ref-manual: Applied Paul Eggleton's buildhistory patch 2 of 5.

Browse Source 
Additional information added to the end of the
"Build History Package Information" section."

Buildhistory now collects information on SRCREV values for recipes
fetched from a version control system e.g. Git; additionally a
buildhistory-collect-srcrevs tool is provided to gather this and
convert it to a format suitable for inclusion in global configuration.
Add information on these new features to the appropriate section.

Finally, for those recipes that are fetched from a version control
system (such as Git) there is a file that lists the source revision(s)
specified in the recipe and the actual revision used when building
(which may be different when <filename>SRCREV</filename> is set to
<filename>${AUTOREV}</filename> for example). Here is an example
of one of these files:
<filename>buildhistory/packages/emenlow-poky-linux/linux-yocto/latest_srcrev</filename>):
<literallayout class='monospaced'>
# SRCREV_machine = "b5c37fe6e24eec194bb29d22fdd55d73bcc709bf"
SRCREV_machine = "b5c37fe6e24eec194bb29d22fdd55d73bcc709bf"
# SRCREV_emgd = "caea08c988e0f41103bbe18eafca20348f95da02"
SRCREV_emgd = "caea08c988e0f41103bbe18eafca20348f95da02"
# SRCREV_meta = "c2ed0f16fdec628242a682897d5d86df4547cf24"
SRCREV_meta = "c2ed0f16fdec628242a682897d5d86df4547cf24"
</literallayout>
You can use the <filename>buildhistory-collect-srcrevs</filename>
command to collect the stored <filename>SRCREV</filename> values
from build history and report them in a format suitable for use in
global configuration (for example, local.conf or a distro include
file) to override floating AUTOREV values to a fixed set of revisions.
Here is some example output from this command:
<literallayout class='monospaced'>
# emenlow-poky-linux
SRCREV_machine_pn-linux-yocto = "b5c37fe6e24eec194bb29d22fdd55d73bcc709bf"
SRCREV_emgd_pn-linux-yocto = "caea08c988e0f41103bbe18eafca20348f95da02"
SRCREV_meta_pn-linux-yocto = "c2ed0f16fdec628242a682897d5d86df4547cf24"
# core2-poky-linux
SRCREV_pn-kmod = "62081c0f68905b22f375156d4532fd37fa5c8d33"
SRCREV_pn-blktrace = "d6918c8832793b4205ed3bfede78c2f915c23385"
SRCREV_pn-opkg = "649"

Some notes on using the <filename>buildhistory-collect-srcrevs</filename>
command:
<itemizedlist>
<listitem><para>By default only values where the SRCREV was
not hardcoded (usually when AUTOREV was used) are reported
- use the <filename>-a</filename> option to see all SRCREV
values.</para></listitem>
<listitem><para>The output statements may not have any effect
in the face of overrides applied elsewhere in the build system
configuration; use the <filename>-f</filename> option to add the
<filename>forcevariable</filename> override to each output line
if you need to work around this.</para></listitem>
<listitem><para>The script does not do any special handling for
building for multiple machines; however it does place a
comment before each set of values specifying which triplet
(for example <filename>emenlow-poky-linux</filename>) that they
belong to as shown above.</para></listitem>
</itemizedlist>
