[issue42958] filecmp.cmp(shallow=True) isn't actually shallow when only mtime differs
Christof Hanke added the comment: Hi Andrei, I would follow rsync. >From the man page: """ [...] -c, --checksum This changes the way rsync checks if the files have been changed and are in need of a transfer. Without this option, rsync uses a "quick check" that (by default) checks if each file’s size and time of last modification match between the sender and receiver. [...] """ so, yes you can have false positives with a shallow comparison of size + mtime only. But that's usually ok for e.g. incremental backups.

[issue41354] filecmp.cmp documentation does not match actual code
Christof Hanke added the comment: I understand that you are reluctant to change existing code. But for me as a sysadmin, the current behavior doesn't make sense for two reasons: * st.st_size is part of _sig. why would you do a deep compare if the two files have a different length ? * comparing thousands of files, a proper shallow-only compare is required, since it takes a long time to compare large files (especially when they are migrated to a tape-backend), so a silent-fallback to a deep-compare is not good. -- ___ Python tracker <https://bugs.python.org/issue41354> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue41354] filecmp.cmp documentation does not match actual code
New submission from Christof Hanke : help(filecmp.cmp) says: """ cmp(f1, f2, shallow=True) Compare two files. Arguments: f1 -- First file name f2 -- Second file name shallow -- Just check stat signature (do not read the files). defaults to True. Return value: True if the files are the same, False otherwise. This function uses a cache for past comparisons and the results, with cache entries invalidated if their stat information changes. The cache may be cleared by calling clear_cache(). """ However, looking at the code, the shallow-argument is taken only into account if the signatures are the same: """ s1 = _sig(os.stat(f1)) s2 = _sig(os.stat(f2)) if s1[0] != stat.S_IFREG or s2[0] != stat.S_IFREG: return False if shallow and s1 == s2: return True if s1[1] != s2[1]: return False outcome = _cache.get((f1, f2, s1, s2)) if outcome is None: outcome = _do_cmp(f1, f2) if len(_cache) > 100: # limit the maximum size of the cache clear_cache() _cache[f1, f2, s1, s2] = outcome return outcome """ Therefore, if I call cmp with shallow=True and the stat-signatures differ, cmp actually does a "deep" compare. This "deep" compare however does not check the stat-signatures. Thus I propose follwing patch: cmp always checks the "full" signature. return True if shallow and above test passed. It does not make sense to me that when doing a "deep" compare, that only the size is compared, but not the mtime. --- filecmp.py.orig 2020-07-16 12:00:57.0 +0200 +++ filecmp.py 2020-07-16 12:00:30.0 +0200 @@ -52,10 +52,10 @@ s2 = _sig(os.stat(f2)) if s1[0] != stat.S_IFREG or s2[0] != stat.S_IFREG: return False -if shallow and s1 == s2: -return True -if s1[1] != s2[1]: +if s1 != s2: return False +if shallow: +return True outcome = _cache.get((f1, f2, s1, s2)) if outcome is None: -- components: Library (Lib) messages: 374054 nosy: chanke priority: normal severity: normal status: open title: filecmp.cmp documentation does not match actual code type: behavior ___ Python tracker <https://bugs.python.org/issue41354> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue33638] condition lock not re-acquired

[issue33638] condition lock not re-acquired
New submission from christof <chbai...@gmail.com>:
Hello,
I have a simple code which triggers a timeout if a task did not complete
import asyncio
async def task_timeout():
condition = asyncio.Condition()
with await condition:
try:
await asyncio.wait_for(condition.wait(), timeout=4)
except asyncio.TimeoutError as e:
print("timeout reached")
# uncomment this line to make the code work
# await asyncio.sleep(0)
f = asyncio.ensure_future(task_timeout())
loop= asyncio.get_event_loop()
loop.run_until_complete(f)
It throws an exception when leaving the scope for the condition because it
expects the lock to be acquired:
RuntimeError: Lock is not acquired.
If you uncomment the line to sleep, it will work because it will continue in
the coroutine Condition.wait and call:
yield from self.acquire() => locks.py line 355
I think this is a bug and that this behaviour is not the expected one.

