Branch: MAIN
CVS Tags: hydra_0_0_9
Changes since 1.45: +5 -1 lines
Added the ability to disable HIC threads by using 0 in the
HICThreads configuration directive.
Hydra now uses poll by default. Select is available using the --with-select
configure option.

1 ** Changes from 0.0.8 to 0.0.9 - 27/10/2002
2 * Long offsets are not used by default.
3 * Use of pipes instead of temporary files, if the post data sent
4 are less than PIPE_BUF.
5 * More consistent logging. The server's hostname or "unknown"
6 are prepended to the log message.
7 * Corrected redirection/aliases behaviour, to match the documented one.
8 * SSLParamsRefresh was renamed to MaintenanceInterval and is more
9 generic, since it includes some server cleanups.
10 * Added file access control lists per virtual host. Based on patch for
11 Boa by Peter Korsgaard <jacmet@sunsite.dk>
12 * Added the ability to disable HIC threads by using 0 in the
13 HICThreads configuration directive.
14 * Hydra now uses poll by default. Select is available using the --with-select
15 configure option.
16
17 ** Changes from 0.0.7 to 0.0.8 - 25/10/2002
18 * Better pthread detection.
19 * Better detection of dlopen call.
20 * Some changes to compile in gcc 2.95
21 * Added support for FreeBSD's sendfile (untested).
22 [Ported from Boa 0.94.14rc1]
23 * add new state, IOSHUFFLE, which utilizes sendfile (or
24 emulates it using the request's buffer, otherwise)
25 * make the default socket size 32K. The client_stream_size stays constant
26 at 8K, and the new 'buffer' size is 4K
27 Note also that the new code uses the "default" socket buffer size
28 it obtains with the first accept()ed socket.
29 * make default behavior be to leave stderr alone, but tie it
30 to cgilog otherwise
31 * add [optional, Linux-only] check for sendfile system call
32 * use --disable-sendfile to disable sendfile support
33 sendfile support for files > 100K is default, now.
34 It's significantly faster and easier than the alternative
35 * umask ~0770 before exec
36 * tie stdout to the access_log, unless there is no access_log,
37 in which case tie it to /dev/null
38 * use sensible defaults for umask (077) and (027 for CGI)
39 * add and document new parameters (CGILog and CGIumask)
40 * vast improvements to the cgi-test.cgi program, by Jon Nelson
41 and Landon Curt Noll.
42 * next 3 items by Don Mahurin (patches modified somewhat):
43 * pidfile patch
44 * default mime_types patch
45 * NCSA environment environment variables wrapped in
46 #ifdef USE_NCSA_CGI_ENV
47 * fix some escaping issues with the directory indexer
48 (Ulf Harnhammar)
49 * backport poll support from 0.95
50
51 ** Changes from 0.0.6 to 0.0.7 - 10/10/2002
52 * Added support for large files in 32 bit systems.
53 * Added support for SSL_* variables in CGIs.
54 * Added options in configuration file, to request and verify
55 a client certificate.
56 * The headers of HIC-CGIs are now parsed by the server.
57 * Corrected behavour in SIGHUP signal handling, to reread
58 the SSL related variables.
59 * Children and HIC threads are now killed using a signal, to avoid
60 unexpected errors, and memory leaks.
61
62 ** Changes from 0.0.5 to 0.0.6 - 03/10/2002
63 * Compatibility functions are now automatically included in hydra, if
64 they are not found by the configure script.
65 * Replaced the included scandir function, with the one in libc.
66 * Fixed code, which compiled fine with gcc 3.2, but didn't compile at
67 all, with any other compiler!
68 * Improved the MaxConnections directive semantics.
69 * Added a very primitive mime.types file in examples/ directory.
70
71 ** Changes from 0.0.4 to 0.0.5 - 02/10/2002
72 * If a requested CGI is not accesible then send 404 not found, instead
73 of trying to execute it.
74 * Corrected several stuff in HIC CGI handler. This allows Cookies,
75 POST data and Queries to work properly.
76
77 ** Changes from 0.0.3 to 0.0.4 - 30/09/2002
78 * Added support for If-Range, If-Match, If-None-Match HTTP/1.1 header
79 fields. The server also generates ETag headers for static content using
80 the last modified field of the file, and the file size. This makes
81 Hydra cache friendly.
82 * Added support for multiple HIC threads. This gives a boost to script generation
83 since they are no longer generated sequentially.
