Branch: hydra_0_1_0_patches
Changes since 1.49.2.14: +1 -0 lines
CGIAction can now be used even if HIC CGIs are disabled.

1 ** Changes from 0.1.2 to 0.1.3 -
2 * Added DefaultCharset configuration directive. The default
3 character set given, will be appended to all text mime types.
4 * Corrected bug in KeepAlive usage in HTTP/1.1, which made the
5 server to ignore the value sent by the client.
6 * CGIAction can now be used even if HIC CGIs are disabled.
7
8 ** Changes from 0.1.1 to 0.1.2 - 08/01/2003
9 * Allow running the server as root, if explicitly stated in
10 configuration file. Patch by James Harr <james@grickle.org>
11 * Better pthreads detection.
12 * Outputs to error log if non executable CGIs are found.
13 * Does not close HTTP/1.1 connections by default.
14 * The current behavour is to demand the Host header in HTTP/1.1
15 requests.
16 * Added support for CGIAction CGIs. There are just like CGIs
17 but they are not executed. They are parsed using a given program.
18 * Added init script for redhat in contrib/redhat/rc.hydra,
19 contributed by <voidnull@qnet.pl>.
20
21 ** Changes from 0.1.0 to 0.1.1 - 17/12/2002
22 * Corrected bug in Keep-Alive mode when SSL or TLS was enabled.
23 * Fixed unexpected timeout in first connection on an idle server.
24
25 ** Changes from 0.0.10 to 0.1.0 - 16/11/2002
26 * No changes. This is the final release by me --Nikos
27
28 ** Changes from 0.0.9 to 0.0.10 - 08/11/2002
29 * Corrected bug in error logging.
30 * Use the TMPDIR environment variable instead of TMP to get
31 the temporary directory.
32
33 ** Changes from 0.0.8 to 0.0.9 - 27/10/2002
34 * Long offsets are not used by default.
35 * Use of pipes instead of temporary files, if the post data sent
36 are less than PIPE_BUF.
37 * More consistent logging. The server's hostname or "unknown"
38 are prepended to the log message.
39 * Corrected redirection/aliases behaviour, to match the documented one.
40 * SSLParamsRefresh was renamed to MaintenanceInterval and is more
41 generic, since it includes some server cleanups.
42 * Added file access control lists per virtual host. Based on patch for
43 Boa by Peter Korsgaard <jacmet@sunsite.dk>
44 * Added the ability to disable HIC threads by using 0 in the
45 HICThreads configuration directive.
46 * Hydra now uses poll by default. Select is available using the --with-select
47 configure option.
48
49 ** Changes from 0.0.7 to 0.0.8 - 25/10/2002
50 * Better pthread detection.
51 * Better detection of dlopen call.
52 * Some changes to compile in gcc 2.95
53 * Added support for FreeBSD's sendfile (untested).
54 [Ported from Boa 0.94.14rc1]
55 * add new state, IOSHUFFLE, which utilizes sendfile (or
56 emulates it using the request's buffer, otherwise)
57 * make the default socket size 32K. The client_stream_size stays constant
58 at 8K, and the new 'buffer' size is 4K
59 Note also that the new code uses the "default" socket buffer size
60 it obtains with the first accept()ed socket.
61 * make default behavior be to leave stderr alone, but tie it
62 to cgilog otherwise
63 * add [optional, Linux-only] check for sendfile system call
64 * use --disable-sendfile to disable sendfile support
65 sendfile support for files > 100K is default, now.
66 It's significantly faster and easier than the alternative
67 * umask ~0770 before exec
68 * tie stdout to the access_log, unless there is no access_log,
69 in which case tie it to /dev/null
70 * use sensible defaults for umask (077) and (027 for CGI)
71 * add and document new parameters (CGILog and CGIumask)
72 * vast improvements to the cgi-test.cgi program, by Jon Nelson
73 and Landon Curt Noll.
