........
r1657 | phk | 2007-07-05 23:08:15 +0200 (Thu, 05 Jul 2007) | 2 lines
Clean up FlexeLint fluff.
........
r1658 | phk | 2007-07-06 12:07:30 +0200 (Fri, 06 Jul 2007) | 3 lines
Don't rewrite pipe'ed requests to "GET".
........
r1659 | phk | 2007-07-09 22:23:41 +0200 (Mon, 09 Jul 2007) | 10 lines
Make all protocol header fields writable, except obj.status and resp.status
(which are numeric, they'll follow shortly)
Unify the shmemlog tag used for failure to rewrite something, the Rx/Tx/Obj
distinction is not helpful enough to warrant the complexity of it.
........
r1660 | phk | 2007-07-09 22:34:59 +0200 (Mon, 09 Jul 2007) | 2 lines
Allow assignment to INT type variables
........
r1661 | phk | 2007-07-09 22:35:20 +0200 (Mon, 09 Jul 2007) | 2 lines
Allow assignment to obj.status and resp.status
........
r1662 | phk | 2007-07-10 21:46:16 +0200 (Tue, 10 Jul 2007) | 6 lines
Move string stuff to vcc_string.c, there's going to be a fair bit of it.
Give vcc_StringVal() a return value to say if it did anything so we can
emit better error messages when confused.
........
r1663 | phk | 2007-07-10 21:59:39 +0200 (Tue, 10 Jul 2007) | 5 lines
Add conversion from IP to string format to allow things like:
set bereq.http.HeyYou = client.ip " asked for " req.url;
........
r1664 | phk | 2007-07-10 22:07:07 +0200 (Tue, 10 Jul 2007) | 3 lines
Properly emit the header name in VRT_SetHdr();
........
r1665 | phk | 2007-07-10 22:08:39 +0200 (Tue, 10 Jul 2007) | 2 lines
Fix VRT_SetHdr() prototype
........
r1666 | phk | 2007-07-10 22:43:24 +0200 (Tue, 10 Jul 2007) | 2 lines
Add compiler side support for regsub() but only a dummy function in VRT.
........
r1667 | phk | 2007-07-10 23:30:47 +0200 (Tue, 10 Jul 2007) | 60 lines
Add "regsub" support for string manipulation.
Notice this facility is subject to change!
"regsub" is short for regular expression substitution and it is probably
easiest to explain with some examples:
sub vcl_recv {
set req.url = regsub(req.url, "#.*", "");
}
This will replace the requests URL with the output of the regsub() function
regsub() takes three arguments: the string to be examined, a regular
expression and a replacement string.
In this case, everything after the first '#' is removed (replaced
with nothing).
The replacement string recognizes the following magic sequences:
& - insert everything matched by the regexp
$0 - ditto.
$1 - replace with the first submatch of the regexp
$2 - replace with the second submatch of the regexp
...
$9 - replace with the ninth submatch of the regexp
(The $0..$9 syntax was chosen over the \0...\9 syntax in order to avoid
a nightmare of escape characters in the VCL source code. Arguments and
suggestions are welcome).
A more advanced example:
set bereq.http.ClientIP = regsub(client.ip, "(.*):(.*)", "$2 $1");
The client.ip variable expands to IP:port number, for instance
127.0.0.1:54662
The regular expression "(.*):(.*)" results in the the following matches:
& + $0 "127.0.0.1:54662"
$1 "127.0.0.1"
$2 "54662"
So the replacement string "$2 $1" results in "54662 127.0.0.1"
And the completed header which is sent to the backend will look like:
"ClientIP: 54662 127.0.0.1"
An even more advanced example would be:
set bereq.http.magic = "Client IP = " regsub(client.ip, ":", " port = ");
Where we also exploint the string concatenation ability of the "set" statement.
The result string is built in the request workspace, so you may need
to increase the workspace size if you do a lot of regsub()'s.
Currently there is no decent error handling for running out of workspace.
........
r1668 | phk | 2007-07-12 11:04:54 +0200 (Thu, 12 Jul 2007) | 6 lines
Add TIM_mono() and TIM_real() which return double representations of
timestamps on a monotonic and the UTC timescales respectively.
Doubles are much more convenient than timespecs for comparisons etc.
........
r1669 | phk | 2007-07-12 11:25:07 +0200 (Thu, 12 Jul 2007) | 2 lines
Replace ev_now() with TIM_mono().
........
r1670 | phk | 2007-07-12 11:25:45 +0200 (Thu, 12 Jul 2007) | 2 lines
Replace Uptime() with TIM_mono()
........
r1671 | phk | 2007-07-12 11:49:26 +0200 (Thu, 12 Jul 2007) | 6 lines
Change all timekeeping to use doubles instead of time_t and struct timespec.
Eliminate all direct calls to time(2) and clockgettime(2) and use TIM_real()
and TIM_mono() exclusively.
........
r1672 | phk | 2007-07-12 12:00:13 +0200 (Thu, 12 Jul 2007) | 2 lines

Added a new cli option, status, for checking the status of the varnish child process. This is for use in the webmin plugin.

r1683 | phk | 2007-07-13 09:21:46 +0200 (Fri, 13 Jul 2007) | 4 lines
Unify the recycle functionality of the acceptors, all three used the same
method.
........
r1684 | phk | 2007-07-13 09:27:50 +0200 (Fri, 13 Jul 2007) | 2 lines
Clean all but t_open timestamps to NAN at end of transaction.
........
r1685 | phk | 2007-07-13 09:47:45 +0200 (Fri, 13 Jul 2007) | 9 lines
Rename the "idle" field of struct worker to "used", which is more precise.
Don't use the "used" field to signal suicide for worker threads,
use the "wrq" field which is much more natural.
Set the "used" field to NAN before doing anything and assert that
somebody updated during the task.
