in the chroot method, when the user account was deleted the /etc/group file was purged as well (or some similar timeline of events).

the result was that 'user' was not a member of www-data, tomcat6, users, staff, etc anymore. potential work-around committed in r8913. maybe it fixes it, maybe it don't.

still present after the fix in build8915

comment:3 Changed 7 years ago by hamish

rc.local fix didn't take. re-fixed in r8928.

even with the groups updated I still get an Internal Server Error when I go to the mapfish example listed in the quickstart.

same "FATAL: database "v2.2_mapfishsample" does not exist" error as reported earlier.

Hi,

Brian and myself have been working on this one a bit, and we have a theory about what's happening.

exec summary: the data base was not created correctly; it's not mapfish's fault. inchroot.sh is setting LC_ALL=C which is propagating to install_postgis.sh and the postgres templates are being created as SQL_ASCII encoding instead of UTF8 encoding. Mapfish was expecting it to be UTF8.

solutions include: not having inchroot do that, having install_postgis.sh unset/reset the LANG variables at the beginning of its script, and/or explicitly stating the encoding type at each createdb step on the liveDVD.

We'll wait to hear why inchroot was doing that before touching it, have added some debug messages to install_postgis.sh to get a clearer idea of what's happening there, and Brian's gone around and added "-E UTF8" in a number of places where it wasn't explicitly stated.


from yesterday's 6.0-build-r8942 build log:

...
*************** PICKED VERSIONS ****************
[versions]

*************** /PICKED VERSIONS ***************
createdb: database creation failed: ERROR:  new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)
HINT:  Use the same encoding as in the template database, or use template0 as template.
...

in the 5.5 release all postgres tables were encoded as UTF8, same for 6.0beta7 (the last of the remastersys line); we checked.

For yesterday's 6.0-build-r8942 however:

hopefully fixed by r8996. (unset LC_ALL in install_postgis.sh)
