* e2e tests: use Should(Exit()) and ExitWithError()Ed Santiago2021-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | e2e test failures are rife with messages like: Expected 1 to equal 0 These make me cry. They're anti-helpful, requiring the reader to dive into the source code to figure out what those numbers mean. Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I don't know if it spits out a better diagnostic (I have no way to run e2e tests on my laptop), but I have to fantasize that it will, and given the state of our flakes I assume that at least one test will fail and give me the opportunity to see what the error message looks like. THIS IS NOT REVIEWABLE CODE. There is no way for a human to review it. Don't bother. Maybe look at a few random ones for sanity. If you want to really review, here is a reproducer of what I did: cd test/e2e ! positive assertions. The second is the same as the first, ! with the addition of (unnecessary) parentheses because ! some invocations were written that way. The third is BeZero(). perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go ! Same as above, but handles three non-numeric exit codes ! in run_exit_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go ! negative assertions. Difference is the spelling of 'To(Not)', ! 'ToNot', and 'NotTo'. I assume those are all the same. perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go ! negative, old use of BeZero() perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go Run those on a clean copy of main branch (at the same branch point as my PR, of course), then diff against a checked-out copy of my PR. There should be no differences. Then all you have to review is that my replacements above are sane. UPDATE: nope, that's not enough, you also need to add gomega/gexec to the files that don't have it: perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}')) UPDATE 2: hand-edit run_volume_test.go UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places UPDATE 4: skip a test due to bug #10935 (race condition) Signed-off-by: Ed Santiago <santiago@redhat.com>
* Ensure that `--userns=keep-id` sets user in configMatthew Heon2021-04-06
| | | | | | | | | | | | | | | | | | | | | | | One of the side-effects of the `--userns=keep-id` command is switching the default user of the container to the UID of the user running Podman (though this can still be overridden by the `--user` flag). However, it did this by setting the UID and GID in the OCI spec, and not by informing Libpod of its intention to switch users via the `WithUser()` option. Because of this, a lot of the code that should have triggered when the container ran with a non-root user was not triggering. In the case of the issue that this fixed, the code to remove capabilities from non-root users was not triggering. Adjust the keep-id code to properly inform Libpod of our intention to use a non-root user to fix this. Also, fix an annoying race around short-running exec sessions where Podman would always print a warning that the exec session had already stopped.

* Improve error messages from failing testsDebarshi Ray2020-11-03
| | | | | | | | | | Using a function like ContainSubstring or Equal is better because if the test fails it will log a descriptive error that includes the actual string generated during the test.

| | | | | | | | | | Test passes on Fedora because the registry server is one of the defaults. However it is not typically configured on Ubuntu hosts, and therefor this test can fail.

* Preserve groups in exec sessions in ctrs with --userMatthew Heon2020-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman wants to guarantee that exec sessions retain the groups of the container they are started in, unless explicitly overridden by the user. This guarantee was broken for containers where the `--user` flag was specified; this patch resolves that. Somewhere in the Exec rewrite for APIv2, I changed the location where the container's User is passed into the exec session (similar to groups, we also want to preserve user unless overridden). The lower-level Exec APIs already handled setting user and group appropriately if not specified when the exec session was created, but I added duplicate code to handle this higher in the stack - and that code only handled setting user, not supplemental groups, breaking support in that specific case. Two things conspired to make this one hard to track down: first, things were only broken if the container explicitly set a user; otherwise, the container user would still appear to be unset to the lower-level code, which would properly set supplemental groups (this tricked our existing test into passing). Also, the `crun` OCI runtime will add the groups without prompting, which further masked the problem there. I debated making `runc` do the same, but in the end it's better to fix this in Podman - it's better to be explicit about what we want done so we will work with all OCI runtimes.

* Ensure that exec errors write exit codes to the DBMatthew Heon2020-08-05
| | | | | | | | | | | | | | | | | | | In local Podman, the frontend interprets the error and exit code given by the Exec API to determine the appropriate exit code to set for Podman itself; special cases like a missing executable receive special exit codes. Exec for the remote API, however, has to do this inside Libpod itself, as Libpod will be directly queried (via the Inspect API for exec sessions) to get the exit code. This was done correctly when the exec session started properly, but we did not properly handle cases where the OCI runtime fails before the exec session can properly start. Making two error returns that would otherwise not set exit code actually do so should resolve the issue. Fixes #6893 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Correctly print STDOUT on non-terminal remote execMatthew Heon2020-07-10
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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].

* Do not share container log driver for execMatthew Heon2020-06-17
| | | | | | | | | | | | | | | | | | | | | When the container uses journald logging, we don't want to automatically use the same driver for its exec sessions. If we do we will pollute the journal (particularly in the case of healthchecks) with large amounts of undesired logs. Instead, force exec sessions logs to file for now; we can add a log-driver flag later (we'll probably want to add a `podman logs` command that reads exec session logs at the same time). As part of this, add support for the new 'none' logs driver in Conmon. It will be the default log driver for exec sessions, and can be optionally selected for containers. Great thanks to Joe Gooch (mrwizard@dok.org) for adding support to Conmon for a null log driver, and wiring it in here. Fixes #6555 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Enable detached exec for remoteMatthew Heon2020-06-02
| | | | | | | | | | | | | | | | | | | | | | | The biggest obstacle here was cleanup - we needed a way to remove detached exec sessions after they exited, but there's no way to tell if an exec session will be attached or detached when it's created, and that's when we must add the exit command that would do the removal. The solution was adding a delay to the exit command (5 minutes), which gives sufficient time for attached exec sessions to retrieve the exit code of the session after it exits, but still guarantees that they will be removed, even for detached sessions. This requires Conmon 2.0.17, which has the new `--exit-delay` flag. As part of the exit command rework, we can drop the hack we were using to clean up exec sessions (remove them as part of inspect). This is a lot cleaner, and I'm a lot happier about it. Otherwise, this is just plumbing - we need a bindings call for detached exec, and that needed to be added to the tunnel mode backend for entities. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add bindings for exec and enable attached remoteMatthew Heon2020-06-01
| | | | | | | | | | | This adds bindings for starting exec sessions, and then uses them to wire up detached exec. Code is heavily based on Attach code for containers, slightly modified to handle exec sessions. Bindings are presently attached-only, detached is pending on a Conmon update landing in CI. I'll probably get to that next. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
