[#ZBX-9195] When receiving data of ZBX_NOTSUPPORTED, Proxy sets invalid value to lastlogsize and mtime.

Comment by Aleksandrs Saveljevs [ 2015 Jan 08 ]

Note that ~~ZBXNEXT-444~~ is meant to address a related problem in trunk.

Comment by Aleksandrs Saveljevs [ 2015 Jan 09 ]

Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-9195 (based on 2.0) by applying the suggested patch.

Comment by Aleksandrs Saveljevs [ 2015 Jan 09 ]

Upon deeper investigation it turned out that this problem is independent from ~~ZBXNEXT-444~~ and should be fixed separately under this issue.

(1) Please take a look at my changes in r51519.

asaveljevs Logic looks good, but that commit introduced some extra whitespace. Fixed that in r51521, please take a look. RESOLVED.

Fixed in pre-2.0.15 r51524, pre-2.2.9 r51525, pre-2.4.4 r51526, and pre-2.5.0 (trunk) r51527.

using log4j, was subjected to the output of a large amount of log.
mtime is the same but, size is different.
Getting mtime and size, not synchronized?
