2020-11-19treewide: rebrand to ucodeJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-11-16lib: optimize length() for objectsJo-Philipp Wich
Instead of counting the keys individually, use the existing json_object_object_length() function. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-11-16lib: extend length() to handle objectsJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-11-16lib: extend ord() to allow reading byte values at arbitrary indexesJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-11-16lib: add system() functionJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-31lib: fix potential null pointer deref on not found cmdline moduleJo-Philipp Wich
When a module is requested via -m but not found on the system, we do not have a context opcode available when instantiating the exception, which leads to a segmentation faul when attempting to access the source text offset. Avoid the deref by checking the opcode pointer for non-null. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-19lib: fix memory leaks in printf() and sprintf()Jo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2020-10-19lib: forward exceptions in callback functionsJo-Philipp Wich
- Ensure that exceptions ocurring in sort(), filter(), replace() etc. callback functions are properly forwarded to the caller - Also fix invalid free() invocations in ut_replace() Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-18lib: properly handle parse errors at EOFJo-Philipp Wich
At EOF, ut_parse_error() will receive 0 as token offset, which led to a null pointer dereference when creating the exception value. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-14treewide: unify error handlingJo-Philipp Wich
Get rid of the distinction between lexer/parser errors and runtime exceptions, use exceptions everywhere instead. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-14treewide: rework source file and callstack handlingJo-Philipp Wich
- Keep an open FILE* reference to processed source files in order to be able to rewind and extract error context later - Build a proper call stack when invoking utpl functions - Report call stack in exceptions Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-14lexer: rewriteJo-Philipp Wich
Rewrite the lexer into a restartable state machine to support parsing from file streams without the need to read the entire source text into memory first. As a side effect, the length of labels and strings is unlimited now. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2020-10-02lib: wrap runtime exceptions in included utpl codeJo-Philipp Wich
This is needed to preserve error context information. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-02lib: tweak error context formattingJo-Philipp Wich
Do not emit additional newline when formatting error context and print it instead when outputting the exception. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-02treewide: rework handling of memory allocation failuresJo-Philipp Wich
Instead of propagating failures to the caller, print a generic error message and terminate program execution through abort(). Signed-off-by: Jo-Philipp Wich <jo@mein.io>

This reverts commit 54bb15b2be3656e91386b80074f45591b20fed3f. Relying on setjmp() / longjmp() causes too many headaches trying to track and properly release intermediate values. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
