dwarf_getsrc_file cross-platform issue
by Mike Lindahl 04 Jan '10

04 Jan '10

Hello Roland and others, I found an issue with dwarf_getsrc_file() and its ability to support a combination of Windows and UNIX slashes ('\\' vs. '/'). The problem occurs when I load an ELF file that was built on Windows and has relative paths to source files (i.e. "dir\\file.c"). The logic in dwarf_getsrc_file() currently handles this as a basename path (is_basename is true). In this case, it will compare "dir\\file.c" with basename("dir/file.c"), which will always fail. The fix for this is to check for the presence of either a '/' or '\\' in the filename passed into the function. Once this is fixed, there's still the issue of using a straight strcmp() to compare the paths, which fails because the separator is different (I always use '/' as my separator on Linux - I haven't found an easy way to determine which separator to use for a given ELF file, but maybe someone has a suggestion here and I could change my application code instead). But it would be nice if libdw handled ELF files built on both Windows and Linux seamlessly. I propose the changes below to fix these issues (note that this diff is against 0.142, but nothing has changed in this file since then). I'm certain that this is not the most elegant way to solve the problem, so if someone wants to improve on this and get it into the trunk, that would be most excellent. Please let me know if I can provide any additional information to help get this fixed. Also, I will happily test out any fixes if that would be helpful.

Miss Lackland transferred the recruits, and the trick was done." "But where was she during the nor'wester?" Sheldon asked. "At Langa-Langa. Ran up there as it was coming on, and laid there the whole week and traded for grub with the niggers. When we got to Tulagi, there she was waiting for us and scrapping with Burnett. I tell you, Mr. Sheldon, she's a wonder, that girl, a perfect wonder." Munster refilled his glass, and while Sheldon glanced across at Joan's house, anxious for her coming, Sparrowhawk took up the tale. "Gritty! She's the grittiest thing, man or woman, that ever blew into the Solomons. You should have seen Poonga-Poonga the morning we arrived--Sniders popping on the beach and in the mangroves, war-drums booming in the bush, and signal-smokes raising everywhere. 'It's all up,' says Captain Munster." "Yes, that's what I said," declared that mariner. "Of course it was all up. You could see it with half an eye and hear it with one ear." "'Up your granny,' she says to him," Sparrowhawk went on. "'Why, we haven't arrived yet, much less got started. Wait till the anchor's down before you get afraid.'"

