I'm trying to test a trivial patch to set FD_CLOEXEC on the flintlock lockfd when using F_OFD_SETLK and am running into a build failure even in an unpatched state. This is on a Debian jessie amd64 system building the jessie-backports version. The stable version (1.2.19-1+deb8u1) works and builds fine using the same commands, however I also encountered a similar build problem in a sid chroot

In other words, is it possible to avoid duplicates if new documents are inserted into the DB by another process in-between ->get_mset calls when reusing Xapian::Enquire objects? I do some expensive processing on each mset window, so I always limit the results to limit heap usage even if I'm planning on going through a big chunk of the DB: $mset = $enq->get_mset(0, 1000);

The Database object itself effectively does (it works in a snapshot of the state of the database when you open it, or last called reopen() which

Hi, this is my first time using the nlme package, and I ran into the following puzzling problem. I estimated a mixed effects model using lme, once using groupedData, once explicitly stating the equations. I had the following outputs. All the coefficients were similar, but they're always slightly different, making me think that it's not due to numerical error. Also, what is the

Report by Eric Lindblad 30-09-2015 http://www.ericlindblad.blogspot.com The xapian-core-1.2.21 'ambiguous overload' error on the files /backends/brass/brass_check.cc and /backends/chert/chert_check.cc appear to be resultant of a bug reported in gcc-3.3.4, which was fixed for 3.4.2 [Sept. 6, 2004] and 3.5.

Hi, I'm a developer working on an application for Windows XP and have been using the Win32 API call FileLockEx() on shared files (writing or reading). This has been working fine, but we now have a customer where this causes the following error when trying to lock a file on a samba network drive (it works fine if the file is local or on a windows shared drive): LockFileEx returns false.

Hi, I have read the concurrency webpage from the Xapian documentation: http://getting-started-with-xapian.readthedocs.io/en/latest/concepts/concurrency.html But it is still not clear to me how to ensure thread-safety when using libxapian (C++ API). Usually when doing multi-threading many threads can read the same variable concurrently without locking provided none of the threads modifies the

Hi, I've a program which: 1. Sets XAPIAN_FLUSH_THRESHOLD=1000 2. Opens a (new) database for write 3. Indexes a few thousand documents 4.

Hello, I'm using samba 4.7.3 to run an AD and I'm currently having issues with the MIT kerberos because it stops some time after starting (and apparently working correctly) without logging nothing out of the ordinary. My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which we're migrating from) and the one I mentioned in CentOS 7 (which will be the only DC in the future).

The attached set of patches adds support for OS/2 using Watcom compiler (tested with Open Watcom 1.9). My only interest was building a working dll (the last patch in the set adds a makefile for it), therefore I did not touch other places: If there is interest, I can do so.

This commit will break OS/2's EMX 0.9d library (GCC 2.8.1) which has been been replaced by klibc. Considering the age of EMX and lack of testing and that klibc contains so many improvements I think this is exceptable. --- include/FLAC/ordinals.h | 17 +++++++++-------- src/flac/main.c | 2 +- src/libFLAC/metadata_iterators.c | 2 +-

I think I just saw a thread go by on " how do I make interactive PDF from rgl output" but I ignored it at the time and can't seem to find consensus result on google. Essentially I wanted to create pdf or other output to share a 3D plot and let viewers interact with it but it still wasn't clear on easiest way to do this. Is this 2009 page the best reference?