84
85 ** Changes from 0.0.2 to 0.0.3 - 28/09/2002
86 * Added support for dynamic modules that handle CGIs
87 internally (HIC). That way Hydra can run PHP.
88 * Fixes in CGI execution. CGIs that are not passed from aliasing
89 functions now properly set PATH_INFO and PATH_TRANSLATED.
90 (Needs further cleanup).
91 * Cleaned up SSL support. Now hydra can be compiled even if gnutls
92 is not available.
93
94 ** Changes from Boa/0.94.13 to Hydra/0.0.2 - 26/09/2002
95 * Added support for SSL 3.0 and TLS 1.0 protocols.
96 * Added support for multiple CPU's by making the server
97 run over a pool of threads.
98 * Changed the file caching code. The mmap() calls are cached until
99 the mmap list table is full.
100 * Added support for HTTP/1.1 ranges.
101 * Added support for hostname based virtual hosting.
102 Also changed the semantics of Alias, ScriptAlias and Redirect, to
103 take advantage of the host based virtual hosting.
104 * Added support for the TCP_CORK tcp option in linux.
105 * Cleaned up the CGI handling (gunzip, indexer are treated as CGIs)
106 * Enhanced grammar to handle 3 and 4 argument options.
107 * Added support for multiple directory indexes.
108 * Dropped support for gunzip.
109 * Use automake to create the distribution.
110
111 ** Changes from 0.94.12 to 0.94.13
112 * Change many instances of log_error_mesg + exit to DIE macro
113 * Change all instance of log_error_mesg (without exit) to WARN macro
114 * do a much better job of checking return values from malloc and
115 especially strdup.
116 * check results of calling umask and getrlimit
117 * server_s is no longer a global int
118 * check results of fork via switch instead of if (fork())
119 * check for getopt.h and include it if found
120 * remove unused #defines, and add WARN macro, and replace
121 many calls to log_error_mesg(..) with WARN macro
122 * fix bug in get_commonlog_time where time_offset calculation was
123 the opposite of what it should be ('-' and '+' were swapped)
124 * fix compatability bug with old and newer versions of flex/yacc
125 * add check for AC_FUNC_MMAP to configure.in
126 * fix really lame thinko in normalize_path, which would prepend the
127 results of earlier calls to results from later calls
128 * Add MaxConnections, a configuration directive which allows the
129 user to specify the maximum number of connections that Boa will
130 accept concurrently.
131 * add SERVER_ADDR and REQUEST_URI to environment of CGI
132 * handle SIGBUS during writes of data that has been memory mapped
133 * minor optimization in select.c that prevents DEAD requests from
134 being added to the block set
135 * fix bug in CGI environment script_name - closes sf.net bug #576725
136 * make 'status' variable local to requests.c, not local to every file
137 by forgetting to declare 'extern' in globals.h :-|
138 * make getsockname non-fatal, and do it every time because we may
139 need it for the CGI
140 * some minor refactoring optimizations in hash.c
141
142 ** Changes from 0.94.11 to 0.94.12
143 * Renamed Changelog ChangeLog, and moved up to top-level directory
144 * Next 3 items due in part or whole thanks to
145 Liam Widdowson
146 * when printf'ing a pid type, force to int, because it could be
147 something else on other platforms. Should probably change it to
148 a long, and use that.
