Branch: MAIN
Changes since 1.3: +1 -0 lines
*** empty log message ***

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

266    
267     ** Changes from 0.94.8.1 to 0.94.8.2

277     * unlink temporary file immediately following creation
278     * implement maximum # of active connections at 10 less than RLIMIT_NOFILE
279     to avoid or eliminate crashes resulting from running out of
280     file descriptors
281     * Fix thinko in POST
