LVM2 Test Suite
|
||||
===============
|
||||
|
||||
The codebase contains many tests in the test subdirectory.
|
||||
|
||||
Before running tests
|
||||
--------------------
|
||||
|
||||
Keep in mind the testsuite MUST run under root user.
|
||||
|
||||
It is recommended not to use LVM on the test machine, especially when running
|
||||
tests with udev (`make check_system`.)
|
||||
|
||||
You MUST disable (or mask) any LVM daemons:
|
||||
|
||||
- lvmetad
|
||||
- dmeventd
|
||||
- lvmpolld
|
||||
- lvmdbusd
|
||||
- lvmlockd
|
||||
- clvmd
|
||||
- cmirrord
|
||||
|
||||
For running cluster tests, we are using singlenode locking. Pass
|
||||
`--with-clvmd=singlenode` to configure.
|
||||
|
||||
NOTE: This is useful only for testing, and should not be used in produciton
|
||||
code.
|
||||
|
||||
To run D-Bus daemon tests, existing D-Bus session is required.
|
||||
|
||||
Running tests
|
||||
-------------
|
||||
|
||||
As root run:
|
||||
|
||||
make check
|
||||
|
||||
To run only tests matching a string:
|
||||
|
||||
make check T=test
|
||||
|
||||
To skip tests matching a string:
|
||||
|
||||
make check S=test
|
||||
|
||||
There are other targets and many environment variables can be used to tweak the
|
||||
testsuite - for full list and description run `make -C test help`.
|
||||
|
||||
Installing testsuite
|
||||
--------------------
|
||||
|
||||
It is possible to install and run a testsuite against installed LVM. Run the
|
||||
following:
|
||||
|
||||
make -C test install
|
||||
|
||||
Then lvm2-testsuite binary can be executed to test installed binaries.
|
||||
|
||||
See `lvm2-testsuite --help` for options. The same environment variables can be
|
||||
used as with `make check`.

# SYNOPSIS

|

# AX_GCC_BUILTIN(BUILTIN)
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro checks if the compiler supports one of GCC's built-in
|
||||
# functions; many other compilers also provide those same built-ins.
|
||||
#
|
||||
# The BUILTIN parameter is the name of the built-in function.
|
||||
#
|
||||
# If BUILTIN is supported define HAVE_<BUILTIN>. Keep in mind that since
|
||||
# builtins usually start with two underscores they will be copied over
|
||||
# into the HAVE_<BUILTIN> definition (e.g. HAVE___BUILTIN_EXPECT for
|
||||
# __builtin_expect()).
|
||||
#
|
||||
# The macro caches its result in the ax_cv_have_<BUILTIN> variable (e.g.
|
||||
# ax_cv_have___builtin_expect).
|
||||
#
|
||||
# The macro currently supports the following built-in functions:
|
||||
#
|
||||
# __builtin_assume_aligned
|
||||
# __builtin_bswap16
|
||||
# __builtin_bswap32

/*
|
||||
|
||||
CLVMD Cluster LVM daemon command processor.
|
||||
|
||||
To add commands to the daemon simply add a processor in do_command and return
|
||||
and messages back in buf and the length in *retlen. The initial value of
|
||||
buflen is the maximum size of the buffer. if buf is not large enough then it
|
||||
may be reallocated by the functions in here to a suitable size bearing in
|
||||
mind that anything larger than the passed-in size will have to be returned
|
||||
using the system LV and so performance will suffer.
|
||||
|
||||
The status return will be negated and passed back to the originating node.
|
||||
|
||||
pre- and post- command routines are called only on the local node. The
|
||||
purpose is primarily to get and release locks, though the pre- routine should
|
||||
also do any other local setups required by the command (if any) and can
|
||||
return a failure code that prevents the command from being distributed around
|
||||
the cluster
|
||||
|
||||
The pre- and post- routines are run in their own thread so can block as long
|
||||
they like, do_command is run in the main clvmd thread so should not block for
|
||||
too long. If the pre-command returns an error code (!=0) then the command
|
||||
will not be propogated around the cluster but the post-command WILL be called
|
||||
|
||||
Also note that the pre and post routine are *always* called on the local
|
||||
node, even if the command to be executed was only requested to run on a
|
||||
remote node. It may peek inside the client structure to check the status of
|
||||
the command.
|
||||
|
||||
The clients of the daemon must, naturally, understand the return messages and
|
||||
codes.
|
||||
|
||||
Routines in here may only READ the values in the client structure passed in
|
||||
apart from client->private which they are free to do what they like with.
