Debian cares (see

for details).
I'll try applying this patch and seeing what happens some time this
week.

It just says you have to install the manpages in such-and-such a place,
but I don't have any. There, policy issue fixed :)
More seriously, it seems to me that the only reason we have these
manpages in the first place is because of emergent effects. *Maybe* I'm
wrong about someone using Git.pm as an external API, is that the case?
I was assuming this was more of a case where we were manifying the
equivalent of Documentation/technical/api-*.txt and shipping them as
user docs just because that's what EU::MM will do by default, and nobody
thought to stop it.
But sure, if we still want these I can just provide them, here's the
relevant generated perl.mak section:
POD2MAN_EXE = $(PERLRUN) "-MExtUtils::Command::MM" -e pod2man "--"
POD2MAN = $(POD2MAN_EXE)
manifypods : pure_all config \
Git.pm \
Git/I18N.pm \
Git/SVN/Editor.pm \
Git/SVN/Fetcher.pm \
Git/SVN/Memoize/YAML.pm \
Git/SVN/Prompt.pm \
Git/SVN/Ra.pm \
Git/SVN/Utils.pm
$(NOECHO) $(POD2MAN) --section=$(MAN3EXT) --perm_rw=$(PERM_RW) -u \
Git.pm $(INST_MAN3DIR)/Git.$(MAN3EXT) \
Git/I18N.pm $(INST_MAN3DIR)/Git::I18N.$(MAN3EXT) \
Git/SVN/Editor.pm $(INST_MAN3DIR)/Git::SVN::Editor.$(MAN3EXT) \
Git/SVN/Fetcher.pm $(INST_MAN3DIR)/Git::SVN::Fetcher.$(MAN3EXT) \
Git/SVN/Memoize/YAML.pm $(INST_MAN3DIR)/Git::SVN::Memoize::YAML.$(MAN3EXT) \
Git/SVN/Prompt.pm $(INST_MAN3DIR)/Git::SVN::Prompt.$(MAN3EXT) \
Git/SVN/Ra.pm $(INST_MAN3DIR)/Git::SVN::Ra.$(MAN3EXT) \
Git/SVN/Utils.pm $(INST_MAN3DIR)/Git::SVN::Utils.$(MAN3EXT)
I.e. we'd just need to create the mandir, then call pod2man.
However, even then we should consider what I've noted above and decide
which modules we really want to be shipping docs for, e.g. Git::I18n is
never going to be used by anyone external, nor is the Git::SVN stuff.
I think the only thing we're talking about shipping manpages for is
*maybe* just Git.pm itself, no?
I don't really care, so if others want to ship them all I'll just hack
it up. This just seemed like a bug to fix while I was at it.

Yeah, people really do use Git.pm as an external API.
Unlike e.g. something on CPAN, its API stability guarantees are not
great, so I am not saying I recommend it, but people have been using
it that way.
If we want to prevent this, then we should not be installing it in the
public perl module path. Or we should at least add a note to the
manpages we ship :) to recommend not using it.
Thanks,
Jonathan

I think a note in manpages is fine; maybe a load-time warning
to non-git.git users. We shouldn't be breaking other peoples'
code when they upgrade, though.

I'm very happy to see the recursive make invocation go away. The perl
makefile generation was one of the few places where parallel make could
racily get confused (though I haven't seen that for a while, so maybe it
was fixed alongside some of the other .stamp work you did).

Thanks for doing all this history digging. I agree that it doesn't seem
like there's really any reason to carry the complexity. Of your
functional changes, the only one that gives me pause is:

This could be a minor hiccup for people using Git.pm from other scripts.
But maybe only in funny setups? It seems like $prefix/share/perl5 would
be in most people's @INC unless they are doing something exotic.

I don't have a real opinion on this, but it sounds from the rest of the
thread like we should maybe build these to be on the safe side.

Yuck. :) I don't think there's a better wildcard solution within make,
though. And I'd rather see this than doing a $(shell) to "find" or
similar.
The other option is to actually list the files, as we do for .o files.
That's a minor pain to update, but it would allow things like
differentiating which ones get their documentation built.

