Upstream version 6.02+dfsg

Adam Kaplan (28):
      Initial directory structure.
      Initial check-in. Note that this code is completely decrecated and 
probably fairly broken!  It is the oldest public release that I have, so I have 
uploaded it only as a benchmark of where the project started to measure how far 
it has come.  Get the next svn version!
      Version 1.11. Stable CPAN release.  Contains all changes from 0.02 
through 1.11
      Added HACKING file and updated MANIFEST accordingly
      Added links to svn repo @ google code
      Added test15p/x/v for perl <5.8.0 only and limited test06 to perl > 5.8
      Added and changed everything to pull the distribution 
      Attempted fix for RHEL platform where %f is handled differently (?)
      Fixed compile errors on 5.8.8
      Reverted Trunk to r13 because of too many major changes. Branched 
previous changes into sandbox at branches/tim.bunce
      SVN Keyword tests...
      SVN Keywords tests 2...
      Added svn property Id to all these files
      Fixed a bug in these scripts where the output directory was being checked 
      Changed "print OUT sprintf..." to less redundant "printf OUT ..."
      nytprofhtml - fixed module version variable
      Testing new svn alert list
      svn alert email list test attempt
      Failing to locate a source file after a best-effort attempt is no longer 
fatal (but will still whine)
      Updated changelog, Readme version and module version number
      Temporary patch -- Pause uses MakeMaker to determine versioning, and 
won't evaluate the 'required' version number. (All files that use the XS need 
to include its specific package version)
      - Added $VERSION to each module because the PAUSE indexer doesn't 
actually evaluation that
      Merged changes from the tim.bunce branch into the trunk.
      Added new header prototype to the html output for the invidual files. The 
output seemed overly bland.
      Added formatting to the subroutine link table:
      Removed link from the package name in the subroutine dispatch table 
(didn't make sense).
      Added ability to switch between any profile modes from any profile page.  
Current modes are 'block', 'line', and 'sub', however these can change 
arbitrarily without requirement any code in nytprofhtml to change. swapped backwards warning messages.

Chia-liang Kao (2):
      Make DB::enable_profile work after finish_profile is called.
      first cut of the nytoprof to cachegrind calltree output script.

Gisle Aas (36):
      There is no copyright and contact information at the bottom of the file.
      Make the --open option imply --html
      Just pass on --open to nyprofhtml.
      Improved test descriptions.
      Make ' 5' run all the <test05.*> tests
      Don't complain about passing *.pm and *.pl files to
      Add the attributes missing from expected test output in r526.
      Make 'nytprofhtml --open' work on machines that does not run Mac OS X.
      Document the nytprofhtml --open option.
      Use standard tabstop (ts=8) in all vim modelines.
      Rename as t/20.runtests.t
      No need to calculate the $diff twice in fmt_incl_excl_time
      Improve the Englishness of the prologue text
      Produce more readable timestamps in the code prologs.
      Make fmt_incl_excl_time not repeat the unit
      Failed to consistently convert '1 times' to 'once'.
      Sort the call locations by the time spent in the funtion as well as call 
      Simplify; $caller_filename same as $filename.
      Don't show filename for call refs to the same file.
      Cleanup; load_profile_data_from_file do need a filename argument
      Cleanup; Use named constant for TIME_BLOCK marker
      Make indentation in the documentation code samples consistent.
      Use consistent POD item lists
      Add Devel::NYTProf::Data::Raw module
      Incorporate Tim's explanations of the mystery chunks
      Use '#!/usr/bin/perl' lines for the scripts
      Let $. track the chunk sequence numbers
      Reuse the same SVs for each callback call.
      Rename ::Data::Raw as ::ReadStream as suggested by Tim
      Complete the rename to ::ReadStream.
      Doc tweaks; document the header attributes used.
      Oops - missing braces on if-block
      Improve portability to older perls; gv_fetchpvs() not supported in 5.8
      The timestamps in TAG_PID_{START,END} are NV
      Can't rely on #!-line to always work
      Avoid triggering "gcc internal compiler error"

Jan Dubois (18):
      Fix signed/unsigned mismatch
      Declarations must come before executable code (for MS VisualC)
      Hash keys length are only 32 bits while STRLEN may be 64
      An (unsigned long) is still only 32 bits on 64-bit Windows. %Ix prints 
the right number of bytes for size_t values for both 32 and 64 bit Windows.
      Declarations before executable code (plus a missing 'const')
      Use %p to format pointer values. Solves potential issue with Cygwin, 
which may define WIN32 symbol too but doesn't use MSVCRT.dll

inside the lexical scope!

      Add casts for 32/64 bit mismatches
      More 32/64-bit adjustments

      There shall be only one plan per test file
      Need string form of eval() to defer execution of use() until runtime
      #ifdef works on symbols, not expressions
      Use File::Spec->catfile() for portability
      Move context definition into higher scopes
      Use "%"IVdf instead of "%ld" for printing IV values

John P. Linderman (1):
      This changes only documentation, no testing should be required.

Joshua ben Jore (8):
      bin/nytprof* --help exits true
      prefer usage() to &usage because we're not using any magic

      Skipping tests this way because of the way 
      getcwd() on VMS returns VMS paths, these looks like u:[username], 
sticking a slash results in u:[username]/test.t and this is not a valid VMS 
filename, not inserting a slash results in only 4 out of 31 tests and 21 out of 
491 sub tests failing.  Getting there.
      Fixing previous VMS specific patch, compiler complains about invalid 
statement if VMS is defined, braces are required.
      Allow nytprof.out file to have 0 size on VMS as buffers have not flushed.
      Skip all fork() tests if on VMS
      This isn't pretty but it ensures the paths used are valid on VMS, 
previously they were an invalid mix of *nix and VMS.
      Filenames can have chars that are special regexp chars, escaping some I 
ran into on VMS.
      This is .js not .pl, the trailing comma caused a warning in MS IE
      Use quotemeta() to backslash non-'word' chars.
      On VMS fflush() does not fsync() to disk, have to skip this to avoid 
infinite loop.
      I didn't mean to add META.yml to the MANIFEST in my last change.
      Swap dot/period for underscore in outdir and new files to ensure is valid 
on VMS, skip test 14 and 60 as the expected profile data does not have VMS 
paths and will not match.  Now all tests pass on VMS.
      TIMTOWTDI and I agree \Q quote non-word characters till \E is neater.
      Yet Another VMS Fix, ODS-2 files are limited to 39.39 chars
      Trailing comma in .js causes warning in MS IE
