CORE-14096, CORE-8002
Patch based on an earlier fix attempt by Doug Lyons.
It should fix the problem observed by contributor 'whindsaks' in PR #5403.
This bug has always been present since the implementation of this feature
in commit a1eb1f6ba
(r40024).
The expansion of %~dpX ennhanced variables used to incorrectly show some
directories in uppercase. For example:
```batch
:: testcmd.cmd
echo '%~dp0'
echo '%~dps0'
echo '%~s0'
```
would show:
```
P:\Documents and Settings\Administrator\Desktop>echo 'P:\Documents and Settings\Administrator\DESKTOP\'
'P:\Documents and Settings\Administrator\DESKTOP\'
P:\Documents and Settings\Administrator\Desktop>echo 'P:\DOCUME~1\ADMINI~1\DESKTOP\'
'P:\DOCUME~1\ADMINI~1\DESKTOP\'
P:\Documents and Settings\Administrator\Desktop>echo 'P:\DOCUME~1\ADMINI~1\DESKTOP\testcmd.cmd'
'P:\DOCUME~1\ADMINI~1\DESKTOP\testcmd.cmd'
```
instead of the correct:
```
P:\Documents and Settings\Administrator\Desktop>echo 'P:\Documents and Settings\Administrator\Desktop\'
'P:\Documents and Settings\Administrator\Desktop\'
P:\Documents and Settings\Administrator\Desktop>echo 'P:\DOCUME~1\ADMINI~1\DESKTOP\'
'P:\DOCUME~1\ADMINI~1\DESKTOP\'
P:\Documents and Settings\Administrator\Desktop>echo 'P:\DOCUME~1\ADMINI~1\DESKTOP\testcmd.cmd'
'P:\DOCUME~1\ADMINI~1\DESKTOP\testcmd.cmd'
```
The reason was a wrong handling of the presence (or absence) of the
"short" path format specifier 's' in those enhanced variables.
In the examples above, the "Desktop" sub-directory has a short-path
name available (because it is in a FAT partition). The short-path name
was used some times also even with the 's' specifier absent.

