The notmuch2 CFFI-based Python interface is not buildable unless
python3 dev package and python3 setuptools are installed.
Check that these exist in configure (and disable notmuch2 bindings
build if not) so that build of these bindings don't fail when make(1)
is executed.
This is a simple hack to enable out-of-tree builds, a concern raised
by Tomi in id:m24kzjib9a.fsf@guru.guru-group.fi
This change at least enables "make check" to complete without error,
but I'm sure it could be improved. I am not expert enough in
setuptools to know how.

When checking cryptographic signatures, Notmuch relies on GMime to
tell it whether the certificate that signs a message has a valid User
ID or not.
If the User ID is not valid, then notmuch does not report the signer's
User ID to the user. This means that the consumer of notmuch's
cryptographic summary of a message (or of its protected headers) can
be confident in relaying the reported identity to the user.
However, some versions of GMime before 3.2.7 cannot report Certificate
validity for X.509 certificates. This is resolved upstream in GMime
at https://github.com/jstedfast/gmime/pull/90.
We adapt to this by marking tests of reported User IDs for
S/MIME-signed messages as known-broken if GMime is older than 3.2.7
and has not been patched.
If GMime >= 3.2.7 and certificate validity still doesn't work for
X.509 certs, then there has likely been a regression in GMime and we
should fail early, during ./configure.
To break out these specific User ID checks from other checks, i had to
split some tests into two parts, and reuse $output across the two
subtests.

Xapian 1.4 is over 3 years old now (1.4.0 released 2016-06-24),
and 1.2 has been deprecated in Notmuch version 0.27 (2018-06-13).
Xapian 1.4 supports compaction, field processors and retry locking;
conditionals checking compaction and field processors were removed
but user may want to disable retry locking at configure time so it
is kept.
In case zlib not found by pkg-config(1) the pkg-config information
is resolved by attempting to print ZLIB_VERSION from from zlib
installation if it exists anyway.
If above done successfully compat/zlib.pc is written for forthcoming
pkg-config execution.
Since `set -u` is in effect (since 124a67e96, 2016-05-06),
expanding unset $PKG_CONFIG_PATH (would have) failed whenever tried.
Now it is changed to set as "$PKG_CONFIG_PATH:compat" if PKG_CONFIG_PATH
is set and is non-empty string, plain "compat" otherwise.
Zsh searches in the $fpath array for completion functions. By default
this includes $(prefix)/share/zsh/site-functions but not the existing
value. The prefix for zsh and notmuch isn't guaranteed to be the same
but it normally will be making this a better default for
zsh_completion_dir.
The entire python-cffi test suite is considered as a single test at
the level of the notmuch test suite. This might or might not be ideal,
but it gets them run.
Whitespace in $NOTMUCH_SRCDIR (and $PWD) may work in builds,
but definitely will not work in tests. It would be difficult
to make tests support whitespace in test filename paths -- and
fragile to maintain if done.
So it is just easier and safer to disallow whitespace there.
In case of out of tree build $NOTMUCH_SRCDIR differs from $PWD
(current directory). Extend this whitespace, and also previously
made unsafe characters check to $PWD too.
While check for GMime session key extraction support... was made
out of tree build compatible, related (and some unrelated) unsafe
characters are now checked in notmuch source directory path.
The known unsafe characters in NOTMUCH_SRCDIR are:
- Single quote (') -- NOTMUCH_SRCDIR='${NOTMUCH_SRCDIR}'
is written to sh.config in configure line 1328.
- Double quote (") -- configure line 521 *now* writes "$srcdir"
into generated c source file ($NOTMUCH_SRCDIR includes $srcdir).
- Backslash (\) could also be problematic in configure line 521.
- The added $ and ` are potentially unsafe -- inside double quotes
in shell script those have special meaning.
Other characters don't expand inside double quoted strings.
The extra flexibility of having both HAVE_EMACS (for yes, there is an
emacs we can use) and WITH_EMACS (the user wants emacs support) lead
to confusion and bugs. We now just force WITH_EMACS to 0 if no
suitable emacs is detected.
When using a promiscuous linker, _check_session_keys was working fine.
But some OSes (including some versions of Ubuntu) have set their
linker to always link in "--as-needed" mode, which means that the
order of the objects linked is relevant. If a library is loaded
before it is needed, that library will no longer be linked in the
final outcome. _check_session_keys.c was failing on those systems.

We never want ./configure to try to do something with an unassigned
variable. So, make the directory $TEMP_GPG at the start of the
testing of session-key handling, and clean it up afterwards as long as
the directory exists.

There are a few changes bundled here:
* say "No." explicitly if there's a failure.
* try to avoid implying that gpgme-config is necessary to build
notmuch itself (it's not, though it may be useful if you need to
rebuild gmime).
* leave _check_session_keys and _check_session_keys.c around if
./configure fails, so that the user can play with it more easily
for debugging.
* let error messages show when _check_session_keys.c is built.

