The dynamic generation of the linker version script for libnotmuch
exports has grown rather complicated.
Reverse the visibility control by hiding symbols by default using
-fvisibility=hidden, and explicitly exporting symbols in notmuch.h
using #pragma GCC visibility. (We could also use __attribute__
((visibility ("default"))) for each exported function, but the pragma
is more convenient.)
The above is not quite enough alone, as it would "leak" a number of
weak symbols from Xapian and C++ standard library. Combine it with a
small static version script that filters out everything except the
notmuch_* symbols that we explicitly exposed, and the C++ RTTI
typeinfo symbols for exception handling.
Finally, as the symbol hiding test can no longer look at the generated
symbol table, switch the test to parse the functions from notmuch.h.
The feature test code should test the build environment, and none of
the compat code should interfere with that. Don't include compat.h
from the feature test source. There should be no functional changes
here, but this is just the right thing to do.
Commits 9db2145272 ("lib/gen-version-script.h: add getline and
getdelim to notmuch.sym if needed") and 3242e29e57 ("build: add
canonicalize_file_name to symbols exported from libnotmuch.so")
started exporting compat functions from libnotmuch so that the cli
could use them. But we shouldn't export such functions from the
library. They are not part of our ABI. Instead, the cli should include
its own copies of the compat functions.
From a UI perspective this looks similar to what was already provided
for from, subject, and mid, but the implementation is quite
different. It uses the database's list of terms to construct a term
based query equivalent to the passed regular expression.
'quite' on IRC reported that notmuch new was grinding to a halt during
initial indexing, and we eventually narrowed the problem down to some
html parts with large embedded images. These cause the number of terms
added to the Xapian database to explode (the first 400 messages
generated 4.6M unique terms), and of course the resulting terms are
not much use for searching.
The second test is sanity check for any "improved" indexing of HTML.
The index(3) function has been deprecated in POSIX since 2001 and
removed in 2008, and most code in notmuch already calls strchr(3).
This fixes a compilation error on Android whose libc does not have
index(3).
The tar content `git archive` creates (reproducibly) have owner and
group set to 'root'. (GNU) tar writes user ids to the added file
`version` by default. The contents of tar archive looks better and
more consistent when owner and group in all files are the same.
While at it, split this long command line to multiple lines.
When configure could not get past initial compiler sanity check
the user was left with no explanation why this happened (usually
the reason is that compilers are not installed).
By printing the executed command line and re-executing it without
output redirection user gets better information how to proceed
(or ask for help) to resolve this problem.
The shell builtin 'printf' is used to print the executed command
line to ensure verbatim output.
These 210 messages are in several long threads, which is good for
testing our threading code, and may be useful just as a larger test
corpus in the future.
The non-field processor behaviour is is convert the corresponding
queries into a search for the unprefixed terms. This yields pretty
surprising results so I decided to generate a query that would match
the terms (i.e. none with that prefix) generated for an empty header.
At least Fedora and Debian now use
/usr/share/bash-completion/completions now. Apparently
/etc/bash_completion.d will be phased out at some point in the future.
Make test-lib-common.sh load test-lib-<$PLATFORM>.sh to create
additional shim for platform specifics.
Use test-lib-FREEBSD.sh to call GNU utilities instead of native ones.
- amended by db following Tomi's suggestions
The argument is that if the string passed to the field processor has
no spaces, then the added quotes won't have any benefit except for
disabling wildcards. But disabling wildcards doesn't seem very useful
in the normal Xapian query parser, since they're stripped before
generating terms anyway. It does mean that the query 'from:"foo*"' will
not be precisely equivalent to 'from:foo' as it is for the non
field-processor version.
This was broken by the addition of regexp searching. The detection of
wildcards is not currently done in the recursive call to parse_query,
because of quoting issues.
This function was deprecated in notmuch 0.21. We re-use the name for
a status returning version, and deprecate the _st name. One or two
remaining uses of the (removed) non-status returning version fixed at
the same time
This function was deprecated in notmuch 0.21. We finally remove the
deprecated API, and rename the status returning version to the simpler
name. The status returning is kept as a deprecated alias.

(cherry picked from commit 06adc27668)
Apparently some systems (MacOS?) have a system library called libutil
and the name conflict causes problems. Since this library is quite
notmuch specific, rename it to something less generic.
