Hi I getting this error: "configure: error: cannot link with -lczmq, install libczmq.", on ./configure && make check. I have installed libzmq, czmq and libsodium right before compilation, so it's the latest from repo. How can I fix it?

When I build filemq, the file libfmq.la contains an incorrect path to czmq.

I run configure like so:

./configure --with-libzmq=/usr/local/libzmq3 --with-libczmq=/usr/local/czmq --prefix=/usr/local/filemq

Then I run make check install

Inside /usr/local/filemq/lib/libfmq.la I see this line:

dependency_libs=' -L/usr/local/czmq/lib -L/usr/local/libzmq3/lib -lm -lcrypto /usr/local/lib/libczmq.la /usr/local/libzmq3/lib/libzmq.la -lrt -lpthread'

/usr/local/lib/libczmq.la doesn't exist, and should be instead /usr/local/czmq/lib/libczmq.la

This was causing the Zyre build to fail. Correcting the path above fixed my issue.

My environment is Fedora 18 Linux, x86_64

Hello. I cannot find the .gsl files anywhere. I see that they were originally committed by @hintjens under /model, but that no longer exists.

Did the code generation behavior change at some point?

Building fmq on 10.7/clang, i get few deprecated function in use. This is specific to osx and i don't know why those openssl functions are deprecated on 10.7.

Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic

Start a server, start a client, then kill the server. The client does not detect the dead server (with or without heartbeat=1). Re-starting the server still leaves the original client running, but unconnected.

It appears as if zmq_poll does not properly detect broken connections (but I'm not absolutely sure of this).

Hello,
when I run "make check", I got the following error. Would you please help me with that?
Thanks

Problem: If I generate the protocol files by calling ./generate in filemq/model the compilation of the library breaks. Error message:

fmq_msg.c:772:1: error: conflicting types for 'fmq_msg_send_ohai'
In file included from fmq_msg.c:27:0:
../include/fmq_msg.h:108:5: note: previous declaration of 'fmq_msg_send_ohai' was here

The generated files differ considerably to the ones in master.

Any ideas?

If you start up a server process serving files from the physical directory '/tmp' to the virtual directory '/xyz/foo', then set up a client subscribing to the virtual directory '/xyz/foo' into the physical directory '/home', the files are written to the directory '/home/xyz/foo'.

This seems counter-intuitive. I would expect that, in the above scenario, if you create a file '/tmp/file' it should be served to '/home/file', since I'm subscribing to the same virtual directory. Perhaps I misunderstand, but it would seem to me that what's wanted is a clone of the contents of '/tmp' from the server into '/home' of the client.

Hello,

This might a trivial issue ... but i am not able to compile filemq.

I have tried with :
git clone git://github.com/hintjens/filemq.git
cd filemq
./autogen.sh
./configure && make check
sudo make install
sudo ldconfig

as specified, after installing libsodium, libzmq and czmq in /usr/local . (from latest git)
I also tried with stable version of libzmq (4.0.4)
and czmq tag 2.2.0

What is my mistake ? Sorry about my poor C skills ... and thanks for your help.

I tried to build filemq and go this error:

Let me know how to fix this so I can help and also create a release version - last one was 4 years ago

There are a lot of references to deprecated czmq API's in FileMQ. Not sure if it will be acceptable, but I am working on fixing this for the c code. I do not have any expertise for Java.

I followed the directions for downloading and installing:

git clone git://github.com/hintjens/filemq.git
cd filemq
./autogen.sh
./configure && make check

I got the following errors:

Hello,

All source files, except src/filemq_client.c and src/filemq_server.c, has MPL Version 2.0 license header. LICENSE file has MPL version 2.0 text. That is OK.

But on github webpage top right corner GPLv3 license is mentioned. And there are two license files COPYING and COPYING.LESSER which says GPLv3 and LGPLv3. This seems to be inconsistent.

It seems that filemq has MPL version 2.0 license because almost all sources has MPL Version 2.0 license header. But could you please clarify license removing inconsistency ?

Thanks,
Rahul

MSVC has the following issues:

• Requires explicit casting
• Doesn't support strcasecmp
• Name conflict with member variable "virtual" (used in fmq_patch)
• Name conflict with local varible "new" (used in fmq_dir)

I propose the following changes:

• Cast all necessary variables
• Define strcasecmp as _stricmp for Win32
• Rename "virtual" to "virtualf" (for virtual file name)
• Rename "new" to "_new" to avoid these conflicts

I've got these changes ready in my fork, can we discuss?