74 * next 3 items by Don Mahurin (patches modified somewhat):
75 * pidfile patch
76 * default mime_types patch
77 * NCSA environment environment variables wrapped in
78 #ifdef USE_NCSA_CGI_ENV
79 * fix some escaping issues with the directory indexer
80 (Ulf Harnhammar)
81 * backport poll support from 0.95
82
83 ** Changes from 0.0.6 to 0.0.7 - 10/10/2002
84 * Added support for large files in 32 bit systems.
85 * Added support for SSL_* variables in CGIs.
86 * Added options in configuration file, to request and verify
87 a client certificate.
88 * The headers of HIC-CGIs are now parsed by the server.
89 * Corrected behavour in SIGHUP signal handling, to reread
90 the SSL related variables.
91 * Children and HIC threads are now killed using a signal, to avoid
92 unexpected errors, and memory leaks.
93
94 ** Changes from 0.0.5 to 0.0.6 - 03/10/2002
95 * Compatibility functions are now automatically included in hydra, if
96 they are not found by the configure script.
97 * Replaced the included scandir function, with the one in libc.
98 * Fixed code, which compiled fine with gcc 3.2, but didn't compile at
99 all, with any other compiler!
100 * Improved the MaxConnections directive semantics.
101 * Added a very primitive mime.types file in examples/ directory.
102
103 ** Changes from 0.0.4 to 0.0.5 - 02/10/2002
104 * If a requested CGI is not accesible then send 404 not found, instead
105 of trying to execute it.
106 * Corrected several stuff in HIC CGI handler. This allows Cookies,
107 POST data and Queries to work properly.
108
109 ** Changes from 0.0.3 to 0.0.4 - 30/09/2002
110 * Added support for If-Range, If-Match, If-None-Match HTTP/1.1 header
111 fields. The server also generates ETag headers for static content using
112 the last modified field of the file, and the file size. This makes
113 Hydra cache friendly.
114 * Added support for multiple HIC threads. This gives a boost to script generation
115 since they are no longer generated sequentially.
116
117 ** Changes from 0.0.2 to 0.0.3 - 28/09/2002
118 * Added support for dynamic modules that handle CGIs
119 internally (HIC). That way Hydra can run PHP.
120 * Fixes in CGI execution. CGIs that are not passed from aliasing
121 functions now properly set PATH_INFO and PATH_TRANSLATED.
122 (Needs further cleanup).
123 * Cleaned up SSL support. Now hydra can be compiled even if gnutls
124 is not available.
125
126 ** Changes from Boa/0.94.13 to Hydra/0.0.2 - 26/09/2002
127 * Added support for SSL 3.0 and TLS 1.0 protocols.
128 * Added support for multiple CPU's by making the server
129 run over a pool of threads.
130 * Changed the file caching code. The mmap() calls are cached until
131 the mmap list table is full.
132 * Added support for HTTP/1.1 ranges.
133 * Added support for hostname based virtual hosting.
134 Also changed the semantics of Alias, ScriptAlias and Redirect, to
135 take advantage of the host based virtual hosting.
136 * Added support for the TCP_CORK tcp option in linux.
137 * Cleaned up the CGI handling (gunzip, indexer are treated as CGIs)
138 * Enhanced grammar to handle 3 and 4 argument options.
139 * Added support for multiple directory indexes.
140 * Dropped support for gunzip.
141 * Use automake to create the distribution.
142
143 ** Changes from 0.94.12 to 0.94.13
144 * Change many instances of log_error_mesg + exit to DIE macro
145 * Change all instance of log_error_mesg (without exit) to WARN macro
146 * do a much better job of checking return values from malloc and
147 especially strdup.