MUDAH-MUDAHAN BERMANFAAT...
by Rina.Indria 17 Dec '09

17 Dec '09

Dear Rekan2, Mohon maaf kalau sudah pernah mendapat informasi serupa sebelumnya. Kenalkan saya Rina, mahasiswi salah satu universitas swasta di Bandung. Rina pengen berbagi informasi nih buat kita semua, mudah2an bermanfaat. Barangkali ada dari rekan2 yg sedang butuh dana/income dalam jumlah besar.. Rekan2 bisa baca cara mendapatkannya disini (silakan klik atau copy-paste link berikut ke browser anda): http://www.program5milyar.com/?id=sukses123 Iseng2 rina udah coba, dan hasilnya udah lumayan banget utk ukuran rina (lihat rincian income rina dibawah dan SCAN BUKU TABUNGAN rina terlampir). Jangan lupa lihat juga scan/print buku tabungan member lain di link website diatas (di menu Kesaksian). Program ini dijalankan secara online (maya), tapi uang yg dihasilkan betul2 riil. Ada transaksi, ada produk, logis, masuk akal, dan tidak ada satu pihak pun yg dirugikan dalam program ini.. Program ini dijalankan secara LEGAL & HALAL (penjelasan detail harap baca di websitenya, di menu Legal & Halal) Websitenya ( http://www.program5milyar.com/?id=sukses123 ) menjelaskan secara lengkap semua hal tentang program ini sampai sejelas2nya. Mungkin dipahami dulu aja sistem/cara kerja program ini secara keseluruhan di websitenya. Sistemnya tidak rumit, mudah sekali dipahami. Rina yakin, semua uneg2 / pertanyaan2 dari rekan2 pasti akan terjawab jika membaca semua materi yg ada pada setiap menu di website tsb. Pastikan rekan2 tidak mengambil kesimpulan/berkomentar apa2 dulu sebelum betul2 membaca semua materi yg ada pada setiap menu di website, karena program5milyar ini unik, berbeda dg bisnis manapun yg pernah ada. Rina dulu juga gabung atas ajakan teman yg udah duluan mendaftar. Tadinya sih rina gak mau berpikir muluk2, asal bisa balik modal aja udah cukup, lagian kita kan dapat produk yg nilainya bahkan lebih besar dari yg kita bayarkan. So, nothing to loose. Tapi ternyata apa yg rina peroleh sungguh di luar perkiraan rina. Setelah 8 bulan gabung udah lumayan banget dapatnya. Rincian income Rina setelah 8 bulan gabung adalah sbb: (catatan: semua komisi dibawah ditransfer langsung oleh member baru ke rekening kita) Rina dapat member langsung sebanyak 17 orang (disebut member level-1) => komisi yg ditransfer ke rekening Rina = 17 x Rp 50.000 = Rp 850.000 Masing2 member level-1 diatas mendapatkan pula member rata-rata sebanyak 8 orang (disebut member level-2, jumlah = 8 x 17 = 136 orang) => komisi yg ditransfer ke rekening Rina = 136 x Rp 10.000 = Rp 1.360.000 Masing2 member level-2 rata2 mendapatkan member 6 orang (disebut member level-3, jumlah = 6 x 136 = 816 orang) => komisi yg ditransfer ke rekening Rina = 816 x Rp 10.000 = Rp 8.160.000 Masing2 member level-3 rata2 mendapatkan member 4 orang (disebut member level-4, jumlah = 4 x 816 = 3264 orang) => komisi yg ditransfer ke rekening Rina = 3264 x Rp 10.000 = Rp 32.640.000 Masing2 member level-4 rata2 mendapatkan member 3 orang (disebut member level-5, jumlah = 3 x 3264 = 9792 orang) => komisi yg ditransfer ke rekening Rina = 9792 x Rp 50.000 = Rp 489.600.000 Jadi, total komisi yg ditransfer ke rekening Rina (setelah 8 bulan gabung): = 850.000 + 1.360.000 + 8.160.000 + 32.640.000 + 489.600.000 = Rp 532.610.000,- Bagaimana dana tsb bertubi2 masuk ke rekening kita? Lihat SCAN BUKU TABUNGAN Rina terlampir. Lumayan banget utk ukuran rina. Uang segitu mungkin udah cukup utk beli rumah and mobil. Rina yakin kita semua bisa kok mendapatkan income seperti yg Rina dapatkan di atas. Kuncinya sih asal kita rajin aja nyebarin link website replika kita ke teman2 kita, rekan kerja, sodara, ke siapa saja, baik lewat email, milis2, situs2 iklan, dll, kemudian TUNJUKKAN BUKTI SCAN BUKU TABUNGAN para member yg telah sukses di program ini, atau scan buku tabungan anda jika anda sudah mendapatkan income yg lumayan di program ini, biasanya tidak terlalu sulit meyakinkan teman2 kita utk bergabung (scan buku tabungan para member bisa diambil/didownload di menu Kesaksian di website diatas, atau bisa juga gunakan scan buku tabungan rina terlampir. Jika anda sudah mendapatkan income lumayan di program ini, anda juga bisa tunjukkan scan buku tabungan anda ke teman2). Website replika adalah website atas nama kita sendiri yg kita dapatkan secara otomatis setelah keanggotaan kita diaktifkan. Website replika rina adalah: http://www.program5milyar.com/?id=sukses123 Setiap transaksi yg terjadi lewat website replika kita, otomatis masuk rekening kita. Tidak perlu kuatir pengembangan Program Program 5MILYAR ini akan jenuh, karena pertumbuhan pengguna internet di Indonesia yg mencapai 6 juta orang lebih per tahun jauh lebih besar dibanding pertumbuhan peserta program ini. Jadi program ini abadi, tidak akan ada istilah member terakhir dalam program ini, karena akan selalu ada 6 juta