Fluentd v1.15.3 has been released

Hi users!

We have released v1.15.3 on 2022-11-02. ChangeLog is here.

In this release, we fixed several bugs.

Bug Fixes

out_file: Fix the multi-worker check with <worker N-M> directive

In the v1.15.1, we added a new feature to prevent write conflicts between multiple workers.

• #3808

However, this fix didn't work correctly with <worker N-M> directive.

• <worker N-M> directive

With this setting, the configuration check before starting the supervisor mistakenly determines that the setting of out_file is invalid and causes Fluentd to terminate.

In this release, we fixed this problem.

See #3942 for more information.

Fix log rotation on Windows

We can configure log rotation setting as follows.

• Log Rotation Setting

On Windows, the log files must be separated by each process.

NOTE: When --log-rotate-age is specified on Windows, log files are separated into log-supervisor-0.log, log-0.log, ..., log-N.log where N is generation - 1 due to the system limitation. Windows does not permit delete and rename files simultaneously owned by another process.

However, that log rotation setting in the system-directive didn't satisfy this and Fluentd outputed the logs of the supervisor process into the log file of the worker-0 process.

This could cause errors during log rotation.

In this release, we fixed this problem.

See #3939 for more information.

Support glob for !include directive in YAML config format

In the v1.15.0, we supported YAML config format.

• Config File Syntax (YAML)
• #3712

However, handling glob of !include directive was leaked.

In this release, we supported it.

See #3917 for more information.

Remove meaningless and unsecure oj options

In this release, we removed the following oj options.

• FLUENT_OJ_OPTION_MODE=object
• FLUENT_OJ_OPTION_MAX_NESTING

FLUENT_OJ_OPTION_MODE=object was unsecure, so we removed it.

• GHSA-fppq-mj76-fpj2

This option is not used unless a user explicitly sets the environmental variable, so almost all users do not need to care about this vulnerability.

FLUENT_OJ_OPTION_MAX_NESTING was not supported, so we removed it.

See #3929 for more information.

Fluentd v1.15.2 has been released

Hi users!

We have released v1.15.2. ChangeLog is here.

In this release, we fixed the problem that out_file's append mode with --daemon flag failed to flush the buffer.

Bug Fixes

out_file: Fix append mode with --daemon flag

In the previous version v1.15.1, we added a new feature to prevent write conflicts between multiple workers.

• #3808

However, this fix didn't work correctly with --daemon flag of Fluentd command.

• Command Line Option

With that flag, out_file in the append mode fails to flush the buffer. This is a critical bug for td-agent, because td-agent uses --daemon flag by default.

In this release, we fixed this problem.

See #3864 for more information.

Miscellaneous fixes

• Add a new system configuration enable_jit. #3857
• child_process: Plug file descriptor leak. #3844
• Drop win32-api gem to support Ruby 3.2. #3849, #3866

Enjoy logging!
