PCRE only validates the string starting from the start offset
(minus maximum look-behind, but let's ignore that), so we can
only remember that the string is fully valid UTF-8 is the original
start offset is zero.
We need not just the whole string to be UTF-8, but the start
position to be on a character boundary as well. Check this by
looking for a continuation byte.
This helps to avoid unnecessary IS_REFERENCE checks.
This changes some notices "Only variables should be passed by reference" to exception "Cannot pass parameter %d by reference".
Also, for consistency, compile-time fatal error "Only variables can be passed by reference" was converted to exception "Cannot pass parameter %d by reference"
As seen in the gdImageRotateBicubicFixed() function the same setup
occurs but it uses signed integers, therefore we use also use
signed integers in gdImageRotateBilinear()
Moreover, these two functions have been removed upstream in
https://github.com/libgd/libgd/commit/bd6d2e101f6f1df106d1cd2e2dc8058a5538109b
therefore we should also mimic upstream and remove them...
Thanks to @cmb69 for pointing it out.
To cater to `curl_copy_handle()` of cURL handles with attached
`CURLFile`s, we must not attach the opened stream, because the stream
may not be seekable, so that we could rewind, when the same stream is
going to be uploaded multiple times. Instead, we're opening the stream
lazily in the read callback.
Since `curl_multi_perfom()` processes easy handles asynchronously, we
have no control of the operation sequence. Since duplicated cURL
handles may be used with multi handles, we cannot use a single arg
structure, but actually have to rebuild the whole mime structure on
handle duplication and attach this to the new handle.
In order to better test this behavior, we extend the test responder to
print the size of the upload, and patch the existing tests accordingly.
Not all systems support the discard protocol (TCP port 9), and since
there is no particular reason to use it, we switch to using actual
server testing.
The culprit is the too restrictive fix for bug #71536, which prevents
`php_libxml_streams_IO_write()` from properly executing when unclean
shutdown is flagged. A *more* suitable solution is to move the
`xmlwriter_free_resource_ptr()` call from the `free_obj` handler to an
added `dtor_obj` handler, to avoid to write to a closed stream in case
of late object freeing. This makes the `EG(active)` guard superfluous.
We also fix bug79029.phpt which has to use different variables for the
three parts to actually check the original shutdown issue.
Thanks to bwoebi and daverandom for helping to investigate this issue.
Since we're dealing with floating point numbers, precision issues may
hit us, and actually it's not necessary to check for the exact number
anyway, because it is not exact in the first place. Therefore, we
relax the test expectations.
We have to convert to number *before* detecting the type, to cater to
internal objects implementing `cast_object`.
We also get rid of the fallback behavior of using `FORMAT_TYPE_INT32`,
because that can no longer happen; after `convert_scalar_to_number_ex`
the type is either `IS_LONG` or `IS_DOUBLE`. We cater explicitly to
the `IS_ARRAY` case what also avoids triggering a type confusion when
`::TYPE_INT64` is passed as `$type`.
