similar to: Webmail architecture : questions about cache and storage backend

Hello, I found a posting on the mailing list from 2008 "Adding new storage backend to Dovecot" while searching for POP3 and IMAP servers, that allow to use a NoSQL backend rather than a traditional file system. The problem with traditional filesystems is, that they are very limited. You cannot easily extend it, even with RAID 10 all messages may be lost due to a RAID controller

Hi, I am trying to optimize an imap library and I am comparing with some existing webmail, for instance from roundcube I can log the imap commands with the following format : [11-Jan-2012 14:22:55 +0100]: [DBD1] S: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=DIGEST-MD5 AUTH=CRAM-MD5] Dovecot ready.

Hi Vincent, This is an LLVM issue, rather than a clang issue, so llvmdev is the appropriate mailing list for this report. Your fix looks semantically valid, but it would be cleaner to only create and destroy the pthread_rwlockattr_t if it is actually needed, rather than creating it, initialising it, not using it, and then destroying it on mingw (and, as the code currently stands, *BSD). The

David, Your fix sounds fine to me. Please apply. --Owen On Feb 14, 2010, at 6:30 AM, David Chisnall wrote: > Hi Vincent, > > This is an LLVM issue, rather than a clang issue, so llvmdev is the appropriate mailing list for this report. > > Your fix looks semantically valid, but it would be cleaner to only create and destroy the pthread_rwlockattr_t if it is actually needed,

Of course it'll be running as now. But user will need have installed MongoDB. Installation on linux with support of .deb packages is quite easy. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927 echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.2 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list sudo apt-get update sudo apt-get

Hi Elena, Thanks for pushing forward with this. I like the idea of using a NoSQL solution. My primary reservation is about adding the new NoSQL stuff as an extra backend. I think the current database backend and its use of SQLAlchemy is extremely complex and is in fact the most complex part of LNT. Adding something more (as opposed to *replacing* it) would just make this worse and make it more

Hi all, As we understood great changes will be done in LNT, so we are waiting to new LNT version and stopped our work in LNT. One more question about using test-suite separately with cmake. Cmake can only build all tests and generate lit tests. After that we can run LIT and get report which is not equal with report (simple) got with make. Cmake test-suite version has no features to run custom

Hi, Chris. Thank you for your answer about compile tests. As I understood during looking through code of compile tests they don’t use test suite at all. Am I right? There is lack of information and examples of running compile tests in LNT documentation. We understood that there are two groups of users: users using servers and collecting a lot of data and SQLite users, but these users as I think

Is there any support for NoSQL databases such as Cassandra (CQL) or MongoDB now or planned in the future for userdb and passdb lookups?

Hello All - I am trying to use RJSONIO to read in some JSON files. I was wondering if anyone could please comment on the level of complexity of the files it can be used to read, exports from or directly from NoSQL DBMS like MongoDB and such. Also, i understand that in reading the JSON file RJSONIO will automatically create the necessary structures. However I cannot seem to use to to read the

Hi, I am trying to move from dovecot-1.x to dovecot 2.1 but I have this error : Sep 23 16:04:13 lda: Error: userdb lookup: connect(/var/run/dovecot/auth-master) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /var/run/dovecot/auth-master, dir owned by 0:0 mode=0755) and I dont' manage to find information about how to translate this old configuration part:

Dear R users/developers, I am posting on behalf of a friend who is looking for R developers. The requirements are : - Available to work/re-locate to Bangalore, India - Over 5 - 6 years of solid R experience is essential - The ideal candidate should have worked on regression modeling and predictive models - Experience using Big Data technologies (like Hadoop)

I see these errors more often than I'd like from Dovecot-1.1.2 on Mac OS X 10.5.4 (names and numbers elided): Corrupted index cache file %s: Corrupted virtual size for uid=%d: %d ! = %d Corrupted index cache file %s: Broken virtual size for mail UID %d Corrupted index cache file %s: used_file_size too large How bad are these?

Now that I have a working kvm setup, I thought I'd finally try how Zimbra works. This is mainly some microbenchmarking, so it may not have much to do with actual performance in real life. Setup: - 1GB memory given to kvm (from host's 2GB) - Intel Core 2 6600 (kvm uses only one CPU) - CentOS 5 - 15GB qcow2 image on XFS filesystem - Zimbra 5.0 RC2 RHEL5 x86_64 - Dovecot latest hg,

I thought I'd try benchmarking with dbmail (v2.2.4) to see how much slower a SQL backend could actually be. Skip to bottom for the conclusions. Originally I ran the tests with the databases being in XFS filesystem. MySQL's performance was horrible. It went 3-7x faster with ext3.