orang lebih pengguna baru internet tiap tahunnya yg potensial utk jadi member. RINA PUNYA TRIK2 / TIPS2 JITU agar bisa merekrut banyak member berdasarkan pengalaman rina sendiri, gak banyak orang yg tahu. Rina bisa share jika rekan2 bergabung lewat account rina: http://www.program5milyar.com/?id=sukses123 Segera gabung ya.. Sistemnya rina rasa sangat sederhana dan mudah dipahami, informasi lengkap disini (silakan klik atau copy-paste link berikut ke browser anda): http://www.program5milyar.com/?id=sukses123 (website replika Rina, sukses123 adalah username Rina) Mohon disebarkan juga informasi ini ke teman2 kita yg lain yg sedang membutuhkan dana dlm jumlah yg besar. Salam, Rina Rina Profile: http://www.friendster.com/rinaku Join jadi member Friendster dulu, bisa lihat album foto Rina UANG BUKAN SEGALANYA, TAPI SEGALANYA PERLU UANG NB: Jika anda tidak punya akses internet di kantor/kampus, silakan copy/tulis link berikut: http://www.program5milyar.com/?id=sukses123 kemudian dibuka di rumah/warnet ya.. Untuk gambaran awal, silakan lihat overview program ini terlampir. ************************************************************************* KESAKSIAN MEMBER LAIN, PAK BAMBANG WIDJATMOKO DARI SURABAYA: Bisa Menguliahkan Anak dan Biaya Berobat Ibu yg Sakit Dear webmaster program 5 milyar, Saya ingin berterima kasih sekali kepada anda karena dengan adanya program ini saya betul2 terbantu dalam pemenuhan berbagai kebutuhan dana keluarga saya. Biaya ibu berobat ke rumah sakit, biaya kuliah anak2, dan insya Allah untuk biaya beli rumah yg lebih layak bulan depan (mudah2an). Awalnya saya kenal program ini, saya mendapat email dari seorang teman (beda kantor). Ada program bisnis bagus nih, katanya. Sistemnya sederhana, gampang dipahami, dan kalo sabar bisa mendapatkan penghasilan lebih dari 5 milyar, tambahnya lagi. Mendengar kata-kata 5 milyar, saya berpikir skeptis, mana mungkin, batin saya, akhirnya saya delete saja email tsb. Sekitar 4 bulan setelah itu, saya mendapatkan email yg sama dari rekan yg berbeda. Dengan semangat menggebu2 di emailnya dia bercerita kalo dalam waktu sebulan dia bergabung, saldo di rekening BNI-nya bertambah lebih dari Rp 100 juta. Saya berpikir, gak mungkin dua orang sahabat baik saya berbohong tentang hal yg sama terhadap saya. Lagi pula gak ada ruginya bergabung, toh cuma 180 ribu saja, itu pun sudah dapat produk berupa program bisnis. Akhirnya, iseng2 saya gabung, tanpa harapan yg berlebihan. Kemudian saya informasikan program ini lewat email, sms, mulut ke mulut, dll ke sekitar 80 orang. Sebagian dari mereka ada yg saya kenal dan ada juga yg tidak, setelah itu saya lupakan. Sekitar 3 bulan setelah itu, waktu saya menyetor uang ke bank (jumlahnya sekitar 500 ribu waktu itu), waktu buku tabungan saya di-print saya menunggu lama sekali, teller-nya bilang buku tabungan saya sudah tidak muat lagi dan harus diganti dengan yg baru. Saya kaget, ada apa? Rasanya dalam 3 bulan terakhir saya tidak melakukan transaksi apa2. Begitu saya cek, di kolom kredit isinya 50 ribu dan 10 ribu banyak sekali dan di kolom saldo tercetak angka 160 juta lebih dan jika ditambah dengan buku ke 2 totalnya ada 250 juta sekian. Sontak saya kaget, ini duit begitu banyak dari mana? Setelah berpikir keras dan melihat angka 50 ribu dan 10 ribu baru saya teringat program 5 milyar yg saya pernah gabung dulu karena waktu gabung saya juga mentransfer 50 ribu dan 10 ribu ke beberapa orang. Aduh maaak, terima kasih Tuhan, terima kasih webmaster. Saya bisa kuliahkan anak dan membantu biaya berobat ibu saya yg sakit dengan dana ini. Setelah itu saya betul2 percaya bahwa program bisnis ini bener2 bekerja. Sejak itu saya mulai aktif mempromosikan program ini ke siapa saja, lewat email, milis, sms, dll. Sekarang hasilnya sudah lebih dari 500 juta masuk ke rekening bank saya. Sekali lagi terima kasih webmaster program 5 milyar. ------------------------------------------------------------------------------------------------------------ Untuk melengkapi hidup Anda, kini telah hadirProtector Postpaid untuk Pelanggan Speedy hanya dengan Rp 8000/bulan, layanan keamanan online yang dapat digunakan langsung saat menjelajahi internet, melindungi Anda dari Virus kapan saja dan di mana saja.

Last week + today ----------------- Time spent on elfutils: ~50% writer: * Emit .debug_ranges * Emit .debug_loc * dwarfcmp ./a.out ./a.out.out now works It's on pmachata/dwarf-writer. Next in plan ------------ * Merge in dwarf branch. * Make dwarfcmp work for bigger files. * We can't optimize certain references right away. For these we now pick the biggest form available. We could shrink these fields afterwards. But the codebase is not ready for this, e.g. gaps have to be able to move, size of ElfData has to be patched, etc. So work on preparing these bits, they will be useful later. PM
