 168         - Added separate config line (neighbor_type_domain) for modifying
 169           neighbor type (parent vs. sibling) for certain domains.  Adding
 170           it to cache_host_domain doesn't provide needed flexibility.
 171         - Added User-Agent log patch (Joe Ramey).
 172         - Added httpd-accel Host: patch (Miguel A.L. Paraz).
 173         - Changed ident lookup stuff to require the lookup before
 174           checking ACL's.  If you have 'ident_lookup on' then this
 175           may cause noticable delay while waiting for the ident
 176           lookup.
 177         - Fixed storeSwapOutHandle() FMR bug.
 178         - Stopped inserting incorrect Host: header for proxy-HTTP requests.

 193         - Fixed asciiConnLifetimeHandle() to force storeAbort() for
 194           pending objects.
 195         - Made lots of variables and args 'const' (Markus Gyger).
 196         - Added cachemgr password support in squid.conf (Yaroslav M.
 197           Levchenko).  Each cachemgr operation may have a separate
 198           password.  Shutdown and all "log" operations must be
 199           password-protected.
 200         - Removed debug_trap() calls in squid_error_entry().
 201         - Removed InvokeHandlers() call from StoreAbort().

 206         - Made number of first- and second-level swap directories
 207           configurable (Ralph Loader).

 212         - Fixed errors being returned as empty objects.
 213         - Changed order of sanity checks in neighborsUdpAck().
 214         - Made swap log pathname configurable with 'store_swap_log'.
 215         - Made 'http_accel virtual 80' same as -V on command line.
 216         - Fixed string termination bug in base64_decode() (Joe Ramey).
 217

 230                 - store_avg_objects_size
 231         - Fundamental changes to object TTLs; now think in terms of
 232           refresh times.  Replaced 'ttl_pattern' with 'refresh_pattern'.
 233         - Dropped 'http', 'ftp', and 'gopher' config options.
 234         - Added a single 'maximum_object_size' value.
 235         - Moved storeStartDeleteBehind() calls from http/ftp/gopher to
 236           storeAppend().
 237         - Moved storeClientListAdd() call from store to client/icp
 238           because of storeClientCopy() race condition between IMS
 239           replies and objects in delete behind mode.
 240         - renamed TCP_EXPIRED* to TCP_REFRESH*.
 241         - Stopped appending error messages to partially delivered
 242           objects.
 243         - Removed protoUnregister() call in icpDetectClientClose()
 244           as probable cause of storeReleaseRequest() warnings.

 251         - Fixed process RSS value for SGI (Ed Knowles).
 252         - Fixed parseAddressLine() to use gethostbyname(3) because
 253           its called before ipcache_init(). (Miguel A.L. Paraz)
 254         - Fixed announce bug since beta7 causing caches to be announced
 255           regardless of 'announce_to' setting.  (Paul Southworth)
 256         - Fixed pinger 'last_check_time' bug.
 257         - Changed storeEntry->flag and storeEntry->refcount back to
 258           32-bit ints.

 275
 276         - Added client_db.c; keeps stats on clients, use cachemgr
 277           to view client list.
 278         - Stop sending ICP_OP_DENIED to clients if 95% of their
 279           queries are denied (then they'll think we're dead).
 280         - Fixed objects getting stuck in VM when handling aborted
 281           requests in icpHandleIMSReply().
 282         - If IMS verification fails, send the old object and log it
 283           as TCP_EXP_FAIL_HIT.
 284         - Added Host: header to HTTP requests.

 289         - Added some missing "entry->refcount++"
 290         - Changed StoreEntry->timestamp to be the last verification time.

 292         - Fixed stuck objects from "304 Not Modified" responses without
 293           final blank line.
 294         - Added failure detection to icmpRecv().
 295         - Fixed backwards logic in debug_trap().
 296         - Fixed neighbor caches remaining in 'DEAD' state.  Reorganized
 297           handling ICP replies so neighborsUdpAck gets called for
 298           most every reply.
 299
 300 Changes to squid-1.1.beta7 (October 14, 1996):
 301

 323           nonblocking connection handling code from other modules.
 324         - Improved cache memory usage.  Now cache_mem specifies the
 325           size of the in-memory data pool.  Hot objects use whatever
 326           space is not used by in-transit objects.
 327         - Removed 'max_hot_object_size' config option.

