[PATCH] libsysfs changes for sysfsutils 0.3.0 Here's the patch to up the library to the sysfsutils-0_3_0 level. The following changes: 1) adds class name to sysfs_class_device structure 2) adds bus to sysfs_device 3) gets rid of code that made assumptions as to bus addresses being unique across buses, which isn't the case. I still owe you: 1) change getpagesize->sysconf. This is in the CVS tree and part of other changes we're currently testing. Patch will follow. 2) you need a function to get a sysfs_class_device's parent. We hadn't considered class devices to have parents, the one example of a multilevel is the block class. We will add this function and send the patch to you.

[PATCH] patch for libsysfs sysfs directory handling Here's a quick patch to: 1) Add an environment variable "SYSFS_PATH" that libsysfs will check for when getting mount point before searching system's sysfs mount point. 2) A quick fix to sysfs_get_link where the bug was. I have tested this out with libsysfs and with udev. I couldn't test with klibc because I haven't got the tree to build with klibc without my changes either. I made the link but get an error finding linux/linits.h. I will figure that out. Please have a look at the patch. If it's agreeable, please test it. I really want to add some generic path manipulation functions for the sysfs_get_link error, rather than my patch's hack. But, I haven't had time yet to do that. You really sounded like you needed this for testing, so I'm sending it out to you. I should probably add a function to set the env variable(?).

[PATCH] pre-libsysfs-0.4.0 patch I am sending you a pre-release patch. It's everything that's in our current CVS tree. It adds the functionality you've been looking for. Please play with this before checking it into your tree, I'd like to know if it's ok with you or if you find problems. I have tested this out with test.all and the perl regression test. Let me know what you think. Still need to do more testing for our work and add some more functions related to the changes. I've gone into namedev.c and udev-add.c to make the necessary changes in line with the library. I have not gone and edited any of the "extras". Changes: 1) Libsysfs object structures work more as handles now, their included directories or devices are labeled private. If you need attributes from a sysfs_class_device, call the available function and don't access the directory directly. Same holds true for a sysfs_class_device sysfs_device. Do not access the link directly but call the function sysfs_get_classdev_device() instead. We only populate entries upon request, makes things faster and uses less memory. 2) Added sysfs_get_classdev_parent() as requested. 3) Changed getpagesize to sysconf. 4) Added sysfs_refresh_attributes function for refreshing views of attribute lists. We still need to add refresh for links and subdirs. All udev needs to do is keep calling sysfs_get_classdev_attr() and that will internally call the refresh routine.

[PATCH] another patch for path problem The quick patch I sent you yesterday fixes it in one location, but there are other points in the library that calls sysfs_get_mnt_path. We need to address all the areas in the library where paths are used. The following patch is a band-aid until we can get a proper path management in the library.

[PATCH] pre-libsysfs-0.4.0 patch I am sending you a pre-release patch. It's everything that's in our current CVS tree. It adds the functionality you've been looking for. Please play with this before checking it into your tree, I'd like to know if it's ok with you or if you find problems. I have tested this out with test.all and the perl regression test. Let me know what you think. Still need to do more testing for our work and add some more functions related to the changes. I've gone into namedev.c and udev-add.c to make the necessary changes in line with the library. I have not gone and edited any of the "extras". Changes: 1) Libsysfs object structures work more as handles now, their included directories or devices are labeled private. If you need attributes from a sysfs_class_device, call the available function and don't access the directory directly. Same holds true for a sysfs_class_device sysfs_device. Do not access the link directly but call the function sysfs_get_classdev_device() instead. We only populate entries upon request, makes things faster and uses less memory. 2) Added sysfs_get_classdev_parent() as requested. 3) Changed getpagesize to sysconf. 4) Added sysfs_refresh_attributes function for refreshing views of attribute lists. We still need to add refresh for links and subdirs. All udev needs to do is keep calling sysfs_get_classdev_attr() and that will internally call the refresh routine.

[PATCH] libsysfs 0.4.0 patch Ananth released sysfsutils 0.4.0 last night, I'm sure you saw the email. Here's a patch with the latest changes from the pre-patch I already gave you. It includes sysfs_get_device_parent(), which you said you needed. I've run your test scripts and I've built scsi_id. Please play around with this and check it out. There are quite a few changes. Please do not access structure pointers, like sysfs_device's parent, directly like dev->parent. Please use the "get" function to retrieve. The functions load things on demand and refresh views under the covers.

[PATCH] pre-libsysfs-0.4.0 patch I am sending you a pre-release patch. It's everything that's in our current CVS tree. It adds the functionality you've been looking for. Please play with this before checking it into your tree, I'd like to know if it's ok with you or if you find problems. I have tested this out with test.all and the perl regression test. Let me know what you think. Still need to do more testing for our work and add some more functions related to the changes. I've gone into namedev.c and udev-add.c to make the necessary changes in line with the library. I have not gone and edited any of the "extras". Changes: 1) Libsysfs object structures work more as handles now, their included directories or devices are labeled private. If you need attributes from a sysfs_class_device, call the available function and don't access the directory directly. Same holds true for a sysfs_class_device sysfs_device. Do not access the link directly but call the function sysfs_get_classdev_device() instead. We only populate entries upon request, makes things faster and uses less memory. 2) Added sysfs_get_classdev_parent() as requested. 3) Changed getpagesize to sysconf. 4) Added sysfs_refresh_attributes function for refreshing views of attribute lists. We still need to add refresh for links and subdirs. All udev needs to do is keep calling sysfs_get_classdev_attr() and that will internally call the refresh routine.

[PATCH] new version of libsysfs patch Here's the patch applying the latest libsysfs. - adds the latest libsysfs code to udev * new code includes dlist implementation, a generic linked list implementation. Needed our own because LGPL * rearranged structures * provided more functions for accessing directory and attributes - gets rid of ->directory->path references in namedev.c - replaces sysfs_get_value_from_attributes with sysfs_get_classdev_attr

[PATCH] libsysfs changes for sysfsutils 0.3.0 Here's the patch to up the library to the sysfsutils-0_3_0 level. The following changes: 1) adds class name to sysfs_class_device structure 2) adds bus to sysfs_device 3) gets rid of code that made assumptions as to bus addresses being unique across buses, which isn't the case. I still owe you: 1) change getpagesize->sysconf. This is in the CVS tree and part of other changes we're currently testing. Patch will follow. 2) you need a function to get a sysfs_class_device's parent. We hadn't considered class devices to have parents, the one example of a multilevel is the block class. We will add this function and send the patch to you.
