* image list: speed upValentin Rothberg2020-08-11
| | | | | | | | | | | | | | | | | | | | | | | Listing images has shown increasing performance penalties with an increasing number of images. Unless `--all` is specified, Podman will filter intermediate images. Determining intermediate images has been done by finding (and comparing!) parent images which is expensive. We had to query the storage many times which turned it into a bottleneck. Instead, create a layer tree and assign one or more images to nodes that match the images' top layer. Determining the children of an image is now exponentially faster as we already know the child images from the layer graph and the images using the same top layer, which may also be considered child images based on their history. On my system with 510 images, a rootful image list drops from 6 secs down to 0.3 secs. Also use the tree to compute parent nodes, and to filter intermediate images for pruning.

* Remove hijacked connections from active connections listKorhonen Sami (Samlink)2020-07-22
| | | | | | | | | | | | | | | | | | | | | | | StateHijacked is a terminal state. If hijacked connection is registered as an active connection, connection will never be unregistered. This causes two issues First issue is that active connection counters are off. Second issue is a resource leak caused by connection object that is stored to a map. After this patch hijacked connections are no longer visible in counters. If a counter for hijacked connections is required, podman must track connections returned by Hijacker.Hijack() It might make sense to develop abstraction layer for hijacking - and move all hijacking related code to a separate package. Hijacking code is prone to resource leaks and it should be thoroughly tested. Signed-off-by: Sami Korhonen <skorhone@gmail.com>
* Correctly print STDOUT on non-terminal remote execMatthew Heon2020-07-22
| | | | | | | | | | | | | | I confused STDIN and STDOUT's file descriptors (it's 0 and 1, I thought they were 1 and 0). As such, we were looking at whether we wanted to print STDIN when we looked to print STDOUT. This bool was set when `-i` was set in at the `podman exec` command line, which masked the problem when it was set.

* Fix container and pod create commands for remote createMatthew Heon2020-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | In `podman inspect` output for containers and pods, we include the command that was used to create the container. This is also used by `podman generate systemd --new` to generate unit files. With remote podman, the generated create commands were incorrect since we sourced directly from os.Args on the server side, which was guaranteed to be `podman system service` (or some variant thereof). The solution is to pass the command along in the Specgen or PodSpecgen, where we can source it from the client's os.Args. This will still be VERY iffy for mixed local/remote use (doing a `podman --remote run ...` on a remote client then a `podman generate systemd --new` on the server on the same container will not work, because the `--remote` flag will slip in) but at the very least the output of `podman inspect` will be correct. We can look into properly handling `--remote` (parsing it out would be a little iffy) in a future PR.

* When determining systemd mode, use full commandMatthew Heon2020-07-22
| | | | | | | | | | | | | | | | | | We were only using the Command field in specgen when determining whether to enable systemd if systemd=true (the default) was used. This does not include the entrypoint, and does not include any entrypoint/command sourced from the image - so an image could be running systemd and we'd not correctly detect this. Using the full, final command resolves this and matches Podman v1.9.x behavior.

* Fix & add notes regarding problematic language in codebaseAshley Cui2020-07-22
| | | | | | | | 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.

| * events endpoint: backwards compat to old typeValentin Rothberg2020-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The versions Docker that the compat endpoints currently support are using another type for the `filters` parameter than later versions of Docker, which the libpod/events endpoint is also using.

| * events endpoint: fix panic and race conditionValentin Rothberg2020-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a potential panic in the events endpoint when parsing the filters parameter. Values of the filters map might be empty, so we need to account for that instead of uncondtitionally accessing the first item. Also apply a similar for race conditions as done in commit f4a2d25c0fca: Fix a race that could cause read errors to be masked. Masking such errors is likely to report red herrings since users don't see that reading failed for some reasons but that a given event could not be found. Another race was the handler closing event channel, which could lead to two kinds of panics: double close, send to close channel. The backend takes care of that. However, make sure that the backend stops working in case the context has been cancelled. Fixes: #6899 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* search: allow wildcardsValentin Rothberg2020-07-15
| | | | | | | | | | | | | | | | | | | Allow wildcards in the search term. Note that not all registries support wildcards and it may only work with v1 registries. Note that searching implies figuring out if the specified search term includes a registry. If there's not registry detected, the search term will be used against all configured "unqualified-serach-registries" in the registries.conf. The parsing logic considers a registry to be the substring before the first slash `/`. With these changes we now not only support wildcards but arbitrary input; ultimately it's up to the registries to decide whether they support given input or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I didn't believe that this was actually legal, but it looks like it is. And, unlike our previous understanding (host port being empty means just use container port), empty host port actually carries the same meaning as `--expose` + `--publish-all` (that is, assign a random host port to the given container port). This requires a significant rework of our port handling code to handle this new case. I don't foresee this being commonly used, so I optimized having a fixed port number as fast path, which this random assignment code running after the main port handling code only if necessary.

| * Print errors from individual containers in podsMatthew Heon2020-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The infra/abi code for pods was written in a flawed way, assuming that the map[string]error containing individual container errors was only set when the global error for the pod function was nil; that is not accurate, and we are actually *guaranteed* to set the global error when any individual container errors. Thus, we'd never actually include individual container errors, because the infra code assumed that err being set meant everything failed and no container operations were attempted. We were originally setting the cause of the error to something nonsensical ("container already exists"), so I made a new error indicating that some containers in the pod failed. We can then ignore that error when building the report on the pod operation and actually return errors from individual containers. Unfortunately, this exposed another weakness of the infra code, which was discarding the container IDs. Errors from individual containers are not guaranteed to identify which container they came from, hence the use of map[string]error in the Pod API functions. Rather than restructuring the structs we return from pkg/infra, I just wrapped the returned errors with a message including the ID of the container. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Set syslog for exit commands on log-level=debugMatthew Heon2020-06-25
| | | | | | | | | | | | | | | | We have a flag, --syslog, for telling logrus to log to syslog as well as to the terminal. Previously, this flag also set the exit command for containers to use `--syslog` (otherwise all output from exit commands is lost). I attempted to replicate this with Podman v2.0, but quickly ran into circular import hell (the flag is defined in cmd/podman, I needed it in cmd/podman/containers, cmd/podman imports cmd/podman/containers already, etc). Instead, let's just set the syslog flag automatically on `--log-level=debug` so we log exit commands automatically when debug-level logs are requested.
