libc/dbm: Differentiate between uninitialized and end-of-db cursors

2026-06-20T14:27:44+00:00

Commit `3a686b851f8f` fixed a `dbm_nextkey` edge case when using
the function after reaching the end of the database, but it inadvertently
broke the following `R_NEXT` behaviour:
"If the cursor is not yet set, this is the same as the R_FIRST flag."

Fix this by adding a new cursor constant that allows us to differentiate
between an unset cursor and a cursor that overflowed.

dbm_nextkey: Always return an error if we've reached the end of the database

2025-07-31T15:27:24+00:00

POSIX.1 states that `dbm_nextkey` must return an invalid key
(i.e., `key.dptr == NULL`) after the end of the database was reached.
The current implementation of `hash_seq` will incorrectly restart
the key sequence after the end of the database is reached.

Fix this by checking the "current bucket" index when R_NEXT is passed.

db/hash.c: Allow O_WRONLY in dbm_open

2025-07-30T09:31:16+00:00

The dbm(3) manpage explicitly states that O_WRONLY is not allowed in
dbm_open, but a more recent comment in ` __hash_open` suggests otherwise.
Furthermore, POSIX.1 allows O_WRONLY in dbm_open and states
that the underlying file must be opened for both reading and writing.

Fix this by correcting the O_WRONLY check and moving it further into
the function to make sure that the original flags are stored in hashp.