TIL about pmc files. It sounds like they've had a storied history, but
should be supported everywhere.

I think so, but I'm not 100% sure. I'm hoping downstream maintainers
will catch this one if it's an issue, but in many cases it'll just work,
e.g. I have /usr/share/perl5 in /usr/bin/perl's @INC on Debian even
though that's not the target install dir EU::MM would have picked.
Whether there's perl configurations that don't have $prefix/share/perl5
in @INC at all I don't know.

Indeed, we'll need to ship at least the Git.3pm manpage.
I tried coming up with something that worked like the current
Makefile.PL but couldn't figure out how I'd generate
a::file::like::this.3pm from a/file/like/this.pm
So I hacked up the following minimal patch to just build Git.3pm:

Maybe this approach is bad, I don't know. This might be a better fit for
Documentation/Makefile since it has some "man" logic already, but do we
want it to be depending on stuff in ../perl?
On my Debian install I have these from existing Git:
/usr/share/man/man3/Git.3pm.gz
/usr/share/man/man3/Git::I18N.3pm.gz
/usr/share/man/man3/private-Error.3pm.gz
We definitely don't want the 2nd two ones to have manpages, that was
always an accident. git-svn has a few more:
/usr/share/man/man3/Git::SVN::Editor.3pm.gz
/usr/share/man/man3/Git::SVN::Fetcher.3pm.gz
/usr/share/man/man3/Git::SVN::Memoize::YAML.3pm.gz

/usr/share/man/man3/Git::SVN::Ra.3pm.gz
/usr/share/man/man3/Git::SVN::Utils.3pm.gz
But those all say that they're internal API only. So maybe this hack of
mine is fine. What do others think?
In any case, a solution that tries to build all the manpages with a glob
is going to suck currently since some of them have POD, and others
don't, which gets us into the headache of trying to distinguish whether
something has POD v.s. whether we just had pod2man fail.
So it seems better just to whitelist the man3 pages that get build,
which to me seems like just one currently.

As a datapoint, I've seen it fairly regularly with -j8 in 2.15.1
builds from a clean tree that I've been doing recently. I'm looking
forward to not having to make the choice between "maybe run it twice"
or "compile slower" -- this looks great!

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're genreated (see
"perldoc -f require").
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't man pages for all of the perl modules as we used t, only
Git(3pm). As discussed on-list[8] that we were building installed
manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

Per my reading of the list discussion this should be OK to apply. We
now build the manpage for Git.pm (but no other *.pm, as discussed).
Aside from the improved commit message & POD building I updated the
INSTALL instructions & we now build stuff in perl/build/{lib,man}
instead of just PM stuff in perl/build/lib. tbdiff with v2 follows:

There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on

Well the thing is that I cannot queue this and Dan's at the same
time, while both of these topics are expected to be in flux. For
today's pushout, I tentatively kicked out Dan's relative path series
and queued this one to see how well it works with the rest of the
system, after giving this patch another round of reading.
It seemed that Dan was happy with (an earlier draft of?) this
build procedure simplification patch, so hopefully we can solidify
this one reasonably quickly and ask the relative path series to be
rebuilt on top of it?
Thanks.

Sounds good to me! I'm in no rush, and if this is moving forward I'm more
than happy to wait for it to land and rebase on top.
I didn't want to weigh in too heavily on the actual details of this patch
since I think the majority stakeholders are the folks who maintain the Perl
subsystem and those who build distribution packages. My work on Perl only
touches installation as a means to an end, and avarab@'s work does simplify
this for me.
Cheers, and thanks!

