The wiki existed at https://code.google.com/p/crashpad/wiki, but given Google Code Project Hosting’s impending shutdown[1], it’s prudent to move wiki documents into the source code repository. This change moves the existing contents of doc into doc/support, to make way for documentation in doc. The two existing wiki pages, ProjectStatus and DevelopingCrashpad, are converted to AsciiDoc format (a fairly straightforward conversion) and checked in to doc. generate_asciidoc.sh is updated to produce HTML output from these files. The generated HTML will show up at http://docs.crashpad.googlecode.com/git/doc/. Note that generated HTML is still hosted on Google Code Project Hosting, but it’ll be easy to find a new home for them.

= on_demand_service_tool(1)
|
||
|
||
== Name
|
||
|
||
on_demand_service_tool - Load and unload on-demand Mach services registered with
|
||
launchd(8)
|
||
|
||
== Synopsis
|
||
|
||
[verse]
|
||
*on_demand_service_tool* *-L* *-l* 'LABEL' ['OPTION…'] 'COMMAND' ['ARG…']
|
||
*on_demand_service_tool* *-U* *-l* 'LABEL'
|
||
|
||
== Description
|
||
|
||
On-demand services may be registered with launchd(8) by using the *--load* form.
|
||
One or more service names may be registered with the bootstrap server by
|
||
specifying *--mach-service*. When a Mach message is sent to any of these
|
||
services, launchd(8) will invoke 'COMMAND' along with any arguments specified
|
||
('ARG…'). 'COMMAND' must be an absolute pathname.
|
||
|
||
The *--unload* form unregisters jobs registered with launchd(8).
|
||
|
||
== Options
|
||
|
||
*-L*, *--load*::
|
||
Registers a job with launchd(8). *--label*='LABEL' and 'COMMAND' are required.
|
||
This operation may also be referred to as “load” or “submit”.
|
||
|
||
*-U*, *--unload*::
|
||
Unregisters a job with launchd(8). *--label*='LABEL' is required. This operation
|
||
may also be referred to as “unload” or “remove”.
|
||
|
||
*-l*, *--label*='LABEL'::
|
||
'LABEL' is used as the job label to identify the job to launchd(8). 'LABEL' must
|
||
be unique within a launchd(8) context.
|
||
|
||
*-m*, *--mach-service*='SERVICE'::
|
||
In conjunction with *--load*, registers 'SERVICE' with the bootstrap server.
|
||
Clients will be able to obtain a send right by looking up the 'SERVICE' name
|
||
with the bootstrap server. When a message is sent to such a Mach port,
|
||
launchd(8) will invoke 'COMMAND' along with any arguments specified ('ARG…') if
|
||
it is not running. This forms the “on-demand” nature referenced by this tool’s
|
||
name. This option may appear zero, one, or more times. 'SERVICE' must be unique
|
||
within a bootstrap context.
|
||
|
||
*--help*::
|
||
Display help and exit.
|
||
|
||
*--version*::
|
||
Output version information and exit.
|
||
|
||
== Examples
|
||
|
||
Registers an on-demand server that will execute man_link:catch_exception_tool[1]
|
||
when a Mach message is sent to a Mach port obtained from the bootstrap server by
|
||
looking up the name +svc+:
|
||
[subs="quotes"]
|
||
----
|
||
$ *on_demand_service_tool --load --label=catch_exception \
|
||
--mach-service=svc \
|
||
$(which catch_exception_tool) --mach-service=svc \
|
||
--file=/tmp/out --persistent --timeout=0*
|
||
----

||
|

[subs="quotes"]
|
||
----
|
||
$ *on_demand_service_tool --unload --label=catch_exception*
|
||
----
|
||
|
||
== Exit Status
|
||
|
||
*0*::
|
||
Success.
|
||
|
||
*1*::
|
||
Failure, with a message printed to the standard error stream.
