Branch: MAIN
Changes since 1.26: +1 -0 lines
*** empty log message ***

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

287 * unescape_uri skips fragments and also stop parsing at '?'
288 * Don't accept fd over FD_SETSIZE in request.c:get_request
289 * use backported documentation from 0.95
290 * make sure POST fd gets closed even on client cancel

292 * support subdirectories in ScriptAlias directories
293 * add SinglePostLimit (int, in Kilobytes) to config system
294 * check for ENOSPC on body write
295 * use environment variable TMP (or "/tmp" if not available),
296 and chdir there when boa exits.
297 * add 1-time-only hack to make a 32kB read at the end of a request
298 on POST or PUT
299 * close unused file descriptors (/dev/null in boa.c, and the
300 unused part of the pipes call in cgi.c)
301 * made Makefile.in VPATH happy
302
303 ** Changes from 0.94.8.2 to 0.94.8.3
