This function uses GetSystemDirectory() to make sure we load the version
of the library from c:\windows\system32 (or local equivalent) rather than
whatever version lives in the cwd.
Do not double-report signatures from unrecognized authorities both as
"from unknown authority" and "not present". Fixes bug 1956, bugfix on
0.2.2.16-alpha.
Our attempt to make compilation work on old versions of Windows
again while keeping wince compatibility broke the build for Win2k+.
helix reports this patch fixes the issue for WinXP. Bugfix on
0.2.2.15-alpha; related to bug 1797.
Karsten says: "the ChangeLog should say it's a bugfix on
0.2.2.15-alpha, because enabling stats while Tor is running (which
leads to this false log message) is only possible since then."
Sounds right enough to me. Tell me if I'm wrong.
When the CellStatistics option is off, we don't store cell insertion
times. Doing so would also not be very smart, because there seem to
still be some performance issues with this type of statistics. Nothing
harmful happens when we don't have insertion times, so we don't need to
alarm the user.
Previously[*], the function would start with the first stream on the
circuit, and let it package as many cells as it wanted before
proceeding to the next stream in turn. If a circuit had many live
streams that all wanted to package data, the oldest would get
preference, and the newest would get ignored.
Now, we figure out how many cells we're willing to send per stream,
and try to allocate them fairly.
Roger diagnosed this in the comments for bug 1298.
[*] This bug has existed since before the first-ever public release
of Tor. It was added by r152 of Tor on 26 Jan 2003, which was
the first commit to implement streams (then called "topics").
This is not the oldest bug to be fixed in 0.2.2.x: that honor
goes to the windowing bug in r54, which got fixed in e50b7768 by
Roger with diagnosis by Karsten. This is, however, the most
long-lived bug to be fixed in 0.2.2.x: the r54 bug was fixed
2580 days after it was introduced, whereas I am writing this
commit message 2787 days after r152.
I'm going to use this to implement more fairness in
circuit_resume_edge_reading_helper in an attempt to fix bug 1298.
(Updated with fixes from arma and Sebastian)
An authority should never download a consensus if it has a live one,
but when it doesn't, it should admit that it's not going to get one,
and see if anybody else can give it one.
Fixes 1300, fix on 0.2.0.9-alpha
When we introduced the code to close non-open OR connections after
KeepalivePeriod had passed, we replaced some code that said
if (!connection_is_open(conn)) {
/* let it keep handshaking forever */
} else if (do other tests here) {
...
with new code that said
if (!connection_is_open(conn) && past_keepalive) {
/* let it keep handshaking forever */
} else if (do other tests here) {
...
This was a mistake, since it made all the other tests start applying
to non-open connections, thus causing bug 1840, where non-open
connections get closed way early.
Fixes bug 1840. Bugfix on 0.2.1.26 (commit 67b38d50).
