The non-libuv tcp server implementation had several issues:
* Relied on EINTR or self-connect through global vars for breaking,
which did not work during recv() for example.
* Never retried on EINTR
* Called recv() only once, thus subject to fragmentation issues
To support breaking otherwise blocking socket calls, RzStopPipe has been
imported from chiaki (I am the sole author so I can relicense).
rz_socket_block_time() was also detected to be doing the exact opposite
than it should on Windows through the tests, and fixed.
* Replace on s390x failing tms320 c55x test with c55x+ test.
* Fix resource leaks of parse paramters.
* Revive unreachable code.
* Raplace test with one which has not a different asm string in Capstone v3.
* Rename `new` to `newt` since `new` is a keyword and should not be used as var name.
This introduces the ability to split asm strings into tokens and assign a type to them.
This means:
* Each asm strings is assigned a list of tokens. Each token points to a sub-string.
* A token has a type attached which describes it (e.g. register token, operator token, mnemonic token etc.)
* A generic parsing method is introduced which splits an asm string into tokens. The pattern it parses is `<mnem> <op> <op> ...`.
* Instead of the generic method, plugins can create the token strings on their own.
* An API method was introduced to help plugins implement their own parsing methods via regex patterns.
* Custom token strings are stored in `RzAsmOp.asm_toks`
Additionally the coloring of asm strings is now exclusively done via the token strings.
* For this a function was added to colorize tokenized asm strings according to their token types.
* Fix some UTF8 not being considered characters
* Fix broken selection between `smatcher()` and `lmatcher()`
* Fix broken regex maching for `lmatcher()` (big state machines) engine
* Use `long long` for short state machine type
* Add tests
* Add utility functions to search for UTF-8 chars in strings.
* Break loop if number of read bytes goes beyond str.
* Add doxygen to `rz_mem_cmp`
* Add NULL checks to functions.
* Drop sdb_json in `librz/cons/grep.c`
* Do not print the JSON key in grep
* Use proper JSON paths in tests
* Use signed number in case of RzJson in tests
* Do not add quotes for sole RZ_JSON_STRING
Allowing converting the primitive json values null, number, string and
bool to be converted to strings is useful, simplifies the code and fixes
crashes when converting otherwise valid RzJson objects.
**Register profile parsing**
- Types, sizes, and offsets get now parsed separately in their own functions.
- More logging added.
- The string is first parsed into a list of register definitions and alias (`RzRegProfileDef`, `RzRegProfileAlias`) and afterward applied to `RzReg.regset`.
- Documentation was added on how the register profile needs to be formatted.
- Functions are more consistent with return types (most return `bool` now instead of `Error Msg` + `NULL`).
**New register profile structs**
The register profile of `RzReg` consists of two lists with alias and definitions.
I chose lists over NULL-terminated arrays because they were a little easier to handle during parsing (no memory management).
Please let me know if you would strongly prefer the NULL-terminated version.
* Kill the thread only if is alive.
* Remove rz_th_lock_guard.
* Use rz_sys_usleep since pthread_yield/sched_yield are not portable.
* Kill threads only on error.
* Avoid killing already-dead threads.
* RzThreadFunction now returns void* and added test_thread_queue.
* Removed pthread_exit
* Improved false-positive detection in str_search
This commit adds the following features:
- Extend the false-positive check on ASCII frequencies to all UTF strings
- Add a global option to activate/deactivate di check
- Improve the false-positive heuristic by adding a special case for extended-ASCII strings
Before this patch the function was using RZ_PREFIX even when IS_PORTABLE
was set, making the function not working well because RZ_PREFIX might
not exist in the system where the portable build is used (the path was
passed to realpath(), which requires an existing path).
This patch fixes the problem by searching for the BINDIR without using
realpath() on the RZ_PREFIX. Moreover, it avoid retrieving the same
prefix every time by saving it in a global variable.
* Add rz_constructor.h to allow defining constructors/destructors on
multiple compilers.
Range is now explicitly inclusive/inclusive to allow generating stats
for the entire 64bit range.
This especially also removes the obscure "Cannot alloc for this range",
which could be observed in Cutter, and adds a more meaningful error to
the p- command whenever no range is available.
All uses of rz_str_filter already passed either strlen(..) or -1 or 0,
which was the same as computing strlen(...). The only case where a
different value was passed was in astr.c, where the string was anyway
allocated with rz_str_ndup(). Thus the string passed to rz_str_filter()
is always zero-terminated and we don't need to compute the length in
rz_str_filter() to traverse it all, but we can just stop at the first
NULL byte.
Although the reg profile was not really used yet it will be relevant for the RZIL uplifting.
Introduces:
* Double/quadruple registers now properly overlap with their counterparts.
* Registers have correct types assigned (vec, ctr, sys etc. Before, all regs were of type gbr)
* Consistent register names (asm name style: c3:2, r31 etc, alias style: lc1:sa1, lr etc.)
* Adds _tmp registers in the profile. Later used by uplifted instructions (think of .new registers).
This has the same meaning as rz_analysis_get_address_bits(), i.e. the
size of an address, which is often, but not always the same as the
"asm.bits" bitness, especiall in thumb where it has to be 32, rather
than 16. This fixes pointer size calculation for such cases.
