-.IX Title "MAKEHISTORY 8"
-.TH MAKEHISTORY 8 "2008-04-06" "INN 2.4.5" "InterNetNews Documentation"
-.SH "NAME"
-makehistory \- Initialize or rebuild INN history database
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-\&\fBmakehistory\fR [\fB\-abeFIOx\fR] [\fB\-f\fR \fIfilename\fR] [\fB\-l\fR \fIcount\fR]
-[\fB\-T\fR \fItmpdir\fR] [\fB\-s\fR \fIsize\fR]
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-\&\fBmakehistory\fR rebuilds the \fIhistory\fR\|(5) text file, which contains a list of
-Message-IDs of articles already seen by the server. It can also be used
-to rebuild the overview database. Note that the \fIdbz\fR\|(3) indexes for the
-history file are rebuilt by \fImakedbz\fR\|(8), not by \fBmakehistory\fR as in
-earlier versions of \s-1INN\s0.
-.PP
-The default location of the history text file is \fIpathdb\fR/history; to
-specify an alternate location, use the \fB\-f\fR flag.
-.PP
-By default, \fBmakehistory\fR will scan the entire spool, using the storage
-manager, and write a history line for every article. To also generate
-overview information, use the \fB\-O\fR flag.
-.PP
-\&\s-1WARNING:\s0 If you're trying to rebuild the overview database, be sure to
-stop \fIinnd\fR\|(8) and delete or zero out the existing database before you start
-for the best results. An overview rebuild should not be done while the
-server is running. Unless the existing overview is deleted, you may end
-up with problems like out-of-order overview entries, excessively large
-overview buffers, and the like.
-.PP
-If \fIovmethod\fR in \fIinn.conf\fR is \f(CW\*(C`ovdb\*(C'\fR, you must have the ovdb processes
-running while rebuilding overview. ovdb needs them available while
-writing overview entries. You can start them by hand separate from the
-rest of the server by running \fBovdb_init\fR; see \fIovdb_init\fR\|(8) for more
-details.
-.SH "OPTIONS"
-.IX Header "OPTIONS"
-.IP "\fB\-a\fR" 4
-.IX Item "-a"
-Append to the history file rather than generating a new one. If you
-append to the main history file, make sure \fIinnd\fR\|(8) is throttled or not
-running, or you can corrupt the history.
-.IP "\fB\-b\fR" 4
-.IX Item "-b"
-Delete any messages found in the spool that do not have valid Message-ID
-headers in them.
-.IP "\fB\-e\fR" 4
-.IX Item "-e"
-Compute Bytes headers which is used for overview data. This option is valid
-only if \fB\-O\fR flag is specified and \fIoverview.fmt\fR includes \f(CW\*(C`Bytes:\*(C'\fR.
-.IP "\fB\-f\fR \fIfilename\fR" 4
-.IX Item "-f filename"
-Rather than writing directly to \fIpathdb\fR/history, instead write to
-\&\fIfilename\fR.
-.IP "\fB\-F\fR" 4
-.IX Item "-F"
-Fork a separate process to flush overview data to disk rather than doing
-it directly. The advantage of this is that it allows \fBmakehistory\fR to
-continue to collect more data from the spool while the first batch of data
-is being written to the overview database. The disadvantage is that up to
-twice as much temporary disk space will be used for the generated overview
-data. This option only makes sense in combination with \fB\-O\fR. With
-\&\f(CW\*(C`buffindexed\*(C'\fR, the \f(CW\*(C`overchan\*(C'\fR program is invoked to write overview.
-.IP "\fB\-I\fR" 4
-.IX Item "-I"
-Don't store overview data for articles numbered lower than the lowest
-article number in \fIactive\fR. This is useful if there are for whatever
-reason old articles on disk that shouldn't be available to readers or put
-into the overview database.
