2003-02-14 10:21:54 +00:00

< P > What has probably happened is that the dupefile has got corrupted in
some way. Simply delete the /spider/data/dupefile and restart the
cluster. It may take a little time to become fully functional but
should solve your problem.< / P >

< / H2 >
< P > This is now the way messages are handled for deletion in Spider. If you
look closely you will see a 'D' following the message number. This
message is marked for deletion and will be deleted in 2 days if nothing
further is done. Optionally you can use the command < EM > delete/expunge< / EM >
to delete it immediately.< / P >

2005-02-09 11:10:54 +00:00
< P > For normal CVS use you should only ever see the letters 'P', 'U' or '?'. The
letter 'P' means that the file has
changed in CVS and is more recent than the one that is currently on your system. You will also
see the letter '?', which means that
2005-02-08 23:21:33 +00:00
there is a file that you (or the system) has created that CVS doesn't know about and isn't
under its control. These are all normal and good.< / P >
< P > Sometimes you will see the letter 'U' next to a file. This means that it is a new file that you don't currently
have. This is also OK.< / P >
< P > However, if you see the letter 'C' or 'M', that means that CVS thinks that the file has
changed locally. For the letter 'C', it has changed sufficiently near to one or more
modifications which CVS wants to download to your system. For the 'M', CVS thinks that it
is OK to make the change (you may also see some messages about "merging revision 1.xx with 1.yy").
Neither of these things are good. Files that are under the control of CVS
must not be changed by sysops. It is the files that have the 'C' next to them that will show
2005-02-09 11:10:54 +00:00
the errors that you are complaining about and they will be things like:-< / P >
2005-02-08 23:21:33 +00:00
< P >
< BLOCKQUOTE > < CODE >
< PRE >
Syntax error near '< < < < ' at line 23
Syntax error near '===' at line 40
Syntax error near '>>>' at line 51
< / PRE >
< / CODE > < / BLOCKQUOTE >
< / P >
2005-02-09 11:10:54 +00:00
< P > You will not necessarily see all of the errors shown but you will get one or more sets of some
2005-02-08 23:21:33 +00:00
of them. The cure is simple: < / P >
< P >
< UL >
< LI > identify the file that is causing the problem. < / LI >
< LI > remove the file.< / LI >
< LI > run the cvs update again.< / LI >
< / UL >
< / P >
< P > You will see that file come back (with a letter 'U' next to it). That will be the correct
file as CVS thinks it should be. If you < EM > still< / EM > have a problem, then get onto the
dxspider-support mailing list.< / P >
< P > If all else fails (or you have several conflicts) you can safely remove the entire < CODE > /spider/perl< / CODE > and
< CODE > /spider/cmd< / CODE > directories and then run the cvs update. They will all be recreated in their pristine
condition.< / P >
< H2 > < A NAME = "ss2.11" > 2.11< / A > < A HREF = "spiderFAQ_en.html#toc2.11" > I have done a CVS update, restarted and it says that "fileX" is missing< / A >
< / H2 >
< P > The correct way to run cvs is:-< / P >
< P >
< BLOCKQUOTE > < CODE >
< PRE >
cd /spider
cvs -z3 update -d
< / PRE >
< / CODE > < / BLOCKQUOTE >
< / P >
2005-02-09 11:10:54 +00:00
< P > The '-d' is crucial. It makes sure that any new directories, that may contain new code,
2005-02-08 23:21:33 +00:00
are created and that new code downloaded. I have absolutely no idea why this is not the
default, seeing as CVS (in other circumstances) happily recurses its merry way down a
directory tree, but there you are.< / P >
< P > WinCVS and other graphical CVS frontends have a checkbox for the update screen called something
like "create sub-directories" (it may be hidden in some sub-screen - go look for it if it isn't
obvious). Make sure that this box is checked. If you can make this the
default setting in the program's setup screen then please do that. It will save you a lot
of pulled hair. < / P >