|
|
* History:
|
|
*
|
|
* 17 Jun 1994 (Tim Norman)
|
|
* started.
|
|
*
|
|
* 08 Aug 1995 (Matt Rains)
|
|
* I have cleaned up the source code. changes now bring this source
|
|
* into guidelines for recommended programming practice.
|
|
*
|
|
* A added the the standard FreeDOS GNU licence test to the
|
|
* initialize() function.
|
|
*
|
|
* Started to replace puts() with printf(). this will help
|
|
* standardize output. please follow my lead.
|
|
*
|
|
* I have added some constants to help making changes easier.
|
|
*
|
|
* 15 Dec 1995 (Tim Norman)
|
|
* major rewrite of the code to make it more efficient and add
|
|
* redirection support (finally!)
|
|
*
|
|
* 06 Jan 1996 (Tim Norman)
|
|
* finished adding redirection support! Changed to use our own
|
|
* exec code (MUCH thanks to Svante Frey!!)
|
|
*
|
|
* 29 Jan 1996 (Tim Norman)
|
|
* added support for CHDIR, RMDIR, MKDIR, and ERASE, as per
|
|
* suggestion of Steffan Kaiser
|
|
*
|
|
* changed "file not found" error message to "bad command or
|
|
* filename" thanks to Dustin Norman for noticing that confusing
|
|
* message!
|
|
*
|
|
* changed the format to call internal commands (again) so that if
|
|
* they want to split their commands, they can do it themselves
|
|
* (none of the internal functions so far need that much power, anyway)
|
|
*
|
|
* 27 Aug 1996 (Tim Norman)
|
|
* added in support for Oliver Mueller's ALIAS command
|
|
*
|
|
* 14 Jun 1997 (Steffan Kaiser)
|
|
* added ctrl-break handling and error level
|
|
*
|
|
* 16 Jun 1998 (Rob Lake)
|
|
* Runs command.com if /P is specified in command line. Command.com
|
|
* also stays permanent. If /C is in the command line, starts the
|
|
* program next in the line.
|
|
*
|
|
* 21 Jun 1998 (Rob Lake)
|
|
* Fixed up /C so that arguments for the program
|
|
*
|
|
* 08-Jul-1998 (John P. Price)
|
|
* Now sets COMSPEC environment variable
|
|
* misc clean up and optimization
|
|
* added date and time commands
|
|
* changed to using spawnl instead of exec. exec does not copy the
|
|
* environment to the child process!
|
|
*
|
|
* 14 Jul 1998 (Hans B Pufal)
|
|
* Reorganised source to be more efficient and to more closely
|
|
* follow MS-DOS conventions. (eg %..% environment variable
|
|
* replacement works form command line as well as batch file.
|
|
*
|
|
* New organisation also properly support nested batch files.
|
|
*
|
|
* New command table structure is half way towards providing a
|
|
* system in which COMMAND will find out what internal commands
|
|
* are loaded
|
|
*
|
|
* 24 Jul 1998 (Hans B Pufal) [HBP_003]
|
|
* Fixed return value when called with /C option
|
|
*
|
|
* 27 Jul 1998 John P. Price
|
|
* added config.h include
|
|
*
|
|
* 28 Jul 1998 John P. Price
|
|
* added showcmds function to show commands and options available
|
|
*
|
|
* 07-Aug-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* Fixed carriage return output to better match MSDOS with echo
|
|
* on or off. (marked with "JPP 19980708")
|
|
*
|
|
* 07-Dec-1998 (Eric Kohl)
|
|
* First ReactOS release.
|
|
* Extended length of commandline buffers to 512.
|
|
*
|
|
* 13-Dec-1998 (Eric Kohl)
|
|
* Added COMSPEC environment variable.
|
|
* Added "/t" support (color) on cmd command line.
|
|
*
|
|
* 07-Jan-1999 (Eric Kohl)
|
|
* Added help text ("cmd /?").
|
|
*
|
|
* 25-Jan-1999 (Eric Kohl)
|
|
* Unicode and redirection safe!
|
|
* Fixed redirections and piping.
|
|
* Piping is based on temporary files, but basic support
|
|
* for anonymous pipes already exists.
|
|
*
|
|
* 27-Jan-1999 (Eric Kohl)
|
|
* Replaced spawnl() by CreateProcess().
|
|
*
|
|
* 22-Oct-1999 (Eric Kohl)
|
|
* Added break handler.
|
|
*
|
|
* 15-Dec-1999 (Eric Kohl)
|
|
* Fixed current directory
|
|
*
|
|
* 28-Dec-1999 (Eric Kohl)
|
|
* Restore window title after program/batch execution
|
|
*
|
|
* 03-Feb-2001 (Eric Kohl)
|
|
* Workaround because argc[0] is NULL under ReactOS
|
|
*
|
|
* 23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
|
|
* %envvar% replacement conflicted with for.
|
|
*
|
|
* 30-Apr-2004 (Filip Navara <xnavara@volny.cz>)
|
|
* Make MakeSureDirectoryPathExistsEx unicode safe.
|
|
*
|
|
* 28-Mai-2004
|
|
* Removed MakeSureDirectoryPathExistsEx.
|
|
* Use the current directory if GetTempPath fails.
|
|
*
|
|
* 12-Jul-2004 (Jens Collin <jens.collin@lakhei.com>)
|
|
* Added ShellExecute call when all else fails to be able to "launch" any file.
|
|
*
|
|
* 02-Apr-2005 (Magnus Olsen <magnus@greatlord.com>)
|
|
* Remove all hardcode string to En.rc
|
|
*
|
|
* 06-May-2005 (Klemens Friedl <frik85@gmail.com>)
|
|
* Add 'help' command (list all commands plus description)
|
|
*
|
|
* 06-jul-2005 (Magnus Olsen <magnus@greatlord.com>)
|
|
* translate '%errorlevel%' to the internal value.
|
|
* Add proper memory alloc ProcessInput, the error
|
|
* handling for memory handling need to be improve

* %~<modifiers><actual FOR variable character><other characters>

|
|
* characters are not part of the possible modifier characters, and
|
|
* are unrelated to the FOR variable (they can be part of a command).
|
|
* For example, if there is a %n variable, then out of %~anxnd,
|
|
* %~anxn will be substituted rather than just %~an.
|

*
|
|

|
|
* modifiers are 'dpn'. Parsing will first determine that 'dpnx'
|
|
* are modifiers, with the possible (last) valid variable being 'x',
|
|
* and will stop at the letter 'g'. Since 'g' is not a valid
|
|
* variable, then the actual variable is the lattest one 'x',
|
|
* and the modifiers are then actually 'dpn'.
|
|
* The FOR-loop will then display the %x variable formatted with 'dpn'
|
|
* and will append any other characters following, 'g'.
|
|
*
|
|
* C:\Temp>for %x in (foo.exe bar.txt) do @echo %~dpnxg
|
|
* C:\Temp\foog
|
|
* C:\Temp\barg
|
|
*
|
|
*
|
|
* 2. In this second example, the FOR variable character is 'g' and
|
|
* the actual modifiers are 'dpnx'. Parsing will determine also that
|
|
* the possible (last) valid variable could be 'x', but since it's
