* The cidfile should be created when the container is createdDaniel J Walsh2020-10-26
| | | | | | | | | | | Currently if you run an interactive session of podman run and specifiy the --cidfile option, the cidfile will not get created until the container finishes running. If you run a detached container, it will get created right away. This Patch creates the cidfile as soon as the container is created. This could allow other tools to use the cidefile on all running containers. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Convert Split() calls with an equal sign to SplitN()TomSweeneyRedHat2020-10-13
| | | | | | | | | | | | | | | | After seeing #7759, I decided to look at the calls in Podman and Buildah to see if we had issues with strings.Split() calls where an "=" (equals) sign was in play and we expected to split on only the first one. There were only one or two that I found in here that I think might have been troubling, the remainder are just adding some extra safety. I also had another half dozen or so that were checking length expectations appropriately, those I left alone. Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com>
* Remove excessive error wrappingKir Kolyshkin2020-10-05
| | | | | | | | | | | | | | | | | In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like fails, the error message already contains the file name and the operation that fails, so there is no need to wrap the error with something like "open %s failed". While at it - replace a few places with os.Open, ioutil.ReadAll with ioutil.ReadFile. - replace errors.Wrapf with errors.Wrap for cases where there are no %-style arguments.

* Fix & add notes regarding problematic language in codebaseAshley Cui2020-07-15
| | | | | | | | Podman is committed to inclusivity, a core value of open source. Historically, there have been technology terms that are problematic and divisive, and should be changed. We are currently taking time to audit our repository in order to eliminate such terminology, and replace it with more inclusive terms. We are starting where we can, with our own code, comments, and documentation. However, such terms may be used in dependencies, and must be used in our repositories at the current moment for compatibility. Podman will change these terms in our repo as soon as new and better terminology is available to us via our dependencies.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* libpod: fix --userns=keep-id with big UIDsGiuseppe Scrivano2020-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | when creating a keep-id namespace, we split the original user namespace in: inner ns | outer ns | size: 0 | 1 | ID ID | 0 | 1 ID+1 | ID+1 | availableIds - ID When the user ID is bigger than the number of available subuids/subgids we fail to create the user namespace because the first slice is bigger than the available number of IDs and the third one has a negative size. Fix it by not using more than the available number of IDs in the first slice and creating the third one only if there are other IDs left. When the user ID is bigger than the number of additional IDs, there will be a gap between the two mappings so the IDs between the maximum additional ID and the user ID won't be present inside of the namespace.

* signal parsing - better input validationEd Santiago2019-12-26
| | | | | | | | | | | | | | | | | | | | | | The helper function we use for signal name mapping does not check for negative numbers nor invalid (too-high) ones. This can yield unexpected error messages: # podman kill -s -1 foo ERRO[0000] unknown signal "18446744073709551615" This PR introduces a small wrapper for it that: 1) Strips off a leading dash, allowing '-1' or '-HUP' as valid inputs; and 2) Rejects numbers <1 or >64 (SIGRTMAX) Also adds a test suite checking signal handling as well as ensuring that invalid signals are rejected by the command line.

* Add ONBUILD support to --changeMatthew Heon2019-12-05
| | | | | | | | | | | Return types had to change a bit for this, but since we can wrap the old v1.ImageConfig, changes are overall not particularly bad. At present, I believe this only works with commit, not import. This matches how things were before we changed to the new parsing so I think this is fine.

* Completely rework --change parsingMatthew Heon2019-12-04
| | | | | | | | | | | | The way we were trying to parse was very broken. I originally attempted to use Buildah's Dockerfile parser here, but dealing with it (and convincing it to accept only a limited subset, and only one instruction at a time) was challenging, so I rewrote a subset of Dockerfile parsing. This should handle most common cases well, though there are definitely unhandled edge cases for ENV and LABEL. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | This requires updating all import paths throughout, and a matching buildah update to interoperate. I can't figure out the reason for go.mod tracking github.com/containers/image v3.0.2+incompatible // indirect ((go mod graph) lists it as a direct dependency of libpod, but (go list -json -m all) lists it as an indirect dependency), but at least looking at the vendor subdirectory, it doesn't seem to be actually used in the built binaries.
