name: Flow-IPC pipeline | |
# Discussion on the philosophy behind the workflow (pipeline) below. The steps themselves should be easy enough to | |
# follow, but what's the bigger picture? Answer: The pipeline below is an algorithm, as coded below, invoked | |
# by GitHub on many runners (machines); and the inputs to this algorithm are: | |
# - a branch (`main`, or a feature/PR branch) or tag (usually release tag v<version>); | |
# - hence the current contents of that branch/tag; | |
# - some trigger event that causes the workflow (pipeline) to run in the first place: | |
# push to the branch/tag; pull request (PR) creation; or manual click by human (as of this writing usually | |
# for testing or debugging only). | |
# So given those inputs, what are the outputs or side effects? To answer, consider what jobs are actually run | |
# (as parallel as possible). There's `setup` and `set-vars` as of this writing, but these are | |
# purely tactical prerequisites and not worth discussing here; once they complete then the "real" jobs will run: | |
# build-and-test and doc-and-release. Here are their goals, meaning outputs/side effects given the above | |
# inputs: | |
# - build-and-test: | |
# - Summary: Test building and running the product; and bullet-proof it further via run-time sanitizers. | |
# - Build the code, including demo/test code, at the given branch/tag in wide variety of compiler/build-type | |
# combinations. The ability to build (including linking into test binaries) successfully is, of course, | |
# a test in and of itself. | |
# - Test that code by running the available unit test and integration test/demo binaries built in previous bullet. | |
# If something fails, help (within reason) make it clear what failed and why. | |
# - Output: Make any logs available, whether on success or failure. If console output is sufficient, | |
# great: it'll be visible via GitHub Actions UI. If not, save the non-console log output in a log tarball | |
# available as workflow artifact for download via GitHub Actions UI. | |
# - All of the above but with certain run-time sanitizers (as of this writing ASAN/LSAN, UBSAN, TSAN, | |
# and possibly clang-MSAN) enabled at build time as well. (RelWithDebInfo is a sufficient base build type | |
# for a sanitizer-enabled build; a subset of compilers -- as opposed to all of them -- is also sufficient | |
# for pragamtic reasons.) | |
# - doc-and-release: | |
# - Summary: 1, generate documentation from the source code (using Doxygen et al) and make it conveniently | |
# available. 2, update GitHub Release and GitHub Pages web site with automatically with any relevant info, namely | |
# with the generated docs and source code tarball/zip. | |
# - Generate the documentation using Doxygen et al. The goal here is the *canonical generated documentation*, not | |
# *testing the ability to generate it*. It's a subtle difference, but it's important to note it, because | |
# if we wanted to test the ins and outs of doc generation in various environments then we could have a much more | |
# complex and longer pipeline -- and perhaps we should... but that's not the goal *here*. | |
# - Output: Make it available as workflow artfiact for download via GitHub Actions UI. | |
# Hence human can simply download it, whether it's for the `main` tip or a specific release version. | |
# - Side effect: (On pushes/merges to `main` branch *only*) Check-in the *generated docs* back into `main` | |
# itself, so that (1) they're available for local perusal by any person cloning/pulling `main` and (2) ditto | |
# for any downstream releases (which are mere tags of `main`). | |
# - Side effect: Having done so, signal GitHub Pages web site for the org, so that the new `main` docs | |
# are reflected at this web site. (It'll automatically clone `main`, copy the generated docs to web site | |
# replacing the existing `main` docs if any, and stage this to the web.) | |
# - (If the branch/tag input is, in fact, tag v* -- a release tag) The mere fact that a push to a release tag X | |
# is being observed means we want: | |
# - Side effect: Ensure that the GitHub Release X has the full source code available for human download | |
# as a package (tarball/zip). I.e., upload it there as needed. | |
# - Side effect: Ensure that the GitHub Pages web site actually lists this Release and its associated | |
# generated documentation. I.e., signal Pages that there's a Release X now: it'll then do the right | |
# thing (namely checkout the docs at the tag and copy them over; and add a link to the release and docs | |
# in the appropriate web page). | |
# | |
# So, roughly speaking, | |
# - build-and-test is about building and testing the product, including bullet-proofing it with sanitizers. | |
# - doc-and-release is about official documentation-based-on-source being available in various customary ways; | |
# with a side of official releases being accessible and comprehensively presented in customary ways. | |
# - TODO: It *could* be argued that those 2 goals are related but separate, and perhaps they should be 2 separate | |
# jobs. However, at least as of this writing, there's definite overlap between them, and combining the 2 | |
# makes pragamtic sense. It's worth revisiting periodically perhaps. | |
on: | |
# Want to merge to development tip? Should probably pass these builds/tests and doc generation first (the latter | |
# in case the source change adds a Doxygen error or bad-looking docs). Note this runs on PR creation *and* update. | |
pull_request: | |
branches: | |
- main | |
push: | |
# Was able to merge PR to `main` tip? Should ensure these builds/tests/doc generation still pass after the fact | |
# (post-merge `main` does not always equal the PR-branch state); plus: | |
# auto-check-in generated docs into `main` branch tip (and signal web site to update accordingly). | |
branches: | |
- main | |
# Created release tag? Just in case, should ensure these builds/tests pass (just in case, but it's redundant | |
# against the branch=main trigger above); generate docs and make them available as artifact (nice: docs for | |
# a particular product version available online); plus: | |
# signal web sites to update accordingly (there's probably a new release to present, with full source code attached; | |
# and there are docs for; nice: docs a particular product version available online). | |

