5 * Added the SSL_CLIENT_SERVER_NAME CGI variable.
6
7 ** Changes from 0.1.5 to 0.1.6 - 24/07/2004
8 * Some changes to support the new PHP REQUEST_STATUS environment
9 variable.
10 * Some fixes for gnutls.
11
12 ** Changes from 0.1.4 to 0.1.5 - 03/04/2004

16 * Better large file support (now uses the included autoconf macros)
17 * Added dependency on gnutls 0.9.5
18
19 ** Changes from 0.1.2 to 0.1.3 - 20/01/2003
20 * Added DefaultCharset configuration directive. The default
21 character set given, will be appended to all text mime types.
22 * Corrected bug in KeepAlive usage in HTTP/1.1, which made the
23 server to ignore the value sent by the client.
24 * CGIAction can now be used even if HIC CGIs are disabled.
25 * Some optimizations in HTTP header parsing.
26 * Added a more complete mime.types in examples/ contributed by
27 <voidnull@qnet.pl>.
28 * Added the MaxSSLConnections configuration directive.
29 * Two mutexes are used in accept to allow parallel accepts
30 of SSL and plain connections.
31 * Added Dependency on gnutls 0.8.0.
32
33 ** Changes from 0.1.1 to 0.1.2 - 08/01/2003
34 * Allow running the server as root, if explicitly stated in
35 configuration file. Patch by James Harr <james@grickle.org>
36 * Better pthreads detection.
37 * Outputs to error log if non executable CGIs are found.
38 * Does not close HTTP/1.1 connections by default.
39 * The current behavour is to demand the Host header in HTTP/1.1
40 requests.
41 * Added support for CGIAction CGIs. There are just like CGIs
42 but they are not executed. They are parsed using a given program.
43 * Added init script for redhat in contrib/redhat/rc.hydra,
44 contributed by <voidnull@qnet.pl>.
45
46 ** Changes from 0.1.0 to 0.1.1 - 17/12/2002
47 * Corrected bug in Keep-Alive mode when SSL or TLS was enabled.
48 * Fixed unexpected timeout in first connection on an idle server.
49
50 ** Changes from 0.0.10 to 0.1.0 - 16/11/2002
51 * No changes. This is the final release by me --Nikos
52
53 ** Changes from 0.0.9 to 0.0.10 - 08/11/2002
54 * Corrected bug in error logging.
55 * Use the TMPDIR environment variable instead of TMP to get
56 the temporary directory.
57
58 ** Changes from 0.0.8 to 0.0.9 - 27/10/2002
59 * Long offsets are not used by default.
60 * Use of pipes instead of temporary files, if the post data sent
61 are less than PIPE_BUF.
62 * More consistent logging. The server's hostname or "unknown"
63 are prepended to the log message.
64 * Corrected redirection/aliases behaviour, to match the documented one.
65 * SSLParamsRefresh was renamed to MaintenanceInterval and is more
66 generic, since it includes some server cleanups.
67 * Added file access control lists per virtual host. Based on patch for
68 Boa by Peter Korsgaard <jacmet@sunsite.dk>
69 * Added the ability to disable HIC threads by using 0 in the
70 HICThreads configuration directive.
71 * Hydra now uses poll by default. Select is available using the --with-select
72 configure option.
73
74 ** Changes from 0.0.7 to 0.0.8 - 25/10/2002
75 * Better pthread detection.
76 * Better detection of dlopen call.
77 * Some changes to compile in gcc 2.95
78 * Added support for FreeBSD's sendfile (untested).
79 [Ported from Boa 0.94.14rc1]
80 * add new state, IOSHUFFLE, which utilizes sendfile (or
81 emulates it using the request's buffer, otherwise)
82 * make the default socket size 32K. The client_stream_size stays constant
83 at 8K, and the new 'buffer' size is 4K
84 Note also that the new code uses the "default" socket buffer size
85 it obtains with the first accept()ed socket.
86 * make default behavior be to leave stderr alone, but tie it
87 to cgilog otherwise
88 * add [optional, Linux-only] check for sendfile system call
89 * use --disable-sendfile to disable sendfile support
90 sendfile support for files > 100K is default, now.
