7
8 ** Changes from 0.1.5 to 0.1.6 - 24/07/2004
9 * Some changes to support the new PHP REQUEST_STATUS environment

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

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

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