ANN: cssutils 0.9.8a2
what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) about this release -- 0.9.8a2 is a bugfix release. Compatibility to Python 3.x is currently in development. At the same time Python 2.4 and Python 2.5 compatibility will probably be lost... 0.9.8 will be the last version to support Python 2.4 and Python 2.5. main changes - BUGFIX: Fixed Issue #59 which showed a rather strange problem with longer space separated lists of font-family values being so slow to actually stop parsing. - BUGFIX/IMPROVEMENT: Fixed Issue #48. ``CSSParser.parseUrl()`` uses the defined fetcher of this parser *for the initial stylesheet* at url too and not just the imported sheets *from* this sheet. - BUGFIX: Fixed Issue #50 which prevented cssutils parsing the acid2.css file correctly. Problem were selectors starting directly with ``[class]`` (an attribute selector). + **API CHANGE (major)** (Known) named colors are parsed as ColorValue objects now. These are the 16 simple colors (black, white, etc) and `transparent` but not all Extended color keywords yet. Also changed ``ColorValue.type`` to ``Value.COLOR_VALUE``. ColorValue has additional properties ``red, green, blue, alpha`` and ``colorType`` which is one of IDENT, HASH or FUNCTION for now. + API CHANGE (minor) Removed already DEPRECATED ``cssutils.parse`` and ``CSSParser.parse``. Use the more specific functions/methods ``parseFile parseString parseUrl`` instead. Removed already DEPRECATED ``cssutils.log.setlog`` and ``.setloglevel``. Use ``.setLog`` and ``.setLevel`` instead. Removed already DEPRECATED ``cssutils.ser.keepUnkownAtRules`` (note the typo). Use ``.keepUnknownAtRules`` instead. - IMPROVEMENT: Added validation profiles for some properties from `CSS Backgrounds and Borders Module Level 3 http://www.w3.org/TR/css3-background/`__, `CSS3 Basic User Interface Module http://www.w3.org/TR/css3-ui/#resize`__, `CSS Text Level 3 http://www.w3.org/TR/css3-text/`__ mainly `cursor`, `outline`, `resize`, `box-shadow`, `text-shadow` license --- cssutils is published under the LGPL version 3 or later, see http://cthedot.de/cssutils/ If you have other licensing needs please let me know. download For download options see http://cthedot.de/cssutils/ cssutils needs Python 2.4 and higher or Jython 2.5 and higher (tested with Python 2.7.1(x64), 2.6.5(x64), 2.5.4(x32), 2.4.4(x32) and Jython 2.5.1 on Win7x64 only) Bug reports (via Google code), comments, etc are very much appreciated!

ANN: cssutils 0.9.8a1
what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) about this release -- 0.9.8a1 is an early alpha release. Please note the *major* changes in the css value API. main changes + **API CHANGE (major)** replace CSSValue with PropertyValue, Value and other classes. NEW CLASSES: :class:`cssutils.css.PropertyValue` replaces CSSValue and CSSValueList - is iterable (iterates over all single Value objects which in soruce CSS might be separated by , / or - a comma separated list of IDENT values is no longer handled as a single String (e.g. ``Arial, sans-serif``) :class:`cssutils.css.Value` replaces CSSPrimitiveValue with separate ``value`` and ``type`` info (value is typed, so e.g. string for e.g. STRING, IDENT or URI values, int or float) and is base class for more specific values like: :class:`cssutils.css.URIValue` replaces CSSPrimitiveValue, additional attribute ``uri`` :class:`cssutils.css.DimensionValue` replaces CSSPrimitiveValue, additional attribute ``dimension`` :class:`cssutils.css.ColorValue` replaces CSSPrimitiveValue, additional attribute ``red``, ``green``, ``blue`` and ``alpha`` **TODO: Not yet complete, only rgb, rgba, hsl, hsla and has values use this object and color and alpha information no done yet!** :class:`cssutils.css.CSSFunction` replaces CSSPrimitiveValue function, not complete yet also renamed ``ExpressionValue`` to :class:`cssutils.css.MSValue` with new API - IMPROVEMENT/CHANGE: Validation of color values is tighter now. Values like ``hsl(1, 2, 3)`` do not validate as it must be ``hsl(1, 2%, 3%)``. This mostly effects HSL/A and RGB/A notation. - **IMPROVEMENT**: New Value parsing and API accelerate parsing of style declarations which take about 20-30% less time now. Of course this depends on the complexity of your styles. + BUGFIX: fixes issue #41, #42, #45, #46 PropertyValue.value returns value without any comments now, else use PropertyValue.cssText - FEATURE: ``cssutils.replaceUrls()`` accepts as first argument a `cssutils.css.CSSStyleSheet` but now also a :class:`cssutils.css.CSSStyle license --- cssutils is published under the LGPL version 3 or later, see http://cthedot.de/cssutils/ If you have other licensing needs please let me know. download For download options see http://cthedot.de/cssutils/ cssutils needs Python 2.4 and higher or Jython 2.5 and higher (tested with Python 2.7.1(x64), 2.6.5(x64), 2.5.4(x32), 2.4.4(x32) and Jython 2.5.1 on Win7x64 only) Bug reports (via Google code), comments, etc are very much appreciated!

what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) about this release -- 0.9.7b3 is a beta release but quite stable. main changes 0.9.7b3 100620 + API CHANGE: Changed parameters of script/utility function ``csscombine``. - parameter ``resolveVariables=True`` now (default was ``False`` before) - ``minify = True`` will not parse Comments at all. This is not really a change as comments were not kept in a minified stylesheet anyway but this may speed up stylesheet combination a bit + **PERFORMANCE/IMPROVEMENT**: Added parameter ``parseComments=True`` to CSSParser. If parsing with ``parser = cssutils.CSSParser(parseComments=False).parse...`` comments in a given stylesheet are simple omitted from the resulting stylesheet DOM. + **PERFORMANCE**: Compiled productions in cssutils tokenizer are cached now (to clear it use ``cssutils.tokenize2._TOKENIZER_CACHE.clear()``) which results in a slight performance improvement.

