.SH DESCRIPTION
|
|
.PP
|
|
.B insert_webindex
|
|
inserts, into the webindex database, the data from a parsed web index
|
|
listing.
|
|
It is normally run from the master control program,
|
|
.BR arcontrol (n),
|
|
as part of the update phase of the Archie update cycle. It may also be invoked
|
|
from the command line.
|
|
.PP
|
|
The file to be inserted must be in Archie webindex parse output format, such as
|
|
is
|
|
generated by the Archie webindex parser,
|
|
.BR parse_webindex .
|
|
The output of this program is placed directly into the webindex catalog.
|
|
|
|
.B insert_webindex
|
|
updates the webindex database in several phases, in order to
|
|
minimize the critical period where interruption of the insertion could
|
|
cause the database to be corrupted. However, to prevent the possibility
|
|
of this happening at all, the program should not be interrupted at any time.
|
|
.PP
|
|
.B insert_webindex
|
|
will not attempt to update a site which is listed as
|
|
.I active
|
|
in the host databases, nor overwrite an existing data file in the
|
|
webindex database. Error conditions, such as a full file system, are also
|
|
detected before the webindex database is modified.
|
|
.PP
|
|
This program also modifies the webindex entry, in the auxiliary host database,
|
|
corresponding to this site.
|
|
.PP
|
|
When invoking this program from the command line, care should be taken to
|
|
ensure that no other processes are modifying the webindex catalog.
|
|
The exclusive locking mechanism provided by the
|
|
.BR update_webindex (n)
|
|
program, which invokes
|
|
.B insert_webindex
|
|
in normal operation, will not be available in the command line
|
|
invocation.
|
|
|
|
.SH OPTIONS
|
|
.PP
|
|
The following option must be supplied:
|
|
.RS
|
|
.TP
|
|
.B \-i
|
|
Input file name
|
|
.RE
|
|
.PP
|
|
Additionally, the following options are accepted:
|
|
.RS
|
|
.TP
|
|
.BI \-M \ <dir>
|
|
The name of the master Archie database directory. If not
|
|
specified, the program looks in the directory
|
|
.BR ~archie/db ,
|
|
then
|
|
.BR ./db .
|
|
.TP
|
|
.BI \-w \ <dir>
|
|
The name of the directory in which the Archie webindex
|
|
catalog resides. This parameter overrides the internally generated
|
|
catalog name
|
|
.B ~archie/db/webindex
|
|
and the
|
|
.B \-M
|
|
option, if specified.
|
|
.TP
|
|
.BI \-h \ <dir>
|
|
The name of the Archie host database directory. If not
|
|
specified, the program will first default to
|
|
.BR ~archie/db/host_db ,
|
|
then
|
|
.BR ./host_db .
|
|
.TP
|
|
.BI \-t \ <dir>
|
|
Set the name of directory used for temporary files. By
|
|
default the program uses
|
|
.B ~archie/db/tmp.
|
|
.TP
|
|
.BI \-I \ <size>
|
|
Set the minimum size for a site file to be indexed.
|
|
The size is in bytes.
|
|
If the size of the site file is greater or equal to this size
|
|
a .idx file will accompany this site file to speed up
|
|
searches in it. By default this size is
|
|
500000 bytes.
|
|
.TP
|
|
.BI \-v
|
|
Verbose mode. Tells you what it is doing.
|
|
.TP
|
|
.B \-l
|
|
Write any user output to the default log file
|
|
.B ~archie/logs/archie.log.
|
|
If desired, this can be overridden with the
|
|
.B \-L
|
|
option. Errors will by default be written to
|
|
.I stderr.
|
|
.TP
|
|
.BI \-L \ <logfile>
|
|
The name of the file to be used for logging information.
|
|
Note that debugging information is also written to the
|
|
log file. This implies the
|
|
.B \-l
|
|
option as well.

.SH BUGS
|
|
Unlike the previous Archie system, corruption of the database is limited
|
|
to the single site when the program is aborted
|
|
prematurely.If an insert ends
|
|
before the site is created then the data in the db/webindex_db/start_db.*
|
|
database will not be accurate but will not affect other insertions. Your
|
|
queries will output error messages in the logs files reflecting the
|
|
inconsistency.