# We concentrate on clang sanitizers; they are newer/nicer; also MSAN is clang-only. So gcc ones excluded. | |
# Attention! Excluding some sanitizer job(s) (with these reasons): | |
# - MSAN: MSAN protects against reads of ununitialized memory; it is clang-only (not gcc), unlike the other | |
# *SAN. Its mission overlaps at least partially with UBSAN's; for example for sure there were a couple of | |
# uninitialized reads in test code which UBSAN caught. Its current state -- if not excluded -- is as | |
# follows: 1, due to (as of this writing) building dependencies, including the capnp compiler binary used | |
# during our build process, with the same compiler build config as the real code, ignore-list entires had | |
# to be added to get past these problems. 2, before main() in *all* our demos/tests Boost was doing some | |
# global init which MSAN did not like and hence aborted before main(); these are now ignored as well. | |
# 3, this got us into main() at least, but immediately cryptic aborts started, seemingly again originating | |
# in Boost (but requires detailed investigation to really understand). At this point I (ygoldfel) | |
# disabled MSAN and filed a ticket. The overall status: MSAN is said to be useful, even with UBSAN active, | |
# but all resources including official docs indicate that it is a high-maintenance tool: | |
# *All* linked code, including libc and libstdc++/libc++ (the former in our case as of this writing), | |
# must be instrumented to avoid cryptic false positives. The good news is we do build other things | |
# instrumented (Boost libs, jemalloc, capnp/kj, gtest); but not libstdc++ (which official docs recommend); | |
# this can be done but requires more work (I would suggest switching to libc++ in that case from the | |
# start, as the clang people made it and themselves build it instrumented for their testing). | |
# So the bottom line: MSAN is a tough cookie and requires more work before enabling. In the meantime we | |
# have many layers of protection, including ASAN and UBSAN and lots of unit and integration tests. | |
# So this status quo is pretty good. TODO: Do the work/get MSAN functional/useful; un-exclude it then. | |
# - *SAN with gcc: We concentrate on clang sanitizers; they are newer/nicer; having to worry about differences | |
# between them is an excessive burden. So excluding gcc ASAN/UBSAN/TSAN. | |
# - TODO: Consider reducing to the newest or most stable clang. Generally they just keep improving; the | |
# chances of something being uncaught (incorrectly) with a later version are slim. Not impossible though. | |
# Look into it. Update: As of this writing transport_test exercise mode/SHM-jemalloc sub-mode is | |
# disabled for TSAN clang-17 due to instability of TSAN itself. So clearly when it comes to TSAN | |
# (which is officially in beta as of clang-17), higher version does not mean everything is better. | |
# Hence perhaps this to-do is more of a longer-term thing, when all the sanitizers stabilize, or when | |
# we find a single very-stable config. Just remember we aren't testing the sanitizer or our code's | |
# ability to be sanitized; we just want to detect any problems in the code -- however we get there. | |
# - *SAN with clang-13 (but not 15+): As of this writing clang-13 produces some additional warnings, | |
# at least in TSAN, which appear to be related to nearby non-race messages like | |
# `==75454==WARNING: Symbolizer buffer too small`. As a result, we either have to eliminate the | |
# latter problem (TODO: look into it) or suppress false-positive race warnings that might only look | |
# like added problems due to the incomplete stack traces. In general scanning through clang-13-produced | |
# TSAN output, there is a chaotic feel to it, when it comes to stack output. Meanwhile so far | |
# there has been zero evidence that a lower-version clang has actual added problems versus the other | |
# compiler-versions, due to generating code differently. Since we have at least 3 other compiler-versions | |
# running all the *SAN, I (ygoldfel) decided to exclude clang-13 *SAN, until the chaotic *SAN messages can | |
# be at least reduced. In the meantime our *SAN coverage is still quite good. | |

