- Subject: [PATCH v4 6/6] Rename python function thread_from_thread_handle to thread_from_handle
- References: <20190404165854.17343-1-kevinb@redhat.com>
This renaming was done to stay consistent with the naming of the new
gdb.InferiorThread.handle method. I had initially named it "thread_handle"
but Tom Tromey suggested just "handle".
The old name (thread_from_thread_handle) still works, but is marked as
deprecated in comments in the code as well as in the documentation.
I have some code which uses these functions. I very much like the
brevity of the new names.
gdb/doc/ChangeLog:
* python.texi (Inferiors In Python): Rename
Inferior.thread_from_thread_handle to Inferior.thread_from_handle.
Add note about the former being deprecated.
gdb/ChangeLog:
* python/py-inferior.c (infpy_thread_from_thread_handle):
Adjust comments to reflect renaming of thread_from_thread_handle
to thread_from_handle. Adjust keywords. Fix type error message.
(inferior_object_methods): Add thread_from_handle. Retain
thread_from_thread_handle, but mark it as deprecated.
testsuite/ChangeLog:
* gdb.python/py-thrhandle.exp: Adjust tests to call
thread_from_handle instead of thread_from_thread_handle.
