---|---|---|
4c154d99 | 1 | - Added NAT/Transparent hijacking code from Quinton Dolan. |
2 | - Added actual filesystem usage to cachemgr 'storedir' page. | |
3 | Only works for some operating systems. | |
a79d724b | 4 | - Fixed HTCP compile-time bugs. |
5 | - Fixed quick_abort bugs. Configured values are stored as | |
6 | Kbytes, not bytes. | |
0da7d807 | 7 | - Changed storeDirSelectSwapDir() to skip swap directories |
8 | when their utilization is over the high water mark ratio. | |
9ca005ac | 9 | - Fixed off-by-one bug for dead neighbor detection (Joe Ramey). |
18cc143b | 10 | - fixed bugs in Content-Range header generation |
11 | - changed the way Range requests are handled: | |
12 | - do not "advertise" our ability to process ranges at all | |
13 | - on hits, handle simple ranges and forward complex ones | |
14 | - on misses, fetch the whole document for simple ranges | |
15 | and forward range request for complex ranges | |
16 | The change is supposed to decrease the number of cases when clients | |
17 | such as Adobe acrobat reader get confused when we send a "200" | |
18 | response instead of "206" (because we cannot handle complex ranges, | |
19 | even for hits) Note: Support for complex ranges requires storage of | |
20 | partial objects. | |

4c154d99 | 22 | Changes to squid-1.2.beta25 (September 21, 1998): |
23 | ||
4b66bfd3 | 24 | - Fixed async IO bugs from adding filedescriptor arg to AIOCB |
25 | callbacks (Henrik Nordstrom). | |
26 | - Fixed store_swapout.c assertion. We were freeing object data | |
27 | past the swapout_done offset. This probably happens (only?) | |
28 | when an object changes from cachable to uncachable while | |
29 | it is being swapped out. | |
a260d877 | 30 | - Added MEM_CLIENT_SOCK_BUF type so we can change the size |
31 | of the buffers used for writing data to the client sockets. | |
669d90e7 | 32 | - Added configure check for libbind.a. If found, it will be |
33 | used instead of libresolv.a. | |
34 | - Changed fwdStart() to always allow internally generated | |
dddd5b55 | 35 | requests, such as for peer digests. These requests are |
36 | known to fwdStart() because the address arg is set to | |
37 | 'no_addr'. | |
669d90e7 | 38 | - Completed initial HTCP implementation. It works, but is not |
39 | tested much. | |
2d5c8e74 | 40 | - Added counters for I/O syscalls. |
41 | - Fixed httpMaybeRemovePublic. With broken ICP neighbors | |
42 | (netapp) Squid doesn't use private keys. This caused us | |
43 | to remove almost every object from the cache. | |
44 | - Added 'asndb' cachemgr stats to show AS Number tree. | |
dddd5b55 | 45 | - Fixed AS Number byte-order bug for netmasks. |
2d5c8e74 | 46 | - Fixed comm_incoming calling rate for high loads (Stewart |
47 | Forster). | |
426012d2 | 48 | - Give always_direct higher precedence than never_direct |
49 | (Henrik Nordstrom). | |
dddd5b55 | 50 | - Changed PORT ACL type to accept ranges. Now you can easily |
51 | deny, for example, all priveleged ports except 80, 70, 21, | |
52 | etc. | |
53 | - ARP ACL fixes for Linux (David Luyer). | |
54 | - Replaced various "EBIT" flags bitfileds with structures of | |
55 | "int:1" members. | |
56 | - Changed storeKeyPrivate and storeKeyPublic to be a bit more | |
57 | efficient by removing snprintf(). This causes an | |
58 | incompatibility with old cache keys, however. To transition, | |
59 | we will look up both the new and old style keys for about the | |
60 | next 30 days. After that, if you haven't run this (or a | |
61 | future) version, your cache contents will be lost. | |
62 | - Made the client-side write buffer size configurable with | |
63 | a #define in defines.h. By default it is still 4096 bytes. | |
64 | - Removed redirectUnregister(). It should be unnecessary | |
65 | because of cbdata locks. | |
66 | - Fixed multiple HEAD request brokennesses (Henrik Nordstrom). | |
67 | - Changed non-blocking connect(2) code to call getsockopt() | |
68 | instead of connect() again. This is the approach recommended | |
69 | by Stevens, and fixes bugs on BSD-ish systems when subsequent | |
70 | connect() calls loop with EAGAIN status. | |
71 | - Added MD5 cache keys to memory pool accounting. | |
72 | - Added code to track number of open DISK descriptors and stop | |
73 | swapping out objects if the number of disk descriptors becomes | |
74 | too large. For now the limit must be manually configured with | |
75 | the 'max_open_disk_fds'. By default, there is no limit. | |
76 | - Stopped encoding a request method in the high byte of the ICP | |
77 | reqnum field. Instead queried cache keys are copied to a | |
78 | static array, indexed by the reqnum, modulo the array size. | |
79 | Now we just use the request number to lookup a cache key, | |
80 | instead of rebuilding it from the ICP reply URL and method, | |
81 | unless we have netapp neighbors--they don't do reqnum | |
82 | properly. | |
83 | - Fixed reconfigure memory access bugs in redirect.c. | |
4b66bfd3 | 84 | |
8e6a43e8 | 85 | Changes to squid-1.2.beta24 (August 21, 1998): |
86 | ||
6c4067e5 | 87 | - Added Bulgarian error pages by Evgeny Gechev. |
ceb79b2b | 88 | - Changed StoreEntry->lock_count to a u_short. |
c7d6216e | 89 | - Replaced urlcmp with strcmp |
90 | - Fixed pragma no-cache ejecting ENTRY_SPECIAL objects | |
91 | (Henrik Nordstrom). | |
92 | - Eliminated unneeded BASE HREF on "root" directories (Henrik | |
93 | Nordstrom). | |
94 | - Fixed peerDigestFetchFinish() assertion caused by forwarding | |
95 | failures (e.g. miss_access rules). | |
ada249f8 | 96 | - Changed signal handlers with ASYNC_IO and Linux so that |
97 | -k command line options work (Miquel van Smoorenburg). | |
4616f9ea | 98 | - Rewrote shutdown code to use events instead of setting |
99 | FD timeouts. | |
903e21a0 | 100 | - Fixed cachemgr 'objects' (statObjects()) by adding a check |
b6a76fb2 | 101 | for READ_AHEAD_GAP, and calling storeCheckSwapout() in |
102 | storeBufferFlush(). Otherwise, the read-past pages would | |
103 | never be freed. | |
681979a2 | 104 | - Fixed DNSSERVER shutdown bugs. The re-opened dnsserver processes |
105 | were being closed by the dnsServerShutdown event. | |
b6a76fb2 | 106 | - Modified storeHashInsert() to insert PRIVATE objects at |
107 | the tail of the LRU list, and PUBLIC objects at the head. | |
108 | Thus, PRIVATE objects get kicked out quicker. | |
95e36d02 | 109 | - Added David Luyer's DELAY_POOLS code. |
54b5b3e5 | 110 | - Fixed a bug due to HEAD replies which lack the end-of-headers |
111 | line. | |
112 | - Made proxy-auth realm string configurable (Bob Franklin) | |
113 | - Changed default mime time to a viewable one (Henrik Nordstrom). | |
114 | - configure fixes for Sony's NEWS-OS 6.x (Makoto MATSUSHITA). | |
115 | - Fixed 'you are running out of filedescriptors' bug which | |
116 | could cause the HTTP incoming connection handler to not | |
117 | be reset. | |
e23fbf04 | 118 | - Changed syslog logging. Now squid debug levels 0 and 1 go |
d737baa0 | 119 | to syslog. Level 0 gets LOG_WARNING and level 1 gets LOG_NOTICE |
e23fbf04 | 120 | (this needs more work!) |
2cb51fe0 | 121 | - Fixed memory access errors in statAvgTick(). |
abc1237e | 122 | - Fixed duplicate requestUnlink() bug in forward.c |
6c4067e5 | 123 | - Fixed possible memory access bugs from not setting e->mem_obj |
124 | = NULL in destroy_MemObject(). | |
125 | - Deleted TCP_IMS_MISS tag. Always use TCP_IMS_HIT instead. | |
126 | - Modified headersEnd and httpMsgIsolateHeaders to account | |
127 | for funky line terminations such as CRCRNL. | |
128 | (``but Netscape and IE _tolerate_ this'') | |
129 | - Fixed carp functions (Eric Stern). | |
130 | - Replaced internal proxy_auth code with extern authentication | |
131 | module (Arjan de Vet). | |
132 | - moved hash.c to libmiscutil.a. | |
e931f99a | 133 | - Fixed handling of ICP queries with whitespace in URLs. |
134 | Now we return ICP error and escape the URL before logging. | |
3a15a393 | 135 | - Added configure check for socklen_t (David Luyer). |
136 | - Removed USE_SPLAY #defines; it is now standard. | |
3a76c002 | 137 | - Added FD arg to async IO callbacks (AIOCB) so we can eliminate |
138 | temporary disk_ctrl_t structures. | |
139 | - Changed ENOSPC disk write errors to reduce specific cache_dir | |
140 | sizes, and not just the size of the cache as a whole. | |
f9cece6e | 141 | - Added httpMaybeRemovePublic() to purge public objects for |
142 | certain responses even though they are uncachable. This is | |
143 | needed, for example, when an initially cachable object | |
144 | later becomes uncachable. | |
8e6a43e8 | 145 | - Added refresh_pattern options to ignore client reloads |
146 | (Henrik Nordstrom) | |
147 | - Relocated disk.c code which combines blocks for writing | |
148 | (Stewart Forster). | |
c7d6216e | 149 | |
857703c6 | 150 | Changes to squid-1.2.beta23 (June 22, 1998): |
