Dead since almost 5 years with commit ae4ac9f ("properly free memory on
shutdown")
|
|
Can causes issues on uncommon architectures, like s390x.

No need to use an ulong, an uint is more than enough for our usecases.
This fixes the following warning:
```
src/sp_config.c:207:20: runtime error: store to misaligned address 0x796d1f9a78d4 for type 'u_long', which requires 8 byte alignment

SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior src/sp_config.c:207:20 in
```
|
|
Annotate the common logging function sp_log_msgf() with the format
attribute so compilers can check the used format string and passed
arguments for discrepancies.
Adjust the lineno printing by using %zu and the type size_t
consistently.

Bug introduced in https://github.com/jvoisin/snuffleupagus/commit/7c2d1d7d2713c0fa6bda63c376baf25d9f3d712c

* for easier memory manegement, the entire sp_config struct was merged into snuffleupagus_globals and allocated on stack where possible
* SNUFFLEUPAGUS_G() can be written as SPG(), which is faster to type and easier to read
* execution_depth is re-initialized to 0 for each request
* function calls with inline string and length parameters consistently use ZEND_STRL instead of sizeof()-1
* execution is actually hooked if recursion protection is enabled
* some line breaks were removed to make the code more readable

Add the possibility to log directly into the syslog, instead of using php's log system.
|
|
|
|
|

This should fix the following:
```C
snuffleupagus/src/sp_config.c:193:10: warning: implicit declaration of function 'getline' is invalid in C99 [-Wimplicit-function-declaration]
while (getline(&lineptr, &n, fd) > 0) {

Ensure that certificates are verified in curl
should close #47
|
|
This commit replace our usage of `php_log_err` with `zend_error`. This should
allow administrators to display errors in the webpage, should they want to;
and to properly manipulate the verbosity's level.
This should close #217

This commit does a lot of things:
- Use hashtables instead of lists to store the rules
- Rules that can be applied at launch time won't be tried at runtime
- Improve feedback when writing nonsensical rules
- Make intensive use of `zend_string` instead of `char*`

* Trying to fix sloppy comparison https://github.com/nbs-system/snuffleupagus/issues/10 by

Implement session encryption.
|
|
|
|
This should close #129

|
|
|
Implement whitelist in eval
|
|
Add support for eval filtering, only blacklist for now
|
|
Thanks to @fr33tux for the bug report ♥

- `clang-format --style="{BasedOnStyle: google, SortIncludes: false}" -i snuffleu*.c sp_*.c sp_*.h`
- Update the documentation accordingly
|

It's now possible to encrypt cookies matching a specific regexp.
This should close #106
|
|
Since we now have sp_list and sp_tree, it makes sense to specify that
nodes are only for lists.
|
|
Thanks to this huge commit from @xXx-caillou-xXx, we can now write amazingly flexible rules.