 367
 368 Changes to squid-1.1.beta3 (September 16, 1996):
 369

 385         - Includes squid-1.0 changes up to 1.0.16.
 386         - s/__STRICT_ANSI__/__STDC__/g
 387
 388 Changes to squid-1.1.beta2 (September 12, 1996):
 389
 390         - Switched to ANSI style coding.
 391         - Fixed UDP_HIT_OBJ objects ignoring 'proxy-only' setting.
 392         - Added setting cachemgr.cgi fields from query string
 393           (Neil Murray).
 394         - Split log type TCP_IFMODSINCE into TCP_IMS_HIT and
 395           TCP_IMS_MISS
 396         - Replaced proto_hit() and proto_miss() with proto_count()
 397           which looks at log_type argument to calcultate hits
 398           and misses.
 399         - Split CacheInfo into HTTPCacheInfo and ICPCacheInfo.
 400         - Placed call to proto_count() just after log_append()
 401           so we only need it in one place.
 402         - Made a lot of proto.c functions static and added prototypes.
 403         - Fixed icpProcessRequest() bug.  Need to check EXPIRED
 404           before IMS.
 405         - Fixed aclDestroyDenyInfoList() to NULL free'd lists.
 406         - Fixed storeDirClean() to unlink files which should be
 407           directories (Cord Beerman).
 408         - Added ICMP support.  Source ping will use ICMP packets if
 409           compiled with -DUSE_ICMP=1 and started with root privleges.
 410
 411 Changes to squid-1.1.beta1 (September 12, 1996):
 412
 413         - Fixed stupid coredump bug in storeGetSwapSpace().
 414         - Cleaned up gopher.c; prototypes, make functions static, etc.
 415         - Added READ_DEFERRED entry flag.  Only extend lifetime when
 416           first entering deferred mode.
 417         - Added debug_trap() to replace some fatal_dump()'s.  Now use
 418           debug_trap for non-fatal errors.  If -C option is set,
 419           then debug_trap is the same as fatal_dump.
 420
 421 Changes to squid-1.1.alpha18:
 422
 423         - Fixed storeCheckPurgeMem() to both 'purge' *and* 'release'
 424           objects as needed.
 425         - Fixed up RWStateCallbackAndFree() to prevent it from getting
 426           called twice.
 427         - Added 'deny_info' support for redirecting denied requests to
 428           a specific URL (maex@space.net).