151 | ||
cf7f704c | 152 | - Added Turkish error pages by Tural KAPTAN. |
66bbb757 | 153 | - Added basic support for Range requests. For most cachable |
154 | requests, Squid replies with an "Accept-Ranges" header. Upon | |
155 | receiving a potentially cachable Range request for a not | |
156 | cached object, Squid requests the whole object from origin | |
157 | server and then replies with specified range(s) to the | |
158 | client. Multi-range requests are supported. Adjacent | |
159 | overlapping ranges are merged. If-Range requests are | |
160 | supported. Limitations: Multi-range requests with out of | |
161 | order ranges are not supported. | |
162 | - Made md5.c use standard memcpy and memset if they are | |
163 | avaliable. | |
164 | - Memory pools will now shrink if Squid is run-time | |
165 | reconfigured with smaller value of memory_pools_limit tag. | |
166 | - Added counter for number of clients (Tomi Hakala). | |
167 | - Changed neighbor UP/DOWN algorithm to require 10 failed TCP | |
168 | connections for UP->DOWN transition. | |
169 | - Added 'unique_hostname' configuration option when its | |
170 | necessary to have multiple machines with the same visible | |
171 | hostname. | |
222917b2 | 172 | - Fixed pumpReadFromClient() to not read too many bytes on |
173 | persistent connections. | |
53856ebd | 174 | - We can now cache HTTP replies with Set-Cookie. These evil |
175 | headers are now filtered out for cache hits on the client | |
176 | side. | |
222917b2 | 177 | - Fixed SNMP bugs caused by using snmpwalk. |
9089cc70 | 178 | - Fixed snmp system Group; all objects are now returned. |
179 | - Fixed snmp system Group sysDescr and sysContact. | |
78dfab2a | 180 | - Fixed snmp system Group sysObjectID it now returns a OBJECT |
181 | IDENTIFIER. | |
7fce9c3e | 182 | - Allocate FwdState from mem pools. |
183 | - Minor HTCP progress. | |
222917b2 | 184 | - Moved 'miss_access' ACL check from client_side.c to forward.c |
ed169eab | 185 | - Fixed logging of usernames for requests which require |
186 | proxy-authentication. | |
cf7f704c | 187 | - Fixed HTTP request parser to accept lowercase HTTP identifier |
188 | (Oskar Pearson). | |
189 | - Fixed FTP listings to always include links to the parent | |
190 | directory (Henrik Nordstrom). | |
191 | - Fixed FTP to show an "empty" listing instead of showing | |
192 | a "document contains no data" error (Henrik Nordstrom). | |
193 | - Fixed refreshCheck() bug. Often it was checking the | |
194 | refresh patterns against the string "[null_mem_obj]" | |
195 | because we moved URLs to MemObject. | |
196 | - Added CARP support by Eric Stern. | |
48382032 | 197 | - Fixed select-spin bug when an ICP reply actually gets queued |
198 | and we failed to execute the write callback. | |
354b5fe1 | 199 | - Fixed a storeCheckSwapOut bug. We were freeing up to |
200 | the queued offset instead of the done offset. This | |
201 | resulted in a small chunk of object data not being in | |
202 | memory and not yet written to disk. A client could | |
203 | recieve a partial object because file_read() unexpectedly | |
204 | returns EOF. | |
0aa791f8 | 205 | - Fixed proxy-authentication hangs (Henrik Nordstrom). |
c2354a6b | 206 | - Fixed request_t->flags bug causing authenticated, proxied |
207 | responses to be cached (Arjan de Vet). | |
e0e32f36 | 208 | - Fixed MIME types for .tgz extension (Henrik Nordstrom). |
209 | - Added view and download options to FTP listings (Henrik | |
210 | Nordstrom). | |
211 | - Modified configure to allow using pre-installed libdlmalloc.a | |
212 | (Masashi Fujita). | |
e8d8856c | 213 | - Fixed cachemgr 'objects' implementation. |
fecf98dc | 214 | - Changed refreshCheck() algorithm. For cached objects, we |
215 | now check, in the following order: | |
216 | * request max-age | |
217 | * response Expires (if present) | |
218 | * refresh_pattern max-age | |
219 | * response Last-Modified compared to refresh_pattern | |
220 | LM-factor (only if Last-Modified is present) | |
221 | * refresh_pattern min-age | |
222 | - Changed Copyrights. | |
d192d11f | 223 | |
ee3a78d4 | 224 | Changes to squid-1.2.beta22 (June 1, 1998): |
225 | ||
2246b732 | 226 | - do not cut off "; parameter" from "digitized" Content-Type |
227 | http fields | |
228 | - Added X-Request-URI for persistent connection debugging | |
229 | (Henrik Nordstrom) | |
f4d83f6d | 230 | - Added Polish error pages from Maciej Kozinski. |
145f10f1 | 231 | - Fixed hash_first/hash_next bugs with **Current pointer. |
232 | Replaced with *next pointer. | |
f4d83f6d | 233 | - Fixed PUT/POST bugs in client (Henrik Nordstrom). |
234 | - Deny forwarding loops in httpd accel mode (Henrik Nordstrom). | |
235 | - Fixed eventRun "spin" bug when event delta time == 0. | |
a9cc1935 | 236 | - Fixed setting Last Modified time on cached entries when |
237 | receiving a 304 reply. | |
06e87923 | 238 | - Added while loop in httpAccept(). |
239 | - Added while loop in icpHandleUdp(). | |
240 | - Fixed some small memory leaks. | |
241 | - Fixed single-bit-int flag checks (Henrik Nordstrom). | |
137ee196 | 242 | - Replaced "complex" (offset accounting) calls to snprintf with MemBuf |
243 | - Do not send only-if-cached cc directive with requests | |
244 | for peer's digests. | |
ee3a78d4 | 245 | - Added "automatic tuning" for incoming request rate, i.e. |
246 | how often to check HTTP and ICP sockets. See comm.c | |
247 | comments for details. | |
145f10f1 | 248 | |
6ee40ea2 | 249 | Changes to squid-1.2.beta21 (May 22, 1998): |
250 | ||

a3f9588e | 252 | - Added Estonian error pages by Toomas Soome. |
06066bbc | 253 | - Added Russian (koi-r) error pages by Andrew L. Davydov. |
7b381d33 | 254 | - Added Czech error pages by Jakub Nantl. |
8e866bb4 | 255 | - Fixed asnAclInitialize calling to prevent coredump. |
256 | - Fixed FTP directory parsing again. | |
257 | - Made FTP directory listing "Generated" tagline like | |
258 | the one for error pages. | |
52f977aa | 259 | - Fixed an assertion coredump in statHistCopy from |
260 | reconfiguring with different #peers in squid.conf | |
10202788 | 261 | - Ignore leading whitespace on requests (and replies). RFC |
262 | 2068 section 4.1, robustness (Henrik Nordstrom) | |
263 | - Fixed keep_alive bug. We did not always honour reply | |
264 | headers, but rather assumed connections could be persistent. | |
265 | - Fixed reading whois output for AS numbers, especially when | |
266 | they are longer than 4 KB. | |
267 | - Removed 'cache_stoplist_pattern' configuration option. This | |
268 | feature is now handled by 'no_cache'. | |
269 | - If a URN resolves to only one URL, just return it immediately | |
270 | instead of giving the user a "choice" (Andy Powell). | |
271 | - Fixed year-2000 bug in lib/iso3307.c (Henrik Nordstrom). | |
272 | - Changed squid-internal object names. | |
273 | - Added netdb exchange protocol. | |
274 | - Fixed wordlistDestroy() uninitialized pointer bug in | |
275 | ftpParseControlReply. | |
06066bbc | 276 | - Fixed redirector subprocess to show real program name. |
277 | - Changed URN menu output to be sorted. | |
278 | - Added fast select(2) timeouts when using ASYNC_IO. | |
279 | - Added ARP ACL support for Linux (David Luyer). | |
2246b732 | 280 | - Added binary http headers to requests |
99edd1c3 | 281 | - request_t objects are now created and destroyed in a consistent way |
282 | - Fixed cache control printf bug | |
283 | - Added a lot of new http header ids | |
284 | - Improved Connection: header handling; now both Connection and | |
2246b732 | 285 | Proxy-Connection headers are checked for connection directives |
99edd1c3 | 286 | - Connection request header is now handled correctly regardless |
287 | of its position and the number of entries | |
2246b732 | 288 | - Only replies with valid Content-Length can be sent with keep-alive |
289 | connection directive (Henrik Nordstrom) | |
290 | - Better handling of persistent connection "clues" in HTTP headers; | |
291 | the decision now depends on HTTP version (and User-Agent exceptions) | |
99edd1c3 | 292 | - Removed handling of "length=" directive in IMS headers; |
293 | the directive is not in the HTTP/1.1 standard; | |
294 | standing by for objections | |
295 | - allowed/denied headers are now checked using bit masks instead of | |
296 | strcmp loops | |
297 | - removed Uri: from allowed headers; Uri is deprecated in RFC 2068 | |
2246b732 | 298 | - removed processing of Request-Range header (not in specs?) |
7b381d33 | 299 | - Fixed byte-order bugs in cacheDigestHashKey. |
300 | - Changed hash_remove_link() to return void. | |
301 | - Changed ipcache_gethostbyname() to return NULL if | |
302 | i->addrs.count == 0. | |
6de5fa88 | 303 | - Added millisecond-timing to select/poll loops and event |
304 | queue. | |
305 | - Changed 'peerPingTimeout' value to be twice the average | |
