trouble during parsing

trouble during parsing

[Andreas Müller]

Hi,

with current bitbake master I get

ERROR: Command execution failed: Traceback (most recent call
last):#########################################################
                              | ETA:  00:00:17

    if not self.parser.parse_next():
  File "/home/andreas/oe-core/sources/bitbake/lib/bb/cooker.py", line
1703, in parse_next
    self.virtuals += len(result)
TypeError: object of type 'ExpansionError' has no len()

Any ideas?

Andreas

Hmm, looks like it's returning the exceptions rather than raising them, for
some reason, but that doesn't make much sense — the pool code always raises
any exceptions from its imap iterator's next() method.

I'm hitting this as well with
poky:dde7a481354d5b0539762109bdfaaba6f85f879b, meta-ti and pandaboard
as my machine.

Ach, should have updated my email. Seems reverting
0a99563a4ea270594fd9a61da46f9387fb79dc66 cleared up the issue.

I have two machines (Fedora 14  / Fedora 15)  both reverted
0a99563a4ea270594fd9a61da46f9387fb79dc66 and both worked fine during
weekend.

Just a guess: Last week when arago git was down I saw errors during
parsing for a recipe I never used. This was with a revision of bitbake
a bit earlier than HEAD - that caused me to update. After sending a
message to meta-ti I could work during weekend. Now it seems arago is
down again:

$ git clone git://arago-project.org/git/projects/u-boot-keystone.git
Cloning into u-boot-keystone...
fatal: read error: Connection reset by peer

and bitbake -DD gives

In the recipe u-boot_2013.01.bb I find SRCREV = "DEV.MCSDK-03.00.00.07"

which is not a commit ID and causes a git ls-remote during parse

Is it possible that this error occurs when a git SRC_URI server closes
connection unexpected?

Hi Andreas,

I have the same issue and your guess is correct. The problem is that
Arago servers are down so "git ls-remote" is failing and this makes
the BitBake task to fail as well.

Now about the why is been used tag names instead of just commits IDs
so a "git ls-remote" call is needed, this is because some git trees in
arago are been rebased overwriting the commit IDs.

You may take a look to Robert P. J. Day email "[meta-ti] objections to
replacing git SRCREV tag names with actual	hash IDs?" [1] to get a
better understanding of this.

Best regards,
javier

Hi Andreas,

I have the same issue and your guess is correct. The problem is that
Arago servers are down so "git ls-remote" is failing and this makes
the BitBake task to fail as well.

Now about the why is been used tag names instead of just commits IDs
so a "git ls-remote" call is needed, this is because some git trees in
arago are been rebased overwriting the commit IDs.

You may take a look to Robert P. J. Day email "[meta-ti] objections to
replacing git SRCREV tag names with actual	hash IDs?" [1] to get a
better understanding of this.

Best regards,
javier

One additional note: With current bitbake there are configurations
which cause a full parse on every build [1]. Is it possible that
arrago-git dies for the flood of  git ls-remote?

Re: [meta-ti] trouble during parsing

[Trevor Woerner]

If the purpose of the ls-remote is to match a tag with a hash,
wouldn't it be easier to just:

    cat .git/refs/tags/<tagid>

?

And if the purpose of knowing the tagid is to use that version of the
code, wouldn't it be easier to just:

    git checkout <tagid>

?

If the git clone hasn't happened yet, this doesn't work.

That isn't the only purpose.

Additionally, the problem is that tags can move and the revid
will change.  Hence the need to probe the source GIT for the answer.

If a tag has moved then a

    $ git fetch --tags

would update your local tag refspecs with the updated information, wouldn't it?

All,

First of all, sorry for the troubles with the server connection. It should be 
fine now.

Second, there is a hard limit of maximum allowed simultaneous git connections 
on the server due to limited resources, and the limit was maxed out. The 
server was still running fine, but it would not accept any more connections. 
It looked like a DoS attack - connections were still running and packing data. 
Most of the connections were from China - I'm wondering how long does it take 
to clone a large git tree from over there...

Anyway, there are some fixes related to this problem being discussed and will 
be implemented shortly...

And BTW, bitbake's git-ls-remote is very fragile and we've seen it failing on 
a good server connection (even with kernel.org and github.com) very easily. 
There needs to be a re-try count implemented for that code as well...

The real question is what are the expansion errors about here.  This is probably not the right way to fix it, but it at least allows you to see what is behind the expansion error:
