+# The tests in this file check that the following two bugs (both now fixed) |
+# do not reappear. |
+# |
+# jrnlmode2-1.*: Demonstrate bug #3745: |
+# |
+# In persistent journal mode, if: |
+# |
+# * There is a persistent journal in the file-system, AND |
+# * there exists a connection with a shared lock on the db file, |
+# |
+# then a second connection cannot open a read-transaction on the database. |
+# The reason is because while determining that the persistent-journal is |
+# not a hot-journal, SQLite currently grabs an exclusive lock on the |
+# database file. If this fails because another connection has a shared |
+# lock, then SQLITE_BUSY is returned to the user. |
+# |
+# jrnlmode2-2.*: Demonstrate bug #3751: |
+# |
+# If a connection is opened in SQLITE_OPEN_READONLY mode, the underlying |
+# unix file descriptor on the database file is opened in O_RDONLY mode. |
+# |
+# When SQLite queries the database file for the schema in order to compile |
+# the SELECT statement, it sees the empty journal in the file system, it |
+# attempts to obtain an exclusive lock on the database file (this is a |
+# bug). The attempt to obtain an exclusive (write) lock on a read-only file |
+# fails at the OS level. Under unix, fcntl() reports an EBADF - "Bad file |
+# descriptor" - error. |
