At the moment we support only these types:
SQLT_NUM, SQLT_INT, SQLT_LNG - integer/long
SQLT_FLT - float
SQLT_AFC, SQLT_CHR, SQLT_VCS, SQLT_AVC, SQLT_STR, SQLT_LVC - char/varchar
SQLT_ODT - date
More supported types may follow.
This updated fixes (this list is not complete):
-------------------
#33915 - crash in _oci_close_session
#26393 - Segfault during request shutdown in _oci_close_session() (oci8.c:2443)
#32741 - hang on ociexecute() with collections (only with 10g, works with 9i)
#32325 - can't retrieve collection using OCI8
#33583 - Apache1.3.33 Segmentation fault with php5 & OCI_New_Collection
#32361 - connection oci_connect stay persist after process the php
#29013 - multiple logins cause handles become invalid
#28944 - OCITypeByName: OCI-21522 with two connections
Fixed by connection handling rewrite.
#32140 - NVARCHAR columns are truncated
#31042 - oci_fetch_* sets field value to false
#27156 - OCIFetchInto returns false as column value when column contains >1 umlaut
Fixed by multiplying buffer size by 3.
#33866 - OCIlogon do not returns conn resource for account with expired paswd
#33365 - logon fails when password expires
Fixed by adding new oci_password_change() call syntax.
#33159 - DB-connect via webserver fails after DB-restart ORA-24327
#30808 - oci8 cannot connect after restarting DB
#30127 - lost oracle connection. need restart apache.
#29902 - oci8 doesn't disconnect sessions, overloads oracle server
#29779 - (the same issue with the Oracle server going offline)
#26829 - Killed Oracle Sessions openned with OCIPLogon()
Fixed by adding oci8.ping_interval option.
#32988ext/oci8: OCI doesn't support DB external authentication
Fixed by adding support of external credentials (turned off by default).
Added new INI options:
----------------------
oci8.ping_interval
oci8.max_persistent
oci8.persistent_timeout
oci8.privileged_connect
oci8.statement_cache_size
oci8.default_prefetch
oci8.old_oci_close_semantics
See the updated docs for the detailed descriptions.
Major changes:
--------------
- connection handling algorithm rewritten. That should add stability and fix all non-reproducible crashes etc;
- extension refactored and divided into several files to improve readability and to make it easier to maintain;
- added support of statement caching;
- added support of privileged connections using external credentials;
- added new INI options to manage persistent connections;
- fixed oci_close() to close connections correctly.
- we decide to either not support ZTS connection pooling (kind of
- pointless as PHP isn't stable in ZTS mode) or fix the 100% reproducable
- crash bug on oci_connect() under Windows most probably due to this
- problem.
used to return "" and not bool(false). It's not worth keeping it because
STR_FREE() and zval_dtor() always have to check for it and it slows down
the general case. In addition, it seems that empty_string has been abused
quite a lot, and was used not only for setting zval's but generally in
PHP code instead of "", which wasn't the intention. Last but not least,
nuking empty_string should improve stability as I doubt every place
correctly checked if they are not mistakenly erealloc()'ing it or
calling efree() on it.
NOTE: Some code is probably broken. Each extension maintainer should
check and see that my changes are OK. Also, I haven't had time to touch
PECL yet. Will try and do it tomorrow.
*add constant's alias, coz others do have aliases
*change protos (oops =))
*add notices to collection functions
*change coll_element_get & coll_assign to inform user, that this type of element is not supported yet.
change almost all func names to match naming conventions
keep ocifetchinto & *buffering for awhile - they will be rewritten soon
old names are kept as aliases
rename constant and add library check to config.m4
add info lines to see if Collection & Temp Lob support enabled or not
add OCI_THREADED to use thread safe OCI mode with ZTS (should fix bug #26558)
@- added ZTS connection pooling support to the oci extension
@ connections will now be pooled per process and not
@ per thread anymore. the number of persistent and active
@ connections is now also shown in the phpinfo() output (harald)
ocitelllob(); [ OCI_Lob->tell(); ] - ftell(); analogue for Lobs
ociwritelob(); [ OCI_Lob->write(); ] - fwrite(); analogue for Lobs
ocitruncatelob(); [ OCI_Lob->truncate(); ] - ftruncate(); analogue for Lobs
ocieraselob(); [ OCI_Lob->erase(); ] - erases specified part of a Lob (for BLOBs it means zero-filling, for CLOBs - space-filling)
ociflushlob(); [ OCI_Lob->flush(); ] - flushes Lob buffer (if buffering was enabled before)
ocisetbufferinglob(); [ OCI_Lob->setBuffering(); ] - turns on/off buffering for the current Lob
ocigetbufferinglob(); [ OCI_Lob->getBuffering(); ] - gets buffering' current state
ocirewindlob(); [ OCI_Lob->rewind(); ] - rewind(); analogue for Lobs
ocireadlob(); [ OCI_Lob->read(); ] - fread(); analogue for Lobs
ocieoflob(); [ OCI_Lob->eof(); ] - feof(); analogue for Lobs
ociseeklob(); [ OCI_Lob->seek(); ] - fseek(); analogue for Lobs
ocilobgetlength(); [ OCI_Lob->getLength(); ] - filesize(); analogue for Lobs
ociappendlob(); - appends data from a Lob to another Lob
ocicopylob(); - copies data from a Lob to another Lob
ociisequallob(); - compares 2 Lobs and checks if they are equal
TODO cleanup
and other minor fixes
Nuke a sprintf (slooow)
And embed the charset as part of the hashed details (persistent conn key),
because the function otherwise happily returns incompatible connections.
(e.g. US7ASCII vs. UTF8; the client-side charset is not alterable once a
connection has been established.)
