Tarballs/zipballs are at http://apr.apache.org/dev/dist/. I
anticipate that we will release this, or its replacement if flawed, in
conjunction with the upcoming apr 1.4 release. Hopefully we will be
ready for T&R of that soon :)
+/-1
[+1] Release apr-util 1.3.10 as GA
Sorry for voting late, but I was on vacation :)
+1 although there are still two problems on Solaris 10 for test_reslist,
but not a regression.
I built and made check on the following platforms:
- Solaris 8 + 10, Sparc
- SuSE Linux Enterprise 10 32 and 64 Bit
- RedHat Enterprise Linux 5, 64 Bit
Using all combinations of:
apr 1.3.12 / 1.4.2
expat builtin / 2.0.1
dso disable / enable
Berkeley DB 4.8.30 5.0.26 5.1.19
sqlite 3.7.2
mysql 6.0.2 (only Solaris)
oracle 10.2.0.4.0 (only Solaris)
All builds suceeded, all make check ran fine, except for two cases on
Solaris 10 (this time not Niagara, but instead old sun4u - V240 with 2
CPUs).
I reran the tests and couldn't reproduce the problem, so it is not
deterministic. Out of 48 build combinations on Solaris 10, only three
had a problem. This is similar to 1.3.10, but it is not always the same
combinations. Like for 1.3.10 problem happens on Solaris 10 but not on
Solaris 8.
Details on Solaris 10 test failures
- only in testreslist
- two types of failures:
- twice crashes (segmentation fault)
- once non-terminating loop
- Crashes seem not really related to used apr version (one for 1.3 and
one for 1.4)
1) Segmentation Fault