91 It's significantly faster and easier than the alternative
92 * umask ~0770 before exec
93 * tie stdout to the access_log, unless there is no access_log,
94 in which case tie it to /dev/null
95 * use sensible defaults for umask (077) and (027 for CGI)
96 * add and document new parameters (CGILog and CGIumask)
97 * vast improvements to the cgi-test.cgi program, by Jon Nelson
98 and Landon Curt Noll.
99 * next 3 items by Don Mahurin (patches modified somewhat):
100 * pidfile patch
101 * default mime_types patch
102 * NCSA environment environment variables wrapped in
103 #ifdef USE_NCSA_CGI_ENV
104 * fix some escaping issues with the directory indexer
105 (Ulf Harnhammar)
106 * backport poll support from 0.95
107
108 ** Changes from 0.0.6 to 0.0.7 - 10/10/2002
109 * Added support for large files in 32 bit systems.
110 * Added support for SSL_* variables in CGIs.
111 * Added options in configuration file, to request and verify
112 a client certificate.
113 * The headers of HIC-CGIs are now parsed by the server.
114 * Corrected behavour in SIGHUP signal handling, to reread
115 the SSL related variables.
116 * Children and HIC threads are now killed using a signal, to avoid
117 unexpected errors, and memory leaks.
118
119 ** Changes from 0.0.5 to 0.0.6 - 03/10/2002
120 * Compatibility functions are now automatically included in hydra, if
121 they are not found by the configure script.
122 * Replaced the included scandir function, with the one in libc.
123 * Fixed code, which compiled fine with gcc 3.2, but didn't compile at
124 all, with any other compiler!
125 * Improved the MaxConnections directive semantics.
126 * Added a very primitive mime.types file in examples/ directory.
127
128 ** Changes from 0.0.4 to 0.0.5 - 02/10/2002
129 * If a requested CGI is not accesible then send 404 not found, instead
130 of trying to execute it.
131 * Corrected several stuff in HIC CGI handler. This allows Cookies,
132 POST data and Queries to work properly.
133
134 ** Changes from 0.0.3 to 0.0.4 - 30/09/2002
135 * Added support for If-Range, If-Match, If-None-Match HTTP/1.1 header
136 fields. The server also generates ETag headers for static content using
137 the last modified field of the file, and the file size. This makes
138 Hydra cache friendly.
139 * Added support for multiple HIC threads. This gives a boost to script generation
140 since they are no longer generated sequentially.
141
142 ** Changes from 0.0.2 to 0.0.3 - 28/09/2002
143 * Added support for dynamic modules that handle CGIs
144 internally (HIC). That way Hydra can run PHP.
145 * Fixes in CGI execution. CGIs that are not passed from aliasing
146 functions now properly set PATH_INFO and PATH_TRANSLATED.
147 (Needs further cleanup).
148 * Cleaned up SSL support. Now hydra can be compiled even if gnutls
149 is not available.
150
151 ** Changes from Boa/0.94.13 to Hydra/0.0.2 - 26/09/2002
152 * Added support for SSL 3.0 and TLS 1.0 protocols.
153 * Added support for multiple CPU's by making the server
154 run over a pool of threads.
155 * Changed the file caching code. The mmap() calls are cached until
156 the mmap list table is full.
157 * Added support for HTTP/1.1 ranges.
158 * Added support for hostname based virtual hosting.
159 Also changed the semantics of Alias, ScriptAlias and Redirect, to
160 take advantage of the host based virtual hosting.
161 * Added support for the TCP_CORK tcp option in linux.
162 * Cleaned up the CGI handling (gunzip, indexer are treated as CGIs)
163 * Enhanced grammar to handle 3 and 4 argument options.
164 * Added support for multiple directory indexes.
165 * Dropped support for gunzip.
166 * Use automake to create the distribution.
167
168 ** Changes from 0.94.12 to 0.94.13
169 * Change many instances of log_error_mesg + exit to DIE macro
170 * Change all instance of log_error_mesg (without exit) to WARN macro
171 * do a much better job of checking return values from malloc and
172 especially strdup.
