2011-06-30Remove a few PCRE remnants.Tony Finch

I have also de-CVSed the ABOUT files and cleaned up a few introductory comments.
2011-06-17doc/doc-txt/NewStuff: note the ratelimit changes.Tony Finch
2011-06-17Improved ratelimit ACL condition.Tony Finch
Replace /noupdate with simpler /readonly option. (/noupdate is supported for backwards compatibility but no longer documented.) Better checking of the compatibility between per_* options and the ACL in which the ratelimit condition appears. Better handling of the start of a burst of email and of very low-rate clients. The new /count= option generalizes the per_byte and per_rcpt options. The new /unique= option is a rather groovy use for a Bloom filter.
2011-06-07exiwhat: Ensure the SIGUSR1 signal handler is safe.Tony Finch
exiwhat sends a SIGUSR1 to all exim processes to make them write their status to the process log. This is all done in the signal handler, but the logging code makes a number of calls that are not signal safe. These can all cause crashes or recursive locking in libc. Firstly, obtaining and formatting the timestamp is not safe. Doing so is unnecessary since exiwhat strips off the timestamp. This change removes timestamps from the process log. Secondly, exim closes all the logs after writing the process log. Closing syslog is not signal safe, and isn't necessary. We now only close the process log after writing to it. Thirdly, exim may calculate the process_log_path inside the signal handler which involves some possibly-unsafe string handling code. This change calculates the path when reading the configuration. Fourthly, when exim creates the process log file it might have to call the unsafe directory_create() though this is unlikely in practice. After this change exim only calls log_create() in a subprocess which is safe - it sometimes needs to do so anyway, if it is running as root and needs to drop privileges. The new code has no process log handling in log.c which eliminates some awkward special cases. It uses very simple code to write to the file in the signal handler, so it is obviously safe by inspection.

2011-03-22Avoid segfault on ref:name specified as uid.Phil Pennock
If group not also specified, make this a fatal error. If group specified, we'll error out anyway unless the group can be resolved. Approach considered but not followed: fatal config error if built with ref:name where name is a number. fixes bug 1098
2011-03-22Mention dns_use_edns0Phil Pennock
2011-03-22Added dns_use_edns0 main option.Phil Pennock
Is int because need a "do not override default" option, but that stops us from using the bool expansion logic and so we need to explicitly set numbers. Should try to find a way around that.

2011-03-22Harmonised TLS library version reporting.Phil Pennock
Only show if debugging. Layout now matches that introduced for other libraries in 4.74 PP/03.
2011-03-22Make ldap_require_cert work (not segfault).Phil Pennock
The clang complaint, which also triggered a gcc complaint, was legitimate. My first test, which suggested no problem, was flawed. This: ldap_start_tls ldap_require_cert = demand would cause a segfault on LDAP lookup. fixes bug 230
2011-03-22Set "new since" to the 4.75 release.Phil Pennock
Stripped all .new/.wen except the exemplar. 4.75 was a stabilisation release, reset the accumulation of "this is new".

C89 compilers do not support variable argument macros. Our copy of valgrind.h now differs from upstream. Reported-by: Heiko Schlichting <heiko.schlichting@fu-berlin.de>

2011-02-05Strip \x{c2} from .txt files and audit.Phil Pennock
Am unable to keep the build process from inserting spurious \x{c2} characters into the created .txt files. Strip the characters in Tidytxt. Add SanityTestText to do a final audit for non-ASCII characters in the .txt files. Dependency: pcregrep if available, else uses Perl.