149 * backported chroot commandline support from 0.95
150 * backported support for strdup, strstr, alphasort, and scandir
151 from 0.95
152 * Fixed src/Makefile.in -- it didn't remove index_dir.o
153 * backport create_temporary_file from 0.95
154 (instead of using tmpnam)
155 * Allow non-standard date format 31 September 2000 23:59:59 GMT
156 Patch by Landon Curt Noll
157 * Skip whitespace before HTTP/major.minor
158 Adapted patch from Landon Curt Noll
159 * open /dev/null first thing (affects chrooting)
160 * properly handle sigalrm -- use sigalrm_flag and sigalrm_run
161 instead of handling the signal in the signal handler
162 * update manpage slightly
163 * send 400 BAD Request when resource does not start with '/'
164 * add grp.h to boa.h's includes -- remove from boa.c and config.c
165 * removed duplicate header includes from boa.c, config.c, get.c,
166 ip.c, request.c, response.c
167 * factor out creating the server socket and dropping privs
168 into create_server_socket and drop_privs
169 * type all functions in boa.c (except main) as static
170 * set umask after opening /dev/null
171 * tie stdin/stdout to /dev/null before commandline parse
172 * removed old, unused chroot code
173 * move builds_needs_escape earlier in the startup
174 * move fork later in the startup
175 * type all c_set_* as static in config.c
176 * don't bother trying to change uid/gid (or error if the
177 requested uid/gid doesn't exist) if not UID 0
178 * return more appropriate error code when foo.html gives
179 access denied, but foo.html.gz gives some other error
180 (essentially report error associated with foo.html, not foo.html.gz)
181 * send NOT Implemented when an unknown method is attempted
182 * always attempt a 32k read right before close
183 (stopgap until blackhole can be merged)
184 * allow more than 1 space in logline between method, resource,
185 and http version
186 * don't use inline functions
187 * update configure.in so that autoconf 2.50 doesn't complain (as much)
188 * properly use VPATH and srcdir according to autoconf docs
189 * change curly-braces to parentheses in Makefilein
190 * use $^ instead of manually listing the dependencies in Makefile.in
191 * remove tests section in Makefile.in
192 * write tags not TAGS in Makefile.in
193 * Add gethostbyname and inet_aton to function checks
194 * Add code from 0.95 which checks for socket in -lsocket,
195 inet_aton in -lresolv, and gethost{by}name in -lnsl
196 * Also remove broken bc-based "how big is an unsigned int" checks:
197 assume minimum of 32 bits and check in escape.c at runtime.
198 * Added new file: README.chroot.solaris, based on a
199 modified version by Liam Widdowson
200 * Add check_struct_for.m4, which allows us to check a structure
201 for a member (found at http://www.gnu.org/software/ac-archive/
202 authored by Wes Hardaker
203 * Call "aclocal -I ." to rebuild aclocal.m4
204 * Using new check-struct-for-member autoconf macro, check
205 for tm_gmtoff and tm_zone in struct tm -- useful in
206 portability tests for localtime.
207 * Also check sockaddr_in for structure sin_len so we can set
208 it properly.
209 * index_dir.c (which ends up in boa_indexer) can now be compiled
210 with USE_LOCALTIME, and if so, it will report the local time
211 using the timezone name. Otherwise it uses UTC time and UTC
212 timezone designation.
213 * fix buglet in mmap_cache.c which shows up when under
214 heavy load by many different files.
215 Found and squashed by Michal Kara
216 * normalize paths on Aliases, log files, server root, dirmaker
217 This makes sure that paths are 'absolute'
218 * don't generate DOCUMENT_ROOT or SERVER_ROOT,
219 CGIs have no business knowing that information
220 * if CGI, chdir to the cgi's root path
221 Bug found by Matt Callaway
222 * remove ChrootPath and PidFile directives from the parser
223 (they aren't used anyway)
224 * keep track of maximum file descriptor in use to optimize call
225 to select()
226 * apply IPv6 patch from Jari Korva
227 * optimize keep-alive copy data routine
228 * try to use memcpy instead of strcpy/strcat in more places (alias.c)
229 * update .depend file
230 * use fcntl + GET_FL to get a file descriptor's flags, then
231 add or remove only the bits we want to set. This prevents
232 accidentally setting or unsettings bits we don't have anything
233 to do with inadvertantly. (removed, at least temporarily.
234 Show me a system where it is needed -- LRD)
235 * make sure to call FD_ZERO when we handle a restart
236 * in read.c, don't call boa_perror on read failure -- socket is
237 dead or messed up anyway, no reason to try to write to it.
238 * explicit .SUFFIXES in Makefile.in
239 * boa.objdump target added
240 * use @MAKE_SET@ (for when $(MAKE) != "make")
241 * add -Wundef -Wwrite-strings -Wredundant-decls -Winline to GCC_FLAGS
242 * change Paul Phillips' and Larry Doolittle's emails in source
243 * add --disable-debug, --enable-profile, --with-dmalloc, and --with-efence
244 * test for failed-but-return-was-successful setuid:
245 http://www.securityfocus.com/bid/1322
246 * use _exit not exit in CGI child
247 * always place new keepalive request on blocked list, we can't be
248 sure of the state of the active list, and since enqueue places
249 things at the *front* of the list, it doesn't do us much good
250 to place the new request on the active list anyway.
251 * update some Copyright statements for 2002
252 * When comparing the uri to an alias, only compare if
253 the uri length is greater than or equal to the length of the alias
254 * in init_script_alias, make sure to check for document_root before
255 trying to use it
256 * script_name is now just a copy of the request, rather
257 than some complicated variation on the pathname
258 * change the way the CGI environment is handled.