173 * check results of calling umask and getrlimit
174 * server_s is no longer a global int
175 * check results of fork via switch instead of if (fork())
176 * check for getopt.h and include it if found
177 * remove unused #defines, and add WARN macro, and replace
178 many calls to log_error_mesg(..) with WARN macro
179 * fix bug in get_commonlog_time where time_offset calculation was
180 the opposite of what it should be ('-' and '+' were swapped)
181 * fix compatability bug with old and newer versions of flex/yacc
182 * add check for AC_FUNC_MMAP to configure.in
183 * fix really lame thinko in normalize_path, which would prepend the
184 results of earlier calls to results from later calls
185 * Add MaxConnections, a configuration directive which allows the
186 user to specify the maximum number of connections that Boa will
187 accept concurrently.
188 * add SERVER_ADDR and REQUEST_URI to environment of CGI
189 * handle SIGBUS during writes of data that has been memory mapped
190 * minor optimization in select.c that prevents DEAD requests from
191 being added to the block set
192 * fix bug in CGI environment script_name - closes sf.net bug #576725
193 * make 'status' variable local to requests.c, not local to every file
194 by forgetting to declare 'extern' in globals.h :-|
195 * make getsockname non-fatal, and do it every time because we may
196 need it for the CGI
197 * some minor refactoring optimizations in hash.c
198
199 ** Changes from 0.94.11 to 0.94.12
200 * Renamed Changelog ChangeLog, and moved up to top-level directory
201 * Next 3 items due in part or whole thanks to
202 Liam Widdowson
203 * when printf'ing a pid type, force to int, because it could be
204 something else on other platforms. Should probably change it to
205 a long, and use that.
206 * backported chroot commandline support from 0.95
207 * backported support for strdup, strstr, alphasort, and scandir
208 from 0.95
209 * Fixed src/Makefile.in -- it didn't remove index_dir.o
210 * backport create_temporary_file from 0.95
211 (instead of using tmpnam)
212 * Allow non-standard date format 31 September 2000 23:59:59 GMT
213 Patch by Landon Curt Noll
214 * Skip whitespace before HTTP/major.minor
215 Adapted patch from Landon Curt Noll
216 * open /dev/null first thing (affects chrooting)
217 * properly handle sigalrm -- use sigalrm_flag and sigalrm_run
218 instead of handling the signal in the signal handler
219 * update manpage slightly
220 * send 400 BAD Request when resource does not start with '/'
221 * add grp.h to boa.h's includes -- remove from boa.c and config.c
222 * removed duplicate header includes from boa.c, config.c, get.c,
223 ip.c, request.c, response.c
224 * factor out creating the server socket and dropping privs
225 into create_server_socket and drop_privs
226 * type all functions in boa.c (except main) as static
227 * set umask after opening /dev/null
228 * tie stdin/stdout to /dev/null before commandline parse
229 * removed old, unused chroot code
230 * move builds_needs_escape earlier in the startup
231 * move fork later in the startup
232 * type all c_set_* as static in config.c
233 * don't bother trying to change uid/gid (or error if the
234 requested uid/gid doesn't exist) if not UID 0
235 * return more appropriate error code when foo.html gives
236 access denied, but foo.html.gz gives some other error
237 (essentially report error associated with foo.html, not foo.html.gz)
238 * send NOT Implemented when an unknown method is attempted
239 * always attempt a 32k read right before close
240 (stopgap until blackhole can be merged)
241 * allow more than 1 space in logline between method, resource,
242 and http version
243 * don't use inline functions
244 * update configure.in so that autoconf 2.50 doesn't complain (as much)
245 * properly use VPATH and srcdir according to autoconf docs
246 * change curly-braces to parentheses in Makefilein
247 * use $^ instead of manually listing the dependencies in Makefile.in
248 * remove tests section in Makefile.in
249 * write tags not TAGS in Makefile.in
250 * Add gethostbyname and inet_aton to function checks
251 * Add code from 0.95 which checks for socket in -lsocket,
252 inet_aton in -lresolv, and gethost{by}name in -lnsl
253 * Also remove broken bc-based "how big is an unsigned int" checks:
254 assume minimum of 32 bits and check in escape.c at runtime.
