rapps.com will be launched when running 'rapps' from cmd or
from run, and since it is a console application, explorer/ cmd will
wait for it.
This rapps.com passes the commandline to rapps.exe,
and wait for rapps.exe to exit before closing.
CORE-17281
in favor of add_compile_options and the like with generator expressions
Also take this as an opportunity to remove the C++11 standard hack, GCC 8 now defaults to C++14
Instead of messing with global variables and the like, we introduce two target properties:
- WITH_CXX_EXCEPTIONS: if you want to use C++ exceptions
- WITH_CXX_RTTI: if you need RTTI in your module
You can use the newly introduced set_target_cpp_properties function, with WITH_EXCEPTIONS and WITH_RTTI arguments
We also introduce two libraries :
- cpprt: for C++ runtime routines
- cppstl: for the C++ standard template library
NB: On GCC, this requires to create imported libraries with the related built-in libraries:libsupc++, limingwex, libstdc++
Finally, we manage the relevant flags with the ad-hoc generator expressions
So, if you don't need exceptions, nor RTTI, nor use any runtime at all: you simply have nothing else to do than add your C++ file to your module
The formatter will select it anyway as soon as the partition size
permits it. We make it available internally however so as to "emulate"
FMIFS functionality.
Now rely on the partition filesystem for InstallVBRToPartition() instead
of the unreliable and deprecated partition type.
- Move the actual VBR bootcode installation helpers into fsutil.c
(they depend on the selected filesystem).
- Introduce InstallBootCodeToDisk() and InstallBootCodeToFile()
and bootcode.c helpers, in order to replace the several functions
that were duplicating the same code.
Fix filename completion that could cause a incorrect result when the path
contains "dots". (See also HBelusca@d12169b.)
See CORE-8623 and CORE-1901 (bug introduced in r25896 / 54cf74f).
For example:
- The current directory is `C:\Documents and Settings\Administrator\`, and you
input `".` and press TAB. The completion result would be `".Administrator"`,
which even does not exist.
- You input "some(file).ext", and you remove the final quote (or the quote
and "ext") and you attempt to complete the file name.
- Import two additional fixes from HBelusca@a826730: Fix the search ordering
in the comparisons between szSearch1, szSearch2 and szSearch3.

- Not all the wcscpy() / swprintf() calls have been converted to their
string-safe equivalents. Instead I used the string-safe functions only
for places where strings of unknown length were copied into fixed-size
internal buffers. On the contrary, for known-fixed-length strings being
copied or numbers being converted to string representations in large
enough buffers, I kept the original function calls.
- Verify the registry data that has been returned by NtQueryValueKey():
* When expecting (not multi) strings, check whether the data type is
either REG_SZ or REG_EXPAND_SZ.
* When expecting DWORD values, check whether the data type is
REG_DWORD and whether the data length is (greater or) equal to
sizeof(ULONG).
CORE-17050
Display the shutdown message popup dialog on the current input desktop,
and periodically monitor for any change of the input desktop. When the
latter changes, close the dialog and recreate it on the new input desktop.
In addition, retain the current dialog position and restore it when the
dialog is recreated on the new desktop.
CORE-17312
Hide everything under the same foreground & background colors, so that
the actual color and text blanking reset does not create a visual "blinking".
Then, blank the text and finally reset the actual foreground &
background colors.
We do this because we cannot do the screen scrolling trick that would
allow to change both the text and the colors at the same time (the
function is currently not available in our console "emulation" layer).
Dedicated to the hard work of Joachim Henze! xD
This reverts part of commit 043a98dd (see also commit b2aeafca).
Contrary to what I assumed in commit 043a98dd (and was also assumed in
the older commit b2aeafca), we cannot use the singled-linked lists to
queue and dequeue the PnP device-install events, because:
- the events must be treated from the oldest to the newest ones, for
consistency, otherwise this creates problems, as shown by e.g. CORE-16103;
- the system singled-linked lists only offer access to the top of the
list (like a stack) instead of to both the top and the bottom of the
list, as would be required for a queue. Using the SLISTs would mean
that only the newest-received events would be treated first, while the
oldest (which were the first received) events would be treated last,
and this is wrong.
Therefore one must use e.g. the standard doubly-linked list. Also, using
locked operations (insertion & removal) on the list of device-install
events is necessary, because these operations are done concurrently by
two different threads: PnpEventThread() and DeviceInstallThread().
Since the interlocked linked list functions are not available in user-mode,
we need to use instead locking access through e.g. a mutex.
- Move initialization of bc->raw_params also in BatchParams().
- The bc->raw_params, i.e. the unparsed batch/CALL parameters obtained
with %*, has any leading and trailing whitespace trimmed
(since Windows 2000+).
- Fail if no parameter is provided.
- The "CALL :label args..." syntax is available only when command extensions
are enabled. Fail if this syntax is used outside of a batch context.
- Reparse the CALL command parameter with the command parser, in order
to accurately parse and interpret it as a possible command (including
escape carets, etc...) and not duplicate the logic.
** CURRENT Windows' CMD-compatibility LIMITATION ** (may be lifted in
a "ROS-specific" running mode of CMD): only allow standard commands to
be specified as parameter of the CALL command.
This reparsing behaviour can be observed in Windows' CMD, by dumping
the interpreted commands after enabling the cmd!fDumpParse flag from
a debugger (using public symbols).
- When reparsing, we should tell the parser to NOT ignore lines that
start with a colon, because in this situation these are to be
considered as valid "commands" (for parsing "CALL :label").
* For Windows' CMD-compatibility, the remaining escape carets need to
be doubled again so that, after the new parser step, they are escaped
back to their original form. But then we also need to do it the "buggy"
way à la Windows, where carets in quotes are doubled either! However
when being re-parsed, since they are in quotes they remain doubled!!
(see "Phase 6" in https://stackoverflow.com/a/4095133/13530036 ).
* A MSCMD_CALL_QUIRKS define allows to disable this buggy behaviour,
and instead tell the parser to not not interpret the escape carets.
- When initializing a new batch context when the "CALL :label" syntax is
used, ensure that we reuse the same batch file position pointer as its
parent, so as to have correct call label ordering behaviour.
That is,
:label
ECHO hi
CALL :label
:label
ECHO bye
should display:
hi
bye
bye
i.e., the CALL calls the second label instead of the first one (and
thus entering into an infinite loop).
Finally, the "CALL :label" syntax strips the first ':' away, so, as a
side-effect, the command "CALL :EOF" fails (otherwise it would perform
a "GOTO :EOF" and succeeds), while "CALL ::EOF" succeeds.
Fixes some cmd_winetests.
All these modifications have been verified with Windows' CMD, either
by using written cmd_rostests and the existing cmd_winetests, or
manually by enabling the flags cmd!fDumpTokens and cmd!fDumpParse
(available in the public symbols) and analyzing how the tokens are
being parsed, as well as the generated command tree.

