seq.open - OPEN/CAESAR connection for traces encoded in the SEQUENCE
seq.open [seq_options] filename[.seq] [cc_options] prog[.a|.c|.o]
Taking as input the graph filename.seq
represents a set of one or more execution traces encoded in the simple
SEQUENCE format (see the exhibitor
manual page for a definition
of this format), and an OPEN/CAESAR program prog
an executable program prog
by performing appropriate calls to the C compiler.
According to the principles of the OPEN/CAESAR
architecture, prog is obtained by combining three different modules:
graph module is obtained by scanning filename.seq
- the storage module is
the standard OPEN/CAESAR library
- the exploration module is prog[.a|.c|.o]
seq.open tool was designed to handle very large execution traces, such as
those obtained by a random execution of a real system. For this reason,
seq.open works on-the-fly, without storing in memory the entire contents of
filename.seq. In order to speed up the exploration, an hash-based cache table
of bounded size is used to avoid multiple computations of label strings
and successor transitions.
] is supposed to contain an OPEN/CAESAR application program,
such as exhibitor
The exploration module can be
supplied in three different forms. It can be either an archive file (with
.a suffix), or a source C program (with .c suffix) or an object code file
(with .o suffix).
If prog.a is not present in the current directory, seq.open
attempts to fetch it in the OPEN/CAESAR binary library $CADP/bin.`arch`.
prog.c is not present in the current directory, seq.open attempts to fetch
it in the OPEN/CAESAR source library $CADP/src/open_caesar.
If prog.o is
not present in the current directory, seq.open attempts to fetch it in the
OPEN/CAESAR binary library $CADP/bin.`arch`.
If no suffix (.a, .c, .o) is specified
on the command line for the exploration module prog, seq.open will make
successive attempts to fetch this exploration module: first, as a source
C program with .c suffix; then as an archive file with .a suffix; finally
as an object code file with suffix .o.
the ``link mode'' of OPEN/CAESAR is supported by seq.open
if any, are passed to the C compiler.
The prog_options, if any, are passed
to prog. The following options seq_options are currently available:
- -seqno number
- Select the number-th sequence in filename.seq as the only sequence to be
considered during exploration. number should be a positive integer. By default
(if this option is not present on the command-line) or if seqno is equal
to zero, all sequences contained in filename.seq will be considered. If filename.seq
only contains a single sequence, using option `-seqno 1' may speed up the
execution by avoiding a preliminary scan of the sequence file.
- -cache number
- Select the size of the hash-based cache table used to avoid recomputations
of label strings and successor transitions. This size defines the number
of entries in the cache table. If number is not a prime, it will be replaced
by the closest higher prime number. By default (if this option is not present
on the command-line), the cache size will be 49999.
- Print statistics
about the usage of cache, such as the number of failures (the requested
data is not stored in the cache) and the number of successes (the requested
data is already in cache) every time a sink state is reached (i.e., at the
end of each sequence). Not a default option.
Exit status is 0
if everything is alright, 1 otherwise.
