8f897f34 | 1 | Changes to Squid-2.1 (): |
2 | ||
3 | - Changed delayPoolsUpdate() to be called as an event. | |
4 | - Replaced comm_select FD scanning loops with global fd_set | |
5 | structures. Inspired by Jeff Mogul's patch for squid 1.1. | |
9e1559ea | 6 | - Moved functions common to dns.c, redirect.c, authenticate.c, |
7 | ipcache.c, and fqdncache.c into helper.c. | |
0753aa46 | 8 | - Changed storeClientCopy2() so that it keeps sending the remainder |
9 | of a STORE_ABORTED request, instead of cutting off the client as | |
10 | soon as the object becomes aborted. | |
f0538986 | 11 | - Fixed combined ipf-transparent proxy and a local http-accelerator |
12 | operation (Quinton Dolan). | |
13 | - Rewrote base64_decode.c because of potential buffer overrun | |
14 | bugs. | |
912432d8 | 15 | - Configurable handling of whitespace in request URI's. |
16 | See 'uri_whitespace' in squid.conf. | |
e33ec474 | 17 | - Added ability to generate HTTP redirect messages from |
18 | the redirector output by prepending "301:" or "302:" to the | |
19 | new url. See FAQ 4.16 for more details. | |
829a9357 | 20 | - Eliminated refreshWhen() which was out-of-sync with refreshCheck() |
21 | potentially causing under-utilized cache digests | |
22 | - Maintain refreshCheck statistics on per-protocol basis so we | |
23 | can tell why ICP or Digests return too many misses, etc. | |
c68e9c6b | 24 | - Fixed delay_pools.c class2/class3 typo (Simon Woods). |
25 | - Changed squid.conf's default access controls to deny all | |
26 | HTTP requests. Admins must write ACL rules to specifically | |
27 | allow their local clients. | |
28 | - Patched French error messages (Mathias HERBERTS). | |
29 | - NextStep porting fixes by Mike Laster: | |
30 | - use xstrdup() in cf_gen.c | |
31 | - check for putenv() in configure | |
32 | - #define S_ISDIR macro | |
33 | - Added --disable-poll configure option (Henrik Nordstrom). | |
34 | - Fixed internal URL hostname case bugs (Henrik Nordstrom). | |
35 | - Patched ftp.c so we never cache autenticated FTP requests | |
36 | (Henrik Nordstrom). | |
37 | - Fixed FTP authentication. We tried to unescape authentication | |
38 | given by basic authentication which is not URL escaped | |
39 | (Henrik Nordstrom). | |
40 | - Fixed HTTP version for common logfile format (Henrik Nordstrom). | |
41 | - Added 'redirect_rewrites_host_header' option to disable rewriting | |
42 | of Host header for redirector responses (Henrik Nordstrom). | |
43 | - Allow semi-customized error message signatures (Henrik Nordstrom). | |
44 | - Fixed bug with errors for unsupported requests (Henrik Nordstrom). | |
45 | - Fixed handling of blank lines in ACL input files (Henrik | |
46 | Nordstrom). | |
47 | - Changed proxy_auth ACL type to consist of a list of valid | |
48 | users. REQUIRED == any (same as ident ACL). ACL type user | |
49 | changed to ident since this is what it really is. | |
50 | (Henrik Nordstrom). | |
51 | - Fixed long URL bugs; make sure 'log_uri' never exceeds | |
52 | MAX_URL bytes. | |
53 | - Allow comments in external ACL files (Gerhard Wiesinger). | |
54 | - Added 'range_offset_limit' configuration option. Requests | |
55 | with ranges that start after this value will be passed | |
56 | on unmodified, and Squid will not cache the response | |
57 | (Henrik Nordstrom). | |
58 | - Added Client HTTP Hit byte counters to 'counters' output | |
59 | (Douglas Swarin). | |
60 | - Got Squid to compile with --enable-async-io on FreeBSD. | |
61 | - Fixed infinite loop bug for cachemgr 'config' option. | |
62 | - Fixed cachability bugs for replies with Pragma: no-cache. | |
63 | - Made content-type multipart/x-mixed-replace uncachable. | |
64 | - Y2K fix for parsing dates in "Wed Jun 9 01:29:59 1993 GMT" | |
65 | format (Richard Kettlewell). | |
66 | - Fixed passing -s option to dnsserver processes (Alvaro Jose | |
67 | Fernandez Lago). | |
68 | - Changed proxy_auth to work on internal objects and when in | |
69 | accelerator mode. (Henrik Nordstrom) | |
70 | - Added login=user:password option to cache_peer directive to | |
71 | be used from a dial-up cache where the parent requires proxy | |
72 | authentication. (Henrik Nordstrom) | |
73 | - If you want to "auto-login", then use a URL on the form | |
74 | http://username:password@server/.... Squid now picks this up | |
75 | when going direct, and turns it into basic WWW | |
76 | authentication. It is also possible to do automatic login to | |
77 | certain servers by using a redirector to add the needed | |
78 | authentication information. (Henrik Nordstrom) | |
8f897f34 | 79 | |
41587298 | 80 | Changes to Squid-2.0 (October 2, 1998): |
71d6dc56 | 81 | |
4c154d99 | 82 | - Added NAT/Transparent hijacking code from Quinton Dolan. |
83 | - Added actual filesystem usage to cachemgr 'storedir' page. | |
41587298 | 84 | Only works for operating systems which support statvfs(). |
a79d724b | 85 | - Fixed HTCP compile-time bugs. |
86 | - Fixed quick_abort bugs. Configured values are stored as | |
87 | Kbytes, not bytes. | |
41587298 | 88 | - Removed fwdAbortFetch(). It breaks quick_abort and seems |
89 | mostly useless. | |
0da7d807 | 90 | - Changed storeDirSelectSwapDir() to skip swap directories |
91 | when their utilization is over the high water mark ratio. | |
9ca005ac | 92 | - Fixed off-by-one bug for dead neighbor detection (Joe Ramey). |
18cc143b | 93 | - fixed bugs in Content-Range header generation |
94 | - changed the way Range requests are handled: | |
71d6dc56 | 95 | - do not "advertise" our ability to process ranges at |
96 | all | |
97 | - on hits, handle simple ranges and forward complex | |
98 | ones | |
99 | - on misses, fetch the whole document for simple ranges | |
100 | and forward range request for complex ranges | |
101 | The change is supposed to decrease the number of cases when | |
102 | clients such as Adobe acrobat reader get confused when we | |
103 | send a "200" response instead of "206" (because we cannot | |
104 | handle complex ranges, even for hits) Note: Support for | |
105 | complex ranges requires storage of partial objects. | |
41587298 | 106 | - Removed SNMP mib-2.system group from squid. |
107 | - Removed SNMP ability to iterate through ipcache and friends. | |
108 | - Added SNMP ipcache/fqdncache basic statistics. | |
109 | - Converted SQUID-MIB to SMIv2 (RFC 1902). | |
110 | - Moved SQUID-MIB to enterprises section of the tree in preparation | |
abcf1bb2 | 111 | of the split into PROXY-MIB & SQUID-MIB. |
41587298 | 112 | - Corrected minor errors in SQUID-MIB. |
113 | - Moved uptime into cacheSystem from cacheConfig. | |
114 | - Corrected a number of get-next-request bugs, snmpwalk should now | |
abcf1bb2 | 115 | return all objects and not skip some. |
41587298 | 116 | - Fixed netdbClosestParent() so it won't return sibling |
117 | peers. | |
118 | - Fixed a bug with secondary clients on entries with | |
119 | ENTRY_BAD_LENGTH set. We should release the | |
120 | bad entry to prevent secondary clients jumping on. | |
121 | - Changed MIB to prevent parse warnings at startup. | |
f0538986 | 122 | * Changes below have been made to SQUID_2_0_PATCH1 |
9689d97c | 123 | - Fixed a forwarding loop bug. Even though we were detecting |
124 | a loop, it was not being broken. | |
125 | - Try to prevent sibling forwarding loops by NOT forwarding a | |
126 | request to a sibling if we have a stale copy of the object. | |
127 | Validation requests should only be sent to parents (or | |
128 | direct). | |
129 | - Fixed ncsa_auth hash bugs when re-reading password file. | |
130 | - Changed clientHierarchical() so that by default SSL/CONNECT | |
131 | requests do NOT go to neighbor caches. | |
d87ebd78 | 132 | - Changed clientHandleIMSReply() to not call storeAbort() |
133 | because there can be more than one client hanging on the | |
134 | StoreEntry. This hopefully fixes "store_status != | |
135 | STORE_ABORTED" assertions. | |
f0538986 | 136 | - Added temporary fix to httpMakePublic() to prevent assertions |
137 | (!EBIT_TEST(e->flags, RELEASE_REQUEST)) in storeSetPublicKey(). | |
138 | * Changes below have been made to SQUID_2_0_PATCH2 | |
139 | - PATCH1 introduced a seriously stupid bug which prevented ICP | |
140 | queries for all requests. Fixed by checking | |
141 | request->hierarchical in peerSelectFoo(). | |
18cc143b | 142 | |
4c154d99 | 143 | Changes to squid-1.2.beta25 (September 21, 1998): |
144 | ||
4b66bfd3 | 145 | - Fixed async IO bugs from adding filedescriptor arg to AIOCB |
146 | callbacks (Henrik Nordstrom). | |
147 | - Fixed store_swapout.c assertion. We were freeing object data | |
148 | past the swapout_done offset. This probably happens (only?) | |
149 | when an object changes from cachable to uncachable while | |
150 | it is being swapped out. | |
a260d877 | 151 | - Added MEM_CLIENT_SOCK_BUF type so we can change the size |
152 | of the buffers used for writing data to the client sockets. | |
669d90e7 | 153 | - Added configure check for libbind.a. If found, it will be |
154 | used instead of libresolv.a. | |
155 | - Changed fwdStart() to always allow internally generated | |
dddd5b55 | 156 | requests, such as for peer digests. These requests are |
157 | known to fwdStart() because the address arg is set to | |
158 | 'no_addr'. | |
669d90e7 | 159 | - Completed initial HTCP implementation. It works, but is not |
160 | tested much. | |
2d5c8e74 | 161 | - Added counters for I/O syscalls. |
162 | - Fixed httpMaybeRemovePublic. With broken ICP neighbors | |
163 | (netapp) Squid doesn't use private keys. This caused us | |
164 | to remove almost every object from the cache. | |
165 | - Added 'asndb' cachemgr stats to show AS Number tree. | |
dddd5b55 | 166 | - Fixed AS Number byte-order bug for netmasks. |
2d5c8e74 | 167 | - Fixed comm_incoming calling rate for high loads (Stewart |
