:
"If you fill up your squid cache, CPU will go to 100% but the cache will not be
cleaned up."
PR: 18920
Submitted by: Mike Harding <mvh@ix.netcom.com>
Obtained from: http://www.squid-cache.org/Versions/v2/2.3/bugs/
- the distributed patches got regenerated to have the correct paths
- disable optimization because of gcc bugs (as recommended by squid folks)
- list a few new --enable/--disable options
Squid 2.0 is the-version-formerly-known-as-1.2.
v2.0 has NOVM-like functionality internally, so there's no seperate
NOVM version. v1.1.* is no longer officially supported.
Note: the b14 -> b15 change will loose your cache unless you take
the steps on http://squid.nlanr.net/ to recover it.
Read the Changelog for details, this is a fairly large update.
Major changes:
- the URL and SHA cache key methods are gone, MD5 is the only option.
- the swap.state system has been redesigned as a transaction log for
much faster restarts and crash recovery.
- SIZE on ftp binary transfers.
- Lots of bug fixes and code cleanups.

WARNING, with beta12 we are starting to stuff object metadata into
the beginning of objects on disk. With beta13 we have changed the
"swap.state" file format to binary instead of text. When you run this
version for the first time you WILL LOSE YOUR CACHE!
The previous warning still stands:
This is BETA software. Do not run this on your production systems.
Logfile formats are subject (and likely) to change at any time without
warning.
Index: like posix says, rather than going into dummy mode. The distributed
patches are generated with standard cvs and don't have ache's hack (which
doesn't work when new files are added anyway).

"This is BETA software. Do not run this on your production systems.
Logfile formats are subject (and likely) to change at any time without
warning.
Here is a brief list of the major features of this version:
HTTP/1.1 persisitent connections.
Lower VM usage; in-transit objects are not held fully in memory.
Totally independent swap directories.
Customizable error texts.
FTP supported internally; no more ftpget.
Asynchronous disk operations (optional, requires pthreads library).
Internal icons for FTP and gopher directories.
snprintf() used everywhere instead of sprintf().
...and many more!
"
As well, there is support for using MD5 or SHA hashes of URL's in the
cache index for space (and speed?) savings, SNMP support, poll(2) is
used by default, etc.