 430         - Fixed parent-stays-dead-bug by removing PING_WAITING
 431           check in icpHandleIcpV?().
 432         - Changed debug log timestamp format.
 433         - Fixed coredump-causing bugs in icpHandleIMSReply().
 434         - Fixed FMR bug in neighborsUdpAck() for UDP_HIT_OBJ replies.
 435         - Fixed up InvokeHandlers() to clear handler before calling.
 436         - Added -k signal option to signal a running Squid (Markus Gyger).
 437         - Removed dynamic_array code.
 438
 439 Changes to squid-1.1.alpha17:
 440
 441         - Added more IMS support.  Now Squid issues IMS requests for
 442           expired objects in the cache.  Log type will be either
 443           TCP_EXPIRED_HIT if the server sends "304 Not Modified" or
 444           TCP_EXPIRED_MISS if the server send a new object.
 445         - Added Config.expireAge and 'expire_age' to config.
 446         - Fixed storeGetMemSpace() bug; need to check
 447           storeCheckPurgeMem() instead of storeEntryLocked().
 448         - Renamed icp_hit_or_miss() to icpProcessRequest().
 449         - Changed mkrfc850() to use normal variable instaed of a
 450           pointer.
 451         - Removed store_entry member from fd_table[] in comm.h.
 452         - Changed httpSendRequest to not tack Squid onto the 'User-Agent'
 453           line, Use HTTP/1.1 'Forwarded' instead.
 454         - Removed icpProcessHIT() which only called icpSendMoreData().
 455         - Removed icpProcessIMS() which only called icpGetHeadersForIMS().
 456         - Removed some 'Reset header fields for reply' crap.
 457         - added old_entry member to icpStateData for handling IMS
 458           requests.
 459         - Added 'locks' member to ipcache_entry; need to lock an
 460           ipcache entry during ipcache_call_pending().
 461         - Removed ipcache_call_pending_badname().
 462         - Cleaned up setting/clearing IP_LOOKUP_PENDING bit.
 463         - Removed storeEntryLocked() trap in storePurgeMem().
 464         - Added storeCheckExpired().
 465         - Removed storeWalkThrough() and removeOldEntry(), changed
 466           storePurgeOld() to do the walking through instead.
 467         - Added storeConfigure() so HUP signal affects store_swap size.
 468         - Replaced some parsing functions with parseMinutesLine().
 469         - Added StoreEntry flag bit ENTRY_NEGCACHED.
 470         - Added storeNegativeCache().
 471
 472 Changes to squid-1.1.alpha16:
 473
 474         - Fixed ipcache TTL bug from new ipcache_parsebuffer().
 475         - Copied recent ipcache.c changes to fqdncache.c
 476         - Copied icpHandleIcpV2() fix to icpHandleIcpV3().
 477         - incorporate squid-1.0.12 changes.
 478
 479 Changes to squid-1.1.alpha15:
 480
 481         - Removed 'bad swap_status' trap in icpHandleIcpV2.
 482           Now skip ICP replies for StoreEntry's with ping_status
 483           != PING_WAITING.
 484         - Fixed numerous compiler problems.
 485
 486 Changes to squid-1.1.alpha14:
 487
 488         - Fixed ENTRY_DISPATCHED bug.  ENTRY_DISPATCHED was not always
 489           getting set (e.g. for requests matching hierarchy_stoplist).
 490           This could cause multiple calls to storeAbort() for the same
 491           entry.
 492         - With ENTRY_DISPATCHED now fixed, call squid_error_entry()
 493           from protoUnregister() for StoreEntries which have not
 494           been dispatched.
 495         - Fixed 'quick_abort' parsing bug.
 496         - NULL terminate too-long URL strings in urlParse().  Still
 497           need fix to somehow handle these.
 498         - Added shadow password patch from John Saunders
 499           <johns@rd.scitec.com.au>
 500         - Added _dns_ttl_ hack from bne@CareNet.hu to get real TTL
 501           values from DNS queries.  See Release-Notes-1.1.txt for more
 502           info.
 503         - Added better '304 Not Modified' reply from Jaeyeon Jung
 504           <jyjung@cosmos.kaist.ac.kr>.
 505         - Rewrote ipcache_parsebuffer().
 506         - Fixed stupid clientProxyAuthCheck() bugs.
 507         - Made IP cache size configurable with 'ipcache_size'.
 508         - Fixed bug parsing 'cache_swap_low'.
 509         - Added -b option to ftpget to limit data transfer rate
 510           (bytes/sec).  Specify on 'ftpget_options' in config file.
 511         - Miscellaneous filedescriptor management cleanup.
 512         - Renamed function getFromCache() to protoStart().
 513         - Added delays when forking dnsservers, redirectors, and
 514           ftpget.
 515         - Includes 1.0 changes up to 1.0.11.
 516
 517 Changes to squid-1.1.alpha13:
 518
 519         - oops, there was no alpha13.
 520
 521 Changes to squid-1.1.alpha12:
 522
 523         - Rewrote storeGetMemSpace().
 524         - Fixed hot_vm accounting; only count objects which are added
 525           to the IN_MEMORY table.
 526         - Changed protoUndispatch() to never call squid_error_entry().
 527           Should fix storeSwapOutHandle() and 'HELP! Someone is
 528           swapping out a bad entry' coredumps.
 529         - Report all error pages to the debug log.
 530         - Added -i option which forces IP cache entry to be invalidated
 531           just after an object retrieval begins.
 532         - Includes all squid-1.0 changes up to squid-1.0.10.
 533         - Added patch from srb@cuci.nl (Stephen R. van den Berg) for

 546         - Changed fqdnFromAddr() to copy inet_ntoa() result into a
 547           static buffer.
 548         - Fixed storeDirClean() printf format.
 549
 550 Changes to squid-1.1.alpha10:
 551

 567
 568         - Removed all references to hierarchy.log.