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't build man pages for all of the perl modules as we used to,
only Git(3pm). As discussed on-list[8] that we were building
installed manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

This fixes the test failure we had on 32 bit Linux due to v2. That
error had nothing to do with 32 bit per-se, it was just a logic error
in the fallback logic if the system didn't have an Error.pm, and
evidently the 32 bit environment doesn't have that installed.
This also incorporates Junio's typo/grammar fixes of my commit
message, tbdiff with v2:

I don't know what I was thinking when I wrote this, but this logic
should be fully robust, and I've confirmed that all tests pass

<big snip>
I would like to request that the we be careful that the git builds do not introduce arbitrary dependencies to CPAN. Some platforms (I can think of one off the top, being NonStop) does not provide for arbitrary additions to the supplied perl implementation as of yet. The assumption about being able to add CPAN modules may apply on some platforms but is not a general capability. I am humbly requesting that caution be used when adding dependencies. Being non-$DAYJOB responsible for the git port for NonStop, this scares me a bit, but I and my group can help validate the available modules used for builds.
Note: we do not yet have CPAN's SCM so can't and don't use perl for access to git anyway - much that I've tried to change that.
Please keep build dependencies to a minimum.
Thanks for my and my whole team.

I think you should be happy with this patch then, and it doesn't add any
more CPAN dependency than before, and sets up a framework (as discussed
in [1]) where we can use more CPAN modules while not requiring packagers
such as yourself to package CPAN modules.
However, it doesn't sound believable to me that even on NonStop you
can't install any CPAN modules whatsoever.
That would also mean that this patch doesn't work for you, because it
means that you either don't have anything resembling a hierarchical
filesystem on which git can be installed in the first place (in which
case it wouldn't work), or perl doesn't have an @INC to search through
perl libs on on NonStop. What does:
perl -V
Return for you on that system?
If this patch works, and if at the bottom of `perl -V` you see some
directories which you could write a package to drop some static *.pm
files, then you can grab a *.tar.gz from CPAN such as the one for
Error.pm[2] and arrange for the *.pm files contained within its lib/
directory to be dropped into one of those @INC directories.
It may be that some aspect of the CPAN toolchain is broken for you, or
even ExtUtils::MakeMaker, but you typically don't need that to package
non-XS perl modules, certainly not any of the ones we've discussed
possibly bundling up in git.git on-list recently. As a (very occasional)
contributor to perl.git I'd be interested to know if that's what you
mean is broken, and if so see if it could be fixed for you.

This patch (currently in origin/next) makes a ton of tests from our test
suite fail for me on pretty standard systems (Fedora 27, CentOS 7.4.1708).
Is there anything I'm supposed to do differently now to make our test
suite run? If yes then a clear and short hint in the patch description
would me more than approriate.

Interesting. I'll have to try building next. I was going
to wait until the first 2.16.0 rc for a full test.
I did apply this patch on top of 2.15.1 on 12/10 and built
an rpm locally for fedora (only f26 though). I didn't see
any test failures, which is why I thought I'd wait for
2.16.0-rc0 to test further.
FWIW, the minor spec file changes I made (against fedora's
git package master branch) are here:
https://src.fedoraproject.org/fork/tmz/rpms/git/branch/perl-makefile
The only change in the patch since I tested it is:
+-modules += Git/Packet
in perl/Makefile.
I don't think any of these changes to the rpm spec file or
the Git/Packet addition in modules look like they'd affect
the test suite, but it's early here and I could be wrong.
I'll try to test a build of next soon to see if I get
similar failures on Fedora/CentOS.

This is a bug in my patch, I can reproduce it on CO7. Will figure out
what's going on there...

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't build man pages for all of the perl modules as we used to,
only Git(3pm). As discussed on-list[8] that we were building
installed manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

Here's a hopefully final version. The only difference with v3 is:
- local @_ = ($caller, @_);
+ unshift @_, $caller;
As it turns out localizing @_ isn't something that worked properly
until
https://github.com/Perl/perl5/commit/049bd5ffd62b73325d4b2e75e59ba04b3569137d
That commit isn't part of the 5.16.3 version that ships with CentOS 7,
which explains why Michael J Gruber had issues with it. I've tested
this on CentOS 7 myself, it passes all tests now.

