*** empty log message ***

1 nmav 1.24 ** Changes from 0.0.5 to 0.0.6 - 03/10/2002
2 nmav 1.21 * Compatibility functions are now automatically included in hydra, if
3     they are not found by the configure script.
4 nmav 1.22 * Replaced the included scandir function, with the one in libc.
5 nmav 1.23 * Fixed code, which compiled fine with gcc 3.2, but didn't compile at
6 nmav 1.22 all, with any other compiler!
7 nmav 1.23 * Improved the MaxConnections directive semantics.
8 nmav 1.21
9 nmav 1.20 ** Changes from 0.0.4 to 0.0.5 - 02/10/2002
10 nmav 1.18 * If a requested CGI is not accesible then send 404 not found, instead
11     of trying to execute it.
12 nmav 1.19 * Corrected several stuff in HIC CGI handler. This allows Cookies,
13     POST data and Queries to work properly.
14 nmav 1.18
15 nmav 1.17 ** Changes from 0.0.3 to 0.0.4 - 30/09/2002
16 nmav 1.14 * Added support for If-Range, If-Match, If-None-Match HTTP/1.1 header
17     fields. The server also generates ETag headers for static content using
18 nmav 1.15 the last modified field of the file, and the file size. This makes
19     Hydra cache friendly.
20 nmav 1.16 * Added support for multiple HIC threads. This gives a boost to script generation
21 nmav 1.22 since they are no longer generated sequentially.
22 nmav 1.14
23 nmav 1.13 ** Changes from 0.0.2 to 0.0.3 - 28/09/2002
24 nmav 1.11 * Added support for dynamic modules that handle CGIs
25     internally (HIC). That way Hydra can run PHP.
26     * Fixes in CGI execution. CGIs that are not passed from aliasing
27     functions now properly set PATH_INFO and PATH_TRANSLATED.
28     (Needs further cleanup).
29 nmav 1.12 * Cleaned up SSL support. Now hydra can be compiled even if gnutls
30     is not available.
31 nmav 1.11
32 nmav 1.9 ** Changes from Boa/0.94.13 to Hydra/0.0.2 - 26/09/2002
33 nmav 1.2 * Added support for SSL 3.0 and TLS 1.0 protocols.
34     * Added support for multiple CPU's by making the server
35     run over a pool of threads.
36     * Changed the file caching code. The mmap() calls are cached until
37     the mmap list table is full.
38     * Added support for HTTP/1.1 ranges.
39 nmav 1.4 * Added support for hostname based virtual hosting.
40 nmav 1.5 Also changed the semantics of Alias, ScriptAlias and Redirect, to
41     take advantage of the host based virtual hosting.
42 nmav 1.3 * Added support for the TCP_CORK tcp option in linux.
43     * Cleaned up the CGI handling (gunzip, indexer are treated as CGIs)
44 nmav 1.10 * Enhanced grammar to handle 3 and 4 argument options.
45 nmav 1.7 * Added support for multiple directory indexes.
46     * Dropped support for gunzip.
47 nmav 1.8 * Use automake to create the distribution.
48 nmav 1.2
49 nmav 1.1 ** Changes from 0.94.12 to 0.94.13
50     * Change many instances of log_error_mesg + exit to DIE macro
51     * Change all instance of log_error_mesg (without exit) to WARN macro
52     * do a much better job of checking return values from malloc and
53     especially strdup.
54     * check results of calling umask and getrlimit
55     * server_s is no longer a global int
56     * check results of fork via switch instead of if (fork())
57     * check for getopt.h and include it if found
58     * remove unused #defines, and add WARN macro, and replace
59     many calls to log_error_mesg(..) with WARN macro
60     * fix bug in get_commonlog_time where time_offset calculation was
61     the opposite of what it should be ('-' and '+' were swapped)
62     * fix compatability bug with old and newer versions of flex/yacc
63     * add check for AC_FUNC_MMAP to configure.in
64     * fix really lame thinko in normalize_path, which would prepend the
65     results of earlier calls to results from later calls
66     * Add MaxConnections, a configuration directive which allows the
67     user to specify the maximum number of connections that Boa will
68     accept concurrently.