Amended by DB: use command -v instead of which.
GMime 3.0 and higher can extract session keys, but it will *not*
extract session keys if it was built with --disable-crypto, or if it
was built against GPGME version < 1.8.0.
Notmuch currently expects to be able to extract session keys, and
tests will fail if it is not possible, so we ensure that this is the
case during ./configure time.
Part of this feels awkward because notmuch doesn't directly depend on
gpg at all. Rather, it depends on GMime, and the current
implementation of GMime depends on GPGME for its crypto, and GPGME in
turn depends on gpg.
So the use of gpg in ./configure isn't actually introducing a new
dependency, though if a future version of GMime were ever to move away
from GnuPG, we might need to reconsider.
Note that this changeset depends on
id:20190506174327.13457-1-dkg@fifthhorseman.net , which supplies the
rfc822 message test/corpora/crypto/basic-encrypted.eml used in it.

GMime 3.0 is over 2 years old now, and 2.6 has been deprecated in

If e.g. /lib is a link to /usr/lib, then the latter may not show up in
the way we expect in the output of ldconfig. 'test foo -ef bar' checks
if foo and bar have the same device and inode numbers. Since (at least
in bash, dash, ksh, and zsh) the shell dereferences symlinks before
applying the test, this includes both the case where file1 is equal to
file2 and the case where one is a symlink to the other.
This way, one can build for a different Ruby than $PATH/ruby
(e. g. different versions, or Ruby in other paths).

Correct URLs that have crept into the notmuch codebase with http://
when https:// is possible.
As part of this conversion, this changeset also indicates the current
preferred upstream URLs for both gmime and sup. the new URLs are
https-enabled, the old ones are not.
This also fixes T310-emacs.sh, thanks to Bremner for catching it.
When i'm trying to understand a message signature, i care that i know
who it came from (the "validity" of the identity associated with the
key), *not* whether i'm willing to accept the keyholder's other
identity assertions (the "trust" associated with the certificate).
We've been reporting User ID information based on the "trust"
associated with the certificate, because GMime didn't clearly expose
the validity of the User IDs.
This change relies on fixes made in GMime 3.0.3 and later which
include https://github.com/jstedfast/gmime/pull/18.
"notmuch help" doesn't mention "notmuch-emacs-mua" even though we
support it through the try_external_command() mechanism.
In addition, "notmuch help emacs-mua" doesn't work, even though we
ship the appropriate manpage.
This changeset fixes both of these problems.
python2 is going to be deprecated, and python3-sphinx is available all
the way back to oldoldstable. let's use the more modern version.
To make this work and still ship the manpages, tell ./configure to
prefer python3 over python, if it exists.
This flag should make it easier to write the code for session-key
handling.
Note that this only works for GMime 2.6.21 and later (the session key
interface wasn't available before then). It should be fine to build
the rest of notmuch if this functionality isn't available.
Note that this also adds the "session_key" built_with() aspect to
libnotmuch.
The advantage of having a target as opposed to running cppcheck by
hand
- reuse list of source files
- output errors in a format parsable, e.g. by emacs
- returns exit code 1 on any error, for possibly use in other
targets.
For the moment, leave this as an optional target. If desired, it can
be added to e.g. the release targets in the same way as the test
target.
Using two levels of directory for the stamps is arguably
overengineering, but it doesn't really cost anything, and leaves open
the possibility of putting other kinds of stamp files there.
This only checks "new" source files (w.r.t. their last check). A future target
(cppcheck-all ?) could blow away the stamp files first.
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.
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
In addition to use ${srcdir} and deliver ${NOTMUCH_SRCDIR} where needed,
source from ruby bindings had to be copied to the out-of-tree target
directory -- if the source files in source directory were referenced
in build and there were also built object files there, those could have
been considered as target files (and then not found when attempting
to create bindings/ruby/notmuch.so).
The ${srcdir} -- usually relative path to notmuch source -- works fine
in current ./configure and all makefiles. To have simple access to
notmuch source in tests and out of tree builds holding absolute path to
the source directory is useful.
When pkg-config does not find configure, a compat version of the
zlib.pc is created. In creation of that configure attempted to
read values of $zlib_cflags and $zlib_ldflags. In the usual case
those were undefined, and with `set -a` now in the beginning of
configure, configure broke.
Even if $zlib_cflags and $zlib_ldflags had values which were used
to create zlib.pc, the values were overwritten (with static content)
a few lines later in next pkg-config --cflags and --libs run. These
values would not be different and probably useless -- the following
boild would probably fail.
But instead of using those, CPATH and LIBRARY_PATH environment
variables can be used successfully (both while configuring and
building).
