It\nsplits the query string on [;\\n], and calls ddebug_exec_query() on\neach. All queries are processed independent of errors, allowing a\nquery to fail, for example when a module is not installed. Empty\nlines and comments are skipped. Errors are counted, and the last\nerror seen (negative) or the number of callsites found (0 or positive)\nis returned. Return code checks are altered accordingly.\n\nWith this, multiple queries can be given in ddebug_query, allowing\nmore selective enabling of callsites. As a side effect, a set of\ncommands can be batched in:\n\n\tcat cmd-file \u003e $DBGMT/dynamic_debug/control\n\nWe dont want a ddebug_query syntax error to kill the dynamic debug\nfacility, so dynamic_debug_init() zeros ddebug_exec_queries()\u0027s return\ncode after logging the appropriate message, so that ddebug tables are\npreserved and $DBGMT/dynamic_debug/control file is created. This\nwould be appropriate even without accepting multiple queries.\n\nThis patch also alters ddebug_change() to return number of callsites\nmatched (which typically is the same as number of callsites changed).\nddebug_exec_query() also returns the number found, or a negative value\nif theres a parse error on the query.\n\nSplitting on [;\\n] prevents their use in format-specs, but selecting\ncallsites on punctuation is brittle anyway, meaningful and selective\nsubstrings are more typical.\n\nNote: splitting queries on \u0027;\u0027 before handling trailing #comments\nmeans that a \u0027;\u0027 also terminates a comment, and text after the \u0027;\u0027 is\ntreated as another query. This trailing query will almost certainly\nresult in a parse error and thus have no effect other than the error\nmessage. The double corner case with unexpected results is:\n\n ddebug_query\u003d\"func foo +p # enable foo ; +p\"\n\nSigned-off-by: Jim Cromie \u003cjim.cromie@gmail.com\u003e\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "2b6783191da7211c88f98eb1a2bd2027bff36e30", "tree": "3227bbc5c9c187b6dbaa133a6f7e2e4364942594", "parents": [ "7281491c594e7b8501eb5dfcf6cd3724f8a1b5b0" ], "author": { "name": "Jim Cromie", "email": "jim.cromie@gmail.com", "time": "Mon Dec 19 17:13:12 2011 -0500" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Jan 24 12:48:55 2012 -0800" }, "message": "dynamic_debug: add trim_prefix() to provide source-root relative paths\n\ntrim_prefix(path) skips past the absolute source path root, and\nreturns the pointer to the relative path from there.