168 | Forster). | |
426012d2 | 169 | - Give always_direct higher precedence than never_direct |
170 | (Henrik Nordstrom). | |
dddd5b55 | 171 | - Changed PORT ACL type to accept ranges. Now you can easily |
172 | deny, for example, all priveleged ports except 80, 70, 21, | |
173 | etc. | |
174 | - ARP ACL fixes for Linux (David Luyer). | |
175 | - Replaced various "EBIT" flags bitfileds with structures of | |
176 | "int:1" members. | |
177 | - Changed storeKeyPrivate and storeKeyPublic to be a bit more | |
178 | efficient by removing snprintf(). This causes an | |
179 | incompatibility with old cache keys, however. To transition, | |
180 | we will look up both the new and old style keys for about the | |
181 | next 30 days. After that, if you haven't run this (or a | |
182 | future) version, your cache contents will be lost. | |
183 | - Made the client-side write buffer size configurable with | |
184 | a #define in defines.h. By default it is still 4096 bytes. | |
185 | - Removed redirectUnregister(). It should be unnecessary | |
186 | because of cbdata locks. | |
187 | - Fixed multiple HEAD request brokennesses (Henrik Nordstrom). | |
188 | - Changed non-blocking connect(2) code to call getsockopt() | |
189 | instead of connect() again. This is the approach recommended | |
190 | by Stevens, and fixes bugs on BSD-ish systems when subsequent | |
191 | connect() calls loop with EAGAIN status. | |
192 | - Added MD5 cache keys to memory pool accounting. | |
193 | - Added code to track number of open DISK descriptors and stop | |
194 | swapping out objects if the number of disk descriptors becomes | |
195 | too large. For now the limit must be manually configured with | |
196 | the 'max_open_disk_fds'. By default, there is no limit. | |
197 | - Stopped encoding a request method in the high byte of the ICP | |
198 | reqnum field. Instead queried cache keys are copied to a | |
199 | static array, indexed by the reqnum, modulo the array size. | |
200 | Now we just use the request number to lookup a cache key, | |
201 | instead of rebuilding it from the ICP reply URL and method, | |
202 | unless we have netapp neighbors--they don't do reqnum | |
203 | properly. | |
204 | - Fixed reconfigure memory access bugs in redirect.c. | |
0753aa46 | 205 | - Ignore unreasonably large ICP RTT values which cause overflow |
206 | bugs in calculating the average RTT (thanks Niall!) | |
4b66bfd3 | 207 | |
8e6a43e8 | 208 | Changes to squid-1.2.beta24 (August 21, 1998): |
209 | ||
6c4067e5 | 210 | - Added Bulgarian error pages by Evgeny Gechev. |
ceb79b2b | 211 | - Changed StoreEntry->lock_count to a u_short. |
c7d6216e | 212 | - Replaced urlcmp with strcmp |
213 | - Fixed pragma no-cache ejecting ENTRY_SPECIAL objects | |
214 | (Henrik Nordstrom). | |
215 | - Eliminated unneeded BASE HREF on "root" directories (Henrik | |
216 | Nordstrom). | |
217 | - Fixed peerDigestFetchFinish() assertion caused by forwarding | |
218 | failures (e.g. miss_access rules). | |
ada249f8 | 219 | - Changed signal handlers with ASYNC_IO and Linux so that |
220 | -k command line options work (Miquel van Smoorenburg). | |
4616f9ea | 221 | - Rewrote shutdown code to use events instead of setting |
222 | FD timeouts. | |
903e21a0 | 223 | - Fixed cachemgr 'objects' (statObjects()) by adding a check |
b6a76fb2 | 224 | for READ_AHEAD_GAP, and calling storeCheckSwapout() in |
225 | storeBufferFlush(). Otherwise, the read-past pages would | |
226 | never be freed. | |
681979a2 | 227 | - Fixed DNSSERVER shutdown bugs. The re-opened dnsserver processes |
228 | were being closed by the dnsServerShutdown event. | |
b6a76fb2 | 229 | - Modified storeHashInsert() to insert PRIVATE objects at |
230 | the tail of the LRU list, and PUBLIC objects at the head. | |
231 | Thus, PRIVATE objects get kicked out quicker. | |
95e36d02 | 232 | - Added David Luyer's DELAY_POOLS code. |
54b5b3e5 | 233 | - Fixed a bug due to HEAD replies which lack the end-of-headers |
234 | line. | |
235 | - Made proxy-auth realm string configurable (Bob Franklin) | |
236 | - Changed default mime time to a viewable one (Henrik Nordstrom). | |
237 | - configure fixes for Sony's NEWS-OS 6.x (Makoto MATSUSHITA). | |
238 | - Fixed 'you are running out of filedescriptors' bug which | |
239 | could cause the HTTP incoming connection handler to not | |
240 | be reset. | |
e23fbf04 | 241 | - Changed syslog logging. Now squid debug levels 0 and 1 go |
d737baa0 | 242 | to syslog. Level 0 gets LOG_WARNING and level 1 gets LOG_NOTICE |
e23fbf04 | 243 | (this needs more work!) |
2cb51fe0 | 244 | - Fixed memory access errors in statAvgTick(). |
abc1237e | 245 | - Fixed duplicate requestUnlink() bug in forward.c |
6c4067e5 | 246 | - Fixed possible memory access bugs from not setting e->mem_obj |
247 | = NULL in destroy_MemObject(). | |
248 | - Deleted TCP_IMS_MISS tag. Always use TCP_IMS_HIT instead. | |
249 | - Modified headersEnd and httpMsgIsolateHeaders to account | |
250 | for funky line terminations such as CRCRNL. | |
251 | (``but Netscape and IE _tolerate_ this'') | |
252 | - Fixed carp functions (Eric Stern). | |
253 | - Replaced internal proxy_auth code with extern authentication | |
254 | module (Arjan de Vet). | |
255 | - moved hash.c to libmiscutil.a. | |
e931f99a | 256 | - Fixed handling of ICP queries with whitespace in URLs. |
257 | Now we return ICP error and escape the URL before logging. | |
3a15a393 | 258 | - Added configure check for socklen_t (David Luyer). |
259 | - Removed USE_SPLAY #defines; it is now standard. | |
3a76c002 | 260 | - Added FD arg to async IO callbacks (AIOCB) so we can eliminate |
261 | temporary disk_ctrl_t structures. | |
262 | - Changed ENOSPC disk write errors to reduce specific cache_dir | |
263 | sizes, and not just the size of the cache as a whole. | |
f9cece6e | 264 | - Added httpMaybeRemovePublic() to purge public objects for |
265 | certain responses even though they are uncachable. This is | |
266 | needed, for example, when an initially cachable object | |
267 | later becomes uncachable. | |
8e6a43e8 | 268 | - Added refresh_pattern options to ignore client reloads |
269 | (Henrik Nordstrom) | |
270 | - Relocated disk.c code which combines blocks for writing | |
271 | (Stewart Forster). | |
c7d6216e | 272 | |
857703c6 | 273 | Changes to squid-1.2.beta23 (June 22, 1998): |
274 | ||
cf7f704c | 275 | - Added Turkish error pages by Tural KAPTAN. |
66bbb757 | 276 | - Added basic support for Range requests. For most cachable |
277 | requests, Squid replies with an "Accept-Ranges" header. Upon | |
278 | receiving a potentially cachable Range request for a not | |
279 | cached object, Squid requests the whole object from origin | |
280 | server and then replies with specified range(s) to the | |
281 | client. Multi-range requests are supported. Adjacent | |
282 | overlapping ranges are merged. If-Range requests are | |
283 | supported. Limitations: Multi-range requests with out of | |
284 | order ranges are not supported. | |
285 | - Made md5.c use standard memcpy and memset if they are | |
286 | avaliable. | |
287 | - Memory pools will now shrink if Squid is run-time | |
288 | reconfigured with smaller value of memory_pools_limit tag. | |
289 | - Added counter for number of clients (Tomi Hakala). | |
290 | - Changed neighbor UP/DOWN algorithm to require 10 failed TCP | |
291 | connections for UP->DOWN transition. | |
292 | - Added 'unique_hostname' configuration option when its | |
293 | necessary to have multiple machines with the same visible | |
294 | hostname. | |
222917b2 | 295 | - Fixed pumpReadFromClient() to not read too many bytes on |
296 | persistent connections. | |
53856ebd | 297 | - We can now cache HTTP replies with Set-Cookie. These evil |
298 | headers are now filtered out for cache hits on the client | |
299 | side. | |
222917b2 | 300 | - Fixed SNMP bugs caused by using snmpwalk. |
9089cc70 | 301 | - Fixed snmp system Group; all objects are now returned. |
302 | - Fixed snmp system Group sysDescr and sysContact. | |
78dfab2a | 303 | - Fixed snmp system Group sysObjectID it now returns a OBJECT |
304 | IDENTIFIER. | |
7fce9c3e | 305 | - Allocate FwdState from mem pools. |
306 | - Minor HTCP progress. | |
222917b2 | 307 | - Moved 'miss_access' ACL check from client_side.c to forward.c |
ed169eab | 308 | - Fixed logging of usernames for requests which require |
309 | proxy-authentication. | |
cf7f704c | 310 | - Fixed HTTP request parser to accept lowercase HTTP identifier |
311 | (Oskar Pearson). | |
312 | - Fixed FTP listings to always include links to the parent | |
313 | directory (Henrik Nordstrom). | |
314 | - Fixed FTP to show an "empty" listing instead of showing | |
315 | a "document contains no data" error (Henrik Nordstrom). | |
316 | - Fixed refreshCheck() bug. Often it was checking the | |
317 | refresh patterns against the string "[null_mem_obj]" | |
318 | because we moved URLs to MemObject. | |
319 | - Added CARP support by Eric Stern. | |
48382032 | 320 | - Fixed select-spin bug when an ICP reply actually gets queued |
321 | and we failed to execute the write callback. | |
354b5fe1 | 322 | - Fixed a storeCheckSwapOut bug. We were freeing up to |
323 | the queued offset instead of the done offset. This | |
324 | resulted in a small chunk of object data not being in | |
325 | memory and not yet written to disk. A client could | |
326 | recieve a partial object because file_read() unexpectedly | |
327 | returns EOF. | |
0aa791f8 | 328 | - Fixed proxy-authentication hangs (Henrik Nordstrom). |
c2354a6b | 329 | - Fixed request_t->flags bug causing authenticated, proxied |
330 | responses to be cached (Arjan de Vet). | |
e0e32f36 | 331 | - Fixed MIME types for .tgz extension (Henrik Nordstrom). |
332 | - Added view and download options to FTP listings (Henrik | |
