Running the [http://epydoc.sourceforge.net/ Epydoc] document generator on a model returns the following error message: {{{ File: c:\dev\python-2.4.2\lib\site-packages\django\db\models\base.py, line 243, in django.db.models.base.Model._collect_sub_objects Lines 246, 247: Improper paragraph indentation }}} Looking at those lines, we find: {{{ def _collect_sub_objects(self, seen_objs): """ Recursively populates seen_objs with all objects related to this object. When done, seen_objs will be in the format: {model_class: {pk_val: obj, pk_val: obj, ...}, model_class: {pk_val: obj, pk_val: obj, ...}, ...} """ }}} The problem appears to be with the extra tabs in the last two lines of that comment. I've fixed it in my local version, but someone may want to fix the version in the repository so it doesn't break for others. adrian     0 0 0 0 0 0

At least for sqlite, the sql row is passed in as args- issue is that __init__ shoots through self._model.fields playing with kwargs prior, doing rather costly exception catching, pulling default values, etc, then *finally* does args processing. If you're dealing in one or two records, this doesn't show up much, but if you're dealing in 53k records (my usage is slightly weird admittedly), it's a pretty heavy slow down. attached is a patch to refactor __init__, knocking around a third off the __init__ cost via refactoring the args/kwargs processing, essentially reversing the actual flow while maintaining the same behaviour as before. Have been using it for a few days, and passes tests; comments welcome, mainly since I need to get this integrated for my uses. adrian (removed)   0 1 0 0 0 0

Short version, attached patch shows 5x boost in dispatch speed; for iteration (just that, no rendering) over 53k records, time drops from ~15.5s to ~11.6s just by cleaning up dispatch.* The internal data structs dispatch is using are still fairly innefficient- scaling will be an issue the more receivers there are for dispatched signals. So... can clean that up further, but there isn't any documentation re: the expectations of dispatcher. For example- order of connection to a signal, must the order be maintained for notifications at a specific sender/signal level? If I connect (in this order) func f1, func f2, both to object("foo") signal Any, must they be notified in order f1,f2? I realize pydispatcher is a seperate project- that said, they've already moved onto 2.0, and there are several 1.0.x's for pydispatcher released already- djangos' bundled copy is still at 1.0.0. Whats the intention? Intending on keeping it in sync, or is it just a fork point? Either way, the attached refactoring is not covered by tests at the moment- mainly since there are no tests in django for dispatcher. Would like to get feedback on the expectations of dispatcher (f1/f2 from above for example) prior to writing those tests, since the implementation (and google for that matter) lack any material on it. Finally, due to the massive number of calls to send (thus to getAllReceivers and friends), normal seperation (getAllReceivers using getReceivers for example) was intentionally broken down a bit- in other words, inlined a few functions. The codes invoked enough that the overheads seperation really isn't worth it, especially if you're not actually using signals for the most part (thus dispatcher is pretty much pure time waste). adrian (removed)   0 1 0 0 0 0

Thus django.template.resolve_variable raises it via {{{ raise VariableDoesNotExist, "Failed lookup for key [%s] in %r" % (bits[0], current) }}} So... it's effectively raising VariableDoesNotExist(msg). Problem here is that a rather large amount of code just catches the exception, and substitutes a different value, TEMPLATE_STRING_IF_INVALID for example- in other words, they don't even *care* about the msg, the exception is just a passing mechanism. Thus the msg creation is pure overhead to most codeblocks I've found in django. Said overhead can add up; a context level lookup ( {{ foo }} for example), raising VariableDoesNotExist results in repr(context), repr'ing all mappings in context- if say your base template is just checking for a var, if so, outputing a queryset, else not outputting it, the current code forces a repr on context, in other words forcing the query to be executed. Which is fairly daft, if pretty much all code just throws out the exception, substituting a different value in. Attached is a patch changing VariableDoesNotExist's __init__ to (self, msg, params=()); via that, can delay the actual msg creation until it's required, making catching the exception just to substitute a different value far cheaper. Within the code, only resolve_variable throws the exception- google code search, nobody else is throwing it, thus it looks pretty safe to change the __init__ to delay the cost. Alternative, just derive NewStyleVariableDoesNotExist from VariableDoesNotExist, and have resolve_variable throw that; either way, it's work being done that isn't needed so should be tweaked. adrian (removed)   0 1 0 1 0 0

