#ifdef COMMENTS_WITH_COMMENTS

MapUrl.c
Functions supporting mapping of URLs to VMS file specifications and VMS
specifications to URLs, uses the HTTPd rule mapping file. The number of rules
it can store is not fixed, but is limited by available memory and the
practical considerations of processing large, linear rule databases.
Comment lines may be provided by beginning a line with a '#' character.
Lines may be continued by ensuring the last character on the line is a '\'.
Virtual server syntax is the same as for authentication/authorization rules,
[[virtual-host]] (all ports of host) or [[virtual-host:virtual-port]] (
matching specified port of host) for a specific host and [[*]] to resume rules
for all virtual hosts.
Wildcards
---------
A single '*' wildcard matches intervening text up until the first character
encountered that matches the character immediately following the wildcard.
The rule
map /one/*/three/* /first/*/third/*
would map the following request path
/one/two/three/four
into
/first/two/third/four
but would not match the request path
/one/two/and-a-half/three/four
Two consecutive ('**') wildcards match intervening text up until the next
string that matches the string following the wildcard.
The rule
map /one/**/three/* /first/*/third/*
would map the following request paths
/one/two/three/four
/one/two/and-a-half/three/four
respectively into
/first/two/third/four
/first/two/and-a-half/third/four
Historically (pre v8.1) the template wildcard-matched portions of path strings
could only be substituted in the positions of corresponding wildcards in the
result string. There can be ocassions where there is not a one-to-one
relationship between these wildcard sections in the source (template) and
target (result) strings. It is sometimes useful to be able to drop one or more
strings from the template and/or change the order of substitution.
The use of 'positional wildcards' (for want of an even marginally better term)
will allow this. When a wildcard is used in the result string it may
optionally be followed by a single apostrophe character (') and a single digit
character '1'..'9'. The digit is used to indicate which of the template
wildcards is intended (first to last).
The following request path
/one/two/three/four/five.six
would be processed by the rule
pass /one/*/three/*/* /*'2/one/*'1/*'3
into the mapped path
/four/one/two/five.six
Using this notation all template wildcards must be specified 'positionally' :^)
This rule is not legal.
pass /one/*/three/* /two/*'2/four/*
Positional wildcards ONLY APPLY to PASS, MAP, REDIRECT and USER rules.
They cannot be used with EXEC, SCRIPT and UXEC rules.
Extended File Specification
---------------------------
Extended file specifications (required for ODS-5) are supported. A rule is
used to flag such paths for ODS-5 tailored processing. Things that are not
done to ODS-5 paths; case-changes and character substitution. Things that are
done to ODS-5 paths; escaping to and from the extended file specification
canonical escape syntax (i.e. '^').
Paths located on ODS-5 volumes need to have the ODS-5 rule SET against them.
set /extended/* ODS-5
It is possible to explicitly mark a path as ODS-2 also, although as this is the
default it is usually unnecessary. One situation where this might be useful is
where all paths are ODS-5 except a small minority, in which case a rule such as
the following might be used.
set /* ODS-5
set /old-path/* ODS-2
Paths derived using the USER rule are specially processed. The SYSUAF user
home directory's structure is determined using a sys$getdvi() to determined
it's ACPTYPE. Hence no explicit rule is required for these.
Mapping Rules
-------------
[[virtual-host:optional-virtual-port]]
EXEC template result [setting(s)] [conditional(s)]
EXEC (runtime)template result [setting(s)] [conditional(s)]
EXEC+ template result [setting(s)] [conditional(s)]
FAIL template [conditional(s)]
MAP template result [setting(s)] [conditional(s)]
PASS template [conditional(s)]
PASS template result [setting(s)] [conditional(s)]
PROTECT template access-control [setting(s)] [conditional(s)]
REDIRECT template result [setting(s)] [conditional(s)]
SCRIPT template result [setting(s)] [conditional(s)]
SCRIPT (runtime)template result [setting(s)] [conditional(s)]
SCRIPT+ template result [setting(s)] [conditional(s)]
SET template setting(s) [conditional(s)]
USER template result [setting(s)] [conditional(s)]
UXEC template result [setting(s)] [conditional(s)]
UXEC (runtime)template result [setting(s)] [conditional(s)]
UXEC+ template result [setting(s)] [conditional(s)]
(Somewhat awkwardly the square brackets both denote optional fields and to
literally delimit a conditional. Please do not confuse the two!)