333 | Nordstrom). | |
334 | - Modified configure to allow using pre-installed libdlmalloc.a | |
335 | (Masashi Fujita). | |
e8d8856c | 336 | - Fixed cachemgr 'objects' implementation. |
fecf98dc | 337 | - Changed refreshCheck() algorithm. For cached objects, we |
338 | now check, in the following order: | |
339 | * request max-age | |
340 | * response Expires (if present) | |
341 | * refresh_pattern max-age | |
342 | * response Last-Modified compared to refresh_pattern | |
343 | LM-factor (only if Last-Modified is present) | |
344 | * refresh_pattern min-age | |
345 | - Changed Copyrights. | |
d192d11f | 346 | |
ee3a78d4 | 347 | Changes to squid-1.2.beta22 (June 1, 1998): |
348 | ||
2246b732 | 349 | - do not cut off "; parameter" from "digitized" Content-Type |
350 | http fields | |
351 | - Added X-Request-URI for persistent connection debugging | |
352 | (Henrik Nordstrom) | |
f4d83f6d | 353 | - Added Polish error pages from Maciej Kozinski. |
145f10f1 | 354 | - Fixed hash_first/hash_next bugs with **Current pointer. |
355 | Replaced with *next pointer. | |
f4d83f6d | 356 | - Fixed PUT/POST bugs in client (Henrik Nordstrom). |
357 | - Deny forwarding loops in httpd accel mode (Henrik Nordstrom). | |
358 | - Fixed eventRun "spin" bug when event delta time == 0. | |
a9cc1935 | 359 | - Fixed setting Last Modified time on cached entries when |
360 | receiving a 304 reply. | |
06e87923 | 361 | - Added while loop in httpAccept(). |
362 | - Added while loop in icpHandleUdp(). | |
363 | - Fixed some small memory leaks. | |
364 | - Fixed single-bit-int flag checks (Henrik Nordstrom). | |
137ee196 | 365 | - Replaced "complex" (offset accounting) calls to snprintf with MemBuf |
366 | - Do not send only-if-cached cc directive with requests | |
367 | for peer's digests. | |
ee3a78d4 | 368 | - Added "automatic tuning" for incoming request rate, i.e. |
369 | how often to check HTTP and ICP sockets. See comm.c | |
370 | comments for details. | |
145f10f1 | 371 | |
6ee40ea2 | 372 | Changes to squid-1.2.beta21 (May 22, 1998): |
373 | ||
434b408f | 374 | - Added Italian error pages by Alessio Bragadini. |
a3f9588e | 375 | - Added Estonian error pages by Toomas Soome. |
06066bbc | 376 | - Added Russian (koi-r) error pages by Andrew L. Davydov. |
7b381d33 | 377 | - Added Czech error pages by Jakub Nantl. |
8e866bb4 | 378 | - Fixed asnAclInitialize calling to prevent coredump. |
379 | - Fixed FTP directory parsing again. | |
380 | - Made FTP directory listing "Generated" tagline like | |
381 | the one for error pages. | |
52f977aa | 382 | - Fixed an assertion coredump in statHistCopy from |
383 | reconfiguring with different #peers in squid.conf | |
10202788 | 384 | - Ignore leading whitespace on requests (and replies). RFC |
385 | 2068 section 4.1, robustness (Henrik Nordstrom) | |
386 | - Fixed keep_alive bug. We did not always honour reply | |
387 | headers, but rather assumed connections could be persistent. | |
388 | - Fixed reading whois output for AS numbers, especially when | |
389 | they are longer than 4 KB. | |
390 | - Removed 'cache_stoplist_pattern' configuration option. This | |
391 | feature is now handled by 'no_cache'. | |
392 | - If a URN resolves to only one URL, just return it immediately | |
393 | instead of giving the user a "choice" (Andy Powell). | |
394 | - Fixed year-2000 bug in lib/iso3307.c (Henrik Nordstrom). | |
395 | - Changed squid-internal object names. | |

402 | - Added ARP ACL support for Linux (David Luyer). | |
2246b732 | 403 | - Added binary http headers to requests |
99edd1c3 | 404 | - request_t objects are now created and destroyed in a consistent way |
405 | - Fixed cache control printf bug | |
406 | - Added a lot of new http header ids | |
407 | - Improved Connection: header handling; now both Connection and | |
2246b732 | 408 | Proxy-Connection headers are checked for connection directives |
99edd1c3 | 409 | - Connection request header is now handled correctly regardless |
410 | of its position and the number of entries | |
2246b732 | 411 | - Only replies with valid Content-Length can be sent with keep-alive |
412 | connection directive (Henrik Nordstrom) | |
413 | - Better handling of persistent connection "clues" in HTTP headers; | |
414 | the decision now depends on HTTP version (and User-Agent exceptions) | |
99edd1c3 | 415 | - Removed handling of "length=" directive in IMS headers; |
416 | the directive is not in the HTTP/1.1 standard; | |
417 | standing by for objections | |
418 | - allowed/denied headers are now checked using bit masks instead of | |
419 | strcmp loops | |
420 | - removed Uri: from allowed headers; Uri is deprecated in RFC 2068 | |
2246b732 | 421 | - removed processing of Request-Range header (not in specs?) |
7b381d33 | 422 | - Fixed byte-order bugs in cacheDigestHashKey. |
423 | - Changed hash_remove_link() to return void. | |
424 | - Changed ipcache_gethostbyname() to return NULL if | |
425 | i->addrs.count == 0. | |
6de5fa88 | 426 | - Added millisecond-timing to select/poll loops and event |
427 | queue. | |
428 | - Changed 'peerPingTimeout' value to be twice the average | |
429 | of all the peer ICP RTT's. | |
430 | - Added 'half_closed_clients' option to force closing of | |
431 | client connections which might only be half-closed. | |
432 | - Fixed matchDomainName coredump bug. | |
433 | - Don't cache HTTP replies with Vary: headers until we | |
434 | get content negotiation working. | |
435 | - Fixed SSL proxying to forward full HTTP request headers. | |
c09459dd | 436 | - Changed storeGetMemSpace(). Only purge down to the HIGH |
437 | water mark; move locked entries to the head of the inmem | |
438 | list. | |
439 | - Changed clientReadRequest() to locally handle any | |
440 | "squid-internal-static" URL for any host. | |
52f977aa | 441 | - Disable persistent connections for client connections |
442 | from broken Netscape User-Agent, version 3.* (Stewart Forster) | |
434b408f | 443 | |
901b8eaf | 444 | Changes to squid-1.2.beta20 (April 24, 1998): |
445 | ||
fd1bc012 | 446 | - Improved support for only-if-cached cache control directive. |
447 | - Enabled 304 replies for ENTRY_SPECIAL objects (e.g., icons). | |
a1a62b14 | 448 | - Fixed 'quick_abort' percent calculation bug. |
449 | - Fixed quick_abort FPE bug. | |
450 | - Changed more errno-checking functions to use ignoreErrno(). | |
451 | - Added ERESTART to ignoreErrno() because of report from | |
452 | a Solaris system. | |
453 | - Fixed '#elsif' typo. | |
454 | - Fixed MemPool assertion by moving memInit() to before | |
455 | configuration parsing functions. | |
456 | - Fixed default 'announce_period' value (was 1 day, should | |
457 | be 0) (Joe Ramey). | |
458 | - Added configure warning for low filedescriptors and pointer | |
459 | to FAQ. | |
b0497a40 | 460 | - Fixed httpBodySet() bug causing URN related coredumps. |
461 | - Changed ipcacheCycleAddr() to always cycle through all all | |
462 | available addresses, and not just advance when one of | |
463 | them goes BAD. | |
464 | - Fixed squid-internal bug for mixed-case hostnames (Henrik | |
465 | Nordstrom). | |
4e41d49f | 466 | - Fixed ICP counting probelm. icpUdpSend() arg should be |
467 | LOG_ICP_QUERY instead of LOG_TAG_NONE. | |
e4b71f74 | 468 | - Added some additional fault toleranse on FTP data channels |
469 | (Henrik Nordstrom). | |
470 | - Corrected error reporting on FTP "hacks" (Henrik Nordstrom). | |
471 | - Added lock/unlock for StoreEntry during storeAbort(). | |
472 | - Added filemap bit usage stats to cachemgr 'storedir' and | |
473 | 'info'. | |
474 | - Replaced 'cache_stoplist' with 'no_cache' Access list. | |
475 | - Fixed (hopefully) remaining swapfile-open-at-exit bugs. | |
44745828 | 476 | - Fixed default hierarchy_stoplist to be ``default if none.'' |
477 | - Fixed 'fake a recent reply' hack for detecting DEAD | |
478 | and ALIVE neighbors (Joe Ramey). | |
e376562a | 479 | - Fixed FTP directory parsing bugs (Joe Ramey). |
480 | - Fixed ftpTraverseDirectory coredump for NULL ftpState->filepath | |
481 | (Joe Ramey). | |
dea17509 | 482 | - Fixed daylight savings time bug (again). |
fd1bc012 | 483 | - A lot of Cache Digests additions, fixes, and tuning. |
484 | Cache Digests are still "very experimental". | |
e376562a | 485 | - Fixed snprintf() bug. When len == 1, snprintf() would treat |
486 | the buffer as unknown size, emulating sprintf() behaviour. | |
487 | - Made Error page language configurable with configure script | |
488 | (Henrik Nordstrom). | |
489 | - Fixed squid-internal URLs when http_port == 80. | |
490 | - Remember the client address on redirected requests (Henrik | |
491 | Nordstrom). | |
492 | - Don't rebuild the request if the redirector returned the same | |
493 | URL (Henrik Nordstrom). | |
494 | - Rewrite Host: header on redirected requests (Henrik | |
495 | Nordstrom). | |
496 | - Include port (if non-standard) in generated Host: headers | |
497 | (Henrik Nordstrom). | |
498 | - Fixed rfc1123 timezone hacks for Windows NT | |
499 | (Henrik Nordstrom). | |
500 | - Added Russian Error pages by Ilia Zadorozhko. | |
501 | - Added totals for ICP and HTTP hits to cachemgr client_list | |
502 | output. | |
6cfa8966 | 503 | - Changed error message to 'Generated TIME by HOST (SQUID/VER)' |
504 | because any string with an '@' must be an email address. | |
e376562a | 505 | - Fixed POST for content-length == 0. |
901b8eaf | 506 | - Fixed "huge 304 reply" loop bug. |
5e9ab945 | 507 | - Fixed --enable-splaytree compile bugs. |
c93fbf13 | 508 | - Removed ASN lookup code in peer_select.c. |
fd1bc012 | 509 | |
005e5260 | 510 | Changes to squid-1.2.beta19 (Apr 8, 1998): |
511 | ||
b0497a40 | 512 | - Squid-1.2.beta19 compiles and runs on Windows/NT with |
513 | Cygnus Gnu-WIN32 b19 (Henrik Nordstrom). | |
