phar_get_pharfp() can return NULL. In this case this is because the
stream gets closed by the include code in the engine. However, the phar
entry is still cached, so when the next include happens the engine tries
to read from a closed (and nullified) stream.
Use the same fix as in phar_open_entry_fp(): take into account that the
phar_get_pharfp() can return NULL and in that case reopen the phar
archive.
Closes GH-13056.
On ZTS, the global variables are stored in dynamically allocated memory.
When the module gets shut down this memory is released. After the module
is shut down, only then are the persistent resources cleared. Normally
this isn't an issue, but pgsql and odbc refer to the globals to modify
some counters, after the globals have been freed.
Fix this by guarding the modification.
Closes GH-13032.
There's two issues here:
- freeing of predefined entity declaration crashes (unique to 8.3 & master)
- using multiple entity references for a single entity declaration crashes
(since forever)
The fix for the last issue is fairly easy to do on 8.3, but may require a
slightly different approach on 8.2. Therefore, for now this is 8.3-only.
Closes GH-13004.
I forgot to also update the document reference of attributes, so when
there is no document reference anymore from a variable, but still an
attribute, this can crash. Fix it by also updating the document
references for attributes.
Closes GH-13002.
Thanks to Maurício Fauth for finding and reporting this bug.
The bug was introduced in October 2022. It originally only affected
text encodings which do not have a fixed byte width per characters
and for which mbstring does not have an mblen_table. However, I recently
made another change to mbstring, such that mb_substr no longer relies
on the mblen_table even if one is available. Because of this change,
the bug earlier introduced in October 2022 now affected a greater
number of text encodings, including UTF-8.
Because these functions are copied and not properly registered (which we
can't), the observer code doesn't add the temporaries on startup.
Add them via a callback during startup.
Closes GH-12906.
Move SimpleXML invalidation code after node checks
This is safe, i.e. the tree hasn't been modified yet, because either we
didn't call a libxml modification function yet, or xmlNewChild is called
with a NULL pointer, which makes it bail out and return NULL.
Closes GH-12947.
