We want to forbid this pattern since, unlike the other log_*()
macros, log_debug() conditionally evaluates its arguments only if
debug-level logging is enabled. Thus, a call to
log_debug("%d", x++);
will only increment x if debugging logs are enabled, which is
probably not what the programmer intended.
One bug caused by this pattern was #30628.
This script detects log_debug( ) calls with any of E++, E--, ++E,
or --E in their arguments, where E is an arbitrary expression.
Closes ticket 30743.
Fix levels for subsystems that depend on log/err
* winprocess (security) doesn't use err:
* call windows process security APIs as early as possible
* init err after winprocess
* move wallclock so it's still after err
* network and time depend on log:
* make sure that network and time can use logging.
* init network and time after log
Add comments explaining the module init order.
Fixes bug 31615; bugfix on 0.4.0.1-alpha.
tor-github/pr/1283, with the following changes:
* cherry-pick the merge commit in 1283 on top of...
* tor-github/pr/1174, but with the last commit re-worded to remove
the fixup, because fixups break our push rules.
This is an "ours" merge, except for the bugfix version change in
changes/bug30649.
When we parse a CLEAR line (e.g., "/OrPort" or /OrPort blah blah"),
we always suppress the value, even if one exists. That means that
the block of code was meant to handle CLEAR lines didn't actually do
anything, since we previously handled them the same way as with
other empty values.
Closes ticket 31529.
Some platforms (macOS, maybe others?) can swallow the last write before an
abort. This issue is probably caused by a race condition between write
buffer cache flushing, and process termination. So we write an extra
newline, to make sure that the message always gets through.
Fixes bug 31571; bugfix on 0.3.5.1-alpha.