Note that as of V8.0 path settings (anything that can be set with a SET rule)
can also follow the result string. If the rule applies and any conditional is
matched then the settings are applied to the path BEFORE the mapping is done.
PASS rules can map to a result comprising an HTTP status code (e.g. 403) with a
following textual message (including white-space). Just delimit the result
string with double or single quotes, or within curly braces. For example:
Similarly, PASS rules can map to a result comprising an 200 HTTP status code
with a following dollar symbol and CLI command string which is passed to the
script processor.
PASS /private/stuff/* "403 Can't go in there!" [!ho:my.host.name]
PASS /private/stuff/* '403 "/private/stuff/" is off-limits!' [!ho:my.host.name]
EXEC rules can be used to map both directories and file types. The former only
requires a single, trailing wildcard (example 1). The latter requires two
wildcards (examples 2 and 3). The irst to locate the script, the second to
map any path. This format can be used to globally map a file type, or confine
that mapping to specified part of a tree.
EXEC /cgi-bin/*
EXEC *.cgi* *.cgi*
EXEC /specified/path/*.cgi* /specified/path/*.cgi*
PROTECT rules can be used require authorization for for the matching path. It
complements the facility available via the WASD_CONFIG_AUTH configuration file,
providing a simpler (and to certain extent less capble) authorization schema.
See the relevant section in the description to AUTH.C module.
General Run-Time Mapping
------------------------
This is distinct from "Run-Time (RTE) Environment" scripting discussed below.
It also uses a similar rule construct and historically came much after RTE
mappings. Hence the '!' kludge mentioned shortly. The historical way to map
script file types (other than .EXE and .COM which are handled implicitly) has
been to add [DclScriptRunTime] entries to WASD_CONFIG_GLOBAL. The (very small)
disadvantage to using this is the need to completely restart the server to
apply changes. Design-wise the better place for these sorts of mappings (file
types to run-time engine) is here in WASD_CONFIG_MAP (it also allows /DO=MAP to
change these). From v8.2 we can use an RTE-like construct to specify what
non-RTE engine should be activated to process the specified script. It can be
an executable, a DCL procedure or even verb. Here's how we might activate Perl
using these rules:
exec /cgi-bin/*.pl* (!perl)/cgi-bin/*.pl*
exec /cgi-bin/*.pl* (!$perl_root:[000000]perl.exe)/cgi-bin/*.pl*
exec /cgi-bin/*.pl* (!@cgi-bin:[000000]perl.com)/cgi-bin/*.pl*
script /this_one* (!$perl_root:[000000]perl.exe)/cgi-bin/this_one.pl*
The first uses a CLI verb, the second activates a specified executable and the
last executes a DCL procedure (which in this presumably sets up some
environment before activating Perl).
Note the leading '!'. This is a bit of a kludge but not too onerous.
Mapping Logical-Name Content
----------------------------
Generally logical names only provide concealed devices into the file-system
for "root"ing some part of the web-space. That is the value of the logical
name is only used in RMS (file-system) parsing, etc.
There is a single exception. When template and result patterns contain no
wildcard(s) a one-to-one mapping if performed. For example
pass /this_is_an_example /dka0/example/this.txt
and the file content at
DKA0:[EXAMPLE]THIS.TXT
is returned.
With a one-to-one mapping the result string can represent a logical name and
the translation of that name used as the mapping element. For a PASS rule the
logical name value is used as the VMS result of the mapping (and therefore a
VMS file specification). For a REDIRECT rule it should be a URL undertood by
redirection. Here are examples:
$ DEFINE /SYSTEM /EXEC EXAMPLE_OF DKA0:[EXAMPLE]ONE.TXT
$ DEFINE /SYSTEM /EXEC EXAMPLE_GO "/wasd_root/runtime/httpd/"
pass /of EXAMPLE_OF
redirect /go EXAMPLE_GO
Using this capability, the target of a rule may be changed simply by modifying
the translated value of a logical name.
Note that the mapping rule logical name translation is case-sensitive, and so
common use of logical names (all upper-case) means the rule must be all upper
case. With all lower or mixed case the rule must specify exact case, as in
this example:
$ DEFINE /SYSTEM /EXEC "EXAMPLE_go_two" "/wasd_root/src/httpd/"
redirect /go_2 EXAMPLE_go_two
Run-Time Environment (RTE) Mapping
----------------------------------
Each persistent run-time environment must have it's own mapping environment.
