Mercurial: Changelog

debugobsolete: add formatter support (issue5134) It appears that computing index isn't cheap if --rev is specified. That's why "index" field is available only if --index is specified. I've named marker.flags() as "flag" because "flags" implies a list or dict in template world. Thanks to Piotr Listkiewicz for the initial implementation of this patch.

formatter: add function to convert dict to appropriate format This will be used to process key-value pairs by formatter. The default field names and format are derived from the {extras} template keyword. Tests will be added later.

check-code: make dict() pattern less invasive 'foodict(x=y)' should be allowed.

hgweb: tweak zlib chunking behavior When doing streaming compression with zlib, zlib appears to emit chunks with data after ~20-30kb on average is available. In other words, most calls to compress() return an empty string. On the mozilla-unified repo, only 48,433 of 921,167 (5.26%) of calls to compress() returned data. In other words, we were sending hundreds of thousands of empty chunks via a generator where they touched who knows how many frames (my guess is millions). Filtering out the empty chunks from the generator cuts down on overhead. In addition, we were previously feeding 8kb chunks into zlib compression. Since this function tends to emit *compressed* data after 20-30kb is available, it would take several calls before data was produced. We increase the amount of data fed in at a time to 32kb. This reduces the number of calls to compress() from 921,167 to 115,146. It also reduces the number of output chunks from 48,433 to 31,377. This does increase the average output chunk size by a little. But I don't think this will matter in most scenarios. The combination of these 2 changes appears to shave ~6s CPU time or ~3% from a server serving the mozilla-unified repo.

test-gpg: run migration of v1 secret keys beforehand This suppresses unwanted output at "hg sign".

test-gpg: start gpg-agent under control of the test runner GnuPG v2 automatically starts gpg-agent. We should kill the daemon process.

test-gpg: make temporary copy of GNUPGHOME GnuPG v2 will convert v1 secret keys and create a socket under $GNUPGHOME. This patch makes sure no state would persist. We no longer need to verify trustdb.gpg, which was added by aae219a99a6e.