447203a7 | 514 | - Added French Error pages by Frank DENIS. |
515 | - Added Dutch Error pages by Mark Visser | |
901b8eaf | 516 | - Added German Error pages by Bernd P. Ziller, Jens Frank, |
517 | and Anke S. | |
f9f2be04 | 518 | - Added support for only-if-cached cache-control directive. |
005e5260 | 519 | - Added RELAXED_HTTP_PARSER #define to allow requests which are |
520 | missing the HTTP identifier on the request line (e.g. buggy | |
521 | SpyGame queries). RELAXED_HTTP_PARSER is undefined by default. | |
1f4d31f9 | 522 | - Fixed disk.c FD leak for delayed closes in |
523 | diskHandleWriteComplete(). | |
524 | - Fixed cache announcement feature. | |
20fe7191 | 525 | - Fixed httpReadReply() to retry failed HTTP requests on |
526 | persistent connections when read() returns -1, not only | |
527 | when it returns 0. | |
805e5f70 | 528 | - Fixed cbdata memory counting leak. cbdataUnlock() always |
529 | called free(), never memFree(). | |
ff396fe6 | 530 | - Fixed storeDirWriteCleanLogs() malloc bug on Alphas. |
005e5260 | 531 | - Fixed `++loopdetect < 10' assertion due to |
532 | clientHandleIMSReply bug for invalid/partial HTTP | |
533 | replies. | |
534 | - Added preliminary code for HTCP. | |
535 | - Renamed 'aux' dir to 'cfgaux' for legacy DOS machines. | |
536 | - Added "snmp_community" as an ACL type. | |
537 | - Cleaned up proxy-auth acl implementation and removed | |
538 | memory leaks. | |
539 | - Added generic 'hashFreeItems()' function for efficiently | |
540 | freeing hash table pointers. | |
541 | - Added whoisTimeout() for ASN code. | |
447203a7 | 542 | - Removed BINARY TREE code. |
005e5260 | 543 | - Fixed forgetting to reset Config.Swap.maxSize in |
544 | configDoConfigure. | |
545 | - Fixed httpReplyUpdateOnNotModified() arguments-in-wrong-order | |
546 | bug which caused not modified replies to not get updated. | |
547 | - Fixed client_side.c bugs which could cause data to be written | |
548 | to the client in the wrong order for persistent connections. | |
549 | clientPurgeRequest() and clientHandleIMSComplete() must not | |
550 | call comm_write(). Instead they must create and write to | |
551 | StoreEntry's. | |
552 | - Fixed ICP query service time counting bug(s). | |
553 | - replaced 'char *mime_headers_end()' with 'size_t headersEnd()' | |
554 | to fix buffer overruns. This also requires adding 'buf_sz' | |
555 | args to some functions like clientBuildReplyHeader(). | |
556 | But we can eliminate the need to NULL-terminate the | |
557 | buffer beforehand. | |
558 | - Changed commConnectCallback() to reset the FD timeout to | |
559 | zero before notifying about the connection. This requires | |
560 | commSetTimeout() calls in numerous places to reinstall | |
561 | timeouts. | |
562 | - Changed comm_poll_incoming() to be called less frequently | |
563 | (every 15 I/O's instead of every 7 FD's) (Michael O'Reilly). | |
564 | - Removed HAVE_SYSLOG case for debug() macro. Almost all | |
565 | systems do have syslog(), but more importatnly the | |
566 | _db_level value is needed for debugging to stderr. | |
567 | - Rewrote squid/dnsserver interface to use smaller, single-line | |
568 | messages. | |
569 | - Rewrote 'dns' cachemgr output to use a table format. | |
570 | - Rewrote a lot of dnsserver.c. | |
571 | - Added eventAddIsh() for semi-random event scheduling. | |
572 | - Fixed an ftpTimeout bug for sessions which use PORT | |
573 | commands. | |
574 | - Fixed ftp.c to recognized invalid PASV replies (e.g. | |
575 | port == 0). | |
576 | - Removed hash_insert(). All hasing uses hash_join() now. | |
577 | - Renamed hash_unlink() to hash_remove_link(). | |
578 | - Added hashPrime() to find closes prime hash table size | |
579 | to a given value. | |
580 | - Fixed Keep-Alive ratio counting bug which prevented | |
581 | persistent connections from being used between cache | |
582 | peers. | |
583 | - Changed icmp.c to NOT queue messages sent from squid to | |
584 | the pinger program. | |
585 | - Changed icp_v2.c to NOT queue ICP messages by default. | |
586 | But they will be queued and resent once if the first | |
587 | send fails. Counters.icp.queued_replies counts the | |
588 | number of messaages queued. | |
589 | - Cleaned up ICP logging. | |
590 | - Added identTimeout(). | |
591 | - Fixed ipcache reply counting bug. Overcounted dnsserver | |
592 | replies for partial replies. | |
593 | - Added urlInternal() for building internal Squid URLs. | |
594 | - Changed peerAllowedToUse() to check both 'cache_peer_domain' | |
595 | AND 'cache_peer_acl' configurations. This should be changed | |
596 | in the fugure to use ONLY cache_peer_acl. | |
597 | - Changed DEAD/REVIVED neighbor detection to avoid reporting | |
598 | so many false deaths. (Joe Ramey). | |
599 | - Added some preliminary code to support "cache digests." | |
600 | - Fixed pumpClose() coredumps (?). | |
601 | - Updated cachemgr 'info' output to show median service | |
602 | times for various categories. | |
603 | - Fixed ABW bug in storeDirWriteCleanLogs(). sizeof(off_t) | |
604 | != sizeof(int) for Alphas. | |
605 | - Fixed potential alignment problem in storeDirWriteCleanLogs(). | |
606 | - Fixed store_rebuild.c to NOT replace current, but | |
607 | not-swapped-out StoreEntry's with on-disk entries. | |
608 | - Changed storeCleanup() to call storeRelease on invalid | |
609 | entries which don't have a swapfile (i.e. no unlink() | |
610 | penalty). | |
611 | - Fixed storeSwapInStart() to fail for unvalidated | |
612 | entries. | |
613 | - SNMP changes: | |
614 | . renovated mib and added descriptions and comments | |
615 | . added hit and byte counters to client_db , for | |
616 | cacheClientTable | |
617 | . cacheClientTable, netdbTable, cachePeerTable, | |
618 | cacheConnTable now indexed by ip address. hash_lookup was | |
619 | enhanced to allow for subsequent hash_next's similar to | |
620 | hash_first, to speed up getnext's in tables which refer to | |
621 | hash-table structures. | |
622 | . added generic (well, sorf of) table indexing functionality | |
623 | . added makefile dependencies for snmplib and cache_snmp.h | |
624 | . WaisHost, WaisPort, Timeouts removed | |
625 | . FdTable split into FdTable and ConnTable. FdTable simplified | |
626 | . PeerTable and PeerStat merged and put into new cacheMesh | |
627 | group | |
628 | . cacheClientTable added for client statistics and accounting | |
629 | (cacheMesh 2) | |
630 | . cacheSec and cacheAccounting groups removed | |
631 | . fixed acl bug when communities not defined | |
632 | . snmp_acl now survives bad configuration | |
81d0c856 | 633 | |
9a713ffb | 634 | Changes to squid-1.2.beta18 (Mar 23, 1998): |
635 | ||
275d9f2e | 636 | - Added v1.1 'test_reachability' option. |
637 | - Fixed hash4() len == 0 bug. | |
2c26197b | 638 | - Fixed Config.Swap.maxSize reconfigure bug. |
639 | - Fixed ICP query bug determining request method. | |
640 | - Moved ICP's storeGet() cache lookup into neighborsUdpAck() | |
641 | so that we know neighbors are alive even when they send | |
642 | us replies for unknown entries. | |
643 | - Changed configure script to add '-std1' for Digital Unix cc. | |
644 | - Fixed SNMP sizeof(int) / sizeof(long) bugs for 64-bit | |
645 | systems. | |
646 | - Added support for 'Cache-Control: Only-If-Cached' request header. | |
34ad1721 | 647 | - Fixed CheckQuickAbort() bugs for multiple clients on one |
648 | StoreEntry. Also changed storePendingNClients() to return | |
649 | mem->nclients instead of counting the number of store_client | |
650 | entries with pending callback functions. | |
275d9f2e | 651 | |
041b157e | 652 | Changes to squid-1.2.beta17 (Mar 17, 1998): |
653 | ||
df43fc93 | 654 | - SNMP MIB version check changed to non-rcs. |
02922e76 | 655 | - Added memory pools for variable size objects (strings). |
656 | There are three pools; for small, medium, and large objects. | |
657 | - Extended String object to use memory pools. Most fixed size char | |
658 | array fields will be replaced using string pools. Same for most | |
659 | malloc()-ed buffers. | |
5e14bf6d | 660 | - Changed icon handling to use the hostname and port of the squid |
9ed90c85 | 661 | server, instead of the special hostname "internal.squid" |
662 | (Henrik Nordstrom). | |
5e14bf6d | 663 | - All icons are now configured in mime.conf. No hardcoded icons, |
f8360ee3 | 664 | including gohper icons (Henrik Nordstrom). |
459f2559 | 665 | - Fixed ICP bug when we send queries, but expect zero |
666 | replies. | |
ed9c0b33 | 667 | - Fixed alignment/casting bugs for ICP messages. |
2b5b6324 | 668 | - A generic client-to-server "pump" was added to handle HTTP |
669 | PUT as well as POST methods on the client-cache side. Based on | |
670 | "pump" PUT requests can be made to either HTTP or FTP url's. | |
671 | Code is still beta and interoperability with browsers etc has | |
672 | not been tested. | |
673 | - Put #ifdefs around 'source_ping' code. | |
5e14bf6d | 674 | - Added missing typedef for _arp_ip_data (Wesha). |
675 | - Added regular-expression-based ACLs for client and server | |
676 | domain names (Henrik Nordstrom). | |
677 | - Fixed ident-related coredumps from incorrect callback data. | |
678 | - Fixed parse_rfc1123() "space" bug. | |
679 | - Fixed xrealloc() XMALLOC_DEBUG bug (not calling check_free()).. | |
680 | - Fixed some src/asn.c end-of-reply bugs and memory leaks. | |
681 | - Fixed some peer->options flag-setting bugs. | |
682 | - Fixed single-parent feature to work again | |
683 | - Removed 'single_parent_bypass' configuration option; instead | |
684 | just use 'no-query'. | |
685 | - Surrounded 'source_ping' code with #ifdefs. | |
686 | - Changed 'deny_info URL' to use a custom Error page. | |
687 | - Modified src/client.c for testing POST requests. | |
041b157e | 688 | - Fixed hash4() for SCO (Vlado Potisk). |
