While adding new tests to gdb.base/commands.exp, I noticed that the
file includes a bunch of individual testcases split into their own
procedures, and that none have ever been adjusted to use
with_test_prefix. Instead, each gdb_test/gdb_test_multiple/etc
invocation takes care of including the procedure name in the test
message, in order to make sure test messages are unique.
Simon convinced me that using the procedure name as prefix is not that
bad of an idea:
https://sourceware.org/ml/gdb-patches/2016-10/msg00020.html
This commit adds an IMO simpler alternative to
with_test_prefix_procname added by that patch -- a new
"proc_with_prefix" convenience proc that is meant to be used in place
of "proc", and then uses it in commands.exp. Procedures defined with
this automatically run their bodies under with_test_prefix $proc_name.

This removes dead code in tui_alloc_source_buffer for handling a NULL
return value from xmalloc.
gdb/ChangeLog:
* tui/tui-winsource.c (tui_alloc_source_buffer): Remove
failed-xmalloc handling.
The logic for allocating a TUI source window's content buffer allocates
two more lines than needed, because it does not reduce the window height
by the highlight box's overhead. However, it does reduce the line width
accordingly. This patch makes the height and width calculation
consistent and improves the comment.
gdb/ChangeLog:
* tui/tui-winsource.c (tui_alloc_source_buffer): Subtract
highlight box's overhead when calculating the content height.
The code that fills the TUI disassembly window content first calculates
the maximum full length of a displayed disassembly line. This
calculation typically yields the wrong result. The result is too large,
so the bug does not cause any run-time failures, but unnecessary
confusion for the reader. This patch fixes the calculation.
gdb/ChangeLog:
* tui/tui-disasm.c (tui_set_disassem_content): Fix calculation of
the longest disassembly line's length.
A user reported a GDB crash with TUI when trying to debug a function
with a long demangled C++ method name. It turned out that the logic for
displaying the TUI disassembly window has a bug that can cause a buffer
overrun, possibly overwriting GDB-internal data structures. In
particular, the logic performs an unguarded strcpy.
Another (harmless) bug in tui_alloc_source_buffer causes the buffer to
be two lines longer than needed. This may have made the crash appear
less frequently.
gdb/ChangeLog:
* tui/tui-disasm.c (tui_set_disassem_content): Fix line buffer
overrun due to unchecked strcpy.
gdb/testsuite/ChangeLog:
* gdb.base/tui-layout.c: New file.
* gdb.base/tui-layout.exp: Use tui-layout.c, to ensure that the

While writing a Python frame filter, I found a few bugs in the current

* One spot converts a Python long to a CORE_ADDR using PyLong_AsLong.
However, this can fail on overflow. I changed this to use
get_addr_from_python.
* Another spot is doing the same but with PyLong_AsUnsignedLongLong; I
changed this as well just for consistency.
* Converting line numbers can print "-1" if conversion from long
fails. This isn't fatal but just a bit ugly.

didn't seem important enough to bother with.
