py25-htmldocs: /bin/chmod: Argument list too long

[lminder@…]

I cannot install py25-html due to too long argument list to chmod when staging.

Example:

# port install py25-htmldocs
--->  Computing dependencies for py25-htmldocs
--->  Staging py25-htmldocs into destroot
Error: Target org.macports.destroot returned: shell command failed (see log for details)
Log for py25-htmldocs is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_py-htmldocs/py25-htmldocs/main.log
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

The relevant extract from the log is:

:info:destroot sh: /bin/chmod: Argument list too long
:info:destroot shell command "chmod a+r `find /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_py-htmldocs/py25-htmldocs/work/destroot/opt/local/share/doc/python25-doc -type f`" returned error 126
:error:destroot Target org.macports.destroot returned: shell command failed (see log for details)

It seems it would be possible to fix this by using a for loop, something like "for i in `find blah` ;do chmod a+r "$i" ; done". I haven't tried, because I don't know how to correctly quote the $ in tcl.

I'm not sure why I'm seeing this error while apparently most other people aren't.

The version of py25-htmldocs is 2.5.4_1. Curiously, 2.5.4_0 seemed to install fine, although I can't retry now.

We shouldn't be using "system ... chmod ... find" at all; we have native Tcl commands for this: fs-traverse, file attributes -permissions, etc.

The directory path where MacPorts ends up building the port may be longer than other users'.

Yes, because that was the change made in 2.5.4_1; see r84554.

Actually, with py25-htmldocs, I see the problem too; I don't with py27-htmldocs. py25-htmldocs installs 1605 files whereas py27-htmldocs installs only 1000 files, so py25-htmldocs' argument list would have been much longer. Probably nobody tested py25-htmldocs. But anyway it's fixed now.

Thanks for fixing it! I'm not a tcl-er, so I was looking for any fuctional way to accomplish the task... You're correct -- I hadn't tested py25-htmldocs, just the others.