This may, or may not, correspond to physically distinct directory areas. It is
the mapping rules that identify run-time environments. A parenthesized
interprester specification leads the result component of the rule. This is
first extracted and then the EXEC rule behaves as normal. Hence the following
example shows two such environments each with it's own interpreter.
exec /plbin/* (cgi-bin:[000000]perlrte.exe)/ht_root/perl_local/*
exec /pybin/* (cgi-bin:[000000]pyrte.exe)/ht_root/python_local/*
script /this_one* (cgi-bin:[000000]oneeng.exe)/cgi-bin/this.one*
The "/plbin/*" identifies request paths beginning with this string as a
hypothetical, persistent Perl run-time interpreter, with the Perl source
scripts available to it from HT_ROOT:[PERL_LOCAL]. Similarly with a
hypothetical Java Environment.
If a request with the following URI is given to the server
http://the.host.name/plbin/plsearch/web/doc/
the following components will be derived
run-time interpreter ... CGI-BIN:[000000]PERLRT.EXE
Perl source script ..... HT_ROOT:[PERL_LOCAL]PLSEARCH.PL
request path-info ...... WEB:[DOC]
Mapping User Directories
------------------------
The USER rule effectively PASSes the user's SYSUAF default device and directory
as the first wildcard substitution in the rule. Accounts that are disusered,
captive or have expired passwords are never mapped, they are always "denied
access by default". In the same way privileged accounts (those possessing
SYSPRV) cannot be mapped this way (see below for a workaround).
An example; if the user name DANIEL has the default device USER$DISK: and
default directory [DANIEL] the following request path
/~daniel/
would be mapped to the result and VMS file specification
/user$disk/daniel/www/
USER$DISK:[DANIEL.WWW]
using the following rule.
USER /~*/* /*/www/
Note the "/www" subdirectory component. It is recommended that user
directories always be mapped to a subdirectory of the physcial area. This
effectively "sandboxes" Web access to that subdirectory hierarchy, allowing the
user privacy elsewhere in the home area.
To accomodate request user paths that do not incorporate a trailing delimiter
after the username the following redirect may be used to cause the browser to
re-request with a more appropriate path.
REDIRECT /~* ///*/www/
WASD also "reverse maps" VMS specifications into paths and so requires
additional rules to provides these mappings. (Reverse mapping is required
during directory listings and error reporting.) In the above case the
following rules would actually be required (and in the stated order).
USER /~*/* /*/www/
PASS /~*/* /user$disk/*/www/*
Where user home directories are spread over multiple devices (physical or
concealed logical) a reverse-mapping rule would be required for each. Consider
the following situation, where user directories are distributed across these
devices (concealed logicals)
USER$GROUP1:
USER$GROUP2:
USER$GROUP2:
USER$OTHER:
This would require the following mapping rules (in the stated order).
USER /~*/* /*/www/
PASS /~*/* /user$group1/*/www/*
PASS /~*/* /user$group2/*/www/*
PASS /~*/* /user$group3/*/www/*
PASS /~*/* /user$other/*/www/*
Of course vanilla mapping rules may be used to provide for special cases. For
instance, if there is requirement for a particular, privileged account to have
a user mapping that could be provided as in the following (rather exagerated)
example.
PASS /~system/* /sys$common/sysmgr/www/*
USER /~*/* /*/www/
PASS /~*/* /user$disk/*/www/*
Path SETings
------------
As of v12... see MAPSET.C
[CONFIGFILE]
------------
The non-global [IncludeFile] equivalent [ConfigFile] designed for local,
per-service configuration management can include a subset of the full set of
mapping rules and settings. The following are ALLOWED:
FAIL
MAP
PASS
PROTECT
REDIRECT
SET [NO]ACCEPT=
SET CHARSET=
SET [NO]EXPIRED
SET [NO]HTML=
SET INDEX=
SET [NO]MAP=ONCE
SET QUERY-STRING=
SET RESPONSE=HEADER=
Those that cannot be used in [ConfigFile] are reported as errors during
configuration load.