what is it
--

about this release
--
0.9.7b1 is a beta release but quite stable now I guess...
main changes
0.9.7b1 optimizes handling speed of CSSVariables *a lot*...
changes
+ **API CHANGE**: Child objects like the ``cssRules`` of a
``CSSStyleSheet`` or ``CSSMediaRule`` are no longer kept after resetting
the complete contents of an object (setting ``cssText``). This should
not be expected anyway but if you relied on something like the following
please beware::
sheet = cssutils.parseString('a { color: red}')
initial_rules = sheet.cssRules
sheet.cssText = 'b { color: green}'
# true until 0.9.6a6: assert sheet.cssRules ==
initial_rules, but now:
assert sheet.cssRules != initial_rules
+ **IMPROVEMENT**: Massive speed improvement of handling of
CSSVariables of a stylesheet which due to naive implementation was
unbelievable slow when using a lot of vars... Should now scale a lot
better, about factor 5-20 depending of amount of variables used.
+ IMPROVEMENT: Fair amount of refactoring resulting in a bit speed
improvement generally too
+ CHANGE: If a CSS variable should be resolved
(``cssutils.ser.prefs.resolveVariables == true``) but no value can be
found a WARNING is logged now. Should be an ERROR actually but as
currently lots of fake errors are reported would probably hurt more
than help. A future release might improve this.
+ BUGFIX: Syntax of value of CSS Fonts Module Level 3 ``src``
property now validates if local font name is given with a quoted name,
e.g.: ``src: local('Yanone Kaffeesatz')``

E.g. if setting ``cssutils.css.CSSStyleRule.selectorText`` the underlying ``cssutils.css.CSSStyleRule.selectorList`` object is swapped to a new ``SelectorList`` object. This should be expected but cssutils until now kept the exact same object and changed its content *in-place*. Please be aware! (Also the strange ``_absorb`` method of some objects is gone which was used for this.) + **API CHANGE (minor)**: Renamed ``cssutils.ser.prefs.keepUnkownAtRules`` to ``cssutils.ser.prefs.keepUnkownAtRules`` due to misspelling, see Issue #37. A DeprecationWarning is issued on use. + API CHANGES (minor): - ``cssutils.css.CSSImportRule.media`` and ``cssutils.css.CSSMediaRule.media`` are now writable (setting with a string or ``cssutils.stylesheets.MediaList``) - msg level when setting ``cssutils.stylesheets.MediaList.appendMedium`` changed to INFO (was WARNING) - ``str(cssutils.css.CSSStyleRule)`` slightly changed - **IMPROVEMENT/BUGFIX**: Improved distribution: Egg release should no longer include the tests package, source release still should. Also added dependency package for tests (minimock) and removed documenation txt files from distribution (HTML still included of course). This also fixes Issue #36. - IMPROVEMENT: cssutils issues a warning if a page selector is not one of the defined in the spec (``:first``, ``:left``, ``:right``). - IMPROVEMENT: Refactored quite a lot and added a few tests for variables license --- cssutils is published under the LGPL version 3 or later, see http://cthedot.de/cssutils/ If you have other licensing needs please let me know. download For download options see http://cthedot.de/cssutils/ cssutils needs Python 2.4 or higher or Jython 2.5 and higher (tested with Python 2.6.5(x64), 2.5.4(x32), 2.4.4(x32) and Jython 2.5.1 on Win7 64 only) Bug reports (via Google code), comments, etc are very much appreciated!