The issue is that this work is utterly redundant the second time an attempt is made to resolve the variable- for loops for example. This patch splits out a Variable class which does the common setup work up once in init, with a resolve method to do the actual resolution against a context. The actual resolve is still a good chunk of time, but for my particular usage scenario (3 level deep for loop being the main cost), this shaves just shy of 25% of the runtime off via killing the redundant work. From a backwards compatibility standpoint, there isn't any issue- resolve_variable just becomes {{{ def resolve_variable(arg, context): return Variable(arg).resolve(context) }}} which admittedly will be slightly slower then whats in place now for simple lookups- this is offset by the greater efficiency of Variable usage within default tags/templates, and via killing off a quadratic op in resolve_variable- currently, it splits the arg, then does poplefts on the list. Problem there is that python lists are literal arrays; you delete the first item, every item after has to be moved one to the left, thus quad in execution. Fortunately var depth isn't usually deep enough for it to rear its head. jacob (removed) performance 0 1 0 0 0 0

This is a bit faster; that said, I'm wondering why the forced conversion- sqlite stores data in utf8, if {{{ Database.text_factory = str }}} ware set, the whole decoding/encoding would be bypassed, and the native encoding (utf8) would be passed back. In terms of performance, using {{{ Database.text_factory = lambda s:s.decode("utf-8") }}} gains are dependant upon the column types; greater # of non-text fields, greater the gain. Real gain is via turning off the encode/decode and using str directly (underlying utf8); same gain in terms of avoiding extra inspection, but avoids all the extra work. Only downside to either change I can see is that raw sql queries would return str instead of sqlites unicode. Not really sure if this is an actual issue however (don't see any other such limitation in the backends). Patch is attached for the encode/decode variant; unless there are good reasons, would just bypass the encoding/decoding entirely. adrian (removed) unicode-branch 0 1 1 0 0 0

One can use trial, but that requires setting up a few extra envvars- it's not hard to do, it's just a fair bit of a hit to the workflow (at least it is for me). Attached is a patch mangling runtests.py so that it takes modeltests.model1, regressiontests.regresion1 args instead of just model names- additionally, can take modeltests.* or regressiontests.* to enable all tests for that namespace (basically). So for example- {{{ python tests/runtests.py --settings=settings -v 1 basic }}} becomes {{{ python tests/runtests.py --settings=settings -v 1 modeltests.basic }}} Upshot of that slightly larger invocation, is that regressiontests, django.contrib, any namespace can be specified now- {{{ python tests/runtests.py --settings=settings -v 1 regressiontests.bug639 python tests/runtests.py --settings=settings -v 1 django.contrib.sessions }}} adrian (removed)   0 0 0 0 0 0

Aside from the fact it's forcing 2(n-1) repr when n repr would suffice, equality protocol exists exactly for usage in cases like this. The repr abusage there covers up a few things- 1) bad object implementations that have taken the time to flesh out repr, but not __eq__ which isn't really covering up. Tough cookies frankly (__eq__/__ne__ are simple methods to implement, and are needed elsewhere- hashing for example). 2) Objects that repr to the same, but have an __eq__ that says they differ. If __eq__ says it differs, it differs- using an alt equality method is dodging whatever reason the original author had for having __eq__ compare differently (exempting if they just didn't implement __eq__, which is scenario #1).

So... question is, why should !ForNode use it? Have yet to find any comments/explanation code wise, only thing I can *guess* is that someone was trying to extend !DebugNodeList.render_node behaviour down through a for; as said, this hurts the common case. Realize the first reaction is likely going to be another "micro-optimization is evil" comment; thing is, while it's not a huge gain like say removing dispatch.send invocations from Models.*, it's a constant waste occuring in any !NodeList.render (which are common enough). Usual usage scenario I'm abusing for testing pegs it as a constant 1.4s hit against trunk 64s (26s if using my misc patches sitting in tickets); might not seem like much, but it's yet another spot where it's spinning it's wheels without reason.

