* Nuke uses of memcmp outside of unit testsNick Mathewson2012-12-13
| | | | | | | We want to be saying fast_mem{cmp,eq,neq} when we're doing a comparison that's allowed to exit early, or tor_mem{cmp,eq,neq} when we need a data-invariant timing. Direct use of memcmp tends to imply that we haven't thought about the issue.

This is a machine-generated patch. To make it, start by getting the list of reserved identifiers using: git ls-tree -r --name-only HEAD | grep '\.[ch]$' | \ xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \ cut -f 1 | sort| uniq You might need gnu ctags. Then pipe the output through this script: ============================== use strict; BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; } chomp; next if ( /^__attribute__/ or /^__func__/ or /^_FILE_OFFSET_BITS/ or /^_FORTIFY_SOURCE/ or /^_GNU_SOURCE/ or /^_WIN32/ or /^_DARWIN_UNLIMITED/ or /^_FILE_OFFSET_BITS/ or /^_LARGEFILE64_SOURCE/ or /^_LFS64_LARGEFILE/ or /^__cdecl/ or /^__attribute__/ or /^__func__/ or /^_WIN32_WINNT/); my $ident = $_; my $better = $ident; $better =~ s/^_//; $better = "${better}_"; print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n"; ============================== Then run the resulting script on all the files you want to change. (That is, all the C except that in src/ext.)

* Don't log about reloading the microdescriptor cache at startupRoger Dingledine2012-09-03

* fix whitespace and trivial typoRoger Dingledine2012-09-03

* Warn at parse time for routerstatus entry missing a microdesc consensusNick Mathewson2012-07-31
| | | | | | | | In 0.2.3.18-rc, we started warning on this case while building a list of missing microdescriptor digests. That turned out to spam the logs; instead let's warn at parse time. Partial fix for bug 6404.

| | | | | | | | Also, try to resolve some doxygen issues. First, define a magic "This is doxygen!" macro so that we take the correct branch in various #if/#else/#endifs in order to get the right documentation. Second, add in a few grouping @{ and @} entries in order to get some variables and fields to get grouped together.
* Abort writing cached-microdescs if a failed write has occurred.Nick Mathewson2012-05-24
| | | | Bug 2954; fix on 0.2.2.6-alpha.
* Allow 0.2.3.x clients to use 0.2.2.x bridges.Roger Dingledine2012-01-25
| | | | | | | | | | | | | | | | | | | | | | Previously the client would ask the bridge for microdescriptors, which are only supported in 0.2.3.x and later, and then fail to bootstrap when it didn't get the answers it wanted. Fixes bug 4013; bugfix on 0.2.3.2-alpha. The fix here is to revert to using normal descriptors if any of our bridges are known to not support microdescs. This is not ideal, a) because we'll start downloading a microdesc consensus as soon as we get a bridge descriptor, and that will waste time if we later get a bridge descriptor that tells us we don't like microdescriptors; and b) by changing our mind we're leaking to our other bridges that we have an old-version bridge. The alternate fix would have been to change we_use_microdescriptors_for_circuits() to ask if *any* of our bridges can support microdescriptors, and then change the directory logic that picks a bridge to only select from those that do. For people living in the future, where 0.2.2.x is obsolete, there won't be a difference. Note that in either of these potential fixes, we have risk of oscillation if our one funny-looking bridges goes away / comes back.

* Make FetchUselessDescriptors fetch all desc typesNick Mathewson2011-08-29
| | | | | | | | | | | | Previously, if you were set up to use microdescriptors, and you weren't a cache, you'd never fetch router descriptors (except for bridges). Now FetchUselessDescriptors causes descriptors and mirodescs to get cached. Also, FetchUselessDescriptors changes the behavior of "UseMicrodescriptors auto" to be off, since there's no point in saying "UseMicrodescriptors 1" when you have full descriptors too. Fix for bug 3851; bugfix on 0.2.3.1-alpha.
* Oops; _actually_ enable microdesc-by-default for clientsNick Mathewson2011-08-15

| * Track where microdescs are referenced to prevent free errsNick Mathewson2011-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On IRC, wanoskarnet notes that if we ever do microdesc_free() on a microdesc that's in the nodelist, we're in trouble. Also, we're in trouble if we free one that's still in the microdesc_cache map. This code adds a flag to microdesc_t to note where the microdesc is referenced from, and checks those flags from microdesc_free(). I don't believe we have any errors here now, but if we introduce some later, let's log and recover from them rather than introducing heisenbugs later on. Addresses bug 3153.

Because of our node logic, directory caches will never use microdescriptors when they have the right routerinfo available.

| | | | | | | | | | | | | | | | Previously we ensured that it would get called periodically by doing it from inside the code that added microdescriptors. That won't work though: it would interfere with our code that tried to read microdescs from disk initially. Instead, we should consider rebuilding the cache periodically, and on startup.

Now that we can clean it, we want to add a condition to rebuild it: that should happen whenever we have dropped enough microdescriptors that we could save a lot of space. No changes file, since 0.2.3 doesn't need one and 0.2.2 already has some changes files for the backport of the microdesc_clean_cahce() function.