255 * Added new file: README.chroot.solaris, based on a
256 modified version by Liam Widdowson
257 * Add check_struct_for.m4, which allows us to check a structure
258 for a member (found at http://www.gnu.org/software/ac-archive/
259 authored by Wes Hardaker
260 * Call "aclocal -I ." to rebuild aclocal.m4
261 * Using new check-struct-for-member autoconf macro, check
262 for tm_gmtoff and tm_zone in struct tm -- useful in
263 portability tests for localtime.
264 * Also check sockaddr_in for structure sin_len so we can set
265 it properly.
266 * index_dir.c (which ends up in boa_indexer) can now be compiled
267 with USE_LOCALTIME, and if so, it will report the local time
268 using the timezone name. Otherwise it uses UTC time and UTC
269 timezone designation.
270 * fix buglet in mmap_cache.c which shows up when under
271 heavy load by many different files.
272 Found and squashed by Michal Kara
273 * normalize paths on Aliases, log files, server root, dirmaker
274 This makes sure that paths are 'absolute'
275 * don't generate DOCUMENT_ROOT or SERVER_ROOT,
276 CGIs have no business knowing that information
277 * if CGI, chdir to the cgi's root path
278 Bug found by Matt Callaway
279 * remove ChrootPath and PidFile directives from the parser
280 (they aren't used anyway)
281 * keep track of maximum file descriptor in use to optimize call
282 to select()
283 * apply IPv6 patch from Jari Korva
284 * optimize keep-alive copy data routine
285 * try to use memcpy instead of strcpy/strcat in more places (alias.c)
286 * update .depend file
287 * use fcntl + GET_FL to get a file descriptor's flags, then
288 add or remove only the bits we want to set. This prevents
289 accidentally setting or unsettings bits we don't have anything
290 to do with inadvertantly. (removed, at least temporarily.
291 Show me a system where it is needed -- LRD)
292 * make sure to call FD_ZERO when we handle a restart
293 * in read.c, don't call boa_perror on read failure -- socket is
294 dead or messed up anyway, no reason to try to write to it.
295 * explicit .SUFFIXES in Makefile.in
296 * boa.objdump target added
297 * use @MAKE_SET@ (for when $(MAKE) != "make")
298 * add -Wundef -Wwrite-strings -Wredundant-decls -Winline to GCC_FLAGS
299 * change Paul Phillips' and Larry Doolittle's emails in source
300 * add --disable-debug, --enable-profile, --with-dmalloc, and --with-efence
301 * test for failed-but-return-was-successful setuid:
302 http://www.securityfocus.com/bid/1322
303 * use _exit not exit in CGI child
304 * always place new keepalive request on blocked list, we can't be
305 sure of the state of the active list, and since enqueue places
306 things at the *front* of the list, it doesn't do us much good
307 to place the new request on the active list anyway.
308 * update some Copyright statements for 2002
309 * When comparing the uri to an alias, only compare if
310 the uri length is greater than or equal to the length of the alias
311 * in init_script_alias, make sure to check for document_root before
312 trying to use it
313 * script_name is now just a copy of the request, rather
314 than some complicated variation on the pathname
315 * change the way the CGI environment is handled.
316 Now, it is allocated at request allocation time, and exists
317 throughout the life of the structure.
318 * check memory allocations, etc.. when creating the static
319 CGI environment and when making new CGI environment variables
320 * wait until process_option_end to call unescape_uri, clean_pathname,
321 and translate_uri
322 * remove debian package information
323 * move RedHat packaging information to contrib
324 * remove tests -- they weren't usable anyway
325 * add some new hash routines, and use djb2 (a variant on a
326 hash algorithm popularized by Dan J. Bernstein)
327 * a side-effect of the new hash routines is a bugfix,
328 involving negative return values from hash routines.