459f2559 | 689 | |
7ba777f2 | 690 | Changes to squid-1.2.beta16 (Mar 4, 1998): |
691 | ||
447203a7 | 692 | - Added Spanish error messages from Javier Puche. |
02922e76 | 693 | - Added Portuguese error messages from Pedro Lineu Orso |
0965bd19 | 694 | - Added a simple but very effective hack to cachemgr.cgi that tries to |
695 | interpret lines with '\t' as table records and formats them | |
696 | accordingly. With a few exceptions (see source code), first line | |
697 | becomes a table heading ("<th>" html tag) and the rest is formated | |
698 | with "<td>" tags. | |
7021844c | 699 | - Added "mem_pools_limit" configuration option. Semantics of |
700 | "mem_pools" option has also changed a bit to reflect new memory | |
701 | management policy. | |
7ba777f2 | 702 | - Reorganized memory pools. Squid now supports a global pool |
703 | limit instead of individual pool limits. Per-pool limits can be | |
3a88d597 | 704 | implemented on top of the current scheme if needed, but it is |
7ba777f2 | 705 | probably hard to guess their values. Squid distributes pool |
706 | memory among "frequently allocated" objects. There is a | |
707 | configurable limit on the total amount of "idle" memory to be | |
708 | kept in reserve. All requests that exceed that amount are | |
709 | satisfied using malloc library. Support for variable size | |
710 | objects (mostly strings) will be enabled soon. | |
711 | - memAllocate() has now only one parameter. Objects are always | |
712 | reset with 0s. (We actually never used that parameter before; | |
713 | it was always set to "clear"). | |
714 | - Added Squid "signature" to all ERR_ pages. The signature is | |
715 | hardcoded and is added on-the-fly. The signature may use | |
716 | %-escapes. Added interface to add more hard-coded responses if | |
717 | needed (see errorpage.c::error_hard_text). | |
718 | - Both default and configured directories are searched for ERR_ | |
719 | pages now. Configured directory is, of course, searched first. | |
720 | This allows you to customize a subset of ERR_ pages (in a | |
721 | separate directory) without danger of getting other copies out | |
722 | of sync. | |
723 | - Security controls for the SNMP agent added. Besides | |
724 | communities (like password) and views (part of tree | |
725 | accessible), the snmp_acl config option can be used to do acl | |
726 | based access checks per community. | |
727 | - SNMP agent was heavily re-written, based on cmu-snmpV1.8. You | |
728 | can now walk through the whole mib tree. Several new variables | |
729 | added under cacheProtoAggregateStats | |
12cf1be2 | 730 | - Added rudimental statistics for HTTP headers. |
7ba777f2 | 731 | - Adjusted StatLogHist to a more generic/flexible StatHist. |
12cf1be2 | 732 | Moved StatHist implementation into a separate file. |
178dbda2 | 733 | - Added FTP support for PORT if PASV fails, also try the |
734 | default FTP data port (Henrik Nordstrom). | |
735 | - Fixed NULL pointer bug in clientGetHeadersForIMS when a | |
736 | request is cancelled for fails on the client side. | |
737 | - Filled in some squid.conf comments (never_direct, | |
738 | always_direct). | |
739 | - Added RES_DNSRCH to dnsserver's _res.options when the | |
740 | -D command line option is given. | |
741 | - Fixed repeated Detected DEAD/REVIVED Sibling messages when | |
742 | peer->tcp_up == 0 (Michael O'Reilly). | |
743 | - Fixed storeGetNextFile's incorrect "directory does not exist" | |
744 | errors (Michael O'Reilly). | |
745 | - Fixed aiops.c race condition (Michael O'Reilly, Stewart | |
746 | Forster). | |
747 | - Added 'dns_nameservers' config option to specify non-default | |
748 | DNS nameserver addresses (Maxim Krasnyansky). | |
749 | - Added lib/util.c code to show memory map as a tree | |
750 | (Henrik Nordstrom). | |
751 | - Added HTTP and ICP median service times to Counters and | |
752 | cachemgr average stats. | |
753 | - Changed "-d" command line option to take debugging level | |
754 | as argument. Debugging equal-to or less-than the argument | |
755 | will be written to stderr. | |
ef65d6ca | 756 | - Removed unused urlClean() function from url.c. |
adba4a64 | 757 | - Fixed a bug that allowed '?' parts of urls to be recorded in |
ef65d6ca | 758 | store.log. Logged urls are now "clean". |
178dbda2 | 759 | - Cache Manager got new Web interface (cachemgr.cgi). New .cgi |
760 | script forwards basic authentication from browser to squid. | |
761 | Authentication info is encoded within all dynamically generated | |
762 | pages so you do not have to type your password often. | |
763 | Authentication records expire after 3 hours (default) since | |
764 | last use. Cachemgr.cgi now recognizes "action protection" types | |
765 | described below. | |
766 | - Added better recognition of available protection for actions | |
767 | in Cache Manager. Actions are classified as "public" (no | |
768 | password needed), "protected" (must specify a valid password), | |
769 | "disabled" (those with a "disable" password in squid.conf), and | |
770 | "hidden" (actions that require a password, but do not have | |
771 | corresponding cachemgr_passwd entry). If you manage to request | |
772 | a hidden, disabled, or unknown action, squid replies with | |
773 | "Invalid URL" message. If a password is needed, and you failed | |
774 | to provide one, squid replies with "Access Denied" message and | |
775 | asks you to authenticate yourself. | |
776 | - Added "basic" authentication scheme for the Cache Manager. | |
777 | When a password protected function is accessed, Squid sends an | |
778 | HTTP_UNAUTHORIZED reply allowing the client to authorize itself | |
779 | by specifying "name" and "password" for the specified action. | |
780 | The user name is currently used for logging purposes only. The | |
781 | password must be an appropriate "cachemgr_passwd" entry from | |
782 | squid.conf. The old interface (appending @password to the url) | |
783 | is still supported but discouraged. Note: it is not possible | |
784 | to pass authentication information between squid and browser | |
785 | *via a web server*. The server will strip all authentication | |
786 | headers coming from the browser. A similar problem exists for | |
787 | Proxy-Authentication scheme. | |
788 | - Added ERR_CACHE_MGR_ACCESS_DENIED page to notify of | |
789 | authentication failures when accessing Cache Manager. | |
63259c34 | 790 | - Added "-v" (Verbose) and "-H" (extra Headers) options to client.c. |
178dbda2 | 791 | - Added simple context-based debugging to debug.c. Currently, |
792 | the context is defined as a constant string. Context reporting | |
793 | is triggered by debug() calls. Context debugging routines | |
794 | print minimal amount of information sufficient to describe | |
795 | current context. The interface will be enhanced in the future. | |
796 | - Replaced _http_reply with HttpReply. HttpReply is a | |
797 | stand-alone object that is responsible for parsing, swapping, | |
798 | and comm_writing of HTTP replies. Moved these functions from | |
799 | various modules into HttpReply module. | |
8bfcd557 | 800 | - Added HttpStatusLine, HttpHeader, HttpBody. |
178dbda2 | 801 | - All HTTP headers are now parsed and stored in a "compiled" |
802 | form in the HttpHeader object. This allows for a great | |
803 | flexibility in header processing and builds basis for support | |
804 | of yet unsupported HTTP headers. | |
805 | - Added Packer, a memory/store redirector with a printf | |
806 | interface. Packer allows to comm_write() or swap() an object | |
807 | using a single routine. | |
808 | - Added MemBuf, a auto-growing memory buffer with printf | |
809 | capabilities. MemBuf replaces most of old local buffers for | |
810 | compiling text messages. | |
811 | - Added MemPool that maintains a pre-allocated pool of opaque | |
812 | objects. Used to eliminate memory thrashing when allocating | |
813 | small objects (e.g. field-names and field-value in http | |
814 | headers). | |
8bfcd557 | 815 | |
3197e644 | 816 | Changes to squid-1.2.beta15 (Feb 13, 1998): |
817 | ||
55647891 | 818 | NOTE: This version has changes which may cause all or part |
819 | of your cache to be lost. However, you can problably | |
820 | save most of it by doing a slow restart. Specifically: | |
821 | ||
822 | 1. Kill the running squid-1.2.beta14 process; wait for it to | |
823 | fully exit. | |
824 | 2. Remove all 'swap.state*' files, either in each cache_dir, or | |
825 | as defined in your squid.conf | |
826 | 3. Start squid-1.2.beta15. The store will be rebuilt from the | |
827 | existing swap files, reading the directories and opening | |
828 | the files. | |
829 | ||
bcfbdc11 | 830 | - Fixed some problems related to disk (and pipe) write error |
831 | handling. file_close() doesn't always close the file | |
832 | immediately; i.e. when there are pending buffers to write. | |
833 | StoreEntry->lock_count could become zero while a write is | |
834 | pending, then bad things happen during the callback. | |
835 | - The file_write() callback data must now be in the callback | |
836 | database (cbdata). We now use the swapout_ctrl_t structure | |
837 | for the callback data; it stays around for as long as we are | |
838 | swapping out. | |
839 | - Changed the way write errors are handled by diskHandleWrite. | |
840 | If there is no callback function, now we exit with a fatal | |
841 | message under the assumption that the file in question is a | |
842 | log file or IPC pipe. Otherwise, we flush all the pending | |
843 | write buffers (so we don't see multiple repeated write errors | |
844 | from the same descriptor) and let the upper layer decide how | |
845 | to handle the failure. | |
846 | - Fixed storeDirWriteCleanLogs. A write failure was leaving | |
