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. -# -# 2006-07-23 NMB Applied Joseph Tate's patch for function decorators. -# -# 2006-08-21 NMB Applied Sigve Tjora and Mark van der Wal's fixes for argument -# handling. -# -# 2006-08-22 NMB Applied Geoff Bache's parallel mode patch. -# -# 2006-08-23 NMB Refactorings to improve testability. Fixes to command-line -# logic for parallel mode and collect. -# -# 2006-08-25 NMB "#pragma: nocover" is excluded by default. -# -# 2006-09-10 NMB Properly ignore docstrings and other constant expressions that -# appear in the middle of a function, a problem reported by Tim Leslie. -# Minor changes to avoid lint warnings. -# -# 2006-09-17 NMB coverage.erase() shouldn't clobber the exclude regex. -# Change how parallel mode is invoked, and fix erase() so that it erases the -# cache when called programmatically. -# -# 2007-07-21 NMB In reports, ignore code executed from strings, since we can't -# do anything useful with it anyway. -# Better file handling on Linux, thanks Guillaume Chazarain. -# Better shell support on Windows, thanks Noel O'Boyle. -# Python 2.2 support maintained, thanks Catherine Proulx. -# -# 2007-07-22 NMB Python 2.5 now fully supported. The method of dealing with -# multi-line statements is now less sensitive to the exact line that Python -# reports during execution. Pass statements are handled specially so that their -# disappearance during execution won't throw off the measurement. -# -# 2007-07-23 NMB Now Python 2.5 is *really* fully supported: the body of the -# new with statement is counted as executable. -# -# 2007-07-29 NMB Better packaging. -# -# 2007-09-30 NMB Don't try to predict whether a file is Python source based on -# the extension. Extensionless files are often Pythons scripts. Instead, simply -# parse the file and catch the syntax errors. Hat tip to Ben Finney. -# -# 2008-05-25 NMB Open files in rU mode to avoid line ending craziness. -# Thanks, Edward Loper. -# -# 2008-09-14 NMB Add support for finding source files in eggs. -# Don't check for morf's being instances of ModuleType, instead use duck typing -# so that pseudo-modules can participate. Thanks, Imri Goldberg. -# Use os.realpath as part of the fixing of filenames so that symlinks won't -# confuse things. Thanks, Patrick Mezard. -# -# -# C.