148 * check results of calling umask and getrlimit
149 * server_s is no longer a global int
150 * check results of fork via switch instead of if (fork())
151 * check for getopt.h and include it if found
152 * remove unused #defines, and add WARN macro, and replace
153 many calls to log_error_mesg(..) with WARN macro
154 * fix bug in get_commonlog_time where time_offset calculation was
155 the opposite of what it should be ('-' and '+' were swapped)
156 * fix compatability bug with old and newer versions of flex/yacc
157 * add check for AC_FUNC_MMAP to configure.in
158 * fix really lame thinko in normalize_path, which would prepend the
159 results of earlier calls to results from later calls
160 * Add MaxConnections, a configuration directive which allows the
161 user to specify the maximum number of connections that Boa will
162 accept concurrently.
163 * add SERVER_ADDR and REQUEST_URI to environment of CGI
164 * handle SIGBUS during writes of data that has been memory mapped
165 * minor optimization in select.c that prevents DEAD requests from
166 being added to the block set
167 * fix bug in CGI environment script_name - closes sf.net bug #576725
168 * make 'status' variable local to requests.c, not local to every file
169 by forgetting to declare 'extern' in globals.h :-|
170 * make getsockname non-fatal, and do it every time because we may
171 need it for the CGI
172 * some minor refactoring optimizations in hash.c
173
174 ** Changes from 0.94.11 to 0.94.12
175 * Renamed Changelog ChangeLog, and moved up to top-level directory
176 * Next 3 items due in part or whole thanks to
177 Liam Widdowson
178 * when printf'ing a pid type, force to int, because it could be
179 something else on other platforms. Should probably change it to
180 a long, and use that.
181 * backported chroot commandline support from 0.95
182 * backported support for strdup, strstr, alphasort, and scandir
183 from 0.95
184 * Fixed src/Makefile.in -- it didn't remove index_dir.o
185 * backport create_temporary_file from 0.95
186 (instead of using tmpnam)
187 * Allow non-standard date format 31 September 2000 23:59:59 GMT
188 Patch by Landon Curt Noll
189 * Skip whitespace before HTTP/major.minor
190 Adapted patch from Landon Curt Noll
191 * open /dev/null first thing (affects chrooting)
192 * properly handle sigalrm -- use sigalrm_flag and sigalrm_run
193 instead of handling the signal in the signal handler
194 * update manpage slightly
195 * send 400 BAD Request when resource does not start with '/'
196 * add grp.h to boa.h's includes -- remove from boa.c and config.c
197 * removed duplicate header includes from boa.c, config.c, get.c,
198 ip.c, request.c, response.c
199 * factor out creating the server socket and dropping privs
200 into create_server_socket and drop_privs
201 * type all functions in boa.c (except main) as static
202 * set umask after opening /dev/null
203 * tie stdin/stdout to /dev/null before commandline parse
204 * removed old, unused chroot code
205 * move builds_needs_escape earlier in the startup
206 * move fork later in the startup
207 * type all c_set_* as static in config.c
208 * don't bother trying to change uid/gid (or error if the
209 requested uid/gid doesn't exist) if not UID 0
210 * return more appropriate error code when foo.html gives
211 access denied, but foo.html.gz gives some other error
212 (essentially report error associated with foo.html, not foo.html.gz)
213 * send NOT Implemented when an unknown method is attempted
214 * always attempt a 32k read right before close
215 (stopgap until blackhole can be merged)
216 * allow more than 1 space in logline between method, resource,
217 and http version
218 * don't use inline functions
219 * update configure.in so that autoconf 2.50 doesn't complain (as much)
220 * properly use VPATH and srcdir according to autoconf docs
221 * change curly-braces to parentheses in Makefilein
222 * use $^ instead of manually listing the dependencies in Makefile.in
223 * remove tests section in Makefile.in
224 * write tags not TAGS in Makefile.in
225 * Add gethostbyname and inet_aton to function checks
226 * Add code from 0.95 which checks for socket in -lsocket,
227 inet_aton in -lresolv, and gethost{by}name in -lnsl
228 * Also remove broken bc-based "how big is an unsigned int" checks:
229 assume minimum of 32 bits and check in escape.c at runtime.
