Merge Risk: 🟡 Moderate · up to Concurrent tasks using the same SVN checkout may encounter missing or changing files during execution. Resolve or explicitly accept this risk before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The integration preserves existing project permissions and branch-override controls. However, a successful Subversion process does not necessarily mean the working copy is conflict-free, so reused workspaces may execute retained files rather than the intended revision. Production protection for plain Subversion connections also remains unconfirmed. Retained concerns

playbook and role files from the shared working copy before running svn update;
svn revert alone preserves them. Limit removal to those files so unrelated
unversioned files remain untouched.
Review comments at @db/Repository.go:
- Around line 96-98: Keep the shared working-copy path lock held in
updateAndCheckoutRepository through LocalExecutor.Run’s call to App.Run,
covering both repository updates and task execution so overlapping tasks cannot
change the revision during a run.

task a versioned tree path and pass that path to the task, rather than resolving
files through the shared GetFullPath() tree. Retain each generation while any
running task references it, and delete it only after the final referencing task
exits; keep the existing sync serialization.

Repositories with an svn:// or svn+ssh:// URL are served by a new SvnClient that shells out to the svn binary. git and Subversion repositories live on one server: the client is chosen per call from the repository URL, with no setting and no schema change. - The URL is the repository root and the branch is a path under it (trunk, branches/x, tags/y), so templates and tasks select an svn branch the way they select a git branch - The last revision that changed the branch path stands in for the commit hash; a task re-run checks out that revision - Route svn repositories in db_lib/repositoryTypeClient.go behind the unchanged CreateDefaultGitClient - Add pkg/svn validators, mirroring pkg/git; validate a task commit hash by the type of the template repository - Pass the password on stdin, never as an argument; use --no-auth-cache and --non-interactive; svn+ssh reuses the ssh command, agent and host configs of git - Accept svn and svn+ssh URLs in the repository form - Install subversion in the CI test job
Subversion repositories need the svn binary (1.10 or later for --password-from-stdin) wherever repositories are checked out.
svn prints the URL of a working copy canonicalized: scheme and host in lower case, without the default svnserve port 3690, percent-encoded and without a trailing slash. Compared verbatim, svn://host:3690/repo never matched, and every task checked the repository out again instead of updating it.
Commands get an environment without a locale. svn then wrote its
translated messages in a legacy encoding, which the task log showed as
replacement characters ("Mise � jour"), and on Linux it refuses to
check out a file whose name is not ASCII. Set LC_CTYPE=C.UTF-8 unless
LC_ALL, LC_CTYPE or LANG is configured.
A failed svn command returned its exit status alone, and the repository API, whose logger discards command output, logged "exit status 1" for every svn+ssh connection, path or credential problem. Add the end of svn's stderr to the error, with the userinfo of quoted URLs removed.
svn revert would unschedule a scheduled addition and leave its file behind. CanBePulled sees it in svn status and the working copy of the template is checked out again instead; cover that case.
svn status --quiet omits unversioned and ignored files, so a playbook or role a task generated in the working copy was kept by the update and could be picked up by the next task of the template. Pull now reverts local changes, then removes unversioned and ignored files with svn cleanup --remove-unversioned --remove-ignored, then updates. Reverting first also unschedules additions, whose files the cleanup then removes. Leftovers are removed in place instead of checking the working copy out again; a working copy svn cannot revert or clean makes Pull fail and is checked out again by the caller. Unlike git pull, untracked files are not kept.
Nothing a task of one template does in its working copy, nor another template's update, reaches the working copy of another template.
The playbook picker checks the branch out in a scratch directory and lists it with FindRepositoryFiles, which skips the .svn directory as it skips .git.

Adds Subversion repositories next to git ones. Revives #427 (multi-VCS support, closed in 2021 without a PR).
We run this branch in production: Semaphore is deployed in our infrastructure and runs our Ansible playbooks from an
svn+ssh://repository (~200 templates, ~4 GB working copy).How it works
svn://andsvn+ssh://repositories are served by a newSvnClientthat shells out to thesvnbinary (no maintained Go svn library), the wayCmdGitClientshells out togit. No setting, no schema change, no API change: git and Subversion repositories live on one server.CreateDefaultGitClientkeeps its signature and returns a small client that dispatches per call on the repository type (db_lib/repositoryTypeClient.go), so no call site changes.trunk,branches/x,tags/y). Templates and tasks select an svn branch exactly like a git branch (template/task overrides, branch dropdown, playbook browser), and the existingValidateGitBranchvalidates it (rejects.., leading-or/…).GetRemoteBranchesliststrunk,branches/*andtags/*.svn update -r N. The commit hash of a new task is validated by the type of the template's repository (Repository.ValidateCommitRef):pkg/gitis untouched; svn validators live in a newpkg/svn, mirroringpkg/git.Credentials and security
--password-from-stdin(never on the command line, visible inps), with--non-interactive --no-auth-cache.svn+ssh://: the repository's SSH key is loaded in Semaphore's ssh-agent andSVN_SSHgets the same ssh command asGIT_SSH_COMMAND(host key checking, project host configs).--, and a trailing@keeps an@in a path from being read as a peg revision. Revisions are digits only.LC_CTYPE=C.UTF-8unless a locale is configured; without one it wrote its messages in a legacy encoding and refuses non-ASCII file names on Linux.exit status 1.Working copies: one per template, as for git
Each template checks its branch out in its own working copy (
repository_<id>_template_<id>_<branch>_<hash>), exactly like a git working tree:svn revert -R .(local modifications;svn updatewould merge into them and report a conflict as success), thensvn cleanup --remove-unversioned --remove-ignored .(files a task left behind, scheduled additions, ignored files), thensvn update. Unlikegit pull, untracked files are not kept;The playbook picker browses an svn branch exactly like a git one: a scratch checkout (
CloneOrPull), listed byFindRepositoryFiles, which skips.svnas it skips.git.Earlier revisions of this branch shared one working copy per repository branch (then per-template trees of hard links, after the review) for a 4 GB repository. That repository is now under 100 MB; the branch was rebased on
developwithout that round trip and follows the git model, which is simpler and raises none of the cross-template concerns.Commits
Kept separate so they can be reviewed, dropped or split out:
feat(repository): add Subversion repository support: client, routing, validation, UI (repository form acceptssvn/svn+ssh), CI installssubversion.chore(docker): install subversion in server, runner and job images: without it the feature is unavailable in the official images.fix(svn)×4: found while testing on a real stand, in production and in review (URL canonicalization, locale, stderr, restoring the working copy before updating).test(svn)×3: scheduled additions, one working copy per template, browsing through a scratch checkout.The earlier
fix(api)commit (decrypt the repository key when browsing branches and playbooks) was dropped on rebase: #4298 fixed the same bug withdecryptKey. No API file is changed any more.Tests