Short version; dispatch is a slow beast- basic design flaws follow * signals are sent regardless of whether or not something is listening * every emit/send requires searching for any matching sender, and matching signal receiver- additionally, requires looking up Any. The listeners change only when a new connection is added/goes out of scope, doing it every time at send is inefficient * signals, while singleton instances, aren't used for anything more then effectively a constant; meaning all of the logic is shoved into dispatcher; due to this, there is no easy place to define the set of args sent to listeners, it's completely dependant on each send invocation using an adhoc agreed to standard. Due to a signal being just a constant, there is no easy space to make signals faster via calculating up front the receivers to notify (it could be implemented in dispatcher.*, but that code is already ugly/messy, and feels a bit fragile). Attached is a patch adding the basic intelligence to signals; this folds in ticket #4521 (basic signal class with __str__/__repr__). Roughly, adds the following logic: * for 'smart signals' (signals that are more then just constants), adds (enable|disable)_sender(sender) methods. In dispatcher.connect, if the signal is 'smart', signal.enable_sender(sender) is invoked- basically notifies the signal that something is actually listening, and what specifically is listening. In disconnect, a amtching disable_sender(sender) is added- same thing (notify that a receiver is going away). * Tracking of all known 'smart signals'; this is used by Any, to multiplex enable_sender calls down into each individual signal * a pre/post signal class, and func to generate the paired signals. This one is a bit more complex, and is the initial gain (aside from cleanup )from this refactoring. Basically, it modifies the sender on the fly, injecting pre/post dispatch… nobody (removed) performance 0 1 0 0 0 0

Basically, proposing that Context.(push|update) return the newly added scope, and that Context.pop() returns the removed scope (for reasons of API symmetry mainly). The main reasoning behind this is that it's useful to bypass Context when doing more then setting a key or two- Context's api isn't as full featured as dicts (nor necessarily should it be). Right now, can do similar tricks via passing in the new scope to update, but that's not particularly friendly/obvious- alternative being reaching into the Context internal stack, which again, isn't very friendly (screws encapsulation anyways). Bypassing context for doing scope updates is actually fairly useful- very least, access to .clear() is a nice way to avoid continual pop/push on the stack per iteration. nobody (removed)   0 1 0 0 0 0

Problems follow: * wind up continually generating larger and larger strings as data is added on, percolating it's way up to the actual template.render. This isn't totally friendly to performance (specifically has a knack for forcing the alloc pool to expand repeatedly). * Data is already ready to be sent, but it's locked away in the template- basically, template rendering tries to build a final string of all contents- until that's finished nothing is sent * Said "final string of all content" means that django winds up being more memory hungry, pretty much without any reason. A backwards compatible solution is the introduction of an iter_render method to Node, that yields finalized chunks as they're available- this doesn't mean yielding each char as it's available, means (for a ForNode for example), yielding each chunk of data for iteration; via this approach, Template.iter_render has chunks of data percolate up as they're available, instead of just one big ass string at the end. Attached is a patch implementing iter_render, and converting existing tags/templates/involved codepaths over to iteration where sane; some node rendering still collapse internally (filter expressions primarily, although will be targeting those later). This patch includes the patch from ticket #4523 (isinstance usage there gets ugly when a lot of items are passing through it). Final other change worth noting- changes the base http so that it's no longer flushing after every single write during content dumping. Reason behind this should be fairly obvious- fine if you're writing a single item, sucks if you're writing a few hundred. One point of potent… adrian (removed) performance 0 0 0 0 0 0

This avoids potential infinite loops at runtime.

Attached is a patch that converts the check over to verifying the resultant (as in, full MRO) render/iter_render, and adds an option to specifically disable the verification where needed. adrian (removed)   0 1 0 0 0 0

Flaw with it is that enumerate continues to increase the index even if you change the list under it's feet- in other words, you skip the item immediately following a deletion. One reason list comps are usually better in this case (although dependant on # of items and deletions of course). So... that should be using list.remove and catching ValueError where it doesn't exist. Quite a bit faster due to shifting comparison to cpy, and stopping the search after the first find. Clarifying the latter, a quick read of Signal.connect shows it disallows redundant connections to the same 'key'; meaning that the enumerate code in place right now is daft for continuing it's search for more to wipe- essentially a mismatch between connect/disconnect (guessing it crept in when someone tweaking signal.connect to disallow redundant registrations). basically convert {{{ for idx, (r_key, _) in self.receivers: if r_key == lookup_key: del self.receives[idx] }}} into {{{ try: self.receivers.remove(lookup_key) except ValueError: pass }}} 'nuff said. nobody (removed)   0 0 0 0 0 0

This functionality was broken in r12721 and doesn't currently work in Django 1.2. Example: {{{ def get_default(): return SomeModel.objects.get(id=5) class Test(models.Model): foo = models.ForeignKey(SomeModel, default=get_default) }}} This model should display in the admin with the default !SomeModel already selected in the drop-down box. The !ModelForm code that does this seems to have been confused by the changes made in r12721. The code in the Field class in django/db/models/fields/!__init!__.py could also do with a cleanup: formfield() first checks has_default() before calling get_default(), which also checks has_default(). The patch in r12721 adds to this duplication of logic by checking if self.default is callable, which is also done by get_default(). nobody 3point2   0 0 0 0 0 0

