-d38.9

Trace database map closings and appends Debug command-line switch

The -d38.9 debugging switch traces map closures for maps that can be closed:

ndbm_map_close(name, file, flags) 
db_map_close(name, file, flags) 
impl_map_close(name, file, flags) 
ph_map_close(name): pmap-ph_fastclose=num
prog_map_lookup(name) failed (errno) -- closing 
seq_map_close(name)

Here, the name is either the name you gave to the map with the K configuration command or one assigned internally by sendmail (such as aliases.files). The file is the filename on disk that contains the database. The flags describe the specific features of a map. They are printed in hexadecimal, and the meanings of the values printed are listed in Table 16-11.

MF_NODEFER

0x00020000

MF_REGEX_NOT

0x00040000

Regular expression negation (V8.9 and above)

MF_DEFER

0x00080000

Don't look up map in defer mode (V8.10 and above)

MF_SINGLEMATCH

0x00100000

MF_FILECLASS

0x00400000

Open failed, don't call map_close (V8.12 and above)

MF_CLOSING

0x01000000

In addition to tracing map closures, the -d38.9 debugging switch traces map appends allowed by the MF_APPEND flag (-A) as specified when the database is declared by the K configuration command:

ndbm_map_store append=new
db_map_store append=new

Here new is the new value appended to the old. Because this property is used for alias files, the new and old values have a comma inserted between them.
