[bitbake-devel] Mercurial fetcher doesn't work for me (patch included)

[Peter Kjellerstedt]

For a link to a tool to be created in $(BUILDDIR)/tmp/hosttools, the tool should be added to either ${HOSTTOOLS} (for tools that must exist) or ${HOSTTOOLS_NONFATAL} (for tools that may exist). This is typically done in bitbake.conf (for tools that everyone needs) or conf/layer.conf (if the tool is required only when using that layer). hg belongs in ${HOSTTOOLS_NONFATAL}.

I'm trying to write a recipe for a local repo that is kept in mercurial, and encountering the following problem:

Traceback (most recent call last):
  File "/home/joel-cohen/code/waveos2/poky/bitbake/lib/bb/data_smart.py", line 808, in DataSmart.getVarFlag(var='PV', flag='_content', expand=True, noweakdefault=False, parsing=False, retparser=False):
             if expand or retparser:
    >            parser = self.expandWithRefs(value, cachename)
             if expand:
  File "/home/joel-cohen/code/waveos2/poky/bitbake/lib/bb/data_smart.py", line 416, in DataSmart.expandWithRefs(s='0.0.4+git${SRCPV}', varname='PV'):
                 try:
    >                s = __expand_var_regexp__.sub(varparse.var_sub, s)
                     try:
  File "/home/joel-cohen/code/waveos2/poky/bitbake/lib/bb/data_smart.py", line 108, in VariableParse.var_sub(match=<_sre.SRE_Match object; span=(9, 17), match='${SRCPV}'>):
                         raise Exception("variable %s references itself!" % self.varname)
    >            var = self.d.getVarFlag(key, "_content")
                 self.references.add(key)
  File "/home/joel-cohen/code/waveos2/poky/bitbake/lib/bb/data_smart.py", line 808, in DataSmart.getVarFlag(var='SRCPV', flag='_content', expand=True, noweakdefault=False, parsing=False, retparser=False):
             if expand or retparser:
    >            parser = self.expandWithRefs(value, cachename)
             if expand:
  File "/home/joel-cohen/code/waveos2/poky/bitbake/lib/bb/data_smart.py", line 430, in DataSmart.expandWithRefs(s='${@bb.fetch2.get_srcrev(d)}', varname='SRCPV'):
                 except Exception as exc:
    >                raise ExpansionError(varname, s, exc) from exc

bb.data_smart.ExpansionError: Failure expanding variable SRCPV, expression was ${@bb.fetch2.get_srcrev(d)}<mailto:$%7b at bb.fetch2.get_srcrev(d)%7d> which triggered exception AttributeError: 'FetchData' object has no attribute 'moddir'

I've fixed this with the following patch, which moves some code in the Hg fetcher to later in the urldata_init method, after some necessary variables have been initialized. I'm not sure if I'm alone in seeing this problem or not?


ALSO (I'm not sure if this is bitbake-related or poky-related): what is it that is supposed to create the $(BUILDDIR)/tmp/hosttools/hg symlink?

For some reason, this link is not created for me automatically. It works fine if I create it manually.


Thanks for any help,
Aaron
