doc: fate: Move documentation from .txt to .texi
The fate.txt file is ported to texinfo format. Therefore the fate.txt is renamed to fate.texi. The contents of the already existing fate.texi file are discarded. However there should be no loss of information. If you find anything missing, please report. Signed-off-by: Alexander Strasser <eclipse7@gmx.net> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

@chapter Introduction
|
||||
|
||||
FATE provides a regression testsuite embedded within the FFmpeg build system.
|
||||
It can be run locally and optionally configured to send reports to a web
|
||||
aggregator and viewer @url{http://fate.ffmpeg.org}.
|
||||
FATE is an extended regression suite on the client-side and a means
|
||||
for results aggregation and presentation on the server-side.
|
||||
|
||||
It is advised to run FATE before submitting patches to the current codebase
|
||||
and provide new tests when submitting patches to add additional features.
|
||||
The first part of this document explains how you can use FATE from
|
||||
your FFmpeg source directory to test your ffmpeg binary. The second
|
||||
part describes how you can run FATE to submit the results to FFmpeg's
|
||||
FATE server.
|
||||
|
||||
@chapter Running FATE
|
||||
In any way you can have a look at the publicly viewable FATE results
|
||||
by visiting this website:
|
||||
|
||||
@section Samples and References
|
||||
In order to run, FATE needs a large amount of data (samples and references)
|
||||
that is provided separately from the actual source distribution.
|
||||
@url{http://fate.ffmpeg.org/}
|
||||
|
||||
To inform the build system about the testsuite location, pass
|
||||
@option{--samples=<path to the samples>} to @command{configure} or set the
|
||||
@var{SAMPLES} Make variable or the @var{FATE_SAMPLES} environment variable
|
||||
to a suitable value.
|
||||
This is especially recommended for all people contributing source
|
||||
code to FFmpeg, as it can be seen if some test on some platform broke
|
||||
with there recent contribution. This usually happens on the platforms
|
||||
the developers could not test on.
|
||||
|
||||
The dataset is available through @command{rsync}, is possible to fetch
|
||||
the current sample using the straight rsync command or through a specific
|
||||
@ref{Makefile target}.
|
||||
The second part of this document describes how you can run FATE to
|
||||
submit your results to FFmpeg's FATE server. If you want to submit your
|
||||
results be sure to check that your combination of CPU, OS and compiler
|
||||
is not already listed on the above mentioned website.
|
||||
|
||||
In the third part you can find a comprehensive listing of FATE makefile
|
||||
targets and variables.
|
||||
|
||||
|
||||
@chapter Using FATE from your FFmpeg source directory
|
||||
|
||||
If you want to run FATE on your machine you need to have the samples
|
||||
in place. You can get the samples via the build target fate-rsync.
|
||||
Use this command from the top-level source directory:
|
||||
|
||||
@example
|
||||
# rsync -aL rsync://fate.ffmpeg.org/fate-suite/ fate-suite
|
||||
make fate-rsync SAMPLES=fate-suite/
|
||||
make fate SAMPLES=fate-suite/
|
||||
@end example
|
||||
|
||||
The above commands set the samples location by passing a makefile
|
||||
variable via command line. It is also possible to set the samples
|
||||
location at source configuration time by invoking configure with
|
||||
`--samples=<path to the samples directory>'. Afterwards you can
|
||||
invoke the makefile targets without setting the SAMPLES makefile
|
||||
variable. This is illustrated by the following commands:
|
||||
|
||||
@example
|
||||
# make fate-rsync SAMPLES=fate-suite
|
||||
./configure --samples=fate-suite/
|
||||
make fate-rsync
|
||||
make fate
|
||||
@end example
|
||||
|
||||
Yet another way to tell FATE about the location of the sample
|
||||
directory is by making sure the environment variable FATE_SAMPLES
|
||||
contains the path to your samples directory. This can be achieved
|
||||
by e.g. putting that variable in your shell profile or by setting
|
||||
it in your interactive session.
|
||||
|
||||
@chapter Manual Run
|
||||
FATE regression test can be run through @command{make}.
|
||||
Specific Makefile targets and Makefile variables are available:
|
||||
@example
|
||||
FATE_SAMPLES=fate-suite/ make fate
|
||||
@end example
|
||||
|
||||
@float NOTE
|
||||
Do not put a '~' character in the samples path to indicate a home
|
||||
directory. Because of shell nuances, this will cause FATE to fail.
|
||||
@end float
|
||||
|
||||
|
||||
@chapter Submitting the results to the FFmpeg result aggregation server
|
||||
|
||||
To submit your results to the server you should run fate through the
|
||||
shell script tests/fate.sh from the FFmpeg sources. This script needs
|
||||
to be invoked with a configuration file as its first argument.
|
||||
|
||||
@example
|
||||
tests/fate.sh /path/to/fate_config
|
||||
@end example
|
||||
|
||||
A configuration file template with comments describing the individual
|
||||
configuration variables can be found at @file{tests/fate_config.sh.template}.
|
||||
|
||||
@ifhtml
|
||||
The mentioned configuration template is also available here:
|
||||
@verbatiminclude ../tests/fate_config.sh.template
|
||||
@end ifhtml
|
||||
|
||||
Create a configuration that suits your needs, based on the configuration
|
||||
template. The `slot' configuration variable can be any string that is not
|
||||
yet used, but it is suggested that you name it adhering to the following
|
||||
pattern <arch>-<os>-<compiler>-<compiler version>. The configuration file
|
||||
itself will be sourced in a shell script, therefore all shell features may
|
||||
be used. This enables you to setup the environment as you need it for your
|
||||
build.
|
||||
|
||||
For your first test runs the `fate_recv' variable should be empty or
|
||||
commented out. This will run everything as normal except that it will omit
|
||||
the submission of the results to the server. The following files should be
|
||||
present in $workdir as specified in the configuration file:
|
||||
|
||||
@itemize
|
||||
@item configure.log
|
||||
@item compile.log
|
||||
@item test.log
|
||||
@item report
|
||||
@item version
|
||||
@end itemize
|
||||
|
||||
When you have everything working properly you can create an SSH key and
|
||||
send its public part to the FATE server administrator.
|
||||
|
||||
Configure your SSH client to use public key authentication with that key
|
||||
when connecting to the FATE server. Also do not forget to check the identity
|
||||
of the server and to accept its host key. This can usually be achieved by
|
||||
running your SSH client manually and killing it after you accepted the key.
|
||||
The FATE server's fingerprint is:
|
||||
|
||||
b1:31:c8:79:3f:04:1d:f8:f2:23:26:5a:fd:55:fa:92
|
||||
|
||||
The only thing left is to automate the execution of the fate.sh script and
|
||||
the synchronisation of the samples directory.

