[logging-log4cxx] branch LOGCXX-527 updated (91d914db -> b5db5f0a)
This is an automated email from the ASF dual-hosted git repository.
rmiddleton pushed a change to branch LOGCXX-527
in repository https://gitbox.apache.org/repos/asf/logging-log4cxx.git
discard 91d914db Merge branch 'master' into LOGCXX-527
discard 727196f1 add in macro to compile on windows
discard 54aff6f2 disable tests that won't work and make sure the create directory test works
discard 1cfbdba0 Ensure that test1 and test2 work by not appending to log files
discard 8377e423 Time based tests kinda work with fake clock at this point
discard ed867eef Print out failing sub-tests
new b5db5f0a LOGCXX-527: mock the clock for tests
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (91d914db)
\
N -- N -- N refs/heads/LOGCXX-527 (b5db5f0a)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 1 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.

[logging-log4cxx] 01/01: LOGCXX-527: mock the clock for tests
Posted by rm...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
rmiddleton pushed a commit to branch LOGCXX-527
in repository https://gitbox.apache.org/repos/asf/logging-log4cxx.git
commit b5db5f0ab56955b2b89c2ed2364c048a3514b9c3
Author: Robert Middleton <ro...@rm5248.com>
AuthorDate: Thu Mar 24 21:23:14 2022 -0400
LOGCXX-527: mock the clock for tests
Mock the clock for unit tests to make them more reliable and configurable.
This also cleans up some APR calls to make us less dependent on APR and
more on standard C++ features