847 | some empty swap.state files, even though it tells us that its | |
848 | "not replacing the file." Don't flush/rename logs which we | |
849 | have prematurely closed due to write failures, indiciated by | |
850 | fd[dirn] == -1. Close these files LAST, not before | |
851 | renaming. | |
852 | - Fixed storeDirClean to clean directories in a more sensible | |
853 | order, instead of the new "MONOTONIC" order for swap files. | |
0465e406 | 854 | - Merged fdstat.c functions into fd.c. |
855 | - Cleaned up some debugging sections. Some unrelated source | |
856 | files were using the same section. | |
857 | - Removed curly brackets from all cachemgr output. | |
858 | - Removed unused filemap->last_file_number_allocated member. | |
859 | - Removed unused fde->lifetime_data member. | |
860 | - Fixed incorrectly applying htonl() on icp_common_t->shostid. | |
861 | - Call setsid() before exec() in ipc.c so that child processes | |
862 | don't receive SIGINT (etc) when running squid on a tty. | |
2f2dd5ad | 863 | - Changed StoreEntry->object_len to ->swap_file_sz so we |
864 | can verify the disk file size at restart. Moved object_len | |
865 | to MemObject->object_sz. Note object_sz is initialized | |
866 | to -1. If object_sz < 0, then we need to open the swap | |
867 | file and read the swap metadata. | |
868 | - Changed store_client->mem to ->entry because we need | |
869 | e->swap_file_sz to set mem->object_sz at swapin. | |
2f2dd5ad | 870 | - Renamed storeSwapData structure to storeSwapLogData. |
871 | - Fixed storeGetNextFile to not increment d->dirn. Added | |
872 | check for opendir() failure. | |
873 | - Fixed storeRebuildStart to properly link the directory | |
874 | list for storeRebuildfromDirectory mode. | |
e157f97f | 875 | - Added -S command line option to double-check store |
876 | consistency with disk files in storeCleanup(). | |
877 | - Fixed a problem with transactional logging. In many | |
878 | cases we were adding the public cache key and then | |
879 | logging a delete for the private key. This is worthless | |
880 | because during rebuild we could not locate the previous | |
881 | public-keyed entry. Now we assert that only public-keyed | |
882 | entries can be logged to swap.state. storeSetPublicKey() | |
883 | and storeSetPrivateKey() have been modified to log an | |
884 | ADD or DEL when the key changes. | |
885 | - Fixed storeDirClean bug. Needed to call | |
886 | storeDirProperFileno() so the "dirn bits" get set. | |
887 | - Fixed a storeRebuildFromDirectory bug. fullpath[] and | |
888 | fullfilename[] were static to that function and did | |
889 | not change when the "rebuild_dir" arg did. Moved these | |
890 | buffers to the rebuild_dir structure. | |
891 | - In storeRebuildFromSwapLog, we were calling storeRelease() | |
892 | for cache key collisions. This only set the RELEASE_REQUEST | |
893 | bit and did not clear the swap_file_number in the filemap or | |
894 | in the StoreEntry, so the swap file could get unlinked later | |
895 | when it was really released. | |
4e0f0471 | 896 | - Fixed FTP so that ';type=X' specifically sets the HTTP reply |
897 | content-type and content-encoding (Henrik Nordstrom). | |
898 | - Removed 'icon_content_type' configuration option. Content | |
899 | types now taken from mime.conf (Henrik Nordstrom). | |
2a9b2b73 | 900 | - Added additional memory malloc tracing and memory leak |
901 | detection. Use --enable-xmalloc-debug-trace configure | |
902 | option and -m command line option (Henrik Nordstrom). | |
bcfbdc11 | 903 | |
93169941 | 904 | Changes to squid-1.2.beta14 (Feb 6, 1998): |
905 | ||
5471db88 | 906 | - Replaced snmplib free() calls with xfree(). |
907 | - Changed the 'net_db_name' hash table structure to | |
908 | make it easier to move names from one network to another | |
909 | (copied from 1.1 code). | |
93169941 | 910 | - Filled in some of the config dump routines (dump_acl, |
911 | dump_acl_access). | |
912 | - Full memory debugging option (--enable-xmalloc-debug-trace) | |
913 | (Henrik Nordstrom). | |
914 | - Filled-in and clarified many squid.conf comments (Oskar | |
915 | Pearson). | |
916 | - Fixed up handling of SWAP_LOG_DEL swap.state entries. | |
5471db88 | 917 | |
f91834bf | 918 | Changes to squid-1.2.beta13 (Feb 4, 1998): |
f577e074 | 919 | |
b4512acd | 920 | - NOTE: With this version the "swap.state" file format has |
921 | changed. Running this version for the first time will | |
922 | cause your current cache contents to be lost! | |
f91834bf | 923 | - NOTE: this version still has the bug where we don't rewind |
924 | a swapout file and rewrite the swap meta data. Objects | |
925 | larger than 8KB will be lost when rebuilding from the swap | |
926 | files. | |
d04dd4bf | 927 | - Combined various interprocess communication setup functions |
928 | into ipcCreate(). | |
929 | - Removed some leftover ICP_HIT_OBJ things. | |
930 | - Removed cacheinfo and proto_count() and friends; these are to | |
931 | be replaced in functionality by StatCounters and 5/60 minute | |
932 | average views via cachemgr. | |
933 | - Fixed --enable-acltree configure message (Masashi Fujita). | |
934 | - Fixed no reference to @LIB_MALLOC@ in src/Makefile.in | |
935 | (Masashi Fujita). | |
936 | - Fixed building outside of source tree (Masashi Fujita). | |
dbfed404 | 937 | - FTP: Format NLST listings, and inform the user that the NLST |
938 | (plain) format is available when we find a LIST listing that we | |
939 | don't understand (Henrik Nordstrom) | |
940 | - FTP: Use SIZE on Binary transfers, and not ASCII. The | |
941 | condition was inversed, making squid use SIZE on ASCII | |
942 | transfers (Henrik Nordstrom). | |
943 | - Enable virtual and Host: based acceleration in order to be | |
944 | able to use Squid as a transparent proxy without breaking | |
945 | either virtual servers or clients not sending Host: header | |
946 | the order of the virtual and Host: based acceleration needs | |
947 | to be swapped, giving Host: a higher precendence than virtual | |
948 | host (Henrik Nordstrom). | |
949 | - Use memmove/bcopy as detected by configure Some systems does | |
950 | not have memmove, but have the older bcopy implementation | |
951 | (Henrik Nordstrom). | |
6cf028ab | 952 | - Completely rewritten aiops.c that creates and manages a pool |
953 | of threads so thread creation overhead is eliminated (SLF). | |
954 | - Lots of mods to store.c to detect and cancel outstanding | |
955 | ASYNC ops. Code is not proven exhaustive and there are | |
956 | definately still cases to be found where outstanding disk ops | |
957 | aren't cancelled properly (SLF). | |
958 | - Changes to call interface to a few routines to support disk | |
959 | op `tagging', so operations can be cleanly cancelled on | |
960 | store_abort()s (SLF). | |
961 | - Implementation of swap.state files as transaction logs. | |
962 | Removed objects are now noted with a negative object size. | |
963 | This allows reliatively clean rebuilds from non-clean | |
964 | shutdowns (SLF). | |
965 | - Now that the swap.state files are transaction logs, there's | |
966 | now no need to validate by stat()ing. All the validation | |
967 | procedure does is now just set the valid bit AFTER all the | |
968 | swap.state files have been read, because by that time, only | |
969 | valid objects can be left. Object still need to be marked | |
970 | invalid when reading the swap.state file because there's no | |
971 | guarantee the file has been retaken or deleted (SLF). | |
972 | - An fstat() call is now added after every | |
973 | storeSwapInFileOpened() so object sizes can be checked. Added | |
974 | code to storeRelease() the object if the sizes don't match (SLF). | |
975 | - #defining USE_ASYNC_IO now uses the async unlink() rather than | |
976 | unlinkd() (SLF). | |
977 | - #defining MONOTONIC_STORE will support the creation of disk | |
978 | objects clustered into directories. This GREATLY improves disk | |
979 | performance (factor of 3) over old `write-over-old-object' | |
980 | method. If using the MONOTONIC_STORE, the | |
981 | {get/put}_unusedFileno stack stuff is disabled. This is | |
982 | actually a good thing and greatly reduces the risk of serving | |
983 | up bad objects (SLF). | |
984 | - Fixed unlink() in storeWriteCleanLogs to be real unlink() | |
985 | rather than ASYNC/unlinkd unlinks. swap.state.new files were | |
986 | being removed just after they were created due to delayed | |
987 | unlinks (SLF). | |
988 | - Disabled various assertions and made these into debug warning | |
989 | messages to make the code more stable until the bugs can be | |
990 | tracked down (SLF). | |
991 | - Added most of Michael O'Reilly's patches which included many | |
992 | bug fixes. Ask him for full details (SLF). | |
993 | - Moved aio_check_callbacks in comm_{poll|select}(). It was | |
994 | called after the fdset had been built which was wrong because | |
995 | the callbacks were changing the state of the read/write | |
996 | handlers prior to the poll/select() calls (SLF). | |
f09f5b26 | 997 | - Fixed ARP ACL memory leaks (Dale). |
f577e074 | 998 | - Eliminated URL and SHA cache keys. Cache keys will always |
999 | be MD5's now. | |
1000 | - Fixed up store swap meta data. | |
1001 | - Changed swap.state logs to a binary format. | |
f91834bf | 1002 | - The swap.state logs are written transaction-style. |
d04dd4bf | 1003 | |
b5cfbd5b | 1004 | Changes to squid-1.2.beta12 (Jan 30, 1998): |
1005 | ||
b4512acd | 1006 | - Added metadata headers to cache swap files. This is an |
1007 | incompatible change with previous versions. Running this | |
1008 | version for the first time will cause your current cache | |
1009 | contents to be lost. | |
9fc0b4b8 | 1010 | - -D_REENTRANT when linking with -lpthreads (Henrik Nordstrom) |
