We do this in too many places throughout the code; it's time to start
clamping down.
Also, refactor Karsten's patch to use strchr-then-strndup, rather than
malloc-then-strlcpy-then-strchr-then-clear.
When we added support for fractional units (like 1.5 MB) I broke
support for giving units with no space (like 2MB). This patch should
fix that. It also adds a propoer tor_parse_double().
Fix for bug 1076. Bugfix on 0.2.2.1-alpha.
When determining how long directory requests take or how long cells spend
in queues, we were comparing timestamps on microsecond detail only to
convert results to second or millisecond detail later on. But on 32-bit
architectures this means that 2^31 microseconds only cover time
differences of up to 36 minutes. Instead, compare timestamps on
millisecond detail.
Now, when you call tor --digests, it dumps the SHA1 digest of each
source file that Tor was built with. We support both 'sha1sum' and
'openssl sha1'. If the user is building from a tarball and they
haven't edited anything, they don't need any program that calculates
SHA1. If they _have_ modified a file but they don't have a program to
calculate SHA1, we try to build so we do not output digests.
tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing. We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed. They were not actually useful for
telling the version of Tor files in the wild.
svn:r17867
Make generic address manipulation functions work better. Switch address policy code to use tor_addr_t, so it can handle IPv6. That is a good place to start.
svn:r16178
Another test for the increasingly bad check-spaces style checker to check: #else\n#if is almost a sure sign of a failure to use #elif. Fortunately, we only did that 3 times.
svn:r13039
Push the strdups used for parsing configuration lines into parse_line_from_string(). This will make it easier to parse more complex value formats, which in turn will help fix bug 557
svn:r13020
New, slightly esoteric function, tor_malloc_roundup(). While tor_malloc(x) allocates x bytes, tor_malloc_roundup(&x) allocates the same size of chunk it would use to store x bytes, and sets x to the usable size of that chunk.
svn:r12981
Improved skew reporting: "You are 365 days in the duture" is more useful than "You are 525600 minutes in the future". Also, when we get something that proves we are at least an hour in the past, tell the controller "CLOCK_SKEW MIN_SKEW=-3600" rather than just "CLOCK_SKEW"
svn:r12283
Refactor write_chunks_to_file_impl: break out the "pick a temporary name if it makes sense, and open the right filename" logic and the "close the file and unlink or rename if necessary" logic. This will let us write big files in a smarter way than "Build a big string" or "make a list of chunks", once we get around to using it.
svn:r11300
Glibc (and maybe others) define a mallinfo() that can be used to see how the platform malloc is acting inside. When we have it, dump its output on dumpmemusage().
svn:r10996
Another patch from croup: drop support for address masks that do not correspond to bit prefixes. Nobody has used this for a while, and we have given warnings for a long time.
svn:r10881
Patch from croup: rewrite the logic of get_next_token() to do the right thing with input that ends at weird places, or aligns with block boundaries after mmap. should fix bug 455. Needs fuzzing.
svn:r10847
Sun CC likes to give warnings for the do { } while(0) construction for making statement-like macros. Define STMT_BEGIN/STMT_END macros that do the right thing, and use them everywhere.
svn:r10645
First bare stubs of ipv6 work: commit some (untested, hence doublessly broken) implementations of inet_ntop/pton for systems that lack them.
svn:r10326
Add math functions to round values to the nearest power of 2. Make mempools more careful about making sure that the size of their chunks is a little less than a power of 2, not a little more.
svn:r10304
Partial backport candidate: do not rely on finding a \0 after an mmaped() router/extrainfo file. Also, set journal length correctly when starting up.
svn:r10248
Move all struct-offset-manipulation macros into util.h, and use them consistently. Because there are days when "SUBTYPE_P(handle, subtype, _base)" is just easier to read and write than "(basetp*)(((handle) - STRUCT_OFFSET(subtype, _base))".
svn:r9592
Handle errors on opening cached-routers* more uniformly and sanely: log not-found errors at level INFO, and all other errors at level WARN. Needs testing on win32.
svn:r9569
Add documentation to src/common/*.h; improve documentation for SMARTLIST_FOREACH; remove never-used options and corresponding tests from tor_strpartition.
svn:r9483
Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were. Oops. Hey, kids! Fixing some of these could be your first Tor patch!
svn:r9477
Add unit tests for tor_mmap_file(); make tor_mmap_t.size always be the size of the file (not the size of the mapping); add an extra argument to read_file_to_str() so it can return the size of the result string.
svn:r8762
Move is_local_IP to config.c; have it check for same-/24; make it used only for reachability (not for banwidth, because that is probably not what we want). Fixes an XXX.
svn:r8578
And another GCC change: predict that tor_frees() are usually real frees, and tor_asserts() usually wont happen. Other test should wait till -fprofile-arcs
svn:r7022
