9bcbd93ac5 Change translation of implicit throws (issue #1589). 
This adds a new invalid instruction that is used for encoding
implicit throws that are emitted by the compiler. This makes it
possible to distinguish such runtime errors from user-provided,
explicit throws.

94b092d87c Provide fall-back method for contract lookup 
Properly, contracts are now looked up via <source>:<contract> identifiers
called "fully qualified names."  As a modicum of backward-compatibility,
failure on a lookup is now backed up by seeing if the ":" exists at all,
and if it doesn't, then the known contracts are scanned for any matching
contract name.

5a2331a9f6 Remove checkLibraryNameClashes() 
The library name clash checker throws errors when two libraries of the
same name are spotted.  In a previous commit, this function was
rewritten to use fully-qualified names instead, which makes it redundant
to the checker for multiply-declared identifiers.  Since it no longer
serves a clear purpose, the function is being dropped.
 2017-01-16 12:32:58 -05:00
Rhett Aultman
1f30982ab5 Use fully-qualified names for linking, too 
Using libraries leaves behind a library link reference in the binary
which the linker must later resolve.  These link references were still
being generated by name and not by fully-qualified name.  This would
lead to a link-time collision between two libraries having the same
name but in different source units.

This change changes linker symbols over to fully-qualified names,
which resolves that issue.  This does potentially introduce a new
problem, which is that linker symbols appear to be limited to 36
characters and are truncated.  Storing paths extends the average
symbol size, and it would be great if truncation was from the tail
rather than the head.

85c55c796a Remove unique error for contract collision 
Because contracts are uniquely identified by their source unit, there
is no need for a unique error for this; it's actually covered by the
checker for double-declaration of identifiers.

e3b0827721 Push the error instead of throwing it 
Throwing a CompilerError on multiple contract definition violates the
expectations of the test suite, which thinks that compile() will
return false if the code can't compile.  This brings contract
collision reporting in line with most of the other errors.
 2017-01-16 12:32:57 -05:00
Rhett Aultman
8f25bd54e3 Drop ':' if the source file name is empty 
A large number of tests compile contracts while passing in an empty
string for the source name.  This leads to it being keyed by the name
":<contract>", while the tests try to look it up under the name
"<contract>".  This change resolves that issue by dropping the ':' in
cases where there is, effectively, no source file to prepend anyway.
 2017-01-16 12:32:57 -05:00
Rhett Aultman
071b936b37 Only avoid collision if it's the same file 
@chriseth had suggested that it would be better if contracts were
referenced in a file:contract notation, and that we output .bin files
that prepend original path names if necessary to avoid a collision.

This commit is mostly a draft; it still needs to be run through the test
suite.

f3a84eab91 Error out when contracts collide on name 
The previous behaviour, courtesy of the [] operator in std::map, would
uncritically store a new ContractDefinition in m_contracts even when a
ContractDefinition already existed.  This "resolved" collissions on contract
names by clobbering the original one with the new one, and could lead to
scenarios where the clobber would only be discovered when the original
ContractDefinition could not be found or referred to, which was an unhelpful
InternalCompilerError.

This change checks the m_contracts map for a collision first and will not let
the ContractDefinition be changed to a new one once it's set, throwing a
CompilerError with information about the conflict.