1011 | - Show symlink destinations as a hyperlink in FTP listings | |
1012 | (Henrik Nordstrom) | |
3a4eaced | 1013 | - Fixed not allocating enough space for rewriting URLs with |
1014 | the Host: header (Eric Stern). | |
1015 | - Year-2000 fixes (Arjan de Vet). | |
1016 | - Fixed looping for cache hits on HEAD requests. | |
fc6dc767 | 1017 | - Fixed parseHttpRequest() coredump for |
1018 | "GET http://foo HTTP/1.0\r\n\r\n\r\n" | |
9fc0b4b8 | 1019 | |
9f802cb1 | 1020 | Changes to squid-1.2.beta11 (Jan 6, 1998): |
1021 | ||
fd82d0b0 | 1022 | - Fixed fake 'struct rusage' definition which prevented compling |
1023 | on Solaris 2.4. | |
1024 | - Fixed copy-by-ref bug for request->headers in | |
1025 | clientRedirectDone() (Michael O'Reilly). | |
812db943 | 1026 | - Workaround for Solaris pthreads closing FD 0 upon fork() |
1027 | (Michael O'Reilly). | |
05fd71a7 | 1028 | - Fixed shutdown bug with outgoing UDP sockets; we need to |
1029 | disable their read handlers. | |
1030 | - For comm_poll(), use the fast 50 msec timeout only when | |
1031 | USE_ASYNC_IO is defined. | |
1fbc6de3 | 1032 | - Fixed pointer bug when freeing AS# ACL entries. |
1033 | - Fixed forgetting to reset Config.npeers to zero in free_peer(). | |
0f6bdbfa | 1034 | - Fixed ICP bug causing excessive TIMEOUTs with sibling |
1035 | neighbors. We must call the ICP reply callback even for | |
1036 | sibling misses. | |
1037 | - Fixed some dnsserver-related reconfigure bugs. Need to | |
1038 | use cbdataLock, etc in fqdncache.c. Also don't want to | |
1039 | use ipcacheQueueDrain() and fqdncacheQueueDrain(). | |
1040 | - Fixed persistent connection bug. We were incorrectly | |
1041 | deciding that non-200 replies without content-length | |
1042 | would not have a reply body. | |
1043 | - Fixed intAverage() precedence bug. | |
1044 | - Fixed memmove() 'len' arg bug. | |
1045 | - Changed algorithm for determining alive/dead state of peers. | |
1046 | Instead of using a fixed number of unacknowledged ICP | |
1047 | replies, it is now based on timeouts. If there are no ICP | |
1048 | replies received from a peer within 'dead_peer_timeout' | |
1049 | seconds, then we call it dead. | |
1050 | - Added calls to getCurrentTime() in | |
1051 | comm_{select,poll}_incoming() when ALARM_UPDATES_TIME is not | |
1052 | being used. | |
1053 | - Fixed shutdown bug when the incoming and outgoing ICP socket | |
1054 | is the same file descriptor. | |
e970f357 | 1055 | - Added buffered writes for storeWriteCleanLogs() (Stewart |
1056 | Forster). | |
1057 | - Patches for Qnx4 (Jean-Claude MICHOT). | |
1058 | - Fixed returning void functions which seems to be a GCC-ism. | |
e5f4e1b0 | 1059 | - New configure script options (Henrik Nordstrom): |
1060 | --enable-new-storekey=[sha|md5(|url)] (was --enable-hashkey) | |
1061 | --enable-acltree | |
1062 | --enable-icmp | |
1063 | --enable-delay-hack | |
1064 | --enable-useragent-log | |
1065 | --enable-kill-parent (this should be named -hack) | |
1066 | --enable-snmp | |
1067 | --enable-time-hack | |
1068 | --enable-cachemgr-hostname[=hostname] (new) | |
1069 | --enable-arp-acl (new) | |
1070 | - Added Doug Lea malloc-2.6.4 to the distribution, so that | |
1071 | people easily can try a decent malloc package if they syspect | |
1072 | their malloc is broken. --enable-dlmalloc (Henrik Nordstrom). | |
1073 | - Made XMALLOC_DEBUG_COUNT working again. Requires a small stub | |
1074 | function (Henrik Nordstrom). | |
1075 | - Removed top-level Makefile. People must now run 'configure' | |
1076 | before 'make'. | |
714ace98 | 1077 | - Fixed checkFailureRatio() implementation. |
82b3c7d9 | 1078 | - Made 'squid -z' behave like the 1.1 version. |
e5f4e1b0 | 1079 | |
fd82d0b0 | 1080 | |
ab9a3f7e | 1081 | Changes to squid-1.2.beta10 (Jan 1, 1998): |
1082 | ||
1083 | - Fixed content-length bugs for 204 replies, 304 replies, | |
1084 | and HEAD requests (Henrik Nordstrom). | |
1085 | - Fixed errorAppendEntry() bug in gopherReadReply(). | |
1086 | - Basic support for FTP URL typecodes (;type=X). | |
9c965c1b | 1087 | - Support for access controls based on ethernet MAC addresses |
ab9a3f7e | 1088 | (Dale). |
1089 | - Initial URN support; see | |
1090 | http://squid.nlanr.net/Squid/urn-support.html | |
1091 | - Fixed client-side persistent connections for objects with | |
1092 | bad content lengths (Henrik Nordstrom). | |
1093 | - Fixed bad call to storeDirUpdateSwapSize() for objects which | |
1094 | never reach SWAPOUT_DONE state. | |
68e3a9df | 1095 | - Fixed up poll() #defines in squid.h (Stewart Forster). |
1096 | - Changed poll() timeout from 1000 msec to 50 msec for | |
1097 | better performance under low load (Stewart Forster). | |
e7a1fde6 | 1098 | - Changed storeWriteCleanLogs() to write objects in the LRU |
1099 | list order instead of the random hash table order. | |
109ff6af | 1100 | - Fixed FTP bug when data socket connections fail or timeout. |
1101 | - Reuse FTP data connection when possible (Henrik Nordstrom). | |
1102 | - Added configure options (Henrik Nordstrom) | |
1103 | --enable-store-key=sha|md5 | |
1104 | --enable-xmalloc-statistics | |
1105 | --enable-xmalloc-debug | |
78743365 | 1106 | --enable-xmalloc-debug-count |
1107 | --async-io | |
109203bf | 1108 | - Fixed confusing with the use/meaning of ERR_CANNOT_FORWARD |
1109 | by creating ERR_FORWARDING_DENIED and changing the | |
1110 | content of the ERR_CANNOT_FORWARD text. | |
4e9c07c1 | 1111 | - Fixed pipeline request bug from using strdup() (Henrik |
1112 | Nordstrom). | |
1113 | - Call clientReadRequest() directly instead of commSetSelect() | |
1114 | for pipelined requests (Henrik Nordstrom). | |
1b02b5be | 1115 | - Fixed 4k page leak in icpHandleIMSReply(); |
1116 | - Renamed 'icp*' functions to 'client*' names in client_side.c. | |
e7a1fde6 | 1117 | |
b90a0f8d | 1118 | Changes to squid-1.2.beta8 (Dec 2, 1997): |
1119 | ||
eae03fc8 | 1120 | - Fixed accessLogLog() to log ident from Proxy-Authorization |
1121 | request header (BoB Miorelli). | |
226f9ba2 | 1122 | - Fixed #includes, prototypes, etc. in SNMP source files. |
1123 | - Moved 'POLLRDNORM' and 'POLLWRNORM' macro checks from | |
1124 | include/config.h.in to src/squid.h | |
1125 | - Moved 'num32' typedefs from src/typedefs.h to | |
1126 | include/config.h.in. | |
1127 | - Moved snmplib/md5.c to lib/md5.c. | |
1128 | - Added MD5 cache key support. | |
1129 | - Removed xmalloc() return check in uudeocde.c | |
1130 | - Added 'ifdef' support to cf_gen.c for optional code (e.g. SNMP) | |
1131 | - Changed 'client' program to provide easier cache manager access, | |
1132 | e.g.: 'client mgr:info' | |
1133 | - Fixed 'client' to send 'Connection' instead of 'Proxy-Connection' | |
1134 | for simulated keep-alive requests. | |
1135 | - Removed 'fd' arg from clientProcess* functions. | |
9e3468d5 | 1136 | - Fixed bugs from using errorSend() on persistent/pipelined |
226f9ba2 | 1137 | client connections. A latter request should not be allowed to |
1138 | write to the client fd until the current request completes. | |
1139 | Now use errorAppendEntry() for such situations. | |
1140 | - Fixed content-length bugs. We were using content-length == 0 | |
1141 | to also indicate a lack of content-length reply header. But | |
1142 | 'content-length: 0' might appear in a reply, so now use -1 to | |
1143 | indicate that no content length given. | |
1144 | - Split up clientProcessRequest() into smaller chunks so it | |
1145 | might be easier to follow. | |
1146 | - renamed various client_side.c functions to start with 'client' | |
1147 | instead of 'icp'. | |
1148 | - Fixed a 'cbdata leak' from the comm.c close handlers. | |
1149 | - Fixed a 'cbdata leak' from the comm.c connect routines. | |
1150 | - Fixed comm_select() and comm_poll() to stop looping on the | |
1151 | incoming HTTP/ICP sockets. If there are fewer than 7 FD's | |
1152 | ready for I/O, the incoming sockets might not get service, so | |
1153 | comm_select() would be called for up to 7 times until the | |
1154 | 'incoming_counter' was incremented enough to trigger a call | |
1155 | to comm_select_incoming(). Now we make sure | |
1156 | comm_select_incoming() gets called if select returns less | |
1157 | than 7 ready FD's. | |
9e3468d5 | 1158 | - Added errorpage '%B' token to generate FTP URLs with a '%2f' |
1159 | inserted at the start of the url-path. calls ftpUrlWith2f(). | |
1160 | (Henrik Nordstrom). | |
226f9ba2 | 1161 | - Changed fqdncache.c to use LRU double-linked list instead of qsort() |
1162 | for replacement and cachemgr output. | |
1163 | - Changed ipcache.c to use LRU double-linked list instead of qsort() | |
1164 | - Changed hash_insert() and hash_join() to return void. | |
1165 | for replacement and cachemgr output. | |
1166 | - Moved StoreEntry->method member to MemObject->method. | |
1167 | - Made StoreEntry->flags 16 bits. | |
1168 | - Made StoreEntry->refcount 16 bits. | |
1169 | - Changed URL-based public cache key to always include the request | |
1170 | method. | |

95bc9f0b | 1172 | Changes to squid-1.2.beta7 (Nov 24, 1997): |
1173 | ||
6a11653c | 1174 | - Fixed poll() for Linux (David Luyer). |
1175 | - SHA optimizations (David Luyer). | |
1176 | - Fixed errno clashes with macro on Linux (David Luyer). | |
1177 | - Fixed storeDirCloseSwapLogs(); logs might not be open. | |
1178 | - Fixed storeClientCopy2() bug. Detect when there is | |
1179 | no more data to send for objects in STORE_OK state. | |
19ee64b1 | 1180 | - Fixed FTP truncation bug when ftpState->size == 0, e.g. |
1181 | especially directory listings. | |
95bc9f0b | 1182 | - Mega FTP fix from Henrik Nordstrom. A better job of |
1183 | implementing the '%2f' hack. | |
1184 | - Fixed some pipelined request bugs. storeClientCopy() was | |
1185 | being given the wrong StoreEntry, and we had a race condition | |
