When I run FlashPrint 3.6 or 3.7.1, it crashes right upon the start with the message error: 'Create opengl share context failed!' The same version works fine on Linux Ubuntu. Re: FlashPrint 3.6, 3.7.1 crash (opengl share failed) on Windows 10. Home City and County of Denver.

Pre-processing and Post-processing Methods¶
Data pre-processing and post-processing methods can be registered using the
pre_load
, post_load
, pre_dump
, and post_dump
decorators.There are now newer bugfix releases of Python 3.7 that supersede 3.7.1 and Python 3.8 is now the latest feature release of Python 3. Get the latest releases of 3.7.x and 3.8.x here. We plan to continue to provide bugfix releases for 3.7.x until mid 2020 and security fixes until mid 2023. Among the major new features in Python 3.7 are. I do not use this feature as GTD relies on lists of actions by context. Choosing which Next Action to do next depends on the context, and time and energy available. 3.7 Setting up your GTD File. I use one file to contain all my projects, tasks, agendas and someday/maybe lists. 3.7.1 File Header. 4.0 Context of the Organization 13 4.1 Understanding the Organization and its Context 13 4.1 4.4 4.2 Understanding the Needs & Expectations of Interested Parties 13-14 4.2 4.3 Determining the Scope of the QMS 14 4.3 4.4 Quality Management System & its Processes 14-16 4.4 5.0 Leadership 16.
Passing “many”¶

By default, pre- and post-processing methods receive one object/datum at a time, transparently handling the
many
parameter passed to the Schema
’s dump()
/load()
method at runtime.In cases where your pre- and post-processing methods needs to handle the input collection when processing multiple objects, add
pass_many=True
to the method decorators.Your method will then receive the input data (which may be a single datum or a collection, depending on the dump/load call).
Example: Enveloping¶
One common use case is to wrap data in a namespace upon serialization and unwrap the data during deserialization.
Raising Errors in Pre-/Post-processor Methods¶
Pre- and post-processing methods may raise a
ValidationError
. By default, errors will be stored on the '_schema'
key in the errors dictionary.If you want to store and error on a different key, pass the key name as the second argument to
ValidationError
.Pre-/Post-processor Invocation Order¶
In summary, the processing pipeline for deserialization is as follows:
@pre_load(pass_many=True)
methods@pre_load(pass_many=False)
methodsload(in_data,many)
(validation and deserialization)@post_load(pass_many=True)
methods@post_load(pass_many=False)
methods
The pipeline for serialization is similar, except that the
pass_many=True
processors are invoked after the pass_many=False
processors.@pre_dump(pass_many=False)
methods@pre_dump(pass_many=True)
methodsdump(obj,many)
(serialization)@post_dump(pass_many=False)
methods@post_dump(pass_many=True)
methods
Warning
Contexts 3.7.1 For Minecraft
You may register multiple processor methods on a Schema. Keep in mind, however, that the invocation order of decorated methods of the same type is not guaranteed. If you need to guarantee order of processing steps, you should put them in the same method.
