### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.
[end sys1]


GLib 2.x has two allocation API:

g_slice_alloc() / g_slice_free()

/ g_malloc() / g_free()

The former is a slab allocator that has the ability, through environment variables/configuration, to fall back to the latter; the latter is a proxy for the system allocator, but had the ability to be expose a stable API that could be replaced by any allocator, through a virtual functions table set before any GLib function was called.

Internally, GLib uses a hodge-podge of calls to g_slice_alloc and g_malloc , depending on the age of the code in question.

With the introduction of constructors to replace initialization functions, the vtable approach for g_malloc() has been deprecated and cannot be used any more—there is no way for any API call to replace the allocator implementation at compile time.

Similarly, with the introduction of the use of -Bsymbolic in our default linker flags, we cannot use LD_PRELOAD and weak symbols to replace malloc() and free() at run time.

Additionally, various programming languages that have bindings for GLib have their own custom allocators, which have been optimized for the language requirements; the intersection between the completely opaque GLib allocation mechanism can lead to memory fragmentation, and difficulties in accounting the memory pressure.

Finally, while system allocators have improved their performance envelope in the time between the introduction of GSlice and now, custom allocators have seen further development, and are routinely used in complex projects that have special requirements for memory allocations. Similarly to the integration with other languages, the memory allocation strategy of GLib makes it completely opaque to the developers of these projects, and prevents tooling from inspecting memory usage, fragmentation, and pressure.

With the push to deprecate and replace g_slice_* with the system allocator currently ongoing in issue #1079, GLib is going to have a single, non-overridable allocator API that wraps the system allocator.

WARNING: This is a strawman. It's meant to be discussed and changed, and it does not represent a final design. Changes should be constructive/iterative.

A new allocator API

The basic approach would be to create a new Allocator API that provided the following entry points:

gpointer g_allocator_alloc ( const GAllocator * allocator , gsize block_size , gsize n_blocks ); gpointer g_allocator_alloc0 ( const GAllocator * allocator , gsize block_size , gsize n_blocks ); gpointer g_allocator_aligned_alloc ( const GAllocator * allocator , gsize block_size , gsize n_blocks , gsize alignment ); void g_allocator_free ( const GAllocator * allocator , gpointer mem_block ); void g_allocator_aligned_free ( const GAllocator * allocator , gpointer mem_block ); void g_allocator_realloc ( const GAllocator * allocator , gpointer mem_block , gsize old_size , gsize new_size );

The GAllocator data structure is a pointer to the allocator vtable, which replicates the API above.

Usage

Allocators are kept in a simple, thread-local stack that can be pushed and popped at will:

void g_allocator_push ( const GAllocator * allocator ); void g_allocator_pop ( void ); const GAllocator * g_allocator_get_current ( void );

Every data structure used by GLib will keep a backpointer of the current allocator at construction time, and will call the appropriate free function when releasing the resources it has; this allows to keep track of the appropriate allocator at run time whenever a new one gets pushed.

GLib provides a default allocator wrapping the system one:

const GAllocator * g_allocator_get_system ( void );

Which is also the default allocator pushed when we enter in the GLib constructor.

Changes in GLib

All allocated types in GLib will need to keep a backpointer to the GAllocator , and must never call g_allocator_get_system() itself.

Changes in external code

Similar changes to GLib should be applied to external code.

Language bindings and applications would be able to set up a new GAllocator instance, and push it at initialization/load.

Prior art

Most of the current design is inspired to the custom allocators crate in Rust.
