“Incompatible Archive” in FTP upgrading after r11025 (pclzip)

[demetris]

r11024 works OK.

In r11025 I get:

Downloading update from...

Unpacking the update.

Incompatible Archive.

Tested on two different servers/setups.

Please let me know if you need more info.

wherefrom is this? wordpress.org, or your own server?

I ask, because I had the same issue on my end at one point, and zipping from the server (rather than from my desktop) fixed it.

Could be the pclzip upgrade, or it could be network problems. I used to see this with incomplete downloads due to timeout that somehow didn't trigger a download error.

I switched class-pclzip.php a few times between r11024 and r11025 and the problem (Incompatible Archive) only occurs in r11025, consistently.

@Denis-de-Bernardy: I’m upgrading automatically, from wp.org. I click “upgrade automatically” on a plugin, then, on the Upgrade Plugin page, I click Proceed, and I get the message.

See #9464

(In [11038]) Use dist pczlip. see #9615 #9464

I updated pclzip to the distribution version, without any of our whitespace changes, just in case something went wrong there. If that doesn't help, we can try 2.6 and then revert back to 2.5 if need be.

Problem persists with distribution version of pclzip 2.7. (As before, reverting class-pclzip.php to r11024 solves the problem.)

Maybe we should report this upstream?

Replying to demetris:

Maybe we should report this upstream?

please do, if you know where.

A new version of pclzip came out today: 2.8. I tried it and it has the same problem.

@Denis:

The pclzip readme gives this address for bug reports:

​http://sourceforge.net/tracker/?group_id=40254&atid=427564

But I think I’ll leave the bug-reporting to someone who understands how this thing works. :-)

This is working for me on a Windows XP machine.. About to test with a Linux machine..

Confirmed on a linux x64 server.

PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

is the error. Reminds me of the x64 dragons in #6236 Which i thought had been fixed in PclZip..

Infact.. Its the exact same damn issue, The x64 patch which was submitted upstream is not in the latest versions. re-apply [7314] and everything works.

Thanks, DD32!

I applied [7314] to pclzip 2.8 (released today, 2009-04-22) and it works again.

I’m attaching the patch.

Updates class-pclzip.php to pclzip v2.8 and reapplies patch 7314

seems the sourceforge bug tracker has no trace of the above-mentioned issue though.

(In [11056]) Update pclzip to 2.8 and apply x64 patch. Props demetris. fixes #9615

seems the sourceforge bug tracker has no trace of the above-mentioned issue though.

Thats because that tracker is virtually dead. I think 2 of us contacted the author via Email (And got positive responses) tho..
