* LexerParser: Regenerate parser files with GNU Bison 3.7.4Christoph Grüninger2021-01-258-3658/+3969
| | | | Adjust expected test output.
* LexerParser: Manual removing code from Bison is no longer neededChristoph Grüninger2021-01-254-11/+0
| | | | | This was needed to avoid warnings while compiling the sources generated by older versions of GNU Bison, but is not with GNU Bison 3.7.4.
* LexerParser: Do not use GNU Bison's yacc mode, we use Bison extensionsChristoph Grüninger2021-01-254-4/+4
| | | | Silence Bison warnings regarding use of Bison extensions.
* cmGccDepfileReader: Rework helper codeKyle Edwards2020-10-132-2/+2
| | | | | Fix some of the semantics of the depfile, add error handling, and refactor cmGccDepfileLexerHelper.
* cmCommandArgumentParserHelper: rework input handlingOleksandr Koval2020-09-092-19/+10
| | | | | | | | Old implementation uses involved Flex input management technique that requires usage of obsolete YY_INPUT macro. This causes a lot of useless allocations and byte-by-byte scanning. New implementation avoids those hacks, it uses yy_scan_string() API to setup Flex input. Also it fixes reporting of syntax error position and corresponding tests.
* cmake_command: Add command to EVAL a CMake script as a stringCristian Adam2020-03-032-22/+6

* Add a parser for GCC-style depfilesJoerg Bornemann2020-01-284-0/+2971
| | | | | | | | | | | Introduce the function cmReadGccDepfile that parses a GCC-style depfile and returns its content. The implementation uses a lexer that is modeled after the re2c implementation in Ninja. The sample files of the autotest have been created with gcc 8.3.0. This depfile reader is to be used by the Autogen facility to make use of the depfiles that are generated by Qt's meta object compiler.

* cmListFileLexer: Add missing include to avoid possible pointer truncationZsolt Parragi2019-02-132-2/+2
| | | | | | | The `cmsys/Enconding.h` include had a typo in its surrounding ifdef, possibly causing a missing function declaration (`cmsysEncoding_DupToWide`). As this is C code, this resulted in the code compiling, but with a truncated return value, possibly causing crashes.
* Fix most clang -Wextra-semi-stmt warnings in C++ filesSean McBride2019-01-1512-12/+12
| | | | Suppress one in code generated by flex.
* Source/LexerParser: Suppress "Use of zero-allocated memory" warningKyle Edwards2019-01-148-0/+40
| | | | | | | clang scan-build warns about YY_CURRENT_BUFFER_LVALUE being zero- allocated, but the whole point of the macro is to know that it's not zero. Wrap the entire file in an "#ifndef __clang_analyzer__" block in order to suppress the warning.
* Fortran: Fix module dependency scanning with upper-case SUBMODULEBrad King2018-11-202-114/+114
| | | | | | | | The lexical token expression added by commit v3.7.0-rc1~73^2~1 (Fortran: Add support for submodule syntax in dependency scanning, 2016-09-05) has a typo and does not match upper-case `B` in `SUBMODULE`. Fix it. Fixes: #18595
* LexerParser: Suppress GCC -Wconversion warningsBrad King2018-07-319-880/+904
| | | | | GCC 8 warns about some of the conversions in bison-generated code. Suppress the warnings.
* math: Restore toleration of unexpected characters in an expressionBrad King2018-07-165-73/+67
| | | | | | | | Prior to commit 7c4c13ffef (math: Reject unexpected expression input explicitly, 2018-05-18) we ignored unexpected characters in an expression that otherwise can be parsed. In order to preserve compatibility with projects that accidentally used this, convert the error to a warning.

* | ListFileLexer: Do not match null bytes in inputBrad King2018-06-262-103/+99
|/ | | | | | | | | | | Extend the fix from commit v3.10.0-rc1~188^2 (ListFileLexer: fix heap-buffer-overflow on malicious input, 2017-08-26) to apply to all lexer token matches. Replace all `.` with `[^\0\n]`. Update all `[^...]` match expressions to not match `\0`. We cannot safely process null bytes in strings. Fixes: #18124
* Fortran: Add support for submodule dependenciesBrad King2018-04-202-4/+4
| | | | | | | | | | | | | | | | | | | | | Since commit v3.7.0-rc1~73^2~1 (Fortran: Add support for submodule syntax in dependency scanning, 2016-09-05) we support parsing Fortran sources that use submodule syntax, but it left addition of `.smod` dependencies to future work. Add it now. The syntax submodule (module_name) submodule_name means the current source requires `module_name.mod` and provides `module_name@submodule_name.smod`. The syntax submodule (module_name:submodule_name) nested_submodule_name means the current source requires `module_name@submodule_name.smod` provides `module_name@nested_submodule_name.smod`. Fixes: #17017

* ListFileLexer: fix heap-buffer-overflow on malicious inputMatthias Maennich2017-08-302-98/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | In case a list file contains a null terminated string that is continued until a later space, the lexer token information got inconsistent: e.g. an argument "TEST\0FOOBAR" is passed by the lexer as a token char* = "TEST\0FOOBAR" and length 11 ^^ note: ascii 0x00 Using strdup in cmListFileLexer leads lexer->token.text to be allocated with size 5 and lexer->token.length to be set to 11 A subsequent call to this function with an argument of 5 < length <= 11 wrongly assumed a sufficiently sized buffer and therefore corrupted the heap buffer. The program might crash due to this corruption. The case "NullTerminatedArgument" is intentionally using a quite large 'rest' to increase the chance to actually hit the issue. It will reliably crash with address sanitizer enabled though. This fix addresses all rules where arbitrary characters are matched to ignore \0 in order to fall through to the rule that matches an arbitrary character as BadCharacter.

* cmFortranLexer: regenerate with flex 2.6.4 (previously 2.6.1)Matthias Maennich2017-08-283-497/+950
| | | | | | | | | | | | | | | | | | | | | | | | flex 2.6.3 introduces symbol remapping through macro definitions. hence the change appears bigger than one would expect from a minor version upgrade. In addition some manual cleanup that had to be done previously is now obsolete. namely: - the size_t cast of _yybytes_len in yy_scan_bytes (i is now also defined int and not size_t anymore) - the redefinition of yyl within yy_find_action (yyl is now already defined as int) Line number preprocessor directives (#line) were previously generated into the c source file. This actually breaks debugging as debuggers have a hard time finding the original cmFortranLexer.in.l and mapping the current instruction to a meaningful location within that file. The prefix "cmFortran_yy" can already be set as %option directly. For convenience also provide a sed command for all the manual steps that need to be done after generating.
