* add missing install dep for shfmt
* if we're given an ubuntu version and its not 20.04.. then install shfmt
* fix broken check for if no argument was passed to install_apt
* Only run arch for testing
* Remove outdated arch repo
* Actually build the docker image
* Do not include site packages in sys.path
* Ignore `.relr.dyn` section; skip lines w/o spaces
Newer binaries can contain a `.relr.dyn` section to compress `R_X86_64_RELATIVE` relocation entries.
These binaries can be found for example on archlinux but also on Debian 12 for example.
`readelf` prints the content of the section similarly to this:
```
Relocation section '.relr.dyn' at offset 0x25220 contains 35 entries:
1198 offsets
00000000001ce8d0
00000000001ce8e0
```
Compared to `00000000001d2000 0000000000000025 R_X86_64_IRELATIVE 9f330` for
`.rela.plt`.
Pwndbg now chokes on the new format because it expects a space seperator where there is none.
It might be, that this is actually an upstream problem with binutils, because llvm-readelf prints this:
```
Relocation section '.relr.dyn' at offset 0x25220 contains 1198 entries:
Offset Info Type Symbol's Value Symbol's Name
00000000001ce8d0 0000000000000008 R_X86_64_RELATIVE
00000000001ce8e0 0000000000000008 R_X86_64_RELATIVE
```
Nevertheless, we aren't actually interested in `R_X86_64_RELATIVE` relocations so I guess it's fine to
just skip all lines that contain no spaces at all.
`.relr.dyn` can only containt `R_X86_64_RELATIVE` relocations as far as I understand

* Accept Full RELRO in test
Archlinux has libc and ld with Full RELRO.
We now just accept Partial and Full RELRO.
* Do not copy binaries from host to docker
The `Dockerfile` copies the whole pwndbg folder to the image.
If we have built binaries on the host before, these binaries will contain references to
the host system and *copied* to the image.
If we now run `context code` (inside docker) to have a look at the source code this will
fail, because we will try to refer to a path on the host system.
* Do not use loop index after loop
Do not use loop index after the loop. The tests assumed that the loop in line 186
would run at least once, thereby *resetting* `i` to zero. If we never enter the
loop, `i` will *continue* to have the value it had at the end of line 172.
This will cause the test to fail in mysterious ways because `i` is now not reset
to zero but still has the value `31` for example.
The solution is to never use `i` outside of a loop.
* Re-enable archlinux and temporarily disabled ones
* Change setup.sh to create & use Python virtualenv
The `setup.sh` script now creates a `.venv` directory during execution and installs all dependencies into that directory. Then, `gdbinit.py` will adds the proper `site-packages` directory as the first item of `sys.path`.
Fixes#1634.

* Fix Arch CI: install missing netcat (#1400)
The arch linux test_command_procinfo was failing bcoz the netcat was not
installed on arch build. This commit fixes it by:
1) installing gnu-netcat for arch linux setup-dev.sh
2) asserting that nc is available in the test itself, to prevent similar
regressions from happening on future/newer images
* Fix Arch CI: the load binary tests (#1400)
Before this commit we asserted whether the loaded binary in tests report
to find or not find debug symbols but this is irrelevant for the thing
we want to test there which is: pwndbg loading. What eventually cares is
whether Pwndbg got loaded and didn't raise an exception.
This commit fixes those tests so they should now work also on ArchLinux
CI and on all CI builds.
Additionally, it removes the `compile_binary` test utility function
which was redundant as we compile all test binaries via a makefile.
* fix lint
* cleanup tests/binaries/div_zero_binary
* fix shlint
* Fix crash when unable to get ehdr and fix vmmap coredump test
This commit fixes two issues and test them.
1. It changes the reads in `get_ehdr` to partial reads so that inability
to read the `vmmap.start` address there will not crash Pwndbg with
`gdb.error` but instead we will simply return `None` as expected from
this function. This crash could happen on Debian 10 (GDB 8.2.1) and
Ubuntu 18.04 (not sure which GDB) when you did:
- gdb ./binary-that-crashes
- `run`
- `generate-core-file /tmp/core`
- `file` - to unload the binary
- `core-file /tmp/core` - to load the generated core
At this point I think we may have preserved the old vmmap info and use
it in `get_ehdr` maybe, which then crashed? I am not sure, but this fix
here works.
To test this behavior properly I also added the `unload_file`
parametrization to the
`test_command_vmmap_on_coredump_on_crash_simple_binary` test.
2. We fix the vmmap coredump test case when the `info proc mappings` returns nothing on core
dumps on old GDBs. In such case we are missing the vmmap info about
the binary mapping, so now we properly remove it in the test.
* Specify dockerfile for ubuntu/debian
To add Dockerfile.arch later
* Support Arch Linux docker test
* Fix setup-dev supported distro
* Create set_zigpath function
* Download zig from upstream for archlinux
* Add hash as part of key for docker cache
as https://github.com/satackey/action-docker-layer-caching#inputs notes.