||||

||||

@section Testing Profiles
|
||||
The configuration file passed to @command{fate.sh} is shell scripts as well.
|
||||
|
||||
It must provide at least a @var{slot} identifier, the @var{repo} from
|
||||
which fetch the sources, the @var{samples} directory, a @var{workdir} with
|
||||
enough space to build and run all the tests.
|
||||
Optional submit command @var{fate_recv} and a @var{comment} to describe
|
||||
the testing profile are available.
|
||||
|
||||
Additional optional parameter to tune the FFmpeg building and reporting process
|
||||
can be passed.
|
||||
|
||||
@example
|
||||
slot= # some unique identifier
|
||||
repo=git://source.ffmpeg.org/ffmpeg.git # the source repository
|
||||
samples=/path/to/fate/samples
|

--------------------------------------
|

fate-list
|
||||
Will list all fate/regression test targets.
|
||||
|
||||
fate
|
||||
Run the FATE test suite (requires the fate-suite dataset).
|
||||
|
||||
FATE Makefile variables:
|
||||
|
||||
V
|
||||
Verbosity level, can be set to 0, 1 or 2.
|
||||
* 0: show just the test arguments
|
||||
* 1: show just the command used in the test
|
||||
* 2: show everything
|
||||
|
||||
SAMPLES
|
||||
Specify or override the path to the FATE samples at make time, it has a
|
||||
meaning only while running the regression tests.
|
||||
|
||||
THREADS
|
||||
Specify how many threads to use while running regression tests, it is
|
||||
quite useful to detect thread-related regressions.
|
||||
|
||||
Example:
|
||||
make V=1 SAMPLES=/var/fate/samples THREADS=2 fate
