Support per UID buffers

This is a rather large commit. It adds the support for per UID buffers
for the user space tracer.

The --buffers-uid option is added to the lttng enable-channel command
which will set the session to use per UID buffers. So, all other channel
in that session MUST be set with the same buffer type or else an error
will be returned. For instance, here is an invalid use case:

$ lttng create
$ lttng enable-channel -u --buffers-uid chan1
$ lttng enable-channel -u chan2

The default is per PID (--buffers-pid). With no buffer type option, the
per PID is used for the UST tracer and global buffers for the kernel
being the only supported type for it (--buffers-global).

The tracing directory path are also changed to support this. For per UID
buffers, the path is now:

~/lttng-traces/ust/uid/1000/64-bit/*

For per PID buffers:

~/lttng-traces/<session_name>-<date>-<time>/ust/pid/ \
<app-name>-<pid>-<date>-<time>/

So basically, for UID, traces are stored per UID/ABI and for PID is
simply stored with the app name and pid. The kernel traces are untouched
and are still in kernel/.

Tests are also added for per UID buffers.

Deprecate enable/disable-consumer

The concept of consumer should change to the fact that a user can
enable/disable outputs such as file or network for streaming. We
envision that multiple outputs can be attached to a channel in the
future.

We want to minimise the amount of puzzlement for users. Having an error
message from the consumer daemon when --no-consumer has been specified
can be considered puzzling.

This calls for "add output" semantic, so we can support this "tee"
use-case seemlessly. We plan on allowing add/del output while tracing is
active, which is not currently permitted by enable-consumer.

Everything enable-consumer does can be done by lttng create options
Therefore, it seems easier for development of upcoming features and for
the sake of simplicity of interfaces to deprecate the current
enable/disable consumer.

This applies for both to the lttng UI commands and API calls. The
documentation has been removed from the man page and the help of the
lttng command. So, it exists but is simply not documented.

11 years agoMove LTTng-UST buffer ownership from application to consumer
David Goulet [Wed, 30 Jan 2013 21:36:23 +0000 (16:36 -0500)] 
Move LTTng-UST buffer ownership from application to consumer

Before this change, applications were performing allocation and teardown
of their buffers. Applications therefore had ownership of the buffers.
The shm and wait fd were passed from applications, though sessiond, to
consumerd through unix sockets.

This change moves ownership of buffers from applications to consumer.
This will allow sharing buffers across many processes in a near future.
It will also facilitate implementation of periodical timers on the
consumer side, now that it has ownership of channels and buffers (also
called streams). This imply that file descriptors on shm and wakeup end
of the pipe are now passed from the consumerd to sessiond, then to
applications, through unix sockets. Then, applications "map" channel and
streams into their own memory space. Channel control structure is
actually a copy for each application, while streams are a shared memory
map (shm) between consumerd and all applications that write into it, and
have a wake up file descriptor on the application side.

Dependency on libuuid has been added to lttng-tools, since the UUID is
needed at channel and buffer allocation.

Note that this is only for UST so the kernel buffers are still created
in the session daemon then passed to the consumer. There is basically no
change for the kernel other than adapting to the new communication data
structure.

This commit needs to be used along with commit named "Move LTTng-UST
buffer ownership from application to consumer" in lttng-ust.
