Hello, I have a rather large (~400MB) INBOX file in mbox format. When using deliver, it complains in the logs: Dec 2 16:47:13 petole deliver(niko): write() failed with mbox file /home/niko/mail/INBOX: File too large I do not see anything related in the configuration. And ulimit shows nothing special: $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d)

Hi all, I plan to run a dovecot IMAPS and POPS service on our network. We handle about 3 000 mailboxes. I thought first buying a topnotch server (8 cores and 16 Go RAM) with equalogic iSCSI SAN SAS 15K for storage backend. On second though (and after a comprhensive read of dovecot features), I saw in http://wiki.dovecot.org/MailLocation that index files can be created on a separete local

Hello. I am currently testing dovecot (0.99.10.8, Debian woody from backports), with the maildir storage. I have noticed that when I use the mailutil tool from uw-imap distribution to transfer my IMAP mailboxes from our current server (uw-imap, mbx format) to the dovecot one, the mails arrival time are apparently lost. I can see this in Pine, using the Arrival sort: the mailboxes on the

Hello, On my home server (Debian etch, custom 2.6.28.2 kernel), I am using ext3 for both root and /home filesystems, with barriers enabled to prevent corruption caused by my PATA disk write cache. Looking for a better performance, I have also set the commit=nr option as described in linux-2.6.28.2/Documentation/filesystems/ext3.txt, so that I now have: niko at petole:~$ mount -t ext3

Hi Niko, Do you mean branch prediction, i.e. __builtin_expect [1]? Many compilers support it, I think clang (LLVM's C/C++ frontend) is among them. - D.

Hello- I have set up Dovecot before and feel fairly comfortable with it but am having some issues with a new setup and have not been able to find a solution via Google or the list archives. I use offlineiimap to sync an IMAP account with an email provider. After the sync is complete, my ~/Maildir is set up with a folder called INBOX (with cur,new,tmp inside) and all my other folders set up at

I tried it on a simple file test.c (as you did) but actually clang does not show me any output. In addition I tried to set the CFLAGS specifying the -mllvm -time-passes options. However I still have anything about the time passes informations in the output and I also get this warning during the build with make:clang: warning: argument unused during compilation: '-mllvm -time-passes'Maybe

Hi ALL... I want to know if the files in /Maildir/cur & /Maildir/.Sent are modified by dovecot. I have a script which calculates the age of the mail files. I think that if they are continuously modified by dovecot I won't be able to calculate the age of the files. Can Anyone plz advise on this.... Thanks CoolAtt

To use options like "-time-passes" and "-stats" you need to prefix them with "-mllvm": clang -mllvm -time-passes -O3 test.c -o /dev/null Note that I believe you need asserts enabled or some other build configuration for this to work, the timing code is disabled in fully release builds IIRC. Hope this helps! ~Will On Thu, Sep 12, 2013 at 11:50 AM, Niko Zarzani

Hi all,Is there any way to tell LLVM some additional information about the variables in the code in order to make better optimization?For example, if my function has a certain precondition (such as x>0) then it will be possible to better optimize the code given that information (which the compiler does not know).I am new in this field and I don't know if there are ways to tell the compiler

Hello, I have a setup where there are multiple maildir users, one of them being the pop/imap server itself, the others are for example a maildir capable webmail and message replication. I would like to evaluate Dovecot, but I wonder how would its binary indexes and logs fit into this picture. After running through http://wiki.dovecot.org/IndexFiles I'm not sure how well would Dovecot

This compiler does not have mem-SSA, as far as I know, only few pass can propagate value along memory. You need to promote those local variable into register first before sccp is invoked. e.g1. opt a.ll -basicaa -gvn -sccp -S eg.2. opt a.ll -sroa -sccp -S On 4/16/13 12:37 PM, Niko Zarzani wrote: > Hi all, > > I am trying to see how single llvm optimizations work by running them

Hello, I read in the wiki (http://wiki.dovecot.org/MailboxFormat/mbox) about "From Escaping": "Dovecot doesn't currently do this escaping however. Instead it prevents this confusion by adding Content-Length headers so it knows later where the next message begins. Dovecot doesn't either remove the '>' characters before sending the data to clients. Both of these

Hi all, I was interested in knowing which of the passes spends the most of the time compiling the dns server BIND.With the -CC option I selected clang as my compiler and, as I was expecting, the compilation gave me no problems.Now I have a question, is there any way to set an option similiar to "-time-passes" to clang in order to get those information I was interested in?Or do you think

I am having a lot of troubles setting up an rsync daemon that works properly. I've inspected the Faq-o-matic and as much of the past archives as I can stand, but I can't seem to get any of the solutions suggested there to work. I'm having two problems. First, I can't get password authentication to work. I have ensured that the password file is only readable by root, and that

Hi All. I want to know how filenames are changed by dovecot e,g more details on how it renames the files when a mail is read. For read mails i found that it appends an S. 1264579250.P22376Q0M765148.ecs,S=1161:2 1264579250.P22376Q0M765148.ecs,S=1161:2,S Want to know if other modifications done in file names in INBOX & in SENT (maildir/.Sent/cur) Thanks CoolAtt

Ok looks like r207606 regressed this. CC'ing Niko. Niko, please see the messages below. This is on openSUSE 13.1 both on i586 and x86-64. Reverting r207606 fixes the second stage bootstrap.
