* 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.