MAP=ROOT Mapping
----------------
This path SETing allows for the more straight-forward mapping of virtual
service paths into a virtual-service-specific directory structure. It ensures
that for all applicable rules the specified string is prepended to the mapped
path before it is converted into a file-system specification. This remove the
need to do it with each virtual-service-specific rule. It needs to be redone
or undone (e.g. set to empty) for each virtual service or when reverting to
general rules. For example
[[a.virtual.host]]
set * map=root=/dka0/a/
# 'a' has no access to any scripts at all
pass /* /*
fail *
[[b.virtual.host]]
set * map=root=/dka0/b/
# 'b' are allowed to execute their own scripts
exec /cgi-bin/* /cgi-bin/*
pass /* /*
fail *
[[c.virtual.host]]
# 'c' is allowed to execute the general server scripts
exec /cgi-bin/* /cgi-bin/*
set * map=root=/dka0/c/
pass /* /*
fail *
[[*]]
set * map=root=
exec /cgi-bin/* /cgi-bin/*
pass /* /web/*
fail *
PERSONA-based User Scripting
----------------------------
For use with VMS V6.2 and greater (or 6.0 and 6.1 if compiled with the
PERSONA_MACRO build option), with the /PERSONA qualifier active.
The following rule set will allow user account based scripting.
SET /~*/www/cgi-bin/* script=as=~
UXEC /~*/cgi-bin/* /*/www/cgi-bin/*
USER /~*/* /*/www/*
REDIRECT /~* /~*/
PASS /~*/* /dka0/users/*/*
DECnet-based User Scripting
---------------------------
If DECnet/OSU scripting is enabled then the following rule will activate a
script in the specified user's directory (all other things being equal).
Always map to some unique and specific subdirectory of the home directory.
exec /~*/cgi-bin/* /0""::/where/ever/*/cgi-bin/*
It's a little like the user-mapping rules:
pass /~* /where/ever/*
Mapping Conditionals
--------------------
***************
* OBSOLESCENT *
***************
ALTHOUGH MAPPING RULE CONDITIONALS DESCRIBED BELOW WILL CONTINUE
TO BE SUPPORTED IN THE FORESEEABLE FUTURE THE PREFERED POST-7.2
MECHANISM FOR CONDITIONAL PROCESSING OF RULES IS PROVIDED BY THE
META-CONFIG CONDITIONAL STRUCTURES AND DIRECTIVES.
Conditionals are new to v4.4 and allow mapping rules to be applied
conditionally! That is, the conditionals contain strings that are matched to
specific elements of the request and only if matched are the corresponding
rules applied. The conditionals may contain the '*' and '%' wildcards, and
optionally be negated by an '!' at the start of the conditional string.
Conditionals must follow the rule and are delimited by '[' and ']'. Multiple,
space-separated conditions may be included within one '[...]'. This behaves as
a logical OR (i.e. the condition is true if only one is matched). Multiple
'[...]' conditionals may be included against a rule. These act as a logical
AND (i.e. all must have at least one condition matched). The result of an
entire conditional may be optionally negated by prefixing the '[' with a '!'.
If a conditional is not met the line is completely ignored. Conditional rules
are not used for 'backward' translation (i.e. from VMS to URL path) so another
rule must exist somewhere to do these mappings. Conditional rules are only
used by the HTTPd server, they are completely ignored by any scripts using the
MapUrl.c module.

The host-mask ('HM') directive is a dotted-decimal network address, a slash,
then a dotted-decimal mask. For example "[HM:131.185.250.0/255.255.255.192]".
This has a 6 bit subnet. It operates by bitwise-ANDing the client host address
with the mask, bitwise-ANDing the network address supplied with the mask, then
comparing the two results for equality. Using the above example the host
131.185.250.250 would be accepted, but 131.185.250.50 would be rejected.

/*
This overly-long function (sorry) is not AST reentrant, but when executed
within the context of the HTTPd, is executed either without the possibility of
AST interruption, or during AST processing and so provides atomic
functionality. Pointers to any strings returned must be used immediately
(before leaving AST context), or copied into storage maintained by the calling
routine.
Maps from URL format to VMS file specification, and REVERSE-MAPS from VMS file
specification to URL format. Maps scripts.
Always returns a pointer to char. An error message is detected by being
returned as a pointer to a string beginning with a null-character! The
message begins from character one.
Call with 'PathPtr' pointing at a string containing the URL path and 'VmsPtr'
pointing to the storage to contain the mapped VMS equivalent.
Call with 'VmsPtr' pointing to a VMS file specification (dev:[dir]file.ext)
and 'PathPtr' pointing to an empty string, used as storage to contain the
REVERSE-MAPPED file specification.
Call with 'PathPtr' pointing at a string containing the URL path, 'VmsPtr'
pointing to storage to contain the mapped VMS equivalent, 'ScriptPtr' pointing
to storage for the URL format script path and 'ScriptVmsPtr' pointing to
storage to contain the VMS specification of the script procedure/image.
The MapUrl_Map() just wraps MapUrl__Map() so that it's function can be WATCHed.