329 This has been fixed.
330 * add a routine, show_hash_stats, which is called with other
331 statistical output via sigalarm
332 * remove some duplicate prototypes from config.c
333 * make simple_itoa take an unsigned int
334 * try to make NOBLOCK handling in compat.h compatible with Solaris
335 * make sure to update current_time before calling signal handlers
336 * alter primary loop to make sure that select gets called even
337 when there are requests that are not blocking, and call fdset_update
338 and process_requests (when appropriate) after signal handlers but
339 before select to make sure that blocked requests are still handled
340 by select after a sighup. (Thanks to Karl Olsen)
341 * pull select loop into select.c
342 * poll server socket once per active connection
343 * add send_r_service_unavailable and use it when appropriate
344 * state uptime in seconds at normal program termination
345 * include sys/fcntl.h if it is found by configure
346 * fix POST bug where a content-length < 0 would cause Boa to
347 consume its full share of CPU until killed
348 Bug report by Landon Curt Noll
349 * add CGIPath configuration variable
350 based upon a patch by Landon Curt Noll
351 * add function boa_atoi, which wraps atoi, but does not
352 accept negative values. Additionally, it checks to make sure
353 the converted value and the original value are the same, avoiding
354 issues like "124.3" -> "123" and "123abc" -=> "123".
355 Either a value is an int or it isn't - no middle ground.
356 * use boa_atoi to convert content-length from client.
357 * add new #define - SINGLE_POST_LIMIT_DEFAULT, which defines
358 (in bytes) the *default* single_post_limit.
359 * single_post_limit is now in bytes.
360 * when adding aliases, only "normalize" paths that start
361 with "./" - this is a departure from previous behavior
362 * add "?" to the list of characters that it is safe to leave unescaped
363 * clean up Makefile.in of no-longer-pertinent comments
364 * add send_r_bad_gateway and use it
365 * tie stderr to either cgi_log_fd or devnullfd - either way
366 make sure stderr is a valid filehandle before cgi execution
367 * cgi_env is no longer allocated, it's part of the struct now
368 * fix bug in CgiPath logic
369 * when unable to allocate memory for an environment variable, log it
370 * add clear_common_env, which de-allocates the cgi_common_env stuff
371 [NEVER USE THIS outside of a terminal signal handler!]
372 * don't be so wasteful of memory in normalize_path
373 * adapted fix for alias expansion from Brieuc Jeunhomme
374
375 ** Changes from 0.94.10.1 to 0.94.11
376 * use LIBS in Makefile.in (which propagates from autoconf)
377 * properly free memory allocated by scandir in index_dir.c
378 * rearrange some header files and includes
379 * on reads and writes, don't check for -1, check for < 0
380 * include fix by William Meadows
381 for escape.c which fixes segfaults due to improper allocation
382 * above fix by William Meadows no longer needed;
383 escape.c and escape.h rewritten by Larry Doolittle -- requires
384 at least 32 bit words, but is correct (jdn's 1st attempt was faulty)
385
386 ** Changes from 0.94.10 to 0.94.10.1
387 * Actually update the SERVER_VERSION in src/defines.h

394 * Update documentation regarding mime.types (Closes Debian #69991)
395 * Make sure documentation builds (Closes Debian #110818)
396
397 ** Changes from 0.94.8.3 to 0.94.9
398 * src/Makefile.in updated to take CFLAGS, LIBS, and LDFLAGS
399 from autoconf
400 * Update escaping rules with latest RFC
401 * unescape_uri skips fragments and also stop parsing at '?'
402 * Don't accept fd over FD_SETSIZE in request.c:get_request
403 * use backported documentation from 0.95
404 * make sure POST fd gets closed even on client cancel
405 * use backported index_dir.c from 0.95
406 * support subdirectories in ScriptAlias directories
407 * add SinglePostLimit (int, in Kilobytes) to config system
408 * check for ENOSPC on body write
409 * use environment variable TMP (or "/tmp" if not available),
410 and chdir there when boa exits.
411 * add 1-time-only hack to make a 32kB read at the end of a request
412 on POST or PUT
413 * close unused file descriptors (/dev/null in boa.c, and the
414 unused part of the pipes call in cgi.c)
415 * made Makefile.in VPATH happy
416
417 ** Changes from 0.94.8.2 to 0.94.8.3

432 * Fix major thinko in temp file permissions
433 * unlink temporary file immediately following creation
434 * implement maximum # of active connections at 10 less than RLIMIT_NOFILE
435 to avoid or eliminate crashes resulting from running out of
436 file descriptors
