Subject: [PATCH] libtraceevent: Handle parsing of "(REC)->" case
|
||||
|
||||
If a trace event wraps the special __entry variable to dereference it with
|
||||
parenthesis, it shows up in the trace event format file wrapping the
|
||||
"(REC)" as well. For example, the "func_repeats" event passed the __entry
|
||||
into a helper macro in the TP_printk() portion, and the macro correctly
|
||||
wrapped its parameter in parenthesis. This caused the output to show:
|
||||
|
||||
"(((u64)(REC)->top_delta_ts << 32) | (REC)->bottom_delta_ts)"
|
||||
|
||||
The parser then failed to parse the "(REC)->" portion, as it expected the
|
||||
"->" to appear directly after the "REC". This is not a requirement, and
|
||||
the parser should be able to handle such cases.
|
||||
|
||||
When this occurred, trace-cmd would error with the following message:
|
||||
|
||||
trace-cmd: No such file or directory
|
||||
Error: expected type 4 but read 5

Subject: [PATCH] libtraceevent: Move plugin_dir define logic to top level
|
||||
Makefile
|
||||
|
||||
The installation location of the plugin directory needs to be passed into
|
||||
the C files via the -DPLUGIN_DIR=".." compiler option. But the logic for
|
||||
that was only in the plugin directory, such that the main library did not
|
||||
know where to find the plugins (as the PLUGIN_DIR macro was not set). This
|
||||
caused the library not to load the plugins for the application.
|
||||
|
||||
By moving the logic to the top level Makefile and exporting the variables,
|
||||
this fixes the issue.
