When a trace is static and we have seen the stream_end notification for
all the active streams, we can free the resources for handling the
trace.

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

    #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

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

    #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

Philippe Proulx [Tue, 30 May 2017 22:27:28 +0000 (18:27 -0400)] 
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

ctf plugins: prepend trace's hostname, if exists, to trace name

This makes the trace names a little more precise.

Note that as of this patch the visitor sets the trace's name just before
adding the first stream class, because after this, the trace is frozen
and we cannot set its name anymore. This is done as lately as possible
to increase our chance of having decoded the metadata's `env` block
(where the hostname is), if any. This can lead to an unnamed trace if
there's no stream classes. But if there's no stream classes, there can't
be any packet or event anyway, so there can't be any notification which
refers to this trace, so no other component should see the fact that
there's no name.

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.

6 years agoReplace all assert(false) and assert(0) with abort()
Philippe Proulx [Fri, 26 May 2017 05:02:18 +0000 (01:02 -0400)] 
Replace all assert(false) and assert(0) with abort()

Because assert() statements are not executed with a release/production
build, assert(false) and assert(0) statements are ignored and the
program's execution continues in an unexpected state. This could lead to
very weird and hard-to-debug situations, and potentially to corrupted
output traces.

Remove useless component/iterator validation functions

They only "validate" what we can assert anyway.