230 * Added new file: README.chroot.solaris, based on a
231 modified version by Liam Widdowson
232 * Add check_struct_for.m4, which allows us to check a structure
233 for a member (found at http://www.gnu.org/software/ac-archive/
234 authored by Wes Hardaker
235 * Call "aclocal -I ." to rebuild aclocal.m4
236 * Using new check-struct-for-member autoconf macro, check
237 for tm_gmtoff and tm_zone in struct tm -- useful in
238 portability tests for localtime.
239 * Also check sockaddr_in for structure sin_len so we can set
240 it properly.
241 * index_dir.c (which ends up in boa_indexer) can now be compiled
242 with USE_LOCALTIME, and if so, it will report the local time
243 using the timezone name. Otherwise it uses UTC time and UTC
244 timezone designation.
245 * fix buglet in mmap_cache.c which shows up when under
246 heavy load by many different files.
247 Found and squashed by Michal Kara
248 * normalize paths on Aliases, log files, server root, dirmaker
249 This makes sure that paths are 'absolute'
250 * don't generate DOCUMENT_ROOT or SERVER_ROOT,
251 CGIs have no business knowing that information
252 * if CGI, chdir to the cgi's root path
253 Bug found by Matt Callaway
254 * remove ChrootPath and PidFile directives from the parser
255 (they aren't used anyway)
256 * keep track of maximum file descriptor in use to optimize call
257 to select()
258 * apply IPv6 patch from Jari Korva
259 * optimize keep-alive copy data routine
260 * try to use memcpy instead of strcpy/strcat in more places (alias.c)
261 * update .depend file
262 * use fcntl + GET_FL to get a file descriptor's flags, then
263 add or remove only the bits we want to set. This prevents
264 accidentally setting or unsettings bits we don't have anything
265 to do with inadvertantly. (removed, at least temporarily.
266 Show me a system where it is needed -- LRD)
267 * make sure to call FD_ZERO when we handle a restart
268 * in read.c, don't call boa_perror on read failure -- socket is
269 dead or messed up anyway, no reason to try to write to it.
270 * explicit .SUFFIXES in Makefile.in
271 * boa.objdump target added
272 * use @MAKE_SET@ (for when $(MAKE) != "make")
273 * add -Wundef -Wwrite-strings -Wredundant-decls -Winline to GCC_FLAGS
274 * change Paul Phillips' and Larry Doolittle's emails in source
275 * add --disable-debug, --enable-profile, --with-dmalloc, and --with-efence
276 * test for failed-but-return-was-successful setuid:
277 http://www.securityfocus.com/bid/1322
278 * use _exit not exit in CGI child
279 * always place new keepalive request on blocked list, we can't be
280 sure of the state of the active list, and since enqueue places
281 things at the *front* of the list, it doesn't do us much good
282 to place the new request on the active list anyway.
283 * update some Copyright statements for 2002
284 * When comparing the uri to an alias, only compare if
285 the uri length is greater than or equal to the length of the alias
286 * in init_script_alias, make sure to check for document_root before
287 trying to use it
288 * script_name is now just a copy of the request, rather
289 than some complicated variation on the pathname
290 * change the way the CGI environment is handled.
291 Now, it is allocated at request allocation time, and exists
292 throughout the life of the structure.
293 * check memory allocations, etc.. when creating the static
294 CGI environment and when making new CGI environment variables
295 * wait until process_option_end to call unescape_uri, clean_pathname,
296 and translate_uri
297 * remove debian package information
298 * move RedHat packaging information to contrib
299 * remove tests -- they weren't usable anyway
300 * add some new hash routines, and use djb2 (a variant on a
301 hash algorithm popularized by Dan J. Bernstein)
302 * a side-effect of the new hash routines is a bugfix,
303 involving negative return values from hash routines.
