Issue
#3313concerns usable Windows x86 libraries. The workflow builds x86 Release and Debug configurations with the x86 MSVC environment. It runs the Windows test suite and packages the DLL, import library, public headers,rules_check.exe, and supporting files. It exposes the packages as run artifacts and uploads them to matching release tags. The CMake install rules provide the package layout.

Explanation
The changes support the Windows package objective. The workflow adds x86 and x64 builds, tests, dependency checks, checksums, artifacts, provenance attestations, and release uploads. The CMake changes add Release PDB generation and installation rules for the package contents. No unrelated product feature or public API change is shown.

version-tag ref, so manual workflow_dispatch runs can still build and test but
never publish, even when targeting a tag.

There was a problem hiding this comment.
Cache poisoning in the release build. This job builds the binaries we publish, but it restores ~/.conan2/p from actions/cache. A run triggered by a tag can restore caches saved on the default branch, so any default-branch run (for example a workflow_dispatch on v3/master) that saves a matching conan-Windows-… key can put modified pcre2/yajl/libcurl packages into the cache. They would then be linked statically into libModSecurity.dll and published. The tests would still pass and the .sha256 files are computed after the build, so nothing would catch it. zizmor reports this as cache-poisoning. I would drop the cache for release builds (see also the comment on the cache key).

Separately from the risk above, the cache rarely helps the runs that matter. A cache saved by a tag run is scoped to that tag, and the key includes the runner image version, which changes about weekly. A new v3.* tag can only read its own scope and the default branch, and this workflow never runs on v3/master pushes, so every release starts with a cold cache and the x86 jobs build everything from source (35–45 min). The "~10 min warm" figure only holds for repeated dispatch runs on one ref within the same image week. Removing the cache costs little and removes the risk.

There was a problem hiding this comment.
pip3 install conan --upgrade leaves the Conan version unpinned, and without a conan.lock the recipe revisions behind the binaries resolved with --build=missing are not pinned either. Two builds of the same tag can link different dependency versions, and a new Conan release can break a release build halfway. Could we pin Conan (pip install conan==2.x.y) and commit a lockfile used with --lockfile?

| # the DLL must not depend on anything beyond system DLLs and the VC++ runtime |
There was a problem hiding this comment.
The comment says the DLL must not depend on anything beyond system DLLs and the VC++ runtime, but dumpbin /dependents only prints the list. If a Conan default or recipe change makes a dependency shared, the DLL would import e.g. libcurl.dll or pcre2-8.dll. The tests would still pass, because those DLLs are in the build tree, while users would get "DLL not found" at load time. Could the step parse the output and fail on anything outside an allowlist (KERNEL32, WS2_32, IPHLPAPI, MSVCP140[D], VCRUNTIME140[D], api-ms-win-crt-*, ucrtbase[d], …)?

The zips are published with only an unsigned .sha256 next to them. The v3 source tarballs ship a GPG .asc, but anyone who can replace these release assets (the upload uses --clobber) can replace the hash too. Could we add actions/attest-build-provenance (needs id-token: write and attestations: write on this job), or sign the zips the same way as the tarballs?

v3.* also matches test and pre-release tags; the v3.0.99-test2 run on your fork created a draft release, and the same push here would leave stray drafts with binaries attached. Could the pattern be narrowed (e.g. v3.[0-9]+.[0-9]+), or publishing skipped for tags with a suffix?

The build, test-environment, jq test-disabling and ctest steps are copied from the build-windows job in ci_new.yml, and the description notes both lists now have to be kept in sync by hand. Moving them into a script (e.g. build/win32/run-tests.cmd) or a workflow_call reusable workflow used by both files would avoid release builds and CI drifting apart. Fine as a follow-up.

There was a problem hiding this comment.
This version is hard-coded and has already drifted once (3.0.14 while the headers said 3.0.17). The next tag will build with the old version in config.h unless someone remembers this file. Could it be read from headers/modsecurity/modsecurity.h with file(STRINGS …) and a regex instead? Either way, the bump is unrelated to the packaging change and would be better in its own commit.
There was a problem hiding this comment.
This version-maintenance issue is now addressed in #3653, in commit "84c76a1" (84c76a1).
The Windows CMake project version is derived from "MODSECURITY_MAJOR", "MODSECURITY_MINOR", and "MODSECURITY_PATCHLEVEL" in "headers/modsecurity/modsecurity.h", following the same approach used by "configure.ac".
The header is registered with "CMAKE_CONFIGURE_DEPENDS", so version changes trigger reconfiguration. The configuration also checks that each component has exactly one matching numeric definition. This keeps the project and package versions aligned with the source version without a separate manual version bump for each release.
When coordinating the two PRs, we can use that change to address the hard-coded version update here.

There was a problem hiding this comment.
The PDB is installed only for Debug and RelWithDebInfo, but the workflow ships Release, and MSVC Release builds do not link with /DEBUG, so the production packages have no symbols. A crash dump from the /MD Release DLL cannot be symbolized, and a rebuild will not give a matching PDB. Could the release packages be built as RelWithDebInfo (or with /Zi and /DEBUG), with the PDB shipped in the zip or a separate symbols zip?

Related: #3653 updates the Windows build path used here. It pins Conan and CMake in CI, replaces conanfile.txt with a Conan 2 Python recipe, and updates vcbuild.bat to use generated CMake presets and propagate build failures. It also includes the YAJL fix for CMake 4. |
Drop the Conan cache from the release build (cache poisoning), pin Conan, fail on DLL dependencies outside an allowlist, attest build provenance, publish only for v3.X.Y tags, and ship a PDB with the Release packages. Leave the project version in build/win32/CMakeLists.txt as it was; owasp-modsecurity#3653 replaces it with the version read from modsecurity.h.

Without the Conan cache, dependency sources are downloaded from their upstream hosts on every release run; git.openldap.org answered the parallel jobs with HTTP 429, and Conan gave up after 2 retries.

@coderabbitai Regarding the outside-diff comment on the tag filter in release-windows.yml (review 5620036724): this is not an issue. GitHub's filter patterns support + (one or more of the preceding character) and [0-9] character ranges. The "Filter pattern cheat sheet" in the workflow syntax docs lists v[12].[0-9]+.[0-9]+ as matching e.g. v1.10.1 or v2.0.0. The pattern has also triggered this workflow on my fork twice for the tag v3.0.99. Moving to v3.* with a failing validation step would turn suffixed test tags into red runs instead of skipped ones. |

Every package has a
.sha256file next to it and a build provenance attestation (gh attestation verify <zip> -R owasp-modsecurity/ModSecurity).Release builds are linked with
/DEBUG(plus/OPT:REF /OPT:ICF), so the Release packages ship a matching PDB as well, and crash dumps of the released DLL can be symbolized.Steps of the workflow:
