RE: Problem recover replica

Hello Bron,

I've apply the patch on cyrus 2.4.13 succesfully and now I can fetch "rfc822.sha1" and "rfc822.filesize":

. fetch 1:* rfc822.sha1
* 1 FETCH (RFC822.SHA1 284c8e2602d2094609aefb31c64622dbcc8a59cb)
* 2 FETCH (RFC822.SHA1 40d4f8a1a1c214385d875181c7e950ea04571855)
* 3 FETCH (RFC822.SHA1 756b897109ba58dc78c451ffa1ba6837ec17a391)

. fetch 1:* rfc822.filesize
* 1 FETCH (RFC822.FILESIZE 1402)
* 2 FETCH (RFC822.FILESIZE 1399)
* 3 FETCH (RFC822.FILESIZE 2097759)

But I have some doubts about it. Fetch sha1 takes too much, I have 1500 mail (around 3GB of data) in this account and it take over 20 seconds to do it:
real    0m20.288s
user    0m0.380s
sys     0m0.014s

On the other hand fetch filesize takes 0,4 secs:
real    0m0.401s
user    0m0.369s
sys     0m0.022s

I thought that sha1 was already the GUID field and fetch them would be really fast, but it isn't. have I made something wrong? My perl code is the same in both "fetch":

my $s1Size = $IMAPs1->fetch('1:*', 'rfc822.filesize');

Finally, I attach the patch code for 2.4.13. As you said I had to made some "minor" changes (some compile error due to some missing object) and find the correct lines to apply it.

Thanks  & Regards.
