2023-01-03Only build debug infrastructure if DEBUG is definedAlan Coopersmith
It's only used when DEBUG is defined, so don't build it when we're not using it. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

Let's clean this up so I don't have to fight vim and git in removing them. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
2013-08-29Making sure that a copied string is always null-terminated (#66345).Benno Schulenberg
A more minimalistic and formally correct solution. This amends and extends the previous fix for bug #66345, fixing not just yyGetKeyName() but also yyGetString(). Signed-off-by: Benno Schulenberg <bensberg@justemail.net> Fixes a typo from cdcd552 (should be sizeof - 1, not sizeof -i). Code flows that i is at most sizeof(scanBuf) - 1, so last is not needed.

2013-07-18Always terminate the scanBuf string (#66345)Peter Hutterer
If a key name exceeds 4 characters, the content of scanBuf is not null-terminated, giving error messages like syntax error: line 7 of test.xkb last scanned symbol is: FOOBARm Errors encountered in test.xkb; not compiled. (last character of the preceding 'maximum' statement in this case) X.Org Bug 66345 <http://bugs.freedesktop.org/show_bug.cgi?id=66345> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2012-11-01Reset scan state when opening a new fileDaniel Stone
When we opened a new file after encountering a parse error, we weren't resetting our scan state, and continued to read out of the old buffer rather than that of the new file. Fixes a regression introduced in 9887842e ('Use fread() instead of getc()'). Test case: xkbcomp -lfhlpR "path/to/xkeyboard-config.git/symbols/*" The Makefiles in that tree would cause parse errors, the resulting directory file is incomplete (down from ~12000 to ~230 lines).

2011-12-28Make sure to leave room for trailing nil byte in yyGetNumberAlan Coopersmith
...though really, by the time you've added 1023 digits to the number you want to parse, you've got much bigger problems than an off-by-one error in your buffer count. Fixes parfait warnings: Buffer overflow (CWE 120): In array dereference of (*buf)[nInBuf] with index 'nInBuf' Array size is 1024 bytes, nInBuf >= 1 and nInBuf <= 1024 at line 625 of xkbscan.c in function 'yyGetNumber'. Buffer overflow (CWE 120): In array dereference of (*buf)[nInBuf] with index 'nInBuf' Array size is 1024 bytes, nInBuf <= 1025 at line 632 of xkbscan.c in function 'yyGetNumber'.

2010-07-12Fix signedness issue with getc() return valueJulien Cristau
getc() and ungetc() return and take, respectively, an int rather than a char to allow for error values as well. Oops. Signed-off-by: Daniel Stone <daniel@fooishbar.org>

2010-06-15Use fread() instead of getc()Daniel Stone
So, it turns out that if you're parsing a fairly large amount of data, using getc() to get all the input rather than, say, read(), is some kind of remarkably daft and unperformant idea. Signed-off-by: Daniel Stone <daniel@fooishbar.org>
2009-01-21Correct make distcheck and most gcc and sparse warnings.Paulo Cesar Pereira de Andrade
Remaining warnings are due to macros that check address or vectors on the stack and auto generated yacc code. Compiled with default flags and also as: % make CFLAGS=-DENTRY_TRACKING_ON -DDEBUG_ON -DASSERTIONS_ON to ensure the "simplification" of code like: foo.c: <hash>define DEBUG_VAR foo_VAR <hash>include "foo.h" ... foo.h: <hash>ifdef DEBUG_VAR_NOT_LOCAL extern <hash>endif int DEBUG_VAR; ... did not change the author's "intended" logic.