306 | of all the peer ICP RTT's. | |
307 | - Added 'half_closed_clients' option to force closing of | |
308 | client connections which might only be half-closed. | |
309 | - Fixed matchDomainName coredump bug. | |
310 | - Don't cache HTTP replies with Vary: headers until we | |
311 | get content negotiation working. | |
312 | - Fixed SSL proxying to forward full HTTP request headers. | |
c09459dd | 313 | - Changed storeGetMemSpace(). Only purge down to the HIGH |
314 | water mark; move locked entries to the head of the inmem | |
315 | list. | |
316 | - Changed clientReadRequest() to locally handle any | |
317 | "squid-internal-static" URL for any host. | |
52f977aa | 318 | - Disable persistent connections for client connections |
319 | from broken Netscape User-Agent, version 3.* (Stewart Forster) | |
434b408f | 320 | |
901b8eaf | 321 | Changes to squid-1.2.beta20 (April 24, 1998): |
322 | ||
fd1bc012 | 323 | - Improved support for only-if-cached cache control directive. |
324 | - Enabled 304 replies for ENTRY_SPECIAL objects (e.g., icons). | |
a1a62b14 | 325 | - Fixed 'quick_abort' percent calculation bug. |
326 | - Fixed quick_abort FPE bug. | |
327 | - Changed more errno-checking functions to use ignoreErrno(). | |
328 | - Added ERESTART to ignoreErrno() because of report from | |
329 | a Solaris system. | |
330 | - Fixed '#elsif' typo. | |
331 | - Fixed MemPool assertion by moving memInit() to before | |
332 | configuration parsing functions. | |
333 | - Fixed default 'announce_period' value (was 1 day, should | |
334 | be 0) (Joe Ramey). | |
335 | - Added configure warning for low filedescriptors and pointer | |
336 | to FAQ. | |
b0497a40 | 337 | - Fixed httpBodySet() bug causing URN related coredumps. |
338 | - Changed ipcacheCycleAddr() to always cycle through all all | |
339 | available addresses, and not just advance when one of | |
340 | them goes BAD. | |
341 | - Fixed squid-internal bug for mixed-case hostnames (Henrik | |
342 | Nordstrom). | |
4e41d49f | 343 | - Fixed ICP counting probelm. icpUdpSend() arg should be |
344 | LOG_ICP_QUERY instead of LOG_TAG_NONE. | |
e4b71f74 | 345 | - Added some additional fault toleranse on FTP data channels |
346 | (Henrik Nordstrom). | |
347 | - Corrected error reporting on FTP "hacks" (Henrik Nordstrom). | |
348 | - Added lock/unlock for StoreEntry during storeAbort(). | |
349 | - Added filemap bit usage stats to cachemgr 'storedir' and | |
350 | 'info'. | |
351 | - Replaced 'cache_stoplist' with 'no_cache' Access list. | |
352 | - Fixed (hopefully) remaining swapfile-open-at-exit bugs. | |
44745828 | 353 | - Fixed default hierarchy_stoplist to be ``default if none.'' |
354 | - Fixed 'fake a recent reply' hack for detecting DEAD | |
355 | and ALIVE neighbors (Joe Ramey). | |
e376562a | 356 | - Fixed FTP directory parsing bugs (Joe Ramey). |
357 | - Fixed ftpTraverseDirectory coredump for NULL ftpState->filepath | |
358 | (Joe Ramey). | |
dea17509 | 359 | - Fixed daylight savings time bug (again). |
fd1bc012 | 360 | - A lot of Cache Digests additions, fixes, and tuning. |
361 | Cache Digests are still "very experimental". | |
e376562a | 362 | - Fixed snprintf() bug. When len == 1, snprintf() would treat |
363 | the buffer as unknown size, emulating sprintf() behaviour. | |
364 | - Made Error page language configurable with configure script | |
365 | (Henrik Nordstrom). | |
366 | - Fixed squid-internal URLs when http_port == 80. | |
367 | - Remember the client address on redirected requests (Henrik | |
368 | Nordstrom). | |
369 | - Don't rebuild the request if the redirector returned the same | |
370 | URL (Henrik Nordstrom). | |
371 | - Rewrite Host: header on redirected requests (Henrik | |
372 | Nordstrom). | |
373 | - Include port (if non-standard) in generated Host: headers | |
374 | (Henrik Nordstrom). | |
375 | - Fixed rfc1123 timezone hacks for Windows NT | |
376 | (Henrik Nordstrom). | |
377 | - Added Russian Error pages by Ilia Zadorozhko. | |
378 | - Added totals for ICP and HTTP hits to cachemgr client_list | |
379 | output. | |
6cfa8966 | 380 | - Changed error message to 'Generated TIME by HOST (SQUID/VER)' |
381 | because any string with an '@' must be an email address. | |
e376562a | 382 | - Fixed POST for content-length == 0. |
901b8eaf | 383 | - Fixed "huge 304 reply" loop bug. |
5e9ab945 | 384 | - Fixed --enable-splaytree compile bugs. |
c93fbf13 | 385 | - Removed ASN lookup code in peer_select.c. |
fd1bc012 | 386 | |
005e5260 | 387 | Changes to squid-1.2.beta19 (Apr 8, 1998): |
388 | ||
b0497a40 | 389 | - Squid-1.2.beta19 compiles and runs on Windows/NT with |
390 | Cygnus Gnu-WIN32 b19 (Henrik Nordstrom). | |
447203a7 | 391 | - Added French Error pages by Frank DENIS. |
392 | - Added Dutch Error pages by Mark Visser | |
901b8eaf | 393 | - Added German Error pages by Bernd P. Ziller, Jens Frank, |
394 | and Anke S. | |
f9f2be04 | 395 | - Added support for only-if-cached cache-control directive. |
005e5260 | 396 | - Added RELAXED_HTTP_PARSER #define to allow requests which are |
397 | missing the HTTP identifier on the request line (e.g. buggy | |
398 | SpyGame queries). RELAXED_HTTP_PARSER is undefined by default. | |
1f4d31f9 | 399 | - Fixed disk.c FD leak for delayed closes in |
400 | diskHandleWriteComplete(). | |
401 | - Fixed cache announcement feature. | |
20fe7191 | 402 | - Fixed httpReadReply() to retry failed HTTP requests on |
403 | persistent connections when read() returns -1, not only | |
404 | when it returns 0. | |
805e5f70 | 405 | - Fixed cbdata memory counting leak. cbdataUnlock() always |
406 | called free(), never memFree(). | |
ff396fe6 | 407 | - Fixed storeDirWriteCleanLogs() malloc bug on Alphas. |
005e5260 | 408 | - Fixed `++loopdetect < 10' assertion due to |
409 | clientHandleIMSReply bug for invalid/partial HTTP | |
410 | replies. | |
411 | - Added preliminary code for HTCP. | |
412 | - Renamed 'aux' dir to 'cfgaux' for legacy DOS machines. | |
413 | - Added "snmp_community" as an ACL type. | |
414 | - Cleaned up proxy-auth acl implementation and removed | |
415 | memory leaks. | |
416 | - Added generic 'hashFreeItems()' function for efficiently | |
417 | freeing hash table pointers. | |
418 | - Added whoisTimeout() for ASN code. | |
447203a7 | 419 | - Removed BINARY TREE code. |
005e5260 | 420 | - Fixed forgetting to reset Config.Swap.maxSize in |
421 | configDoConfigure. | |
422 | - Fixed httpReplyUpdateOnNotModified() arguments-in-wrong-order | |
423 | bug which caused not modified replies to not get updated. | |
424 | - Fixed client_side.c bugs which could cause data to be written | |
425 | to the client in the wrong order for persistent connections. | |
426 | clientPurgeRequest() and clientHandleIMSComplete() must not | |
427 | call comm_write(). Instead they must create and write to | |
428 | StoreEntry's. | |
429 | - Fixed ICP query service time counting bug(s). | |
430 | - replaced 'char *mime_headers_end()' with 'size_t headersEnd()' | |
431 | to fix buffer overruns. This also requires adding 'buf_sz' | |
432 | args to some functions like clientBuildReplyHeader(). | |
433 | But we can eliminate the need to NULL-terminate the | |
434 | buffer beforehand. | |
435 | - Changed commConnectCallback() to reset the FD timeout to | |
436 | zero before notifying about the connection. This requires | |
437 | commSetTimeout() calls in numerous places to reinstall | |
438 | timeouts. | |
439 | - Changed comm_poll_incoming() to be called less frequently | |
440 | (every 15 I/O's instead of every 7 FD's) (Michael O'Reilly). | |
441 | - Removed HAVE_SYSLOG case for debug() macro. Almost all | |
442 | systems do have syslog(), but more importatnly the | |
443 | _db_level value is needed for debugging to stderr. | |
444 | - Rewrote squid/dnsserver interface to use smaller, single-line | |
445 | messages. | |
446 | - Rewrote 'dns' cachemgr output to use a table format. | |
447 | - Rewrote a lot of dnsserver.c. | |
448 | - Added eventAddIsh() for semi-random event scheduling. | |
449 | - Fixed an ftpTimeout bug for sessions which use PORT | |
450 | commands. | |
451 | - Fixed ftp.c to recognized invalid PASV replies (e.g. | |
452 | port == 0). | |
453 | - Removed hash_insert(). All hasing uses hash_join() now. | |
454 | - Renamed hash_unlink() to hash_remove_link(). | |
455 | - Added hashPrime() to find closes prime hash table size | |
456 | to a given value. | |
457 | - Fixed Keep-Alive ratio counting bug which prevented | |
458 | persistent connections from being used between cache | |
459 | peers. | |
460 | - Changed icmp.c to NOT queue messages sent from squid to | |
461 | the pinger program. | |
462 | - Changed icp_v2.c to NOT queue ICP messages by default. | |
463 | But they will be queued and resent once if the first | |
464 | send fails. Counters.icp.queued_replies counts the | |
