We can now link even smaller Python binaries. For example, the hello.com program in the Python build directory is a compiled linked executable of hello.py which just prints hello world. Using decentralized sections, we can make that binary 1.9mb in size (noting that python.com is 6.3 megs!) This works for nontrivial programs too. For example, say we want an APE binary that's equivalent to python.com -m http.server. Our makefile now builds such a binary using the new launcher and it's only 3.2mb in size since Python sources get turned into ELF objects, which tell our linker that we need things like native hashing algorithm code.

If the argument is a mutable buffer and the mutable_flag argument is false,

the buffer. The length of the arg buffer in this case is not allowed to

A wrapper around the fcntl() locking calls.
|
|
|
|
`fd` is the file descriptor of the file to lock or unlock, and operation is one
|
|
of the following values:
|
|
|
|
LOCK_UN - unlock
|
|
LOCK_SH - acquire a shared lock
|
|
LOCK_EX - acquire an exclusive lock
|
|
|
|
When operation is LOCK_SH or LOCK_EX, it can also be bitwise ORed with
|
|
LOCK_NB to avoid blocking on lock acquisition. If LOCK_NB is used and the
|
|
lock cannot be acquired, an OSError will be raised and the exception will
|
|
have an errno attribute set to EACCES or EAGAIN (depending on the operating
|
|
system -- for portability, check for either value).
|
|
|
|
`len` is the number of bytes to lock, with the default meaning to lock to
|
|
EOF. `start` is the byte offset, relative to `whence`, to that the lock
|
|
starts. `whence` is as with fileobj.seek(), specifically:
|
|
|
|
0 - relative to the start of the file (SEEK_SET)
|
|
1 - relative to the current buffer position (SEEK_CUR)
|
|
2 - relative to the end of the file (SEEK_END)
