* Fix some issues for GDB < 9.x
* GDB < 9.x doesn't have `gdb.lookup_static_symbol`
* GDB < 9.x doesn't have `gdb.PARAM_ZUINTEGER_UNLIMITED`
* Better error handling for the heap commands
* Inform users to `set exception-* on` when they encounter some error during using some heap commands
* Bug fix for heap region finding of `HeuristicHeap`
* Before this commit, `get_heap_boundaries()` of `HeuristicHeap` will always return the page whose name is `[heap]`, this won't work for multithreaded cases and won't work if the heap region of the main thread is not `[heap]` (e.g., when using QEMU, sometimes the name of heap region is something like: `[anon_deadbeaf]`)
* Fallback to `gdb.lookup_symbol` if we do not have `gdb.lookup_static_symbol`
* Add more features for `pwndbg.gdblib.config`
* Support all parameter-class
* Use `get_show_string` to render better output when using `show <param>`
* Show more information when using `help set <param>` and `help show <param>` if we create a config with `help_docstring` parameter.
Some examples of the updates included in this commit:
1. `gdb.PARAM_AUTO_BOOLEAN` with `help_docstring`
In Python script:
```
pwndbg.gdblib.config.add_param(
"test",
None,
"test",
"on == AAAA\noff == BBBB\nauto == CCCC",
gdb.PARAM_AUTO_BOOLEAN,
scope="test",
)
```
In GDB:
```
pwndbg> show test
The current value of 'test' is 'auto'
pwndbg> set test on
Set test to 'on'
pwndbg> set test off
Set test to 'off'
pwndbg> set test auto_with_typo
"on", "off" or "auto" expected.
pwndbg> show test
The current value of 'test' is 'off'
pwndbg> set test auto
Set test to 'auto'
pwndbg> show test
The current value of 'test' is 'auto'
pwndbg> help show test
Show test
on == AAAA
off == BBBB
auto == CCCC
pwndbg> help set test
Set test
on == AAAA
off == BBBB
auto == CCCC
```
2. `gdb.PARAM_AUTO_BOOLEAN` with `help_docstring`
In Python script:
```
pwndbg.gdblib.config.add_param(
"test",
"A",
"test",
"A == AAAA\nB == BBBB\nC == CCCC",
gdb.PARAM_ENUM,
["A", "B", "C"],
scope="test",
)
```
In GDB:
```
pwndbg> show test
The current value of 'test' is 'A'
pwndbg> set test B
Set test to 'B'
pwndbg> set test C
Set test to 'C'
pwndbg> set test D
Undefined item: "D".
pwndbg> show test
The current value of 'test' is 'C'
pwndbg> help show test
Show test
A == AAAA
B == BBBB
C == CCCC
pwndbg> help set test
Set test
A == AAAA
B == BBBB
C == CCCC
```
* Update the tests for gdblib parameter
* Use auto boolean for `safe-linking`
* Fix some comments
* Pass `help_docstring` directly
* Force callers of `add_param` to use keyword arguments
* Create `add_heap_param()` to avoid setting the scope of param everytime
* Add a header to the vmmap table
A simple header has been added to the output of vmmap which helps new users identify the columns.
* fix: lint
* fix: failing test
Adjust the length of expected vmmaps
* fix: tests again
* Fix parameter default values
Before this commit the created gdb.Parameter default values were not set
properly. Now, we set the object's .value field properly with the
provided default value.
* fix issue with set/show docstring
* fix lint
* fix lint
* fix lint
* fix parameter further...
* fix flake8 lint
* Increase CI timeout to 20 minutes
* Fixes: set context-sections '' and add more opts to set empty sections
The `validate_context_sections` function started to receive a string of
`"''"` after the changes in eabab31. Before those changes, it always
received an empty string (`""`).
I am not sure why this behavior changed in that commit, but the current
behavior resembles the native GDB behavior more. We can see this here on
a GDB native parameter:
```
(gdb) set exec-wrapper ''
(gdb) show exec-wrapper
The wrapper for running programs is "''".
```
And so we will keep this native behavior for our config variables for
now. But since this changed, I want to keep the old behavior of: `set
context-sections ''` working, and so this commit brings it.
Additionally, we also now allow setting empty context via multiple
values: empty string, empty quotations or double quotations and with
strings like `-` or `none`.
...and this commit comes with tests for this behavior so it will be
harder to introduce such issues anymore :)
