fix parsing of tags. make parse errors useful. add new tag tests.
old code read every head of .hgtags. delete and recreate of .hgtags gave
new head, but if error in deleted rev, .hgtags had error messages every
time it was parsed. this was very hard to fix, because deleted revs hard
to get back and update, needed merges too.
new code reads .hgtags on every head. advantage is if parse error
happens with new code, is possible to fix them by editing .hgtags on a
head and committing.
NOTE: new code uses binary search of manifest of each head to be fast,
but still much slower than old code. best thing would be to have delete
record stored in filelog so we never touch manifest. could find live
heads directly from filelog. this is more work than i want now.
new tests check for parse of tags on different heads, and inaccessible
heads created by delete and recreate of .hgtags.

INTRODUCTION # # This module provides coverage testing for Python code. # # The intended readership is all Python developers. # # This document is not confidential. # # See [GDR 2001-12-04a] for the command-line interface, programmatic # interface and limitations. See [GDR 2001-12-04b] for requirements and # design. """Usage: coverage.py -x MODULE.py [ARG1 ARG2 ...] Execute module, passing the given command-line arguments, collecting coverage data. coverage.py -e Erase collected coverage data. coverage.py -r [-m] [-o dir1,dir2,...] FILE1 FILE2 ... Report on the statement coverage for the given files. With the -m option, show line numbers of the statements that weren't executed. coverage.py -a [-d dir] [-o dir1,dir2,...] FILE1 FILE2 ... Make annotated copies of the given files, marking statements that are executed with > and statements that are missed with !. With the -d option, make the copies in that directory. Without the -d option, make each copy in the same directory as the original. -o dir,dir2,... Omit reporting or annotating files when their filename path starts with a directory listed in the omit list. e.g. python coverage.py -i -r -o c:\python23,lib\enthought\traits Coverage data is saved in the file .coverage by default.

IMPLEMENTATION # # This uses the "singleton" pattern. # # The word "morf" means a module object (from which the source file can # be deduced by suitable manipulation of the __file__ attribute) or a # filename. # # When we generate a coverage report we have to canonicalize every # filename in the coverage dictionary just in case it refers to the # module we are reporting on. It seems a shame to throw away this # information so the data in the coverage dictionary is transferred to # the 'cexecuted' dictionary under the canonical filenames. # # The coverage dictionary is called "c" and the trace function "t". The # reason for these short names is that Python looks up variables by name # at runtime and so execution time depends on the length of variables! # In the bottleneck of this application it's appropriate to abbreviate # names to increase speed. class StatementFindingAstVisitor(compiler.visitor.ASTVisitor): def __init__(self, statements, excluded, suite_spots): compiler.visitor.ASTVisitor.__init__(self) self.statements = statements self.excluded = excluded self.suite_spots = suite_spots self.excluding_suite = 0 def doRecursive(self, node): self.recordNodeLine(node) for n in node.getChildNodes(): self.dispatch(n) visitStmt = visitModule = doRecursive def doCode(self, node): if hasattr(node, 'decorators') and node.decorators: self.dispatch(node.decorators) self.doSuite(node, node.code) visitFunction = visitClass = doCode def getFirstLine(self, node): # Find the first line in the tree node. lineno = node.lineno for n in node.getChildNodes(): f = self.getFirstLine(n) if lineno and f: lineno = min(lineno, f) else: lineno = lineno or f return lineno def getLastLine(self, node): # Find the first line in the tree node. lineno = node.lineno for n in node.getChildNodes(): lineno = max(lineno, self.getLastLine(n)) return lineno def doStatement(self, node): self.recordLine(self.getFirstLine(node)) visitAssert = visitAssign = visitAssTuple = visitDiscard = visitPrint = \ visitPrintnl = visitRaise = visitSubscript = visitDecorators = \ doStatement def recordNodeLine(self, node): return self.recordLine(node.lineno) def recordLine(self, lineno): # Returns a bool, whether the line is included or excluded. if lineno: # Multi-line tests introducing suites have to get charged to their # keyword. if lineno in self.suite_spots: lineno = self.suite_spots[lineno][0] # If we're inside an exluded suite, record that this line was # excluded. if self.excluding_suite: self.excluded[lineno] = 1 return 0 # If this line is excluded, or suite_spots maps this line to # another line that is exlcuded, then we're excluded. elif self.excluded.has_key(lineno) or \ self.suite_spots.has_key(lineno) and \ self.excluded.has_key(self.suite_spots[lineno][1]): return 0 # Otherwise, this is an executable line. else: self.statements[lineno] = 1 return 1 return 0 default = recordNodeLine def recordAndDispatch(self, node): self.recordNodeLine(node) self.dispatch(node) def doSuite(self, intro, body, exclude=0): exsuite = self.excluding_suite if exclude or (intro and not self.recordNodeLine(intro)): self.excluding_suite = 1 self.recordAndDispatch(body) self.excluding_suite = exsuite def doPlainWordSuite(self, prevsuite, suite): # Finding the exclude lines for else's is tricky, because they aren't # present in the compiler parse tree.

DOCUMENT HISTORY # # 2001-12-04 GDR Created. # # 2001-12-06 GDR Added command-line interface and source code # annotation. # # 2001-12-09 GDR Moved design and interface to separate documents. # # 2001-12-10 GDR Open cache file as binary on Windows. Allow # simultaneous -e and -x, or -a and -r. # # 2001-12-12 GDR Added command-line help. Cache analysis so that it # only needs to be done once when you specify -a and -r. # # 2001-12-13 GDR Improved speed while recording. Portable between # Python 1.5.2 and 2.1.1. # # 2002-01-03 GDR Module-level functions work correctly. # # 2002-01-07 GDR Update sys.path when running a file with the -x option, # so that it matches the value the program would get if it were run on # its own. # # 2004-12-12 NMB Significant code changes. # - Finding executable statements has been rewritten so that docstrings and # other quirks of Python execution aren't mistakenly identified as missing # lines. # - Lines can be excluded from consideration, even entire suites of lines. # - The filesystem cache of covered lines can be disabled programmatically. # - Modernized the code. # # 2004-12-14 NMB Minor tweaks. Return 'analysis' to its original behavior # and add 'analysis2'. Add a global for 'annotate', and factor it, adding # 'annotate_file'. # # 2004-12-31 NMB Allow for keyword arguments in the module global functions. # Thanks, Allen. # # 2005-12-02 NMB Call threading.settrace so that all threads are measured. # Thanks Martin Fuzzey. Add a file argument to report so that reports can be # captured to a different destination. # # 2005-12-03 NMB coverage.py can now measure itself. # # 2005-12-04 NMB Adapted Greg Rogers' patch for using relative filenames, # and sorting and omitting files to report on. # # C.