Thanks for tracking this down!
FWIW, I applied this version to next and tested it with
CentOS 6 and 7. The tests pass on both (though there are
some unrelated failures on CentOS 6 in t5700-protocol-v1,
which I haven't looked into further yet).
I also applied this patch to 2.15.1 and ran the tests in the
Fedora build system for all fedora and epel releases, which
also passed (though with some spurious git-svn failures on
x86_64 in fedora 28, AKA rawhide).
The .pmc extensions seem to cause rpm to fail to parse the
files for rpm 'provides' as it normally would. This causes
scripts like git-send-email which generates a 'requires' on
Git::Error to fail to find anything which provides it.
I'm not familiar with the .pmc extenstion. Searching the
fedora repositories, there is only one other package - and
one file within it - which has a .pmc extension.
(The package is perl-test, the file is
/usr/libexec/perl5-tests/perl-tests/t/run/flib/t2.pmc.)
Perhaps it's a bug in rpm's perl dependency generator, but
I'd like to think that git wouldn't be the first package to
find it.
Is the .pmc extension important to ensure these files are
loaded in the right order? Since they're all in the Git
namespace, I don't imagine there should be anything else in
@INC which would be provided by the system or another
package.
Pardon my ignorance if I've missed the obvious (I haven't
fully read "perldoc -f require" which you referenced in the
commit message).

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt.
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't build man pages for all of the perl modules as we used to,
only Git(3pm). As discussed on-list[8] that we were building
installed manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

This *.pmc thing is just me being overly clever. Here's a v5 that gets
rid of it. Diff with v4:

So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)

- from *.pm to *.pmc just to indicate that they're generated (see
- "perldoc -f require").

While I'm at it, change the fallback for Error.pm from being something

Aside from the tooling issues you mentioned:
* It's obscure enough that lots of editors won't know *.pmc is perl
for syntax highlighting etc.
* Even though this use case works, perl really expects you to have a
*.pm file alongside the *.pmc, so e.g if there's an error it
*reports the *.pm path, even though no such file exists. I.e. it's
*for compiler-generated files where the compiled version could have
*changed line numbers etc.

No worries. It is a rather large CC list at this point. :)

Ahh, thanks for the additional details on this.

Without the .pmc extensions, rpm picks up the perl
dependencies, which is good. But an additional build/lib
dir is created, which ends up in $perllibdir after install.
Here's an extract from a local build:
mkdir -p perl/build/lib/build/lib/ && \
sed -e 's|@@LOCALEDIR@@|/usr/share/locale|g' < perl/build/lib/Git.pm > perl/build/lib/build/lib/Git.pm
mkdir -p perl/build/lib/build/lib/Git/ && \
sed -e 's|@@LOCALEDIR@@|/usr/share/locale|g' < perl/build/lib/Git/IndexInfo.pm > perl/build/lib/build/lib/Git/IndexInfo.pm
mkdir -p perl/build/lib/build/lib/Git/ && \
sed -e 's|@@LOCALEDIR@@|/usr/share/locale|g' < perl/build/lib/Git/SVN.pm > perl/build/lib/build/lib/Git/SVN.pm
mkdir -p perl/build/lib/build/lib/Git/ && \
sed -e 's|@@LOCALEDIR@@|/usr/share/locale|g' < perl/build/lib/Git/Error.pm > perl/build/lib/build/lib/Git/Error.pm
mkdir -p perl/build/lib/build/lib/Git/ && \
sed -e 's|@@LOCALEDIR@@|/usr/share/locale|g' < perl/build/lib/Git/I18N.pm > perl/build/lib/build/lib/Git/I18N.pm
When PMFILES and PMCFILES matched .pm and .pmc respectively,
the glob didn't match duplicated files under build/lib, so
this wasn't an issue. I'm not sure where this is best
fixed. The build/lib dir could be moved outside of perl or
it could be made .build/lib to avoid the wildcard match,
perhaps.
Building with perllibdir=/usr/share/perl5/vendor_perl
results in:
/usr/share/perl5/vendor_perl/Git
/usr/share/perl5/vendor_perl/Git.pm

/usr/share/perl5/vendor_perl/build/lib/Git/IndexInfo.pm
/usr/share/perl5/vendor_perl/build/lib/Git/SVN.pm
Note that not all of the .pm files are matched, which I
believe is due to the glob matches only going 4 levels deep
under the perl dir.
Thanks,

