|
---|

|
---|
| 84 | finished changes to browsing support
|
---|

---|

|
---|
| 88 | - redesigned browsing support (although it's not finished so

---|
| 89 | won't currently work ;-)
|
---|

[606] | 91 | Revision 1.32 1999/09/21 11:28:45 sjboddie
|
---|
| 92 | tidied up file locking
|
---|
| 93 |
|

[595] | 94 | Revision 1.31 1999/09/16 21:38:17 sjboddie
|
---|
| 95 | added some file locking stuff for logging. Windows still needs to
|
---|
| 96 | be done.
|
---|
| 97 |
|
---|
[533] | 98 | Revision 1.30 1999/09/07 04:56:58 sjboddie
|
---|

|
---|
| 100 |
|
---|
[530] | 101 | Revision 1.29 1999/09/03 10:02:30 rjmcnab
|
---|
| 102 | Made the page parameters configurable. Now the page parameters must
|
---|
| 103 | correspond to cgi arguments in name and value (ie language=zh should now
|
---|
| 104 | be l=zh) which makes things more consistent anyway. Removed a couple of
|
---|
| 105 | specialised NZDL page parameters.
|
---|
| 106 |
|
---|
| 107 | Moved the combining of the cgi arguments so that the receptionist does
|
---|
| 108 | all the configuration now.
|
---|
| 109 |
|
---|
| 110 | Made the macro precedence configurable.
|
---|
| 111 |
|
---|
| 112 | Made cgi arguments totally configurable. Now any piece of information about
|
---|
| 113 | a cgi argument can be configured meaning that cgi arguments can be declared
|
---|
| 114 | from the configuration file.
|
---|
| 115 |
|
---|
| 116 | Removed the argdefault configuration argument. This should now be done
|
---|
| 117 | using cgiarg.
|
---|
| 118 |
|
---|
[526] | 119 | Revision 1.28 1999/09/03 04:39:46 rjmcnab
|
---|
| 120 | Made cookies and logs optional (they are turned off by default). To
|
---|
| 121 | turn them on put
|
---|
| 122 |
|
---|
| 123 | usecookies true
|
---|
| 124 | logcgiargs true
|
---|
| 125 |
|
---|
| 126 | in your configuration file.
|
---|
| 127 |
|
---|
[512] | 128 | Revision 1.27 1999/09/02 00:27:21 rjmcnab
|
---|
| 129 | A few small things.
|
---|
| 130 |
|
---|
[468] | 131 | Revision 1.26 1999/08/25 04:43:06 sjboddie
|
---|
| 132 | made FilterRequest_t::docSet an array rather than a set
|
---|
| 133 |
|
---|
[463] | 134 | Revision 1.25 1999/08/20 00:59:01 sjboddie
|
---|
| 135 | -fixed up location redirection
|
---|
| 136 | -added some usage logging, also now set a GSDL_UID cookie. Logging
|
---|
| 137 | does NOT presently lock the log file while it's in use. That has yet
|
---|
| 138 | to be done.
|
---|
| 139 |
|
---|
[456] | 140 | Revision 1.24 1999/08/13 04:16:42 sjboddie
|
---|
| 141 | added some collection-level metadata stuff
|
---|
| 142 |
|
---|
[451] | 143 | Revision 1.23 1999/08/11 23:28:59 sjboddie
|
---|
| 144 | added support for html classifier (i.e. the hp argumant now must be
|
---|
| 145 | translated too).
|
---|
| 146 |
|
---|
[446] | 147 | Revision 1.22 1999/08/10 22:45:21 sjboddie

|
---|
| 152 | to receptionist
|
---|
| 153 |
|
---|
[418] | 154 | Revision 1.20 1999/07/30 02:13:09 sjboddie
|
---|
| 155 | -added collectinfo argument to some functions
|
---|
| 156 | -made some function prototypes virtual
|
---|
| 157 |
|
---|
[388] | 158 | Revision 1.19 1999/07/15 06:02:05 rjmcnab
|
---|
| 159 | Moved the setting of argsinfo into the constructor. Added the configuration
|
---|
| 160 | command argdefault (as used by the actions). Added code to output the
|
---|
| 161 | correct charset based on the page encoding so that the user does not need
|
---|
| 162 | to specify the encoding used for a particular page.
|
---|
| 163 |
|
---|
[366] | 164 | Revision 1.18 1999/07/11 01:05:20 rjmcnab

|
---|
| 169 |
|
---|

|
---|
| 178 |
|
---|
[261] | 179 | Revision 1.13 1999/06/08 04:29:31 sjboddie
|
---|
| 180 | added argsinfo to the call to check_cgiargs to make it easy to set
|
---|
| 181 | args to their default if they're found to be screwed up
|
---|
| 182 |
|
---|
[248] | 183 | Revision 1.12 1999/04/30 01:59:42 sjboddie
|
---|
| 184 | lots of stuff - getting documentaction working (documentaction replaces
|
---|
| 185 | old browseaction)
|
---|
| 186 |
|
---|
[206] | 187 | Revision 1.11 1999/03/25 03:06:43 sjboddie
|
---|
| 188 |
|
---|
| 189 | altered receptionist slightly so it now passes *collectproto to
|
---|
| 190 | define_internal_macros and define_external_macros - need it
|
---|
| 191 | for browseaction
|
---|
| 192 |
