Description

Trying to rebuild the index, just after install the latest rev, with the new parameters  --mode=usenewindex  and  --mode=buildnewindex . The faster, apache is stopped, with  --mode=usenewindex  fails with the following error message. the slower works well.

Steps to reproduce

1. try to rebuild the index

Example

using this commandline:

sudo moin --config-dir=/var/www/moinmoin/config --wiki-url=https://my.wiki.ch index build --mode=usenewindex

using a farmwiki with this xapian config stuff:

    xapian_search = True
    xapian_index_dir = '/var/www/moinmoin/index'
    xapian_stemming = True
    xapian_index_history = False
    search_results_per_page = 30

Component selection

• xapian index rebuild

Workaround

• only use the slower rebuild with  --mode=buildnewindex .

I will now delete the index and try to add a new one, and after that I will test if buildnewindex still fails. While doing this now receive some other wired error like:  ERROR MoinMoin.macro:131 Macro FullSearchCached (page: 'KategoriaKategoria') raised an exception . But will fill a separate bug report.

• even after add a new index, rebuild with the "faster" methode is not possible -- MarcelHäfner 2009-12-13 10:45:20

Discussion

I'm not sure now if "rebuild" is still valid or only the new parameter should be used. So maybe the documentation should also be updated, I found here some "outdated" references:

• http://master19.moinmo.in/HelpOnXapian

• http://master19.moinmo.in/HelpOnMoinCommand#index-build

• http://hg.moinmo.in/moin/1.9/file/4a406029ad23/wiki/config/more_samples/xapian_wikiconfig_snippet#l10

Well, obviously here is some confusion, so let me add some infos, please review bug report after considering them:

• "rebuild" still works, but uses a similarly "unsafe" way of killing the old index before placing the new index into place as it did before in moin < 1.9

  • the time span where there is no valid index is much shorter than for moin < 1.9, though

• first use "buildnewindex" to build a new index, then "usenewindex" to use that freshly built index

Thanks for your explanation, everything works now!