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt.
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't build man pages for all of the perl modules as we used to,
only Git(3pm). As discussed on-list[8] that we were building
installed manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

Ouch, that's a stupid mistake of mine. Didn't consider that changing
it from *.pm to *.pmc would of course impact that glob match.
This fixes it, changes against v5:

I.e. let's keep calling it "build" for consistency with other stuff
and so "ls" will show it, but just alter the glob so we'll only match
modules like Git{,::*}. I don't think we'll ever add anything outside
that namespace, so this seems like the best solution.
With this "make install" gives the expected results, i.e. no build/
directory in perllibdir.

Sounds good. While it might not have been too bad to have a
hidden dir for build artifacts, using the more explicit glob
pattern is much nicer.
I'll use this locally and let you know if I notice any
issues. Thanks for working on this.

Sincerely sorry for off-topic, I just wonder why this section of INSTALL
uses the backticks for command substitution. Is there a shell which does not
support the alternative form $(...) but has all the rest of the used syntax?

Thanks, but I thought the patch was already in 'next' for a week or
more and it's time to refine incrementally.
Here is the difference as I see between what we already have and
this update, and a proposed summary.

Subject: perl: avoid *.pmc and fix Error.pm further
The previous round tried to use *.pmc files but it confused RPM
dependency analysis on some distros. Install them as plain
vanilla *.pm files instead.
Also "local @_" construct did not properly work when goto &sub
is used until recent versions of Perl. Avoid it (and we do not
need to localize it here anyway).

When I read this back on the 22nd I missed that you were waiting on my
feedback on this. Just saw What's Cooking now. Yes, LGTM:

This appears to have broken a build with INSTLIBDIR set.
$ head -2 /usr/local/git/current/libexec/git-core/git-add--interactive
#!/usr/bin/perl
use lib (split(/:/, $ENV{GITPERLLIB} || ":/Applications/Xcode.app/Contents/Developer/Library/Perl/5.@{[sub{use Config; $Config{api_version}}->()]}/darwin-thread-multi-2level" || "/usr/local/git/current/share/perl5"));
(forgive the hackiness there).
Is there a reason we don't do
INSTLIBDIR='$(perllibdir_SQ)' && \
INSTLIBDIR_EXTRA=... &&
INSTLIBDIR=...
and
use lib ... || "'"$$INSTLIBDIR"'"));=' \
?
Thanks,

Subject: perl: treat PERLLIB_EXTRA as an extra path again
PERLLIB_EXTRA was introduced in v1.9-rc0~88^2 (2013-11-15) as a way
for packagers to add additional directories such as the location of
Subversion's perl bindings to Git's perl path. Since 20d2a30f
(Makefile: replace perl/Makefile.PL with simple make rules,
2012-12-10) setting that variable breaks perl-based commands instead:
$ PATH=$HOME/opt/git/bin:$PATH
$ make install prefix=$HOME/opt/git PERLLIB_EXTRA=anextralibdir
[...]

Empty compile time value given to use lib at /home/jrn/opt/git/libexec/git-core/git-add--interactive line 2.
Removing the spurious ":" at the beginning of ":$PERLLIB_EXTRA" avoids
the "Empty compile time value" error but with that tweak the problem
still remains: PERLLIB_EXTRA ends up replacing instead of
supplementing the perllibdir that would be passed to 'use lib' if
PERLLIB_EXTRA were not set.
The intent was to simplify, as the commit message to 20d2a30f
explains:

Restore the previous code structure to make PERLLIB_EXTRA work again.
Reproducing this problem requires an invocation of "make install"
instead of running bin-wrappers/git in place, since the latter sets
the GITPERLLIB environment variable, avoiding trouble.

Here it is in patch form.

This obviously makes perfect sense if the intent is to add this lib dir
instead of it being a replacement (as is clear from this being an issue
you're noting).
With the benefit of hindsight in re-reading the commit + this report I
can see that it *should* be that way, but I assumed it was the other way
around when I wrote this up.
Thanks!
