* Added types to hexdump()'s parameters
* hexdump(): upgraded format strings to f-strings, while fixing the offset when data is empty
* hexdump(): offset is now correctly computed and updated accross repeated calls to hexdump.
This fixes two bugs:
1. Offset was increased by the number of lines displayed by the hexdump() command,
which was incorrect, as some lines may be compressed;
2. When dumping a number of bytes that is not divisible by the number of bytes per line,
offset would be incorrectly updated.

* Only look for readable address in retaddr command
* Rename stack.py to retaddr.py
* Add pwndbg.gdblib.stack.callstack and use it in retaddr
* Add callstack gdb test
* Add QEMU callstack test
* V1 - annotations for values of registers and memory to display result of instructions.
* Emulator telescope(), more x86 instructions
* Emulation change - keep track of before & after instruction execution. Telescope format correctly, read size taken into account
* Add config options to configure emulation and annotations, vmovaps alignment warning, string length in disasm telescope, cache previously annotated instructions
* Create PwndbgInstruction type for better typing and easier future development
* More consistent spacing, options to disable annotations, ADD instruction shows operands
* Rebase from dev
* Correctly go to .next address in disasm view (was incorrectly going to call targets)
* Precompute register str to reduce code duplication
* Correct telescope memory read width, bring target printing back to previous behavior when symbol can be resolved
* More consistent looking annotation spacing/padding, fixed edge case bugs with cached instructions
* Even cleaner padding
* Additional comments and debugging, ironed out last bugs
* debugging tight loops
* Cache fixed - nearpc only annotates what can be statically resolved
* lint and show instructions that cannot dereference
* Reapply btrace crash fix after rebase
* Less code duplication, implement XCHG and AND instructions, moved more methods from x86 subclass to superclass
* aarch64 set flags register in Unicorn correctly
* fix
* Don't recreate emulator regname->const map every time the emulator is instantiated
* Use emulation to set .next within enhancement
* Improve ret instruction target address setting
* Green checkmarks for jumps on all architectures
* Fixed .next and .target setting
* All architectures now have correct logic for determining .next and .target. Green checkmarks for taking conditional branches now appear for all architectures, added things to determine that type of branch being taken, and simplified printing by replacing symbol_addr with new field 'target_string'
* Instruction debug print fix
* Correct jump instruction checking
* Fixed target_string resolution
* Fix conditional jump check, also make default target resolution better
* target_const determined more accurately
* reverse iteration order of last change
* Pwndbg.condition is more retyped and more correct, make manual determinations of condition override the emulators (it can be incorrect in cases). Uncover why MIPS sometimes takes incorrect jumps in the emulator (delay slot)
* MIPS annotations work really good now. Jumps are correctly predicted (with green checkmarks). Implemented manual condition() function for MIPS. Only highlight the correct instance of instruction at PC when there are multiple in view (tight loops). Allow manual .condition to override emulator in determiningg .next.
* Additional debug info on instructions
* Print arch in instruction
* aarch64 branch fix
* aarch64 branch fix (real)
* lint
* Final changes - fixing .size error
* lint
* Add dev_dump_instruction command, add default memory read in resolve_used_value, update comments and remove .size from enhancedoperand as it only exists on x86
* More uniform spacing on annotations
* Various comments converted to docstrings, aarch64 enhancer created, post-rebase
* import aarch64
* Aarch64 mov, ldr, add, sub
* adrp
* ADR
* lint
* Fun with git rebase
* lint
* lint again after re-installing dependencies
* New caching strategy implemented to ensure no state caching when jumping large distances. Handled edge cases of user manually setting a register or memory, 'set regname=2'
* lint
* Fixed two regressions (nearpc shouldn't take jumps, even ones we know statically, and replace all constants in the assembly with symbols). Tweak tests to reflect new annotations
* lint
* one last test
* Fix chain format dereferencing for non-singleton lists, now correctly deferences and displays chains for future instructions when not emulating (dereference until pointer goes to writable memory)
* Add jumps-only setting to emulation (on, off, jumps-only), fixes to chain deferencing and enhancing
* Properly dereference memory before and after execution of instructions, adding a new before_value_resolved field (same for after). This also reduces code duplication.
* Debogusify the format()/telescoping dereferencing logic
* lint
* post-rebase fixes
* Fix case the breaks a test - don't attempt to read larger than ptrsize such as in SIMD instruction memory reads
* Typo in emulate setting
* Developer docs for annotations
* Fix case where emulator attempts to read and unpack very large, 16 byte+ wide values while telescoping
* Add a helper command to find valid one_gadget for current context
* Refactor the function for getting section address
* Rename the command to onegadget for more convenient typing
* Make the output format cleaner
* Add a simple cache mechanism for the one_gadget output
* Update the warning message
* Use MD5 instead of BLAKE2 for computing the file hash
I thought that BLAKE2 was faster than MD5, but it doesn't seem correct here somehow (probably because of the implementation of Python!?)
Here's the script I used for benchmarking:
```python
import hashlib
import timeit
def compute_file_hash_1() -> str:
h = hashlib.blake2b()
with open("/lib/x86_64-linux-gnu/libc.so.6", "rb") as f:
h.update(f.read())
return h.hexdigest()
def compute_file_hash_2() -> str:
h = hashlib.md5()
with open("/lib/x86_64-linux-gnu/libc.so.6", "rb") as f:
h.update(f.read())
return h.hexdigest()
print(timeit.timeit(compute_file_hash_1, number=1000))
print(timeit.timeit(compute_file_hash_2, number=1000))
```
I executed the above script on various machines, and the results seem to show that MD5 outperforms BLAKE2 in this scenario. (On my x86 VM running through QEMU on my M1 MacBook, BLAKE2 even takes almost twice as long as MD5.)
* Add the tests for `onegadget` command
* Fix lint issue
* Try to cover more code
* Fix lint issue
* Fix illogical tests
* Rename one_gadget to onegadget
* Use `pwndbg.lib.tempfile.cachedir` for `onegadget`
* Call `pwndbg.lib.tempfile.cachedir` only once
* Add support for breaking on UAF
* Small fixes and documentation
* Add a command to enable and disable tracking, better diagnostics
* Add initial support for calloc and realloc
* Better safeguard against matching ld.so malloc
* Small fixes
* Better interface for managing the heap tracker. More terse and information dense diagnostics
* Add warning and fix lints
* Update poetry lock
Hopefully fixes#1947 by fetching stacks only when they are used instead
of doing it on each stop event. It will also first try to compute stacks
dictionary based on vmmap and if it fallbacks to exploring stacks if
vmmap is not present.
* [WIP] Port gdb-tests from bash to python
* Use threads instead of processes
* Port gdb tests to python
* Linting
* Fix coverage "again"
* Remove bash tests
