This fixes bug #14522. I've tested that it does not cause a segfault under
RH 7.2, and retains all functionality. I recommend that this patch be
considered for the PHP_4_2_0 tree as well, as having a function that core
dumps every time is a bad thing(TM).
- changed 'double' to 'float'
- changed 'int' to 'resource' where appropriate
- format change: proto has to be on a single line and description
on the very next one, some tools still rely on this
-everything uses new data structures
-new function exif_thumbnail
#nearly stripped off all jhead code
@read_exif_data is now an alias for exif_read_data
@ important to differenciate old/new version for tests)
@new function exif_tagname returns the names of tags
@new function exif_thumbnail extracts embedded thumbnail (Marcus)
#switched to internal version 1.2
I don't have time right now to leave in the good ones and remove
only the bad ones.
There are some semantical changes which I reject, because
they aim at fixing a bug which is at a completely other location.
Then SID does not gefined anymore properly. (This broken patch
has not been sent to me at all.)
Also, there were *so* many whitespace changes which already
make these commits bogus.
Redesigned socket_recv() as outlined on php-dev
Modified socket_last_error() to no longer clear the error
Added socket_clear_error()
Fixed socket_set_nonblock()
Added socket_set_block()
Fixed a proto
Saved 1 byte of RAM : )
posix_strerror() (convert error number into error string).
- Do not output any error message if any of the function fails with FALSE
return value. The proper way now is to call posix_errno() and
posix_strerror() after encountering an error condition.
- Function not support on a system no longer issue a 'not available' error
but simply don't exist so we can safely use 'function_exists'.
- Fixed protos.
- Use new parameter parsing API.
- posix_uname() may be aware of 'domainname' (GNU extension)
- posix_getgrnam(), posix_getgrgid(): the returned information does no
longer contains mixture of string and numbered keys (hash / array)
but contains key 'member' with an array of all members in a list
(or an empty array). This breaks BC but is the right thing IMHO.
information, a few spaces won't hurt (and multiple ones are rendered
as one by browsers anyway). Micro-benchmarks which use phpinfo()
as a mean to generate output will yield more through-put now
(35 req/s vs. 83 req/s in tux).
-Changed parameters after checking bugdatabase and discussion with
Rasmus: 1st=Filename, 2nd=NeededSections
# 3rd=Thumbnail, 4th=All
# 3rd and 4th parameter are currently diabled because the code
# does not work correctly (will correct this in later versions).
# Changing the parameters will not cause any problems because the
# old parameter functions never found their way in documentation
# and the they did not work...
@-Added TIFF support
@-Changed parameters after checking bugdatabase and discussion with Rasmus
@ 1st=Filename, 2nd=NeededSections
@ If the 2nd parameter is not present or 0 or '' the function will return
@ a result array even if no data was read from file.
# Personally i consider a default behaviour to generate no array if
# no data is present as a bad idea because here we can generate as
# much information as possible....
@ If the 2nd parameter is a string then that string describes which
@ sections have to be present in the file to generate a result array.
@ If none of the needed section is found the result will be false.
@ Section strings are "ANY_TAG","IFD0","COMMENT","EXIF","GPS","INTEROP"
@ "FPIX","APP12". Each string has to be separated by a colon. So
@ "COMMENT,EXIF" returns an array if either a comment or an Exif
@ section is present. "IFD0" is standard datastructure in a TIFF/JPEG
@ file that contains image information. "EXIF" is the Exif structure
@ of TIFF/JPEG (IFD0 subdirectory). "GPS", "INTEROP", "FPIX", "APP12"
@ are additional IFD0 subdirectories. The APP12 support is an
@ experimental Olympus support.
# Do not worry this is no problem, it is safe.
@(Marcus)
Abstracted string -> ipv4 value conversion which unifies all functions
Standardized Host Lookups
Fixed Broken host error values
Fixed error detection in sendmsg
Added some safety struct zeroing
Modified bind to consitentlyy use sockaddr_storage(not just for AF_UNIX)
#Note this could potentially break the build on other platforms, as I have
#not tested them yet (Will soon though)
are supplied, but you do not want to provide a row number yourself.
@- Make the 2nd parameter to pgsql_fetch_* support NULL in case 3
@ parameters are supplied, but you do not want to provide a row number
@ yourself. (Derick)
+New function exif_headername can be used to read the internal Tag namelist (was mainly created for debugging purpose but maybe somone writes code to create/update exif headers here).
+An internal version number is present.
+A testpage is supplied test.txt describes how the test works.
+The oldfunction read_exif_data has got an alias exif_read_data
As the old version of this module is very buggy i decided to implement the testpage (test.txt) and to create the alias. The test script only works with the alias as the old version does not pass tests. By the way it seems a good way to prepend 'exif_' to all functions in the module.
(DO NOT document this function yet)
Fixed crash bug with ob_end_*() function. ob_end_*() will not delete
buffers that may not be deleted.
php_start_ob_buffer() and php_ob_set_internal_handler() takes parameter for
if the buffer created may be deleted or not.
Added 3rd parameter "bool erase" to ob_start(). If FALSE, buffer may not be
deleted until script finshes.
Changed ob_*() function that have void return type to bool. All ob_*()
functions return TRUE for success, FALSE for failure.
@ - Added ob_get_status() to get array of buffers and it's status. (Yasuo)
@ - Fixed crash bug with ob_end_*() function. ob_end_*() will not delete
@ buffers that may not be deleted. (Yasuo)
@ - Added 3rd parameter "bool erase" to ob_start(). If FALSE, buffer may not be
@ deleted until script finshes. (Yasuo)
@ - Changed ob_*() function that have void return type to bool. All ob_*()
@ functions return TRUE for success, FALSE for failure. (Yasuo)
+Added Description,Artist
+Added missing memory deallocation
+Corrected error with multiple comments
+Corrected handling of ExifVersion, Tag has 4 ASCII characters *WITHOUT* NUL
+Corrected handling of Thumbnailsize if current source detects size < 0
+Changed all fields to char* that do not have a maximum length in EXIF standard
+Undocumented second Parameter ReadAll frees memory to early -> moved to third position default changed to false -> faster
+New second Parameter [true|false] to specify whether or not to to read thumbnails -> reading is timeconsumpting suppose default should be false -> done so