259 Now, it is allocated at request allocation time, and exists
260 throughout the life of the structure.
261 * check memory allocations, etc.. when creating the static
262 CGI environment and when making new CGI environment variables
263 * wait until process_option_end to call unescape_uri, clean_pathname,
264 and translate_uri
265 * remove debian package information
266 * move RedHat packaging information to contrib
267 * remove tests -- they weren't usable anyway
268 * add some new hash routines, and use djb2 (a variant on a
269 hash algorithm popularized by Dan J. Bernstein)
270 * a side-effect of the new hash routines is a bugfix,
271 involving negative return values from hash routines.
272 This has been fixed.
273 * add a routine, show_hash_stats, which is called with other
274 statistical output via sigalarm
275 * remove some duplicate prototypes from config.c
276 * make simple_itoa take an unsigned int
277 * try to make NOBLOCK handling in compat.h compatible with Solaris
278 * make sure to update current_time before calling signal handlers
279 * alter primary loop to make sure that select gets called even
280 when there are requests that are not blocking, and call fdset_update
281 and process_requests (when appropriate) after signal handlers but
282 before select to make sure that blocked requests are still handled
283 by select after a sighup. (Thanks to Karl Olsen)
284 * pull select loop into select.c
285 * poll server socket once per active connection
286 * add send_r_service_unavailable and use it when appropriate
287 * state uptime in seconds at normal program termination
288 * include sys/fcntl.h if it is found by configure
289 * fix POST bug where a content-length < 0 would cause Boa to
290 consume its full share of CPU until killed
291 Bug report by Landon Curt Noll
292 * add CGIPath configuration variable
293 based upon a patch by Landon Curt Noll
294 * add function boa_atoi, which wraps atoi, but does not
295 accept negative values. Additionally, it checks to make sure
296 the converted value and the original value are the same, avoiding
297 issues like "124.3" -> "123" and "123abc" -=> "123".
298 Either a value is an int or it isn't - no middle ground.
299 * use boa_atoi to convert content-length from client.
300 * add new #define - SINGLE_POST_LIMIT_DEFAULT, which defines
301 (in bytes) the *default* single_post_limit.
302 * single_post_limit is now in bytes.
303 * when adding aliases, only "normalize" paths that start
304 with "./" - this is a departure from previous behavior
305 * add "?" to the list of characters that it is safe to leave unescaped
306 * clean up Makefile.in of no-longer-pertinent comments
307 * add send_r_bad_gateway and use it
308 * tie stderr to either cgi_log_fd or devnullfd - either way
309 make sure stderr is a valid filehandle before cgi execution
310 * cgi_env is no longer allocated, it's part of the struct now
311 * fix bug in CgiPath logic
312 * when unable to allocate memory for an environment variable, log it
313 * add clear_common_env, which de-allocates the cgi_common_env stuff
314 [NEVER USE THIS outside of a terminal signal handler!]
315 * don't be so wasteful of memory in normalize_path
316 * adapted fix for alias expansion from Brieuc Jeunhomme
317
318 ** Changes from 0.94.10.1 to 0.94.11
319 * use LIBS in Makefile.in (which propagates from autoconf)
320 * properly free memory allocated by scandir in index_dir.c
321 * rearrange some header files and includes
322 * on reads and writes, don't check for -1, check for < 0
323 * include fix by William Meadows
324 for escape.c which fixes segfaults due to improper allocation
325 * above fix by William Meadows no longer needed;
326 escape.c and escape.h rewritten by Larry Doolittle -- requires
327 at least 32 bit words, but is correct (jdn's 1st attempt was faulty)
328
329 ** Changes from 0.94.10 to 0.94.10.1
330 * Actually update the SERVER_VERSION in src/defines.h
331

341 * src/Makefile.in updated to take CFLAGS, LIBS, and LDFLAGS
342 from autoconf

350 * add SinglePostLimit (int, in Kilobytes) to config system
351 * check for ENOSPC on body write
352 * use environment variable TMP (or "/tmp" if not available),
353 and chdir there when boa exits.
354 * add 1-time-only hack to make a 32kB read at the end of a request
355 on POST or PUT
356 * close unused file descriptors (/dev/null in boa.c, and the
357 unused part of the pipes call in cgi.c)
358 * made Makefile.in VPATH happy
359
360 ** Changes from 0.94.8.2 to 0.94.8.3