defined in module Fonts http://www.w3.org/TR/css3-fonts/
+ **FEATURE**: Added ``cssutils.parseStyle(cssText,
encoding='utf-8')`` convienience function
+ **FEATURE** (experimental, request from issue #27): Added
``css.CSSStyleDeclaration.children()`` which is a generator yielding any
known children of a declaration including *all* properties, comments or
CSSUnknownRules.
+ FEATURE: ``CSSStyleDeclaration.insertRule`` also accepts a
``CSSRuleList`` now (same as ``CSSStyleSheet`` which does this for some
time now).
+ FEATURE: Added ``CSSStyleDeclaration.keys()`` method which
analoguous to standard dict returns property names which are set in the
declaration.
- **API CHANGE**: Replaced attribute ``css.Property.parentStyle``
with ``css.Property.parent`` (``parentStyle`` is DEPRECATED now).
+ **BUGFIX**: Improved child and parent node referencing.
+ **BUGFIX**: Parsing of CSSValues with unknown function names with
a specific length of 4 or 7 chars were resulting in a SyntaxErr. Also
parsing of comma separated list of CSS FUNCTION values works now.
+ BUGFIX: Fixed validation problems:
- ``font-family: a b`` (values with spaces in names without
being quoted) are parsed now without emitting an ERROR. These are indeed
valid but discouraged and you should use quotes (more than one space is
compacted to a single space anyway so rather complicated without quotes)
- negative lengths for the ``font-size`` property are now
properly reported as ERRORs
- IMPROVEMENT (minor): cssutils sets the HTTP header ``User-Agent``
now when fetching sheets over HTTP (with e.g. ``cssutils.parseUrl``).
- *FEATURE* (experimental): Added support to at least parse sheets
with Microsoft only property values for ``filter`` which start with
``progid:DXImageTransform.Microsoft.[...](``. To enable these you need
to set::
from cssutils import settings
settings.set('DXImageTransform.Microsoft', True)
cssutils.ser.prefs.useMinified()
text = 'a {filter:
progid:DXImageTransform.Microsoft.BasicImage( rotation = 90 )}'
print cssutils.parseString(text).cssText
a{filter:progid:DXImageTransform.Microsoft.BasicImage(rotation=90)}
This currently is a **major hack** but if you like to minimize
sheets in the wild which use this kind of CSS cssutils at least can
parse and reserialize them.

ANN: cssutils 0.9.6a4
what is it
--
A Python package to parse and build CSS Cascading Style Sheets. (Not a
renderer though!)
about this release
--
0.9.6a4 is an bugfix release.
main changes
- **API CHANGE**: Reverted handling of exceptions (issue #24) as
this did not work with PyXML installed. You may again use ``str(e)`` on
any raised xml.dom.Exception ``e``. Since 0.9.6a0 exceptions raised did
raise a tuple of message, line and col information. Now the message
alone is raised (again). Line and col information is still available as
``e.line, e.col``.
+ BUGFIX: Fixed issues #22 and #23
+ BUGFIX: All examples at
http://www.w3.org/TR/2009/CR-CSS2-20090423/syndata.html#illegalvalues
should work now as expected
- **FEATURE**: Updated some parts to
http://www.w3.org/TR/2009/CR-CSS2-20090423/changes.html#new (most
changes decribed there were already done in cssutils)
- **FEATURE**: New preference option ``keepUnkownAtRules = False``
which defines if unknown atrules like e.g. `...@three-dee {...}`` are kept
or not. Setting this pref to ``False`` in result removes unknown @rules
from the serialized sheet which is the default for the minified settings.

Re: Will multithreading make python less popular?
Hi, But there is something interesting, something like multi processing. But is it a real alternative for multi threading. As i searched it is not, it requires heavy hardware requirements (lots of memory, lots of cpu power). Not necessarily. For the memory, modern operating Systems can ustilize a copy on write semantics in their Applications virtual memory space. That means that after starting a new process with fork(), the new Process shares all physical Memory Pages with the original one as long a none of them writes to wome Memory. The first write is cought by the OS. Then the Page will be copied and the writing process will in future use the new copy of that page while the other one (or eventually many) stay with the original. Multiprocessing needs more Memory than well optimized Multithreading, but it is not as bad as it is often said. For the CPU: There are two things that make the difference here. One ist Context Switching. When the OS switches between two threads of the same Process, it does not need to change the memory lookup table. When switching between Processes that is always necessary. Switching from a Thread of Process A to a Thread of Process B is just like switching from A to B. Using Threads just increases the probability that the OS can do a faster Context Switch. So Threads are faster here, but it is not a too big issue as well. The Second Thing is Communication. With Threds you can simply use variables to communicate between Threads. To Prevent conflicting access to those Variables you will use e.g. mutexes. That can be done with Shared Memory as well. Shared Memory is a bit more difficult to handle than simply using the heap, but again the impact is not really so big. Google uses Processes for the Tabs in Chrome, because that way they get around many Memory Management Problems they would have with Threads or with a singlethreaded reactor. Using Processes is not per se a bad Idea. You pay a bit with Memory and CPU but in many situations you get a much simpler programming model.

Re: what IDE is the best to write python?
Hi, IMHO, scripting languages like Python are generally better suited to working with a text editor than an IDE. I don't understand that, because in my opinion yields IDE = texteditor + (much) more please could you explain (as I'm very interested in user interfaces in general ) Try to think of the operating system as the IDE. At least with Unix and similar systems that is a really powerfull solution. It includes not only vim, bash and make, but also stuff like e.g. ctags, awk, sed, etc. Even python itsself is part of the system and can be used for special purpous utilities like e.g. code generators. If you need User Interface Design, there are quite powerful stand alone tools, like e.g. the QtDesigner which can be used with that OS IDE.