69     * add SERVER_ADDR and REQUEST_URI to environment of CGI
70     * handle SIGBUS during writes of data that has been memory mapped
71     * minor optimization in select.c that prevents DEAD requests from
72     being added to the block set
73     * fix bug in CGI environment script_name - closes sf.net bug #576725
74     * make 'status' variable local to requests.c, not local to every file
75     by forgetting to declare 'extern' in globals.h :-|
76     * make getsockname non-fatal, and do it every time because we may
77     need it for the CGI
78     * some minor refactoring optimizations in hash.c
79    
80     ** Changes from 0.94.11 to 0.94.12
81     * Renamed Changelog ChangeLog, and moved up to top-level directory
82     * Next 3 items due in part or whole thanks to
83     Liam Widdowson
84     * when printf'ing a pid type, force to int, because it could be
85     something else on other platforms. Should probably change it to
86     a long, and use that.
87     * backported chroot commandline support from 0.95
88     * backported support for strdup, strstr, alphasort, and scandir
89     from 0.95
90     * Fixed src/Makefile.in -- it didn't remove index_dir.o
91     * backport create_temporary_file from 0.95
92     (instead of using tmpnam)
93     * Allow non-standard date format 31 September 2000 23:59:59 GMT
94     Patch by Landon Curt Noll
95     * Skip whitespace before HTTP/major.minor
96     Adapted patch from Landon Curt Noll
97     * open /dev/null first thing (affects chrooting)
98     * properly handle sigalrm -- use sigalrm_flag and sigalrm_run
99     instead of handling the signal in the signal handler
100     * update manpage slightly
101     * send 400 BAD Request when resource does not start with '/'
102     * add grp.h to boa.h's includes -- remove from boa.c and config.c
103     * removed duplicate header includes from boa.c, config.c, get.c,
104     ip.c, request.c, response.c
105     * factor out creating the server socket and dropping privs
106     into create_server_socket and drop_privs
107     * type all functions in boa.c (except main) as static
108     * set umask after opening /dev/null
109     * tie stdin/stdout to /dev/null before commandline parse
110     * removed old, unused chroot code
111     * move builds_needs_escape earlier in the startup
112     * move fork later in the startup
113     * type all c_set_* as static in config.c
114     * don't bother trying to change uid/gid (or error if the
115     requested uid/gid doesn't exist) if not UID 0
116     * return more appropriate error code when foo.html gives
117     access denied, but foo.html.gz gives some other error
118     (essentially report error associated with foo.html, not foo.html.gz)
119     * send NOT Implemented when an unknown method is attempted
120     * always attempt a 32k read right before close
121     (stopgap until blackhole can be merged)
122     * allow more than 1 space in logline between method, resource,
123     and http version
124     * don't use inline functions
125     * update configure.in so that autoconf 2.50 doesn't complain (as much)
126     * properly use VPATH and srcdir according to autoconf docs
127     * change curly-braces to parentheses in Makefilein
128     * use $^ instead of manually listing the dependencies in Makefile.in
129     * remove tests section in Makefile.in
130     * write tags not TAGS in Makefile.in
131     * Add gethostbyname and inet_aton to function checks
132     * Add code from 0.95 which checks for socket in -lsocket,
133     inet_aton in -lresolv, and gethost{by}name in -lnsl
134     * Also remove broken bc-based "how big is an unsigned int" checks:
135     assume minimum of 32 bits and check in escape.c at runtime.
136     * Added new file: README.chroot.solaris, based on a
137     modified version by Liam Widdowson
138     * Add check_struct_for.m4, which allows us to check a structure
139     for a member (found at http://www.gnu.org/software/ac-archive/
140     authored by Wes Hardaker
141     * Call "aclocal -I ." to rebuild aclocal.m4
142     * Using new check-struct-for-member autoconf macro, check
143     for tm_gmtoff and tm_zone in struct tm -- useful in
144     portability tests for localtime.
145     * Also check sockaddr_in for structure sin_len so we can set
146     it properly.
