Changes since 1.49.2.15: +1 -0 lines
Some optimizations in header parsing

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

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