ANN: cssutils 0.9.5final
what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) release --- 0.9.5 had been in development for about half a year and this is the first *final* release for quite some time now - actually the last has been 0.6 ... It is nevertheless definitely not perfect but tests have been expanded, included scripts should all work and all examples on the website have been checked. 0.9.6 will start soon ... main changes 0.9.5 080730 - **API CHANGE**: If a new medium is trying to be appended to a ``MediaList`` already set to ``all`` an ``xml.dom.InvalidModificationErr`` is raised. The exception to this handling is adding ``handheld`` which is a special case for Opera and kept for now. This special handling may be removed in the future. A ``WARNING`` is logged in any case. - **BUGFIX**: Fixed reference error in @import rule preventing change of the used ``MediaList``. - **BUGFIX**: Deeply nested ``CSSImportRule``\ s with different encodings should keep the encoding as defined (via HTTP, parendSheet, @charset etc) now. Therefor ``cssutils.util._readUrl`` does return ``(encoding, enctype, decodedCssText)`` now where ``enctype`` is a number from 0 to 5 indicating which encoding type was used: 0 for encoding override, 1 for HTTP encoding, 2 for BOM or @charset rule, (3 is unused currently), 4 for encoding of the parent sheet and 5 if encoding defaults to UTF-8 as no other information is available. (This may later be done as constants but this function should not be used from programs generally). - **BUGFIX**: Replaced usage of ``WindowsError`` with ``OSError``. I (naively ;) thought ``WindowsError`` at least be present in environments other than Windows but it just results in a ``NameError``... The part of the API which triggered this Exception is an @import rule with an invalid or local (file) URI so should have happened quite rarely anyway. + IMPROVEMENT: Standalone scripts ``csscombine`` and ``csscapture`` are available for programmatic use in ``cssutils.script.csscombine`` and ``cssutils.script.CSSCapture`` res. + IMPROVEMENT: ``cssutils.script.csscombine`` and ``csscombine`` script do use the cssutils log now instead of just writing messages to ``sys.stderr`` + IMPROVEMENT: Optimized and refactored tokenizer (CHARSET_SYM). Note: CSSValue, CSSValueList, and CSSPrimitiveValue and the relevant methods/properties Property.cssValue and CSSStyleDeclaration.getPropertyCSSValue are more or less DEPRECATED and will probably be replaced with interfaces defined in CSSOM.

ANN: cssutils 0.9.5rc1
what is it
--
A Python package to parse and build CSS Cascading Style Sheets. (Not a
renderer though!)
As there have been quite a few bugfixes and also some minor changes this
is a release candidate and not the final release yet.
main changes
0.9.5rc1 080709
- **API CHANGE/FEATURE**: ``The cssutils.log`` may be partly used
like a standard logging log. The following methods are available:
('setLevel', 'getEffectiveLevel', 'addHandler', 'removeHandler') as well
as all messaging calls like 'error', 'warning' etc.
Therefor ``cssutils.log.setloglevel`` has been *DEPRECATED* and
should be used via ``cssutils.log.setLevel``. The old method is still
available though.
``cssutils.log.setlog`` has been renamed to
``cssutils.log.setLog`` but is still available but *DEPRECATED* too.
- **FEATURE**: All three decoders in the codec now have an
additional ``force`` argument. If ``force`` is false, the encoding from
the input will only by used if is is detected explicitely via BOM or
@charset rule.
- **FEATURE**: ``cssparse`` script has new option ``-m --minify``
which results in the parsed CSS to be serialized minified
- **FEATURE**: ``CSSCapture`` and ``csscombine`` are now available
not only as standalone scripts but also via
``cssutils.script.CSSCapture`` and ``cssutils.script.csscombine``
repectively so you can use them programmatically now.
- **BUGFIX**: A space after @rule keyword is added when serializing
minified something like [EMAIL PROTECTED] all{}``. Until now it was
[EMAIL PROTECTED] which is recognized by Safari only and may not be valid
at all.
- **BUGFIX**: Properties of rules set via ``css.CSSStyleSheet.add``
or ``.insert`` were not set properly, e.g. ``parentStyleSheet`` or the
stylesheet handling of new @import rules was buggy.
- BUGFIX: Encountering OSError during resolving @import does not
throw an error anymore but the resulting CSSImportRule.styleSheet will
have a value of ``None``. OSError will probably only happen when using
``parseFile``.
- **BUGFIX/IMPROVEMENT**: A style sheet with ``href == None`` (e.g.
parsed with ``parseString()`` or build completely from scratch) uses
``os.getcwd()`` as its base href now to be able to resolve CSSImportRules.
- **BUGFIX/IMPROVEMENT**: Rewrote ``csscombine`` script which
should be much more stable now and handles namespaces correctly. Nested
imports are still not resolved yet but this may come in the next release.
- BUGFIX/IMPROVEMENT: Added catching of WindowsError to default
fetcher (e.g. is a file URL references a file not present).
- **BUGFIX/CHANGE**: Redone ``csscapture`` script. A few minor
method changes (parameter ``ua`` of ``capture`` has been replaced by
init parameter) and lots of internal improvement has been done.
- CHANGE: ``CSSStyleSheet.add(rule)`` simply appends rules with no
specific order in the sheet to the end of it. So e.g. COMMENTs,
STYLE_RULEs, etc are appended while rules with a specific place are
ordered-in as before (e.g. IMPORT_RULE or NAMESPACE_RULE). Until now
rules of a specific type like COMMENTs were ordered together which does
not really make sense. The ``csscombine`` script needs this
functionality and the resulting combined sheets should be more readable
and understandable now.
- CHANGE: Default URL fetcher emits an ERROR instead of a warning
if finding a different mine-type than ``text/css``.
- a few other changes, bugfixes and improvements
Note:
CSSValue, CSSValueList, and CSSPrimitiveValue and the relevant
methods/properties Property.cssValue and
CSSStyleDeclaration.getPropertyCSSValue are more or less DEPRECATED and
will probably be replaced with interfaces defined in CSSOM. For now use
the properties and methods that handle values as simple strings, e.g.
``Property.value``. As the aforementioned classes are not hardly that
useful anyway this should not be a big problem but please beware if you
use or have used them.

