* Replace Cactus complex number type with C/C++ complex numberseschnett2013-03-08
| | | | | | | | | | | | | | | | Map CCTK_COMPLEX to "double complex" in C, and "complex<double>" in C++. (It is already mapped to "double complex" in Fortran.) Update type definitions. Re-implement Cactus complex number math functions by calling the respective C functions. Update thorn that access real and imaginary parts of complex numbers to use standard-conforming methods instead. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4979 17b73243-c579-4c4c-a9d2-2d5706c11dac

* ParseFile.c: Change semantics of call to fread so that error check makes sensehinder2012-11-20
| | | | | | fread takes an "item size" and a "number of items" and returns the number of items successfully read. Previously, we asked for 1 item of the size of the file, to read the entire file. The error check which was added in r4915 assumed that the returned value of fread was the number of bytes read, which is not correct since only one item is returned, and causes Cactus to fail with a fatal error when any parameter file is loaded. The present commit changes the fread call to ask for file_size items of size 1, for which the error-checking code makes sense, as there are now file_size items returned. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4917 17b73243-c579-4c4c-a9d2-2d5706c11dac

* have CCTK_RegexMatch return a distinct error code if patterns is invalidrhaas2012-06-05
| | | | | | | | | | | | | | This patch changes the return value in the "does not compile" case to -1 and updates all source files that I could find that use it. Note that this patch changes behaviour of a routine. It used to return 0 for non-compiling patterns so thorns that test for C-like true would interpret invalid patterns as does-not-match, but will interpret the -1 return value as does-match. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4831 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Allow arithmetic expression in ParameterSetrhaas2012-04-11
| | | | | | | | | | | | | | | | | | Expression are of the form: foo::bar = 2*sin(foo:baz) ie. arithmetic and access to already set parameters. The new behaviour is triggered if the parameter string (for real, boolean and int parameters) does not parser properly as a double/int/bool. This last test is mostly an optimization. The largest change is actually in the expression parser which has been extended to handle eg. exponential notation and negations. It now uses a state machine to parse its input. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4797 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Make table printing functions publicly accessibleeschnett2011-11-09
| | | | | | | | | | | | The table data types (util_Table.h) have internal routines that print the table contents to screen. This can be helpful for debugging. This patch makes these functions publicly available. Add a routine Util_TablePrintPretty that converts a table to a nice, human-readable string. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4769 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Accept comments in multi-line strings in parameter fileseschnett2011-07-02

This makes it much easier to comment out variables in output strings. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4710 17b73243-c579-4c4c-a9d2-2d5706c11dac
* from Ian Hinder:knarf2011-01-06
| | | | | | | | | | | | | | | Correctly load parameter files with DOS line-endings Before this commit, when a parameter file with DOS line-endings was used, certain features of Cactus did not work correctly. For example, setting an output directory of $parfile would create an output directory named "$parfile" instead of expanding the parameter filename. This commit converts any CR-LF sequences to LF immediately after the parameter file is loaded. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4663 17b73243-c579-4c4c-a9d2-2d5706c11dac
* The function can get confused with detecting the end of the bufferschnetter2010-01-18
| | | | | | | | | | | | | | when the last line is in a comment or in a string, and may overrun the end of the buffer. The symptoms are error messages past the last line of the parameter file, because the memory after the buffer end is interpreted as (probably mal-formed) parameter file content. Since the paring routine is quite complex, this patch works around this problem by increasing the size of the buffer by a few characters and setting these to NUL. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4594 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Modify the behaviour of mixed C/Fortran string comparisons, so that itschnetter2009-12-05
| | | | | | | | | | | | | is consistent with the routines converting Fortran strings to C strings. Fortran strings have a fixed length, and trailing white space is usually ignored. The Cactus routine converting Fortran to C strings did already ignore trailing white space, but the routine comparing Fortran and C strings did not. This is now consistent. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4590 17b73243-c579-4c4c-a9d2-2d5706c11dac

The main changes are: - when reading a parameter file do not parse the file while reading, but read it first into a buffer, preprocess that and parse the buffer after that - replace the code which changes $parfile into the parameter file name to use this buffer preprocessing - replace $ENV{'*'} "defines" by environment variable values (*), e.g. $ENV{'HOME'} with $HOME.

* Cactus has currently an error in its parameter checking. Itschnetter2008-06-17
| | | | | | | | | | | | | | | | | | | | | | | | interprets ranges consisting of single numbers as allowing this number and all larger numbers. For example, the specification INT spatial_order "Order of spatial differencing" { 2 :: "second order" 4 :: "fourth order" } 2 allows all numbers not less than 2. This patch corrects this problem. Since this involves regular expressions which are often difficult to read, I have broken up the regular expressions into macros containing sub-expressions. I have also replaced calls to atoi and atof with calls to strtol and strtod, since these allow error checking which also was not present before. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4496 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Fixing Network.c for Cray XT4 Compute Node Linux Compatibility.jshalf2007-10-26
| | | | | | | | | | | | | | | | | | | | | | Network.c uses gethostbyname() which is available on the front-end nodes of the XT4, but not available on Compute Node Linux back-end nodes. The code will link fine with gethostbyname(), but will resolve to the dynamically shared library version of glibc. Since the Compute nodes do not understand dynamically linked libraries (only static linking), then it causes a fatal runtime error if gethostbyname() is invoked even though the compiler will not provide any warning that something bad will occur. Therefore, if you #define CRAY_XT, it will disable the gethostbyname() so as to prevent a fatal runtime error when GetHostName is called. Need to find out a way to recognize Cray XT4/Compute-node-Linux systems automatically. The front-end of the XT4 looks exactly like a Linux cluster. (uname returns "Linux"). Perhaps add a test to the Linux cluster known architectures file that points it to a XT4_CNL known-architetures file. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4434 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Correct logic errors in CCTK_TimerPrintDataI:schnetter2006-12-19
| | | | | | | | | | | | | | Timer handles are not numbered consecutively from 0 upwards. It is therefore not possible to test for legal timer number by checking the range [0, CCTK_NumTimers()). Instead, for each timer handle one has to check whether handled data exist. Remove the feature that a timer number of -1 prints all existing timers, since it is not possible (?) to iterate over all existing timers. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4396 17b73243-c579-4c4c-a9d2-2d5706c11dac
