While in general it is fine to clean-up any entity IDs
to be US-ASCII alphanumerics (plus some allowed interpunction),
the GenNodes and also keys in object-bindings for diff are
considerd internal interfaces, assuming that any passed
ID symbol is already sanitised and checked. So the
sanitise operation can be skipped. This changeset
adds the same option directly to lib::EntryID,
allowing to create an EntryID that matches
a similar GenNode's (hash) ID.
based on the previous experiments, this adds a fake operation
and a definition frame to hook this operation as pseudo Proc-Layer command
WIP: the invocation itself is not yet implemented.
We need to build a custom invocation pattern for that,
in order to be able to capture the instance-ID of the command
on invocation
NOTE: also, because of #989, we can not bind a time value for this test
over time, we got quite a jungle with all those
shome-me-the-type-of helper functions.
Reduced and unified all those into
- typeString : a human readable, slightly simplified full type
- typeSymbol : a single word identifier, extracted lexically from the type
note: this changeset causes a lot of tests to break,
since we're using unmangeled type-IDs pretty much everywhere now.
Beore fixing those, I'll have to implement a better simplification
scheme for the "human readable" type names....
- remove unnecessary includes
- expunge all remaining usages of boost::format
- able to leave out the expliti string(elm) in output
- drop various operator<<, since we're now picking up
custom string conversions automatically
- delete diagnostics headers, which are now largely superfluous
- use newer helper functions occasionally
I didn't blindly change any usage of <iostream> though;
sometimes, just using the output streams right away
seems adequate.
- simple function to pick up the mangled type
- pretty-printing is implemented in format-obj.cpp
- also move the demangleCxx()-Function to that location,
it starts to be used for real, outside the test framework
while in debugging, it turned out that the short type-prefix
was implemented in a too simplistic way; it fails on stuff
like 'lib::diff::Record<lib::diff::GenNode>'
while I must add, that the whole purpose of these ID functions
is somewhat unclear and needs to reveal itself as we move forward
...while on the train back from FrOSCon.
still the same old problem: we need a better hash function
for generating our Entry-IDs. The default hash function from Boost performs
poor on strings with common prefix and trailing number.
We use a hackish workaround, which is sufficient to avoid collisions
among the first 10000 numbers.
basically this is the well known problem #587
Just it became more pressing with the Upgrade to Jessie and Boost 1.55
So I've pulled off the well known "Knuth trick" to spread the
input data more evenly within the hash domain.
And voilà: now we're able to use 100000 number suffixes without collision
- move the santitise operation up into EntryID's ctor
- turn the recast() operation into a real in-place cast
these changes should be transparent to the existing usages
of EntryID (within the asset framework), but allow for use
as attribute name holder in GenNode, since we're now able
to feed existing name/ID values directly into the ctor
of BareEntryID, without any spurious santitise operation.
using the struct-scheme.hpp and the requirements for
EntryID as a guideline. The goal is to move EntryID
over into the support lib, which means we need to get rid
of all direct proc::asset dependencies. Thus, these generic
ID functions shall form a baseline implementation, while
asset::Struct may provide the previously used implementation
through specialisation -- so the behaviour of EntryID will
not change for the structural assets, but we'll get a more
sane and readable default implementation for all other types.