When I try to build filemq, I hit the following error:

fmq_dir.c: In function 'fmq_dir_remove':
fmq_dir.c:433:9: error: implicit declaration of function 'zfile_rmdir' [-Werror=implicit-function-declaration]
cc1: all warnings being treated as errors
make[2]: *** [fmq_dir.lo] Error 1

I built and installed libzmq and czmq and zfile_rmdir() isn't defined anywhere. I pulled everything from the git repositories, so I have the latest source. Is there perhaps an older revision of something I should be using?

Hi,

From: src/fmq_server_engine.inc:
//  Set log file prefix; this string will be added to log data, to make
//  log data more searchable. The string is truncated to ~20 chars.

The code intend to truncate the string to ~20 chars but this behaviour
throw an error with new compiler (gcc >= 7.1).

See:
http://autobuild.buildroot.net/results/434/43452430edf44cbcef6ea3a5ab80ac0ff406208f

This can be avoided by disabling this warning with -Wno-format-truncation.

Best regards,
Romain

I have the latest versions of libzmq, czmq, and filemq all building on Windows 7, and am running filemq_selftest using two separate processes, one as the server via the -s option, and the other as the client.

When the server starts, it creates .\fmqroot\send. I drop a file in that directory.
When I start the client, they start chattering to sync up.

On receipt of the icanhaz message from the client, the server gets to this point in the call stack:

store_client_subscription()
    mount_sub_store()
        sub_patch_add()

...in the call to sub_patch_add(), the server first calls zdir_patch_digest_set(), which apparently intends to generate a SHA1 hash for the file I added. However, to generate the hash, it seems to want to use openssl to do this, which is not currently available on my system, and wasn't listed as a build dependency for czmq, where zdir_patch_digest_set() is implemented.

The result is that, since there is no implementation available to calculate the SHA1 hash, zdir_patch_digest_set() is a no-op, so the digest field of __zdir_patch_t is left with a value of 0.

Since this file is a new entry in the server cache, it calls zhash_insert(), using the result of zdir_patch_digest() as the key value, which has a value of 0. zhash_insert then fails on an assertion requiring a non-zero value for the key.

Seems like the dependency on OpenSSL for filemq to operate correctly should be explicitly mentioned so that the czmq libraries can be built properly so this error does not occur.

Or, is there some other alternative I can use as a workaround in the meantime?

Also, it seems like the selftest for czmq and/or filemq should include test functions that would catch this problem.

Hi,
got a core dump when deleting one file from the original-directory when run "filemq" or "track":
HUGZ:
lt-filemq: zhash.c:219: zhash_insert: Assertion `key' failed.
Aborted (core dumped)

gdb shows:
#4 0x00007ffff7bad4f9 in zhash_insert (self=0x7ffff0002650, key=0x0, value=0x7ffff00046c0) at zhash.c:219
#5 0x00007ffff7deb0a7 in sub_patch_add (self=0x7ffff0001a80, patch=0x7ffff0178cd0) at fmq_server.c:329

0x00007ffff7deca4b in mount_refresh (args=, ctx=, pipe=) at fmq_server.c:409

in #5, the patch->op = patch_delete; patch->digest = 0;
looks like the sub_patch_add() doesn't handle the patch_delete case correctly?

Thanks,
-Steve

When I ran the make check command, this message was emitted

I reviewed the source code (fmq_hash.c) and I saw that the buffer was declared as a local variable. In this way the buffer is not alligned on 64-bit boundary.

In order to fix this I declared the buffer as global variable. Ugly but works for me.

// --------------------------------------------------------------------------

memset (buffer, 0xAA, 1024);

fmq_hash_t *hash = fmq_hash_new ();
fmq_hash_update (hash, buffer, 1024);
byte *data = fmq_hash_data (hash);
size_t size = fmq_hash_size (hash);
assert (data [0] == 0xDE);
assert (data [1] == 0xB2);
assert (data [2] == 0x38);
assert (data [3] == 0x07);
fmq_hash_destroy (&hash);

printf ("OK\n");
return 0;

When a new connection is made with RESYNC=1, the server ignores the cache and sends all files. It should only send the files not already present on the client.

The check should (probably) be done in mount_sub_store (fmq_server.c:464-473).

Problem: filemq does not compile on Ubuntu out of the box.

fmq_selftest.c:30:5: error: unknown type name ‘Bool’
fmq_selftest.c:33:19: error: ‘TRUE’ undeclared (first use in this function)

Solution: use bool type from C99
