What this is

Since 9.15, standard (non-admin) users connecting to a pre-configured shared server (servers.json, shared: true) no longer see the server's tags, and no longer get its passfile connection parameter applied, and are prompted for a password instead. Admin users are unaffected.

Both have the same root cause: ServerModule.create_shared_server(), which materialises a standard user's own SharedServer copy of the owner's server, silently dropped fields that used to be copied verbatim, and the read-time overlay in get_shared_server() then kept them dropped.

Fixes #10136, fixes #10137.

Fix

  • create_shared_server(): tags is now copied from the owner's server like the other copied fields (bgcolor, fgcolor, service, etc.), and passfile is no longer stripped from connection_params.
  • get_shared_server(), where the per-user values are overlaid on the owner's server at read time: passfile is inherited from the owner unless the user's own row sets it, and tags fall back to the owner's when the SharedServer row has NULL tags. This reaches rows materialised since 9.15, which would otherwise have stayed broken; a user who has cleared every tag leaves an empty list rather than NULL, so that choice is still respected.
  • SENSITIVE_CONN_KEYS is renamed PER_USER_CONN_KEYS and now holds only the SSL certificate, key, CA and CRL paths.

The ownership/write boundary from #9830/#9835 is untouched: standard users still cannot edit the owner's Server row, they just read the same connection parameters an admin configured, which is what a shared server is for.

Test plan

  • Narrowed test_sanitizes_conn_params to the SSL-path keys it should actually strip, added test_copies_passfile and test_copies_tags, plus tests for existing SharedServer rows (inherited passfile, NULL tags falling back to the owner's, an empty tag list left alone).
  • --pkg browser.server_groups.servers.tests.test_shared_server_unit: 35/35 passed.
  • --pkg browser.server_groups.servers.tests: 126 passed, 1 pre-existing/unrelated skip.
  • pycodestyle clean.

Summary by CodeRabbit

  • Bug Fixes
    • Improved shared-server connection settings so password-file configuration is correctly inherited or preserved.
    • Preserved server-owner tags when shared-server tags are unset, while respecting explicitly cleared tags.
    • Ensured newly created shared-server connections retain applicable password-file settings and tags.

Walkthrough

Shared-server property handling now preserves inherited passfile values and owner tags. Explicit shared-server values, including empty tag lists, remain authoritative. Shared-server creation copies passfiles and tags while filtering only per-user SSL paths.

Changes

Shared-server property propagation

Layer / File(s) Summary
Shared-server property merging
web/pgadmin/browser/server_groups/servers/__init__.py, web/pgadmin/browser/server_groups/servers/tests/test_shared_server_unit.py
The merge path filters only per-user SSL paths. It inherits the owner passfile when absent, preserves a shared passfile, and falls back to owner tags only when shared tags are None. Tests cover these cases.
Shared-server creation copying
web/pgadmin/browser/server_groups/servers/__init__.py, web/pgadmin/browser/server_groups/servers/tests/test_shared_server_unit.py
Shared-server creation copies the owner passfile and tags. It removes only personal SSL certificate and key paths. Tests validate both copied properties and sanitization.

Estimated code review effort: 2 (Simple) | ~10 minutes

Suggested reviewers: asheshv

Merge Risk: 🔵 Low · up to 9d58f

Shared-server users will again receive the configured passfile and tags, but existing users may continue using an older passfile path after the owner rotates or revokes it until that old path is invalidated. The change is mergeable with explicit owner awareness and follow-up on passfile lifecycle behavior.

Two things done here.

The branch had never been rebased and was still stacked on five other commits, one of which is already upstream and the rest of which belong to #10313, #10314, #10315 and #10321, so the PR was showing fifteen changed files instead of its own two, and CodeRabbit had raised findings against code belonging to other PRs. It is now rebased onto current master, and I have carried those two findings over to #10315 and #10321 respectively rather than answering them here.

The remaining finding was about this change and was a fair one, so the fix has moved to where the values are read rather than only where the row is written. create_shared_server() only runs the first time a user opens a shared server, so anyone who has opened one since 9.15 already has a row with NULL tags and no passfile; worse, the overlay was actively deleting the owner's passfile from connection_params when the shared row had none. passfile is now out of the per-user set altogether (the constant is PER_USER_CONN_KEYS and holds only the SSL paths), and tags fall back to the owner's when the shared row is NULL, whilst an explicitly emptied list is left alone. Existing installations are correct on upgrade with no migration rewriting anyone's configuration.

Full Python suite passes locally.

…gadmin-org#10136, pgadmin-org#10137)

create_shared_server() started dropping tags (hardcoded to None) and
stripping passfile out of connection_params when materialising a
per-user SharedServer copy, a regression from the 9.15 data-isolation
hardening (9a76ed8, e4edcf2). Tags are now seeded from the owner's
server as with the other copied fields, and passfile - the mechanism
by which a shared server's owner lets every user authenticate
automatically - is excluded from the SSL-path stripping that still
rightly applies to sslcert/sslkey/sslrootcert/sslcrl/sslcrldir.
Copying tags and passfile in create_shared_server() only helps a user
who has not yet had a SharedServer row materialised for that server.
get_shared_server() creates one lazily and never revisits it, so anyone
who has opened a shared server since 9.15 already has a row with NULL
tags and no passfile, and would have stayed broken.

Both are therefore fixed where they are read rather than only where the
row is written.

passfile has come out of the per-user connection_params set entirely,
which is what it never should have been in: it is a file path, but it is
the owner's mechanism for letting every user of a shared server
authenticate without credentials of their own, so it is inherited like
any other connection parameter. The constant is renamed to
PER_USER_CONN_KEYS to say what it actually holds, which also removes the
'not in ... or k == passfile' special case the previous commit needed.

Tags fall back to the owner's when the SharedServer row has NULL, which
is a row predating the copy. A user who has removed every tag they had
leaves an empty list rather than NULL, so a deliberate choice is still
respected and the owner's tags do not come back.
