#177378 — logrotate - got compressed log

I have logrotate with config (excerpt)
--8<---------------cut here---------------start------------->8---
compress
delaycompress
dateext
mail root
compresscmd /usr/bin/xz
uncompresscmd /usr/bin/unxz
compressext .xz
compressoptions -9
tabooext +.dpkg-bak
minsize 1M
[...]
--8<---------------cut here---------------end--------------->8---

And since some days I started to receive *compressed* old syslog files
:( instead uncompressed ones. 

Nothing has happen in configuration.
The only change was logrotate upgrade, from 3.8.7 to 3.11.0
Can anyboty confirm that there is difference between these versions?

If you have the "compress" directive there you should expect to get
compressed logs.

I can't. As far as I can see you should expect compressed rotated
files with your config, both in 3.8.7 and 3.11.0.

Cheers,
Andy

Sorry, I did not write precisely.
I started to receive compressed old logs by *mail*.
So far, there were simple text in mail.

I understand, that old files on disk are compressed.

Presumably you should be emailed the file after rotation, when it has
been closed, i.e. the version you should get is <logfile>.1 which if
originating with rsyslog, should not be compressed. <logfile>.2 and
subsequent should be compressed.

After downgrade to 3.8.7-2 I got plain text in mails as expected. So it
is 3.11.0-0.1 issue.

I'm on 3.11.0 on sid, behaviour appears unchanged. Compression options
for rsyslog are compress and delaycompress, meaning that the open
logfile and the previous one are uncompressed, earlier ones are
compressed. I'm fairly sure this has been the Debian default for years.
