Compact databases and removing stale records at the same time
I'm trying to compact (or at least merge) multiple databases, while stripping search records which are no longer required. Backstory: I've inherited the Cyrus IMAPd xapian-based search code from Greg Banks when he left Opera. One of the unfinished parts was removing expunged emails from the search database. We moved from having a single search database to supporting multiple

Adding before / after blocks to every spec
Folks, I was wondering if someone would be able to help me out with a quandry. I''m trying to write an rspec plugin module for merb that will run all specs within an ActiveRecord (initially) database transaction - to give functionality similar to rails transactional fixtures. Here is the module: module Merb module Test module TransactionalSpecs def begin_transaction

goodbye QuartzBufferedTable
I've finally managed to sort out the problems with my patch to eliminate QuartzBufferedTable and checked it in. I'm currently building a large database to test this. The rate was quite a bit faster initially but after around 200K documents it has settled down to being very slightly faster than before. Even if the eventual rate is much the same, this at least improves the time taken to

sorting large msets
Hello, is there a way to optimize sorting by certain values for queries which return a huge amount of results? For example, I just want a simple query that gives me the 200 most recent emails out of millions. The elapsed time for get_mset increases as the number of documents ($n * 2000) increases. I suppose I could store a pre-sorted set using SQLite or similar. Thanks in advance for any

[PATCH] Btrfs: pass lockdep rwsem metadata to async commit transaction
The freeze rwsem is taken by sb_start_intwrite() and dropped during the commit_ or end_transaction(). In the async case, that happens in a worker thread. Tell lockdep the calling thread is releasing ownership of the rwsem and the async thread is picking it up. Josef and I worked out a more complicated solution that made the async commit thread join and potentially get a later transaction, but

Implemented test coverage for using TradWeight with an Rset
Hello guys. Olly had pointed out on IRC that there is no test for using the TradWeight scheme with a Rset and had directed me to the test coverage of the TradWeight scheme :- http://lcov.xapian.org/latest/weight/tradweight.cc.gcov.html I have added a test to api_anydb.cc which tests the TradWeight scheme using an Rset . I simply modified the rset2 test in api_anydb.cc so that the Mset is made

Problems with /bin/cat and flintlock?
Hi Guys, I'm working on some integration project with Ruby, Rack, Apache, Phusion Passenger and Xapian. I've been having intermittent issues with the flintlock code - it seems that the function FlintLock::lock is never returning and this is locking up the Ruby process. My guess is that Xapian is locking up in a system call and Ruby can't schedule its green threads. I've done

possible memory leak in ldb module while dbcheck on RODC
Hai Andrej, Oeps, Sorry, my mistake 4.6.x needs at least 1.1.29. But you can upgrade to 4.6.x ;-) Check again and if that problem then still exists, then i think you can better ask this one in the samba-technical list. Or if Rowland knows something more about this. One tip, wait untill tomorrow or the weekend, there wil be a new release due to the regression bug. There planning is to be

rails equivalent of autoflush
Hello, Is there an option in rails that will tell the action to output data to the browser immediately rather than waiting until it''s completely done. In the perl/mason world there is an autoflush command that does what I''m looking for. Thanks, Mark

regpatch writing to local registry hive with -F not working (registery-utils 4.0.0~alpha15~git20110124.dfsg1-2ubuntu1)
Hi, I was hoping I could modify a locally mounted registry hive using regpatch and a .reg file but the -F argument seems to have no function. (Strace shows it ignores it and just operates on /var/lib/samba/private/hklm.ldb) Below is output with debug on. rfm6 at ubuntuSSDx64:cp /mnt/xp/WINDOWS/system32/config/software /tmp/software rfm6 at ubuntuSSDx64:/tmp/config$ sudo regpatch -d=10 -F

[PATCH -v2 0/3] jbd2 scalability patches
This version fixes three bugs in the 2nd patch of this series that caused kernel BUG when the system was under race. We weren't accounting with t_oustanding_credits correctly, and there were race conditions caused by the fact the I had overlooked the fact that __jbd2_log_wait_for_space() and jbd2_get_transaction() requires j_state_lock to be write locked.

Running a perl script in a rails application
I have a perl script that will be executed in one of my controllers and will produce text output for a period of time. When I hit my rails app, the page doesn''t render until the perl script has fully completed running and then I''ll see all the output in one shot. I know with CGI I can just autoflush to see the output as it''s produced. Is there some similar functionality

avoiding spanning packets
Monty, I recently noticed half a patch in my libogg tree, and thought I'd forward it for discussion. I did this some time ago when were were talking about the long pages issue. The basic idea is to allow pages to grow up to 100% above the flush threshold if this allows us to end at a packet boundary. This reduces the frequency of pages with spanning packets which should be some assistance to