ANN: cssutils 0.9.5b3
what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) main changes 0.9.5b3 - **API CHANGE**: ``parse()`` is *DEPRECATED*, use ``parseFile()`` instead. I know this should not happen in a release already in beta but better now than later and currently both ways are still possible. - **FEATURE'**: CSSStyleDeclatation objects may be used like dictionaries now. The value during setting a property may be a single value string or a tuple of ``(value, priority)`` - **FEATURE**: While reading an imported styleSheet all relevant encoding parameters (HTTP headers, BOM/@charset, etc) are used now as defined in http://www.w3.org/TR/CSS21/syndata.html#charset Additionally a given parameter ``encoding`` for ``parseString``, ``parseFile`` and ``parseUrl`` functions/methods **overrides** any detected encoding of read sheet like HTTP information or @charset rules. Useful if e.g. HTTP information is not set properly. The given ``encoding`` is used for **all** imported sheets of the parsed one too! This is a cssutils only addition to the rules defined at http://www.w3.org/TR/CSS21/syndata.html#charset. - **FEATURE**: A custom URL fetcher may be used during parsing via ``CSSParser.setFetcher(fetcher)`` (or as an init parameter). The so customized parser is reusable (as all parsers are). The fetcher is called when an [EMAIL PROTECTED] rule is found and the referenced stylesheet is about to be retrieved. - **FEATURE**: Added option ``-s --string`` to cssparse script which expects a CSS string to be parsed. - **FEATURE/BUGFIX**: Parsing of CSSStyleDeclarations is improved. Invalid ``/color: red;color: green`` is now correctly parsed as ``color: green`` now. At the same time the until now parsed but invalid ``$color: red`` (an IE hack) is not parse anymore but correctly dismissed! Unknown rules in CSSStyleDeclaration are parsed now. So e.g [EMAIL PROTECTED]; color: red;`` which is syntactically valid is kept completely. - **LICENSE**: cssutils is licensed under the **LGPL v3** now (before LGPL v2.1). This should not be a problem I guess but please be aware. So the former mix of LGPL 2.1 and 3 is resolved to a single LGPL 3 license for both cssutils and the included encutils. - a few other changes, bugfixes and improvements Note: CSSValue, CSSValueList, and CSSPrimitiveValue and the relevant methods/properties Property.cssValue and CSSStyleDeclaration.getPropertyCSSValue are more or less DEPRECATED and will probably be replaced with interfaces defined in CSSOM. For now use the properties and methods that handle values as simple strings, e.g. ``Property.value``.

The traceback is: File pickle.pyo, line 1374, in loads File pickle.pyo, line 858, in load KeyError: 'A' Does anybody know this problem. How this can happen and how can I avoid it? Thanks, Christof -- http://mail.python.org/mailman/listinfo/python-list

what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) main changes 0.9.5b2 - **API CHANGE**: ``cssutils.parseURL`` has been renamed to ``parseUrl`` for consistency with ``getUrls`` or ``replaceUrls``. Parameter ``href`` (before called ``url``) is the first and mandatory parameter now. + **BUGFIX**: Fix the streamreader in the codec: Honor the encoding if one is passed to the constructor instead of trying to detect it from the stream. + **BUGFIX**: Reading referenced styleSheet in CSSImportRule did not succeed as no encoding information is passed along. Encoding of referenced sheets is always retrieved via HTTP or from imported sheet itself. Fixed lots of unchecked cases and simplified exception handling when reading a referenced sheet. + BUGFIX: Setting ``atkeyword`` of @rules checks if it is a valid keyword for the specific rule. E.g. an @import rule accepts [EMAIL PROTECTED] but not [EMAIL PROTECTED] + BUGFIX: Fixed setting ``name`` of CSSImportRule. Setting ``name`` other than with a string results in xml.dom.SyntaxErr raised now + BUGFIX: ``CSSStyleSheet.type`` with a fixed value of text/css and other readonly properties are really readonly now Note: CSSValue, CSSValueList, and CSSPrimitiveValue and the relevant methods/properties Property.cssValue and CSSStyleDeclaration.getPropertyCSSValue are more or less DEPRECATED and will probably be replaced with interfaces defined in CSSOM. For now use the properties and methods that handle values as simple strings, e.g. ``Property.value``.

