memcmp() is unfortunately not guaranteed to read forward byte-by-byte,
which means that the clever use as a strncmp() without the pointless
strlen()s is not permitted, and can actually misbehave with
SSE-optimized string functions.
so implement proper equals() and starts_with() functions. as a bonus,
the calls are less cryptic.
for some reason lost in history, the prime_deltas were actually wrong,
leading to using composite numbers.
the right sequence is available at http://oeis.org/A092131.
the global timezone variable is glibc-specific.
so use timegm() instead of mktime() for the conversion.
as that is specific to the BSDs and glibc, provide a fallback.
amends 62a6099.
the test suite actually relies on it. it would be possible to adjust it,
but there is not much reason to make paths relative to HOME (as we
support convenient tilde expansion). so use the least invasive approach,
which is simply the old behavior. adjust the documentation accordingly.
This reverts commit da5ce5d8f4.
this removes the pathological O(<number of sync records> * <number of
new messages>) case at the cost of being a bit more cpu-intensive (but
O(<number of all messages>)) for old messages.
unless an info message is explictly marked as a continuation, it must
terminate any pending line (typically the progress information) first.
debug output is not affected, as it is mutually exclusive with info
output, and no debug lines are left unterminated outside clear scopes.
- introduce sys_error() and use it instead of perror() and
error(strerror()) in all expected error conditions
- perror() is used only for "something's really wrong with the system"
kind of errors
- file names, etc. are quoted if they are not validated yet, so e.g. an
empty string becomes immediately obvious
- improve and unify language
- add missing newlines
as opposed to earlier threats, BerkDB was not entirely dropped; i
suppose the isync 0.7 -> 0.8 change had a reason, so i added an
alternative UID storage scheme.
note that BDB 4.0 is not sufficient, as the db->open function changed in
an incompatible way ...
i updated the debian packaging except for a changelog entry.
note that i removed the upgrade blurb, as upstream now has a smooth
upgrade path down to at least isync 0.4.
