step 3a — 标准库: tools/py_embed/make_stdlib_zip.py packs the vendored Lib/ into <build>/python27.zip (397 modules, 6876547 bytes, ZIP_STORED — the zlib module is trimmed out of our CPython, so zipimport cannot inflate). The mtpython_stdlib target builds it; py_embed_test and the launcher test both run against it. platform/ScriptLib/PythonHost sets the embedding flags before Py_Initialize and, after it, puts the zip on sys.path and re-registers encodings.search_function with codecs — 2.7 builds the codec registry once, at startup, so replacing sys.path afterwards needs it back. step 3b — pack 模块: UserInterface/PythonPackModule.cpp copied verbatim; packExist/packGet/ initpack read root/ and uiscript/ through CEterPackManager, i.e. through asset_io. The CHINA_CRYPT_KEY block in that unit is CAccountConnector's and is kept #if 0 until the login slice (2V1). UserInterface/StdAfx.h is a documented partial mirror — the original is the whole client's PCH. The launcher test now runs initpack() as RunMainScript does (its first line), reads system.py / uiscript / locale text back out of the packs, and confirms cp1252 decoding works off the zip. system.py still stops at "No module named app" — the C++ modules are the 2V0 slice. gates: port_map.py check 0 errors · key leak check 8/8 none · macOS ctest 27/27 · android + ios port_platform compile clean.

"""Pack the vendored CPython 2.7.18 Lib/ into the python27.zip the host puts on sys.path.

|
|
make_stdlib_zip.py <Lib dir> <out.zip>
|
|
|
|
40250 shipped a real python27 installation, so `import encodings` found Lib/ through the
|
|
interpreter's prefix. The embedded interpreter has no prefix (Py_FrozenFlag, no site), so the host
|
|
supplies the stdlib as this one file — the arrangement validated on the device by
|
|
tools/py_embed_android/build-and-run.sh (PORT-PLAN 批次 2P step 3).
|
|
|
|
Entries are STORED, never deflated: the zlib module is not in the vendored Modules/ (see
|
|
docs/THIRD-PARTY.md), so zipimport could not inflate them. Only .py goes in; zipimport reads
|
|
source as happily as bytecode, and .pyc would pin the magic number to the build host's interpreter.
|
|
Written deterministically (sorted, fixed timestamp) so the file's sha256 identifies its contents —
|
|
3c checks that hash when staging the zip into a mobile sandbox.
