The cache part of this is specific to file-driver stores that are listed in tenancy.cache.stores, while tenancy.filesystem.scope_cache is set to true. The session part applies to the file session driver, while tenancy.filesystem.scope_sessions is set to true.

Ran into this while checking whether we could drop the separate 'parallel' cache store from our boilerplate's testing setup and instead just give the 'file' store a per-process path (framework/cache/data_<parallel testing token>), so each test process gets its own cache directory. Turns out scopeCache() discards configured paths entirely, so that has no effect (see below).

Using a different directory for the file cache store by setting cache.stores.file.path (either using config([...]), or directly in config/cache.php -- doesn't matter) has no effect -- FilesystemTenancyBootstrapper::scopeCache() ignores path/lock_path entirely and rewrites both to a hardcoded <storage>/framework/cache/data path on every tenancy()->initialize()/tenancy()->end():

// In `FilesystemTenancyBootstrapper::scopeCache()` (called both in `bootstrap()` and in `revert()`)
foreach ($stores as $name) {
    $path = $storagePath . '/framework/cache/data';
    $this->app['config']["cache.stores.{$name}.path"] = $path;
    $this->app['config']["cache.stores.{$name}.lock_path"] = $path;
    ...
}

Specific issues with hardcoding the path like this:

  • a store with a configured (non-default) path gets scoped to use the default one (what I described above)
  • lock_path is always overwritten with path, so a store with a separate lock directory loses that separation
  • revert() runs the same code, so it doesn't restore what the store was configured with before tenancy initialized -- it just re-applies the same hardcoded default. Central cache ends up using the wrong path after ending tenancy.

scopeSessions() has the same bug. It never reads session.files, it hardcodes <storage>/framework/sessions on both bootstrap and revert. So a configured session path gets discarded when tenancy initializes, and it doesn't get reverted back to what it was when tenancy ends. For example, with session.files set to /tmp/foo-sessions:

In tenant context:    session.files = .../storage/tenant<key>/framework/sessions
After ending tenancy: session.files = .../storage/framework/sessions

So after ending tenancy, sessions don't go back to the configured /tmp/foo-sessions. They use the hardcoded <storage>/framework/sessions path, which was never configured anywhere.

The fix

In bootstrap(), scopeCache() captures the original configured paths and scopes those instead of using a hardcoded default.

  • If the configured path is under the central storage path, that central part gets swapped for the tenant's storage path, keeping everything after it the same (e.g. storage/framework/cache/data becomes storage/tenant1/framework/cache/data).
  • If the path isn't storage_path()-based, there's nothing to swap, so the tenant's suffix just gets appended to the end of the path instead.

On revert(), scopeCache(false) puts the captured paths back into cache.stores.{$name}.path/lock_path and into the resolved store instance, so central cache uses the path it was configured with again.

The paths are captured just once, during scopeCache() at bootstrap(). If bootstrap() fails after scopeCache() (e.g. when scopeSessions() can't create its directory), revert() never runs and the config is left with the scoped paths, so capturing a second time would lose the central ones. Also, revert() iterates the stores whose paths were captured during bootstrap rather than config('tenancy.cache.stores'). Removing a store from that config in tenant context would otherwise make revert() skip it and leave it stuck with a tenant-scoped path, and adding one would make tenancy()->end() throw because its path was never captured (see the 'scopeCache ignores changes to tenancy.cache.stores made in tenant context' test). These are edge cases most users wouldn't notice, but still, worth mentioning.

lock_path stays null when a store doesn't configure it, rather than us making it default to the scoped path -- FileStore already falls back to path for locks in that case, so we can just respect the store's original config.

scopeSessions() does the same for session.files. It captures the configured path during bootstrap() (once, for the same reason as above), scopes it, and puts it back on revert() (the default storage/framework/sessions still ends up as storage/tenant1/framework/sessions, so nothing changes for the default config).

Also added tests that cover each of the issues above (+ a test for handling paths that aren't storage_path()-based, and one for a custom session.files path).

POSSIBLE MINOR BC: Someone with 'path' => '/var/cache/foobar' currently gets tenant cache in storage/tenant1/framework/cache/data. After this fix, they get /var/cache/foobar/tenant1, so whatever is already cached in the old directory is orphaned. The same applies to a non-default storage_path()-based path, e.g. 'path' => storage_path('framework/cache/data_' . env('TEST_TOKEN', 'default')). The config is now respected while scoping. The same goes for sessions -- with a non-default session.files, tenant sessions move from storage/tenant1/framework/sessions to the configured path scoped for the tenant, so the sessions in the old directory are orphaned.

