When scanning directories and creating a list of all their content (filent.c) it would identify all the located files and folders using their long file names. On the other hand, referencing a target using its short file name inside a Jam script caused Boost Jam to reference those files twice using two separate TARGET structures - one identified using the file's short name and one using the file's long name. One bad example was the MkDir which would always attempt to create a folder identified by its short name even if that folder already existed (due to the NOUPDATE rule getting applied on the incorrect TARGET). The change does not affect targets whose names do not represent existing file names. Also, it seems to me that the short_path_to_long_path() call in file_dirscan() in the filent.c module should most likely be moved to file_info() in the filesys.c module. This would make mapping file names to file_info_t & TARGET structures consistent. However, I have not done this in this patch just to make the patch as minimal as possible. Prepared tests have been do nothing on non Windows platforms. [SVN r45144]

# Tests Boost Jam & Boost Build's source & target file name handling. Originally
|
|
# added as a regression test for a bug causing versions included in the Boost
|
|
# library 1.35 release (and earlier) not handling Windows short file names
|
|
# correctly. Also tests handling target file names containing spaces.
|
|
|
|
# Implementation notes:
|
|
#
|
|
# We expect Boost Jam to automatically update the 'all' target when no target
|
|
# has been explicitly specified on the command line.
|
|
#
|
|
# Windows short & long file names can not be matched until the file in
|
|
# question actually exists so we need to create the file before running Boost
|
|
# Jam.
|
|
#
|
|
# Currently Windows short file names are hardcoded but in case this proves
|
|
# insufficient we should use the GetShortPathName() Windows API to get the
|
|
# correct short file for a given long file name.