465 | number of messaages queued. | |
466 | - Cleaned up ICP logging. | |
467 | - Added identTimeout(). | |
468 | - Fixed ipcache reply counting bug. Overcounted dnsserver | |
469 | replies for partial replies. | |
470 | - Added urlInternal() for building internal Squid URLs. | |
471 | - Changed peerAllowedToUse() to check both 'cache_peer_domain' | |
472 | AND 'cache_peer_acl' configurations. This should be changed | |
473 | in the fugure to use ONLY cache_peer_acl. | |
474 | - Changed DEAD/REVIVED neighbor detection to avoid reporting | |
475 | so many false deaths. (Joe Ramey). | |
476 | - Added some preliminary code to support "cache digests." | |
477 | - Fixed pumpClose() coredumps (?). | |
478 | - Updated cachemgr 'info' output to show median service | |
479 | times for various categories. | |
480 | - Fixed ABW bug in storeDirWriteCleanLogs(). sizeof(off_t) | |
481 | != sizeof(int) for Alphas. | |
482 | - Fixed potential alignment problem in storeDirWriteCleanLogs(). | |
483 | - Fixed store_rebuild.c to NOT replace current, but | |
484 | not-swapped-out StoreEntry's with on-disk entries. | |
485 | - Changed storeCleanup() to call storeRelease on invalid | |
486 | entries which don't have a swapfile (i.e. no unlink() | |
487 | penalty). | |
488 | - Fixed storeSwapInStart() to fail for unvalidated | |
489 | entries. | |
490 | - SNMP changes: | |
491 | . renovated mib and added descriptions and comments | |
492 | . added hit and byte counters to client_db , for | |
493 | cacheClientTable | |
494 | . cacheClientTable, netdbTable, cachePeerTable, | |
495 | cacheConnTable now indexed by ip address. hash_lookup was | |
496 | enhanced to allow for subsequent hash_next's similar to | |
497 | hash_first, to speed up getnext's in tables which refer to | |
498 | hash-table structures. | |
499 | . added generic (well, sorf of) table indexing functionality | |
500 | . added makefile dependencies for snmplib and cache_snmp.h | |
501 | . WaisHost, WaisPort, Timeouts removed | |
502 | . FdTable split into FdTable and ConnTable. FdTable simplified | |
503 | . PeerTable and PeerStat merged and put into new cacheMesh | |
504 | group | |
505 | . cacheClientTable added for client statistics and accounting | |
506 | (cacheMesh 2) | |
507 | . cacheSec and cacheAccounting groups removed | |
508 | . fixed acl bug when communities not defined | |
509 | . snmp_acl now survives bad configuration | |
81d0c856 | 510 | |
9a713ffb | 511 | Changes to squid-1.2.beta18 (Mar 23, 1998): |
512 | ||
275d9f2e | 513 | - Added v1.1 'test_reachability' option. |
514 | - Fixed hash4() len == 0 bug. | |
2c26197b | 515 | - Fixed Config.Swap.maxSize reconfigure bug. |
516 | - Fixed ICP query bug determining request method. | |
517 | - Moved ICP's storeGet() cache lookup into neighborsUdpAck() | |
518 | so that we know neighbors are alive even when they send | |
519 | us replies for unknown entries. | |
520 | - Changed configure script to add '-std1' for Digital Unix cc. | |
521 | - Fixed SNMP sizeof(int) / sizeof(long) bugs for 64-bit | |
522 | systems. | |
523 | - Added support for 'Cache-Control: Only-If-Cached' request header. | |
34ad1721 | 524 | - Fixed CheckQuickAbort() bugs for multiple clients on one |
525 | StoreEntry. Also changed storePendingNClients() to return | |
526 | mem->nclients instead of counting the number of store_client | |
527 | entries with pending callback functions. | |
275d9f2e | 528 | |
041b157e | 529 | Changes to squid-1.2.beta17 (Mar 17, 1998): |
530 | ||
df43fc93 | 531 | - SNMP MIB version check changed to non-rcs. |
02922e76 | 532 | - Added memory pools for variable size objects (strings). |
533 | There are three pools; for small, medium, and large objects. | |
534 | - Extended String object to use memory pools. Most fixed size char | |
535 | array fields will be replaced using string pools. Same for most | |
536 | malloc()-ed buffers. | |
5e14bf6d | 537 | - Changed icon handling to use the hostname and port of the squid |
9ed90c85 | 538 | server, instead of the special hostname "internal.squid" |
539 | (Henrik Nordstrom). | |
5e14bf6d | 540 | - All icons are now configured in mime.conf. No hardcoded icons, |
f8360ee3 | 541 | including gohper icons (Henrik Nordstrom). |
459f2559 | 542 | - Fixed ICP bug when we send queries, but expect zero |
543 | replies. | |
ed9c0b33 | 544 | - Fixed alignment/casting bugs for ICP messages. |
2b5b6324 | 545 | - A generic client-to-server "pump" was added to handle HTTP |
546 | PUT as well as POST methods on the client-cache side. Based on | |
547 | "pump" PUT requests can be made to either HTTP or FTP url's. | |
548 | Code is still beta and interoperability with browsers etc has | |
549 | not been tested. | |
550 | - Put #ifdefs around 'source_ping' code. | |
5e14bf6d | 551 | - Added missing typedef for _arp_ip_data (Wesha). |
552 | - Added regular-expression-based ACLs for client and server | |
553 | domain names (Henrik Nordstrom). | |
554 | - Fixed ident-related coredumps from incorrect callback data. | |
555 | - Fixed parse_rfc1123() "space" bug. | |
556 | - Fixed xrealloc() XMALLOC_DEBUG bug (not calling check_free()).. | |
557 | - Fixed some src/asn.c end-of-reply bugs and memory leaks. | |
558 | - Fixed some peer->options flag-setting bugs. | |
559 | - Fixed single-parent feature to work again | |
560 | - Removed 'single_parent_bypass' configuration option; instead | |
561 | just use 'no-query'. | |
562 | - Surrounded 'source_ping' code with #ifdefs. | |
563 | - Changed 'deny_info URL' to use a custom Error page. | |
564 | - Modified src/client.c for testing POST requests. | |
041b157e | 565 | - Fixed hash4() for SCO (Vlado Potisk). |
459f2559 | 566 | |
7ba777f2 | 567 | Changes to squid-1.2.beta16 (Mar 4, 1998): |
568 | ||
447203a7 | 569 | - Added Spanish error messages from Javier Puche. |
02922e76 | 570 | - Added Portuguese error messages from Pedro Lineu Orso |
0965bd19 | 571 | - Added a simple but very effective hack to cachemgr.cgi that tries to |
572 | interpret lines with '\t' as table records and formats them | |
573 | accordingly. With a few exceptions (see source code), first line | |
574 | becomes a table heading ("<th>" html tag) and the rest is formated | |
575 | with "<td>" tags. | |
7021844c | 576 | - Added "mem_pools_limit" configuration option. Semantics of |
577 | "mem_pools" option has also changed a bit to reflect new memory | |
578 | management policy. | |
7ba777f2 | 579 | - Reorganized memory pools. Squid now supports a global pool |
580 | limit instead of individual pool limits. Per-pool limits can be | |
3a88d597 | 581 | implemented on top of the current scheme if needed, but it is |
7ba777f2 | 582 | probably hard to guess their values. Squid distributes pool |
583 | memory among "frequently allocated" objects. There is a | |
584 | configurable limit on the total amount of "idle" memory to be | |
585 | kept in reserve. All requests that exceed that amount are | |
586 | satisfied using malloc library. Support for variable size | |
587 | objects (mostly strings) will be enabled soon. | |
588 | - memAllocate() has now only one parameter. Objects are always | |
589 | reset with 0s. (We actually never used that parameter before; | |
590 | it was always set to "clear"). | |
591 | - Added Squid "signature" to all ERR_ pages. The signature is | |
592 | hardcoded and is added on-the-fly. The signature may use | |
593 | %-escapes. Added interface to add more hard-coded responses if | |
594 | needed (see errorpage.c::error_hard_text). | |
595 | - Both default and configured directories are searched for ERR_ | |
596 | pages now. Configured directory is, of course, searched first. | |
597 | This allows you to customize a subset of ERR_ pages (in a | |
598 | separate directory) without danger of getting other copies out | |
599 | of sync. | |
600 | - Security controls for the SNMP agent added. Besides | |
601 | communities (like password) and views (part of tree | |
602 | accessible), the snmp_acl config option can be used to do acl | |
603 | based access checks per community. | |
604 | - SNMP agent was heavily re-written, based on cmu-snmpV1.8. You | |
605 | can now walk through the whole mib tree. Several new variables | |
606 | added under cacheProtoAggregateStats | |
12cf1be2 | 607 | - Added rudimental statistics for HTTP headers. |
7ba777f2 | 608 | - Adjusted StatLogHist to a more generic/flexible StatHist. |
12cf1be2 | 609 | Moved StatHist implementation into a separate file. |
178dbda2 | 610 | - Added FTP support for PORT if PASV fails, also try the |
611 | default FTP data port (Henrik Nordstrom). | |
612 | - Fixed NULL pointer bug in clientGetHeadersForIMS when a | |
613 | request is cancelled for fails on the client side. | |
614 | - Filled in some squid.conf comments (never_direct, | |
615 | always_direct). | |
616 | - Added RES_DNSRCH to dnsserver's _res.options when the | |
