Can't open Xapian database on redmine 4.1.1

Environment

OS: Ubuntu 20.04.1 LTS Linux redmine 5.4.0-48-generic 52-Ubuntu SMP Thu Sep 10 10:58:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Redmine Environment: Redmine version 4.1.1.stable Ruby version 2.6.6-p146 (2020-03-31) [x86_64-linux] Rails version 5.2.4.2 Environment production Database adapter Mysql2 Mailer queue ActiveJob::QueueAdapters::AsyncAdapter Mailer delivery smtp SCM: Subversion 1.13.0 Git 2.25.1 Filesystem

Ruby installed by rbenv. Xapian-core-1.4.17 Xapian-bindings-1.4.17 and Xapian-omega-1.4.17 compiled from source to binding to ruby which controlled by rbenv.

XAPIAN_CJK_NGRAM=true ruby plugins/redmine_xapian/extra/xapian_indexer.rb -fxv

This command seems normal and no error reported.

When I search on redmine, the $redmine/log/production.log shows

Current user: admin (id=1) Can't open Xapian database /opt/redmine-4.1.1/file_index/repodb - #<IOError: DatabaseOpeningError: Couldn't stat '/opt/redmine-4.1.1/file_index/repodb' (No such file or directory)> Rendering plugins/redmine_xapian/app/views/search/index.html.erb within layouts/base Rendered plugins/redmine_dmsf/app/views/search/_container.html.erb (0.6ms) Rendered plugins/redmine_xapian/app/views/search/index.html.erb within layouts/base (7.5ms) Completed 200 OK in 59ms (Views: 19.7ms | ActiveRecord: 9.3ms)

ls -ld $redmine/file_index/* 

output:

rwxrwxr-x 2 adminuser adminuser 4096 Sep 22 14:36 /opt/redmine-4.1.1/file_index/english Indeed no repodb.

Questions:

1. how to resolve the repodb issue?
2. I install redmine_dmsf and redmine_xapian, it seems I need to set crontab for them separately. Right?

• -f parameter means that you want to index just files.
• -r parameter means that you want to index files and repositories.
• If you want to index both files and repositories just omit both parameters.
• If you want to index just files and not to see the error in the log, call the indexing with -r just once, the repository index will be created and no more errors will be reported.
• Indexing of Files and DMS are two independent jobs. Also folders and indexes for both modules shall be independent/separated.

OK. Thanks!

This notice means there is no repositories on my redmine instance ? Can't open Xapian database /opt/redmine-4.1.1/file_index/repodb - #<IOError: DatabaseOpeningError: Couldn't detect type of database>

Thanks for your explain.

Yes, if you have no repositories, or the repositories don't contain index-able files, just empty repodb folder is created but without any database. Correctly created database should looks like follows.

$ ls file_index/repodb/
docdata.glass  flintlock  iamglass  position.glass  postlist.glass  termlist.glass
