* Apparently "mutex" is already claimed by a system header on Solaris.
* File locking on Linux (probably other operating systems) is pretty
dumb when lots of processes are trying to lock a single file
for serialisation: all of the processes are woken each time
that the file is unlocked. Most of the process will simply loop
inside the kernel and attempt to lock again. Presumably this
approach makes nonblocking locks and EINTR easier to do, but
it does mean that you can get occasional load average spikes.
Add MUTEX_SEMAPHORE to implement System V semaphore based lock,
which does not have this problem in Linux. Warning: System V
semaphores are a finite resource, and they are not released
automatically. See: prayer-sem-prune.
* Quotas now reported in MBytes rather than KBytes.
* Add download links for text/html and text/plain attachments
* Fix bug with body->type TYPEMESSAGE: c-client API very poorly
documented :(
* Strip out common HTML entity encodings that might be used in
HREFs with text/html attachments.
* Fix mydb_db3.c to work with DB4.
* Integrate into Tony's funky packaging system for Hermes and PPSW.
* Add interface to automatic spam folder pruning utility that I
wrote for Cyrus (controlled through special Sieve files).
* Fix uploads where mailboxes contain NUL characters (translate to
space?)
* Assorted minor bugfixes
* Fix nasty /redirect bug that I managed to introduce by switching
from url_encode to canon_encode to work around bug in Opera.
Missing a url_encode: infinite loop from dumb UAs :(. Otherwise
identical to 1.0.9.
* Few minor bug fixes, covered in CVS history.
pkgsrc changes:
* Rename the source rc.d script in the default RCD_SCRIPTS style.
* Respect ${VARBASE}.
* Avoid the DB_VERB_CHKPOINT flag with latest db4 (where it's been removed).
* Patch from jdc@ for 64-bit big-endian hosts.
XXX rc.d script doesn't stop all the prayer slaves
Creates user and group now.
"make reinstall" works again.
No change of ownership of /usr/pkg/sbin anymore.
New RCD script (needs work on non-NetBSD platforms regarding "ps" command
options).
Bump revision.
* Remove "Feel free to send more messages" text from vacation messages.
* Disable gzip for Opera attachment download.
* Fixed config->prayer_user expansion.
* fatal() shouldn't dump core if root.
* Fixed abook_list boundary condition when current entry is last on page.
* Added message download link for Message/RFC822 sections.
* Fix session_server() ping interval logic.
* Other bug-fixes
Prayer is a small and fast HTTP to IMAP gateway written entirely in C.
* Uses persistent connections to IMAP server and support servers.
* Target folders remain SELECTed: not a simple-minded proxy.
* Full caching (including sort/thread cache) for each open folder.
* Up to five persistent IMAP connections (typically one or two in use):
o INBOX and one other folder
o Postponed message folder stream
o Preferences stream
o Folder transfer stream
o Various optimisations/sharing to minimise actual IMAP connections
* Directory cache: single round trip to IMAP server for directory listing.
* Works well with UW IMAP server (even using Unix format mail folders).
* Little discernible load on a Pentium III class system running Linux with
5,000 logins/day (400 logins/hour, 150 concurrent logins)
* Uses 10% to 20% of the CPU and 400 MBytes of RAM on a PIII class system
with 23,000 logins/day (1,700 logins/hour, 850 concurrent logins peak)
* Aggressive HTTP/1.0 and 1.1 connection caching to reduce SSL overhead.
* Optional gzip compression of pages tunable by IP address range.