617 | -D command line option is given. | |
618 | - Fixed repeated Detected DEAD/REVIVED Sibling messages when | |
619 | peer->tcp_up == 0 (Michael O'Reilly). | |
620 | - Fixed storeGetNextFile's incorrect "directory does not exist" | |
621 | errors (Michael O'Reilly). | |
622 | - Fixed aiops.c race condition (Michael O'Reilly, Stewart | |
623 | Forster). | |
624 | - Added 'dns_nameservers' config option to specify non-default | |
625 | DNS nameserver addresses (Maxim Krasnyansky). | |
626 | - Added lib/util.c code to show memory map as a tree | |
627 | (Henrik Nordstrom). | |
628 | - Added HTTP and ICP median service times to Counters and | |
629 | cachemgr average stats. | |
630 | - Changed "-d" command line option to take debugging level | |
631 | as argument. Debugging equal-to or less-than the argument | |
632 | will be written to stderr. | |
ef65d6ca | 633 | - Removed unused urlClean() function from url.c. |
adba4a64 | 634 | - Fixed a bug that allowed '?' parts of urls to be recorded in |
ef65d6ca | 635 | store.log. Logged urls are now "clean". |
178dbda2 | 636 | - Cache Manager got new Web interface (cachemgr.cgi). New .cgi |
637 | script forwards basic authentication from browser to squid. | |
638 | Authentication info is encoded within all dynamically generated | |
639 | pages so you do not have to type your password often. | |
640 | Authentication records expire after 3 hours (default) since | |
641 | last use. Cachemgr.cgi now recognizes "action protection" types | |
642 | described below. | |
643 | - Added better recognition of available protection for actions | |
644 | in Cache Manager. Actions are classified as "public" (no | |
645 | password needed), "protected" (must specify a valid password), | |
646 | "disabled" (those with a "disable" password in squid.conf), and | |
647 | "hidden" (actions that require a password, but do not have | |
648 | corresponding cachemgr_passwd entry). If you manage to request | |
649 | a hidden, disabled, or unknown action, squid replies with | |
650 | "Invalid URL" message. If a password is needed, and you failed | |
651 | to provide one, squid replies with "Access Denied" message and | |
652 | asks you to authenticate yourself. | |
653 | - Added "basic" authentication scheme for the Cache Manager. | |
654 | When a password protected function is accessed, Squid sends an | |
655 | HTTP_UNAUTHORIZED reply allowing the client to authorize itself | |
656 | by specifying "name" and "password" for the specified action. | |
657 | The user name is currently used for logging purposes only. The | |
658 | password must be an appropriate "cachemgr_passwd" entry from | |
659 | squid.conf. The old interface (appending @password to the url) | |
660 | is still supported but discouraged. Note: it is not possible | |
661 | to pass authentication information between squid and browser | |
662 | *via a web server*. The server will strip all authentication | |
663 | headers coming from the browser. A similar problem exists for | |
664 | Proxy-Authentication scheme. | |
665 | - Added ERR_CACHE_MGR_ACCESS_DENIED page to notify of | |
666 | authentication failures when accessing Cache Manager. | |
63259c34 | 667 | - Added "-v" (Verbose) and "-H" (extra Headers) options to client.c. |
178dbda2 | 668 | - Added simple context-based debugging to debug.c. Currently, |
669 | the context is defined as a constant string. Context reporting | |
670 | is triggered by debug() calls. Context debugging routines | |
671 | print minimal amount of information sufficient to describe | |
672 | current context. The interface will be enhanced in the future. | |
673 | - Replaced _http_reply with HttpReply. HttpReply is a | |
674 | stand-alone object that is responsible for parsing, swapping, | |
675 | and comm_writing of HTTP replies. Moved these functions from | |
676 | various modules into HttpReply module. | |
8bfcd557 | 677 | - Added HttpStatusLine, HttpHeader, HttpBody. |
178dbda2 | 678 | - All HTTP headers are now parsed and stored in a "compiled" |
679 | form in the HttpHeader object. This allows for a great | |
680 | flexibility in header processing and builds basis for support | |
681 | of yet unsupported HTTP headers. | |
682 | - Added Packer, a memory/store redirector with a printf | |
683 | interface. Packer allows to comm_write() or swap() an object | |
684 | using a single routine. | |
685 | - Added MemBuf, a auto-growing memory buffer with printf | |
686 | capabilities. MemBuf replaces most of old local buffers for | |
687 | compiling text messages. | |
688 | - Added MemPool that maintains a pre-allocated pool of opaque | |
689 | objects. Used to eliminate memory thrashing when allocating | |
690 | small objects (e.g. field-names and field-value in http | |
691 | headers). | |
8bfcd557 | 692 | |
3197e644 | 693 | Changes to squid-1.2.beta15 (Feb 13, 1998): |
694 | ||
55647891 | 695 | NOTE: This version has changes which may cause all or part |
696 | of your cache to be lost. However, you can problably | |
697 | save most of it by doing a slow restart. Specifically: | |
698 | ||
699 | 1. Kill the running squid-1.2.beta14 process; wait for it to | |
700 | fully exit. | |
701 | 2. Remove all 'swap.state*' files, either in each cache_dir, or | |
702 | as defined in your squid.conf | |
703 | 3. Start squid-1.2.beta15. The store will be rebuilt from the | |
704 | existing swap files, reading the directories and opening | |
705 | the files. | |
706 | ||
bcfbdc11 | 707 | - Fixed some problems related to disk (and pipe) write error |
708 | handling. file_close() doesn't always close the file | |
709 | immediately; i.e. when there are pending buffers to write. | |
710 | StoreEntry->lock_count could become zero while a write is | |
711 | pending, then bad things happen during the callback. | |
712 | - The file_write() callback data must now be in the callback | |
713 | database (cbdata). We now use the swapout_ctrl_t structure | |
714 | for the callback data; it stays around for as long as we are | |
715 | swapping out. | |
716 | - Changed the way write errors are handled by diskHandleWrite. | |
717 | If there is no callback function, now we exit with a fatal | |
718 | message under the assumption that the file in question is a | |
719 | log file or IPC pipe. Otherwise, we flush all the pending | |
720 | write buffers (so we don't see multiple repeated write errors | |
721 | from the same descriptor) and let the upper layer decide how | |
722 | to handle the failure. | |
723 | - Fixed storeDirWriteCleanLogs. A write failure was leaving | |
724 | some empty swap.state files, even though it tells us that its | |
725 | "not replacing the file." Don't flush/rename logs which we | |
726 | have prematurely closed due to write failures, indiciated by | |
727 | fd[dirn] == -1. Close these files LAST, not before | |
728 | renaming. | |
729 | - Fixed storeDirClean to clean directories in a more sensible | |
730 | order, instead of the new "MONOTONIC" order for swap files. | |
0465e406 | 731 | - Merged fdstat.c functions into fd.c. |
732 | - Cleaned up some debugging sections. Some unrelated source | |
733 | files were using the same section. | |
734 | - Removed curly brackets from all cachemgr output. | |
735 | - Removed unused filemap->last_file_number_allocated member. | |
736 | - Removed unused fde->lifetime_data member. | |
737 | - Fixed incorrectly applying htonl() on icp_common_t->shostid. | |
738 | - Call setsid() before exec() in ipc.c so that child processes | |
739 | don't receive SIGINT (etc) when running squid on a tty. | |
2f2dd5ad | 740 | - Changed StoreEntry->object_len to ->swap_file_sz so we |
741 | can verify the disk file size at restart. Moved object_len | |
742 | to MemObject->object_sz. Note object_sz is initialized | |
743 | to -1. If object_sz < 0, then we need to open the swap | |
744 | file and read the swap metadata. | |
745 | - Changed store_client->mem to ->entry because we need | |
746 | e->swap_file_sz to set mem->object_sz at swapin. | |
2f2dd5ad | 747 | - Renamed storeSwapData structure to storeSwapLogData. |
748 | - Fixed storeGetNextFile to not increment d->dirn. Added | |
749 | check for opendir() failure. | |
750 | - Fixed storeRebuildStart to properly link the directory | |
751 | list for storeRebuildfromDirectory mode. | |
e157f97f | 752 | - Added -S command line option to double-check store |
753 | consistency with disk files in storeCleanup(). | |
754 | - Fixed a problem with transactional logging. In many | |
755 | cases we were adding the public cache key and then | |
756 | logging a delete for the private key. This is worthless | |
757 | because during rebuild we could not locate the previous | |
758 | public-keyed entry. Now we assert that only public-keyed | |
759 | entries can be logged to swap.state. storeSetPublicKey() | |