 570           _hierarchyLogData structure.
 571         - Fixed "tty input" bug where a reverse lookup request was
 572           written to stdout.
 573         - Cleaned up pointers in protoUnregister().
 574         - Includes all squid-1.0 changes up to squid-1.0.6.
 575         - cache_swap 0 is allowed (proxy only server, no swapping), mainly
 576           intended for fast maintenance startups where the system already
 577           has to be running, but the disk(s) have not been fsck'd yet.
 578         - quick_abort actually works now
 579         - quick_abort functionality made conditional
 580         - ttl_pattern storage wasn't being cleaned upon a reread of
 581           the config file (the patterns were added only, got duplicates)
 582         - ttl_force_pattern a new config option to override the settings
 583           of certain pages despite (or because) of enforced low expiry times

 598 Changes to squid-1.1.alpha6:
 599
 600         - Changed storage manager to use a two level directory
 601           structure.  This makes squid-1.1 incompatible with squid-1.0!
 602           (Mark Treacy).
 603         - Added last modification time to the StoreEntry structure, and
 604           the swap log.
 605         - Changed how memory passed to comm_write() gets freed.  Now
 606           pass in a free handler function which gets called when the
 607           RWStateData structure is destroyed.
 608         - Other misc cleanup.

 616
 617 Changes to squid-1.1.alpha5:
 618
 619         - Got Asynchronous I/O stuff to compile and run on IRIX 5.3
 620         - Cleaned up diskHandleWrite()
 621         - Added free() handler to struct dwrite_q so diskHandleWrite()
 622           can free memory after its been written.
 623         - Changed file_open() to not allow files to be opened O_RDWR.
 624         - Changed file_open() to always set O_APPEND for O_WRONLY files.

 644           'max' are allocated.
 645
 646 Changes to squid-1.1.alpha3:
 647
 648         - Added Asynchronous Disk I/O routines from Pete Bentley.

