...global import state. The PEP also proposes inclusion of a GlobalImportEngine subclass and a globally accessible instance of that class, which "writes through" to the process global state. This provides a backwards compatible bridge between the proposed encapsulated API and the legacy process global state, and allows straightforward support for related state updates (e.g. selectively invalidating path cache entries when sys.path is modified). PEP Withdrawal The import system has seen substantia...
...global namespace is not modified in strange ways at runtime. They would add overhead for modules that did unusual things with global names, but this is an uncommon practice and probably one worth discouraging. It may be desirable to disable dynamic additions to the global namespace in some future version of Python. If so, the new implementation could provide warnings. Related PEPs PEP 266, Optimizing Global Variable/Attribute Access, proposes a different mechanism for optimizing access to gl...
...globals and reason about them. Tools/c-analyzer/cpython/globals-to-fix.tsv - the list of remaining globals Tools/c-analyzer/c-analyzer.py * analyze - identify all the globals * check - fail if there are any unsupported globals that aren't ignored Tools/c-analyzer/table-file.py - summarize the known globals Also, the check for unsupported globals is incorporated into CI so that no new globals are accidentally added. Global Objects Global objects that are safe to be shared (without a GIL) betw...

...global version tag is reset to 0. See Method cache (issue #1685986) and Armin's method cache optimization updated for Python 2.6 (issue #1700288). Globals / builtins cache In 2010, Antoine Pitrou proposed a Globals / builtins cache (issue #10401) which adds a private ma_version field to the PyDictObject structure (dict type), the field has the C type Py_ssize_t. The patch adds a "global and builtin cache" to functions and frames, and changes LOAD_GLOBAL and STORE_GLOBAL instructions to use the...

...global statement occurs within a block, all uses of the name specified in the statement refer to the binding of that name in the top-level namespace. Names are resolved in the top-level namespace by searching the global namespace, i.e. the namespace of the module containing the code block, and in the builtin namespace, i.e. the namespace of the __builtin__ module. The global namespace is searched first. If the name is not found there, the builtin namespace is searched. The global statement m...
...global expressions, untyped global expressions, and type aliases. This avoids the existence of assignments that break type checking when an annotation is added, and avoids classifying the nature of the assignment based on the type of the value. Implicit syntax (pre-existing): x = 1 # untyped global expression x: int = 1 # typed global expression x = int # type alias x: Type[int] = int # typed global expression Explicit syntax: x = 1 # untyped global expression x: int = 1 # typed global...
...GLOBAL opcodes account for over 7% of all instructions executed by the Python virtual machine. This can be a very expensive instruction, at least relative to a LOAD_FAST instruction, which is a simple array index and requires no extra function calls by the virtual machine. I believe many LOAD_GLOBAL instructions and LOAD_GLOBAL/LOAD_ATTR pairs could be converted to LOAD_FAST instructions. Code that uses global variables heavily often resorts to various tricks to avoid global variable and attri...
...globals aren't a celldict, and hence func_cells is NULL. In that case, the code object's co_globals is indexed with <i> to find the name of the corresponding global and this name is used to index the function's globals dict. Additional Ideas Never make func_cell a NULL pointer; instead, make up an array of empty cells, so that LOAD_GLOBAL_CELL can index func_cells without a NULL check. Make c.cellptr equal to c when a cell is created, so that LOAD_GLOBAL_CELL can always dereference c....
