Graphene IPC (GIPC) was introduced to perform faster bulk IPC by sharing pages as copy-on-write
across processes. This feature became stale, and it was shown that recent Linux kernels (4.2+)
have zero-copy transfers over UNIX sockets and exhibit similar performance. GIPC is not built and
not tested in Jenkins. Also, GIPC does not work under SGX. This commit completely removes GIPC.
The pipeline is failed only when pylint whines about the code actually
touched as part of the pull request.
The `run-shellcheck` script is provided so it can be reused, maybe in
`.git/hooks/pre-push`.
These tests perform common FS operations in various ways:
- open/close
- read/write
- create/delete
- read/change size
- seek/tell
- memory-mapped read/write
- copy directory in different ways
Tests use both direct syscalls and stdio wrappers (FILE).
To run, call `make test` in `LibOS/shim/test/fs`.
The academic-quality build script was supplanted by industry-grade
Makefile rule.
Also, glibc 2.19 is not supported, because it is not present in any
supported distro.
There are two Python3 examples now:
- python-simple contains simple and secure Python3 scripts;
- python-scipy-insecure contains SciPy and NumPy insecure Python3 scripts.
Both examples are tested in Jenkins.
Previously, Graphene supported Glibc version 2.19 only. This commit
adds support for Glibc v2.23 (default in Ubuntu 16.04) and Glibc
v2.27 (default in Ubuntu 18.04). The exact version can be chosen by
specifying GLIBC_VERSION during Graphene build. The default version
to be built is v2.27.
Note that for the best GDB experience it is advised to build Graphene
with the same Glibc version as installed on the host OS.
Run CI in a Docker image
* Wait a second for lighttp and apache to fully initialize the socket
* Try to add a timeout for lmbench, which is prone to hanging (vfork)
* Set a timeout on gcc; one of the PRs is causing gcc hello to hang. Also, to avoid interference, run apache test on 8001 by default.
* Update lmbench to ignore bin dir
* Do the faster tests first; fail earlier
* Get the IP addr properly for web server tests
* Some notes on flaky LTP tests to debug later. Move a few that tend to heisenbugs off of the required list for now
* Try to detect vma list corruption during the debug dump, lest it be infinite.
* Temporarily disable the lmbench vfork test (Issue #142).
* Catch some failures faster.
* Catch failures in apachebench
* Take apache out of the Linux host/Debug build CI for now, as it hangs consistently. Filed issue #144 to track.
* Migrate running unit tests for Linux host to Jenkins. Add a unit test for the Linux host, Debug build
* Ignore files generated as part of unit testsing.
* A quick and dirty fix for port collisions during CI tests. Come back and do a better job if we continue having problems
* For some reason, the PAL Process regression tests fail using the default manifest under a debug build. Go ahead and explicate a template for the Process test.
