annotate src/filter.h @ 223:ffb1848a39db noffle
[svn] * src/util.c: Improve (correct) error detection when updating
timestamp file.
* src/content.h, src/content.c: Return Boolean success/fail from
Cont_write. Also ensure cont.first isn't polluted in the event
of a failed update.
* src/client.c,src/control.c,src/fetch.c,src/noffle.c,src/post.c,
src/pseudo.c: If Cont_write fails, don't do actions that need it to
have worked. Typically, don't update first and last article numbers
in group database.
* src/server.c: If groupinfo.lastupdate is unreadable or corrupt,
spot this and report it and give an explicit error when processing
NNTP NEWGROUPS command.
