Undesirable entries in typedefs list
I noticed that doing pgindent with the current typedefs list available
from the buildfarm caused a lot of havoc in what had been stable code.
Looking into the reasons, it seems that:
(1) "bool" is no longer listed as a typedef name (probably because
stdbool.h makes it a macro instead);
(2) "abs", "boolean", "iterator", "other", "pointer", "reference",
"string", and "type" all now are listed as typedef names.
It's probably okay to treat "boolean" as a typedef, but all those others
are complete disasters. Anyone know where they're coming from?
As for "bool", we could probably deal with that most reliably by
having pgindent add it as a special case. Maybe we could get it
back in there by having some trailing-edge buildfarm member
contribute typedefs, but that seems like a solution with a rather
limited half-life.

Semi informed theory: LLVM? I think I'd configured one of the LLVM
animals to collect typedefs, but that might have been a bad idea...

Could we combine the list of typedefs with one manually maintained
in-tree?

That was my first thought as well, since this seems to have changed
quite recently. I don't think it's a bad idea to be collecting typedefs
from something that compiles that code, because otherwise our own
typedefs in that area won't be known.

Perhaps. We might need a manually maintained blacklist, as well.

The number of typedefs we actually use is fairly small (~5-7), so we
could realistically maintain the them manually.
I'm about to head out, but afterwards I'm going to check what the
typedefs collected actually are when LLVM is enabled.

It's indeed from llvm:
<3><5201>: Abbrev Number: 4 (DW_TAG_typedef)
<5202> DW_AT_name : (indirect string, offset: 0x8a0a4): string
<5206> DW_AT_decl_file : 13
<5207> DW_AT_decl_line : 74
<5208> DW_AT_type : <0x3896>
which basically references std::string
<3><3896>: Abbrev Number: 24 (DW_TAG_class_type)
<3897> DW_AT_name : (indirect string, offset: 0x2db87): basic_string<char, std::char_traits<char>, std::allocator<char> >
<389b> DW_AT_byte_size : 32
<389c> DW_AT_decl_file : 12
<389d> DW_AT_decl_line : 77
<389e> DW_AT_sibling : <0x51fc>
Given that the PG code shouldn't refer to this, I think we might be able
to limit things by specifying --dwarf-depth=3 to the objdump output.
I've attached the difference between a objdump typedefs list roughly
equivalent to what the buildfarm uses. There's no difference when not
using llvm.
I'm a bit uncomfortable relying --dwarf-depth=3, with 3 being determined
purely experimentally though.

Andres Freund

Are you referring to Section 3.4? That's something different afaict. Or
which bit are you thinking of?
See e.g. https://sourceware.org/bugzilla/show_bug.cgi?id=22250
"
Another addition "depth" starts counting from zero. Zero usually is the
first DIE (compilation_unit or partial_unit). Specifying --dwarf-depth=0
will only print the Compilation Unit headers, followed by a blank line
and no ... markers. Unless --dwarf-depth is given with a non-zero
argument, then only a blank line is printed.
"
My understanding is that it controls through how many levels of nesting
in type definitions objdump recurses through. The type of typedefs we
really care about are going to be at the global level. Which should make
them available at dwarf-depth=2. Then we have a few typedefs which are
solely done inside functions, which is why we need dwarf-depth=3.

Andres Freund

simply, assuming you have identified all the offending tokens.

Oh, so it does.
Here's a patch to pgindent which I think will do what you want fairly
simply, assuming you have identified all the offending tokens.
Hm, this does not work for me (with perl 5.10.1), I get syntax errors like
Not enough arguments for map at src/tools/pgindent/pgindent line 64, near "abs allocfunc iterator other pointer printfunc reference string type )"
(Might be a runaway multi-line () string starting on line 63)
syntax error at src/tools/pgindent/pgindent line 64, near "abs allocfunc iterator other pointer printfunc reference string type )"
Execution of src/tools/pgindent/pgindent aborted due to compilation errors.
After reading the perlfunc man page I changed
-my %blacklist = map { "$_\n" => 1 }
+my %blacklist = map { +"$_\n" => 1 }and then it seems to work, but man this is an ugly language :-(

Yes, there are lots of quirks that can make it fun to deal with.
Thanks for fixing and committing.