observations have to be double-checked in Windows' CMD!):

- Fix REM command parsing. A C_COMMAND-like structure should still
be built, so that it can show up during batch command echo. However
some specific handling needs to be done, so use instead a new C_REM
command type.
Escape carets are parsed differently than usual: they are explicitly
kept in the command line and don't participate in line continuations.
Also, the Windows' CMD behaviour is to discards everything before the
last line continuation.
- Prefix operator '@' (the "silent" operator) is parsed as a separate
command. Thus, the command @@foo@bar is parsed as: '@', '@', 'foo@bar'.
- Improve the checks for numbered redirection.
For this purpose, we check whether this is a number, that is in first
position in the current parsing buffer or is preceded by a whitespace-
like separator, including standard command operators (excepting '@' !)
and double-quotes.
- Empty command blocks, i.e. "( )", standing by themselves, or present
in IF or FOR commands, are considered invalid. (The closing parenthesis
is considered "unexpected".)
- Ignore single closing parenthesis when being outside of command blocks,
thus interpreting it as a command, and ignore explicitly everything
following on the same line, including line continuations.
This very specific situation can happen e.g. while running in batch mode,
when jumping to a label present inside a command block.
See the code for a thorough explanation.
- Detect whether a parenthesized block is not terminated at the end
of a command stream (getting a NUL character instead of a newline),
and if so, bail out early instead of entering into an infinite loop.
- Perform a similar check for the parenthesized list in FOR commands.
- Initialize the static 'InsideBlock' value to a known value.
- The '&' operator (multi-commmand) is allowed to have an empty RHS.
When such situation occurs, turn the CurrentTokenType to TOK_END
so as to avoid a parse error later on.
- The main body of a IF statement, or its 'else' clause, as well as
the main body of a FOR statement, must not be empty, otherwise this
is considered a syntax error. If so, call ParseError() that sets
the 'bParseError' flag, and forcing all batch execution to stop.
- Detect whether a division by zero is done, and fail if so.
- Detect whether an invalid number is provided:
* If _tcstol() fails with errno == ERANGE, we've got an overflow or
underflow.
* If the next character where _tcstol() is not a whitespace but is a
character compatible with the first character of an identifier, the
number is invalid.
- Add + to the list of existing unary operators (!,~,-), and parse them
where many of these are present. Indeed, expressions like: +3, -+-+3,
!!-+3 (or with other unary ops, etc.) are valid.
- Operators constituted of more than one characters, can contain
whitespace separating their constituting characters.
Thus, "a + = 3" is equivalent to "a += 3" (and the same for -=, *=,
/=, %=, &=, |= and ^=), and "a < < 3" is equivalent to "a << 3" (and
the same for >>, <<= and >>=).
- After evaluating everything, if unparsed data remains, fail and bail out.
- Return Windows' CMD-compatible errorlevels.
See https://ss64.com/nt/set.html for more details.
Fixes some cmd_winetests.
Observation shows that this is done only when the top-level batch file
is being run (and then terminates); the echo flag is not restored to its
previous state when a child batch file terminates and gives main back to
its parent batch.
- Make sure that non-administrator users can list associations, and
display appropriate error messages when e.g. they don't have sufficient
privileges to perform an operation.
- Make the helper functions all return Win32 values, used as the
ERRORVALUE, except when a specific extension association fails to be
displayed, in which case the ERRORVALUE is normalized to 1.
- Since the 'param' is a modifiable string (that can be modified by the
command, independently of the way it's called), just use it to isolate
the extension by zeroing out the equls-sign separator.
Commands APPEND/DPATH and FTYPE are also concerned by this; however
we do not implement them in our CMD.EXE yet.
These commands set the ERRORLEVEL differently, whether or not they are
run manually from the command-line/from a .BAT file, or from a .CMD file:
- From command-line/.BAT file, these commands set the ERRORLEVEL only if
an error occurs. So, if two commands are run consecutively and the first
one fails, the ERRORLEVEL will remain set even if the second command
succeeds.
- However, when being run from a .CMD file, these command will always
set the ERRORLEVEL. In the example case described above, the second
command that succeeds will reset the ERRORLEVEL to 0.
This behaviour is determined from the top-level batch/script file being
run. This means that, if a .BAT file is first started, then starts a
.CMD file, the commands will still behave the .BAT way; on the opposite,
if a .CMD file is first started, then starts a .BAT file, these commands
will still behave the .CMD way.
To implement this we introduce one global BATCH_TYPE enum variable that
is initialized to the corresponding batch/script file type when the
top-level script is loaded. It is reset to "none" when that script
terminates.