760 | and storeSetPrivateKey() have been modified to log an | |
761 | ADD or DEL when the key changes. | |
762 | - Fixed storeDirClean bug. Needed to call | |
763 | storeDirProperFileno() so the "dirn bits" get set. | |
764 | - Fixed a storeRebuildFromDirectory bug. fullpath[] and | |
765 | fullfilename[] were static to that function and did | |
766 | not change when the "rebuild_dir" arg did. Moved these | |
767 | buffers to the rebuild_dir structure. | |
768 | - In storeRebuildFromSwapLog, we were calling storeRelease() | |
769 | for cache key collisions. This only set the RELEASE_REQUEST | |
770 | bit and did not clear the swap_file_number in the filemap or | |
771 | in the StoreEntry, so the swap file could get unlinked later | |
772 | when it was really released. | |
4e0f0471 | 773 | - Fixed FTP so that ';type=X' specifically sets the HTTP reply |
774 | content-type and content-encoding (Henrik Nordstrom). | |
775 | - Removed 'icon_content_type' configuration option. Content | |
776 | types now taken from mime.conf (Henrik Nordstrom). | |
2a9b2b73 | 777 | - Added additional memory malloc tracing and memory leak |
778 | detection. Use --enable-xmalloc-debug-trace configure | |
779 | option and -m command line option (Henrik Nordstrom). | |

93169941 | 781 | Changes to squid-1.2.beta14 (Feb 6, 1998): |
782 | ||
5471db88 | 783 | - Replaced snmplib free() calls with xfree(). |
784 | - Changed the 'net_db_name' hash table structure to | |
785 | make it easier to move names from one network to another | |
786 | (copied from 1.1 code). | |
93169941 | 787 | - Filled in some of the config dump routines (dump_acl, |
788 | dump_acl_access). | |
789 | - Full memory debugging option (--enable-xmalloc-debug-trace) | |
790 | (Henrik Nordstrom). | |
791 | - Filled-in and clarified many squid.conf comments (Oskar | |
792 | Pearson). | |
793 | - Fixed up handling of SWAP_LOG_DEL swap.state entries. | |
5471db88 | 794 | |
f91834bf | 795 | Changes to squid-1.2.beta13 (Feb 4, 1998): |
f577e074 | 796 | |
b4512acd | 797 | - NOTE: With this version the "swap.state" file format has |
798 | changed. Running this version for the first time will | |
799 | cause your current cache contents to be lost! | |
f91834bf | 800 | - NOTE: this version still has the bug where we don't rewind |
801 | a swapout file and rewrite the swap meta data. Objects | |
802 | larger than 8KB will be lost when rebuilding from the swap | |
803 | files. | |
d04dd4bf | 804 | - Combined various interprocess communication setup functions |
805 | into ipcCreate(). | |
806 | - Removed some leftover ICP_HIT_OBJ things. | |
807 | - Removed cacheinfo and proto_count() and friends; these are to | |
808 | be replaced in functionality by StatCounters and 5/60 minute | |
809 | average views via cachemgr. | |
810 | - Fixed --enable-acltree configure message (Masashi Fujita). | |
811 | - Fixed no reference to @LIB_MALLOC@ in src/Makefile.in | |
812 | (Masashi Fujita). | |
813 | - Fixed building outside of source tree (Masashi Fujita). | |
dbfed404 | 814 | - FTP: Format NLST listings, and inform the user that the NLST |
815 | (plain) format is available when we find a LIST listing that we | |
816 | don't understand (Henrik Nordstrom) | |
817 | - FTP: Use SIZE on Binary transfers, and not ASCII. The | |
818 | condition was inversed, making squid use SIZE on ASCII | |
819 | transfers (Henrik Nordstrom). | |
820 | - Enable virtual and Host: based acceleration in order to be | |
821 | able to use Squid as a transparent proxy without breaking | |
822 | either virtual servers or clients not sending Host: header | |
823 | the order of the virtual and Host: based acceleration needs | |
824 | to be swapped, giving Host: a higher precendence than virtual | |
825 | host (Henrik Nordstrom). | |
826 | - Use memmove/bcopy as detected by configure Some systems does | |
827 | not have memmove, but have the older bcopy implementation | |
828 | (Henrik Nordstrom). | |
6cf028ab | 829 | - Completely rewritten aiops.c that creates and manages a pool |
830 | of threads so thread creation overhead is eliminated (SLF). | |
831 | - Lots of mods to store.c to detect and cancel outstanding | |
832 | ASYNC ops. Code is not proven exhaustive and there are | |
833 | definately still cases to be found where outstanding disk ops | |
834 | aren't cancelled properly (SLF). | |
835 | - Changes to call interface to a few routines to support disk | |
836 | op `tagging', so operations can be cleanly cancelled on | |
837 | store_abort()s (SLF). | |
838 | - Implementation of swap.state files as transaction logs. | |
839 | Removed objects are now noted with a negative object size. | |
840 | This allows reliatively clean rebuilds from non-clean | |
841 | shutdowns (SLF). | |
842 | - Now that the swap.state files are transaction logs, there's | |
843 | now no need to validate by stat()ing. All the validation | |
844 | procedure does is now just set the valid bit AFTER all the | |
845 | swap.state files have been read, because by that time, only | |
846 | valid objects can be left. Object still need to be marked | |
847 | invalid when reading the swap.state file because there's no | |
848 | guarantee the file has been retaken or deleted (SLF). | |
849 | - An fstat() call is now added after every | |
850 | storeSwapInFileOpened() so object sizes can be checked. Added | |
851 | code to storeRelease() the object if the sizes don't match (SLF). | |
852 | - #defining USE_ASYNC_IO now uses the async unlink() rather than | |
853 | unlinkd() (SLF). | |
854 | - #defining MONOTONIC_STORE will support the creation of disk | |
855 | objects clustered into directories. This GREATLY improves disk | |
856 | performance (factor of 3) over old `write-over-old-object' | |
857 | method. If using the MONOTONIC_STORE, the | |
858 | {get/put}_unusedFileno stack stuff is disabled. This is | |
859 | actually a good thing and greatly reduces the risk of serving | |
860 | up bad objects (SLF). | |
861 | - Fixed unlink() in storeWriteCleanLogs to be real unlink() | |
862 | rather than ASYNC/unlinkd unlinks. swap.state.new files were | |
863 | being removed just after they were created due to delayed | |
864 | unlinks (SLF). | |
865 | - Disabled various assertions and made these into debug warning | |
866 | messages to make the code more stable until the bugs can be | |
867 | tracked down (SLF). | |
868 | - Added most of Michael O'Reilly's patches which included many | |
869 | bug fixes. Ask him for full details (SLF). | |
870 | - Moved aio_check_callbacks in comm_{poll|select}(). It was | |
871 | called after the fdset had been built which was wrong because | |
872 | the callbacks were changing the state of the read/write | |
873 | handlers prior to the poll/select() calls (SLF). | |
f09f5b26 | 874 | - Fixed ARP ACL memory leaks (Dale). |
f577e074 | 875 | - Eliminated URL and SHA cache keys. Cache keys will always |
876 | be MD5's now. | |
877 | - Fixed up store swap meta data. | |
878 | - Changed swap.state logs to a binary format. | |
f91834bf | 879 | - The swap.state logs are written transaction-style. |
d04dd4bf | 880 | |
b5cfbd5b | 881 | Changes to squid-1.2.beta12 (Jan 30, 1998): |
882 | ||
b4512acd | 883 | - Added metadata headers to cache swap files. This is an |
884 | incompatible change with previous versions. Running this | |
885 | version for the first time will cause your current cache | |
886 | contents to be lost. | |
9fc0b4b8 | 887 | - -D_REENTRANT when linking with -lpthreads (Henrik Nordstrom) |
888 | - Show symlink destinations as a hyperlink in FTP listings | |
889 | (Henrik Nordstrom) | |
3a4eaced | 890 | - Fixed not allocating enough space for rewriting URLs with |
891 | the Host: header (Eric Stern). | |
892 | - Year-2000 fixes (Arjan de Vet). | |
893 | - Fixed looping for cache hits on HEAD requests. | |
fc6dc767 | 894 | - Fixed parseHttpRequest() coredump for |
895 | "GET http://foo HTTP/1.0\r\n\r\n\r\n" | |
9fc0b4b8 | 896 | |
9f802cb1 | 897 | Changes to squid-1.2.beta11 (Jan 6, 1998): |
898 | ||
fd82d0b0 | 899 | - Fixed fake 'struct rusage' definition which prevented compling |
900 | on Solaris 2.4. | |
901 | - Fixed copy-by-ref bug for request->headers in | |
902 | clientRedirectDone() (Michael O'Reilly). | |
812db943 | 903 | - Workaround for Solaris pthreads closing FD 0 upon fork() |
904 | (Michael O'Reilly). | |
05fd71a7 | 905 | - Fixed shutdown bug with outgoing UDP sockets; we need to |
906 | disable their read handlers. | |
907 | - For comm_poll(), use the fast 50 msec timeout only when | |
908 | USE_ASYNC_IO is defined. | |
1fbc6de3 | 909 | - Fixed pointer bug when freeing AS# ACL entries. |
910 | - Fixed forgetting to reset Config.npeers to zero in free_peer(). | |
0f6bdbfa | 911 | - Fixed ICP bug causing excessive TIMEOUTs with sibling |
912 | neighbors. We must call the ICP reply callback even for | |
