1 Changes in BitBake 1.8.x:
2 - Fix -f (force) in conjunction with -b
3 - Fix exit code for build failures in --continue mode
4 - Fix git branch tags fetching
5 - Change parseConfigurationFile so it works on real data, not a copy
6 - Handle 'base' inherit and all other INHERITs from parseConfigurationFile
8 - Fix getVarFlags bug in data_smart
9 - Optmise cache handling by more quickly detecting an invalid cache, only
10 saving the cache when its changed, moving the cache validity check into
11 the parsing loop and factoring some getVar calls outside a for loop
12 - Cooker: Remove a debug message from the parsing loop to lower overhead
13 - Convert build.py exec_task to use getVarFlags
14 - Update shell to use cooker.buildFile
15 - Add StampUpdate event
16 - Convert -b option to use taskdata/runqueue
17 - Remove digraph and switch to new stamp checking code. exec_task no longer
19 - Make fetcher timestamp updating non-fatal when permissions don't allow
21 - Add BB_SCHEDULER variable/option ("completion" or "speed") controlling
22 the way bitbake schedules tasks
23 - Add BB_STAMP_POLICY variable/option ("perfile" or "full") controlling
24 how extensively stamps are looked at for validity
25 - When handling build target failures make sure idepends are checked and
26 failed where needed. Fixes --continue mode crashes.
27 - Fix problems with recrdeptask handling where some idepends weren't handled
29 - Work around refs/HEAD issues with git over http (#3410)
30 - Add proxy support to the CVS fetcher (from Cyril Chemparathy)
31 - Improve runfetchcmd so errors are seen and various GIT variables are exported
32 - Add ability to fetchers to check URL validity without downloading
33 - Improve runtime PREFERRED_PROVIDERS warning message
34 - Add BB_STAMP_WHITELIST option which contains a list of stamps to ignore when
35 checking stamp dependencies and using a BB_STAMP_POLICY of "whitelist"
36 - No longer weight providers on the basis of a package being "already staged". This
37 leads to builds being non-deterministic.
38 - Flush stdout/stderr before forking to fix duplicate console output
39 - Make sure recrdeps tasks include all inter-task dependencies of a given fn
40 - Add bb.runqueue.check_stamp_fn() for use by packaged-staging
41 - Add PERSISTENT_DIR to store the PersistData in a persistent
42 directory != the cache dir.
43 - Add md5 and sha256 checksum generation functions to utils.py
44 - Make sure Build Completed events are generated even when tasks fail
45 - Correctly handle '-' characters in class names (#2958)
46 - Make sure expandKeys has been called on the data dictonary before running tasks
47 - Correctly add a task override in the form task-TASKNAME.
48 - Revert the '-' character fix in class names since it breaks things
49 - When a regexp fails to compile for PACKAGES_DYNAMIC, print a more useful error (#4444)
50 - Allow to checkout CVS by Date and Time. Just add HHmm to the SRCDATE.
51 - Move prunedir function to utils.py and add explode_dep_versions function
52 - Raise an exception if SRCREV == 'INVALID'
53 - Fix hg fetcher username/password handling and fix crash
54 - Fix PACKAGES_DYNAMIC handling of packages with '++' in the name
55 - Rename __depends to __base_depends after configuration parsing so we don't
56 recheck the validity of the config files time after time
57 - Add better environmental variable handling. By default it will now only pass certain
58 whitelisted variables into the data store. If BB_PRESERVE_ENV is set bitbake will use
59 all variable from the environment. If BB_ENV_WHITELIST is set, that whitelist will be
60 used instead of the internal bitbake one. Alternatively, BB_ENV_EXTRAWHITE can be used
61 to extend the internal whitelist.
63 Changes in BitBake 1.8.10:

84 - Use git-fetch instead of git-pull removing any need for merges when
85 fetching (we don't care about the index). Fixes fetch errors.
86 - Add BB_GENERATE_MIRROR_TARBALLS option, set to 0 to make git fetches
87 faster at the expense of not creating mirror tarballs.
