OpenPlan

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:196

How the server should satisfy one open request with the core’s fixed flag-string vocabulary (r, r+, w, w+, wx, wx+, a, a+, ax, ax+).

readable/writable are the access the CLIENT asked for, which is not always what coreFlags grants: the core has no “create without truncating and without appending” and no write-only non-truncating mode, so those requests open a wider core descriptor and the broker enforces the requested access itself on every later read/write.

Properties

coreFlags

readonly coreFlags: string

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:198

The core flag string to try first.

---

fallbackFlags

readonly fallbackFlags: string | undefined

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:200

Used only when coreFlags fails with ENOENT — the create-without-truncate two-step.

---

follow

readonly follow: boolean

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:209

false for O_NOFOLLOW: a final component that IS a symbolic link must answer ELOOP.

---

readable

readonly readable: boolean

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:206

The access the client asked for, enforced by the broker on top of the core descriptor.

---

requireExisting

readonly requireExisting: boolean

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:204

No O_CREAT, but coreFlags would create: the server must prove the path exists first.

---

truncateFirst

readonly truncateFirst: boolean

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:202

O_TRUNC without O_CREAT: truncate the existing path to zero before opening.

---

writable

readonly writable: boolean

Defined in: packages/pgwasm/src/opfs/broker/protocol.ts:207
