(1) On a 32-bit system agent fails when doing stat() of the log file in a process_log() function, which results in an item becoming NOTSUPPORTED:

Related issue: ZBX-3151

Successfully tested. Log monitoring is working for files over 2GB on 32-bit systems. Also confirm that this fixes vfs.file.size[] report for files over 2GB (was ZBX_UNSUPPORTED before).

(1) This enables general support for files larger than 2GB on Zabbix side (all components), I suggest this be documented as new 2.0 feature.

<richlv> documented in http://www.zabbix.com/documentation/2.0/manual/introduction/whatsnew200 -> RESOLVED

(2) Should be documented DB upgrade patches from 2.0.0rc4 to 2.0.0rc5 in the release notes.

IBM DB2:
ALTER TABLE items ALTER COLUMN lastlogsize SET DATA TYPE bigint
REORG TABLE items

MySQL:
ALTER TABLE items MODIFY lastlogsize bigint unsigned DEFAULT '0' NOT NULL;

Oracle:
ALTER TABLE items MODIFY lastlogsize number(20);

PostgreSQL:
ALTER TABLE items ALTER lastlogsize TYPE numeric(20);

<dimir> While at it, could next info also added?

When upgrading from 2.0.0rc2 to 2.0.0rc3, if proxy is used and proxy uses MySQL:
ALTER TABLE proxy_history MODIFY value longtext NOT NULL;

<Sasha> we supports incremental patches only from version 2.0.0rc4
<Sasha> CLOSED patches will be published in the release notes

Available in version pre-2.0.0 r27570.

Reopening because of regression. After this fix Zabbix will not compile on Solaris (SPARC) anymore.

(3) Disable large file support on 32-bit Solaris.

On a 32-bit Solaris large file support is incompatible with procfs and swapctl. There is a way to do that though by using transitional compilation environment but this has to wait at least till 2.0 is out. See lfcompile64(5) for details.

I removed the message on support of large files. The call of AC_SYS_LARGEFILE doesn't guarantee it.