Note about directory separators

While implementing a method that centralizes scoping a path to the tenant (tenantScopedPath()), we looked into which code should use DIRECTORY_SEPARATOR instead of plain / (for Windows compatibility, overall correctness and consistency).

In short, the separators only matter in code that compares paths -- there, both sides of the check have to use the same separators (it doesn't matter whether that's DIRECTORY_SEPARATOR or /). Strings that only get passed to the filesystem are fine with plain / -- the filesystem handles these just fine (for example, Laravel uses storage_path('framework/cache/data') as the default file cache store's path, and that works just fine on Windows).

A thing related to this are the rtrim() calls. In diskRoot()'s "disk present in tenancy.filesystem.disks, but not in tenancy.filesystem.root_override" code branch, rtrim() only trimmed the / separator. So if a Windows user used a local disk like that, and configured that disk's path to use a trailing separator, the method would set the disk root to a path like C:\app\uploads\/tenant1. In practice, this shouldn't be an issue, but trimming both / and \ prevents that code from setting the root to a weird path like that (so a very low impact change).

The tenantStoragePath() method got the same treatment as diskRoot() mentioned above: the original storage path could be configured with a trailing slash. Again, this was a non-issue, but only because the method's output didn't get compared to other strings in a way where this could be an issue. The rtrim there is a slight improvement, but primarily, this got changed for consistency with the change in diskRoot().

Summary by CodeRabbit

Bug Fixes

  • Improved isolation of file-based caches and sessions across tenant contexts.
  • Preserved central cache and session locations when switching contexts.
  • Scoped cache and lock directories independently, including custom paths.
  • Restored original cache and session settings after leaving a tenant context.
  • Avoided scoping unsupported, missing, or newly added cache stores.
  • Improved compatibility for custom filesystem paths across operating systems.

Tests

  • Expanded coverage for tenant isolation, custom directories, lock paths, session files, and restoration scenarios.

The tests cover the current (mostly incorrect) scopeCache() behavior (= hardcoding the /framework/cache/data path regardless of what was configured).

The 'file cache stores are separated per tenant' is not a regression test -- it covers the default path, which already worked correctly, there were just no tests for it. The rest are regression tests (see the "NOTE ABOUT REGRESSION" comments -- these are temporary, added them just so that it's clear what's currently wrong or broken) that should be fixed by the FS bootstrapper fix in the next commit.
scopeCache() rewrote path and lock_path for every file-driver store to a hardcoded '<storage>/framework/cache/data' path, completely ignoring the store's config. Now, scopeCache() remembers each store's original path and lock_path, scopes these paths for the tenant, and restores them to the stored originals on revert.

The store's lock_path was always overwritten by the same hardcoded path. But lock_path is configurable too, AND it's actually optional (unlike path). If it's not configured at all (= it's null or just unset), Laravel automatically falls back to the store's path. So in that case, leave lock_path null instead of assigning the path to it. This is not a *huge* change, assigning path to lock_path would essentially achieve the same thing, BUT if someone explicitly sets lock_path to null in the config, we should just respect that and let Laravel fall back to the path instead of setting the lock_path ourselves.

Also, on revert(), the same hardcoded path was used in scopeCache(). So if someone used a custom file driver-based store, cached something in central context, initialized and ended tenancy, the central cache got corrupt (see the 'central cache is not lost when tenancy ends' test).

📝 Walkthrough

Walkthrough

File cache stores now preserve original paths, apply tenant-specific path and lock_path values, update active FileStore instances, and restore paths after tenancy ends. Session paths reuse the same scoping logic. Tests cover isolation, restoration, dynamic stores, and external paths.

Merge Risk: 🟡 Moderate · up to 76597

This change scopes configured cache, lock, and session paths per tenant, but certain custom path forms may still resolve to a shared or unintended directory. That could weaken tenant data isolation for affected configurations, so these cases should be addressed before merge.

scopeCache() didn't feel right since it 1) stored thee original paths, 2) actually scoped things. Separate the concerns so that scopeCache() just does that -- scopes cache.

Also add a separate test ('scopeCache ignores changes to tenancy.cache.stores made in tenant context' ) -- the 'central cache is not lost when tenancy ends' covered the skipping mechanism partially, but having a separate test for the tenancy.cache.stores mid-tenant context changes is definitely cleaner and makes more sense.

Clear the cache-path snapshot after each revert.

