Still very much in flux, but some treewide cleanups in there...
And I've been wondering if "join" is a better word than
"associate" to denote the relationship between inboxes
and coderepos.
But "join" (even if we use join(1) internally) probably
implies strict relationships, whereas our current "associate"
is always going to be fuzzy due to patchids being fuzzy
and blobs OIDs being abbreviated in patches.
I'm also thinking about moving --associate-* CLI switches
into suboptions (e.g. what getsubopt(3) supports), so:
--associate=aggressive,prefixes=patchid+dfblob
But Perl doesn't ship with getsubopt(3) emulation
out-of-the-box
Eric Wong (18):
cindex: check `say' errors w/ close or ->flush
tmpfile: check `stat' errors, use autodie for unlink
cindex: use `local' for pipes between processes
xap_helper_cxx: use write_file helper
xap_helper_cxx: make the build process ccache-friendly
xap_helper_cxx: use -pipe by default in CXXFLAGS
xap_client: spawn C++ xap_helper directly
treewide: update read_all to avoid eof|close checks
spawn: don't append to scalarrefs on stdout/stderr
cindex: imply --all with --associate w/o -I/--only
cindex: delay associate until prune+indexing finish
xap_helper: Perl dump_ibx respects `-m MAX'
cidx_xap_helper_aux: complain about truncated inputs
xap_helper: stricter and harsher error handling
xap_helper: better variable naming for key buffer
cindex: do not guess integer maximum for Xapian
cindex: rename associate-max => window
cindex: support --associate-aggressive shortcut

We actually need to rely on autodie `close' to check for errors,
since error-checking with `say' is not useful due to perlio
write buffering. We'll also stop relying on `say ... or die'
since it's needless noise.
Fixes: 19f9089343c9 (cindex: drop redundant close on regular FH)

`stat' can fail due to bugs on our end or ENOMEM, but there's
no autodie support for it. So just die if `unlink' fails, since
the FS wouldn't be usable for tmpfiles in that state, anyways.

We can let these pipes get auto-closed upon leaving the process
subroutine scope.

PublicInbox::IO already gets loaded by PublicInbox::Spawn, so
there's no avoiding it even if we want fast startup time :<
But startup time for this piece will be less relevant in the
near future...

We need to have stable filenames and separate compilation
from the linkage stage for ccache to hit. So avoid the use
of a temporary directory and instead rely on a lock file to
guard against parallel builds.

-ggdb3 is already used for g++ and clang, and -pipe is supported
by clang even if it's a no-op. So just use it to speed up g++
since it saves me 30-40ms.
We'll also get rid of the explicit `-O0' since it's the default
for both clang and g++.

No need to suffer through an extra dose of slow Perl load times
when we can drive the build in the big parent Perl process and
get the executable path name to pass to spawn directly.

read_all can be expanded to support FIFOs/pipes/sockets where
read-until-EOF behavior is desired. We can also rely on
wantarray to support splitting on EOL markers, but it's
hard-coded to support only `$/ eq "\n"' since (AFAIK)
it's the only way we use the wantarray form `readline'.

None of our current code relies on it, and I can't imagine it's
something we'd need in the future, actually... This keeps the
door open for relying more on Spawn in TestCommon.

I just forgot to use --all with --associate and it wasn't
easily apparent what was wrong. We'll also show some extra
progress while we're at it.

Prune can get rid of invalid commits while indexing can add new
candidates for association, so we don't dump coderepo roots for
association until those are squared away. However, we can dump
inbox info since we don't touch inboxes while -cindex is running.

The C++ version does, so the Perl/XS version should, too;
even if we intentionally avoid using it right now.

We'll require an error stream for dump_ibx and dump_roots
commands; they're too important to ignore. Instead of writing
code to provide diagnostics for errors, rely on abort(3) and the
-ggdb3 compiler flag to generate nice core dumps for gdb since
all commands sent to xap_helper are from internal users.
We'll even abort on most usage errors since they could be
bugs in split2argv or our use of getopt(3).
We'll also just exit on ENOMEM errors since it's the easiest way
to recover from those errors by starting a new process which
closes all open Xapian DB handles.

We'll use `kbuf' for the search object key, since we already use
the `fbuf' term in `struct fbuf'. This also adds an extra check
for open_memstream(3) failures in case of ENOMEM.

We can return an array to allow the caller to omit the internal
`-m' arg entirely. We'll also allow any non-positive values to
mean there's no limit; and we'll defer the "unlimited" case to
the XapHelper implementation. This frees us of having to deal
with mismatches between Perl and Xapian if Xapian was compiled
with 64-bit docid support and we're stuck on a 32-bit Perl
build.

"window" is probably a better term since it's an inexact thing
to match on.

This is shorthand to enabling --associate with the most
aggressive (and time-consuming) options available, starting from
the Unix epoch and having an unlimited window to join on.
