Solaris support - missing or incompatible functions (v2)

Solaris support - missing or incompatible functions (v2)

[Vladimir.Marek]

Hi,

I'm re-sending the patches which were rebased to current top of the tree. Apart
from rebasing there has been no change made. I am using this notmuch for half a
year and it seems to work fine.

As I said in my previous email, not all the tests pass, but I know that the
failures in the testing itself and not in the code.

Notmuch test suite complete.
548/557 tests passed.
9 tests failed.

1 test fails because there are new exported symbols in notmuch binary
2 test fails because I don't have gpg
6 test fails because my emacs somehow refuses to send email


Thank you

[PATCH 1/4] getpwuid: check for standards compliance (Solaris support)

[Vladimir.Marek]

From: Blake Jones <blakej@foo.net>

Add checks to "configure" to see whether _POSIX_PTHREAD_SEMANTICS needs
to be defined to get the right number of arguments in the prototypes for
getpwuid_r().  Solaris' default implementation conforms to POSIX.1c
Draft 6, rather than the final POSIX.1c spec.  The standards-compliant
version can be used by defining _POSIX_PTHREAD_SEMANTICS.

This change also adds the file "compat/check_getpwuid.c", which
configure uses to perform its check, and modifies compat/compat.h to
define _POSIX_PTHREAD_SEMANTICS if configure detected it was needed.

[PATCH 3/4] strsep: check for availability (Solaris support)

[Vladimir.Marek]

From: Blake Jones <blakej@foo.net>

Solaris does not ship a version of the strsep() function.  This change
adds a check to "configure" to see whether notmuch needs to provide its
own implementation, and if so, it uses the new version in
"compat/strsep.c" (which was copied from Mutt, and apparently before
that from glibc).

[PATCH 4/4] timegm: add portable implementation (Solaris support)

[Vladimir.Marek]

From: Blake Jones <blakej@foo.net>

The timegm(3) function is a non-standard extension to libc which is
available in GNU libc and on some BSDs.  Although SunOS had this
function in its libc, Solaris (unfortunately) removed it.  This patch
implements a very simple version of timegm() which is good enough for
parse-time-string.c.

Hi Vladimir, Blake and everyone else.

This patch set looks good to me and tests (in Linux) pass. 

From code point of view these patches are IMO pushable.

There is just a small (but not so minor) thing missing;

The timegm(.c) implementation lacks copyright & licensing
information -- all the other compat files that are compiled
into executable does have this information so it is best
to keep this component also in line with those.

If you (either of you) can send new patch 4/4 as a reply to
this message it can be tracked along the first 3 in nmbug (*)

[PATCH 4/4] timegm: add portable implementation (Solaris support)

[Vladimir.Marek]

From: Blake Jones <blakej@foo.net>

The timegm(3) function is a non-standard extension to libc which is
available in GNU libc and on some BSDs.  Although SunOS had this
function in its libc, Solaris (unfortunately) removed it.  This patch
implements a very simple version of timegm() which is good enough for
parse-time-string.c.

Thanks Blake for your quick answer to my (perhaps too quick) question.

The copyright header gives FSF "owner"ship to the file -- which would be fine
by the project -- but does assigning copyright to the FSF work like this...
... I started to look around and found (among other pages) this:

http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=doc/Copyright/conditions.text;h=6e19adf0233900c9169e10fe7e0aa8d1feb73996;hb=HEAD

Maybe for liability reasons FSF needs more than just stating the copyright
at the beginning of file... I don't know -- but if this is the case maybe
the easiest thing is to remove (amend) the Copyright line out of the file.

In getline.c, and getdelim.c the code is taken from glibc. What I've 
understood this timegm.c is new art ?

IMHO this uncertainty is the last thing preventing putting this series
to the nmbug ready (to be pushed) queue...

I don't really care what sort of copyright it has.  Vladimir is the one
with the up-to-date tree at this point, so he would be best positioned
to update the text with whatever works best for the rest of notmuch.

To the best of my recollection, yes, I implemented this version of
timegm() from scratch, based on my understanding of what it needed to
do.

[PATCH 4/4] timegm: add portable implementation (Solaris support)

[Vladimir.Marek]

From: Blake Jones <blakej@foo.net>

The timegm(3) function is a non-standard extension to libc which is
available in GNU libc and on some BSDs.  Although SunOS had this
function in its libc, Solaris (unfortunately) removed it.  This patch
implements a very simple version of timegm() which is good enough for
parse-time-string.c.

Solaris support - missing or incompatible functions

[Vladimir.Marek]

Hi,

This is next series of patches adding Solaris support to notmuch. I am mostly
using what Blake Jones sent some time ago + I fixed all the comments he
received back then. Since it's mostly his work, it's IMO fair to keep
him as an author. But since I made sure the patches work, I'm signing
them. I'm really git newbie, so hopefully this is right thing to do ...

I tested the build on Solaris using Oracle Studio and on Linux using
gcc (to make sure I haven't break anything).

I can't run the notmuch 'make test' on Solaris (too old bash) and on linux the
results are

421/525 tests passed.
25 tests failed.
79 tests skipped.

but they are the same without my changes too ...

Cheers

[PATCH 1/4] getpwuid: check for standards compliance (Solaris support)

[Vladimir.Marek]

From: Blake Jones <blakej@foo.net>

Add checks to "configure" to see whether _POSIX_PTHREAD_SEMANTICS needs
to be defined to get the right number of arguments in the prototypes for
getpwuid_r().  Solaris' default implementation conforms to POSIX.1c
Draft 6, rather than the final POSIX.1c spec.  The standards-compliant
version can be used by defining _POSIX_PTHREAD_SEMANTICS.

This change also adds the file "compat/check_getpwuid.c", which
configure uses to perform its check, and modifies compat/compat.h to
define _POSIX_PTHREAD_SEMANTICS if configure detected it was needed.