1053         - Rewrote SSL/CONNECT handlers.  Now doesn't use a StoreEntry.
1054         - Fixed some aborted objects getting stuck in VM bug.
1055         - Fixed ftpget PASV reply sscanf to work for VMS ftpd.
1056         - Changed FTP URL parsing to use urlParse().
1057         - Changed ftpget to skip RETR command if URLs ends with '/'.
1058         - Changed ftpget to display README at the bottom if there are other
1059           server messages.
1060         - Changed ftpget to not reopen a new data connection
1061           if one is already open.
1062         - Fixed handling of FTP URLs with spaces (and other unsafe characters)
1063         - Changed ftpget to only generate BASE HREF if the FTP URL does
1064           not end with '/'.
1065
1066 Changes to squid-1.0.beta5:
1067
1068         - Fixed cachemgr to send 'HTTP/1.0' on request so it works
1069           with beta4 fixes to icp.c.
1070
1071 Changes to squid-1.0.beta4:
1072
1073         - Added a handler to restart the ftpget server.
1074         - Fixed access checks for ICP by parsing the requested URL.
1075         - Added "magic marker" to ftpget-generated errors so they can
1076           be negative-cached.
1077         - Added a small run-time check to configure to see if signal
1078           handlers should be restarted after invocation (ala SYSV).
1079         - Determine Maximum filedescriptors in configure and change
1080           FD_SETSIZE if needed.
1081         - Changed read stall algorithm for HTTP.  No don't wait until
1082           the object is in DELETE_BEHIND mode to stall the server read
1083           and wait for the client to catch up.  Also changed from 4k to
1084           16k read buffer.
1085         - Fixed HTTP request parsing to check for blank line at the
1086           end of all requests.  Symptoms were "connection reset"
1087           messages.
1088
1089 Changes to squid-1.0.beta3:
1090
1091         - Added ftpget '-C minport:maxport' option
1092         - Fixed PROTO_MAX fencepost bug in stat_init().
1093         - Fixed Fixed CheckQuickAbort() coredump.
1094         - Fixed disabling store.log and hierarchy.log when set to "none"
1095         - Fixed numerous problems related to setuid().
1096         - Fixed 'check_cache.pl' to use new swaplog format (without "FILE").
1097         - Fixed ACL coredumps when checking NULL words.
1098         - Changed pid_filename to be written and unlinked as root.
1099         - Added "-i seconds" option to 'client' for testing IMS GET.
1100         - Fixed a bug where an IMS request caused the valid object to
1101           get ejected from the cache.
1102         - Fixed continual DEAD_PARENT/REVIVE bug
1103         - Fixed ERR_INVALID_URL bug for URLs with a password field.
1104         - Added to Release-Notes info about converting 'cache/log' and
1105           difference between stoplists and ttl_pattern.
1106
1107 Changes to squid-1.0.beta2:
1108
1109         - Fixed /bin/csh "$#argv" leftover in RunCache.
1110         - Fixed ACL day-of-week bitmask bug.
1111         - Fixed missing checks for WAIS in some places.
1112         - Fixed chdir(swappath(0)) bug; do chdir() after storeInit().
1113         - Changed enumerated structure members to be defined outside
1114           of the structure itself (for AIX).
1115         - Changed ftpget to fork before reading the request and make
1116           sure the entire request is read.
1117
1118 Changes to squid-1.0.beta1 (Apr 19, 1996) from Harvest cached-1.4.pl3:
1119
1120         - Added a "server mode" to ftpget.  Now the (much smaller)
1121           ftpget process forks for each FTP request.
1122         - Added support for If-Modified-Since GET requests.
1123         - Added support for SSL and https objects.
1124         - Added background processing for rebuilding the disk store
1125           while serving requests.  Cache can now serve requests immediately.
1126         - Added a 'reconfigure' feature activated by SIGHUP.  The config
1127           file is re-read and most changes will take effect.
1128         - Added an internal flag for using private keys with ICP queries
1129           to neighbors.  If any neighbor returns a reqnum field of zero,
1130           then disable using private keys.  But still use private
1131           keys for things with bypass the ICP query step (such as POST
1132           and IMS-GET).
1133         - Added a function to verify content-lengths.  Objects with
1134           mismatched (but non-zero) content lenghts will be ejected.
1135         - Added clean shutdown mode.  On SIGTERM the incoming HTTP socket
1136           is closed.  Active clients are given a lifetime of 30 seconds
1137           (configurable).  Process exits when all sockets are closed.
1138         - Added support for large POST objects.
1139         - Added "store.log" which logs RELEASE/SWAPIN/SWAPOUT events.
1140         - Added announce feature to squid; no longer external program.
1141           If enabled, a running cache will announce itself every 24 hrs.
1142         - Added support for FTP URLs with non-default ports.
1143         - Added new Access Control List scheme.
1144         - Added Forwarded: header to proxy HTTP requests (HTTP/1.1 feature).
1145         - Added weights neighbors.
1146         - Added urlParse() which strips off default ports and
1147           makes hostnames all lowercase.
1148         - Added (section,level) debugging and 'debug_options' config line.
1149         - Added 'pid_filename' to configuration file.
1150         - Added 'visible_hostname' to configuration file.
1151         - added 'ftp_user' to configuration file.
1152         - added 'dns_positive_ttl' to configuration file.
1153         - added 'dns_negative_ttl' to configuration file.
1154         - Added 'shutdown_lifetime' to configuration file.
1155         - Fixed bug where cache process would "spin" on large objects
1156           being deferred.
1157         - Fixed byte order conversion bug on setting echo port.
1158         - Changed meaning of command line -b (buffered logs) option.
1159           Now the default behaviour is unbuffered logs, use -b to make
1160           them buffered.
1161         - Changed WAIS code to always be fully compiled in.
1162         - Changed the storage manager to use the notion of private and
1163           public keys.  Requests are now private until the reply headers
1164           have been read.
1165         - Changed access logging significantly.  Entries to "access.log"
1166           are written when the client connection closes.  Every connection
1167           is logged exactly once, always with a valid size.
1168         - Changed access log format (non-common) to include request
1169           method and sub-second timestamps.
1170         - Changed handing of ECONNRESET (connection reset) errors.
1171           Now treated like any other read error.
1172         - Changed 'rotate logs' to be activated by SIGUSR1.
1173         - Changed configure script to look specifically for tm_gmtoff
1174           and set HAVE_TM_GMTOFF.
1175         - Changed configure script to look specifically extended mallinfo
1176           structure and set HAVE_EXT_MALLINFO
1177         - Changed ICP reply code to use negative TTL value as UDP_HIT
1178           threshold so we never return a HIT on neg-cached objects.
1179         - Changed ftpget to use select(2) on I/O for timeouts.  ftpget
1180           now exits immediately if stdin goes away.
1181         - Changed handling of '-z' option.  Now only execute 'rm -rf ...' if
1182           -U option also given.
1183         - Removed the command line -d (debug) option.  Use 'debug_options'
1184           in config file.
1185         - Removed all code and references to binary port.
1186         - Removed dual logging to stderr/cache.log.
1187         - Removed old IP access controls ('proxy_allow', etc.)