147     * index_dir.c (which ends up in boa_indexer) can now be compiled
148     with USE_LOCALTIME, and if so, it will report the local time
149     using the timezone name. Otherwise it uses UTC time and UTC
150     timezone designation.
151     * fix buglet in mmap_cache.c which shows up when under
152     heavy load by many different files.
153     Found and squashed by Michal Kara
154     * normalize paths on Aliases, log files, server root, dirmaker
155     This makes sure that paths are 'absolute'
156     * don't generate DOCUMENT_ROOT or SERVER_ROOT,
157     CGIs have no business knowing that information
158     * if CGI, chdir to the cgi's root path
159     Bug found by Matt Callaway
160     * remove ChrootPath and PidFile directives from the parser
161     (they aren't used anyway)
162     * keep track of maximum file descriptor in use to optimize call
163     to select()
164     * apply IPv6 patch from Jari Korva
165     * optimize keep-alive copy data routine
166     * try to use memcpy instead of strcpy/strcat in more places (alias.c)
167     * update .depend file
168     * use fcntl + GET_FL to get a file descriptor's flags, then
169     add or remove only the bits we want to set. This prevents
170     accidentally setting or unsettings bits we don't have anything
171     to do with inadvertantly. (removed, at least temporarily.
172     Show me a system where it is needed -- LRD)
173     * make sure to call FD_ZERO when we handle a restart
174     * in read.c, don't call boa_perror on read failure -- socket is
175     dead or messed up anyway, no reason to try to write to it.
176     * explicit .SUFFIXES in Makefile.in
177     * boa.objdump target added
178     * use @MAKE_SET@ (for when $(MAKE) != "make")
179     * add -Wundef -Wwrite-strings -Wredundant-decls -Winline to GCC_FLAGS
180     * change Paul Phillips' and Larry Doolittle's emails in source
181     * add --disable-debug, --enable-profile, --with-dmalloc, and --with-efence
182     * test for failed-but-return-was-successful setuid:
183     http://www.securityfocus.com/bid/1322
184     * use _exit not exit in CGI child
185     * always place new keepalive request on blocked list, we can't be
186     sure of the state of the active list, and since enqueue places
187     things at the *front* of the list, it doesn't do us much good
188     to place the new request on the active list anyway.
189     * update some Copyright statements for 2002
190     * When comparing the uri to an alias, only compare if
191     the uri length is greater than or equal to the length of the alias
192     * in init_script_alias, make sure to check for document_root before
193     trying to use it
194     * script_name is now just a copy of the request, rather
195     than some complicated variation on the pathname
196     * change the way the CGI environment is handled.
197     Now, it is allocated at request allocation time, and exists
198     throughout the life of the structure.
199     * check memory allocations, etc.. when creating the static
200     CGI environment and when making new CGI environment variables
201     * wait until process_option_end to call unescape_uri, clean_pathname,
202     and translate_uri
203     * remove debian package information
204     * move RedHat packaging information to contrib
205     * remove tests -- they weren't usable anyway
206     * add some new hash routines, and use djb2 (a variant on a
207     hash algorithm popularized by Dan J. Bernstein)
208     * a side-effect of the new hash routines is a bugfix,
209     involving negative return values from hash routines.
210     This has been fixed.
211     * add a routine, show_hash_stats, which is called with other
212     statistical output via sigalarm
213     * remove some duplicate prototypes from config.c
214     * make simple_itoa take an unsigned int
215     * try to make NOBLOCK handling in compat.h compatible with Solaris
216     * make sure to update current_time before calling signal handlers
217     * alter primary loop to make sure that select gets called even
218     when there are requests that are not blocking, and call fdset_update
219     and process_requests (when appropriate) after signal handlers but
220     before select to make sure that blocked requests are still handled
221     by select after a sighup. (Thanks to Karl Olsen)
222     * pull select loop into select.c
223     * poll server socket once per active connection
224     * add send_r_service_unavailable and use it when appropriate
225     * state uptime in seconds at normal program termination
226     * include sys/fcntl.h if it is found by configure
227     * fix POST bug where a content-length < 0 would cause Boa to
228     consume its full share of CPU until killed
229     Bug report by Landon Curt Noll
230     * add CGIPath configuration variable
231     based upon a patch by Landon Curt Noll
232     * add function boa_atoi, which wraps atoi, but does not
233     accept negative values. Additionally, it checks to make sure
234     the converted value and the original value are the same, avoiding
235     issues like "124.3" -> "123" and "123abc" -=> "123".