$originalCachePaths and $originalCacheLockPaths remain populated after revert(). If central code changes a scoped store path or lock_path after tenancy ends, Line 211 skips the new values. The next bootstrap scopes and restores the stale first values.

Clear both maps after the revert loop. Add a regression test that changes both paths after tenancy()->end(), then initializes another tenant and verifies the new paths are scoped and restored.

Use a unique cross-platform temporary directory.

/tmp/tenancy-cache-test is shared by test workers. The cleanup can delete artifacts from another run or local data with the same path. The fixed /tmp path also prevents this test from running on platforms without /tmp.

The check could only pass with a `null` path, which is just bad configuration. So no reason to keep this.
Add more meaningful assertions, make the tests clearer (by improving the names, commnets and the test code itself), merge separate tests that don't need to be separate. Also, don't set lock_path in tests that don't deal with locks (except for the generic "file cache stores are separated per tenant" test where we just want to mirror Laravel's default file store config -- though note that keeping the lock_path unset or null there would make no difference).
Fails at :108 (= the bootstrap() behavior), the session path ends with framework/sessions instead of the configured framework/foo_session)). After commenting out  :108 and :110, it fails at :115 (= the revert() behavior, instead of reverting to the original configured path -- framework/foo_sessions -- it reverts to the hardcoded framework/sessions path)

Clear captured paths after revert.

FilesystemTenancyBootstrapper is a singleton, but these snapshots remain populated after scopeCache(false) and scopeSessions(false). If central configuration changes from path A to path B between tenant contexts, the next bootstrap still scopes path A and revert restores path A. This makes the new central paths ineffective and can direct cache or session I/O to obsolete directories.

Clear both cache maps and originalSessionPath after successful restoration, or create a fresh per-context snapshot. Add a regression that changes cache.stores.*.path and session.files between two tenant lifecycles.

Since the tests in question already delete the directories created at the hardcoded paths at their beginning, there was no point in keeping the trailing deletes. These only deleted the central dirs anyway, and we don't deal with that kind of cleanup in other tests.

Also update the stale comment in the 'a configured lock_path is scoped separately from path' test.

100-100: ⚠️ Potential issue | 🟡 Minor

Normalize the captured storage root before prefix comparisons.

tenantScopedPath() normalizes $configuredPath, but $this->originalStoragePath is stored without the same normalization. On Windows, a custom storage root containing / separators can fail the str_starts_with() check and send cache or session paths through the external-path branch.

Normalize the captured storage path once, or normalize both operands before comparing them. This repeats the unresolved finding from the previous review.

Since $originalRoot can be an OS path (with local disks without root_override) or a remote path/key (e.g. with S3 or FTP), we can't assume either separator while trimming. Trimming only '/' missed a trailing '\' on a Windows local root, so e.g. 'C:\app\uploads\' became 'C:\app\uploads\/tenant1'.

(The appended '/' stays as is -- it's accepted on Windows and it's the only correct separator for remote disks.)

Note that in practice, this wasn't an issue that could break anything. But assuming '/' in the rtrim code was incorrect.
Same as $configuredPath, $originalStoragePath isn't guaranteed to use OS separators either. On Windows, a storage path like 'C:/app/storage' would make the str_starts_with check return false even if true was expected.

Note that configuring the storage path to use '/' on Windows sounds very unlikely -- implementing this primarily for symmetry with $configuredPath.

Prevent .. segments from escaping the tenant directory.

When a cache or session path is /app/storage/../shared-cache, tenantScopedPath() returns /app/storage/tenant1/../shared-cache. Filesystem resolution maps this to /app/storage/shared-cache, so all tenants share the same directory. Canonicalize the path before replacing the storage prefix, or use the external-path branch for paths outside the central storage root. Add cache and session regressions.

…toragePath

Primarily making this change for consistency with diskRoot()'s usage of rtrim (`857c6fc`).

With the current Tenancy code, this doesn't fix any real issue, but if tenantStoragePath() got publicly exposed (like in #1479), in very rare cases, issues could arise. For example, when someone configures their storage path to end with a separator, comparing the result of tenantStoragePath() to other strings could behave unexpectedly without rtrim.

Since we discussed that normalizing directory separators is only needed for checks, is there a reason why we do things like this instead of just in the check itself?

I think on Windows this would end up turning all storage based paths such as storage_path('foo/bar') used in any config files to C://foo/bar unnecessarily when we could keep the original separators and that way intervene less.

It doesn't really matter for functionality but it seems to me we're doing more here than needed which even if it doesn't cause issues in the future could just make this code harder to understand.