1186 | which is now handled by storeClientCopyPending(). | |
99077fe6 | 1187 | - Added initial SNMP support. |
6a11653c | 1188 | |
2c9b45c9 | 1189 | Changes to squid-1.2.beta6 (Nov 13, 1997): |
1190 | ||
1b5516d3 | 1191 | - Fixed Authorized responses getting swapped out when they |
1192 | don't have Proxy-Revalidate reply header. | |
1193 | - Fixed Proxy Authentication support. We never sent back | |
1194 | a 407 reply, and were incorrectly incrementing the passwd | |
1195 | before comparing it. | |
1196 | - Fixed stat()ing pathnames for default values before parsing | |
1197 | config file (Ron Gomes). | |
1198 | - Fixed logging request and response headers on separate lines | |
1199 | (Ron Gomes). | |
1200 | - Fixed FTP Authentication message (Henrik Nordstrom). | |
1201 | - Changed Proxy Authentication to trigger a reread of the passwd | |
1202 | file if a password check fails (Henrik Nordstrom). | |
1203 | - Changed FTP to retry the first CWD with a leading slash if it | |
1204 | fails without one. | |
1205 | ||
8c17a569 | 1206 | Changes to squid-1.2.beta5 (Nov 6, 1997): |
1207 | ||
90045285 | 1208 | - Track the 'keep-alive ratio' for a peer as the ratio of |
1209 | the number of replies including 'Proxy-Connection: Keep-Alive' | |
1210 | compared to the number of requests sent. If the peer does | |
1211 | not support Persistent connections then this ratio will tend | |
1212 | toward zero. If the ratio is less than 50% after 10 requests | |
1213 | then we'll stop sending Keep-Alive. | |
8c3994aa | 1214 | - Proper support for %nn escapes in FTP, and numerous |
1215 | other fixes (Henrik Nordstrom). | |
1216 | - Support for Secure Hash Algorithm and framework for other | |
1217 | hash functions as cache keys. | |
1218 | - Fixed SSL snprintf() bug which broke SSL proxying. | |
1219 | - Fixed store_dir swap log bug from reconfigure (SIGHUP). | |
8c17a569 | 1220 | - Fixed LRU Reference Age bug. The arg to pow() must be |
8031bd43 | 1221 | minutes, not seconds. |
90045285 | 1222 | |
9ddfb255 | 1223 | Changes to squid-1.2.beta4 (Oct 30, 1997): |
1224 | ||
a493f974 | 1225 | - Fixed DST bug in rfc1123.c |
1226 | - Changed default http_accel_port to 80. | |
1227 | - added errorCon() as a ErrorState constructor function | |
1228 | (Max Okumoto). | |
1229 | - Added ERR_FTP_FAILURE message for ftpFail(). | |
1230 | - For FTP, the timeout callback must be moved to the 'data' | |
1231 | descriptor when data transfer begins. Otherwise we are | |
1232 | likely to get a timeout on the control descriptor. | |
1233 | - Fixed double-free bug in httpRequestFree(). | |
1234 | - Fixed store_swap_size counting bug in storeSwapOutHandle(). | |
1235 | ||
409a6aad | 1236 | Changes to squid-1.2.beta3 (Oct 29, 1997): |
1237 | ||
1238 | - Initialize _res.options to RES_DEFAULT in dnsserver.c. | |
1239 | - Fix assertions which assumed 4-byte pointers. | |
1240 | - Fix missing % in fqdncache.c snprintf(). | |
1241 | ||
5a2d610b | 1242 | Changes to squid-1.2.beta2 (Oct 28, 1997): |
1243 | ||
8c3994aa | 1244 | - Fixed aiops.c and async_io.c so that they actually compile |
f5b8bbc4 | 1245 | with USE_ASYNC_IO (Arjan de Vet). |
1246 | - Fixed errState->errno causing problems with some macros | |
1247 | (Michael O'Reilly). | |
d287f51e | 1248 | - Fixed memory leaks in pconn.c (Max Okumoto). |
0866009b | 1249 | - Enhanced 'client' program with 'ping' behaviour (Ron Gomes). |
272547b5 | 1250 | - Fixed InvokeHandlers() from calling memCopy() for ALL |
1251 | store_client's with callbacks. A store_client might be reading | |
1252 | from disk. | |
5a2d610b | 1253 | - Rewrote storeMaintainSwapSpace(). No longer will we scan one |
272547b5 | 1254 | bucket at a time. Instead we'll maintain a single LRU |
1255 | list. When an object is 'touched' we move it to the | |
1256 | top of this list. When we need disk space, we delete | |
1257 | from the bottom. | |
5a2d610b | 1258 | - Removed storeGetSwapSpace(). |
f5b8bbc4 | 1259 | |
871f0b8a | 1260 | Changes to squid-1.2.beta1 (): |
1261 | ||
1262 | - Reworked storage manager to not keep objects in memory during | |
1263 | transit. In other words, no separate NOVM distribution. | |
1264 | - Lots of cleanup and debugging for beta release. | |
1265 | - Use snprintf() everywhere instead of sprintf(). | |
1266 | - The 'in_memory' hash table has been replaced with a | |
1267 | doubly-linked list. New objects are added to the head of | |
1268 | the list. When memory space is needed, old objects are | |
1269 | purged from the tail of the list. | |
1270 | ||
0edfe7a2 | 1271 | Changes to squid-1.2.alpha7 (): |
1272 | ||
c4958532 | 1273 | - fixes fixes fixes. |
1274 | - Made Arjan's PROXY_AUTH ACL patch standard. | |
0edfe7a2 | 1275 | |
8905b90c | 1276 | Changes to squid-1.2.alpha6 (): |
1277 | ||
6684fec0 | 1278 | - Simpler cacheobj implementation. |
6605655c | 1279 | - persistent connection histogram |
8872e1f8 | 1280 | - SERVER-SIDE PERSISTENT CONNECTIONS: |
1281 | - Added pconn.c | |
1282 | - Addec Cofig.Timeout.pconn; default 120 seconds | |
1283 | - Added httpState->flags | |
1284 | - Added flags arg to httpBuildRequestHeader() | |
1285 | - Added HTTP_PROXYING and HTTP_KEEPALIVE flags | |
1286 | - Added 'Connection' to allowed HTTP headers (http-anon.c) | |
1287 | - Added 'Proxy-Connection' to allowed HTTP headers | |
1288 | (http-anon.c) | |
a7736231 | 1289 | - Merged proxyhttpStart() with httpStart() and created |
8872e1f8 | 1290 | new httpBuildState(). |
1291 | - New httpPconnTransferDone() detects end-of-data on | |
1292 | persistent connections. | |
6684fec0 | 1293 | |
88738790 | 1294 | Changes to squid-1.2.alpha5 (): |
1295 | ||
1296 | - New configuration system. Everything is generated from | |
1297 | 'cf.data.pre', including the main parser, setting defaults, | |
1298 | outputting current values, and freeing memory. | |
1299 | This also involved moving some of the local data structures | |
1300 | (e.g. struct _acl *AclList in acl.c) to the Config | |
1301 | structure. (Max Okumoto) | |
1302 | - No more '/i' for regular expressions. Now insert a '-i' | |
1303 | to switch to case-insensitive. Use '+i' for case-sensitive. | |
1304 | - When you have a variable named the same as its type, sizeof() | |
1305 | gets the wrong one (fde). | |
1306 | - Need to flush unbuffered logs before fork(). | |
1307 | - Added two fields swap log: refcount and e->flag. | |
1308 | - Removed all the .h files for each .c file. Now #include stuff | |
1309 | is in either: defines.h, enums.h, typedefs.h, structs.h, | |
1310 | or protos.h, globals.h. This greatly reduces dependencies | |
1311 | between the various source files. | |
1312 | - globals.c is generated from globals.h by a Perl script. | |
8ee3ca2c | 1313 | - Started customizable error texts. |
88738790 | 1314 | |
97f674c8 | 1315 | Changes to squid-1.2.alpha4 (): |
1316 | ||
ec973719 | 1317 | - New MIME configuration, regular expression based |
1318 | - Added request_timeout config option | |
1319 | - Multiple HTTP sockets (Lincoln Dale). | |
1320 | - Moved 'fds_are_n_free' check to httpAccept(). | |
1321 | - s/USE_POLL/HAVE_POLL/; make poll() default if available. | |
7e49f700 | 1322 | - Changed storeRegister to use offsets and make immediate |
1323 | callbacks if appropriate. | |
1324 | - Removed icpDetectClientClose(). Some of that functionality | |
1325 | goes into clientReadRequest() and the rest into | |
1326 | httpRequestFree(). | |
b1b387d1 | 1327 | - Moved IP lookups to commConnect stuff. |
1328 | - Added support for retrying connect(). | |
858164fc | 1329 | - New inline debug() macro (David Luyer). |
e174e0fe | 1330 | - Replace frequent gettimeofday() calls with alarm(3) based |
1331 | clock. Need to add more gettimeofday() calls to get back | |
a59968c7 | 1332 | high-resolution timestamp logging (Andres Kroonmaa). |
0153d498 | 1333 | - Added support for Cache-control: proxy-revalidate; |
1334 | based on squid-1.1 patch from Mike Mitchell. | |
ec973719 | 1335 | |
3b08d32d | 1336 | Changes to squid-1.2.alpha3 (): |
1337 | ||
1338 | - Implemented persistent connections between clients and squid. | |
1339 | - Moved various FD tables (comm.c, fdstat.c, disk.c) to a single | |
1340 | table in fd.c. | |
1341 | - Removed use of FD as an identifier in certain callback | |
1342 | operations (ipcache, fqdncache). | |
1343 | - General code cleanup. | |
1344 | - Fixed typedefs for callback functions. | |
1345 | - Removed FD lifetime/timeout dichotomy. Now we only have | |
1346 | timeouts, however the lifetime concept/keyword may still | |
1347 | linger in certain places. | |
1348 | - Change Makefile 'realclean' target to 'distclean' | |
1349 | - Changed config file parsing of time specifications to use | |
1350 | parseTimeLine(). | |
1351 | - Removed storetoString.c | |
1352 | ||
1353 | Changes to squid-1.2.alpha2 (): | |

1356 | ||
7b41ec97 | 1357 | Changes to squid-1.2.alpha1 (): |
1358 | ||
1359 | - Unified peer selection algorithm. | |
75e88d56 | 1360 | - aiops.c and aiops.h are a threaded implementation of |
1361 | asynchronous file operations (Stewart Forster). | |
1362 | - async_io.c and async_io.h are complete rewrites of the old | |
1363 | versions (Stewart Forster). | |
6ad85e8a | 1364 | - Rewrote all disk file operations of squid to support |
75e88d56 | 1365 | the idea of callbacks except where not required (Stewart |
1366 | Forster). | |
75e88d56 | 1367 | - Background validation of 'tainted' swap log entries (Stewart |
1368 | Forster). | |
1369 | - Modified storeWriteCleanLog to create the log file using the | |
1370 | open/write rather than fopen/printf (Stewart Forster). | |
1371 | - Added the EINTR error response to handle badly interrupted | |
1372 | system calls (Stewart Forster). | |
6ad85e8a | 1373 | - UDP_HIT_OBJ not supported, removed. |
1374 | - Different sized 'cache_dirs' supported. | |