For example, consider an invoice: models.py: {{{ class Invoice(models.Model): # fields like customer_name, etc total = models.DecimalField(max_digits=11, decimal_places=2) def update_total(self): self.total = sum([x.cost for x in self.invoiceentry_set.all()] class InvoiceEntry(models.Model): invoice = models.ForeignKey(Invoice) item = models.CharField(max_length=100) cost = models.DecimalField(max_digits=11, decimal_places=2) # etc }}} When clicking "save" in the admin after editing or adding an invoice in the admin interface, there is no way to have the invoice update its total using the update_total method. Overriding the save() method on the Invoice model doesn't help, because it is called before the related !InvoiceEntries are created and saved. I supposes the functionality I want could be implemented by overriding the save() method for the !InvoiceEntry model and have it update the total of the parent instance, although this seems a little inelegant as the Invoice instance would then be updated and saved once for every invoice entry created or edited. I suggest adding a "post_save" option to the !ModelAdmin class, which will be called once all related objects have been saved. Please consider the attached patch. It allows the following: admin.py: {{{ class InvoiceAdmin(admin.ModelAdmin): def post_save(self, instance): instance.update_total() admin.site.register(Invoice, InvoiceAdmin) }}} With the patch, the post_save method above is called after the invoice and all its related entries have been created and saved. If this is considered for inclusion into Django, I'd be happy to modify the patch to include documentation. Vasili pandres 3point2   0 1 1 1 1 0

Now I add this to my Payment !ModelAdmin: {{{ list_filter = ["received_by"] }}} If I use a query string like "?received_by!__id!__exact=2" on the payment changelist view, there is no problem. This is the form that the admin itself uses for the filter. Using something more implicit like "?received_by!__id=2" works fine too. However, using "?received_by!__pk=2" raises !SuspiciousOperation. This was introduced by the security fix in r15031. The lookup_allowed method in admin/options.py explicitly makes an exception for "!__id" (or whatever the primary key attribute of the model is explicitly called), but it doesn't allow direct use of the 'pk' shortcut. The point of the security fix was to only allow lookups specified by list_filter. However, in its current form it also causes the query string syntax to diverge from the documented lookup syntax https://docs.djangoproject.com/en/1.4/topics/db/queries/#the-pk-lookup-shortcut . I suggest allowing use of the pk shortcut in the query string. I would be happy to write a patch for this if the developers agree it should be fixed. nobody 3point2   0 0 0 0 0 0

However, in my application the lookup that needs to be whitelisted generates a huge filter widget as it contains thousands of instances. It would be helpful if I could whitelist the exact lookup I need to link to without having to generate the filter widget itself. Something like {{{ class MyModelAdmin(ModelAdmin): allow_lookup = ["fieldname__id__exact"] }}} would do. If the developers agree this is useful functionality, I could write a patch.

When I tried to do so with "manage.py runserver" a command feedback appeared reporting the next error: [[Image(http://s21.postimg.org/e362aaql3/traceback_error.png)]] In line 279, the code indicated that it was a problem with the encoding of a character.

Then I started digging in the code and I found the file with the error "autoreload.py": [[Image(http://s21.postimg.org/5v44payon/autoreload_before.png)]] The problem occurred with the method "os.spawnve" that executes the program path in a new process.

The arguments "sys.executable" & "args" didn't present any errors. It was a clean print. "new_environ", that's another story. It presented a new error indicating that a Unicode value (\u202a) couldn't be decoded by the function charmap. I searched this particular Unicode and it's used for indicating '''directional embedding''' (more of this at: [http://unicode.org/reports/tr9/#Directional_Formatting_Codes]). It appears that this particular Unicode character isn't supported in Windows, that includes the 3 versions indicated in the summary.

See here, where `delta` is to be supplied by `timesince`: {{{ #: templatetags/humanize.py:190 #, python-format msgctxt "naturaltime" msgid "%(delta)s ago" msgstr "vor %(delta)s" }}} This produces erroneous translations in German (and probably other inflectional languages, too). "3 days, 12 hours ago" is translated by Django as {{{ vor 3 Tage, 12 Stunden }}} but the correct translation is (with dative inflection) {{{ vor 3 Tagen, 12 Stunden }}} "3 Tage" is correct for `timesince`, but for `naturaltime` it must become "3 Tagen". Unfortunately, the assumption that these translations can simply be pieced together from translated bits in timesince.py is mistaken. I apologise if this isn't the right channel.
