ztk/zopeapp的ztfy调度程序包
ztfy.scheduler的Python项目详细描述
内容
What is ztfy.scheduler ?
scheduler是那些需要构建可在内部运行的计划任务的基础包 基于ztk/zopeapp的环境（需要zeo！）。这些任务可以安排：
- on a cron-style base,
- at a given date/time (like the “at” command)
- or at a given interval.
调度是通过apscheduler（http://packages.python.org/APScheduler/）包完成的，并且 因此，所有这些类型的任务都可以使用相同的设置进行调度。但是任务管理 通过一个简单的web界面生成，运行历史记录的任务存储在zodb中。
在应用程序启动时，调度程序在专用的zeromq进程中运行，该进程还用于 处理任务设置和计划程序作业之间的同步。
任务日志可以在zodb中存储可变的持续时间（基于多次迭代）。 这些日志报告也可以通过邮件、每次运行或仅在检测到错误时发送。

0.4.9
- updated french translation
0.4.8
- added tasks attributes relatives to empty reports handling
0.4.7
- use “tztime” function in history sorting
0.4.6
- added one second before checking ZMQ processes startup
0.4.5
- remove ZTFY.security resources dependencies
0.4.4
- convert roles edit forms to dialogs
0.4.3
- register ZMQ scheduler process exit callback function
0.4.2
- added system command execution task (local, or remote throught SSH)
- added option to execute a task immediately on user’s request
0.4.1
- removed title from jobs list template
0.4.0
- complete package refactoring, with tasks and scheduler jobs synchronization based on a dedicated ZeroMQ process
0.3.4
- changed package source layout
0.3.3
- implement ztfy.security ILocalRoleManager interface
0.3.2
- start and stop scheduler when scheduler utility is registered or unregistered, instead of when it’s added or removed
- remove scheduler from schedulers handler when scheduler is stopped
0.3.1
- update ShelveJobStore to take care of specific file systems configurations, because sometimes shelve modification time is not updated when “sync()” is called. From now on jobs configuration timestamp is stored in shelve and a blocking file lock is used to prevent concurrent modifications in it. At least it seems to work on Linux, any feedback concerning other OS is still welcome…
0.3.0
- refactoring to follow last releases of ztfy.skin and ztfy.jqueryui packages
- redefined interfaces so that tasks scheduling mode (cron-style, interval-style…) can be defined on a per-task basis and is not bound to the task class; new scheduling modes can also be added via registered utilities
- store tasks execution log in tasks history
- add an “URL getter” task, which can be used to call a remote “management” URL on periodic basis
- add username/password/realm to ZEO connections
- modify ZODB packer task to be able to pack another remote database instead of only those to which scheduler is defined
- improved handling of transactions and conflict errors
0.2.2
- changed ISite package import
0.2.1
- updated database automatic upgrade code
0.2
- migrated to ZTK-1.1
- integrated ZODBPackerTask (moved from ztfy.blog package)
0.1
- initial release
