From Revision 356 to 129

Rev	Summary	Authors	Tags	Date
330	Merge mutable-variables-flush-leak [r=jkakar,jukart] Merge mutable-variables-flush-leak [r=jkakar,jukart] Remove a leak when mutable variables (ListVariable or PickleVariable instances) are collected before store.flush, leaving hooks behind them.	Thomas Hervé		15 years ago
301	Fix ListVariable.get(to_db=True) to convert its elements cor... Fix ListVariable.get(to_db=True) to convert its elements correctly. This caused problems for element types that had significantly different Python and database representations such as EnumVariable. [r=therve,jkakar] [f=136806]	James Henstridge		16 years ago
298	Merge bug-334084 [r=niemeyer,jkakar] [f=334084] Merge bug-334084 [r=niemeyer,jkakar] [f=334084] Remove an unnecessary update on object containing a List variable when the object is in the cache, by checking if the checkpoint state is defined.	Thomas Hervé		16 years ago
296	Add a UUID property type to Storm. Add a UUID property type to Storm. [r=jkakar,niemeyer] [f=310404]	James Henstridge		16 years ago
275	Merge variable-referenceset-leak [r=niemeyer,jkakar] Merge variable-referenceset-leak [r=niemeyer,jkakar] Change the way MutableValueVariable hooks up to the store event system, by overriding get and set. This works around a leak discovered when using PickleVariable in a ReferenceSet.	Thomas Hervé		16 years ago
272	Merge variable-leak [r=jkakar,niemeyer] Merge variable-leak [r=jkakar,niemeyer] Fix a leak of Variable instances recently introduced by the flush event of the store. It affected every object defining a Pickle or List property.	Thomas Hervé		16 years ago
271	Merge 277095-update-cache [f=277095] [r=jamesh,niemeyer] Merge 277095-update-cache [f=277095] [r=jamesh,niemeyer] Fix a bug where updating a field to its previous value was not detected by the store, thus not updating the value in the database.	Thomas Hervé		16 years ago
270	Merge 276690-variable-hash [f=276690] [r=jamesh,niemeyer] Merge 276690-variable-hash [f=276690] [r=jamesh,niemeyer] Change the way objects are stored in the cache, using variables values instead hashing variables directly, removing the need of equality and hash methods on Variable class. This fixes a bug when using ListVariable and PickleVariable because they couldn't be hashed correcly and so used in the event system.	Thomas Hervé		16 years ago
269	Merge no-alive-flush [r=niemeyer,jkakar] Merge no-alive-flush [r=niemeyer,jkakar] Remove the need to iterate all objects in the alive set at flush time by using a flush event subscribed by variables holding mutable values (pickle and list). This improves performance drastically when lots of objects are in the cache.	Thomas Hervé		16 years ago
247	Add __slots__ definitions to Variable and Expr classes and s... Add __slots__ definitions to Variable and Expr classes and subclasses. This reduces the memory usage of the most common Storm objects by removing their class dictionaries. [r=niemeyer,radix]	James Henstridge		16 years ago
245	Merging need-for-speed-revenge branch [a=niemeyer,jamesh,rad... Merging need-for-speed-revenge branch [a=niemeyer,jamesh,radix] [r=jamesh,therve] This branch introduces a number of fixes, optimizations, and extensions on the cextensions module, with speedup purposes. The module is now built by default, but still disabled unless the STORM_CEXTENSIONS=1 environment variable is defined. Besides these, Chris also provided a mechanism to cache ClassAliases, to prevent the cost of rebuilding the ClassInfo for each alias.	Gustavo Niemeyer		16 years ago
223	Merged validator branch [r=jamesh,radix] [f=218381] Merged validator branch [r=jamesh,radix] [f=218381] All properties now accept a "validator" parameter. When used, a function like validate(object, attribute_name, value) should be given, and it may validate or modify the value before it's set in the property. The value assigned to the property is the result of the validator, so the original value should be returned if changing it isn't intended.	Gustavo Niemeyer		16 years ago
205	Merged timedelta-improvements branch [r=radix,jkakar] [f=163... Merged timedelta-improvements branch [r=radix,jkakar] [f=163565] Improved support for TimeDelta properties on all backends. Many more formats are accepted now, and some issues were fixed.	Gustavo Niemeyer		17 years ago
167	Merge no-underscore-parse-methods [r=niemeyer,jkakar] [f=128... Merge no-underscore-parse-methods [r=niemeyer,jkakar] [f=128060] Now it's easy to tell what you can touch in Storm: If it begins with an underscore, you definitely can't touch it in any way. If it doesn't begin with an underscore, read the documentation to see how it's meant to be used. If it doesn't have a docstring, file a bug. :-) This branch renames _parse_get, _parse_set, _from_database, _to_database, _build_raw_cursor, _raw_execute, _result_factory, _param_mark, _compile, and _connection_factory so that they no longer have preceding underscores, because they were all meant to be overridden in subclasses. Documentation was added on their intended usage. It also adds a LOT of documentation to store.py, variables.py, and database.py, and fixes a few existing docstrings to be valid epytext.	Christopher Armstron...		17 years ago
162	Merged need-for-speed branch [r=jkakar,radix] [f=126875] Merged need-for-speed branch [r=jkakar,radix] [f=126875] This branch introduces a new cextensions C module which offers faster versions of a few core types in Storm. It's not yet built by default, as more testing is needed before considering it as a good alternative. A bug was also fixed: ResultSet.cached() wasn't behaving properly when working with dead objects.	Gustavo Niemeyer		17 years ago
157	Merged storm-numeric branch, by Johan Dahlin [r=jamesh,nieme... Merged storm-numeric branch, by Johan Dahlin [r=jamesh,niemeyer] This branch introduces support for Decimal properties in Storm.	Gustavo Niemeyer		17 years ago
150	Merged the reserved-words branch [r=jkakar,radix] [f=126875] Merged the reserved-words branch [r=jkakar,radix] [f=126875] This branch introduces the capability of properly escaping words defined as reserved by SQL1992. Backends are also free to introduce their own reserved words if wanted. Compatibility notes: - compiler handlers had their arguments reordered, to support a unification that cleaned up the way that handlers are used. - compile now returns only the statement. To get parameters, one must pass the State explicitly. - compile.fork() is now compile.create_child() to better reflect the relationship between parent and child. - The __object_info and __class_info attributes are now __storm_object_info__ and __storm_class_info__.	Gustavo Niemeyer		17 years ago
147	- The Chars type is now RawStr. Chars will stay as an alias... - The Chars type is now RawStr. Chars will stay as an alias for one or more releases. [r=jkakar,michelp,radix] - Added ClassAlias to the locals module. - Some TODO tweaking.	Gustavo Niemeyer		17 years ago
140	Binary is now Chars! Binary is now Chars!	Gustavo Niemeyer	0.9	17 years ago
129	Added LGPL version 2.1 in the LICENSE file, and a standard Added LGPL version 2.1 in the LICENSE file, and a standard copyright/license header on all files.	Gustavo Niemeyer		17 years ago
