BT_LOG_INIT_LOG_LEVEL() defines a hidden log level symbol and a static
constructor which initializes this symbol according to the value of
a given environment variable. This macro should be used in a module-wise
dedicated logging source file, `logging.c`, as such:

    #define BT_LOG_OUTPUT_LEVEL some_log_level_symbol
    #include <babeltrace/logging-internal.h>

    BT_LOG_INIT_LOG_LEVEL(some_log_level_symbol, "BABELTRACE_SOME_LOG_LEVEL");

BT_LOG_LEVEL_EXTERN_SYMBOL() declares this symbol as `extern`. It
should be used in a module-wise dedicated logging header, `logging.h`,
as such:

    #define BT_LOG_OUTPUT_LEVEL some_log_level_symbol
    #include <babeltrace/logging-internal.h>

Any module source file which contains log statements should use the
following lines **before any #include line**:

    #define BT_LOG_TAG "THE-MODULE-TAG"
    #include "logging.h"

If there are subdirectories within a module, it is possible that you
need to include "../logging.h" or "../../logging.h", for example. The
rule of thumb is that no module file, except `logging.c`, should include

ir: add BT_CTF_BYTE_ORDER_NONE and make it the default trace's native BO

There's a problem now where you need to explicitly set the native byte
order of a trace you create with bt_ctf_trace_create() with
bt_ctf_trace_set_native_byte_order() before the trace object is frozen,
otherwise the function which would cause the freezing fails.

Some trace formats have no byte order concept. Other properties like
alignment and binary field sizes may have no meaning either. Source
component classes which implement the decoding of those formats should
do a best effort to represent their trace's metadata using CTF IR. That
said, choosing an arbitrary trace's native byte order imposes this byte
order when a ctf.fs sink writes the trace. Here, BT_CTF_BYTE_ORDER_NONE
means that we don't care about the byte order, that it was not
meaningful when decoding the original trace, therefore you can choose
any output byte order you want.

With this patch, the initial trace's native byte order is
BT_CTF_BYTE_ORDER_NONE, and this is a valid byte order when the trace
needs to be frozen. A non-CTF writer trace cannot be used by a CTF
writer object anyway; a CTF writer always creates its own trace object.
The initial native byte order of a CTF writer trace is the machine's
byte order. You cannot set a CTF writer trace's native byte order to
BT_CTF_BYTE_ORDER_NONE. Also, you cannot set any field type's byte order
to BT_CTF_BYTE_ORDER_NONE: it's only valid for a non-CTF writer trace.

libctfcopytrace is modified to only explicitly set the CTF writer
trace's native byte order if the original trace's native byte order is
not BT_CTF_BYTE_ORDER_NONE.

6 years agoFix builds with built-in plugins
Philippe Proulx [Fri, 26 May 2017 23:24:13 +0000 (19:24 -0400)] 
Fix builds with built-in plugins

The recent convenience libraries are an issue for built-in plugins
because they lead to multiple definitions of the same symbols. This is
because we have to use --whole-archive when embedding the plugin
archives (.a), so the linker wants to embed all the symbols found. If
the same symbol is found twice, the linker is not happy.

For example: the `ctf` plugin's archive includes the symbols of
libbabeltrace-common.a. The CLI also includes the symbols of
libbabeltrace-common.a. When adding the `ctf` archive to the CLI with
--whole-archive, the symbols of libbabeltrace-common.a already exist in
the CLI, so we get the multiple definition error.

My solution here is to avoid adding the convenience libraries to the
individual plugins and to the library itself when BUILT_IN_PLUGINS is
true. The convenience libraries are added only one time to the CLI (in
cli/Makefile.am directly). When BUILT_IN_PLUGINS is false, it is
important to include the convenience library functions in each plugin
because they could be loaded outside the CLI, where those functions do
not exist.

There's also a fix to properly embed the Python plugin provider into the
library, and to print an error at configure time when
BUILT_IN_PYTHON_PLUGIN_SUPPORT=1 is used without
--enable-python-plugins.

Remove bt_graph_add_component_as_sibling()

This is not used anywhere, and it's one more thing to test. It remains
in the archives in case we need it in the future. This was created in
the days when it was expected that components would duplicate themselves
to share resources instead of dynamically adding ports like today.

This is the case of the null value singleton, bt_value_null, on which
you can call bt_get() and bt_put() and they should have no effect.
Before this patch, we can see log messages of the ref count going from 0
to 18446744073709551615 and other weird, huge values.