ANN: cssutils 0.9.5b1
what is it -- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) main changes 0.9.5b1 - **API CHANGE**: ``cssutils.css.CtyleSheet.replaceUrls(replacer)`` has been **DEPRECATED** but is available as an utility function so simply use ``cssutils.replaceUrls(sheet, replacer)`` instead. For the why see ``getUrls(sheet)`` below. - **API CHANGE/FEATURE**: ``parseString`` has a new parameter ``encoding`` now which is used if a ``str`` is given for cssText. Otherwise it is ignored. (patch by doerwalter) - API CHANGE/FEATURE: ``.parse() .parseString()`` and constructor of ``CSSStyleSheet`` have a new parameter ``title`` needed for the cascade (yet to be implemented ;). + **FEATURE**: Referenced stylesheet in an @import rule is read and parsed now if possible. Therefor the ``href`` given during parsing (parameter ``href`` to the ``parse*`` functions is used. It is also properly set on imported rules. The ``name`` property of the @import rule is set as the imported sheets ``title`` property. + **FEATURE**: Added ``cssutils.getUrls(sheet)`` utility method to get all ``url(urlstring)`` values in ``CSSImportRules`` and ``CSSStyleDeclaration`` objects (properties). As this function and the above mentioned ``replaceUrls(sheet, replacer)`` are useful not only for a single sheet but (later) also for a stylesheet list they are not methods of CSSStyleSheet anymore (also because they are not part of the official DOM spec). (patch by doerwalter) + FEATURE: Added ``cssutils.parseURL(url, encoding=None, ...)`` + BUGFIX: Fixes Issue #10, using full ``$LastChangedDate: 2008-03-19 22:47:34 +0100 (Mi, 19 Mrz 2008) $`` in source files breaks code for some locales. Now only in a few files this svn:keywords replacement is used and only to a fixed length without the problematic part. In all other files ``$Id: ANN.txt 1164 2008-03-19 21:47:34Z cthedot $`` is used which also includes simple but sufficient date information. + **BUGFIX/IMPROVEMENT**: Handling of trailing content, WS and comments in rules should be more consistent and properly handled now, added tests. Exception is ``CSSCharsetRule`` where no comments are allowed at all. - TESTS: **Tests need ``minimock`` now!** Install with ``easy_install minimock`` Note: CSSValue, CSSValueList, and CSSPrimitiveValue and the relevant methods/properties Property.cssValue and CSSStyleDeclaration.getPropertyCSSValue are more or less DEPRECATED and will probably be replaced with interfaces defined in CSSOM.

SimpleHTTPServer send wrong Content-Length for text/* on Windows?
hi, I noticed while trying a simple (but still very useful) server based on SimpleHTTP that it does report a wrong Content-Length for text/* files if Windows line-end \r\n is used. Most clients (e.g. browsers) do simply ignore a wrong Content-Length but there are programs that do care and simply abort handling a file given with a wrong Content-Length and not sending enough content afterwards. I had this problem specifically with Prince-XML but that seems to be based on curl which therefor might also be affect other products/libs. I found this via Google: http://mail.python.org/pipermail/python-bugs-list/2005-January/027157.html It seems this is not a new bug and I somehow recall that in an older version of Python (2.4?) it did work. But in 2.5 (also 2.5.1 and 2.5.2) this is not working anymore. Does anyone know if this is maybe being looked into already? I could not find anything in the Python Bug tracker but wanted to ask here first (I actually am not sure if I can add a bug report anyway). Thanks!