236     Either a value is an int or it isn't - no middle ground.
237     * use boa_atoi to convert content-length from client.
238     * add new #define - SINGLE_POST_LIMIT_DEFAULT, which defines
239     (in bytes) the *default* single_post_limit.
240     * single_post_limit is now in bytes.
241     * when adding aliases, only "normalize" paths that start
242     with "./" - this is a departure from previous behavior
243     * add "?" to the list of characters that it is safe to leave unescaped
244     * clean up Makefile.in of no-longer-pertinent comments
245     * add send_r_bad_gateway and use it
246     * tie stderr to either cgi_log_fd or devnullfd - either way
247     make sure stderr is a valid filehandle before cgi execution
248     * cgi_env is no longer allocated, it's part of the struct now
249     * fix bug in CgiPath logic
250     * when unable to allocate memory for an environment variable, log it
251     * add clear_common_env, which de-allocates the cgi_common_env stuff
252     [NEVER USE THIS outside of a terminal signal handler!]
253     * don't be so wasteful of memory in normalize_path
254     * adapted fix for alias expansion from Brieuc Jeunhomme
255    
256     ** Changes from 0.94.10.1 to 0.94.11
257     * use LIBS in Makefile.in (which propagates from autoconf)
258     * properly free memory allocated by scandir in index_dir.c
259     * rearrange some header files and includes
260     * on reads and writes, don't check for -1, check for < 0
261     * include fix by William Meadows
262     for escape.c which fixes segfaults due to improper allocation
263     * above fix by William Meadows no longer needed;
264     escape.c and escape.h rewritten by Larry Doolittle -- requires
265     at least 32 bit words, but is correct (jdn's 1st attempt was faulty)
266    
267     ** Changes from 0.94.10 to 0.94.10.1
268     * Actually update the SERVER_VERSION in src/defines.h
269    
270     ** Changes from 0.94.9 to 0.94.10
271     * Fixes escaping rules
272     * Fixes segfault when directory_index is undefined and
273     directory needs to be generated
274     * adds dummy signal handlers for SIGUSR1 and SIGUSR2 (Closes SF #425921)
275     * Update documentation regarding mime.types (Closes Debian #69991)
276     * Make sure documentation builds (Closes Debian #110818)
277    
278     ** Changes from 0.94.8.3 to 0.94.9
279     * src/Makefile.in updated to take CFLAGS, LIBS, and LDFLAGS
280     from autoconf
281     * Update escaping rules with latest RFC
282     * unescape_uri skips fragments and also stop parsing at '?'
283     * Don't accept fd over FD_SETSIZE in request.c:get_request
284     * use backported documentation from 0.95
285     * make sure POST fd gets closed even on client cancel
286     * use backported index_dir.c from 0.95
287     * support subdirectories in ScriptAlias directories
288     * add SinglePostLimit (int, in Kilobytes) to config system
289     * check for ENOSPC on body write
290     * use environment variable TMP (or "/tmp" if not available),
291     and chdir there when boa exits.
292     * add 1-time-only hack to make a 32kB read at the end of a request
293     on POST or PUT
294     * close unused file descriptors (/dev/null in boa.c, and the
295     unused part of the pipes call in cgi.c)
296     * made Makefile.in VPATH happy
297    
298     ** Changes from 0.94.8.2 to 0.94.8.3
299     * Move unescape_uri *before* clean_pathname to prevent
300     encoding of / and .. in pathname
301     * wrap execution of GUNZIP in cgi.c with #ifdef GUNZIP
302     * stop parsing when fragment found in URL ('#')
303    
304     ** Changes from 0.94.8.1 to 0.94.8.2

366     * Replacement of sprintf with strlen/memcpy or strcpy/strcat
367     wherever possible
368     * Significant rearrangement in alias.c, minor functional differences