913 | sibling misses. | |
914 | - Fixed some dnsserver-related reconfigure bugs. Need to | |
915 | use cbdataLock, etc in fqdncache.c. Also don't want to | |
916 | use ipcacheQueueDrain() and fqdncacheQueueDrain(). | |
917 | - Fixed persistent connection bug. We were incorrectly | |
918 | deciding that non-200 replies without content-length | |
919 | would not have a reply body. | |
920 | - Fixed intAverage() precedence bug. | |
921 | - Fixed memmove() 'len' arg bug. | |
922 | - Changed algorithm for determining alive/dead state of peers. | |
923 | Instead of using a fixed number of unacknowledged ICP | |
924 | replies, it is now based on timeouts. If there are no ICP | |
925 | replies received from a peer within 'dead_peer_timeout' | |
926 | seconds, then we call it dead. | |
927 | - Added calls to getCurrentTime() in | |
928 | comm_{select,poll}_incoming() when ALARM_UPDATES_TIME is not | |
929 | being used. | |
930 | - Fixed shutdown bug when the incoming and outgoing ICP socket | |
931 | is the same file descriptor. | |
e970f357 | 932 | - Added buffered writes for storeWriteCleanLogs() (Stewart |
933 | Forster). | |
934 | - Patches for Qnx4 (Jean-Claude MICHOT). | |
935 | - Fixed returning void functions which seems to be a GCC-ism. | |
e5f4e1b0 | 936 | - New configure script options (Henrik Nordstrom): |
937 | --enable-new-storekey=[sha|md5(|url)] (was --enable-hashkey) | |
938 | --enable-acltree | |
939 | --enable-icmp | |
940 | --enable-delay-hack | |
941 | --enable-useragent-log | |
942 | --enable-kill-parent (this should be named -hack) | |
943 | --enable-snmp | |
944 | --enable-time-hack | |
945 | --enable-cachemgr-hostname[=hostname] (new) | |
946 | --enable-arp-acl (new) | |
947 | - Added Doug Lea malloc-2.6.4 to the distribution, so that | |
948 | people easily can try a decent malloc package if they syspect | |
949 | their malloc is broken. --enable-dlmalloc (Henrik Nordstrom). | |
950 | - Made XMALLOC_DEBUG_COUNT working again. Requires a small stub | |
951 | function (Henrik Nordstrom). | |
952 | - Removed top-level Makefile. People must now run 'configure' | |
953 | before 'make'. | |
714ace98 | 954 | - Fixed checkFailureRatio() implementation. |
82b3c7d9 | 955 | - Made 'squid -z' behave like the 1.1 version. |
e5f4e1b0 | 956 | |
fd82d0b0 | 957 | |
ab9a3f7e | 958 | Changes to squid-1.2.beta10 (Jan 1, 1998): |
959 | ||
960 | - Fixed content-length bugs for 204 replies, 304 replies, | |
961 | and HEAD requests (Henrik Nordstrom). | |
962 | - Fixed errorAppendEntry() bug in gopherReadReply(). | |
963 | - Basic support for FTP URL typecodes (;type=X). | |
9c965c1b | 964 | - Support for access controls based on ethernet MAC addresses |
ab9a3f7e | 965 | (Dale). |
966 | - Initial URN support; see | |
967 | http://squid.nlanr.net/Squid/urn-support.html | |
968 | - Fixed client-side persistent connections for objects with | |
969 | bad content lengths (Henrik Nordstrom). | |
970 | - Fixed bad call to storeDirUpdateSwapSize() for objects which | |
971 | never reach SWAPOUT_DONE state. | |
68e3a9df | 972 | - Fixed up poll() #defines in squid.h (Stewart Forster). |
973 | - Changed poll() timeout from 1000 msec to 50 msec for | |
974 | better performance under low load (Stewart Forster). | |
e7a1fde6 | 975 | - Changed storeWriteCleanLogs() to write objects in the LRU |
976 | list order instead of the random hash table order. | |
109ff6af | 977 | - Fixed FTP bug when data socket connections fail or timeout. |
978 | - Reuse FTP data connection when possible (Henrik Nordstrom). | |
979 | - Added configure options (Henrik Nordstrom) | |
980 | --enable-store-key=sha|md5 | |
981 | --enable-xmalloc-statistics | |
982 | --enable-xmalloc-debug | |
78743365 | 983 | --enable-xmalloc-debug-count |
984 | --async-io | |
109203bf | 985 | - Fixed confusing with the use/meaning of ERR_CANNOT_FORWARD |
986 | by creating ERR_FORWARDING_DENIED and changing the | |
987 | content of the ERR_CANNOT_FORWARD text. | |
4e9c07c1 | 988 | - Fixed pipeline request bug from using strdup() (Henrik |
989 | Nordstrom). | |
990 | - Call clientReadRequest() directly instead of commSetSelect() | |
991 | for pipelined requests (Henrik Nordstrom). | |
1b02b5be | 992 | - Fixed 4k page leak in icpHandleIMSReply(); |
993 | - Renamed 'icp*' functions to 'client*' names in client_side.c. | |
e7a1fde6 | 994 | |
b90a0f8d | 995 | Changes to squid-1.2.beta8 (Dec 2, 1997): |
996 | ||
eae03fc8 | 997 | - Fixed accessLogLog() to log ident from Proxy-Authorization |
998 | request header (BoB Miorelli). | |
226f9ba2 | 999 | - Fixed #includes, prototypes, etc. in SNMP source files. |
1000 | - Moved 'POLLRDNORM' and 'POLLWRNORM' macro checks from | |
1001 | include/config.h.in to src/squid.h | |
1002 | - Moved 'num32' typedefs from src/typedefs.h to | |
1003 | include/config.h.in. | |
1004 | - Moved snmplib/md5.c to lib/md5.c. | |
1005 | - Added MD5 cache key support. | |
1006 | - Removed xmalloc() return check in uudeocde.c | |
1007 | - Added 'ifdef' support to cf_gen.c for optional code (e.g. SNMP) | |
1008 | - Changed 'client' program to provide easier cache manager access, | |
1009 | e.g.: 'client mgr:info' | |
1010 | - Fixed 'client' to send 'Connection' instead of 'Proxy-Connection' | |
1011 | for simulated keep-alive requests. | |
1012 | - Removed 'fd' arg from clientProcess* functions. | |
9e3468d5 | 1013 | - Fixed bugs from using errorSend() on persistent/pipelined |
226f9ba2 | 1014 | client connections. A latter request should not be allowed to |
1015 | write to the client fd until the current request completes. | |
1016 | Now use errorAppendEntry() for such situations. | |
1017 | - Fixed content-length bugs. We were using content-length == 0 | |
1018 | to also indicate a lack of content-length reply header. But | |
1019 | 'content-length: 0' might appear in a reply, so now use -1 to | |
1020 | indicate that no content length given. | |
1021 | - Split up clientProcessRequest() into smaller chunks so it | |
1022 | might be easier to follow. | |
1023 | - renamed various client_side.c functions to start with 'client' | |
1024 | instead of 'icp'. | |
1025 | - Fixed a 'cbdata leak' from the comm.c close handlers. | |
1026 | - Fixed a 'cbdata leak' from the comm.c connect routines. | |
1027 | - Fixed comm_select() and comm_poll() to stop looping on the | |
1028 | incoming HTTP/ICP sockets. If there are fewer than 7 FD's | |
1029 | ready for I/O, the incoming sockets might not get service, so | |
1030 | comm_select() would be called for up to 7 times until the | |
1031 | 'incoming_counter' was incremented enough to trigger a call | |
1032 | to comm_select_incoming(). Now we make sure | |
1033 | comm_select_incoming() gets called if select returns less | |
1034 | than 7 ready FD's. | |
9e3468d5 | 1035 | - Added errorpage '%B' token to generate FTP URLs with a '%2f' |
1036 | inserted at the start of the url-path. calls ftpUrlWith2f(). | |
1037 | (Henrik Nordstrom). | |
226f9ba2 | 1038 | - Changed fqdncache.c to use LRU double-linked list instead of qsort() |
1039 | for replacement and cachemgr output. | |
1040 | - Changed ipcache.c to use LRU double-linked list instead of qsort() | |
1041 | - Changed hash_insert() and hash_join() to return void. | |
1042 | for replacement and cachemgr output. | |
1043 | - Moved StoreEntry->method member to MemObject->method. | |
1044 | - Made StoreEntry->flags 16 bits. | |
1045 | - Made StoreEntry->refcount 16 bits. | |
1046 | - Changed URL-based public cache key to always include the request | |
1047 | method. | |
eae03fc8 | 1048 | |
95bc9f0b | 1049 | Changes to squid-1.2.beta7 (Nov 24, 1997): |
1050 | ||
6a11653c | 1051 | - Fixed poll() for Linux (David Luyer). |
1052 | - SHA optimizations (David Luyer). | |
1053 | - Fixed errno clashes with macro on Linux (David Luyer). | |
1054 | - Fixed storeDirCloseSwapLogs(); logs might not be open. | |
1055 | - Fixed storeClientCopy2() bug. Detect when there is | |
1056 | no more data to send for objects in STORE_OK state. | |
19ee64b1 | 1057 | - Fixed FTP truncation bug when ftpState->size == 0, e.g. |
1058 | especially directory listings. | |
95bc9f0b | 1059 | - Mega FTP fix from Henrik Nordstrom. A better job of |
1060 | implementing the '%2f' hack. | |
1061 | - Fixed some pipelined request bugs. storeClientCopy() was | |
1062 | being given the wrong StoreEntry, and we had a race condition | |
1063 | which is now handled by storeClientCopyPending(). | |
99077fe6 | 1064 | - Added initial SNMP support. |
6a11653c | 1065 | |
2c9b45c9 | 1066 | Changes to squid-1.2.beta6 (Nov 13, 1997): |
1067 | ||
1b5516d3 | 1068 | - Fixed Authorized responses getting swapped out when they |
1069 | don't have Proxy-Revalidate reply header. | |
1070 | - Fixed Proxy Authentication support. We never sent back | |
1071 | a 407 reply, and were incorrectly incrementing the passwd | |