-.IP "\fB\-l\fR \fIcount\fR" 4
-.IX Item "-l count"
-This option specifies how many articles to process before writing the
-accumulated overview information out to the overview database. The
-default is \f(CW10000\fR. Since overview write performance is faster with
-sorted data, each \*(L"batch\*(R" gets sorted. Increasing the batch size
-with this option may further improve write performance, at the cost
-of longer sort times. Also, temporary space will be needed to store
-the overview batches. At a rough estimate, about 300 * \fIcount\fR bytes
-of temporary space will be required (not counting temp files created
-by \fIsort\fR\|(1)). See the description of the \fB\-T\fR option for how to
-specify the temporary storage location. This option has no effect
-with \f(CW\*(C`buffindexed\*(C'\fR, because \f(CW\*(C`buffindexed\*(C'\fR does not need sorted
-overview and no batching is done.
-.IP "\fB\-s\fR \fIsize\fR" 4
-.IX Item "-s size"
-Size the history database for approximately \fIsize\fR pairs. Accurately
-specifying the size is an optimization that will create a more
-efficient database. (The size should be the estimated eventual size
-of the \fIhistory\fR file, typically the size of the old file, in lines.)
-.IP "\fB\-O\fR" 4
-.IX Item "-O"
-Create the overview database as well as the history file. Overview
-information is only required if the server supports readers; it is not
-needed for a transit-only server (see \fIenableoverview\fR in \fIinn.conf\fR\|(5)).
-If you are using the \f(CW\*(C`buffindexed\*(C'\fR overview storage method, erase all of
-your overview buffers before running \fBmakehistory\fR with \fB\-O\fR.
-.IP "\fB\-T\fR \fItmpdir\fR" 4
-.IX Item "-T tmpdir"
-If \fB\-O\fR is given, \fBmakehistory\fR needs a location to write temporary
-overview data. By default, it uses \fIpathtmp\fR, set in \fIinn.conf\fR, but if
-this option is given, the provided \fItmpdir\fR is used instead. This is
-also used for temporary files created by \fIsort\fR\|(1) (which is invoked in the
-process of writing overview information since sorted overview information
-writes faster). By default, sort usually uses your system temporary
-directory; see the \fIsort\fR\|(1) man page on your system to be sure.
-.IP "\fB\-x\fR" 4
-.IX Item "-x"
-If this option is given, \fBmakehistory\fR won't write out history file
-entries. This is useful mostly for building overview without generating
-a new history file.
-.SH "EXAMPLES"
-.IX Header "EXAMPLES"
-Here's a typical example of rebuilding the entire history and overview
-database, removing broken articles in the news spool. This uses the
-default temporary file locations and should be done while innd isn't
-running (or is throttled).
-.PP
-.Vb 1
-\& makehistory \-b \-f history.n \-O \-l 30000 \-I
-.Ve
-.PP
-This will rebuild the overview (if using \f(CW\*(C`buffindexed\*(C'\fR, erase the
-existing overview buffers before running this command) and leave a new
-history file as \f(CW\*(C`history.n\*(C'\fR in \fIpathdb\fR. To preserve all of the history
-entries from the old history file that correspond to rejected articles or
-expired articles, follow the above command with:
-.PP
-.Vb 2
-\& cd /usr/local/news/db
-\& awk 'NF == 2 { print }' < history >> history.n
-.Ve
-.PP
-(replacing the path with your \fIpathdb\fR, if it isn't the default). Then
-look over the new history file for problems and run:
-.PP
-.Vb 1
-\& makedbz \-s `wc \-l < history` \-f history.n
-.Ve
-.PP
-Then rename all of the files matching \f(CW\*(C`history.n.*\*(C'\fR to \f(CW\*(C`history.*\*(C'\fR,
-replacing the current history database and indexes. After that, it's safe
-to unthrottle innd.
-.PP
-For a simpler example:
-.PP
-.Vb 1
-\& makehistory \-b \-f history.n \-I \-O
-.Ve
-.PP
-will scan the spool, removing broken articles and generating history and
-overview entries for articles missing from history.
-.PP
-To just rebuild overview:
-.PP
-.Vb 1
-\& makehistory \-O \-x \-F
-.Ve
