*** empty log message ***

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

251     directory needs to be generated
252     * adds dummy signal handlers for SIGUSR1 and SIGUSR2 (Closes SF #425921)
253     * Update documentation regarding mime.types (Closes Debian #69991)
254     * Make sure documentation builds (Closes Debian #110818)
255    
256     ** Changes from 0.94.8.3 to 0.94.9
257     * src/Makefile.in updated to take CFLAGS, LIBS, and LDFLAGS
258     from autoconf
259     * Update escaping rules with latest RFC
260     * unescape_uri skips fragments and also stop parsing at '?'
261     * Don't accept fd over FD_SETSIZE in request.c:get_request
262     * use backported documentation from 0.95
263     * make sure POST fd gets closed even on client cancel
264     * use backported index_dir.c from 0.95
265     * support subdirectories in ScriptAlias directories
266     * add SinglePostLimit (int, in Kilobytes) to config system
267     * check for ENOSPC on body write
268     * use environment variable TMP (or "/tmp" if not available),
269     and chdir there when boa exits.
270     * add 1-time-only hack to make a 32kB read at the end of a request
271     on POST or PUT
272     * close unused file descriptors (/dev/null in boa.c, and the
273     unused part of the pipes call in cgi.c)
274     * made Makefile.in VPATH happy
275    
276     ** Changes from 0.94.8.2 to 0.94.8.3
277     * Move unescape_uri *before* clean_pathname to prevent
278     encoding of / and .. in pathname
279     * wrap execution of GUNZIP in cgi.c with #ifdef GUNZIP
280     * stop parsing when fragment found in URL ('#')
281
