search for: haystack

Hello, I am trying to rebuild an index of 2+ million documents and have not been successful. I am running Python 2.7 Django 1.7 Haystack 2.1.1 Xapian 1.2.21 The index rebuild command I’m using is: django-admin.py rebuild_index --noinput --batch-size=100000 The rebuild completes but an immediate xapian-check returns this error: xapian-check ./archive_index record: baseB blocksize=8K items=2219301 lastblock=126957 revision=223 level...

Hi Olly, Thanks for the detailed response. I hadn’t realized there was a new xapian haystack backend. I’m going to try that but I have some upgrades to do first. Django 1.8, etc. Thanks, Ryan > On Feb 28, 2017, at 3:40 PM, Olly Betts <olly at survex.com> wrote: > > On Mon, Feb 27, 2017 at 10:29:46AM -0800, Ryan Cross wrote: >> I am trying to rebuild an index of 2...

Hi Olly, After upgrades my stack is now: Python 2.7 Django 1.8 Haystack 2.6.0 Xapian 1.4.3. (latest xapian haystack backend with some modifications) Using the same rebuild command as below but with —batch-size=50000 The issue has now become one of performance. I am indexing 2.2 million documents. Using delve I can see that performance starts off at about 100,000 re...

Hi, I'm the current developer of Xapian-Haystack, and I'm glad to announce that we've been finally able to install and pass all the tests of Xapian-Haystack with Xapian 1.3.3 in both Python 2 and 3, which means that Xapian-Haystack now supports Python 3. This naturally would not be possible without your efforts to push Xapian bindings to...

Hello folks- I have an issue with my Xapian index, and I am hoping someone can help me out with some ideas. I am running Xapian on Debian Squeeze as part of an openPLM installation. It is a django application that uses Postgresql as the database, and Haystack as the search engine. A couple of weeks ago, I misconfigured a crontab, and it made a recursive backup that filled up the hard drive on my server. I've got it cleaned out now, but I nothing I try to clear the index is working- I keep getting the error "DatabaseCorruptError: Cannot ope...

I have tested compiling vmkit using gcc3.4 and gcc4.4 Some vmkit files required that I added some explicit typecasts and #includes in order to compile. I have attached my changes against the vmkit svn trunk rev 69439 Using this patch both versions of gcc managed to compiled vmkit on my machine.

The above function can be seen as a "generalisation" of the "which" function as well as the function described in the following post: https://coolbutuseless.github.io/2018/04/03/finding-a-length-n-needle-in-a-haystack/ Would be possible to add such a function to base R? I am happy to work with someone from the R core team (if you wish) and suggest an implementation in C. Thank you Best regards, Morgan [[alternative HTML version deleted]]

FYI. I just had all of the squirrelmail prefs for all the users on one of my servers disappear. I have never had anything like this happen ever before. I'm in the process of finding the needle in the haystack of logs to try to get a handle on this. I'm sending this to the list as a heads up. Seems like Squirrelmail is not doing so good here over the last few months. John Hinton

Currently running with cranked up logging levels looking for a needle in a haystack. Anyone run into this? Douglas Sterner

We have a bad bug in udev if compiled with klibc. I seems that the needle string can't have a strlen of 1. This test case illustrates it: #include <stdio.h> #include <string.h> int main(int argc, char *argv[], char *envp[]) { char *hay = "a/b"; char *needle = "/"; if (memmem(hay, strlen(hay), needle, strlen(needle)) == NULL) printf("This uses the

Definitely agree with that. Our project coding standards require _zero_ warnings at commit time (but that only applies to our code, not imported libraries). > I've committed fixes to lots of -Wuninitialized warnings in my tree. > It's all just initializing loca...

You can also try running "dwarfdump --verify" on your dsymutil file (not on the dSYM bundle, but on the file inside the bundle). It sometimes gives a bit more information. Also simply using "dwarfdump - a" can...

Hi Folks, I've been digging for the solution to this for several hours now. If there is a solution, it must be one of the worst "needle-in-a-haystack" examples in R documentation! Essentially, I want to make an x-y plot in which the X-axis really is the X-axis (i.e. its vertical position is at y=0), and the Y-axis really is the Y-axis (i.e. its horizontal position is at x=0). Discussion, with toy examples, below. I have sort-of solved thi...