1072 | before comparing it. | |
1073 | - Fixed stat()ing pathnames for default values before parsing | |
1074 | config file (Ron Gomes). | |
1075 | - Fixed logging request and response headers on separate lines | |
1076 | (Ron Gomes). | |
1077 | - Fixed FTP Authentication message (Henrik Nordstrom). | |
1078 | - Changed Proxy Authentication to trigger a reread of the passwd | |
1079 | file if a password check fails (Henrik Nordstrom). | |
1080 | - Changed FTP to retry the first CWD with a leading slash if it | |
1081 | fails without one. | |
1082 | ||
8c17a569 | 1083 | Changes to squid-1.2.beta5 (Nov 6, 1997): |
1084 | ||
90045285 | 1085 | - Track the 'keep-alive ratio' for a peer as the ratio of |
1086 | the number of replies including 'Proxy-Connection: Keep-Alive' | |
1087 | compared to the number of requests sent. If the peer does | |
1088 | not support Persistent connections then this ratio will tend | |
1089 | toward zero. If the ratio is less than 50% after 10 requests | |
1090 | then we'll stop sending Keep-Alive. | |
8c3994aa | 1091 | - Proper support for %nn escapes in FTP, and numerous |
1092 | other fixes (Henrik Nordstrom). | |
1093 | - Support for Secure Hash Algorithm and framework for other | |
1094 | hash functions as cache keys. | |
1095 | - Fixed SSL snprintf() bug which broke SSL proxying. | |
1096 | - Fixed store_dir swap log bug from reconfigure (SIGHUP). | |
8c17a569 | 1097 | - Fixed LRU Reference Age bug. The arg to pow() must be |
8031bd43 | 1098 | minutes, not seconds. |
90045285 | 1099 | |
9ddfb255 | 1100 | Changes to squid-1.2.beta4 (Oct 30, 1997): |
1101 | ||
a493f974 | 1102 | - Fixed DST bug in rfc1123.c |
1103 | - Changed default http_accel_port to 80. | |
1104 | - added errorCon() as a ErrorState constructor function | |
1105 | (Max Okumoto). | |
1106 | - Added ERR_FTP_FAILURE message for ftpFail(). | |
1107 | - For FTP, the timeout callback must be moved to the 'data' | |
1108 | descriptor when data transfer begins. Otherwise we are | |
1109 | likely to get a timeout on the control descriptor. | |
1110 | - Fixed double-free bug in httpRequestFree(). | |
1111 | - Fixed store_swap_size counting bug in storeSwapOutHandle(). | |
1112 | ||
409a6aad | 1113 | Changes to squid-1.2.beta3 (Oct 29, 1997): |
1114 | ||
1115 | - Initialize _res.options to RES_DEFAULT in dnsserver.c. | |
1116 | - Fix assertions which assumed 4-byte pointers. | |
1117 | - Fix missing % in fqdncache.c snprintf(). | |
1118 | ||
5a2d610b | 1119 | Changes to squid-1.2.beta2 (Oct 28, 1997): |
1120 | ||
8c3994aa | 1121 | - Fixed aiops.c and async_io.c so that they actually compile |
f5b8bbc4 | 1122 | with USE_ASYNC_IO (Arjan de Vet). |
1123 | - Fixed errState->errno causing problems with some macros | |
1124 | (Michael O'Reilly). | |
d287f51e | 1125 | - Fixed memory leaks in pconn.c (Max Okumoto). |
0866009b | 1126 | - Enhanced 'client' program with 'ping' behaviour (Ron Gomes). |
272547b5 | 1127 | - Fixed InvokeHandlers() from calling memCopy() for ALL |
1128 | store_client's with callbacks. A store_client might be reading | |
1129 | from disk. | |
5a2d610b | 1130 | - Rewrote storeMaintainSwapSpace(). No longer will we scan one |
272547b5 | 1131 | bucket at a time. Instead we'll maintain a single LRU |
1132 | list. When an object is 'touched' we move it to the | |
1133 | top of this list. When we need disk space, we delete | |
1134 | from the bottom. | |
5a2d610b | 1135 | - Removed storeGetSwapSpace(). |

871f0b8a | 1137 | Changes to squid-1.2.beta1 (): |
1138 | ||
1139 | - Reworked storage manager to not keep objects in memory during | |
1140 | transit. In other words, no separate NOVM distribution. | |
1141 | - Lots of cleanup and debugging for beta release. | |
1142 | - Use snprintf() everywhere instead of sprintf(). | |
1143 | - The 'in_memory' hash table has been replaced with a | |
1144 | doubly-linked list. New objects are added to the head of | |
1145 | the list. When memory space is needed, old objects are | |
1146 | purged from the tail of the list. | |

6684fec0 | 1155 | - Simpler cacheobj implementation. |
6605655c | 1156 | - persistent connection histogram |
8872e1f8 | 1157 | - SERVER-SIDE PERSISTENT CONNECTIONS: |
1158 | - Added pconn.c | |
1159 | - Addec Cofig.Timeout.pconn; default 120 seconds | |
1160 | - Added httpState->flags | |
1161 | - Added flags arg to httpBuildRequestHeader() | |
1162 | - Added HTTP_PROXYING and HTTP_KEEPALIVE flags | |
1163 | - Added 'Connection' to allowed HTTP headers (http-anon.c) | |
1164 | - Added 'Proxy-Connection' to allowed HTTP headers | |
1165 | (http-anon.c) | |
a7736231 | 1166 | - Merged proxyhttpStart() with httpStart() and created |
8872e1f8 | 1167 | new httpBuildState(). |
1168 | - New httpPconnTransferDone() detects end-of-data on | |
1169 | persistent connections. | |

88738790 | 1171 | Changes to squid-1.2.alpha5 (): |
1172 | ||
1173 | - New configuration system. Everything is generated from | |
1174 | 'cf.data.pre', including the main parser, setting defaults, | |
1175 | outputting current values, and freeing memory. | |
1176 | This also involved moving some of the local data structures | |
1177 | (e.g. struct _acl *AclList in acl.c) to the Config | |
1178 | structure. (Max Okumoto) | |
1179 | - No more '/i' for regular expressions. Now insert a '-i' | |
1180 | to switch to case-insensitive. Use '+i' for case-sensitive. | |
1181 | - When you have a variable named the same as its type, sizeof() | |
1182 | gets the wrong one (fde). | |
1183 | - Need to flush unbuffered logs before fork(). | |
1184 | - Added two fields swap log: refcount and e->flag. | |
1185 | - Removed all the .h files for each .c file. Now #include stuff | |
1186 | is in either: defines.h, enums.h, typedefs.h, structs.h, | |
1187 | or protos.h, globals.h. This greatly reduces dependencies | |
1188 | between the various source files. | |
1189 | - globals.c is generated from globals.h by a Perl script. | |
8ee3ca2c | 1190 | - Started customizable error texts. |

ec973719 | 1194 | - New MIME configuration, regular expression based |
1195 | - Added request_timeout config option | |
1196 | - Multiple HTTP sockets (Lincoln Dale). | |
1197 | - Moved 'fds_are_n_free' check to httpAccept(). | |
1198 | - s/USE_POLL/HAVE_POLL/; make poll() default if available. | |
7e49f700 | 1199 | - Changed storeRegister to use offsets and make immediate |
1200 | callbacks if appropriate. | |
1201 | - Removed icpDetectClientClose(). Some of that functionality | |
1202 | goes into clientReadRequest() and the rest into | |
1203 | httpRequestFree(). | |
b1b387d1 | 1204 | - Moved IP lookups to commConnect stuff. |
1205 | - Added support for retrying connect(). | |
858164fc | 1206 | - New inline debug() macro (David Luyer). |
e174e0fe | 1207 | - Replace frequent gettimeofday() calls with alarm(3) based |
1208 | clock. Need to add more gettimeofday() calls to get back | |
a59968c7 | 1209 | high-resolution timestamp logging (Andres Kroonmaa). |
0153d498 | 1210 | - Added support for Cache-control: proxy-revalidate; |
1211 | based on squid-1.1 patch from Mike Mitchell. | |
ec973719 | 1212 | |
3b08d32d | 1213 | Changes to squid-1.2.alpha3 (): |
1214 | ||
1215 | - Implemented persistent connections between clients and squid. | |
1216 | - Moved various FD tables (comm.c, fdstat.c, disk.c) to a single | |
1217 | table in fd.c. | |
1218 | - Removed use of FD as an identifier in certain callback | |
1219 | operations (ipcache, fqdncache). | |
1220 | - General code cleanup. | |
1221 | - Fixed typedefs for callback functions. | |
1222 | - Removed FD lifetime/timeout dichotomy. Now we only have | |
1223 | timeouts, however the lifetime concept/keyword may still | |
1224 | linger in certain places. | |
1225 | - Change Makefile 'realclean' target to 'distclean' | |
1226 | - Changed config file parsing of time specifications to use | |
1227 | parseTimeLine(). | |
1228 | - Removed storetoString.c | |

1235 | ||
1236 | - Unified peer selection algorithm. | |
75e88d56 | 1237 | - aiops.c and aiops.h are a threaded implementation of |
1238 | asynchronous file operations (Stewart Forster). | |
1239 | - async_io.c and async_io.h are complete rewrites of the old | |
1240 | versions (Stewart Forster). | |
6ad85e8a | 1241 | - Rewrote all disk file operations of squid to support |
75e88d56 | 1242 | the idea of callbacks except where not required (Stewart |
1243 | Forster). | |
75e88d56 | 1244 | - Background validation of 'tainted' swap log entries (Stewart |
1245 | Forster). | |
1246 | - Modified storeWriteCleanLog to create the log file using the | |
1247 | open/write rather than fopen/printf (Stewart Forster). | |
1248 | - Added the EINTR error response to handle badly interrupted | |
1249 | system calls (Stewart Forster). | |
6ad85e8a | 1250 | - UDP_HIT_OBJ not supported, removed. |
1251 | - Different sized 'cache_dirs' supported. | |
