CGI::Session Change Log
=====================================================================
4.20 - Monday, December 4, 2006
* INTERNAL: No Changes since 4.20_1. Declaring stable.
4.20_1 - Friday, November 24, 2006
* FIX: -ip_match now works even when it's not the last import item. (RT#21779)
* FIX: In the PostgreSQL driver, a race condition is when storing is now worked around. (Mark Stosberg)
* FIX: Added important clarification and example to MySQL driver docs that the session column
needs to be defined as a primary key to avoid duplicate sessions. (Justin Simoni, Mark Stosberg)
* FIX: The default serializer now works correctly with certain data structures. (RT#?) (Matt LeBlanc)
* FIX: A documentation bug in find() was fixed (Matt LeBlanc)
* FIX: Documented how to declare a database handle to be used on demand, which was introduced
in 4.04. (Mark Stosberg)
* FIX: Connections made with SQLite now disconnect only when appropriate, instead of always.
This addresses a symptom seen as "attempt to prepare on inactive database handle"
(Jaldhar Vyas, Sherzod, Mark Stosberg)
* FIX: Args to the constructor for CGI::Session and the drivers are now always shallow
copied rather than used directly, to prevent modification.
(RT#21952, Franck Porcher, Sherzod, Mark Stosberg)
* FIX: The documentation for expire($param, $time) was made more explicit
(pjf, Mark Stosberg)
* NEW: Added recommended use of flush() to the Synopsis (Michael Renner, RT#22333)
* NEW: Added links to Japanese translations of the documentation (Makio Tsukamoto)
http://digit.que.ne.jp/work/index.cgi?Perldoc/ja
* INTERNAL: Update test to workaround YAML versions less than 0.58. (Matt LeBlanc)
* INTERNAL: param() code was refactored for clarity (Mark Stosberg, Ali ISIK, RT#21782)
* INTERNAL: new() and load() were refactored (Ali Isik)
* INTERNAL: renamed some environment variables used for testing (Ron Savage)
* INTERNAL: Multi key-value syntax of param() now always returns number of keys
successfully processed, 0 if no key/values were processed.
4.14 - Sunday, June 11, 2006
* NEW: The find() command now has better documentation. (Ron Savage, Matt LeBlanc)
* FIX: find() no longer changes the access or modified times (RT#18442) (Matt LeBlanc)
* FIX: param() called with two parameters now returns the value set, if any (RT#18912) (Matt LeBlanc)
* FIX: driver, serializer, and id generator names are now untainted (RT#18873) (Matt LeBlanc)
* INTERNAL: automatic flushing has been documented to be unreliable, although
it was recommended in the past. Automatic flushing can be affected adversely
in persistent environments and in some cases by third party software. There are
also some cases in which flushing happened automatically in 3.x, but quit working
with 4.x. See these tickets for details.

4.13 - Wednesday, April 12, 2006
* FIX: Applied patch to fix cookie method (RT#18493,Nobuaki ITO)
* FIX: Berkeley DB 1.x exhibits a bug when used in conjunction with O_NOFOLLOW. Because of this,
we've removed it from the db_file driver. It will still attempt to stop symlinks but the
open itself has dropped the flag. (Matt LeBlanc)
* FIX: json and yaml db_file tests now check for the presence of DB_File. (Matt LeBlanc)
4.12 - Friday, April 7, 2006
* SECURITY: Fix possible SQL injection attack. (RT#18578, DMUEY)
4.11 - Friday, March 31, 2006
* FIX: Since 4.10, using name() as a class method was broken. This has
been fixed, and regression tests for both uses have been added. (Matt LeBlanc)
4.10 - Tuesday, March 28, 2006
* SECURITY: Hopefully this settles all of the problems with symlinks. Both the file
and db_file drivers now use O_NOFOLLOW with open when the file should exist and
O_EXCL|O_CREAT when creating the file. Tests added for symlinks. (Matt LeBlanc)
* SECURITY: sqlite driver no longer attempts to use /tmp/sessions.sqlt when no
Handle or DataSource is specified. This was a mistake from a security standpoint
as anyone on the machine would then be able to create and therefore insert data
into your sessions. (Matt LeBlanc)
* NEW: name is now an instance method (RT#17979) (Matt LeBlanc)
4.09 - Friday, March 16th, 2006
* SECURITY: Applying security patch from: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=356555 (Julien Danjou)
4.08 - Thursday, March 15th, 2006
* FIX: DESTROY was sometimes wiping out exception handling. RT#18183, Matt LeBlanc.
* SECURITY: Resolve some issues in: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=356555
- db_file and file now check for symlinks either explicitly or by using O_EXCL on sysopen
- file creation umask defaults to 660
* NEW: db_file and file drivers now accepts a UMask option. (Matt LeBlanc)
* INTERNAL: test suite clean up (Tyler MacDonald)
4.07 - Thursday, March 9th, 2006
* INTERNAL: MANIFEST update to fix release.
4.06 - Wednesday, March 3rd, 2006
* INTERNAL: MANIFEST update to fix release.
4.06 - Wednesday, March 8th, 2006
* FIX: some stray warnings when flushing: "Use of uninitialized value in numeric eq (==)" (RT#14603)
* NEW: JSON and YAML serializers (Tyler MacDonald)
* INTERNAL: CGI::Session::Test::Default accepts a "skip" argument,
listing tests that should be skipped. (Tyler)
4.05 - Friday, March 3rd, 2006
* FIX: Race condition fixed when writing to session files (RT#17949)
4.04 - Wednesday, March 01, 2006
* NEW: File driver now has option to disable flock (for those running
Win 9x, VMS, MacPerl, VOS and RISC OS). (Matt LeBlanc)
* FIX: If DBI driver was initialized using 'Handle', Driver::DBI::init()
returned false, and Driver::new() thought init faild and kept returning
undef. The problem was fixed by making sure Driver::DBI::init() returned
true. (Sherzod)
* Added .*cgisess.* to disclude cgisess.db, cgisess.id, and any session
files created in the t directory. (Matt LeBlanc)
* FIX: File driver now respects $CGI::Session::File::FileName for 3.9x
compatibility. (Matt LeBlanc)
* FIX: Default serializer now properly handles data structures that appear
more than once in the serialized data structure (before it'd result in data
structures that were equivalent but did not have the same address). (Matt LeBlanc)
* FIX: File driver now localizes the filehandle to avoid any possibility
of extended locking in persistent environments (Matt LeBlanc)
* FIX: File driver now locks the file when retrieving the session data (Matt LeBlanc)
* NEW: DBI Drivers now support a lazy loaded database handle. This is useful with the
CGI::Application plugin system. If the session is never used, the database handle may not
not need to be created. The syntax is to use a code ref:
Handle => sub {DBI->connect} (Mark Stosberg)
Finally, be aware that since 4.0 some people have reported problems with
the auto-flushing code. There may be an unresolved. You always call
flush() to be safe. Input or code contributions for the issue are
appreciated. Some related tickets include:

4.03 - Wednesday, October 05, 2005

* FIX: Default serializer can now serialize objects (Matt LeBlanc)

4.01 - Thursday, September 01, 2005

4.00 - Wednesday, August 31, 2005
*** NOTE ***
The 4.0 release represents a major overhaul of the CGI::Session code base.
Care has been taken to be 100% compatible with applications developed with 3.x.
However, you are encouraged to run regression tests with your own applications
before using this in production.

database-driven tests. (Mark Stosberg)

4.00_09 - Thursday, July 21, 2005