# sanitizers; but it is accepted for ASAN and TSAN, seemingly, and maybe is at worst | |
# harmless with out compiler versions. TODO: Maybe revisit. | |
# | |
# print_stacktrace=1 for UBSAN is recommended by documentation for nice stack traces | |
# (also that is why we apply sanitizers to RelWithDebInfo; DebInfo part for the nice | |

# seems like it would be harmless and avoid the `if/elif`s... but is actually a | |
# nightmare; there is some interaction in clang (at least 13-17) which causes the | |

# (capnp compiler binary; temp binaries created by auto-tools configure scripts to test features). | |
# In the case of the libs that's usually good; in particular things like | |
# -fsanitize=address (ASAN) (for build-type relwithdebinfo-asan) ideally are applied to all built code | |
# uniformly. (There are other libs being built, one can see: at least openssl and zlib; they're not really | |
# involved in our actual product, at least not in a core way, so for those it arguably matters less either way.) | |
# In the case of the binaries it is usually bad; we want the fastest, most normal tools possible, not ones | |
# built weirdly with whatever settings we're trying to test with our own software. For one it makes those | |
# tools slower -- perhaps not the hugest deal in practice here -- but it also generally increases entropy; and | |
# it has also resulted in various pain: | |
# - Cannot use -fno-sanitize-recover with UBSAN (abort program on warning) if we wanted to: it causes some | |
# hidden configure-script-generated binary abort => capnp binary build fails. | |
# - capnp binary fails MSAN at startup; hence capnp-compilation of our .capnp schemas fails. | |
# We have worked around all these, so the thing altogether works. It's just somewhat odd and entropy-ridden; | |
# and might cause maintanability problems over time, as it has already in the past. | |
# The TODO is to be more judicious about it | |
# and only apply these things to the libs/executables we want it applied. It is probably not so simple; | |
# but worst-case it should be possible to use something like build-type-cflags-override to target our code; | |
# and per-recipe (Boost, jemalloc, gtest...) techniques to target others; and not use the aggressive | |
# conan-profile-custom-conf and conan-profile-custom-buildenv. That said, there will be interesting subtleties | |
# like: libcapnp/kj are linked into capnp compiler binary; *and* to our code. So we should instrument it with | |
# sanitizer (when applicable); now some of the capnp-compiler-binary is instrumented; some isn't. Would that | |
# work, or would it be better to build capnp twice then (once for the binary, once for the linked libraries)? | |

