.Sh DESCRIPTION
|
|
|
|
|
.Nm
|
|
|
|
|
is a command line tool to run the Taler exchange (HTTP server).
|
|
|
|
|
The required configuration, keys and database must exist before
|
|
|
|
|
running this command.
|
|
|
|
|
.Pp
|
|
|
|
|
Its options are as follows:
|
|
|
|
|
.Bl -tag -width indent
|
|
|
|
|
.It Fl C | -connection-close
|
|
|
|
|
Force each HTTP connection to be closed after each request (useful
|
|
|
|
|
in combination with
|
|
|
|
|
.Fl f
|
|
|
|
|
to avoid having to wait for nc to time out).
|
|
|
|
|
.It Fl c Ar FILENAME | Fl -config= Ns Ar FILENAME
|
|
|
|
|
Use the configuration and other resources for the merchant to operate
|
|
|
|
|
from FILENAME.
|
|
|
|
|
.It Fl h | -help
|
2016-03-01 15:35:04 +01:00
|
|
|
Print short help on options.
|
2019-05-10 12:56:49 +02:00
|
|
|
.It Fl i | -init-db
|
2017-01-13 14:44:51 +01:00
|
|
|
Initialize the database by creating tables and indices if necessary.
|
2019-05-10 12:56:49 +02:00
|
|
|
.It Fl v | -version
|
2016-03-01 15:35:04 +01:00
|
|
|
Print version information.
|
2019-05-10 12:56:49 +02:00
|
|
|
.It Fl f Ar FILENAME | Fl -file-input= Ns Ar FILENAME
|
|
|
|
|
This option is only available if the exchange was compiled with the
|
|
|
|
|
configure option --enable-developer-mode.
|
|
|
|
|
It is used for generating test cases against the exchange using AFL.
|
|
|
|
|
When this option is present, the HTTP server will
|
|
|
|
|
.Bl -enum -offset indent -compact
|
|
|
|
|
.It
|
|
|
|
|
terminate after the first client's HTTP connection is completed, and
|
|
|
|
|
.It
|
|
|
|
|
automatically start such a client using a helper process based on the
|
|
|
|
|
.Xr nc 1
|
|
|
|
|
or
|
|
|
|
|
.Xr ncat 1
|
|
|
|
|
binary using FILENAME as the standard input to the helper process.
|
|
|
|
|
.El
|
|
|
|
|
As a result, the process will effectively run with
|
|
|
|
|
.Ar FILENAME
|
|
|
|
|
as the input from an HTTP client and then immediately exit.
|
|
|
|
|
This is useful to test taler-exchange-httpd against many different
|
|
|
|
|
possible inputs in a controlled way.
|
|
|
|
|
.It Fl t Ar SECONDS | Fl -timeout= Ns Ar SECONDS
|
|
|
|
|
Specifies the number of SECONDS after which the HTTPD should
|
|
|
|
|
close (idle) HTTP connections.
|
|
|
|
|
.It Fl L Ar LOGLEVEL | Fl -loglevel= Ns Ar LOGLEVEL
|
|
|
|
|
Specifies the log level to use.
|
|
|
|
|
Accepted values are: DEBUG, INFO, WARNING, ERROR.
|
|
|
|
|
.El
|
|
|
|
|
.Sh SIGNALS
|
|
|
|
|
.Nm
|
|
|
|
|
responds to the following signals:
|
|
|
|
|
.Bl -tag -width indent
|
|
|
|
|
.It Dv SIGUSR1
|
|
|
|
|
Sending a SIGUSR1 to the process will cause it to reload denomination
|
|
|
|
|
and signing keys.
|
|
|
|
|
.It Dv SIGTERM
|
2016-05-31 18:58:59 +02:00
|
|
|
Sending a SIGTERM to the process will cause it to shutdown cleanly.
|
2019-05-10 12:56:49 +02:00
|
|
|
.It Dv SIGHUP
|
|
|
|
|
Sending a SIGHUP to the process will cause it to re-execute the
|
|
|
|
|
taler-exchange-httpd binary in the PATH, passing it the existing
|
|
|
|
|
listen socket.
|
|
|
|
|
Then the old server process will automatically exit after it is done
|
|
|
|
|
handling existing client connections; the new server process will
|
|
|
|
|
accept and handle new client connections.