No nested @imports are resolved yet and @namespace rules do not work yet though! + **BUGFIX**: Serializing escape sequences add a single SPACE after each escape. This was not present until now so a sequence like \\74 a did come out as \\74a which was not as intended. Also as a SPACE is inserted in any case all escapes are not padded to 6 digits anymore but are only as long as needed. + **BUGFIX**: Handling of illegal selectors is now same as the W3C CSS validator (and according the selector spec - I hope ;). Illegal selectors result the complete rule being dropped. Fixed are the following (edge) cases: ``a/**/b`` Meant was probably a space between a and b (plus maybe the comment) but it MUST be inserted. IE and Safari nevertheless seem to parse this rule as ``a b`` so as if a space would be present. cssutils now parses this selector as intented by the spec as ``ab``. ``a*b`` Again spaces around the UNIVERSAL ``*`` were probably meant by the author. IE and Safari seem to parse this **invalid** selector as ``a b``. cssutils ignores this rule completely! + BUGFIX: ``css.CSSRuleList`` is still a Python list but setting methods like ``__init__``, ``append``, ``extend`` or ``__setslice__`` are added later on instances of this class if so desired. E.g. CSSStyleSheet adds ``append`` which is not available in a simple instance of this class! This has been changed as no validation is possible in CSSRuleList itself. + IMPROVEMENT: Added better ``str`` and ``repr`` to cssutils.serializer.Preferences + IMPROVEMENT: Added position information to some error reportings (Property, CSSMediaRule + some internal changes license --- cssutils is published under the LGPL. download for download options for see http://cthedot.de/cssutils/ cssutils needs Python 2.4 or higher (tested with Python 2.5 on Vista only) bug reports, comments, etc are very much appreciated! thanks, Christof -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
state of XSLT2/XPath2 or XQuery in CPython
hi, I was wondering if there is any way to use XSLT2 or maybe even XQuery with normal CPython. Using Saxon/XSLT2 with Jython is no problem (I have not tried Saxon.NET with IronPython but suspect no problem?) but I could not find any way to use XSLT2 or XPath Features with CPython. All the usual suspects 4suite or libxslt (via lxml) seem to have no support yet. Is there any hope I oversaw something? Would be especially interesting for a WSGI application, so a more or less complicated hack via CPython-Jython-Saxon and back would probably not be very useful (if that is possible at all). thanks!

All the usual suspects 4suite or libxslt (via lxml) seem to have no support yet. Is there any hope I oversaw something? I wouldn't know any implementation. Are you looking for a specific feature? Using Python functions in XPath/XSLT might get you pretty close to XPath2. Almost full XSLT2 Support (minus XML Schema support, IMHO not too useful part of XSLT2) would be the best as writing templates in a general templating lang as XSLT is great if you use the same ones in cross-lang systems which are e.g. usable in Java or Python environment. Especially XPath Support with temporary trees (and not just fragments) is very useful (I know EXSLT is an option, but still not quite as good as XSLT2). Or stuff like sequences in XPAth2 simplifies development quite a bit (I think the following is possible, have not used it in the last weeks though): (a, b, c)[EMAIL PROTECTED]'123'] Or using sequences for ordering stuff like e.g.: in XSLT1: xsl:apply-templates select=a/ xsl:apply-templates select=b/ which in XSLT2 simply is: xsl:apply-templates select=a, b/ I used the Python extension functions some years ago in Pyana and later in LXML which is great but these naturally very much depend on Python then... I know XML and therefor also XSLT seem not the most favourite of tools in the Python community but for e.g. document based systems like CMS systems XML and XSLT is at least in my experience a great combination. thanks Christof -- http://mail.python.org/mailman/listinfo/python-list

If you say I'll be away from the 4th to the 7th and then turn up on the 7th, nearly everyone will wonder why you're back a day early. Actually, I think this illustrates the point about confusion, because in the United States at least, the 4th to the 7th will not necessarily include the 7th. That's why it's common to use circumlocutions like the 4th through the 7th and the 4th to the 7th, inclusive when one wants to be sure.

The Property constructor has only optional parameters now. + **API CHANGE**: Removed experimental class ``SameNamePropertyList`` which was used in ``CSSStyleDeclaration`` and also method ``CSSStyleDeclaration.getSameNamePropertyList``.

ANN: encutils 0.4
Some basic helper functions to deal with encodings of text files (like
HTML, XHTML, XML) via HTTP. Developed for cssutils but looked worth an
independent release.
Download from http://cthedot.de/encutils/
Included are some unittests.
License
Creative Commons License
http://creativecommons.org/licenses/by/2.0/
Functions:
Note: All encodings returned are uppercase.
encodingByMediaType(media_type, log=None)
Returns a default encoding for the given Media-Type, e.g. 'UTF-8'
for media-type='application/xml'. If no default encoding is available
returns None.
getHTTPInfo(HTTPResponse, log=None)
Returns (media_type, encoding) information from the response'
Content-Type HTTP header (case of headers is ignored.) May be (None,
None) e.g. if no Content-Type header is available.
getMetaInfo(text, log=None)
Returns (media_type, encoding) information from (first) X/HTML
Content-Type meta element if available.
getXMLEncoding(text, log=None)
Parses XML declaration of a document (if present) (simplified).
Returns (encoding, explicit).
No autodetection of BOM is done yet. If no explicit encoding is
found returns ('UTF-8', False).
guessEncoding(HTTPResponse, text, log=None)
Tries to find the encoding of given text. Uses information in
headers of supplied HTTPResponse, possible XML declaration and X/HTML
meta elements.
Returns (encoding, mismatch). Encoding is the explicit or implicit
encoding or None and returned always uppercase. Mismatch is True if any
mismatches between media_type, XML declaration or textcontent are found.
More detailed mismatch reports are written to the optional log.
Mismatches are not nessecarily errors! For details see the
specifications..
Plan is to integrate XML autodetection (of BOM) in the next release.
I would very much welcome any feedback about spec compliance, errors or
other problems with the functions (or the tests!).