# We need to prepare a sanitizer ignore-list in MSAN mode. Background for this is subtle and annoying: | |
# As it stands, whatever matrix compiler/build-type is chosen applies not just to our code (correct) | |
# and 3rd party libraries we link like lib{boost_*|capnp|kj|jemalloc} (semi-optional but good) but also | |
# unfortunately any items built from source during "Install Flow-IPC dependencies" step that we then | |
# use during during the build step for our own code subsequently. At a minimum this will slow down | |
# such programs. (For the time being we accept this as not-so-bad; to target this config at some things | |
# but not others is hard/a ticket.) In particular, though, the capnp compiler binary is built this way; | |
# and our "Build targets" step uses it to build key things (namely convert .capnp schemas into .c++ | |
# and .h sources which are then themselves compiled/used in compilation). In the case of MSAN, this | |
# version of capnp compiler happens to trigger several MSAN failures (presumably they are not a true | |
# problem, and it's not our job really to sanitize capnp -- though we can file tickets for them and/or | |
# issue PRs; but I digress). So in MSAN mode our build step fails, when capnp compiler itself aborts | |
# with MSAN failures. One approach is to not apply MSAN to capnp compiler (no-go for now; it's a ticket | |
# as mentioned); another is to uses Conan to patch capnp package for them (not a bad idea; ticket filed); | |
# and lastly we can put the specific failures on the ignore-list for MSAN. For now we do that; while | |
# unpleasant it does get the job done. TODO: Revisit/resolve tickets/improve (see above). | |

# From now on save logs in install-dir/bin/logs. They will be tarred up and uploaded | |
# as artifacts at the end. For those tests below that produce separate logs as files | |
# to begin-with, this is a no-brainer. For those (as of this writing the main one | |
# is unit_test; but also the link tests produce short logs too) who use stdout/stderr | |
# the reason to do this is 2-fold. | |
# - UBSAN in particular produces non-fatal error output about problems it detects. | |
# We need to analyze them after the fact and fail a step below in that case to | |
# alert developers who would then fix such new problems. | |
# - One can also build UBSAN-mode things with -fno-sanitize-recover which would | |
# cause abnormal program exit on *first* error. We do not do this for these | |
# reasons: | |
# - It is more convenient to let it continue and thus show all problems in one | |
# shot. | |
# - There is a side problem: At this time compile settings, including | |
# in UBSAN case `-fsanitize=undefined -fno-sanitize-recover`, are applied not | |
# just to our code or 3rd party libraries but also any other stuff built | |
# (due to setting C[XX]FLAGS in Conan profile). Targeting just the exact | |
# stuff we want with those is hard and a separate project/ticket. | |
# In the meantime -fno-sanitize-recover causes completely unrealted program | |
# halts during the very-early step, when building dependencies including | |
# capnp; some autotools configure.sh fails crazily, and nothing can work | |
# from that point on due to dependencies-install step failing. So at this | |
# time -fno-sanitize-recover is a no-go; it affects too much unrelated stuff. | |
# - It is more consistent/convenient to get all the bulky logs in one place as an | |
# artifact, rather than some in the pipeline output, others in the artifacts. | |
# (This preference is subjective, yes.) | |
# Here, as in all other tests below, we assemble a suppressions file in case this is a sanitized | |
# run; and we follow the procedure explained near setup-tests-env definition. To reiterate: to avoid | |
# tedium, but at the cost of mantainability of this file (meaning if a suppressions context is added then | |
# a few lines would need to be added here), we only list those contexts where *any* sanitizer has | |
# *any* suppression; otherwise we skip it for brevity. `find . -name 'suppressions*.cfg` is pretty useful | |
# to determine their presence in addition to whether the test itself has its specific suppressions of any kind. | |

# v<something>, at ~the same time (certainly within seconds of each other, empirically speaking). | |

# possibilities like it being unable to find the local file to upload and other stupidities); a change in API | |
# or some other behavior that was not handled by the upload-release-asset action package; possibly a break | |
# in a dependency of upload-release-asset (octokat?). upload-release-asset was last updated in 2020 and is | |
# officially now unmaintained. So I fought valiantly but eventually moved onto just using curl which worked | |
# almost immediately. Since the resulting code isn't even longer, and we are using a documented public API and | |
# standard tool (curl) which we also use elsewhere, it seemed a reasonable approach. TODO: Revisit perhaps. | |