Specifically I'm wondering if we could just do

if (str($configuredPath)->rtrim('/\\')->startsWith(rtrim($this->originalStoragePath, '/\\'))

or something similar.

If we also want to handle cases where storage_path() may be defined as foo/bar but then for whatever reason $configuredPath is foo\bar/baz then we can simply use replace() in the check instead of rtrim. But still don't see why we'd use the replaced/normalized strings for the actual value we return.

Good call. Fixed and updated the method in 1279451

If we also want to handle cases where storage_path() may be defined as foo/bar but then for whatever reason $configuredPath is foo\bar/baz then we can simply use replace() in the check ...

Though note that this case is not covered -- paths like this won't pass the str($configuredPath)->startsWith... check.

I'll see how exactly would the code that would treat this edge case look like, and let you know if I think it's worth dealing with at all

The code would then have to look like this:

$centralPath = rtrim($this->originalStoragePath, '/\\');
$normalize = fn (string $path) => str_replace('/', DIRECTORY_SEPARATOR, $path);

if (str($normalize($configuredPath))->startsWith($normalize($centralPath) . DIRECTORY_SEPARATOR)) {
    return str($configuredPath)
        ->substr(mb_strlen($centralPath))
        ->prepend($this->tenantStoragePath($suffix))
        ->toString();
}

So that's not a simple replace(), it brings back the normalization that I got rid in the commit linked above, and in the check's body, we have to work with the not-normalized path. I find that more complex than necessary, since the edge case you described seems very unlikely.

Since code like that would be problematic, we agreed that if there's no better solution here, we should just revert this function to its pre-127945190ee60cba00e81dbf6bab3133495428a3 state. The only trade-off there is that we'll be returning the normalized path.

Follow-up: 189c2b7

Instead of using the normalized path in the returned result, use the actual configured path (keeping its original separators).

The separator normalization got removed completely. Accepting either separator at the prefix boundary (`str($configuredPath)->startsWith([$centralPath . '/',
$centralPath . '\\'])`) covers what the normalization was there for, e.g. a path configured as `storage_path() . '/framework/foo_sessions'` while
`storage_path()` joins the segments with `\` on Windows.

Note that this does not cover the case where the configured path uses different separators than the original (central) path.
For example, `C:\app\storage\framework\cache` while `storage_path()` is `C:/app/storage`. A case like this would need a `replace()` in the check.

Reset captured paths after each tenant cycle.

FilesystemTenancyBootstrapper is a singleton. Tenant switches call revert() and then bootstrap() on the same instance. If central cache or session paths change between cycles, scopeCache() and scopeSessions() reuse stale snapshots and can restore stale paths. Clear all three snapshots after a successful revert. Add a two-cycle regression test with different central paths.

Revert the function to its pre-127945190ee60cba00e81dbf6bab3133495428a3 state. Even though in that state, we were returning the normalized path, which isn't correct, it handled the possible edge cases better (better than we could handle them with the proposed change of the version of this method before this commit anyway), and was overall more sound.
In the method, also deduplicate the separators. The only exception to this are Windows UNC paths, where the leading separators are intentionally '\\'.

Also, simplify tenantScopedPath() a bit. after + prepend can be replaced by just replaceFirst, and while returning in the second branch of the method, we don't need rtrim anymore (normalizePath() itself rtrims).

Comment thread src/Bootstrappers/FilesystemTenancyBootstrapper.php
Because str($foo)->deduplicate(...) returns null when $foo contains non-UTF-8 chars, normalizePath() would return just "". Now, the method returns the not-deduplicated, normalized path instead.

Duplicate: preserve tenant scoping when the storage root is /.

When originalStoragePath is /, normalizePath() produces an empty string. The prefix check then matches every absolute configured path. Laravel 12 and 13 return the subject unchanged when Str::replaceFirst() receives an empty search string. Therefore, cache and session paths remain central and are shared across tenants. (raw.githubusercontent.com)

Handle the root as a non-empty prefix, or build the tenant path from the relative portion. Add a regression for originalStoragePath === '/'.

270-274: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Duplicate: avoid adding a second UNC prefix on the fallback path.

On Windows, $uncPrefix is calculated before deduplicate(). For a UNC path containing invalid UTF-8, deduplication can return null; the fallback restores the original two leading separators, and Line 270 adds another separator. The resulting path has three leading separators and can break cache or session filesystem operations. (raw.githubusercontent.com)

Compute the prefix only when deduplication succeeds. Add a regression for an invalid UTF-8 UNC path.
