Previously it would give a bad result for one day every 1024 days. +JH/28 Bug 2996: Fix a crash in the smtp transport. When finding that the + message being considered for delivery was already being handled by + another process, and having an SMTP connection already open, the function + to close it tried to use an uninitialized variable. This would afftect + high-volume sites more, especially when running mailing-list-style loads. + Pollution of logs was the major effect, as the other process delivered + the message. Found and partly investigated by Graeme Fowler. + +JH/29 Change format of the internal ID used for message identification. The old + version only supported 31 bits for a PID element; the new 64 (on systems + which can use Base-62 encoding, which is all currently supported ones + but not Darwin (MacOS) or Cygwin, which have case-insensitive filesystems + and must use Base-36). The new ID is 23 characters rather than 16, and is + visible in various places - notably logs, message headers, and spool file + names. Various of the ancillary utilities also have to know the format. + As well as the expanded PID portion, the sub-second part of the time + recorded in the ID is expanded to support finer precision. Theoretically + this permits a receive rate from a single comms channel of better than the + previous 2000/sec. + The major timestamp part of the ID is not changed; at 6 characters it is + usable until about year 3700. + Updating from previously releases is fully supported: old-format spool + files are still usable, and the utilities support both formats. New + message will use the new format. The one hints-DB file type which uses + message-IDs (the transport wait- DB) will be discarded if an old-format ID + is seen; new ones will be built with only new-format IDs. + Optionally, a utility can be used to convert spool files from old to new, + but this is only an efficiency measure not a requirement for operation + Downgrading from new to old requires running a provided utility, having + first stopped all operations. This will convert any spool files from new + back to old (losing time-precision and PID information) and remove any + wait- hints databases. + +JH/30 Bug 3006: Fix handling of JSON strings having embedded commas. Previously + we treated them as item separators when parsing for a list item, but they + need to be protected by the doublequotes. While there, add handling for + backslashes. + +JH/31 Bug 2998: Fix ${utf8clean:...} to disallow UTF-16 surrogate codepoints. + Found and fixed by Jasen Betts. No testcase for this as my usual text + editor insists on emitting only valid UTF-8. + +JH/32 Fix "tls_dhparam = none" under GnuTLS. At least with 3.7.9 this gave + a null-indirection SIGSEGV for the receive process. + Exim version 4.96 -----------------