304 This has been fixed.
305 * add a routine, show_hash_stats, which is called with other
306 statistical output via sigalarm
307 * remove some duplicate prototypes from config.c
308 * make simple_itoa take an unsigned int
309 * try to make NOBLOCK handling in compat.h compatible with Solaris
310 * make sure to update current_time before calling signal handlers
311 * alter primary loop to make sure that select gets called even
312 when there are requests that are not blocking, and call fdset_update
313 and process_requests (when appropriate) after signal handlers but
314 before select to make sure that blocked requests are still handled
315 by select after a sighup. (Thanks to Karl Olsen)
316 * pull select loop into select.c
317 * poll server socket once per active connection
318 * add send_r_service_unavailable and use it when appropriate
319 * state uptime in seconds at normal program termination
320 * include sys/fcntl.h if it is found by configure
321 * fix POST bug where a content-length < 0 would cause Boa to
322 consume its full share of CPU until killed
323 Bug report by Landon Curt Noll
324 * add CGIPath configuration variable
325 based upon a patch by Landon Curt Noll
326 * add function boa_atoi, which wraps atoi, but does not
327 accept negative values. Additionally, it checks to make sure
328 the converted value and the original value are the same, avoiding
329 issues like "124.3" -> "123" and "123abc" -=> "123".
330 Either a value is an int or it isn't - no middle ground.
331 * use boa_atoi to convert content-length from client.
332 * add new #define - SINGLE_POST_LIMIT_DEFAULT, which defines
333 (in bytes) the *default* single_post_limit.
334 * single_post_limit is now in bytes.
335 * when adding aliases, only "normalize" paths that start
336 with "./" - this is a departure from previous behavior
337 * add "?" to the list of characters that it is safe to leave unescaped
338 * clean up Makefile.in of no-longer-pertinent comments
339 * add send_r_bad_gateway and use it
340 * tie stderr to either cgi_log_fd or devnullfd - either way
341 make sure stderr is a valid filehandle before cgi execution
342 * cgi_env is no longer allocated, it's part of the struct now
343 * fix bug in CgiPath logic
344 * when unable to allocate memory for an environment variable, log it
345 * add clear_common_env, which de-allocates the cgi_common_env stuff
346 [NEVER USE THIS outside of a terminal signal handler!]
347 * don't be so wasteful of memory in normalize_path
348 * adapted fix for alias expansion from Brieuc Jeunhomme
349
350 ** Changes from 0.94.10.1 to 0.94.11
351 * use LIBS in Makefile.in (which propagates from autoconf)
352 * properly free memory allocated by scandir in index_dir.c
353 * rearrange some header files and includes
354 * on reads and writes, don't check for -1, check for < 0
355 * include fix by William Meadows
356 for escape.c which fixes segfaults due to improper allocation
357 * above fix by William Meadows no longer needed;
358 escape.c and escape.h rewritten by Larry Doolittle -- requires
359 at least 32 bit words, but is correct (jdn's 1st attempt was faulty)
360
361 ** Changes from 0.94.10 to 0.94.10.1

369 * Update documentation regarding mime.types (Closes Debian #69991)
370 * Make sure documentation builds (Closes Debian #110818)
371
372 ** Changes from 0.94.8.3 to 0.94.9
373 * src/Makefile.in updated to take CFLAGS, LIBS, and LDFLAGS
374 from autoconf
375 * Update escaping rules with latest RFC
376 * unescape_uri skips fragments and also stop parsing at '?'
377 * Don't accept fd over FD_SETSIZE in request.c:get_request
378 * use backported documentation from 0.95
379 * make sure POST fd gets closed even on client cancel
380 * use backported index_dir.c from 0.95
381 * support subdirectories in ScriptAlias directories
382 * add SinglePostLimit (int, in Kilobytes) to config system
383 * check for ENOSPC on body write
384 * use environment variable TMP (or "/tmp" if not available),
385 and chdir there when boa exits.
386 * add 1-time-only hack to make a 32kB read at the end of a request
387 on POST or PUT
388 * close unused file descriptors (/dev/null in boa.c, and the
389 unused part of the pipes call in cgi.c)
390 * made Makefile.in VPATH happy
391
392 ** Changes from 0.94.8.2 to 0.94.8.3
